My ex had his employer (his dad), change his pay slips to show he had a reduced salary so he didnt have to pay the correct child maintenance. he receives the difference as cash in hand! CSA arent interested in investigating. My ex has now rented out his house and moved in with a lady and her two children. So in theory he has now possibly reduced his outgoings? His new lady works at a very highly paid job and is also receiving child maintenance for her two children from her ex husband. Does anyone think this might mean the child payments he pays me should be looked at again? I would appreciate any replies.
