What is 40 year term insurance?

It's a type of temporary life insurance policy providing you with life insurance coverage that lasts for a period of forty years.

That means, if you (the insured person) dies during the forty year period, while insured by the policy, the death benefit is paid out to your beneficiary.

There are a few insurers offering term life coverage for 40 years.

However, in order to qualify you need to be healthy and age 45 or under, usually.
