Decision made by an insured or insurance company to not continue coverage for another policy period after the current policy period expires.

A refusal by an insurer to continue coverage under a policy at its expiration. Most states restrict an insurer's right to nonrenew personal lines policies.

When an insurer chooses not to offer renewal coverage on a policy for cause such as higher than expected hazards or losses, lack of compliance with safety recommendations, or because the insurer is withdrawing for a territory or from offering a type of coverage. When an insurer nonrenews coverage, it must be done within the applicable state law as far as the reasons permitted, type of notice that is sent to the insured and the amount of time the insurer must give the insured prior to policy expiration.
