4.2 Principle of Utmost Good Faith (Uberrima Fides) and Duty of Disclosure

4.2 Principle of Utmost Good Faith (Uberrima Fides) and Duty of Disclosure

Quick Summary: In commercial contracts, common law follows caveat emptor ("let the buyer beware"), requiring no positive duty to volunteer information. Insurance contracts discard this rule in favor of uberrima fides (utmost good faith), which imposes a reciprocal legal duty to disclose all material facts before the contract is concluded. A material fact is any circumstance that would influence the judgment of an objective prudent underwriter in fixing premium or accepting the risk (Carter v Boehm). Breaches through non-disclosure (omissions) or misrepresentation (false statements) render the policy voidable, entitling the insurer to avoid the contract ab initio (from inception).

Caveat Emptor versus Uberrima Fides

Under the general common law of contract, commercial dealings are governed by caveat emptor ("let the buyer beware"). In purchasing commercial machinery, vehicles, or real estate, a seller must not make fraudulent misrepresentations, but is under no positive legal duty to disclose latent defects. The buyer is expected to inspect the subject matter and ask questions.

In insurance contracts, caveat emptor is displaced by the doctrine of uberrima fides (utmost good faith).

Why Insurance Requires Utmost Good Faith

The justification rests on severe information asymmetry:

• The subject matter of insurance—such as the internal wiring of an industrial plant, specialized manufacturing processes, or private medical histories—lies within the exclusive knowledge of the proposer.
• An underwriter in a corporate office cannot physically inspect every internal component or verify unrecorded operational risks without prohibitive costs and delays.
• Insurers must therefore rely on the complete candor and transparency of the proposer.

This principle was established by Lord Mansfield in Carter v Boehm (1766):

"Insurance is a contract upon speculation. The special facts, upon which the contingent chance is to be computed, lie most commonly in the knowledge of the insured only... Good faith forbids either party, by concealing what he privately knows, to draw the other into a bargain from his ignorance of that fact."

The Reciprocal Nature of the Duty

Utmost good faith is strictly reciprocal—it binds both insurer and insured:

• Insured's Duty: The proposer must disclose all material facts and must not misrepresent them, whether or not the insurer asks.
• Insurer's Duty: The SCI study text gives examples. The insurer should tell the insured about a premium discount the insured is entitled to, for example for a good claims record or good preventive measures. It should accept only risks it is registered to accept, so that the contract is enforceable. It must make sure its statements about the cover are true. If the insurer breaches this duty, the insured may avoid the contract.

The Duty of Disclosure and the Prudent Underwriter Test

The duty of disclosure requires the proposer to volunteer, prior to contract conclusion, every material fact within their actual or constructive knowledge.

Definition of a Material Fact

A material fact is legally defined as:

"Any circumstance which would influence the judgment of a prudent insurer in fixing the premium, or determining whether he will take the risk."

The Objective "Prudent Underwriter" Test

Materiality is determined by an objective legal standard:

• It does not depend on what the proposer subjectively thought was important.
• It does not depend on the subjective view of an individual underwriter.
• The legal test asks whether a hypothetical, reasonable, and prudent underwriter in that class of business would consider the fact relevant in evaluating the risk, setting premium rates, or imposing terms.

Categories of Material Facts

1. Physical Hazards: Combustible construction materials (timber vs reinforced concrete); storage of hazardous chemicals or unventilated lithium-ion batteries; aftermarket motor vehicle modifications; history of local flash floods.
2. Moral Hazards: Prior criminal convictions (fraud, theft, arson); adverse claims history across recent years; prior refusal, cancellation, or imposition of special terms by another insurer ("declined risk"); severe corporate insolvency.
3. Special Circumstances: Abnormal commercial contracts waiving subrogation rights or assuming strict third-party indemnities.

Facts That Need NOT Be Disclosed

The law accepts that some facts need not be disclosed unless the insurer asks about them:

1. Facts that lessen the risk, such as smoke detectors, sprinklers, alarms and security fittings.
2. Facts of common knowledge, such as that jewellery is attractive to thieves or that Singapore has heavy monsoon rain.
3. Facts the insurer has waived, for example where a blank space on a completed proposal form is not followed up before the policy is issued.
4. Facts of law, because everyone is presumed to know the law.
5. Facts the insurer knows or ought to know, including facts disclosed in the report of a risk surveyor appointed by the insurer.
6. Facts that a policy term makes unnecessary, such as a matter already covered by a warranty or condition.

Duration and Operation of the Duty of Disclosure

The duty of disclosure follows a defined operational timeline:

1. Pre-Contract Negotiations: Begins when negotiations start (requesting quotes or submitting proposal forms) and ends when the contract is formed (when the insurer accepts the proposal and agrees cover). Any new material facts that arise before acceptance must be disclosed. A policy wording may extend the duty so that it continues throughout the period of insurance.
2. During the Policy Term (Dormant): Under common law, the duty is dormant during the policy term. However, standard policies include an express Material Alteration Clause, requiring the insured to notify the insurer immediately of any material change in risk (e.g., converting a retail store into a commercial kitchen).
3. Policy Renewal (Revival): General insurance is short-term business, usually renewed every 12 months. Each renewal forms a new contract, so the duty of disclosure revives in full. Long-term business such as life insurance is different: the insurer must accept continued premiums, no new contract is formed, and there is no duty of disclosure at the so-called renewal.
4. Alteration: When the insured asks to change the cover mid-term, for example to increase the sum insured or change the use of the premises, the duty revives for that change.

Breaches of Utmost Good Faith: Non-Disclosure vs Misrepresentation

Breaches occur through omission or inaccurate positive statements:

• Non-Disclosure (Omission):
  • Innocent: Inadvertent omission without fraudulent intent or negligence.
  • Negligent: Failure to disclose a fact that a reasonable person would have disclosed upon reasonable inquiry.
  • Fraudulent (Concealment): Deliberate suppression of a known material fact to deceive the insurer.
• Misrepresentation (Positive Statement):
  • Innocent: False statement made with an honest belief in its truth on reasonable grounds.
  • Negligent: False statement made carelessly without reasonable grounds for belief.
  • Fraudulent: False statement made knowingly, without belief in its truth, or recklessly without caring whether it is true or false (Derry v Peek).

What Makes a Statement a Misrepresentation?

For a statement to be a misrepresentation, it must:

• be a statement of fact, not of law, opinion or belief;
• be made by a party to the contract;
• be material;
• induce the contract, meaning the other party relied on it; and
• cause the party who relied on it some loss or disadvantage.

In practice, misrepresentation and non-disclosure often overlap. A proposer who says he is in good health while knowing he has a serious illness has made a false statement and has also failed to disclose the illness, so insurers usually rely on both.

Remedies for Breach of Utmost Good Faith

The SCI study text summarises the insurer's remedies against the insured as follows.

Key points:

• Avoidance is retrospective. The insurer is not liable for any claim between the start of the contract and the date it is avoided.
• The insurer must choose to avoid or affirm within a reasonable time after discovering the breach. If it keeps collecting premiums or otherwise treats the policy as continuing, it is taken to have waived its right.
• The insurer cannot pick and choose. It must avoid or affirm the whole contract, and it cannot refuse a particular claim, or pay only part of a loss, while affirming the policy.
