Utmost Good Faith, Disclosure and Representations under the Marine Insurance Act 1906

Utmost Good Faith, Disclosure and Representations under the Marine Insurance Act 1906

Utmost good faith, disclosure, and representations under the Marine Insurance Act 1906 relate to how the insurer and insured should handle material circumstances relevant to underwriting decisions before concluding a marine insurance contract.

Sections 17 to 20 of the MIA 1906 established the traditional framework, positioning marine insurance contracts as contracts of utmost good faith and requiring disclosure and representation by the insured and their arranging agents during contract negotiations.

Section 21 of MIA 1906 provides that a marine insurance contract is formed when the insurer accepts the insured’s proposal. The contract may be considered formed even if the insurance policy document has not yet been issued, provided acceptance can be confirmed.

However, the current UK legal framework has significantly changed with the Insurance Act 2015. Sections 18 to 20 of MIA 1906 were repealed, and for non-consumer insurance contracts, the focus shifted to the insured’s duty of Fair Presentation of the Risk.

Moreover, under the traditional system, insurers could avoid the contract based on breaches of duty of disclosure or material misrepresentation. Under the current regime, a distinction is made between deliberate or reckless breaches and other breaches, with remedies aligned to the underwriting decisions the insurer would have made if properly informed.

This article explains the historical traditional framework under MIA 1906, followed by the current system under the Insurance Act 2015, including information transmission in marine cargo insurance, timing of contract formation, and the relationship with ICC(A), ICC(B), and ICC(C) clauses.

Purpose and Background of the System

In marine insurance, it is difficult for the insurer to directly investigate the cargo, vessel, voyage, packing, storage conditions, and transportation route before the contract is concluded.

Information regarding the nature of the cargo and transportation conditions is usually dispersed among the shipper, seller, buyer, manufacturer, freight forwarder, warehouse operator, and other involved parties.

Therefore, it has been a premise of marine insurance contracts that the proposer must properly present circumstances that could affect the insurer’s acceptance decision, premium, deductible, coverage terms, or special clauses.

On the other hand, the traditional system sometimes imposed overly strict effects through the right of avoidance for breach of disclosure obligations. Even when important information was omitted unintentionally, the insurer could potentially avoid the entire contract retrospectively.

The Insurance Act 2015 introduced changes requiring the insured to conduct a reasonable search and provide a clear presentation of the risk, while aligning remedies for breaches with the underwriting decision the insurer would have made if properly informed.

Traditional Principle of Utmost Good Faith

Section 17 of the Marine Insurance Act 1906 established marine insurance contracts as contracts based on utmost good faith.

Under the traditional statutory provision, if utmost good faith was not observed by either party, the other party was entitled to avoid the contract.

Avoidance does not merely mean terminating the insurance contract prospectively. It is a strong remedy under which the contract is treated as having been ineffective from the outset.

The Insurance Act 2015 abolished the general right of avoidance based solely on a breach of utmost good faith.

Therefore, it should no longer be understood that any breach of utmost good faith automatically invalidates the entire contract. The remedies defined under the specific rules governing disclosure, representations, warranties, fraudulent claims, and other matters must be confirmed.

Traditional Duty of Disclosure for the Insured

Under former Section 18 of the MIA 1906, the insured was required to disclose to the insurer, before contract formation, every material circumstance known to the insured.

Material circumstances are circumstances that would influence the judgment of a prudent insurer in fixing the premium or determining whether to accept the risk.

Materiality is not determined solely by whether the insured subjectively considered the circumstance important. It is judged objectively by whether the circumstance would affect the underwriting decision of a prudent insurer.

However, the mere existence of information about the cargo type or transport conditions does not automatically make all such information material. Materiality is assessed by considering the cargo, route, period, packing, past claims, and applicable policy terms.

