Assignment of Policy under the Marine Insurance Act 1906

Assignment of Policy under the Marine Insurance Act 1906

Assignment of marine insurance policies under the UK Marine Insurance Act refers to the transfer of interests and rights under the marine insurance policy from the insured or other rights holders to a third party.

In marine cargo insurance for external trade, economic interests related to the cargo and rights under the insurance policy may transfer alongside transactions such as sale of goods, CIF contracts, letters of credit transactions, assignment of Bills of Lading, endorsement of insurance policies, and creation of security interests in favor of financial institutions.

Section 50 of the Marine Insurance Act 1906 (MIA 1906) provides that, unless expressly prohibited by the policy terms, the policy may be assigned either before or after a loss occurs.

Where the substantial interest in the policy has been validly transferred, the assignee may claim under the insurance contract in their own name.

However, assignment of the insurance policy does not extinguish exclusions, scope of coverage, insurance period, warranties, Fair Presentation of the Risk, or other issues existing under the original insurance contract.

The insurer may, in principle, assert against the assignee the same defenses they could have asserted against the original insured under the insurance contract.

Section 51 of MIA 1906 declares invalid any assignment made after the insured has parted with or lost their interest in the insured subject matter unless there was an assignment agreement made before or contemporaneously with the loss of interest.

Accordingly, the transfer of ownership, risk, or insurable interest in the cargo must be separately confirmed from the assignment of rights under the marine insurance policy.

Purpose and Background of the System

In international cargo transactions, even while cargo is in transit, economic interests related to the cargo may transfer among sellers, buyers, trading companies, banks, and other parties involved.

If marine insurance policies cannot be transferred, the party who actually bears the risk of the cargo and the party holding the rights under the insurance contract may be separate. This could result in an inappropriate party being unable to claim insurance proceeds in the event of a loss.

Therefore, Section 50 of the Marine Insurance Act 1906 (MIA1906) provides that, unless explicitly prohibited on the policy, marine insurance policies may be transferred either before or after a loss occurs.

At the same time, marine insurance is not intended as a mechanism for unrelated parties to acquire the policy alone and profit from it without interest in the insured object.

Section 51 of MIA1906 restricts the transfer of the policy alone after the insured has already abandoned or lost the insurable interest, unless there is a prior or simultaneous agreement to transfer.

These two provisions establish a structure that ensures the negotiability of policies necessary for international trade, while preventing the subsequent transfer of policies by parties who no longer hold an insurable interest.

Hierarchy of Terms Related to Policy Transfer

Term	Meaning	Main Subject	Timing to Confirm	Potential Issues if Confused
Assignor	The party transferring the interest on the insurance policy	Original insured or rights holder	At the time of transfer agreement	There is a risk of endorsement by a party without transfer authority.
Assignee	The party acquiring the interest on the insurance policy	Buyer, bank, trading company, etc.	Upon completion of the transfer	Assignee may be confused with the actual rights holder beyond mere policy possession.
Insurable Interest	The legal or economic relationship exposed to financial loss from an insured event	Cargo, freight, profits, etc.	As a rule, at the time of loss occurrence	It may be mistakenly assumed that mere possession of the policy allows a claim.
Substantial Interest on the Policy	The economic benefits and rights arising from the insurance contract	Claims for insurance proceeds, etc.	At the time of policy transfer	May be wrongly judged that rights transfer occurs solely by formal endorsement.
Claim Right to Insurance Proceeds	The right to demand payment under the insurance contract after an insured event	Compensation claims	After loss occurrence	Could be mistaken as a secured monetary claim with confirmed enforceability.
Endorsement	The method of indicating and signing the intention to transfer on the policy document	Marine insurance policy	Before or at policy handover	May be confused with mere receipt signature versus transfer endorsement.
Risk Burden	Who bears the economic burden of loss or damage to the item under sale	Seller or buyer	At the time of risk transfer under the sales contract	There is a misconception that risk burden transfer automatically transfers the policy.
Rights under Bill of Lading	Rights to demand cargo delivery and other rights under the carriage contract	Carried goods	At the time of B/L transfer	May be confused as identical to rights under the insurance contract.

