Changing your name can be a powerful and personal decision, whether it’s for cultural, gender, family, or identity reasons. But what age can you change your name? The rules vary depending on whether you’re applying for yourself or on behalf of a child.
This guide breaks it down clearly and simply.
Can Children Have Their Name Changed?
Yes — a child’s name can be changed at any age, even as a baby. However, a parent or guardian must apply on their behalf. In England and Wales, you can change a child’s name by enrolling a deed poll or using an unenrolled deed poll, depending on the level of recognition required.
To change a child’s name:
- They must be under 16 years old
- Everyone with parental responsibility must give written consent
- The child should not object if they are mature enough to understand
What Age Can You Change Your Name?
If you’re 16 or over, you can change your name yourself by deed poll, and you don’t need parental permission.
At 16, you’re considered to have enough understanding to make this decision under UK law (this is known as “Gillick competence”). Once your name is changed by deed poll, it can be used to update all official records, including your passport, bank accounts, driving licence, and GP records.
- You don’t need to go to court
- No parental approval is required
- A deed poll is fully recognised by UK government departments
What About People Aged 18 and Over?
At 18, you gain full adult status in the UK, but the process of changing your name is exactly the same as it is at 16. You simply apply for an adult deed poll, and once issued, you can start using your new name straight away.
What If You're Under 16 and Want to Change Your Name?
If you’re under 16 and want to change your name, your parents or guardians will need to do it for you. Even if you’re mature enough to understand, UK law requires the consent of those with parental responsibility until you’re 16.
That said, your wishes should be taken into account, especially if you’re older (e.g. 13–15) and understand what changing your name means.
Summary: Minimum Age to Change Your Name
- Aged 0–15:
You can change your name, but only with parental or guardian consent. An adult with parental responsibility must apply on your behalf. - Aged 16–17:
You can change your name yourself using a deed poll. You do not need parental permission. - Aged 18 and over:
You have full capacity to change your name independently; the process is the same as it is at 16.
What Documents Are Needed?
To change your name using a deed poll, you’ll need:
- Your current name and date of birth
- A UK address
- Parental details (for children under 16)
- Payment for your chosen deed poll package
Once completed, you’ll receive your official deed poll documents by post, ready to use for updating all personal records.
Thinking of Changing Your Name at 16?
Many teenagers choose to change their name at 16 for reasons such as:
- Gender identity
- Cultural or religious reasons
- No longer wanting to use a parent’s surname
- Wanting a fresh start as they become more independent
Whatever your reason, Change My Name offers a supportive, private and official way to make the change official.
