Can I change a child's surname without the father's permission?

In England and Wales, the ability to do this depends on whether the father has parental responsibility. If he does not, then the mother can usually change the surname by deed poll without any difficulty. However, if the father does have parental responsibility, his consent is required before any change can be made.

Where both parents hold parental responsibility, neither can act unilaterally. If the father does not agree, the mother would need to make an application to the family court for permission. The court will then consider whether the change of name is in the child’s best interests, as the child’s welfare is always the paramount consideration. Judges are generally cautious about authorising a name change unless there is good reason to do so. The court will weigh factors such as how long the child has been known by their current name, whether the change might cause confusion at school or in social settings, and how it could affect the child’s relationship with the father.

In some situations, the court may agree to a name change where the father has little or no involvement in the child’s life, or where the child is already known in the community under a different surname. However, where the father plays an active role, the courts are reluctant to approve changes that might undermine his relationship with the child. It is also worth noting that even if the court allows a name change, the father would still retain parental responsibility unless a separate application to remove it were successful, which is rare.

This area of law can be sensitive because it touches on issues of identity, parental rights, and a child’s emotional wellbeing. Parents sometimes attempt to change a surname without consent, but this can be challenged and reversed if the other parent objects. The safest and most effective approach is always to seek either written consent or a court order.