Marine Insurance Policies Are Generally Transferable

Section 50(1) of the Marine Insurance Act 1906 (MIA1906) provides that a marine insurance policy may be transferred unless it explicitly contains conditions prohibiting such transfer.

Therefore, the general rule is that policies are transferable, but not all policies can be transferred unconditionally.

If the policy, certificate of insurance, open cover agreement, special clause, or insurer’s approval terms include prohibitions on transfer, prior approval requirements, or specify methods of transfer, those conditions must be verified.

Additionally, the transferability of the policy itself does not necessarily mean that the transferee’s claim for insurance proceeds will be recognized.

The effectiveness of the transfer, insurable interest, insured peril, insurance period, cause of loss, and insurer’s defenses must be examined separately.

Assignment Before the Occurrence of Damage

Assignment before the occurrence of damage refers to the transfer of interest under the policy to the buyer or other assignee while the cargo is still in transit or before transportation has commenced.

A typical example is in CIF transactions where the seller arranges marine cargo insurance and assigns the insurance policy along with the shipping documents to the buyer or a bank.

In assignments before the occurrence of damage, it is important that the assignee holds an insurable interest in the cargo at the time the damage occurs.

It should be confirmed that the endorsement of the policy, delivery of the policy, transfer of risk under the sales contract, and transfer of the Bill of Lading are properly coordinated.

If only the policy is transferred earlier but the assignee is not in a position to suffer economic loss at the time of the incident, there could be complications in claiming insurance proceeds.

Assignment After Loss Occurrence

Section 50 of the MIA 1906 explicitly allows for the assignment of marine insurance policies even after a loss has occurred.

Once a loss occurs, the insured party may acquire the right to claim insurance proceeds to the extent that the terms of the insurance contract are satisfied.

In an assignment after loss occurrence, the interest assigned under the policy includes the already arisen contractual claim.

However, the mere occurrence of an incident does not automatically establish an unconditional monetary claim for a fixed amount.

The obligation to pay and the amount are determined after verifying coverage risks, the insurance period, exclusions, insurable interest, the extent of loss, and necessary documentation.

Therefore, the assignee after loss occurrence takes over the claims process but also inherits any existing coverage issues under the original contract.

Comparison Between Assignment Before and After the Occurrence of Damage

Comparison Item	Assignment Before Damage	Assignment After Damage	Practical Points to Confirm
Timing of Assignment	Before the occurrence of the accident	After the occurrence of the accident	The accident date and time, as well as the date and time of endorsement/agreement, should be confirmed.
Main Subject of Assignment	Future insurance interest and rights under the policy	Policy benefits including already arisen claims	Confirm the scope of rights covered by the assignment wording.
Insurable Interest	It is important that the assignee has it at the time of damage occurrence	Confirm who had the insurable interest at the time of damage	The assignee after the accident may not be the party bearing the loss at the damage time.
Relationship with Section 51	An assignment agreement before or simultaneous with loss of interest may be required	The restrictions under Section 51 generally do not apply	Do not confuse before and after the accident.
Typical Examples	Assignment of policy from CIF seller to buyer	Transfer of claims from a trading company to a financial institution after the accident	Confirm the purpose of the transaction and the consideration for the assignment.
Insurer’s Defenses	Defenses existing before the assignment apply	Defenses related to the accident and contract apply	Assignment does not cure contractual defects.

The Assignee May Claim in Their Own Name

Section 50(2) of the Marine Insurance Act 1906 (MIA1906) provides that if a marine insurance policy is transferred in a way that conveys the substantial interest evidenced by the policy, the assignee may make a claim under the insurance contract in their own name.

The assignee may proceed not only as an agent of the original insured but also assert the rights evidenced by the policy to make a claim.

However, mere formal possession of the policy may be insufficient.

It is necessary to confirm the intention to transfer the substantial interest evidenced by the policy from factors such as endorsement, assignment deed, delivery of the policy, sales contract, payment settlement, and the agreement between the parties.