Circumstances That May Be Important in Marine Cargo Insurance

Circumstance	Reason for Potential Impact on Underwriting Decision	Supporting Documents	Practical Presentation Method
Hazardous or Regulated Cargo	Risks of ignition, explosion, leakage, regulatory non-compliance, and handling restrictions	SDS, Dangerous Goods Declaration, and UN Number	Present the official product name, classification, quantity, and packing
Refrigerated or Frozen Cargo	Additional conditions may be required for temperature variation and equipment failure	Set temperature, permitted range, and storage duration	Clarify the cargo characteristics and temperature-control conditions
Used Machinery or Secondhand Goods	Pre-shipment condition, internal faults, and existing damage are relevant	Inspection records, photographs, and operational tests	State that the goods are used and describe their condition
Deck Cargo	Exposure to seawater, loss overboard, and weather increases the risk	B/L, Booking information, and stowage conditions	Present the planned or possible deck carriage in advance
Special or Insufficient Packing	Affects resistance to ordinary transit and the possible application of packing exclusions	Packing specifications, photographs, and packer records	Explain any non-standard packing method
Long-Term Storage or Interruption of Transit	Affects theft, deterioration, temperature variation, and the insurance period	Transport process, storage location, and storage duration	Disclose storage extending beyond the ordinary course of transit
Special Routes or High-Risk Areas	War, sanctions, piracy, port closure, and other risks may affect underwriting	Route, transshipment ports, and destination	Present the planned route and any alternative route
Multiple Transshipments	Additional handling increases the risk of damage and loss	Transport plan, Booking, and contract of carriage	Present the number and location of transshipments
Past Accidents or Claims	Affects risk frequency, risk management, and premium rating	Accident list, causes, and corrective measures	Organize the relevant period, number of incidents, and improvements
Insurance Arranged after Shipment	Raises issues concerning known incidents, existing damage, and adverse selection	Shipment date, time of knowledge of any incident, and application time	Clearly state that shipment has already occurred

These are examples of circumstances that may be material and do not always lead to the same conclusion. Their significance depends on the individual insurance contract and their effect on the judgment of a prudent insurer.

Circumstances Traditionally Considered Not to Require Disclosure

Circumstance	Basic Concept	Practical Notes
Circumstances That Reduce the Risk	A circumstance that reduces the risk may not require disclosure unless the insurer asks about it	Active disclosure may still be necessary when requesting a premium reduction.
Information Actually Known by the Insurer	Disclosure of the same information may not be required again	Do not confuse information known by an individual contact with information known by the insurer as an organization.
Information Presumed to Be Known by the Insurer	Generally known matters or information an insurer ought to know in the ordinary course of its business	The insurer is not necessarily presumed to know information specific to an individual cargo.
Circumstances for Which the Insurer Has Waived Disclosure	Matters the insurer has agreed need not be disclosed	The scope of the waiver should be confirmed in an email, questionnaire, or other record.
Circumstances Rendered Superfluous by a Warranty	Matters covered by an express or implied warranty may not require separate disclosure	The existence of a warranty does not necessarily remove the need to disclose every related circumstance.
Circumstances Waived through the Insurer’s Questions	The questions and underwriting process may limit the scope of required disclosure	When the position is unclear, confirm it rather than omitting information based on an internal assumption.

Effect of a Traditional Breach of the Duty of Disclosure

Under the traditional system of former Sections 18 and 20 of the MIA 1906, if there was non-disclosure of a material circumstance or a material misrepresentation, the insurer was entitled to avoid the contract.

This strict remedy could apply even when there was no direct causal connection between the loss that occurred and the undisclosed matter.

For example, if the insured failed to disclose that the cargo was frozen and the cargo was subsequently stolen in circumstances unrelated to temperature, avoidance could still have arisen under the traditional system if the frozen nature of the cargo was material to the insurer’s underwriting decision.

For current non-consumer insurance contracts, the duty of Fair Presentation of the Risk and the statutory remedies under the Insurance Act 2015 must be considered.

Information Transmission by Agents

Under former Section 19 of the MIA 1906, an agent arranging insurance was required to communicate to the insurer every material circumstance known to the agent or that the agent ought to have known in the ordinary course of business, together with every material circumstance the insured was required to disclose.

Under current law, the central question is whether the insured made a Fair Presentation of the Risk, including information the insured knew and information the insured ought to have known following a reasonable search.

When a freight forwarder is involved in transmitting information relating to cargo insurance, whether the freight forwarder acts as an agent for insurance purposes or merely as a point of contact providing transport information depends on the contractual relationships.

It should not be assumed that information known by the freight forwarder automatically constitutes knowledge of the insured or that communication to an insurance agent necessarily establishes that the information reached the insurer.

