We discussed both options.
we decided on his for a variety of reasons:
he already had children, and the divorce/power his ex had against him with the children made it clear that a man would find it much more difficult dealing with schools/gp’s etc with a different name. He was already having to carry legal documentation to “prove” he had parental responsibility, school wouldn’t talk to him without his ex, neither would the GP. His ex trying to change his kids name’s to her OM’s broke him.
holidays, hotels, basic life if ever he needed to do anything without me, if I couldn’t go. A 50 year old “Mr Smith” booking a hotel room or trying to leave the country with 15 year old “Jane jones” is a call to the police.
it was the right decision for us. My relationship with my kids has never been questioned, despite having a different name. There are many occasions when his would have been- the assumption is step father where the child’s name is different.
it’s nothing to do with my feminism, but more recognising females/mums have a lot more power and credibility than dads, and them having his surname recognises his responsibilities. If we split it would be 99.9% certain the kids would remain with me, purely because I’m female.
as it is my kids have a second nationality on my side, and my family name is instantly recognisable as that nationality. So my name features strongly in their heritage anyway and they recognise it when they’re asked how come they have two passports.
i know many women change their names and name their kids purely for traditional/patriarchy/want to show how proud I am to be married, but that is not why I did it. That would have been pretty much the only reason not to, tbh.
