I think I know the answer already but is there anything I can do about this, have children with ex, he doesn’t see them at all, no over nights no contact nothing (his choice) I opened a child maintenance claim when we split 5 years ago but it said he wasn’t working or claiming benefits so no maintenance payments, I know what he does, he has a 3 bed house and rents out all 3 rooms to lodgers whilst sleeping on his sofa, (he has admitted this to me) due to this child maintenance can’t do anything, I ended up closing the case last year as I was frustrated getting nothing and it just felt like it was being rubbed in my face (would constantly get letters saying he didn’t have to pay anything from cms) I did Keep it open initially in hopes that one day he would get a job but 5 years later and it never happened. Is there anything I can do about this? I put it into the calculator as he told me how much he gets and he should be paying £380 a month! I’m guessing I won’t get anywhere as I suspect it’s cash and I know he doesn’t declare the lodgers..
