Could a Claim Be Refused Over Family History?

If a family history question on a life insurance application was answered wrongly, the policy does not automatically collapse and the claim is not automatically refused. An insurer cannot simply keep the premiums and walk away because an answer about a parent's or a sibling's illness later turns out to be inaccurate. Whether a rejected life insurance claim over family history is lawful turns on a specific piece of UK law — the Consumer Insurance (Disclosure and Representations) Act 2012 — and on which of two very different kinds of mistake was made.

The old world, in which an insurer could void a policy for almost any non-disclosure, is gone. Since the 2012 Act came into force, an insurer that wants to refuse or cut a claim because a family history answer was wrong has to clear a series of hurdles in order. It must show there was a "qualifying misrepresentation", and then show which category the mistake falls into, because the category decides the remedy. Nothing here is a formality, and the burden sits with the insurer, not with the grieving family.

So the short version is this: a wrong answer might affect a claim, but it does not by itself destroy the policy. What happens next depends almost entirely on whether the mistake was careless or deliberate — and those two words have precise meanings that are worth understanding before anyone accepts a refusal at face value.

The short answer, and what changed in 2012

Before 2012, consumers were held to a duty of "utmost good faith" that in practice let insurers refuse claims over innocent mistakes and answers to questions they had never actually asked. It was widely seen as unfair, and Parliament replaced it for consumer policies with the Consumer Insurance (Disclosure and Representations) Act 2012.

The 2012 Act does two things that matter here. It removes the old duty to volunteer information the insurer never asked about, and it replaces it with a narrower duty: to take reasonable care not to make a misrepresentation when you answer the questions you are asked. If the insurer did not ask a clear question about a particular relative or condition, a consumer is generally not at fault for not mentioning it.

That reframes the whole argument at claim stage. The question is no longer "did the customer disclose everything?" but "did the customer answer the insurer's actual questions with reasonable care, and if not, did that inaccuracy make a real difference?" You can read the full text of the Consumer Insurance (Disclosure and Representations) Act 2012 on legislation.gov.uk.

What a "qualifying misrepresentation" actually means

An insurer cannot act on just any imperfect answer. Under the Act it must establish a qualifying misrepresentation, and that has two limbs, both of which have to be met.

The first limb is that the consumer failed to take reasonable care not to make a misrepresentation — in plain terms, that the answer was inaccurate and that a reasonably careful person would not have given it. The second limb is that the misrepresentation mattered: the insurer must show that, had it known the true position, it would either have declined the application altogether or offered it on different terms. If a correct answer would have changed nothing, there is no qualifying misrepresentation and the claim stands.

This second limb catches a lot of family history worries. Some family history is neutral to an insurer, or was already captured by other answers, or concerns a relative or condition the insurer does not weight. If the honest answer would have produced the identical policy on identical terms, the inaccuracy is not "qualifying", however untidy it looks. The insurer has to be able to show the difference, not merely assert it.

Careless, or deliberate and reckless — the fork that decides everything

Once a qualifying misrepresentation is established, the Act sorts it into one of two categories, and this is where outcomes diverge sharply.

A careless misrepresentation is an honest mistake — a misremembered age at death, a genuine misunderstanding of a badly worded question, a relative whose diagnosis you got slightly wrong. A deliberate or reckless misrepresentation is one where the consumer either knew the answer was untrue, or did not care whether it was true or false. The Act presumes a misrepresentation is careless unless the insurer proves otherwise, so the burden of showing dishonesty rests on the insurer.

The distinction is not about how serious the underlying fact was; it is about the applicant's state of mind. Forgetting that a grandparent had diabetes is careless at worst. Ticking "no family history of heart disease" while knowing both parents had heart attacks in their fifties is a different thing entirely. Because the presumption favours the consumer, a family faced with a refusal should ask the insurer, in writing, exactly which category it is alleging and what evidence supports it.

What a careless mistake actually costs: proportionate remedies

If the misrepresentation was careless, the insurer does not get to keep the premiums and refuse the claim. It gets a proportionate remedy — it is put back into the position it would have been in had the question been answered correctly.

In practice that works through a few outcomes. If the insurer would still have offered cover but at a higher premium, the claim is usually reduced proportionately — the payout is scaled by the ratio of the premium paid to the premium that should have been charged. If the insurer would have offered cover on different non-price terms, those terms are treated as if they had applied. And if the insurer would have declined the application altogether, the claim can be refused, but the premiums are normally returned. The thread running through all of it is restoration, not punishment.

