Marine Insurance Law Vietnam: Disclosure, Good Faith and Claims Defences

Updated: 14 October 2026 · IVLF Advisors

A marine claim is rarely lost because the casualty was uninsured. It is lost because of what the proposal form left out, a clause read differently by the insurer and the assured, or a rule from a different statute than the one the broker assumed. Marine insurance law Vietnam participants deal with is built from several layers: the Maritime Code, the general insurance statute, the contract wording and, in most placements, English-law market practice.

For shipowners, cargo owners, banks and insurers, the hidden risk is a gap between the layer the parties believe governs and the layer a Vietnamese court or arbitral tribunal will apply. This article maps those layers, explains how disclosure and utmost good faith operate in practice, shows the main claims defences, and sets out checks to run before signing a policy or paying a premium.

Marine Insurance Law Vietnam: The Legal Layers

No single instrument answers every question under marine insurance law Vietnam clients ask about. A practical review separates the sources, then asks which one governs the point in dispute.

Marine insurance law Vietnam: the statutory sources

The first source is the Vietnam Maritime Code 2015 (Law No. 95/2015/QH13, effective 1 July 2017, consolidated as 101/VBHN-VPQH of 26 August 2025), which contains a chapter on marine insurance contracts. Which of its provisions apply to a given policy, and how they relate to the general insurance statute, should be confirmed from the consolidated text.

The second source is the general insurance statute discussed below. The third is the policy itself, usually based on market wording. The fourth is the governing law and forum clause, which may point to English law and London arbitration or to Vietnam. Marine insurance law Vietnam practitioners must therefore read the contract first and the statute second, then test each against mandatory local rules.

English-law doctrine in the background

For readers who advise on marine insurance law Vietnam cross-border placements, the distinction between English-law practice and local mandatory rules is the single most common source of error.

Many marine policies are written on wording derived from English-law market practice, such as the Institute Cargo Clauses 2009, and incorporate English principles. The English Marine Insurance Act 1906 and the Insurance Act 2015 are English statutes, not Vietnamese law. They matter in Vietnam only where the policy chooses English law or where a Vietnamese tribunal treats the clauses as drafted in that tradition. Always label which system is being applied.

Layer	What it governs	Typical problem	Risk
Maritime Code chapter on insurance	Marine insurance contract rules for Vietnamese-law contracts	Assumed to be displaced by a general statute without checking	Medium
Law on Insurance Business	Insurer licensing, contract conduct, claims handling	Mandatory consumer-style protections not anticipated	High
Policy wording	Cover, exclusions, conditions, claims procedure	Ambiguous typed clauses versus printed terms	High
Governing law and forum clause	Which rules and tribunal decide the dispute	Foreign law clause that local mandatory rules or enforcement override	High

Law on Insurance Business 2022 and Law 139/2025

The Law on Insurance Business 2022 (Law No. 08/2022/QH15, passed 16 June 2022, effective 1 January 2023) is the general framework for insurance undertakings in Vietnam. Decree 46/2023/NĐ-CP, effective 1 July 2023, guides its implementation, and was in turn amended by Decree 97/2026/NĐ-CP, reported in April 2026.

The statute was amended by Law 139/2025/QH15 of 10 December 2025, and a consolidated text, 31/VBHN-VPQH, was published in 2026. Anyone who relies on an older commentary should check the current consolidated text before advising. Specific amended provisions and their effect on marine business are not stated here.

How the general statute may interact with maritime rules

The interaction matters because the statute regulates the insurer, while the Maritime Code regulates the maritime venture. A policy can be perfectly drafted for one and non-compliant with the other. Banks financing a vessel should require evidence that the cover is valid under both the policy law and the local regime before accepting it as security.

Three questions deserve a written answer in any matter involving Vietnamese law:

• whether the Maritime Code chapter or the general statute governs the specific issue, for example disclosure, premium, notice or claim payment deadlines;
• whether a mandatory local rule applies even if the policy is subject to a foreign governing law;
• whether the insurer is licensed to write the risk in Vietnam, and how cross-border placement is treated.

