Life insurance does pay out when someone dies with dementia or Alzheimer's disease, as long as the death falls inside the policy term, the premiums were kept up and the application was answered correctly. The main exception is an over-50s plan in its opening period, when a death from illness may bring back only the premiums paid. What decides a claim is what the policy says about those points, and the cause of death is not the first thing to look at.

If you are checking a policy for someone you love, take it at your own pace. When you would like another pair of eyes on the wording, your name and number go through the form on this page to an FCA-authorised broker, and the phone call back costs nothing.

Does it matter that dementia was the cause of death?

Legal & General's direct Life Insurance terms (QGI14872 - 2026/10) say: "Life insurance will pay a lump sum if the life insured dies or is diagnosed with a terminal illness during the term of this policy." Its reasons for refusing or reducing a claim include answers given incorrectly when applying and a policy that lapsed through missed payments, and in the first year a death by suicide also stops a payment.

Aviva's Life Insurance+ conditions (AL50002 02/2026) pay "if the life covered dies during the policy term", with a similar first-year suicide exception. So on these documents the questions are about timing, payment and honesty at the start. Illness and old age as causes of death have their own page: does life insurance pay out for natural causes.

What if dementia, or early memory problems, were not mentioned when applying?

The Consumer Insurance (Disclosure and Representations) Act 2012 says: "It is the duty of the consumer to take reasonable care not to make a misrepresentation to the insurer." What follows depends on the kind of mistake. If it was deliberate or reckless, the insurer may refuse all claims; if it was careless, the Act's remedy depends on what the insurer would have done had it known: refuse claims but return the premiums, treat the policy as if it had been on the different terms, or reduce a claim in proportion to the higher premium it would have charged.

Aviva reported in March 2026 that, of the small share of claims it declined, the leading cause remained misrepresentation of relevant information, in particular health and lifestyle information. The Financial Ombudsman Service looks at whether the questions asked were clear and whether the person took reasonable care to answer correctly. It adds: "Sometimes it’s acceptable that customers haven’t told insurers certain information." For the wider rules, see refused life insurance claims and disclosure requirements. Whether an early symptom should have been mentioned for a given question is worth raising with the broker, free, on that call-back.

Can the terminal illness benefit be paid for dementia?

Some life policies pay the cover amount early, while the person is still alive, if a consultant diagnoses a terminal illness. Legal & General defines it in two parts, and the second reads: "In the opinion of your hospital consultant and our Medical Officer (a qualified doctor employed by Legal & General), the illness is expected to lead to death within 12 months." Aviva's Life Insurance+ conditions use a similar test: an illness that has no known cure or has progressed to the point where it cannot be cured, and the attending consultant's opinion that it is "expected to lead to death within 12 months".

Both definitions say "an illness" and do not name particular conditions, so they turn on the medical view of the time left: the consultant's, and at Legal & General its Medical Officer's as well. Aviva's policy summary for its Life Insurance Plan (DA03008 05/2023), a different product from Life Insurance+, lists among the situations where it will not pay being "diagnosed with a terminal illness and are expected to live longer than 12 months". Whether a dementia diagnosis meets a given insurer's wording at a given stage is for that insurer to decide, and a broker can explain how claims like this are usually looked at.

Legal & General adds that the benefit "is an advanced payment of the death benefit", so it "may be less than would have been paid at death", and that it cannot be claimed after the life insured has died. See also how terminal illness benefit works.

Critical illness cover is a different product and can pay on a diagnosis; see whether dementia is a critical illness, and what critical illness cover pays on death.

Do over-50s plans pay out for dementia in the first year or two?

Aviva says it asks no health questions and guarantees to accept people aged 50 to 80, and Legal & General describes its plan the same way. In return, both plans have an opening year in which a death from illness does not pay the full cash sum. Aviva's over-50s policy conditions (DA03016 07/2023) define natural causes as sickness, disease or physical disorder, so a death from dementia in that year falls under the natural-causes rule rather than the accident rule.

Nobody needs to work out an opening period alone: tell the broker about the plan on the call you get after completing the form here, which costs nothing.

For a death from illness in that first year, Aviva gives back a sum matching the premiums paid and Legal & General refunds the premiums, while an accidental death is paid in full on both. Other providers' opening periods are set side by side in natural causes and life insurance and funeral cover waiting periods.

Each document carries further conditions. Legal & General also warns that "total premiums paid may be greater than the cash sum we pay on death".

Who is paid, and how is a claim made?

Legal & General says it will "pay the amount of cover to you", and that if the owner of the policy has died the payment goes to their personal representative, usually the executor named in the will; if the policy is in trust, it pays the trustees. For a claim it needs the life insured's death certificate and date of death. For other arrangements, see what a life insurance beneficiary is.

The claim itself goes to the insurer's claims team. Should any of the wording be unclear before you start, jot those clauses down: a broker can walk through each one on the free call-back that follows sending the form on this page.

Frequently asked questions

Does life insurance pay out for Alzheimer's disease?

The answer is the same as for other types of dementia: Alzheimer's is an illness, so a death from it is judged against the term, the premiums and the application answers. The over-50s opening periods above also apply.

What happens if someone with dementia can no longer pay the premiums?

Legal & General says a policy is "deemed cancelled" if a premium stays unpaid 60 days after its due date, and Aviva says its over-50s plan ends 60 days after a premium falls due and is missed, and premiums already paid are not refunded.

Is a death after the policy has ended covered?

Aviva's Life Insurance Plan policy summary (DA03008 05/2023) lists dying "outside the policy term" among the reasons it will not pay, so a term policy that has run out does not pay on a later death.
