Marine insurance serves as a lifeline for global trade by providing financial protection against various risks at sea. But what makes a marine insurance contract valid and trustworthy? The answer lies in the principles of marine insurance. These fundamental rules ensure that every party involved acts fairly, transparently, and responsibly.

Whether you’re an exporter, importer, shipowner, or insurance professional, understanding the principles of marine insurance is crucial for making informed decisions and securing rightful claims.

What Are the Principles of Marine Insurance?

The principles of marine insurance are legal and ethical guidelines that form the core of every marine insurance contract. These principles are designed to create trust, clarity, and balance between insurers and insured parties. Ignoring these principles can result in disputes, claim rejection, or even cancellation of the policy.

Let’s break down each one in detail.

1. Principle of Utmost Good Faith (Uberrimae Fidei)

Marine insurance is built on complete honesty. Both the insurer and the insured must disclose all material facts related to the risk.

Insured’s duty: Share details about cargo type, ship condition, known risks, and previous losses.

Insurer’s duty: Clarify terms, conditions, and exclusions upfront.

📌 Violation of this principle can make the contract void.

2. Principle of Insurable Interest

The insured must have a financial interest in the subject matter of insurance. In simple terms, you must stand to lose if the cargo or ship is damaged.

You can’t insure someone else’s goods unless you are legally responsible for them.

Insurable interest must exist at the time of loss, not necessarily when the policy is taken.

3. Principle of Indemnity

This principle ensures that the insured is compensated only to the extent of actual loss.

No profit is allowed from a claim.

The purpose is to restore the financial position before the loss occurred.

📊 According to a marine claim analysis in 2023, around 14% of claims were reduced due to over-valuation, highlighting the importance of this principle.

4. Principle of Contribution

If the insured has taken multiple policies for the same cargo or risk, they cannot claim the full amount from all policies.

The claim will be proportionately shared between the insurers.

This prevents unjust enrichment.

5. Principle of Subrogation

After compensating the insured, the insurer gets the legal right to recover the loss amount from third parties responsible for the damage.

For example, if a negligent port authority caused damage, the insurer can sue them after settling your claim.

6. Principle of Proximate Cause

Only losses that occur directly due to the insured risks will be compensated.

If the loss results from multiple causes, the nearest or dominant cause is considered.

For example, if goods are damaged due to a fire (covered), but the fire was caused by illegal acts (not covered), the claim may be denied.

7. Principle of Loss Minimization

The insured must take reasonable steps to prevent or minimize loss even after taking insurance.

Failure to do so can lead to reduced compensation or rejection.

Example: If cargo is about to be damaged by water, the insured should try to move it to safety.

Why Are the Principles of Marine Insurance Important?

These principles:

Establish trust between the insurer and insured.

Ensure fairness and prevent fraud.

Make claim settlements faster and legally sound.

Help avoid unnecessary disputes.

📈 According to the International Union of Marine Insurance (IUMI), disputes over policy interpretation have dropped by 9% in regions where policyholders understand these principles well.