Official texts and amendments are published on the government legal portal at vanban.chinhphu.vn. For a policy under review, ask counsel to match the current consolidated text against the clause list.

Utmost Good Faith and the Disclosure Duty

Insurance is a contract in which the insurer relies on information it cannot easily verify. For that reason, marine insurance has long been treated as a contract of utmost good faith, a principle recognised in international and English-law practice and reflected in most legal systems in some form.

What utmost good faith means in practice

Utmost good faith, as understood in English-law market practice, requires the parties to deal openly. The assured must not misrepresent or hide facts that would influence a prudent insurer, and the insurer must handle the claim fairly and not exploit technical points. It is both a pre-contract and a claims-stage duty.

How far Vietnamese law mirrors this principle, and what remedy follows a breach, must be checked against the applicable chapter of the Maritime Code and the Law on Insurance Business 2022.

Insurer duties and the claims stage

Good faith also binds the insurer. It should investigate promptly, state its reasons in writing, and avoid raising technical objections it has not previously signalled. An assured who documents each request and response builds a record that supports a complaint to a tribunal, and demonstrates its own cooperation, which most policies make a condition of payment.

Scope of the disclosure duty

The disclosure duty requires the assured to tell the insurer what a prudent insurer would want to know when deciding whether to accept the risk and on what terms. Under English-law doctrine, historically the duty extended to every material circumstance known to the assured. The Insurance Act 2015 in England has since replaced the old rule with a duty of fair presentation of the risk. Both are English-law concepts and should not be assumed to apply under a Vietnamese-law policy.

In practical terms, owners and cargo interests should treat the following as presumptively material and disclose them accurately:

• previous casualties, claims history and port state detentions;
• changes of class, flag, manager, charterer or trading pattern;
• unusual cargo, voyage routes, sanctions exposure and transhipment arrangements;
• ownership, financing and loss payee arrangements;
• known defects, outstanding class recommendations and surveys.

Takeaway: a disclosure checklist signed by the operator, with supporting documents, is the best defence against an allegation of non-disclosure. Keep a dated record of what was sent to the broker and when.

Insurance Contract Interpretation and Policy Wording

Disputes over meaning decide more claims than disputes over facts. Insurance contract interpretation follows the governing law, but several principles recur across systems and are useful in negotiating wording.

Principles that usually apply

• The wording is read as a whole, giving effect to the commercial purpose of the cover.
• Specific, typed or negotiated clauses generally prevail over general printed terms.
• Ambiguity in standard-form wording is often resolved against the party who drafted it, usually the insurer, a doctrine known in English-law practice as contra proferentem.
• Exclusions are read narrowly, and the insurer bears the burden of bringing a loss within one.
• Defined terms, such as seaworthiness, war, strike or inherent vice, should be read with their definitions and cannot be assumed to have ordinary meaning.

Whether a Vietnamese court or tribunal will apply the same techniques, and how it treats foreign standard clauses, depends on the governing law and practice. The safest approach is to draft so that the interpretation question never arises.

Drafting points that reduce interpretation risk

Clear drafting is the cheapest form of protection. A single ambiguous sentence in an extension clause can decide a very large claim, so lawyers should review the wording before inception, not after the loss.

• State the governing law and forum in the policy, and confirm they are enforceable where assets and the insured vessel are.
• Replace undefined terms with definitions or attach the incorporated clause text.
• Ensure the proposal and any warranty statements are consistent with the operating reality.
• Record agreed deviations as endorsements, not emails.
• Obtain written confirmation of cover for each stage of the voyage or period.

Claims Defences Insurers Raise

Insurers do not usually decline a claim without a documented reason. Understanding the typical defences helps the assured prepare the file before presenting the claim.

