Maybe the burden is on him for not having proof of having paid money?

If the burden is on you to request the money, repeatedly, then send him a certified (return receipt requested) letter asking for the monies to be paid. Keep copies and copies of your postal receipts, etc.

Who is enforcing this court order?
Has your mother reported this refusal to pay to the court?

I understand why you try to help; it just sounds like you are spinning your tires AND getting hurt.
