The Six Principles of Insurance — and Why They Decide Whether a Contract Stands

Last updated 2026-08-10

Insurance law keeps returning to six principles. They look like six isolated points of knowledge — but they are really six links in a single chain of logic.

If you are preparing for IIQE Paper I, this cluster belongs to Chapter 3, "Principles of Insurance" — by our users' real answering statistics, that chapter carries 30% of Paper I's weighting and 33.1% of expected lost marks, the largest block in the paper (chapter-by-chapter data).

The question each principle answers

Read in this order, they form a timeline: before the proposal → at contract → after the loss → after payment.

How the chain holds together

Step one: who may insure — insurable interest.

The policyholder must stand in a legally recognised relationship to the subject matter of the insurance: they benefit from its safety and suffer from its loss. Without that relationship, no contract can be formed. This threshold is what separates insurance from gambling, and it removes any motive to hope the loss happens.

Step two: how much truth at contract — utmost good faith.

The pricing of an insurance contract rests entirely on what the proposer discloses. The insurer cannot see the subject matter; it can only rely on what it is told. The law therefore holds both parties to a standard of honesty above that of ordinary commercial contracts.

Step three: how much is paid — indemnity.

The core of this principle is one sentence: insurance restores you to the position you were in before the loss — it does not leave you better off. That is why property insurance carries sum-insured ceilings and requires proof of actual loss. Life insurance sits outside this principle — a life has no market price, so the amount payable is fixed when the contract is made.

Step four: after payment — subrogation.

Where the loss was caused by a third party, the insurer, having paid, acquires the right to recover from that third party. This follows necessarily from indemnity: if the insured kept both the insurance payment and the third party's compensation, they would end up better off than before the loss — which breaks step three.

Step five: how multiple policies share — contribution.

Where the same subject matter and the same risk are covered by several policies, the insurers share the loss proportionately, and the insured's total recovery is still capped at the actual loss. Again a corollary of indemnity — buying two policies does not mean being paid twice.

Step six: which cause counts — proximate cause.

A loss usually sits at the end of a chain of causes. The proximate cause is not the one nearest in time, but the one dominant in effect, whose chain of causation has not been broken. It decides whether the loss falls within what the policy covers.

One angle that holds the whole chain together

Principles three, four and five (indemnity, subrogation, contribution) are three faces of the same idea:

Insurance pays your actual loss — no more, no less.

• How much is paid → capped at the actual loss (indemnity)
• Someone else's liability must not become your windfall → the insurer pursues it in your place

(subrogation)

• Buying several policies does not stack the payout → the insurers share it between them (contribution)

Hold on to that one sentence and the three principles no longer need to be memorised separately.

The first (insurable interest) and the sixth (proximate cause) guard the two ends: one controls who is entitled to enter; the other, what counts. The second (utmost good faith) runs through the whole.

For the examination

• This cluster belongs to Chapter 3 of Paper I, which carries 30% of the paper's weighting and

33.1% of expected lost marks — the single largest source of lost marks in the paper

• Our users' practice accuracy on this chapter is 65.9%, among the lower chapters of Paper I
• The typical question format is discrimination: which principle applies to which scenario, and

which two are easily confused

⚠️ This is a practice accuracy rate, not a pass rate. The two are not convertible. The sample is 9 candidates and 7,914 answers in total (4,057 on Paper I) — still small.
