Why is this important?
Anyone over the age of 16 can change their name at any time. You can change either your forename, your surname or both. You can add new names or drop a name you do not want. You can use your new name for all purposes including getting married or applying for a passport. You can not change your name for purposes of fraud.
You do not have to fill in any forms or get permission. You just start using your changed name instead of your old one. However, you may find that some organisations want to see written evidence of your name change. This could be a letter from a doctor, priest or solicitor, or an announcement in the press. You may prefer to make a statutory declaration or change your name by deed poll.
