An endorsement is part of your insurance policy, and it will remain in effect typically as long as your policy is in force, according to the National Association of Insurance Commissioners. Some endorsements can have a limited term, which would be specified in your policy. You can also renew an endorsement when you renew your policy.

Other types of endorsements may include water backup coverage, which you may be able to purchase to supplement a homeowners insurance policy. On an auto insurance policy, you may be able to purchase an endorsement to provide expanded protection for a new car.

If you have questions about what your endorsement options are or would like to learn more about how endorsements work, contact your insurance provider.
