An increasing number of women are keeping their own surnames as their is no legal obligation at all in Britain for any woman to change her name on marriage.
Some people think that they should have children registered in the fathers name but this again is an old fashioned tradition as there is no reason at all why children should not take their mothers surname. In Scotland and Wales and Ireland girls often kept their own names after marriage or gave their children both mother and father's surnames.
Some couples use both surnames as a 'double - barrelled' name.
If anyone wishes to incorporate both surnames to make a new surname they can have this made official by deed-poll.
Many professional women retain their own names.
