Changing The Man's Name
There is of course no reason why your husband should not change his name to your maiden name upon marriage. If you plan on doing this, you simply continue using your maiden name after marriage. However, your husband will need to take additional steps to change his name.
Most simply, your husband can just start using his new name after your marriage. However, if he wishes to get all his records and documents changed without any problems or delays (for example, his passport and records such as income tax, national insurance, bank and building society accounts), he should execute a change of name by Deed Poll (see footnote below).