Furthermore, the assignee’s ability to claim in their own name is a separate issue from whether the conditions for payment of the insurance proceeds are fulfilled.

Insurer's Defenses Remain After Assignment

The assignment of a marine insurance policy does not replace the original insurance contract with a new unconditional contract.

Under Section 50(2) of the Marine Insurance Act 1906, the insurer may assert against the assignee any defenses that could have been raised under the original insurance contract.

Insurer's Defense	Example	Basic Treatment After Assignment	Reference Materials
Non-covered Risk	Claiming theft loss under ICC(C)	Non-coverage can be asserted against the assignee as well	Insurance policy, applicable ICC, incident report
Outside the Insurance Period	Incident occurring in final warehouse after insurance expiration	Insurance period is not extended by assignment of the policy	Delivery records, unloading records, incident date and time
Exclusions	Damage caused by insufficient packing or inherent defect	Exclusion applies against the assignee as well	Packing documentation, survey report
Warranties / Breach of Contract Terms	Deck stowage requiring approval carried out without consent	The breach is not removed by assignment	Special conditions, B/L, booking confirmation
Fair Presentation of the Risk Issue	Dangerous goods not disclosed at contract inception	Statutory remedies may be asserted against the assignee	Application form, SDS, underwriting records
No Insurable Interest	Claim by a party without economic loss at time of incident	Possession of the policy alone does not establish a valid claim	Sales contract, payment records, risk transfer documents
Insufficient Proof of Loss	Failure to prove cause of incident or quantity of damage	Assignee must also submit required evidence	Photographs, survey, receipts

Specific Examples of Defenses Available to the Insurer

Suppose the seller arranges insurance for cargo requiring temperature control as if it were ambient temperature cargo and then transfers the insurance policy to the buyer.

During transport, damage occurs due to a rise in temperature, and the buyer files a claim as the transferee of the policy.

Even if the policy has been validly transferred, if the original insurance contract did not properly present the cargo’s temperature conditions, this issue is not resolved by the transfer.

The insurer may be entitled to assert any remedies or defenses available under the original contract against the buyer as well.

The fact that the buyer acquired the policy in good faith does not automatically broaden the scope of coverage under the insurance contract.

Methods of Transferring Marine Insurance Policies

Section 50(3) of the MIA 1906 stipulates that marine insurance policies may be transferred by endorsement on the policy or other customary means.

This provision does not prescribe a single specific endorsement wording or format for all transactions.

In practice, depending on the form of the policy, terms of sale, letter of credit requirements, trade customs, and governing law, transfer methods may include registered endorsement, blank endorsement, separate transfer certificates, delivery of the policy, or other approaches.

What is essential is that the intention and subject matter of transferring the substantive interest in the policy to the transferee can be confirmed from the document and the transactional background.

Differences Between Registered Endorsement, Blank Endorsement, and Separate Assignment

Assignment Method	Basic Form	Practical Characteristics	Main Points to Confirm	Notes
Registered Endorsement	Endorser signs on the policy specifying the name of the assignee	Facilitates clear identification of the person acquiring rights	Company name, signature authority, assignment target	Check for errors in name spelling and differences in legal entity status.
Blank Endorsement	Endorser signs without specifying the assignee’s name	Often circulated together with delivery of the policy	Policy form, commercial customs, chain of custody	Whether the holder automatically becomes the rights holder should be confirmed case by case.
Separate Assignment Document	Assigns the benefits on the policy by an independent document	Allows detailed description of assignment target, date, and conditions	Relevant policy number, incidents, scope of claims	Ensure clear linkage with the original policy document.
Delivery of Full Set of Shipping Documents	Simultaneous delivery of B/L, Invoice, insurance policy, etc.	Sometimes used in CIF or L/C transactions	Valid endorsement or assignment agreement on the insurance policy	Simply handing over documents together does not necessarily establish policy assignment.
Electronic Assignment Record	Records rights transfer electronically within a system	Issues arise in transactions not using paper policies	Contract terms, system rules, applicable law	Whether this corresponds to customary methods under the MIA 1906 should be confirmed individually.

