My partner and I are currently involved in a civil dispute with her ex with regards to joint debt they built up that he is now refusing to help pay. Basically he is claiming he can't pay it due to unemployment but they attended mediation during the split and it was agreed that even if he is unemployed he can still pay a moderate sum, I think it was 10 pounds a fortnight towards it. In the last year my partner has received five pounds in total. When she has confronted him he has claimed he is 'sorting it out' and then nothing has happened. We are now in the middle of a legal dispute over this and other matters. The part that really gets me is that we have been honest about our earnings and so are paying for our legal fees privately. He is however claiming legal aid despite living full time with his new partner who has a 30 grand a year job and we also know he is working and has been doing so for some time because the company he is working for accidentally called our flat to get in touch with him because he hadn't updated his number in 3 years. He is also claiming job seekers allowance of course... Obviously we have shopped him as a benefits cheat but that was months ago and so far nothing. Is there a way to report him for fraudulently claiming legal aid? Who would we call, his solicitor or ours?
