Recently a court ruled on a new order reducing my child support and ruled any arreages were free and clear. The local Texas Attorney General's office created a lien on these cleared arreages. They then withdrew the lien, and submitted a judgement on these arreages asking me to sign this judgement. This is termed as a supplement to the agreed court order. Can the local Texas AG legally require me to sign a judgement on an amount that has already been paid and ruled as "cleared" by the court? If not, what is my recourse with this local AG office?

Typically in Texas that happens because the counties got their wires crossed. (At least this has been my personal experience dealing with the court system.)

I do not know for sure if they can do this to you, but I would suggest taking your paperwork to the AG that shows the court ruling and cleared lien. Hopefully that can solve your issue. Good Luck!
