A waiver of premium (WOP) rider is optional coverage on your life insurance policy that suspends your life insurance premium payments if you become disabled. The rider acts as a safety net, ensuring your policy remains active even when you can't afford payments due to disability.
Without this rider, missing premium payments would cause your policy to end, leaving your beneficiaries without coverage. The waiver of premium rider prevents this by covering payments until you recover from your disability or reach the rider's age limit.
