Long story short but without drip feeding, I have 2 children with my ex boyfriend. We never married, we’ve split 5 years ago and in that time he has married the other woman and has 2 children with her. My children have his surname, as does his wife and his two children with her. It hurts me that she shares the same surname as my children but I never will.

aibu to use my surname for my children? For context dad is not in the picture anymore and has very very limited contact.

I think in your position I would change my surname to theirs. You would just be taking your children's name, not your ex's.

Just change it.

I've never understood this archaic practice of giving children mens' surnames. Why?

Oh but his name is so interesting and mine is so boring! His name just sounds better with my first name! 🙄

Why are you even asking? Change change change.shouldnt have had his name in the first place.

That's really a bit harsh lots of unmarried folk give children there fathers name without problems. And if married it's generally there fathers family name. came from olden times if you didn't have your fathers name you generally got nothing .so done to protect family line .

I’ve already socially changed their names as in they use my name themselves and for activities, non legal registrations and things. It’s more just legally I suppose. I definitely wouldn’t want to change my name to his and hers, it’s a small enough community and I think it would make me look silly to be honest given he married her but wouldn’t didn’t marry me

Just be aware that they don't end up with different names on things that need to line up.

My DN had a brief mare when he was scouted for a sport and his club records & registration were in his stepdads name whereas his birth certificate and ID were in his birth name.

If you take it to court they'd likely allow you to double barrel the surnames.

If your ex doesn’t have parental responsibility then you can do as you like. Personally I wouldn’t be changing it because of how I felt about it. Only change it if it’s something the children themselves would like.

Define archaic. It was almost universal until about 30 years ago.

You do not have to change their name legally at this stage. Just use a “known as” name for the GPs and school. When they are 16 change by deed poll and catch everything up then.
I did this with my DD who was born just after the law change in 2003 which meant I couldn’t change it legally without Dickhead’s permission. The only thing she had to put up with was her passport has to be in legal name but she was okay with that. We did deed poll on her 16th birthday and applied for bank accounts, driving license and everything else after with no issues and her latest passport has her new name too.

This is the easiest and simplest way to do it.

this seems like the best option (after asking him first, obviously him agreeing is the easiest option & he might surprise you, he might be fine with it).