Practical Points When Reviewing Endorsement Wording

Item to Check	Details to Confirm	Examples of Issues	Practical Response
Endorser	Whether the person can transfer rights on the policy	Signature by an unauthorized staff member	Verify company authority and signing authority
Endorsee	Whether the name and legal entity are accurate	Errors such as bank branch name or company name misspelled	Use the official name
Subject of Transfer	Whether it concerns the entire policy, specific cargo, or claim rights	Unclear subject among multiple cargo items	Specify policy number, invoice, and B/L
Date of Transfer	Relationship with date of incident and transfer date of insurable interest	Endorsement without a date	Record signing date and delivery date
Intent to Transfer	Whether there is clear intent to transfer the benefits under the policy	Only acknowledgement of receipt or signature for bank submission	State the purpose of transfer explicitly
Delivery of Policy	To whom the policy was delivered after endorsement	Endorsed policy retained by the endorser	Maintain delivery records
Prohibition of Transfer	Whether the policy prohibits transfer or requires approval conditions	Failure to obtain required insurer approval	Confirm with the insurer in advance

Section 51 of MIA 1906 and Restrictions on Transfer After Loss of Insurable Interest

Section 51 of the Marine Insurance Act 1906 (MIA 1906) restricts the transfer of insurance policies made by the insured after they have parted with or lost their interest in the insured subject matter.

If there is no express or implied agreement to transfer the policy either before the insured loses their interest or at the time of losing it, any subsequent transfer of the policy will have no effect.

This provision aims to prevent a party who has already lost the economic relationship with the cargo from subsequently transferring only the policy to a third party in a way that would create an insurance interest under the contract.

Conversely, if it can be confirmed that the transfer of the policy coincides with the transfer of interest in the cargo, and there is an agreement based on the sales contract, letter of credit conditions, or trade practice to transfer the policy as well, the application of this section may differ even if the actual endorsement or delivery occurs later.

Whether there is an express or implied agreement is confirmed not only by the contract documents but also by Incoterms, document delivery conditions, L/C terms, communications between the parties, and past transactional practices.

Chronological Example of Insurable Interest, B/L, and Policy Endorsement

Date & Time	Event	Legal and Practical Significance	Supporting Documents
July 1, 9:00 AM	The seller arranges marine cargo insurance in the seller's name	The seller becomes the initial holder of rights on the policy	Insurance policy, insurance placement request
July 2, 3:00 PM	Cargo is loaded onto the vessel	Risk of loss may transfer to the buyer under the sales contract	Sales contract, B/L, shipping records
Before July 2, 3:00 PM	An agreement is reached to transfer the policy to the buyer along with shipping documents	Agreement may occur before or simultaneously with the transfer of risk	Sales contract, L/C, emails
July 3, 10:00 AM	The seller endorses the insurance policy	Acts as a concrete implementation of the prior transfer agreement	Endorsed policy
July 4, 11:00 AM	Policy is delivered to the bank or buyer	Evidence of transfer of interests under the policy	Document delivery records
July 6	Cargo is damaged during transport	Confirms insurable interest and the policyholder’s rights at the time of the accident	Accident report, sales documents

In this example, even if the actual endorsement occurs the day after the risk transfer date, whether an agreement to transfer the policy before or simultaneously with risk transfer was established is the critical issue.

Conversely, if the risk has transferred to the buyer but no agreement to transfer the policy existed, and the policy is only transferred to the buyer after the accident is known, the restrictions under Section 51 could become a problem.

Reasons Why Transfers After Damage Occurrence Are Treated Separately

Section 51 restricts cases where a person who has lost the insured interest subsequently transfers only the policy.

However, the same Section provides that transfers of the policy after the occurrence of damage are not affected.

At the time the insured event occurs, the person who held the insured interest at that time may acquire a claim under the insurance contract to the extent that the payment conditions are met.

Transfers following the occurrence of damage do not transfer the insured interest related to future cargo risks, but rather transfer contractual claims arising from the loss already incurred.

