What age does someone have to be before they can change their name by deed poll? The parents of the girl in question have divorced and her mother is getting married again, and she would like to change her daughters name to that of her new stepfather.
She will have to wait until she’s 18 before she can change her name formally without either the consent of both parents or a court order. The girls father shares parental responsibility with the mother, and his consent to the name change has to be sought. Otherwise the consent of the court is needed. It’s most unlikely this would be granted unless the girl has very special reasons for wanting to change her name.
