What is he playing at ?

Don't know if this was the right place to post this , basically i have been divorced a yr today hoorah, even though finances have not been sorted due to him delaying everything , but he managed to get a judge to give him the absolute.Where do i start right last June i was notified by the CSA that he had relevant other children in his household so my children's maintenance was reduced not that he has been paying anyway.Then his form E comes stamped from the court last Sept in the box are you co- habiting he ticked no, my sol informed CSA of this and his previous assessment was put back in place , his parents have collected my children this morning and his mother informed me there had been a letter form IR regarding over payment of child Tax credits to him and his partner , I just don't know what is going on , i know currently he pays £80 p/w rent for a room in a house but spends all his time at her's and she is claiming as a lone parent, just can't get my head round what is he playing at.Is it because if he put's he is living with her her details will get bought up , i'm no good with the finicial side of things.

if he is living with her report it to the council dept who pay her rent, they will have to pay everything back theyve had 0800 838223 benfit fraud line. this is my next port of call once the FH is over

I have to agree. If he is messing you about, play it by the book. inform the appropriate authorities (through your solicitor if you prefer) of any situations which are different from what they claim.

Benefit fraud is a big deal, from what I understand. Maybe with a conviction for that against him, it would be easier for you to get some money out of him?