Therefore, there is a legal distinction between a post-event transfer of the policy by someone who lost the insured interest before the damage and a transfer of claims after the event by someone who held the insured interest at the time of the loss.

Nevertheless, even in transfers after damage occurrence, any exclusions, warranties, burden of proof requirements, or other issues attached to the original claim will be inherited by the transferee.

Distinguishing Transfer of Cargo Rights from Assignment of the Insurance Policy

Transferred Right / Status	Main Basis	Typical Documents	Relation to Assignment of Insurance Policy	Points to Note
Cargo Ownership	Sales Contract and Applicable Law	Sales Contract, Invoice	Ownership transfer alone does not automatically assign the policy	Ownership and risk responsibility do not necessarily transfer simultaneously.
Risk Responsibility	Sales Contract, Incoterms, etc.	Sales Contract, Purchase Order	Affects insurable interest location but separate from policy assignment	Actual contract terms should be confirmed.
Right to Claim Delivery of Cargo Under the B/L	Transport Contract and B/L Transfer	Original B/L, Endorsement	B/L transfer alone does not transfer the insurance policy	Separate assignment procedures for the insurance policy may be required.
Interest on the Insurance Policy	Endorsement or Other Assignment of the Insurance Policy	Insurance Policy, Assignment Certificate	Transfers claim rights under the insurance contract	Confirm insurable interest and Section 51.
Designation of Insurance Claim Payee	Loss Payee Clause, etc.	Insurance Policy, Special Conditions	Payee designation does not necessarily equate to assignment of the whole policy	Distinguish the claimant from the payment recipient.
Security Interest	Loan Contract and Security Setting	L/C, Loan Contract, Security Documents	Bank holding the policy may not be a full assignee	Confirm whether it is for collateral purposes or actual rights transfer.

Assignment of Insurance Policies in CIF Transactions

In CIF transactions, it is common for the seller to arrange marine cargo insurance and provide the insurance policy or certificate to the buyer.

After the seller concludes the insurance contract and the risk of the cargo transfers to the buyer, it is necessary to properly assign the benefits under the policy so that the buyer can claim insurance proceeds in the event of an incident.

Therefore, in CIF transactions, it is important not only that the insurance is arranged in the seller’s name but also to confirm the assignability of the insurance policy, endorsements, delivery of the original policy or electronic record, and the buyer’s insurable interest.

Even if the B/L is assigned to the buyer or a bank, this does not necessarily mean that the assignment of the insurance policy has been automatically completed.

Points to Confirm in CIF and Letter of Credit Transactions

Confirmation Item	What to Confirm in CIF Transactions	What to Confirm in Letter of Credit Transactions	Impact if There Are Issues	Practical Measures
Policy Name	Whether it is in the seller's name, buyer's name, or a blanket name	Whether it matches the name required by the L/C	Document discrepancies or disputes over claim rights	Confirm the name before issuance
Transferability	Whether transfer is prohibited or subject to approval conditions	Whether a transferable policy is required	Rights cannot be transferred to the buyer or bank	Check the policy conditions
Endorsement	Is a named endorsement or blank endorsement to the buyer required?	Whether the endorsement complies with L/C conditions	Discrepancies or issues with entitlement to claim	Confirm the official name and signature authority
Risk Transfer	Who bears the financial loss in case of an accident	Consistency with sale documents	Absence of insurable interest	Verify the sales contract and shipment date
B/L	Shipper, Consignee, and endorsements	Compliance with L/C conditions	Separation of cargo delivery and insurance rights	Check B/L and insurance policy separately
Insurance Amount and Currency	Whether it matches the sale value and contract terms	Whether it matches the percentage and currency specified by L/C	Document rejection or coverage shortfall	Cross-check with Invoice and L/C
Coverage Conditions	Whether the ICC required by the sales contract is used	Whether it matches the conditions stated in the L/C	Possible exclusion of accidents despite document compliance	Substantially verify the Clause content
Policy Issue Date	Relation to risk transfer and timing before/after accidents	Whether it meets presentation deadlines	Issues under Section 51 or document deadlines	Record endorsement date and issue date

Status of Banks in Letter of Credit Transactions

In letter of credit (L/C) transactions, banks may receive marine insurance policies or certificates as part of the shipping documents.

