My ex & I separated 13 months ago, we weren’t married & have 1 child together. I have asked him to sort maintenance privately which he was fine with & paid £300 a month however it was sporadic so I thought it best to go through official lines so CMS..he is a Director of a a Ltd company & draws down no dividends, wages or shares so now DWP have told me that he can pay zero. I asked DWP to check his Ltd company as he earns a lot of money but because there is no individual tax payment they cannot pursue it as a Ltd company is an individual tax entity so cannot do anything about it. I explained this to him & he said oh well maybe you should have been happy before..can I do anything?
