Whether you want your child to share your maiden name, mirror a new step-family, or take on a double-barrelled name to reflect both parents, the law approaches this issue with a great deal of caution. A surname is often viewed by the Court as an integral part of a child’s identity.
If you want to change any part of your child’s name via Deed Poll, you must obtain the written consent of every single person who holds Parental Responsibility for that child.
Who holds Parental Responsibility?
A birth mother will automatically have parental responsibility for the child upon their birth. If at the time of the child’s birth, the parents are married or in a civil partnership, the other parent will also automatically have parental responsibility.
Where the parents are not married at the time of the child’s birth, the other parent will not automatically have parental responsibility and will only obtain it if they are named on the birth certificate.
Even if a child lives with you full-time under a Child Arrangements Order, that does not give you the right to change their surname unilaterally. If the other parent has PR and says “no,” you cannot legally proceed without a court order.
What Happens if There Is a Disagreement?
If one parent refuses to consent, the parent wishing to make the change must apply to the Family Court for a Specific Issue Order under Section 8 of the Children Act 1989. If a parent tries to change a name informally (such as registering them at a new school under a different name), the objecting parent can apply for a Prohibited Steps Order to stop it.
Before making an application, there is a requirement for parents to attend a Mediation Information and Assessment Meeting (MIAM) to see if the issue can be resolved amicably.
What Does the Court Look At?
When a surname dispute reaches the Court, the Court’s primary consideration is always the welfare of the child. The Court does not take into consideration what is administratively easier for the parents; they consider what is best for the child’s emotional well-being and identity.
The legal framework Judges use is built on several landmark cases:
Dawson v Wearmouth [1999]
The House of Lords established that a child’s existing surname should not be changed lightly. The Court ruled that the person applying for the change must actively demonstrate that changing the name will clearly improve the child’s welfare. Continuity and stability carry massive weight, and a name change will rarely be granted if its primary purpose is to sideline or marginalise the other parent.
Re W, Re A, Re B (Change of Name) [1999]
The Court of Appeal laid down explicit guidelines for Judges. They emphasised that the registration of a child’s birth name is a legal fact that should not be undone without “strong relevance” or clear evidence of benefits to the child. The court will look at:
- The child’s relationship with both parents.
- The reasons why the name was chosen originally.
- Any evidence that a change would harm or enhance the child’s sense of identity.
Re R (Surname: Using Both Parents) [2001]
Family structures evolve, and the Courts have increasingly recognised the value of compromise. In this case, the Court of Appeal supported the growing trend of double barrelling a child’s surname. Judges sometimes view a hyphenated name favourably because it preserves the child’s link to both sides of the family, rather than cutting one parent out.
It should be noted that every case turns on its own facts and as such, legal advice from an early stage is essential.