The mere fact that the bank receives or holds these documents does not necessarily mean that the bank has acquired all the benefits under the marine insurance policy.

It should be confirmed whether the bank is temporarily holding the policy for document examination, holding it as a secured party, or has acquired the benefits under the policy by a nominative endorsement or blank endorsement.

Whether the documents comply with the L/C terms is a separate issue from whether the insurer is liable to pay for the loss or damage.

At the time of an insurance claim, the endorsement of the insurance policy, the insured interest, the terms of any security, the cause of loss, and the rights relationship between the bank and the buyer should be verified.

Practical Flow of Policy Assignment

1. Check the Insurance Policy
   Confirm the insured party, policy number, insured cargo, transportation segment, applicable clauses, and any non-transferable provisions.
2. Confirm the Purpose of Assignment
   Distinguish whether it is for sale, L/C settlement, collateral setting, or post-accident claim rights transfer.
3. Verify Before and After Incident
   Chronologically arrange the incident date, assignment agreement date, endorsement date, and policy delivery date.
4. Confirm the Timing of Transfer of Insurable Interest
   Check the risk allocation under the sales contract and the actual economic loss bearer.
5. Confirm Application of Section 51
   Verify whether the assignment agreement occurred before or simultaneously with the loss of interest.
6. Confirm Method of Assignment
   Check whether it involves named endorsement, blank endorsement, assignment deed, or other methods.
7. Verify Assignment Authority
   Confirm whether the assignor and signatories are authorized to transfer the policy.
8. Confirm Substantial Interest on the Policy
   Verify the intent to transfer claim rights, not merely formal document delivery.
9. Cross-check B/L and Sales Documents
   Separate and organize the transfer of cargo rights and the transfer of rights on the insurance policy.
10. Check Insurer’s Defenses
    Review exclusions, insurance period, warranties, disclosure/representation, and covered risks.
11. Notify the Insurer
    If required by contract or trade practice, notify the insurer of the assignment and change of claimant.
12. Preserve Evidence
    Retain endorsed policies, assignment deeds, emails, delivery records, and system logs.

Scenario for Application of the System 1: Transfer Before Accident in CIF Transactions

Assume a Japanese seller exports goods under CIF terms and arranges marine cargo insurance in the seller’s name.

The sales contract specifies that risk passes to the buyer upon shipment on board the vessel, and the seller is to transfer the insurance policy to the buyer along with the shipping documents.

The seller endorses the insurance policy to the buyer and delivers the original policy document before the accident occurs. The cargo is then damaged during transit.

If the buyer had an insurable interest in the cargo at the time of the accident and has effectively acquired the substantive interest in the policy documented by the endorsement, the buyer may be able to claim the insurance proceeds in their own name.

Confirm the sales contract, the timing of risk transfer, the endorsement, delivery of the policy, and the date of the accident.

Application Scenario 2: When the Insurance Policy is Transferred for the First Time After Risk Has Passed

The risk passed from the seller to the buyer at shipment on July 2, but assume there was no agreement regarding the transfer of the insurance policy at that time.

While the cargo is sailing without incident, the seller retains the policy and on July 5 agrees to transfer the policy to the buyer, endorsing it for the first time then.

If the seller relinquished the insurable interest in the cargo on July 2, and there was no express or implied agreement to transfer the policy before or at that time, the transfer on July 5 may not be effective under Section 51.

It cannot be assumed simply because the transaction is CIF that an agreement to transfer the policy necessarily exists.

The sales contract, Letter of Credit conditions, past trade practice, and communications between the parties should be reviewed.

Application Scenario 3: Assignment of Insurance Claims After an Accident

Assume a fire occurs while the seller still holds an insurable interest in the cargo, resulting in a total loss of the cargo.

