DH stoping paying CMS

donewiththistakemeaway · 29/06/2026 10:25

My husband told his ex-partner — the mother of his two oldest children — a year ago that he planned to leave his job within the next 12 months. She has never worked, and for the last 9 years he has paid her £1,500 per month voluntarily, even though the Child Maintenance Service calculates the correct amount should only be around £300.

The kids stayed with us for 10 nights a month, matching my husband’s days off. Between us, we did all school runs, clubs, meals, and bedtime routines — returning them to their mother around 8pm each evening. They couldn’t stay more nights because my husband’s shift pattern meant leaving at 5pm, driving 2 hours, working until 7am, and getting home by 9am. This would have left me alone caring for all 5 children while also working, handling all household tasks, and managing their activities. Meanwhile, their mother only had to put them to bed around 9pm, yet received far more money than required. We also take all five children to their clubs and activities every weekend.

My husband has now left that job — he was exhausted, and after 12 years of hard work, my own business has become successful enough for me to be the main earner. He reminded his ex repeatedly over the year that this change was coming and that his income would no longer support those higher payments.

He explained that he is now available full-time: he can offer full custody, 50/50 shared care, or flexible arrangements — whatever works for the children. He will be there for school runs, sickness, doctors’ appointments, school events, and anything else they need. The only change is that he can no longer make those payments.

This has caused a huge reaction. She is angry, calling him names and saying she won’t be able to afford her home. He asked her to consider getting a job, or for her new partner to contribute financially ( he does not work either) but she has threatened to involve a solicitor — claiming that if my husband stops paying, I must cover the cost because I’m so flush.

I do not believe this is my responsibility. To keep things calm, I offered to pay the £500 per month which sis still more that what the CMS says is the correct amount, but this is still not enough for her. She won’t stop us seeing the children, as she only cares for them a few hours a day and enjoys having her evenings free with her partner.

My main worry is whether there is any legal loophole that would force my husband to keep paying that higher sum just to maintain her lifestyle?

Don’t pay her anything. If she can’t afford the children then they can stay with you like you offered. She’s an adult.

If you have 50/50 custody and your husband won't be working why would you even continue sending £500? At somepoint his children will be adults and the money would stop, she was always going to have to get a job and earn more. Buying her a house and paying all that money for years, plus having his children 1/3 of the time overnight plus school pickups and evenings I think you have carried this woman enough. I wouldn't even offer £500, sort 50/50 custody and go through CMS so it is clear he isn't earning so you can't be chased for money. I think the mum needs to step up, get a job to support her children and her partner also needs to work to contribute to the household.

I just told her I would pay the £500 just to keep the peace possibly a stupid mistake but I’ve said it now

This is the most unbelievable part of the thread! How you could marry and have children with a man who prioritises his ex wife so highly…

You gave her a year's notice. He now has no income. She doesn't actually look after her children. She's never worked. Her mortgage is paid off. The kids want to live with you. Have I got this right?
In which case, why on earth would you give her any money?

I agree - the key things are her not actually doing anything to look after the kids and the kids wanting to be with the OP.

The rest is almost by the by.

It’s up to her if she doesn’t want to work but she can’t expect everyone else to fit in with that plan. She’ll have to cut her cloth according to her means!

BinNightTonight · 29/06/2026 12:23

Not the point I know, but how could he afford £1500 a month if CMS saw his wage and said he is liable to pay £300. Wasnt that his entire wage?!

I think paying £1500 was extremely (too) generous and of course has to stop when your household is doing pretty much all of the childcare and providing all of the food, clubs, new clothes etc. If the children want to live with you full time, you'd be well within your right to get paid CB and to seek CMS from her.

I hope the house is still in your husbands name.

GertrudePerkinsPaperyThing · 29/06/2026 12:21

He and you seem to be doing all the parenting already from what I can see? As well as paying maintenance.

And the Mum just has certain overnights almost for the look of the thing!