Verification by Information Holder

Information Holder	Information Likely Held	Relation to Fair Presentation of the Risk	Practical Measures
Insured’s Management	Overall transactions, past incidents, and special conditions	Likely to constitute knowledge of the corporate insured	Confirm management information affecting underwriting
Insurance Arrangement Staff	Insurance terms, questionnaires, and past claims	Important as the knowledge of persons responsible for arranging insurance	Collect information from the sales and logistics departments
Logistics Personnel	Routes, transshipment, packing, and storage	Information that may need to be identified through a reasonable search	Use a checklist before arranging insurance
Manufacturing or Quality-Control Personnel	Temperature, hazards, materials, and possible quality deterioration	May hold material information about the cargo	Obtain the SDS, specifications, and storage conditions
Freight Forwarder	Booking, routes, transshipment, and shipment dates	May be an external information holder within the scope of a reasonable search	Clarify the freight forwarder’s role and information-transmission route
Packing Contractor	Packing materials, securing methods, and packing limitations	May know about special or unsuitable packing	Obtain packing specifications and work records
Insurance Agent or Broker	Insurer questions, underwriting conditions, and requests for additional documents	It is necessary to confirm on whose behalf the agent or broker is acting	Record the information transmitted and confirmation of receipt
Insurer	Existing contracts, past claims, and general market information	Matters known or that ought to be known by the insurer may not require disclosure	Do not rely excessively on information presumed to be known by the insurer

Representations During Contract Negotiations

Under former Section 20 of the MIA 1906, every material representation made by the insured or the insured’s agent during contract negotiations was required to be true.

Representations may relate to facts or to expectations and beliefs.

A representation of fact must be substantially correct. If the difference between the representation and the actual facts would not be material to the assessment of a prudent insurer, the representation may be regarded as substantially correct.

A representation relating to an expectation or belief is not untrue merely because the outcome differs from what was anticipated. The relevant question is whether the representation was honestly made at the time.

Type of Representation	Example	Required Standard	Example of a Problematic Representation
Current Fact	The cargo is new	Substantially correct	Representing refurbished used machinery as new
Nature of the Cargo	The cargo is not classified as dangerous goods	Accurate according to the relevant classification documents	Describing the cargo as non-dangerous when the SDS identifies it as dangerous goods
Packing Condition	The cargo is fully packed in export wooden cases	Consistent with the actual packing	Failing to disclose that only simple or unsuitable packing was used
Future Plan	The cargo is scheduled to move by direct service	Based on a reasonable plan at the time of representation	Representing the movement as direct when transshipment had already been confirmed
Expectation	The storage period is expected to be approximately three days	Based on an honest estimate	Stating a short storage period when long-term storage was already expected
Belief	The cargo is believed to be in sound condition at shipment	Honestly held and based on reasonable information	Representing the cargo as sound despite knowledge of an existing defect

Withdrawal and Correction of Representations

A representation made during contract negotiations may generally be withdrawn or corrected before the insurance contract is concluded.

If the cargo type, quantity, dangerous-goods classification, vessel name, route, transshipment, packing, temperature-control condition, or shipment date changes after the insurance application, the corrected information should be communicated before the insurer accepts the proposal.

Sending a correction is not sufficient by itself. It is important to confirm that the correction reached the insurer or a person with underwriting authority and that the revised risk was accepted.

If a change becomes known after the contract has been concluded, the issue may concern a change in risk, amendment of the contract, or additional cover rather than correction of a pre-contract representation.

Timing of Contract Formation under Section 21 of the MIA 1906

Under Section 21 of the MIA 1906, a marine insurance contract is concluded when the insurer accepts the insured’s proposal for insurance.

The contract may therefore be formed even if the insurance policy has not yet been issued or delivered, provided the insurer’s acceptance can be established.

When determining the time of contract formation, slips, cover notes, acceptance emails, underwriting-system records, and other customary contractual memoranda may be important evidence.

However, the mere issue of a quotation, submission of a proposal form, or instruction to an insurance agent does not necessarily establish that the insurer has accepted the proposal.

