You need to be 16 or over to make your own deed poll.
Make your deed poll using the following wording:
“I [old name] of [your address] have given up my name [old name] and have adopted for all purposes the name [new name].
“Signed as a deed on [date] as [old name] and [new name] in the presence of [witness 1 name] of [witness 1 address], and [witness 2 name] of [witness 2 address].
“[your new signature], [your old signature]
“[witness 1 signature], [witness 2 signature]”
A specialist agency or a solicitor can make the deed poll for you instead - they may charge a fee.
After you’ve made it, you can use your deed poll as proof of your new name.
Some organisations will only accept a deed poll as proof of your new name if it’s been ‘enrolled’ with the courts. Ask the organisation you’re dealing with (for example, your bank) if they need to see your deed poll certificate.
