Yes, you can easily change your name by using your Civil Partnership Certificate, in the same way as married people would use their Marriage Certificate, as long as the name change is to be a straightforward change. If, for instance, partners want to both take one of their surnames, it is possible to do this without applying for a Deed Poll, as long as you still have the original Civil Partnership Certificate. However, if the name change is more complicated, you will need a Deed Poll for both partners. If, for instance, the partners want to double-barrel their surnames, or make a new surname out of an amalgamation of both of their existing surnames, they will both need a Deed Poll. For further information, please go to the Deed Poll Information list at the top left of this page, and click on “Marriage”, “Civil Partnership/Same-Sex Marriage” and “Passports”.
