Ex has changed DC’s surname at school without telling me

I might be completely out of order here but I’ve found out my ex has changed the surname the school has for both DC and she didn’t tell me. I’m not talking about changing their actual birth certificates or anything like that, it’s what they are now listed as at school. I only found out because I picked DD up from after school club yesterday and noticed her coat label had a different surname on it.

DD is 8 and in Year 4 and DS is 6 and has just started Year 2. They have always had my surname, which is the surname they were born with and the one they’ve used everywhere. Me and their mum split up about 5 years ago. We don’t exactly get on brilliantly but I’d say we co-parent reasonably well. I see the kids regularly and there’s never been an issue with them having my name before now.

At first I thought the coat label was just wrong. Then I noticed the name on her school drawer was the same. I asked one of the staff at the club and she said they had them down under a double-barrelled surname now. I checked with the school this morning and apparently the database has been changed for both children.

Apparently they are now listed as my surname-mum’s surname, rather than just my surname. I haven’t signed anything or been asked about it. The school said their mum had contacted them and explained that the children were now known by both surnames. I’m not really angry about the double-barrel itself, which is probably the bit I need to make clear. If the kids genuinely wanted to have both names I wouldn’t be against that. It’s the fact I found out by seeing a coat label.

I spoke to my ex and she says the kids have actually been using the double barrel at her house for several months. She says DD especially likes having the same name as everyone at home because my ex has remarried and her husband has her surname. DD apparently said she wanted the same name as them. DS knows what it is but doesn’t seem anywhere near as bothered and apparently told his mum he’d rather just have his normal name. My ex says they both use the new name enough that the school needed to have the name they actually use.

I don’t want to put either of them in the middle of this or make them feel they have to pick my name over their mum’s.

My girlfriend thinks I’m getting hung up on the surname because it’s mine. She said if I’m honest about not objecting to double-barrelling then I should stop making it about me and ask the kids what they actually want. I can see her point. But there was an issue before with my ex and school forms where she filled something in without telling me, and I only found out when the school asked me about it. It was nothing major but I said at the time that we need to tell each other about things like that. She agreed at the time, so this has annoyed me more than the actual name change.

There is also a practical problem now because their medical and dental records, clubs and some other things still have just my surname. DD’s school photo order apparently had the double barrel on it but her swimming club has her old surname. DS’s football registration is still just my surname. So it’s not even simply that they have a new name and everyone gets on with it, because we now have two versions being used depending on where they are. My ex says this is exactly why she wanted the school to use the name they are known by at her house.

She keeps saying I’m making a massive issue out of a name and that I’m only bothered because it has my surname in it. I don’t think that’s fair. If she had told me beforehand and said DD wanted both names I probably would have had a conversation about it and maybe agreed. I’m not saying the children can never use her surname or that I own their names. I just think I should have been told before the school records were changed. Maybe I’m being unreasonable about that.

So AIBU to think the school should have contacted me before changing the surname they have for the children, or at least told me it was happening? I’m genuinely not sure what the normal thing is here. I don’t want to turn it into a massive fight with their mum over something the children seem fairly relaxed about, but equally I don’t want to just accept being left out of decisions about them. I might be completely out of order here and need someone to tell me that.

Bit different but my daughter has a double barrelled surname, for school ive dropped exes and shes known under mine only, never been questioned or asked for permission

I think potentially you might run into an issue if she's registered as Molly Smith and her BC says Molly Smith-Jones, if that continues into secondary and Molly Smith is what is used to resister for exams and on her certificates, and she then needs to supply proof of grades and it doesn't match her legal name they may not be accepted. I'm sure I've heard of that being a problem.

JLou08 · 30/09/2026 18:46

I can see why she didn't tell you. A long rant about not much at all when with your (what seems to be very sensible) GF having to try and rationalise this for you to manage your emotions.

Myfridgeiscool · 30/09/2026 18:48

School have done nothing wrong if the child wants to be ‘known as’ a different name. Legal name change would need an application to court. The kids can do that at 16 with no one’s permission needed.
Don't be dick OP. The kids just want to be part of both families.
You don’t own your kids, having your name doesn’t make them your property.

Why don't you just change the names properly so they can have the double barrelled name everywhere? It seems fairest, although traditionally children always had their mother's name if the parents were unmarried. They only had their father's name if the mother also had that name.

