Well, that depends on what type of life insurance policy you have.
If you own a permanent life insurance policy, your life insurance coverage will last your entire lifetime, as long as you pay your premiums.
If you have a term life insurance policy, your life insurance policy will expire at the end of your policy term.
So, if you have a 15 year term life policy, your coverage ends after fifteen years.
Keep in mind, some term life plans offer renewability, which means you may renew your coverage for another term (usually up to 10 years) when your original term policy expires.
