When the child’s name is registered, the parents can choose
whether the mother’s or the father’s surname is recorded on the
birth certificate. However, subsequent to registration, the child’s
surname on the birth certificate can only be changed from the
mother’s surname to the father’s surname. If the child was
registered with the father’s surname it is not possible to change
it to the mother’s surname except by Deed Poll, although this
would not result in a change to the birth certificate.