After the accident, the seller assigned the marine insurance policy and the insurance claim rights related to the accident to the trading company for settlement purposes.

The restrictions under Section 51 regarding the loss of insurable interest do not affect the transfer of the policy after the loss has occurred.

If the contractual claim rights held by the seller at the time of the accident have been validly transferred to the trading company, the trading company may be able to claim in its own name.

However, it should separately be confirmed whether the fire is a covered peril, whether the loss occurred within the insurance period, whether there are any exclusions, and whether the amount of loss has been substantiated.

Scenario 4 for Application of the System: Asserting Warranty Breach Against the Assignee

Suppose the transportation contract required the cargo to be stowed under deck, but the insured loaded it on deck without the insurer's approval, and subsequently assigned the insurance policy to the buyer.

The cargo was lost overboard on deck, and the buyer made a claim as the assignee.

Even if the transfer of the policy is valid, the breach of warranty or any special conditions related to the on-deck stowage in the original insurance contract does not disappear.

The insurer may be able to assert against the buyer the contractual defenses that could have been raised against the original insured.

It is necessary to verify the applicable conditions, booking, B/L, insurer approval, and cause of loss.

Scenario 5 of System Application: When the Bank Holds a Blank-Endorsed Policy

In a CIF transaction, suppose the seller has placed a blank endorsement on the insurance policy and presented it to the bank as part of the L/C documents.

During transit, a cargo incident occurs, raising the question of whether the bank, buyer, or seller is entitled to claim the insurance proceeds.

The mere fact that the bank physically holds the policy does not necessarily mean that the bank is the ultimate claimant.

It is necessary to confirm the effect of the blank endorsement, the bank’s purpose in holding the policy, any security interests, the status of document delivery to the buyer, and the payment settlement situation.

Additionally, it is important to clarify whether the policy holder and the insured interest holder at the time of the incident are the same.

Application Scenario 6: Only the B/L Is Transferred

Assume the seller endorsed and transferred the order B/L to the buyer, but the marine insurance policy remained in the seller’s name.

Subsequently, the cargo was damaged during transit.

The transfer of the B/L relates to the transfer of rights to claim delivery of the cargo and other rights under the transport documents, but this does not necessarily mean the rights under the marine insurance policy also transfer automatically.

Even if the buyer holds an insurable interest in the cargo, if they have not acquired rights under the insurance policy, there may be issues when claiming insurance proceeds in their own name.

It should be confirmed whether the sales contract included agreement on transferring the insurance policy and whether a valid endorsement or transfer procedure was subsequently completed.

Application Scenario 7: When a Non-Assignment Clause Is Included

Suppose the marine insurance policy includes a special condition prohibiting the assignment of the policy without the insurer’s prior written consent.

The insured assigns the policy to a third party without notifying the insurer, and subsequently, the assignee files a claim for a loss under the policy.

Section 50 of the Marine Insurance Act 1906 (MIA1906) treats policies expressly prohibiting assignment as an exception to the general rule allowing assignment.

Therefore, the validity of the assignment without the insurer’s prior consent becomes a contractual issue.

The exact wording of the non-assignment clause, whether consent is required, communications with the insurer, and the timing of the assignment should be confirmed.