Chronology of Insurance Arrangement

Timing	Main Event	Relation to Contract Formation	Supporting Documents
Request for Quotation	Cargo and transport conditions are presented	Usually occurs before contract formation	Quotation request email and questionnaire
Quotation Provided by the Insurer	Premium and proposed terms are presented	A quotation alone may not constitute acceptance	Quotation and proposed terms
Insured’s Proposal	Cover is requested on the proposed terms	Insurer acceptance remains outstanding	Proposal form and cover request email
Insurer’s Acceptance	The insurer confirms acceptance of the risk	Generally the point of contract formation	Acceptance email and underwriting-system records
Cover Note Issued	Provisional evidence of the contract is issued	May provide evidence of acceptance	Cover note
Insurance Policy Issued	The formal insurance policy is created	May occur after contract formation	Insurance policy and issuance records
Commencement of Cargo Risk	Insured transit begins under the applicable clauses	Separate from the time of contract formation	Pickup records, gate-out records, and applicable policy clauses
Occurrence of an Incident	Loss of or damage to cargo occurs	Both contract formation and commencement of risk must be confirmed	Incident report and timestamped records

Fair Presentation of the Risk under the Insurance Act 2015

Under the Insurance Act 2015, the insured under a non-consumer insurance contract has a duty to make a Fair Presentation of the Risk before the contract is concluded.

This duty also applies before a variation of the insurance contract.

A Fair Presentation of the Risk generally requires disclosure of every material circumstance that the insured knows or ought to know.

Where every material circumstance is not specifically disclosed, the insured may instead provide sufficient information to put a prudent insurer on notice that further enquiries are required.

Merely sending a large volume of unorganized documents in which important information is concealed or obscured may not satisfy the duty. The presentation must be reasonably clear and accessible to a prudent insurer.

Requirements for Fair Presentation of the Risk

Requirement	Content	Appropriate Example	Problematic Example
Disclosure of Material Circumstances	Disclose material circumstances known or that ought to be known	List hazardous goods, temperature requirements, route, and accident history	Omit material information because the insurer did not specifically ask about it
Information Prompting Further Enquiries	Provide sufficient information to make the insurer aware that further questions are required	State that used machinery is under investigation for possible existing defects	Describe the subject matter only as machinery without further information
Clarity	Present material information in a comprehensible form	Match a risk summary with numbered supporting documents	Bury material circumstances in a large volume of attachments
Accessibility	Make the information reasonably accessible to the insurer	Use clear filenames, an index, and explanatory notes	Provide inaccessible files or ambiguous links without explanation
Accuracy of Factual Representations	Every material representation of fact must be substantially correct	Use official documents to state item descriptions and quantities	Describe hazardous goods as ordinary merchandise
Good Faith in Expectations and Beliefs	Representations of expectation or belief must be made in good faith	Identify unresolved matters as planned, expected, or under confirmation	Present an uncertain matter as a confirmed fact
Reasonable Search	Conduct a reasonable search of available internal and external information	Check with logistics, quality-control, sales, and freight-forwarding personnel	Rely only on information already known by the insurance contact

Information Known or Ought to Be Known by the Insured

For a corporate insured, information known by individuals who form part of senior management and by persons responsible for arranging the insurance is relevant.

In addition, information that would have been revealed by a reasonable search of information available to the insured may be treated as information the insured ought to know.

A reasonable search is not necessarily confined to the insurance department. It may include information held by the logistics department, quality-control department, manufacturing department, affiliated companies, freight forwarders, packers, and other relevant parties.

This does not impose an unlimited obligation to investigate every possible party. Reasonableness depends on the size and nature of the business, the contract, the characteristics of the cargo, access to information, and ordinary business practices.

Conditions for Establishing a Breach of the Duty of Fair Presentation

A deficiency in the Fair Presentation of the Risk does not automatically entitle the insurer to a remedy.

The insurer must show that, but for the breach, it would not have entered into the contract at all or would have entered into it only on different terms.

A breach that satisfies this requirement is commonly described as a qualifying breach because it affected the underwriting decision the insurer would have made.

A qualifying breach is categorized as deliberate or reckless, or as neither deliberate nor reckless.

A breach may be deliberate or reckless if the insured knew that it was in breach of the duty of fair presentation or did not care whether it was in breach.

