CSA preventing my son from having a future

Im self employed they have got my figuers completly wrong,even thuogh they are with DWP/hmrc(TAX OFFICE).

They have put court orders on my house,but i want to pass the house on to my son so he can have a future . they (don’t care)and i also found out from a judge that the money you give to the person taking care of the child, they can do what they like with the money and nobody questions where the money goes.

I found out that the money i was paying into the account was proping up an overdraft.it seems the only person my ex care about is herself,some future my sons got.
