If you have 30-year term life, the coverage expires after 30 years. At this point, you will no longer have life insurance protection. If you want to continue your insurance coverage, you may have a couple options before the expiration date.
First, some policies allow you to renew for more temporary term coverage. You may also have the option to convert to permanent coverage. Both options extend coverage beyond 30 years. Regardless, your premiums will increase.