Remedies for Breach of the Duty of Fair Presentation

Type of Breach	Underwriting Decision the Insurer Would Have Made	Main Remedy	Treatment of Premium
Deliberate or Reckless	The statutory conditions for a deliberate or reckless qualifying breach are satisfied	The insurer may avoid the contract and refuse all claims	The insurer may retain the premium
Neither Deliberate nor Reckless	The insurer would not have entered into the contract	The insurer may avoid the contract and refuse the claim	The premium is generally returned
Neither Deliberate nor Reckless	The insurer would have entered into the contract on different non-premium terms	The contract is treated as if those different terms had applied	Any premium difference is considered separately
Neither Deliberate nor Reckless	The insurer would have charged a higher premium	The claim payment is reduced proportionately by reference to the premium actually charged and the premium that should have been charged	A proportionate remedy applies
Neither Deliberate nor Reckless	The insurer would have imposed different terms and charged a higher premium	The different terms and the proportionate reduction may both apply	The calculation uses the premium that should have been charged
No Effect on Underwriting	The insurer would have entered into the contract on the same terms and for the same premium	No remedy for breach of the duty of fair presentation may be available	The contract continues on its actual terms

Numerical Example of a Proportionate Remedy

Assume that the premium actually charged was 100,000 yen and that the insurer would have charged 150,000 yen if the correct information had been presented.

If the claim amount before the proportionate reduction is 9,000,000 yen, the proportionate payment percentage is calculated as follows.

Payment Percentage = Premium Actually Charged 100,000 yen ÷ Premium That Would Have Been Charged 150,000 yen = 66.67%

Reduced Payment = 9,000,000 yen × 66.67% = approximately 6,000,000 yen

Therefore, where the breach is neither deliberate nor reckless and the insurer proves that it would have charged only a higher premium, the basic payment after the proportionate reduction is approximately 6,000,000 yen.

This is a simplified explanatory example. In practice, any deductible, special clause, coverage restriction, or other term that the insurer would have imposed must also be considered.

Comparison between the Traditional and Current Systems

Comparison Item	Former Sections 18–20 of the MIA 1906	Insurance Act 2015	Main Change	Practical Response
Core Obligation	Duty of disclosure and truthfulness of material representations	Duty of Fair Presentation of the Risk	Disclosure, representations, and reasonable search are integrated	Create a risk summary
Scope of Information	Material circumstances known by the insured or the insured’s agent	Circumstances known or that ought to be known following a reasonable search	A reasonable search is expressly required	Identify information holders inside and outside the organization
Method of Presentation	Focused on disclosure of individual material circumstances	Requires a reasonably clear and accessible presentation	Discourages unstructured submission of large volumes of documents	Attach an index and summary
Insurer Enquiries	Emphasized voluntary disclosure by the insured	Permits sufficient information that alerts the insurer to the need for further enquiries	The insurer’s follow-up questions are also relevant	Identify uncertainties and invite further enquiries
Remedies for Breach	Contract avoidance was the principal remedy	Remedies correspond to the underwriting decision the insurer would have made	Introduces proportionate and terms-based remedies	Confirm the nature of the breach and the counterfactual underwriting terms
Premium	Return of premium arose when the contract was avoided	Treatment depends on whether the breach was deliberate or reckless	The insurer may retain the premium for a deliberate or reckless breach	Classify the breach correctly

Relationship with ICC(A), ICC(B), and ICC(C)

ICC(A), ICC(B), and ICC(C) are standard clauses defining insured risks, exclusions, the insurance period, and post-loss obligations under marine cargo insurance.

The duty of Fair Presentation of the Risk is a pre-contractual obligation under UK insurance law. The Institute Cargo Clauses do not replace that legal duty.

Information concerning the cargo, packing, voyage, and transport conditions presented before contract formation may nevertheless affect the application of the ICC, special clauses, deductibles, warranties, and additional premiums.

