As I have said many times there is NO LAW in UK that a woman must change her name on marriage. In fact, there NO LAW, which says, she CAN or even should. It is merely convention / practice and smacks of the idea that a wife belongs to her husband!
There is no reason why a woman upon marriage should not keep her name and have everything issued in that name.
If I were a woman, I would not change my name, on marriage
My wife wanted to change her name but we compromised so now she had a hyphenated surname, her maiden name and my surname.
All we did was go to the Philippine in Madrid and they made a manuscript alteration. I cannot remember the cost but it was insignificant. She has since renewed her passport in Manila using the hyphenated surname.
I also repeat, that anyone can change their name in the UK under Common Law just by saying they are doing so. Deed Pole is often mistaken, people believing that it empowers one to make the change. That is not so. It is just a registration that one HAS CHANGED their name.
This means that a man can easily change his name to that of his wife if he chooses to do so.
In talking about changing one's name. Just for the record I did it in UK about 25 years ago, my passport, NI number, bank accounts, credit cards, D/L everything (except birth cert which cannot be changed) No problems.
