I want to change my child’s surname to be double barrelled my partners and mine (obviously :) ) she was registered with his surname and his surname is on the birth certificate but I have since decided I would like her to have mine also and he is fine with this. I’ve read I cannot change her birth certificate but I can change her surname by deed poll. does anybody have any experience in doing this ? Will it cause her issue in the future if she has a birth certificate with a different name etc ? Not really sure how it works , Thanks in advance
