To think that must be something I can regarding CM

[SouthernNorthernGirl]

My ex and I have a teenager together. We split many years ago, and I've been with my DH for 11 years now.
He stopped paying any money around 9 years ago. I went to CMS in the end, and they did an assessment. Since then they've sent me letters telling me he doesn't have to pay anything, and last year they sent a final letter, saying that they were closing my case and to get back in touch if his circumstances change.
He owns his own business, and I just don't understand how I'm supposed to know anything new. I'm not even sure how they came to that conclusion (that he isn't responsible for any costs) in the first place.
He refuses to support DS, and I've long given up asking as he's just verbally abusive.
He sees DS every other weekend when he can be bothered and I've had enough now.

Is there something I'm missing that I could do about this?

This is exactly the same situation my poor DM was in with my father. Courts were a game to him; he ran several business, drove around in a Porshe, yet somehow managed to pursude the courts he was broke. When my DM went to court to get help with childcare so he could work, he suggested that his girlfriend (who my mother had never met) could provide childcare and made the courts believe my DM was being unreasonable when she objected. She objected, because she knew that the arrangement would never last and she would then be left with all the childcare costs. Which, of course, she was after a few weeks.

I'm NC with my father now. It was the best decision I ever made to have him out of my life.

Sorry, help with childcare do SHE could work...

It makes me so frustrated, especially since it seems not an unusual situation. Already both posters that replied have known someone do the same thing.
Surely CSA need to see proof of earnings etc? How does he get away with it?
I'm positive it's a crime in the USA, and other countries. Why are the UK so blase about it?

Why are the UK so blase about it

I don't know and would love a party brave enough to change things. Both the RP and NRP should be financially supporting the child/children they chose to have regardless of if the relationship breaks down.

However it's seen as fine by millions not to and benefits are very generous so the current system encourages it.

its wrong and immoral but there could be uproar if a party made it illegal to not financially support a child as look at the outrage from people when UC came in or when TC were capped to two children etc.
