I know there is no law. 
I am just saying, and I will say it until I drop dead, that it is an unfair hangover from the bloody ice age that a woman, upon marrying, still (usually) thinks that it is loving, nice, traditional and all that other crap, to take her husbands surname.
Many other cultures dont have such a stupid tradition.
And married people should never have a joint account.
Even Vincent Duggleby told me that. Rather despairingly!
We are meant to be living in an age of equality.
Yes yes I know this argument has many facets but a woman should nvere take her husbands name and a childs surname should be barrelled and barrelled and barrelled infinitum.
If native indians do it so can modern westerners
We are just hung up on bloody 'paternity'
Its the mother that usually gets the dcs. So why should not husbands always take the wife's surname? Then, upon the split, the dcs would have the mother's name.
Come ohn, you can't say that's not fair...because that is how it is at the moment for men.