Issue	Relation to the Duty of Fair Presentation	Relation to ICC or the Insurance Policy	Practical Point
Type and Nature of Cargo	May constitute a material circumstance before contract formation	Affects coverage conditions, inherent-vice exclusions, and special clauses	Present the actual nature of the cargo, not merely a general product name
Packing	Unusual or unsuitable packing may be material	ICC Clause 4 concerning insufficient or unsuitable packing may apply	Record the packing party, time, method, and specifications
Voyage and Destination	May affect acceptance and premium rating	Affects the insurance period, changes of voyage, and war risks	Promptly notify any change
Insurance Arranged after Shipment	Knowledge of incidents or existing damage may be material	Pre-existing damage, insurable interest, and the insurance period must be checked	Accurately record what was known at the time of application
Special Clauses and Warranties	May be imposed in response to the risk presented	Incorporated into the policy separately from the standard ICC	Do not confuse the duty of fair presentation with compliance with contractual terms
Post-Loss Mitigation	Separate from the pre-contractual presentation duty	ICC Clause 16 requires reasonable measures and preservation of rights against third parties	Prevent further loss and preserve recovery rights after an incident
Reasonable Dispatch	Separate from pre-contractual information presentation	The ICC Avoidance of Delay provision may be relevant	Act with reasonable dispatch in circumstances within the insured’s control

Practical Workflow for Applying the System

1. Confirm the governing law and contract type
   Verify whether the insurance is a non-consumer contract governed by UK law.
2. Identify the subject matter insured
   Organize the cargo, quantity, value, transport route, and insurable interest.
3. List potentially material circumstances
   Check hazardous classification, temperature requirements, packing, route, transshipment, storage, and accident history.
4. Identify information holders
   Confirm relevant management, insurance, logistics, quality-control, manufacturing, and freight-forwarding personnel.
5. Conduct a reasonable search
   Review available internal and external documents and obtain information from relevant personnel.
6. Distinguish facts from expectations
   Separate confirmed facts, plans, assumptions, beliefs, and matters under investigation.
7. Create a risk summary
   List the material circumstances and cross-reference supporting documents.
8. Present the information clearly and accessibly
   Do not bury important information in a large volume of documents.
9. Respond to insurer enquiries
   Retain records of questions, answers, and the basis for each answer.
10. Correct changes or errors
    Promptly notify the insurer of any change discovered before contract formation.
11. Confirm the insurer’s acceptance
    Retain acceptance emails, cover notes, and underwriting records.
12. Manage conditions after contract formation
    Confirm warranties, notification requirements, changes of risk, and obligations under the ICC.

Cases Commonly Problematic in Practice

Case	Main Issue	Documents for Verification	Key Point for Judgment	Initial Response
Hazardous goods declared as general cargo	Disclosure of material circumstances and accuracy of representations	SDS, Dangerous Goods Declaration, and application form	Would the correct classification have affected the underwriting decision?	Immediately notify the correct classification
Used machinery not declared as used	Cargo condition and pre-existing damage	Invoice, inspection records, and photographs	Would different terms have applied to used machinery?	Submit condition documents for reconsideration
Incorrect temperature setting stated for refrigerated cargo	Accuracy of a factual representation or honesty of an estimate	Product specifications, temperature instructions, and application form	Was the representation substantially correct and honestly made?	Correct it before contract formation
Freight forwarder knew of transshipment arrangements	Reasonable search and attribution of information	Booking, transport plan, and emails	Was the information reasonably available to the insured?	Examine the information-transmission process
Route changed after quotation	Correction of a representation and timing of contract formation	Original route, revised route, and acceptance records	Did the change occur before or after acceptance?	Obtain acceptance on the revised terms
Incident occurred before policy issuance	Contract formation under Section 21 of the MIA 1906	Proposal, acceptance, and cover note	Had the insurer accepted the proposal before the incident?	Secure timestamped records
Insurance arranged after shipment	Known damage and Fair Presentation of the Risk	Shipment time, application time, and time of knowledge of any incident	Did the applicant know of any incident or abnormality when applying?	Clearly disclose that shipment has already occurred
Only part of the past claims history disclosed	Incomplete disclosure of material information	Accident records, claims history, and questionnaires	Did the incomplete presentation mislead the insurer?	Submit the complete history and corrective measures
Large volume of documents sent without explanation	Clarity and accessibility of the presentation	Files sent, index, and accompanying emails	Could a prudent insurer reasonably identify the material information?	Resubmit the information with a summary and document numbering

Application Scenario 1: Failure to Disclose Hazardous-Goods Classification

Assume that a chemical product is insured as general cargo and that, after the contract is concluded, it is discovered that the cargo is dangerous goods with a UN number.

