Life insurance (or commonly final expense insurance or life assurance, especially in the Commonwealth) is a contract between an insured (insurance policy holder) and an insurer or assurer, where the insurer promises to pay a designated beneficiary a sum of money (the “benefits”) in exchange for a premium, upon the death of the insured person.

Depending on the contract, other events such as terminal illness or critical illness can also trigger payment. The policy holder typically pays a premium, either regularly or as one lump sum. Other expenses (such as funeral expenses) can also be included in the benefits.
