Term life policies last for a specific period of time, usually for a period of 30 years or less.
So, you only have the life insurance for the number of years you choose for your "Term".
You may be able top choose term life coverage for 10, 15, 20 or 30 years, but the maximum term may depend on your age and health.
If you need life insurance for a longer period of time, you would need to renew your term life policy for another term, which is usually up to 10 years when your original term life insurance plan expires.