The dangerous-goods classification may be a material circumstance affecting the insurer’s acceptance decision, premium, and special conditions.

If the insured knowingly represented the cargo as ordinary goods despite knowing that it was dangerous goods, this may constitute a deliberate or reckless breach.

If the insured received an incorrect SDS from the manufacturer and could not reasonably have identified the dangerous nature of the cargo after conducting a reasonable search, the breach may be neither deliberate nor reckless, or there may be no breach.

The insured’s knowledge, the scope of the reasonable search, the insurer’s underwriting decision, and the documents presented must be examined.

Application Scenario 2: Transshipment Information Known by the Freight Forwarder

The insured applies for insurance on the basis of a direct voyage, but the freight forwarder knows before contract formation that the cargo will be transshipped twice.

The number of transshipments may be material because it affects handling risks and the transport period.

The freight forwarder’s knowledge does not automatically constitute knowledge of the insured.

However, if the insured ordinarily obtains the transport plan from the freight forwarder and could readily have confirmed the transshipments through a reasonable search, the information may be treated as something the insured ought to have known.

The freight forwarder’s role, availability of the information, normal verification procedures, and time available before the insurance application should be examined.

Application Scenario 3: Correcting a Representation before Contract Formation

Assume that the cargo was initially represented as non-dangerous, but before the insurer accepted the proposal it was discovered to be dangerous goods and the representation was immediately corrected.

A representation may be withdrawn or corrected before the contract is concluded.

It is not sufficient merely to send a correction email. The insured should confirm that the insurer received the corrected information and accepted the risk on the revised basis.

If the insurer proposes an additional premium or special conditions, the contract is formed on the amended basis only when the revised proposal is accepted.

Application Scenario 4: Incident before Policy Issuance

Assume that the insured applied for cover at 10:00 a.m., the insurer accepted the risk by email at 11:00 a.m., a cargo incident occurred at 1:00 p.m., and the policy was issued the following day.

Under Section 21 of the Marine Insurance Act 1906, contract formation depends on the insurer’s acceptance, not on the later issue of the policy.

If the 11:00 a.m. email constituted unconditional acceptance and the insured transit under the applicable clauses had commenced by 1:00 p.m., the incident may fall within the contract even though the policy had not yet been issued.

If the 11:00 a.m. email was only a quotation response or was subject to internal approval, the conclusion may be different.

Application Scenario 5: Non-Deliberate Non-Disclosure and a Proportionate Remedy

Assume that the insured unintentionally omitted one previous incident and that the insurer would have charged a premium of 150,000 yen instead of 100,000 yen if the correct information had been presented.

If the breach was neither deliberate nor reckless and the insurer would still have accepted the risk for a higher premium, a proportionate remedy applies.

If the claim before reduction is 9,000,000 yen, the payment percentage is calculated by dividing the premium actually charged by the premium that should have been charged.

9,000,000 yen × 100,000 yen ÷ 150,000 yen = approximately 6,000,000 yen

The basic payment after the proportionate reduction is therefore approximately 6,000,000 yen.

Application Scenario 6: The Insurer Would Not Have Accepted the Risk

Assume that the insurer does not accept a particular type of explosive cargo and that the insured negligently failed to disclose the nature of the cargo accurately.

Even though the breach was neither deliberate nor reckless, the insurer may avoid the contract if it proves that it would not have entered into the contract on any terms had the correct information been presented.

The insurer may refuse the claim but must generally return the premium because the breach was neither deliberate nor reckless.

The insurer’s assertion that it would not have accepted the risk should be supported by underwriting guidelines, previous practice, and the contemporaneous underwriting record.

