How soon you can get married or register a civil partnership
The very earliest that you can be married or have a civil partnership is 29 days after you have both given notice at your local register office. If either of you is subject to immigration control, and are therefore referred to the Home Office, they may extend the notice period to 71 days.
The Home Office will notify you after your notice appointment if they wish to extend your notice period. In rare instances they may prevent the marriage or civil partnership from proceeding.
