NC as potentially outing. Sorry its long (Also posting for traffic, not an AIBU, sorry)
I will try to give a back story so as not to drip feed. DH divorced ExW roughly 2 years ago, but didn't obtain a clean break order. He has a child with ExW, who she has moved away and stopped him seeing, long story but he is doing what he can to get access. ExW left DH 9 years ago when their DS was about 3, initially left children (he has a step son) with him. As she doesn't work and he does, it was agreed she would have son living with her, and DHs SS chose to live with his dad as didn't want to live with his mum. DH was visiting both children regularly, paying maintenance, clothing and feeding children when he had them etc. Then ExW moved 200 miles away. DH followed & moved nearby to see his son, visits every other weekend etc. One day he turned up to see son and SS who was visiting ExW, and the house had been moved out of, with no notice or forwarding address to DH. DH still gets on with EXInlaws, who are helping him with the access and new address.
DH was paying a set, agreed amount each month. ExW decided she could get more money through official routes, so informed CSA, who did get her more money. As ExW didn't/doesn't work, they informed her income support people, who deducted money from her, so she ended up with less than she initially was before CSA involvement (sorry, im not very good with official/technical terms). ExW and DH agreed to cancel CSA involvement, and he paid her monthly bank transfers again. When ExW moved away without informing DH and stopped him seeing his son, DH stopped paying maintenance, and saved money into an account for DS for when he is older.
DH is now looking into a Clean Break Order, but is concerned ExW will get CSA involved again. He's not worried about paying for his child, but knows from previous instances that ExW spends the money on herself instead of clothing son, so wants to make sure the money goes to son and not ExW (he does understand maintenance is for housing on top of other things for child), hence the bank account for son (who is 12).
If he gets a clean break order, after already cancelling CSA (or whatever they call themselves these days), can she reapply for it?
ExW left DH with £30k+ debt, as it was in both names and she doesn't earn money, he is paying it off. Debt was for things she managed to get in joint name after leaving DH, but before he separated accounts etc., so he understandably doesn't want to give her anymore money for herself if he can help it. DH wants to do the Clean Break order without involving solicitors if he can help it, so any experience or advice would be greatly appreciated.
