How to Change Your Child's Name in Northern Ireland

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

There are two legal ways to do it. You can apply through the government service, or you can use a deed poll, the traditional method of changing a name. Both are equally valid in law.



This guide explains who needs to agree, how both routes work, and how to make your child's name change official.

The Two Ways to Change Your Child's Name

Whichever option you choose, the outcome is the same. Your child's new name is legally recognised by schools, GPs, HM Passport Office and every other organisation in Northern Ireland and across the UK.

The Government Service

The government service for children is run by the General Register Office for Northern Ireland (GRONI). It costs £35, plus £15 for the name change certificate.

Only qualified applicants can apply. The rules on who qualifies depend on the parents' marital status, who holds parental responsibility, and whether both parents are living. In most cases, both parents must apply together.

The application is paper-based. You download and print the form, and each applicant must sign it in front of a lay magistrate, a Justice of the Peace, or a practising solicitor who will charge for the service. The completed form then goes to GRONI, by post or in person, together with the fee and a certified copy of your child's birth certificate. It takes several weeks to process.

A child's name can only be changed once through the government service. Once changed, it cannot be changed again or reverted to the original name while your child is under 18.

A Deed Poll

A deed poll is a legal document declaring your child's change of name. It is the traditional way of changing a name, in use for more than a hundred years.

There's no application form to print and no need to get your child's birth certificate certified. Everyone with parental responsibility signs the deed poll in front of witnesses, and it becomes legally binding as soon as it's signed. There is no restriction on changing the name again in future.



A child deed poll from Deedly costs £23 and arrives at your door within days, ready to sign.

Who Can Change Their Child's Name

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 Northern Ireland 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 Northern Ireland 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 prepared to Northern Irish requirements and printed on premium ivory parchment paper, with its own serial number and embossed gold seal. 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 over 18, 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. Unlike the government route, there's no central record of the change. The deed poll itself is the legal proof.

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.
