Change your child's name in Wales

Changing your child's name in Wales is straightforward, but it requires consent from everyone with parental responsibility.

Once everyone agrees, the change is made with a deed poll, a legal document declaring your child's change of name. It has been the traditional way of changing a name for more than a hundred years. Everyone with parental responsibility signs it in front of witnesses, and it becomes legally binding as soon as it's signed.

This guide explains who needs to agree, how the process works, and how to update your child's records afterwards.

Eligibility

You can change your child's first name, middle name, surname, or any combination of them if they're under 16. A parent or guardian applies on their behalf, with consent from everyone who holds parental responsibility.

At 16, your child can change their own name without parental consent. The process is the same as for adults, and our guide to changing your name in Wales explains it in full.

Choosing your child's new name

You can choose almost any name for your child, with only a few restrictions. The new name cannot include numbers or symbols, apart from hyphens and apostrophes, and it cannot contain offensive language or be intended to mislead.

Parental responsibility and consent

In most situations, everyone with parental responsibility must agree to your child's name change.

Who has parental responsibility

Mothers automatically have parental responsibility from birth.

Fathers have parental responsibility if they were married to the mother at the time of birth, or if they're named on the birth certificate for births registered in Wales on or after 15 April 2002. Fathers can also gain parental responsibility through a formal agreement with the mother or through a court order.

Others can hold parental responsibility if they've legally adopted the child, been appointed as a guardian, or been granted it by a court order.

Consent requirements

If both parents have parental responsibility, both must consent. This applies even if you're separated, divorced, or your child lives with one parent.

If only one parent has parental responsibility, only that parent needs to consent. This is most common when the father isn't named on an older birth certificate, or when one parent has died.

When more than 2 people hold parental responsibility, such as both parents and a guardian, all of them must agree.

If someone won't or can't consent

If someone has lost parental responsibility through a court order, you don't need their agreement. If you've adopted your child, check your adoption order to see whether consent from birth parents is needed.

If another parent refuses to consent, you have 3 options: reach an agreement through discussion or mediation, apply to court for permission to change the name, or wait until your child turns 16 and can apply themselves.

If you cannot locate the other parent, you cannot proceed on your own. You'll need to make genuine efforts to contact them and keep evidence of your attempts, or apply to court for permission. The court will expect to see that you've truly tried to reach them.

Getting your child's deed poll

1. Ensure you have consent

Before applying, make sure everyone with parental responsibility agrees to the name change. They'll all need to sign the deed poll.

2. Apply for the deed poll

Complete the online application with your child's current name and their new name.

Your child's deed poll is drafted to the requirements of the law of England and Wales, then printed on parchment paper, embossed with a seal and assigned a unique serial number. Royal Mail delivers it to your door within days, ready to sign.

3. Sign and witness

Everyone with parental responsibility signs the deed poll, and each signature needs 2 independent witnesses present. The witnesses must be 18 or over, not related to any of you, and not living at your address.

Once signed and witnessed, the deed poll is legally binding and your child's name is officially changed.

Updating documents and records

Once the deed poll is signed and witnessed, your child's name is legally changed. There's no further application to make and nothing to register. The deed poll itself is the legal proof of the name change.

You use it to update your child's records with each organisation directly. You show or send the deed poll, and they update their records to the new name. Each organisation makes its own change, so your child's records are updated one by one rather than all at once.

For most children, that means their school, their GP and dentist, and HM Passport Office if they have a passport. If your child has a savings account, a young person's travel card, or is registered with any clubs or activities, those records are updated the same way.

There's no deadline for any of this. Most parents update the important records within a few weeks, and anything missed can be updated whenever it comes up.

Special cases

Step-parents

Being married to your child's parent doesn't give you parental responsibility or the right to change your child's name. You need consent from everyone who holds parental responsibility, or you must gain parental responsibility yourself first.

If parents disagree

When parents can't agree, the options are mediation, court proceedings, or waiting until the child is old enough to decide for themselves. Courts consider what's in the child's best interests and will hear both parents' reasons before deciding.

If the other parent cannot be located

You cannot change your child's name simply because the other parent is out of contact. Their consent is still required if they hold parental responsibility. Make genuine attempts to reach them and keep a record of each one, since a court will want to see this evidence if you apply for permission to proceed without them.