Common defences and responses

Issue	Legal position	Commercial impact	Risk	Mitigation
Non-disclosure or misrepresentation	Remedy depends on governing law and materiality	Avoidance or reduction of the entire claim	Fatal	Signed disclosure file; verify facts before submission
Breach of warranty or condition	Effect varies by law and wording; some systems suspend rather than void cover	Claim declined or delayed	High	Compliance calendar for class, trading and survey conditions
Unseaworthiness or unfitness	Often tied to the assured’s knowledge or privity	Exclusion argument against hull and cargo claims	High	Maintain class, ISM records and cargo-worthiness evidence
Late notice or non-cooperation	Policy condition; prejudice may be required	Dispute over quantum and evidence	Medium	Notify at once; preserve evidence and records
Fraudulent or inflated claim	Serious consequences under most systems	Loss of the whole claim and potential liability	Fatal	Independent verification of quantum before submission
Excluded peril or cause	Burden and standard of proof set by law and wording	Coverage denied for the loss	High	Map the cause of loss to the policy at first notice

Evidence discipline: in most disputes the assured carries the burden of showing a loss within cover, and the insurer carries the burden of showing an exclusion. Photographs, surveyor reports, logbooks, cargo documents and dated correspondence decide those burdens. For wider context on how shipping contracts allocate risk, see political risk insurance (MIGA and PRI).

Insurers’ rights after payment, such as subrogation against a responsible third party, can also affect the assured’s conduct. Do not release a carrier, terminal or charterer from liability without checking the policy, because that can prejudice the insurer’s recovery and the claim itself. The International Union of Marine Insurance publishes market information and clause material at iumi.com, which helps in understanding standard wording.

Practical Playbook and Hypothetical Scenario

The following steps apply whether the policy is hull, cargo or liability. Deadlines are items to check against your policy and the applicable law.

1. Before placement: assemble a disclosure file, signed by the operator, covering casualty history, class, trading and cargo.
2. At placement: confirm governing law, forum, insurer licensing and the clause set in writing; reconcile with financing documents and loss payee terms.
3. During the policy: notify material changes promptly; keep a compliance calendar for warranties and conditions.
4. After a casualty: notify the insurer, preserve evidence, avoid releasing third parties, and do not admit liability.
5. On claim: submit a documented claim, track insurer queries, and calendar limitation and time bars.

Hypothetical scenario

Hypothetical scenario: a Vietnamese importer insures a shipment under a market cargo policy. Assumptions: the proposal described the goods as new, but the exporter had told the importer that the batch included refurbished items; the policy is subject to English law with arbitration abroad; the cargo is damaged by seawater ingress; no fraud is alleged.

The insurer may argue that the misdescription was material and seek to avoid or reduce the claim. The importer’s best position rests on the evidence file: what was said to the broker, the exporter’s documents, whether the point affected the risk, and how the governing law treats an innocent misstatement. Had the importer kept a signed pre-placement declaration and sent the exporter’s invoice with it, the discussion would turn on materiality rather than concealment. The outcome is not predictable on these assumptions alone, which is why the file matters.

Conclusion and Next Step

Marine insurance law Vietnam parties face is a stack of rules, not one. Disclosure, wording and governing law decide outcomes more often than the casualty does.

Practical next action: before the next renewal, assemble the disclosure file, check the governing law and forum, and have counsel compare the policy against the current consolidated text of the Maritime Code and the Law on Insurance Business 2022 as amended by Law 139/2025. Resolve every point marked for verification before the policy incepts.

Frequently Asked Questions

Does the Maritime Code or the insurance statute govern a marine policy?

It depends on the issue and governing law. Both may be relevant, and the relationship should be confirmed from current consolidated texts.

What is utmost good faith in marine insurance?

It is the principle that both parties deal openly. The assured discloses material facts and the insurer handles claims fairly. Its remedies differ between legal systems.

Can an insurer refuse a claim for non-disclosure?

Possibly, if the undisclosed fact was material and the governing law allows it. Remedies range from avoidance to proportionate reduction, so check your policy and law.

Which law applies to my policy?

The governing law clause, subject to mandatory local rules. Many market policies choose English law. Confirm enforceability where the vessel, cargo or assets are located.

Did the 2025 amendment change marine insurance in Vietnam?

Law 139/2025/QH15 amended the Law on Insurance Business. Its effect on marine contracts should be verified from the consolidated text.
