Sorry, more bad news, madam.
If it wasn't court ordered, it wasn't child support.
What was it?
Well, the court would consider it to be a gift.
If it was a gift, it's revocable.
That means, the deadbeat giveth, the deadbeat taketh.
Bottom line, he was never mandated to pay child support to you.
He bamboozled you about that, and he's bested you again!
When you discovered your minor child involved with an adult, male, pervert; and failed to report the molester to the police (taking the child to the home of the deadbeat), another bad move!!!!!!
