6 Principles of Marine Insurance Decoded

The principles of marine insurance are the core legal and ethical norms that govern marine insurance contracts and related claims. These core principles are there to ensure or instil trust, fairness, and transparency between a policyholder or insured and the insurance company.

The 6 core principles of marine insurance include utmost good faith, indemnity, insurable interest, proximate cause, contribution, and subrogation. Each principle helps protect against disputes, delays, or unexpected liabilities while goods are in transit.

This blog explains these core principles in detail, and if you're looking for marine insurance, you'll understand their importance.

What are the 6 Core Principles of Marine Insurance?

If you run a business that ships goods by sea, you may need marine insurance. The following are the core principles of this sort of insurance that you must be aware of, as these are the rules which govern such an insurance product:

Utmost Good Faith

When you sign a marine insurance contract, this principle requires you and the insurer to act with utmost honesty and is the first principle of marine insurance. If you fail to disclose important facts such as the nature of your cargo, the route, or the condition of the vessel, your insurer may deny your claim if you raise it.

Suppose you are an exporter sending electronics by sea. If you do not mention that the route goes through a piracy-prone zone, that omission breaches this principle. Breaches can take four forms: concealment, non-disclosure, fraudulent misrepresentation, and innocent misrepresentation. Your insurer must share policy details without fail.

Indemnity Principle

The 2nd essential part of the principle of marine insurance is indemnity. This means that you will not gain any profit by making a claim. According to this, you will be put back (as far as possible) into the financial position you were in before the loss.

Here, you may wonder why the principle of indemnity does not allow for any gain or loss? You must note that this principle aims to prevent a marine insurance policy from becoming a source of unethical gains. It also reduces the potential for fraudulent claims, as it eliminates any incentive to exaggerate losses.

Insurable Interest

An insurable interest is a principle of marine insurance that requires a business to have a legal or financial stake in the goods being insured at the time of loss. In simple words, an insured party must lose money if the goods in shipment get stolen, missing or damaged.

An insurable interest may not need to exist when you purchase a marine insurance policy. However, it must exist when the loss occurs. For example, a merchant who ships cargo and insures it cannot make a valid claim if they do not own the cargo at the time of the damage. It ensures that policyholders do not use marine insurance for speculation.

Proximate Cause

The next fundamental principle of marine insurance you must be aware of is the proximate cause. It refers to the nearest or most direct cause of loss covered by the policy. If the policy covers that cause, the insurer pays. But if it does not, the insurer may reject the claim. For instance, Mr Raichand's cargo was damaged during rough seas (a covered peril).

However, the damage occurred due to inadequate packing (an exclusion). The proximate cause may be considered the omission of packing, which could lead to a claim denial. To avoid this, it is important to read the policy wording and brochure of your marine insurance policy thoroughly so you can manage packaging and transit risks accordingly.

Contribution

Another less-discussed yet vital element of the basic principles of marine insurance is contribution. One cargo or transportation may carry a risk which is covered by different insurance policies. In this scenario, those insurers share the loss proportionately.

Let us understand it with an example. You insured cargo for ₹50 lakhs with two policies: one for ₹30 lakhs, another for ₹20 lakhs. If a loss of ₹10 lakhs happens, the two insurers will contribute proportionately (30/50 and 20/50 shares).

Subrogation Principle

This is the final one amongst the principles of marine insurance involves subrogation. Once the insurer pays you for a loss, you cannot keep using the damaged goods for your own benefit. This principle is co-dependent on the indemnity principle.

For instance, your cargo was damaged due to the negligence of a port operator. After your marine insurance claim is settled, the insurer may pursue that operator for recovery. You cannot use your cargo further.

What is the Interrelationship Between the Principles of Marine Insurance?

These 6 principles of marine insurance are not stand-alone norms, and to instil transparency, fairness, and legal clarity, they work together. For a further understanding of these principles, you must understand how they interconnect and here is a detailed description:

Utmost Good Faith and Insurable Interest

While these two are applied in marine insurance, they both ensure honest disclosure and valid financial stakes. It is important, as an insurer depends on such (e.g. the disclosures) for risk assessment and to offer terms that are fair to an insured party. Thus, these two help establish a foundation of marine and principal of insurance contracts for cargo.

Indemnity With Contribution

You have noted that indemnity prevents an insured party from profiting through marine insurance as they incur a loss. Contribution is there to ensure that when there are multiple policies in place, insurers must share liabilities in proportion.

For instance, if a certain cargo is covered under two different policies, the insured party cannot make a claim for the full amount from all the policies. Contribution here divides the respective payout proportionately, maintaining fairness.

Proximate Clause With Subrogation

These two principles of marine insurance work in tandem, where the proximate clause determines whether a loss has been covered under a marine insurance policy. Subrogation allows an insurer to recover the loss amount from a third party involved in or responsible for the loss.

For understanding, suppose a third party causes a loss to the insured. Upon paying the claim to that insured, the insurance provider may sue that party in order to recover that loss.

Combined Influence of Core Principles of Marine Insurance

All these principles work with the aim of reducing the chances of making fraudulent claims. Together they ensure that both parties (insurer and the insured) act with responsibility. Thus, these principles help marine insurance as a product be efficient, enforceable, and ethically stronger, as they support each other.
