Changing your name

If you’re changing your name, whether it’s because of marriage, divorce or deed poll, we need evidence of the change. You can use any one of the following documents as evidence:


• Marriage Certificate
• Unenrolled or enrolled change of Name Deed / Deed Poll (this must be accompanied by photo identification such as Passport or Driving License)
• Civil Partnership Certificate
• Written Statement of proof of change of name from a professional body e.g. solicitor (this must be accompanied by photo identification such as Passport or Driving License)
• A Decree nisi is acceptable as proof of a change back to a maiden name, if accompanied by a birth certificate.
