Conversion appointment and ceremonies

Conversion appointment 

A legal declaration will be drawn up for both of you to sign with the registrar present. Your marriage will then be registered and a marriage certificate will be issued. 

There is no need for you to bring witnesses to your conversion appointment. 

Conversion ceremonies 

You can choose to follow your conversion appointment with a ceremony at any of Westminster’s over 150 licensed ceremony venues

If you opt to have a ceremony, your conversion will take place in two stages: 

1. You will attend a conversion appointment. 

2. You will have your ceremony where your marriage will be registered. Your marriage certificate can then be collected from the Register Office or posted to you. 

Your conversion appointment can take place a maximum of one year prior to your ceremony.