Common Misconceptions

Misconception	Actual Position	Practical Point
Sections 18 to 20 of the MIA 1906 still apply without modification	Those Sections were repealed, and the duty of Fair Presentation of the Risk now applies to non-consumer insurance contracts.	Distinguish the traditional and current regimes.
Every breach of utmost good faith automatically invalidates the entire contract	The general avoidance remedy based solely on utmost good faith has been abolished; the applicable statutory remedy must be identified.	Identify the type of breach and the underwriting decision affected.
Only matters expressly asked about must be disclosed	Material circumstances may require voluntary disclosure even if they were not the subject of a specific question.	Do not rely solely on the questionnaire.
Sending a large volume of documents necessarily constitutes a Fair Presentation of the Risk	The presentation must be reasonably clear and accessible.	Include a summary, index, and document references.
If the insurance contact does not know something, the corporate insured does not know it	Knowledge of senior management, insurance personnel, and information revealed by a reasonable search may be relevant.	Conduct a cross-departmental review.
Information known by the freight forwarder automatically constitutes knowledge of the insured	The position depends on the freight forwarder’s role, information access, and the scope of a reasonable search.	Do not assume automatic attribution.
An incorrect forecast is automatically a misrepresentation	A representation of expectation or belief is judged by whether it was honestly made when given.	Distinguish facts from forecasts.
A representation can be freely corrected after contract formation	Correction before acceptance differs from amendment of an existing contract.	Confirm the time of acceptance.
Sending an application form establishes the insurance contract	The insurer must generally accept the proposal.	Retain evidence of acceptance.
The contract cannot be formed until the policy is issued	The contract may be formed on acceptance before policy issuance.	Check cover notes, slips, and acceptance emails.
Every breach of the duty of Fair Presentation of the Risk reduces the claim to zero	For a breach that is neither deliberate nor reckless, different terms or a proportionate reduction may apply.	Confirm the underwriting decision the insurer would have made.
ICC Clause 16 imposes the pre-contractual duty of disclosure	ICC Clause 16 concerns post-loss measures to avert or minimise loss and preserve rights against third parties.	Distinguish pre-contract duties from post-loss obligations.

Do Not Confuse Utmost Good Faith, Fair Presentation, and Obligations under ICC

Utmost good faith is a foundational historical principle of marine insurance contracts.

Fair Presentation of the Risk is a current legal duty applying before a non-consumer insurance contract is entered into or varied. It requires the insured to present material circumstances clearly and accessibly to the insurer.

Warranties, special clauses, and notification requirements are contractual terms of the insurance contract after it has been formed.

ICC Clause 16 concerns measures taken after a loss to avert or minimise further loss and to preserve rights against third parties.

These concepts are related but differ in their timing, purpose, and consequences of breach.

Summary

Section 17 of the Marine Insurance Act 1906 established marine insurance contracts as contracts of utmost good faith.

Former Sections 18 to 20 of the MIA 1906 governed disclosure by the insured and agents and representations made during contract negotiations. Those Sections were repealed by the Insurance Act 2015.

Under current law for non-consumer insurance contracts, the insured must make a Fair Presentation of the Risk by disclosing material circumstances known or that ought to be known, or by providing sufficient information to put a prudent insurer on notice that further enquiries are required.

The insured may be treated as knowing information that would have been revealed by a reasonable search. For a corporate insured, this may require checking information held by management, persons arranging insurance, logistics, quality-control, manufacturing, and relevant external parties.

Representations of fact must be substantially correct, while representations of expectation or belief must be made in good faith.

The remedies for breach of the duty of fair presentation are not uniform. A deliberate or reckless qualifying breach may permit avoidance of the contract and retention of the premium. For a breach that is neither deliberate nor reckless, the remedy depends on whether the insurer would have declined the risk, imposed different terms, or charged a higher premium.

Section 21 of the MIA 1906 provides that the insurance contract is concluded when the insurer accepts the insured’s proposal. The policy issuance date, contract formation date, commencement of risk, and incident date must be distinguished.

ICC(A), ICC(B), and ICC(C) define coverage, exclusions, the insurance period, and obligations after contract formation. They do not replace the pre-contractual duty of Fair Presentation of the Risk.

When arranging marine cargo insurance, the insured should organize and promptly present information concerning the nature of the cargo, dangerous-goods classification, temperature requirements, packing, route, transshipment, storage, past claims, and shipment status, including changes and uncertainties.

Where a dispute concerns non-disclosure, contract avoidance, a proportionate remedy, or the time of contract formation, the policy, underwriting records, and communication history should be preserved, and advice should be obtained from the insurer, insurance agent, or a professional familiar with UK insurance law.
