Whole life insurance is a form of long‑term life assurance under which the insurer is contractually obliged to pay a lump sum on the death of the life assured, whenever that occurs, provided premiums are maintained (or a fully paid‑up status is reached). Unlike term insurance, cover is not limited to a fixed period and typically includes a savings or investment element affecting surrender value and premium levels.The term is primarily a descriptive one used in insurance practice, policy documentation and financial regulation, rather than being exhaustively defined in statute. Regulatory treatment and consumer protection requirements derive mainly from financial services legislation and rules (for example, the UK Financial Services and Markets Act regime and FCA rules; and equivalent Central Bank of Ireland frameworks), rather than specific “whole life” legislation.Key legal issues for advisers include insurable interest at inception, non‑disclosure and misrepresentation, policy assignment and trust planning, inheritance tax or capital acquisitions tax consequences, and treatment on divorce, bankruptcy or death. Usage and core legal characteristics are broadly consistent across England and Wales, Scotland, Northern Ireland and Ireland, although tax treatment, regulation and succession rules differ between jurisdictions and must be checked in each case.
