In the UK, changing your name on your passport and driving licence involves a legal process. There are several ways to change your name legally, and the process may vary slightly depending on your circumstances. Here are some common methods:

1. Deed Poll:

   • A Deed Poll is a legal document that allows you to change your name. You can apply for a Deed Poll through various online services or by hiring a solicitor.
   • Once you have the Deed Poll, you can use it to update your name on your passport and driving licence. Submit the Deed Poll along with the necessary application forms to the respective authorities.

2. Statutory Declaration:

   • You can make a Statutory Declaration, a sworn statement confirming your intention to change your name. This declaration needs to be signed in the presence of a solicitor or commissioner for oaths.
   • Submit the Statutory Declaration along with the required application forms to update your name on your passport and driving licence.

3. Marriage or Civil Partnership:

   • If you get married or enter into a civil partnership and choose to take your spouse or partner's surname, you can update your name on your passport and driving licence using your marriage or civil partnership certificate.
   • Submit the relevant certificate along with the application forms to the appropriate authorities.

4. Divorce or Dissolution of Civil Partnership:

   • If you revert to a previous name after a divorce or dissolution of a civil partnership, you can use the decree absolute or dissolution certificate to update your name.
   • Provide the relevant certificate along with the application forms to change name after marriage on passport and driving licence.

5. Change of Name by Usage:

   • If you have been using a new name consistently and can provide evidence, you may be able to update your name on your passport and driving licence.
   • Submit supporting evidence of your consistent use of the new name, along with the required application forms.

6. Change of Name for Gender Recognition:

   • If you have legally changed your gender, you can update your name on your passport and driving licence through the Gender Recognition Certificate process.
   • Provide the Gender Recognition Certificate along with the application forms to update your name.

Always check with the specific authorities responsible for passports and driving licences for the most up-to-date information and requirements. Keep in mind that there may be fees associated with these processes, and processing times can vary.