Sounds like you need to have a fresh look at the whole set up. 16 and 14 are more than able to make their own decisions but also should be able to get about by themselves? Unless where you live is remote?

If she says she’ll talk to a solicitor just say fine and do the same! But honestly at 16 and 14 it’s up to them.

So SAHMs are morally wrong, even when their husband earns enough to amply support the household?

IMO if you are separated and your kids are teens or older there is no reason not to work.

ERthree · 29/06/2026 12:14

Of course but the decent thing to do is to offer something but as the children are fed and taken to clubs at their dads house then maybe it would be acceptable to stop all monies.

I'm not so sure. What is the mum doing to provide for her kids? They are not at an age where she can't work.

TealDoors · 29/06/2026 12:17

whatonearthishappenin · 29/06/2026 12:11

But we all want to spend more time with our children... it is usually the financial responsibilities we have that stops us. Your DH appears to have forgotten that he has financial responsibilities towards his children.

(As does their mother - but that does not mean your husband's just fall away).

Why? How come she doesn't offer them money when the kids don't do much more than sleep at the mothers house and they feed them and drive them around everywhere and wash all their clothes? Is it just because she's the mother and he's the father?

Dweetfidilove · 29/06/2026 12:16

As the kids primary residence is at yours and that's where they want to live, that's fine.

It sounds am almighty mess as usual, but I'm sure you'll figure out the nest outcome. Amd thankfully this jas happened at a time when the kids are old enough for the mother to source full-time employment.

YANBU for not paying yourself. YABU for enabling your DH in financially abandoning his children. No wonder she's angry.

You talk as if she is being abandoned, but she has a house paid off and a new partner. All they would need to do is both work part time, her ex has been overpaying the maintenance by law by £900 a month for years, he has been a responsible father.

ERthree · 29/06/2026 12:14

stargirl27 · 29/06/2026 11:08

The DH has no income so the CMS won't be telling him to pay anything.

This is unbelievable unless he is EXTREMELY wealthy... is it still legally in his name or did he transfer it to her?

This is a really key point. Does she legally own the house she lives in (ie he transferred ownership to her) or does he still own it and she lives there at his grace?

The OP has started a thread about her business 🤷‍♂️

You've missed my point.

Plenty of households have one working parent, as long as they can support themselves and their children then it doesn't matter how they arrange themselves.

Thank you for settling my mind. She said something about being eligible for legal aid for a solicitor so naturally I’ve started spiralling

She won’t be eligible for a legal aid solicitor. Legal aid doesn’t cover this sort of thing.

Don’t pay her anything beyond strict CMS liability, he’s been overpaying for years. She needs to get off her arse and get a job and support her kids like any normal adult needs to.

Yes, it's making me wonder why she doesn't just sell it tbh.

Unless it's not actually been put in her name.

He’s quit work so he can be there for all 5 children. Bit of a double standard going on if it’s fine for mothers or step mothers not to work but dads are expected to work. He wants to spend more time with his children, I don’t think that’s wrong

But we all want to spend more time with our children... it is usually the financial responsibilities we have that stops us. Your DH appears to have forgotten that he has financial responsibilities towards his children.

But he's fathered 5 kids and decided to put his feet up early.

The OP is working and supporting the household, just like he has done in the past. How they decide to split their childcare and financial responsibilities is their business.

They were together and had children and he paid it off with inheritance. 2 years later they broke up and he let her keep the house. There’s no thing for her to leave when the kids grow up.

Bang out of order, this guy paid off the mortgage before he left so she has no mortgage to pay, he has been paying her £1500 a month but all the kids do is sleep there, don't eat, shower, wash or socialise there. Why can't he do what she has been doing, at least he has contributed financially and why can't she or her partner get a job?

She is angry the gravy train is ending and she has to face reality.

fuck her don’t pay a penny you and husband are doing a great job with the kids. She’s just a money grabbing bleep
