Just wondering if anyone has any experience in dealing with Financial investigation through the CSA? My ex partner has decided to retire early at 56 and before then had an income of over 170k PA, although he underpaid me ( not by loads ) he did pay every month, he's now refusing to pay anything towards our child, I have our child 90% of the time, I know for a fact he has a sizeable pension, assets and investments etc. He's managed to convince the CSA he has zero income. He's refusing to even help with our child's clothing/clubs etc unless I drop the case, if I drop the case he will pay me a tiny bit that he's 'worked out' not sure how he's worked it out with a zero income ?! I've been rejected 3 times with CSA and numerous variation forms etc. Now it's apparently been passed onto FI but unsure how long or if they'll actually be able to help as I don't have a scrap of evidence ( although he's taking flying lessons?!) has anyone any experience?
