Jailed for overpaying child support after agreement secretly modified without notifying the father?

I've sort of adjusting to viewing family courts as a travesty of justice, but this case seems to take the cake. Take a look at this man's case:

Last November, his child support payments were paid in full. Sometime between then and now, the child support agreement between Hall and his wife was modified without his knowledge. Hall wound up overpaying by $3,000, a fact that Harris County District Court Judge Lisa Millard found contemptible. Another term that was modified without his knowledge was his visitation schedule. Subsequently, Hall was found to have over-visited his son. Judge Millard ended up finding Hall in contempt of court.

It seems to me that you'd have to be a pretty despicable individual not to be in contempt of this particular court.
