Reasons why you might wish to change your name by deed poll
You do not need to have any kind of official reason to change your name, so long as it is not for any fraudulent purpose, such as avoiding paying a debt or fulfilling a contracural obligation. you are in fact free to change your name at any time and any number of times. Some typical reasons people change their name are:
if you get married or enter into a civil partnership, or you want to take your partner’s name
if you get divorced or dissolve a civil partnership, or end a long-term relationship
to take a double-barrelled name after you marry, or enter into a civil partnership
To have the same name as your babies father for unmarried couples
to feel more part of a new family, for example a step-family
to revert to a family surname that has been changed in the past
as part of a change of gender
because you dislike your current name
to separate yourself from a particular person or a time or event in your life
to try and stop a former partner finding you on the electoral register or on social media sites such as Facebook
to make your foreign name easier to understand
to identify with or fit in with another culture, country, or religion
to change the spelling of your name
Changing your name for fun or commercial gain
Some changes of name, while not illegal, may be considered by HM Passport Office (formerly the Identity & Passport Service) or other government bodies to be for a silly purpose. This means that although these bodies may accept your change of name, they may require additional evidence that you are using the new name for all purposes not just as a publicity stunt.
Your change of name may be considered frivolous if it seems that you are:
changing your name for a bet or a laugh
changing your name on a whim
changing your name for purely fun reasons
changing your name for purely commercial gain such as Maria Sharipova changing her name to Sugarpova
changing your name at the same time as a group of other people for a joint purpose such as an entire football team