Common Misconceptions

Misconception	Actual Understanding	Practical Considerations
All marine insurance policies are freely transferable	There may be explicit prohibitions or approval conditions on transfer.	Check the policy and any special conditions.
Once ownership of the cargo transfers, the policy automatically transfers	Transfer of cargo rights and transfer of the insurance policy are separate procedures.	Confirm endorsements or transfer agreements.
If risk transfers, the buyer can always claim compensation	It must be confirmed whether the buyer has also acquired the rights under the policy.	Separate insurable interest from policy transfer.
Receiving the B/L means the insurance policy has also been transferred	Rights under the B/L and rights under the insurance contract are distinct.	Verify actual transfer of the insurance policy itself.
Holding the policy guarantees receipt of compensation	Substantial benefits under the policy, insurable interest, and coverage conditions are required.	Do not judge solely by formal possession.
The insurer’s defenses do not apply to a bona fide transferee	Defenses based on the original contract generally apply to the transferee as well.	Check disclosures, conditions, and exemptions at policy inception.
The policy cannot be transferred after a loss occurs	Section 50 of the MIA 1906 permits transfer even after loss.	Confirm insurable interest and claim rights at time of loss.
Transfer after loss guarantees payment of insurance money	Coverage validity, exemptions, and damage assessments are still required post-transfer.	Do not confuse confirmed claims with unconfirmed ones.
The policy can be transferred at any time after loss of insurable interest	Without prior or concurrent transfer agreement, Section 51 may invalidate the transfer.	Verify dates of interest transfer and agreement.
Endorsements made after transfer of interest are always invalid	Whether a transfer agreement existed before or simultaneously with interest transfer is also important.	Check sales contracts and emails.
Possession of a blank endorsement automatically makes the holder the rights holder	Confirm policy format, delivery, trading customs, and intention to transfer rights.	Do not conclude based on possession alone.
If a bank holds the insurance policy, the bank automatically becomes the claimant	Distinguish document examination, collateral retention, and full policy transfer.	Confirm L/C and financing agreements.
If documents comply with the L/C, insurance money will also be paid	Document compliance and coverage under the insurance contract are separate issues.	Check cause of loss, insurance period, and exclusions.

Summary

Section 50 of the Marine Insurance Act 1906 (MIA1906) establishes that unless an explicit prohibition on assignment is stated on the marine insurance policy, the policy may be assigned.

A marine insurance policy can be assigned either before or after the occurrence of loss.

When the substantial interest under the policy is effectively transferred on the policy, the assignee may make claims under the insurance contract in their own name.

However, the right of the assignee to claim in their own name is separate from whether the conditions for payment of the insurance money are met.

The insurer, in principle, may assert against the assignee any defenses, exclusions, insurance periods, warranties, Fair Presentation of the Risk, insurable interest, or other defenses that could have been raised under the original insurance contract.

Section 50 of MIA1906 recognizes assignment by endorsement on the policy or other customary methods.

In practice, named endorsements, blank endorsements, separate assignment instruments, or delivery of the policy may be used, but the specific effect depends on the policy form, wording of assignment, authority to sign, trade practices, and governing law.

Section 51 of MIA1906 provides that an assignment made after the insured has relinquished or lost the interest in the insured subject matter, without prior or simultaneous agreement to assign the policy, is void.

Even if an actual endorsement or delivery occurs after the interest transfer, it is necessary to confirm whether an express or implied agreement to assign the policy prior to or simultaneously with that transfer existed.

The restriction under Section 51 does not apply to assignments of the policy after the occurrence of loss.

Assignments after loss transfer the interest under the policy, including potential insurance claim rights arising to the person who held the insurable interest at the time of the loss.

However, even if assigned post-loss, any coverage issues and insurer defenses existing in the original claim rights do not disappear.

Ownership of the cargo, risk transfer, cargo delivery claims under the Bill of Lading, and rights under the marine insurance policy represent distinct legal relationships.

Assignment of the Bill of Lading to the buyer or bank does not automatically transfer the interest under the marine insurance policy.

In CIF transactions, the timing of risk transfer, agreement to assign the insurance policy, endorsement, delivery of the policy, and buyer's insurable interest should be considered together.

In letter of credit transactions, it is important to distinguish between the bank’s acceptance of documents, holding the policy as collateral, and transfer of the substantial interest under the policy.

When considering assignment of an insurance policy, it is essential to separately clarify any prohibition clauses, timing before or after loss, date of insurable interest transfer, date of assignment agreement, endorsement date, delivery date, assignor’s authority, assignee’s status, and insurer’s defenses.

If disputes arise regarding the effectiveness of assignment, or the ownership of insurable interest or insurance claim rights, retain the insurance policy, sales contracts, Bill of Lading, invoices, letters of credit, endorsements, assignment instruments, loss documents, and correspondence, and seek confirmation from the insurer, insurance agent, or specialists familiar with the Marine Insurance Act 1906.