They only had their father's name if he would show up to register the baby as his. That is why illegitimate children were in their mother's name. The dad would deny the child. She would have desperately wanted him to claim their child! It wasn't female power or autonomy 😂

Batties · 30/09/2026 18:56

I assume you are on the birth certificates and have parental responsibility?

strictlybusinessuntildecember · 30/09/2026 19:02

My children’s school won’t double barrel unless it’s on the birth certificate for this very reason.

it’s a shame as I’d love to phase out my ex husbands surname completely for the children he barely sees and doesn’t pay for

imnotwhoyouthinkiam · 30/09/2026 17:19

Traditionally (and historically) children have their Mother's surname. But traditionally, the mother and father would be married and the mother would have changed her name.

Of course that's not always the way these days. But traditionally it is.

Not traditionally for me.

Women traditionally took their husbands name and the children took that name.

Partners - everyone I know took the fathers name.

Shes in a special school and won’t be taking GCSEs but can see why that would be a problem for others.

somanychristmaslights · 30/09/2026 19:07

How does how the school knows them cause any issues whatsoever with the doctors or swimming club? I’d say listen to your GF and not your male pride.

ScotiaLass · 30/09/2026 19:10

Your ex should have told you before she made this change with the school. However ultimately I think you need to respect what the children want, and if they want their name to be double-barrelled you have to support that to happen across the board. Insisting they go by your name because your ex didn't follow a decent process will backfire if this is actually important to the kids.

They are 8 & 6. That’s not old enough to be deciding on things like this and they shouldn’t be put in a position where they feel like they have to choose.

Icecreamisthebest · 30/09/2026 19:20

You say you don’t mind the double barrelling but the fact that the DC had your name only from birth indicates to me that perhaps this is actually a problem for you and the reason your ex didn’t tell you. Perhaps she wanted to do what the DC wanted without an argument with you and that is why she didn’t tell you.

I”d let her know you are aware and support the DC in feeling connected to both their parents and are happy to put their needs first so can she let you know what is needed to make it official. And that in future you’d appreciate a heads up if the DC want a change so that you can support them with that.

Traditionally as in in the past. So nothing to do with people you know/you.

My own DC had their fathers surname, we weren't married. We didnt follow the tradition. But I still know that traditionally they should have had my name. and wish they had

Tulipvase · 30/09/2026 19:24

You can absolutely have a preferred last name on the school system. Any legal documents such as certificates will have the legal name on them. At my school the legal name would be shown in brackets after the preferred name.

I know what the word traditionally means but thanks for explanation. 🙄

And since you are worried about my comment being traditional why did you give a recent example?

We don’t agree. There is no right or wrong.

Kids took dad name where I am from. You think differently. I don’t need to convince you.

FunPartyIdeas · 30/09/2026 20:07

@Itsbeenalongtimeincoming I really couldn't care less for the patriarchal traditions of children just taking father's last name or indeed women changing their name (and title) upon marriage.
My family are all db'd as both myself and my husband and I added on to our family name when we married. Our daughter is the same: MyFamilyName - DadFamilyName.

I explained shes in a special school and won’t be doing them.

DiscourteousDiana · 30/09/2026 20:43

I don’t disagree that children should have their mother’s surname. My DS has my surname. But this mum should have thought about this when she registered her children’s birth and chose to give them their dad’s surname on their birth certificates (and birth certificates can never be changed unless a child is adopted). If it had meant that much to her she should have chosen her surname for them then, not changed her name when she got married, or double barrelled their surnames. The right answer isn’t informally changing their known as names in school without any conversation with the other parent. How confusing for the children.

Fabank · 30/09/2026 20:42

Any legal certificate such as a GCSE certificate will have the child’s legal name.

Other certificates such as writer of the week, can say what you/they want.

My youngest was 3 when he started insisting that he be called his given name rather than the shortened version of it that we used and had asked everyone else to use. I think by 8 a child is definitely old enough to have a strong preference on something like this. I'm not suggesting that changing the name by deed poll is necessary at this point, but if they want to be known by a different name I think that should be respected.

Sunbringer · 01/10/2026 10:41

She’s probably sick of being called Mrs Your Surname

I don’t see an issue when it’s now both names. Your name is still there. Your girlfriend is right. She hasn’t removed anything, only added. It would have been polite to say so but do you have a history of kicking off at her?

PocketSand · 01/10/2026 16:06

I didn’t ‘take’ ex DHs surname when we married. When we had children they were given his surname. This caused problems at school. DH was assumed to be the biological parent and I was assumed to be his recent GF. I had to clarify to school staff that I was actually the biological mother. I still have to state that I am their mother due to not sharing their surname when dealing with officialdom. DC should share a surname with the resident parent for practical purposes. If parents have different surnames the DC should have double barrelled surnames.
