To want to change my children’s surname?

VP2024 · 07/01/2026 18:29

For context, my children are 8 and 2, I split up with my children’s father, we were never married. It has been extremely rocky and stressful as he has prioritised his new life with her, instead of being consistently there for the children.

There was a conversation where he hinted marriage might be on the cards - it was brought up because my eldest apparently asked him if he would marry his new girlfriend.

Anyway, it got me thinking, it would make me feel really uncomfortable that maybe in the future, his new partner and him would share the same surname as my children, but I wouldn’t.

I want to approach him about changing their surnames to mine or potentially double barelled but they have quite long names already. My preference would be that they had mine as I am the primary carer (he literally sees them a couple of times a month for the day if that).

AIBU?

To you, that name is tgeir dad's name and his new wife soon (assuming she even wants to take his name). But to your kid, it is THEIR name, at least your eldest. It's their persona, who they are.

Unless they have no contact at all, changing their name only has the purpose to suit you.

My mum did exactly that when I was 6 or 7. I hated it and resented her for it. Thankfully, she didn't change it legally, so when I was 15, I owned it again and at 50, it is still my name. I didn't even take my husband name. My kids have their father's surname even though we separated when my eldest was 4yo. I don't see it at their dad's surname but their own.

I don’t think it’s fair to make an assumption that it didn’t matter enough to me. When my children were born, particularly my first, I was in love and I genuinely thought we would always be together and get married. It wasn’t a decision based on the norm of children having their father’s surname. Trust me, I only left when I had absolutely nothing left - it hasn’t been easy.

The issue is it has only been in recent years that children have been given their father's surname in your circumstances.

The norm was that children had their mother's surname.

I didn't change my name when I got married many years ago, DC have double barrelled names.

Genuine non snarky question, but what complications would that cause for them as kids?

I’m guessing the first passport update post name change might be a trickier but curious as to what the aggro would be beyond that.

I am however of the mind that OP should just leave her kids names as they are though because in the grand scheme of things, does it really matter? Anyone that knows them will know the set up and know they’re not the new partners kids. Although a double barrel is a reasonable compromise.

It is mostly an issue if the person enters a career that requires background checks.

BeMellowAquaSquid · 07/01/2026 20:04

And if/when you remarry would you change it again or expect your new husband who may already have children with his name change to yours? Double-barrel sounds the most obvious choice irrespective of length.

I’d definitely want my children to have my surname in some way or another. Could you give them your surname as a middle name, or double barrel your name?

I would definitely consider doing a double barrell. They both have two middle names already.

I’m not sure if it is petty though.

It is petty though. You're not doing it because you think it's in their best interests, you're doing it because you want to make a point to your ex.

I also question involving your child in this discussion she's obviously going to say what she thinks you want to hear because she's 8 and already knows you and daddy don't get on.

Edited

She doesn’t know we don’t get on in the sense that I’ve never spoken negatively about him in front of her and I am always very positive about him even when he hasn’t deserved it.

Ive also never been negative about the new partner when she has come home from spending some time with them (he introduced them very quickly against my wishes).

I suppose she knows we don’t get on because we have obviously split up so I understand your point from that perspective.

This is why traditionally children were given their mother’s name. I have no idea why so many unmarried women have started giving their kids the father’s name.

Having a name that is different than the one listed on your birth certificate adds complications. If an adult wants to deal with that hassle, that is their prerogative. A lifetime of dealing with the resulting problems is not something that should be imposed on children just because the parents are unhappy with their own life choices.

I actually have a name different to that listed on my birth certificate, changed via deed poll. It hasn’t caused me any complications.

I’m not sure if it is petty though.

They are with me 95% of the time (not through my lack of trying to make sure he has a relationship with them), he has openly admitted to prioritising her over his children and I think if he’s going to continue like this and not be a fully present co parent then why wouldn’t I want to have the same surname as my children? When I will be the one having sole care of them for the majority? Holidays, travel etc.

I understand the decision I made when they were born and yes maybe I was silly to have given them his surname when we weren’t married, but even if we were if the ending had been the same as it has been then really the situation isn’t any different.

There's a boy in one of my DC's year at high school who has had two surname changes. He's 15 now! Really so unnecessary and effs up their identity. Think about that. Your name is what makes us who we are, part of our identity.

Your post talks about what you want but doesn't give any consideration to what your children want. How do they feel about their names being changed?

I consider my children in all of my decisions - if it was something I ended up deciding I’d want to discuss with their father, I would also do the same with my eldest (8yo) and make sure she had all the time she wanted to consider, I also wouldn’t do anything she didn’t want - however much it bothered me. My 2yo obviously is a different situation considering her age.

I wonder if OP felt a bit forced into giving the children their father's name. They needed a family name. She could not register their births without one. Their father may have refused to agree to anything but his name. As they were not married, he had to be present when their births were registered in order for them to have a father's name entered on to the certificate. If they already have very long names she may have worried that a double barrelled name would cause them problems with form filling, and situations when they needed to use their whole registered name.

ForMyNextTrickIWillMakeThisVodkaDisappear · 07/01/2026 19:30

I understand why you want to do this but he probably won’t agree to it and he has to.

As at least one person has already suggested, would you consider changing your surname to theirs? No shade if you wouldn’t btw, I thought about it myself but ultimately chose not to as I wanted the same surname as my kids but didn’t want the same as my abusive ex.

OneNewEagle · 07/01/2026 19:29

Yabu

if you cared that much they’d have had your surname when born, as mine does. This is about a new girlfriend.

Wasn't it? So why didn't they have your surname then? The 'thought we'd be together forever' bit makes no difference. Everyone thinks that.

I'm sorry you've had a rough time in the relationship but this aspect of things doesn't make sense.

AnneElliott · 07/01/2026 19:26

YourZippyHare · 07/01/2026 18:49

If he refuses, change yours to his. That'll piss him and his new wife off, probably, but oh well.

One of my friends was told by her ex that she’d have to change her name back once they were divorced. She was happy to as long as he agreed the kids could change theirs as well. Obviously he sad no and he’s furious that she’s still Smith for example as is his new wife (they’ve also got a relatively common name anyway).

Everydayimhuffling · 07/01/2026 19:24

At 8 and 12 it should definitely be their decision. I would only do it if they wanted to without any pushing from you.

SelfRaisingFlour · 07/01/2026 19:04

The children are too old for a name change just to make you feel more comfortable about the new girlfriend. They have had enough disruption with having a part time father.
Would you give them a say in the decision? I doubt your ex would agree.

Yes absolutely, if it’s something I would discuss with the father I would also discuss with my 8yo and see how she felt about it and give it a good amount of time to see how she really felt about it. I would never do anything to make her upset or feel like I was cutting her dad out of her life, if that’s how it came across to her.
