"A marriage certificate (sometimes: marriage lines[citation needed]) is an official statement that two people are married. In most jurisdictions, a marriage certificate is issued by a government official only after the civil registration of the marriage.
In some jurisdictions, especially in the United States, a marriage certificate is the official record that two people have undertaken a marriage ceremony. This includes jurisdictions where marriage licenses do not exist. In other jurisdictions, a marriage license serves a dual purpose of granting permission for a marriage to take place and then endorsing the same document to record the fact that the marriage has been performed." - (en.wikipedia.org 09.01.2022)
