When a woman marries, her last name does not automatically change to that of her spouse. Your name will be the same even after marriage if nothing is done. The following guidance is valid regardless of whether a woman marries a man or another woman in a same-sex marriage if she desires to change her name after marriage.
Keep your name but change
your title
If you want to keep your
maiden name after marriage but change your title to Mrs. or Ms., for instance,
you don't need a deed poll. Not even a
new passport is necessary. In reality,
social titles are not recorded in passports. If you marry into the aristocracy,
a deed poll is not necessary, but you will need to change your passport because
it is thought of as a part of your name.
If you want to change
your last name to that of your partner, a deed poll is not necessary. If both your maiden name and the last name of
your spouse are listed on the marriage certificate, that document alone will
suffice as proof of your name change. Remember that only the original or a
certified copy of your marriage certificate will be accepted by organizations
like the Passport Office.
Your maiden name should
still be used professionally
