How do I change my child’s surname?

Changing a child's name is a major decision that generally requires consent from all guardians. Under the Births, Deaths, Marriages, and Relationships Registration Act 1995, a child's name can be changed by all guardians agreeing, or if there is a dispute, by a court order. If the father is a guardian and refuses consent, you can apply to the Family Court under the Care of Children Act 2004, which will decide based on the welfare and best interests of the child, considering factors such as the child's identity, links with each parent, their wishes and the reasons for the change. Changing the name without the father's agreement or an order can cause problems, for example with passports. Consider negotiating a compromise, such as a double-barrelled surname.
