A marriage certificate (sometimes: marriage lines) 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 some 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.
A marriage certificate may be required for a number of reasons. It may be required as evidence of change of a party's name, on issues of legitimacy of a child, during divorce proceedings, or as part of a genealogical history, besides other purposes.
In the United States, the certificate of marriage is recorded on the same document as the marriage license or application for marriage. While each state creates their own form for use with the recording of marriages, most states have a specific portion of the record to be completed by the official performing the ceremony. In some states, this portion also includes places for the parties to indicate a change in name, if any (The Marriage certificate can be used as documentation to justify a legal name change but not as proof that a name change has occurred). If there is not a place for a name change, the name is changed as requested on government documents with proof of marriage.

On 1 July 1837 civil registration was introduced in England and Wales, providing a central record of all births, deaths and marriages. A Registrar General was appointed with overall responsibility and the country was divided into registration districts, each controlled by a superintendent registrar. Under this system, all marriage ceremonies have been certified by the issuing of a marriage certificate whose details are also stored centrally. From that date, marriage ceremonies could be performed, and certificates issued either by a clergyman of the Church of England, in a parish church, or by a civil registrar in a civil register office. Marriages performed according to the ceremonies of Quakers and Jews also continued to be recognised as legal marriages, and certificates were issued.
