Terpe do you know something I don't ?
Surely a marred woman can keep her name forever with no obligation to take her husband's name ?
As I said, my wife has a different surname from me, are you saying if we went to live in UK, she would have to change her name ?
Is the info here now wrong :

How to change your name
If you wish to be known by a different name you can change your name at any time, provided you do not intend to deceive or defraud another person. There is no legal procedure to follow in order to change a name. You simply start using the new name. You can change your forename or surname, add names or rearrange your existing names.
Although there is no legal way to change a name, you may want evidence that you have changed your name (see under heading Evidence of change of name). However, you cannot change details on your birth certificate, except in limited circumstances.
There is more information on changing your name by deed poll on gov.uk
Once you have decided to change your name, you can use the new name for all purposes, for example, publishing marriage bans, legal proceedings and obtaining, or changing details on a driving licence or passport.:-
