CMS found ex-partner’s undeclared income after years of no child maintenance

I split from my partner 2 years ago. It wasn’t an amicable split, he cheated and was evil and enjoyed rubbing my nose in it like it was me who did the dirty. He’s a narcissist!
We have 2 children together and even though he has always earned well, he would never help financially with the children.
I contacted the child maintenance service and for 2 years I was told he didn’t have to pay anything for his children as he was claiming benefits. ( he’s never been on benefits)
Yet he was still working for the same company that he’s been with for years and driving the same company van as well as owning his own home and income from a rental property.
He would happily smirk and say ‘they can’t touch me, I’m on benefits’
I asked the cms to look into his earnings, which they did and found out that for the last 2 years his income has been nearly 50k a year.
The cms are now recalculating and he’s not as ‘cocky’ as before.
Im awaiting the new calculation but have had hundreds of messages asking me to drop the claim as ‘this is what civil mothers do’ lol, he’s been anything but civil since the split.
He now wants to come to set up a private arrangement ( he doesn’t want to part with any cash) but has said that he can help with school uniforms or take one of the children out for meals occasionally to ‘help financially’ what a joke!
His lifestyle is has never reflected a ‘benefits ‘ income but now the cms have obtained his earnings from HMRC, he’s getting worried!
Has anyone been in this situation and what can I expect after them discovering his income! Surely they won’t come back with ‘zero to pay’. I don’t want to get my hopes up!

If he is still “ bedding” he is worried he’s going to have to part with money

id be tempted to reply

CMS. They are a woefully inadequate government office who don’t know their arse from their elbow. if you didn’t pay voluntarily they add 20% charge and take directly from wages. CMS can’t touch you though, you’ve already made this very clear, so you’ve nothing to worry about 🤷‍♀️ karma will have to find another arse to bite

Surely he will have back pay what he owes and face legal consequences for lying for his benefits

Ignore his moaning and let the CMS do their thing. He had his chance.

Well done. Hopefully it will be worth the wait.
Is he still contacting you wanting a private deal?

Imbusytodaysorry · 28/09/2026 08:31

@littlebub11 hopefuly he will
be paying by Xmas. I’d call weekly it’s the only way to get them moving along . He will have to pay you 20% of his income and more for the arrears so no wonder he is annoyed . Maybe he should have paid for his children . Men like this make me sick.
You and your kids deserve this . Glad you’re not backing down .

Do not agree private arrangement. Let CMS enforce it. And for anyone who thinks its not worth making an application this is why you have to get your application. You just never know!!

Good for you, don't ever go for a private arrangement though. Leave CMS to get on with it.

I would also set up a nee email address solely for sharing information about the kids e.g access arrangements. Then block his number from all your devices, don't engage with him except for things relating to access. That way you have absolute control over him contacting you as you only need to check that mailbox e.g once a week.

@Notquitethetruth. Ive cut him off and there hasnt been any contact since July.

Good for you and well done CMS. Obviously he can't be trusted to uphold any type of private arrangement. They need to take it straight from his bank and hand it to you.

Thanks everyone for the good advice. I’m still having begging texts, saying I will get my karma for trying to ‘ruin him’ so I’m taking that as a threat. I’ve installed a ring doorbell for security and keeping all his texts as evidence. Still not heard anything from the cms, they seem to be taking forever. Will update with any news, be it good or bad!
