Change a civil partnership to a civil marriage

Anyone who has a same sex civil partnership formed in England or Wales, can change this into a civil marriage.

What is involved 

There are two possible stages to the ‘conversion’ which is a legal paper process, with the option to have a celebratory ceremony. 

Conversion without ceremony

The couple will need to: 

• attend an appointment with a superintendent registrar in the register office (this can be at any local authority) 
• bring evidence of identity, proof of address and the original civil partnership registration certificate 
• sign a declaration to confirm that the couple have not dissolved their civil partnership, and that they both wish to convert their civil partnership into a marriage 
• have the conversion registered and a certificate issued 

The couple may optionally choose to say the declaration wording aloud to one another before signing the declaration. 

Conversion with celebratory ceremony

For couples wishing to hold a celebratory ceremony, the couple will need to: 

• attend an appointment in person with a Superintendent Registrar in the register office (this can be at any local authority) 
• bring evidence of their identity, proof of address and the original civil partnership registration certificate 

A legal declaration will be drawn up for signature at a later date, but not more than one year after the appointment. 

A second stage will involve: 

• the couple both signing the declaration confirming they have not dissolved their civil partnership, and that they both wish to convert their civil partnership into a marriage – this must be done in front of a Superintendent Registrar (including those taking place in a religious building) 
• a ceremony can then be conducted by the Superintendent Registrar at the register office or at an approved premise, or by the minister for the religious building 
• after the ceremony the Superintendent Registrar will register the declaration online and a marriage certificate will be posted to the couple
