To ask how to resolve this!

Agree with PPs, send their Sunday clothes and no uniform. Tell him to use what he's got. Also can you ask the 8 yo to have a root around in his house and track it down? Then they can give it to him to wash. Not ideal buy at least then you can prove he had it and couldn't be arsed rather than it genuinely being lost.

Can you ask the school if DC could change once they arrive at school as your ex is using this situation to harass you. That way the PE kit stays in school.

If its not at yours, it must be at his. So don't send them with any this Sunday. He can explain monday morning.

so he’s got a PE kit for each of them and a uniform? Send them on a Sunday in just normal clothes and he keeps what he has got there. He can use that every Monday and Tuesday and wash in between.
you buy a uniform and PE kit to keep at your house and don’t let it out of your house.
if dads uniform comes to you on the Tuesday night then you can wash and give back the next Sunday if it doesn’t you don’t. Your PE kit never needs to go to his snd his PE kit never needs to go to yours

I don’t understand, are you saying he keeps the uniform and sells it on the side or something? Otherwise why don’t you just exchange it at the next drop off?

And what do you mean he has no washing facilities? Does he buy new clothes all the time rather than wash his own?

Very strange.

FWIW, I do parent a child with my ex, and there’s always some frictional uniform losses (not least kids losing things at school), and clothes get mixed up with my clothes and put away in wrong place, etc. You definitely need more uniform to deal with that, but it’s not a bottomless pit.

We share clothes for SS across houses as they are effectively his so he comes and goes in what he pleases now he is almost 14. However I will sometimes find my stock depleted and have to ask his mum for a few trackies back and bits and she’ll bag them up for me. Can you not ask him to put all school items in a bag for the next time you collect/he returns them??

That being said we both send him with clean items so we both do the relevant care of said items.

Ahh, just read your updates, what a d*ck. Yes, send them in normal clothes and leave him to it!

Honestly I would do whatever it took to not let them stay at all. I couldn't bear the idea of them turning up for school looking really scruffy. I couldn't stand losing everything I bought because of him. If you stop them staying overnight do you think he would take you to court?

Don't send any uniform with them.when they go. Just the clothes they are wearing, seeing as he has loads of their uniform at his house

I agree with pp, send them in their normal clothes Sunday and tell him that he will have to use the uniform and p.e. kit that he is hoarding at his house. He can take them to his sister's to wash too. If he complains, tell him you can't afford to keep buying uniform that disappears so he will have to buy more if he can't return it to you. If things don't improve, I would offer Friday to Sunday EOW and tell him to take it to court otherwise.

I’d just go back to court and have it mandated that he either provides the uniform, sends yours back or pays you for it. Or he has them Friday-Sunday.

Fuck running around talking to school and trying to make sure everyone else is on the ball because he is a twat.

If he can take his washing to his sisters he can throw in the kids stuff as well. He’s just at it and playing a game with you. Stop it now - give him no more school uniform. As pp, he will have to answer to the school when you tell them he has DC from Sunday to Tuesday and it’s nothing to do with you.

I’d speak to the school and see if you can provide school unifoms/pe kit to them directly and they change clothes there, and you pick up the dirty kit to wash and re provide. The same for coats etc. you can’t keep buying for him. If they say no, then he doesn’t get to see them during the week and no over nighters, clean clothes is a basic human need

Does he pay you CMS?

As @Pineapplewaves said, send them on Sunday with just the clothes they are wearing, nothing else.
He obviously has loads of clothes at his house. If he can't manage to find them the right uniforms for Monday and Tuesday, he will have to explain it to the school when he drops them off.

”Ex doesn’t have any washing facilities” so how does he wash his own clothes then? Send them to their Dad’s on Sunday wearing their Sunday clothes. Don’t give him any school clothes. He obviously has plenty already at his house so he can 1) go to the launderette or 2) go to the supermarket and buy them what they need or 3) return the children to you and he doesn’t have them overnight.

Sounds like he wants to cause as much hassle for you as possible.
So you need to talk to the school and find a work around that removes his power.
Or go to court re custody arrangements and ask the court to tell him to pack it the fuck in.

Or stop them staying with him when they have school the next day.

Tell the dickhead that he sends them back to you in full uniform, or you’ll go back to court and either ask for weekend only access or you’ll ask for enough maintenance from him for a full school uniform to be purchased every week.

What is he sending them to school in on Tuesday though? If they’re not in full uniform at school could you explain what’s happening and ask the school family liaison officer to have a word with him?

(In the short term school probably have loads of second hand uniform they’d be happy to give/ sell to you).

Sounds like he's doing it to be spiteful then. Deliberate rather than benignly useless?

Can you talk to the school and explain the problem with him and ask if you can send pe kit in on Friday and collect it on Tuesday and have them go into school in their uniform and get changed. Your ex being a cunt is extenuating circumstances and maybe the school would want to help you.
