I think ultimately it's personal choice but that you really should think about it, properly, and not just change because that's what people do.
For me, no way. A) it's my name. B) no one is expecting men to do any name changing, so why the fuck should I do all the hard paperwork and emotional labour of getting Jeff to a new name? C) I have professional reputation bound in my name. D) no one is expecting my husband to change his, and he wouldn't even contemplate it, so no chance I'm doing it.
For the record, I wanted everyone, DH included, to have both our names, but he just wouldn't, said he couldn't be bothered, so I'm keeping just mine. Our children will either have my name or be double barrelled.
Double barrelled is most likely but if not then they'll just have mine, it's up to DH - the double barrelling is a nice compromise and if he only wants them to have one name they'll have mine.
I can't stand unfairness and it's unfair to expect women to always be the ones to flex on this.
