Make an appointment at the register office where you wish to make the conversion. You will complete a legal declaration with details on about you and your civil partnership, and once you sign this declaration with the Superintendent Registrar, you will both be married. No witnesses need to be present.
Your marriage is then registered, and we will issue you with a marriage certificate, which you can collect from us or we can post to you.
This option costs £50, plus £12.50 for each marriage certificate.
