Where you'll actually need to show your marriage certificate

A marriage certificate proves you are legally married. You will need to show the original or a certified copy when you change your name, update government IDs, add a spouse to insurance, file joint taxes, claim spousal benefits, or settle a divorce. Banks, employers, and government agencies all ask for it because they need proof that the marriage happened and is recorded in a public record.

Most places that ask for it will accept either the original certificate or a certified copy—a photocopy stamped and signed by the vital records office that issued it.