This is why a refusal letter should never be read as the end of the matter. A family told a claim is being declined outright should check whether the honest answer would truly have led to a decline, or merely to a higher premium — because in the second case the correct outcome is a reduced payout, not nothing. If the disagreement is about a health history the insurer relied on, our note on how to ask an insurer to show the evidence behind a decision sets out the questions worth putting in writing.

"I genuinely did not know" — the reasonable-care standard

A great deal of family history is simply unknown to the person filling in the form, and the Act allows for that. The duty is to take reasonable care, judged against what a reasonable consumer in the applicant's position would have known and how clearly the insurer put the question. It is not a duty to research your relatives or to know things you had no way of knowing.

Two consequences follow. First, vague, compound or badly worded questions count against the insurer, not the customer — if a question could reasonably be read more than one way, an answer consistent with a sensible reading is not careless. Second, an honest "not known" is an acceptable answer where the information genuinely is not available to you, as it often is for adoptees or where a family is estranged. If a parent's condition is disclosable in principle but you were never told the details, answering with what you actually knew is taking reasonable care. The same logic governs how a specific condition such as a parent's early-onset dementia sits on an application: you answer the questions asked, to the standard of what you reasonably knew.

How it plays out at claim stage

When a life claim is submitted, the insurer may check the application answers against the deceased's medical records, obtained with the appropriate authority. If it finds a discrepancy on a family history question, it has to work through the Act's steps rather than simply declining: was the answer inaccurate, would a correct answer have changed the terms, and was the mistake careless or deliberate?

Because the burden is on the insurer at each step, a family is entitled to see the reasoning. Ask which specific question is said to have been answered wrongly, what the correct answer would have been, what the insurer would have done differently with that answer, and which category of misrepresentation is alleged. A refusal that cannot answer those four questions clearly is a refusal worth challenging. This matters most in exactly the situation where cover was the family's safety net — the aftermath of a death with no other provision in place is not the moment to accept a thin explanation.

If you think a claim was wrongly refused

Start with the insurer's own complaints process, in writing, setting out why you believe the answer was accurate, or was careless rather than deliberate, or would not have changed the terms. Attach anything that supports it. Under FCA rules the firm has up to eight weeks to give a final response.

If the final response does not resolve it, or eight weeks pass without one, you can refer the complaint to the Financial Ombudsman Service free of charge. The Ombudsman looks at whether the insurer applied the 2012 Act correctly and whether the outcome was fair, and it can direct a firm to pay a claim or a proportion of it. You normally have six months from the final response letter to refer, so do not let that window close. Free help with the process is available from Citizens Advice. None of this depends on the country you live in, because the Consumer Insurance Act 2012 and the Ombudsman both cover the whole UK.

Scotland and Northern Ireland

This is one of the areas where UK law really is uniform. The Consumer Insurance (Disclosure and Representations) Act 2012 applies across England, Wales, Scotland and Northern Ireland, and the careless-versus-deliberate framework and its proportionate remedies work the same way in Glasgow or Belfast as in Cardiff or London. The Financial Ombudsman Service covers the whole of the UK as well.

Where differences appear, it is in the surrounding machinery rather than the insurance test itself — how an estate is administered, or how a dispute would proceed if it ever went to court rather than to the Ombudsman. Those differences do not change whether a claim should be paid. For the wider context of how family history and inherited risk are treated across cover generally, see our guide to family history, inherited risk and the odds. If you are arranging cover now and want it done cleanly, you can get life insurance quotes and answer every question carefully at the outset, which is the surest way to keep a future claim out of this territory altogether.

Frequently asked questions

Can a claim be refused because of a family history question?

It can be affected where the question was answered inaccurately, but not automatically. The Consumer Insurance (Disclosure and Representations) Act 2012 requires the insurer to show a qualifying misrepresentation, meaning an inaccurate answer that actually made a difference to the terms it offered. If a correct answer would have changed nothing, the claim stands, and the burden of proof is on the insurer throughout.

What is the difference between careless and deliberate?

A careless answer attracts a proportionate remedy: the insurer does what it would have done had it known, which may mean reducing the payout or applying the terms it would have set. A deliberate or reckless misrepresentation, where the applicant knew the answer was untrue or did not care, allows the policy to be avoided and the claim refused. The Act presumes carelessness unless the insurer proves otherwise.

What if I genuinely did not know a relative's diagnosis?

The duty is to take reasonable care, judged against what a reasonable consumer would have known and how clearly the question was put. Not knowing something you had no way of knowing is not a misrepresentation, and vague or badly worded questions count against the insurer. An honest "not known" is an acceptable answer where the information genuinely was not available to you.
