My question if I owe her 8K and I can only pay 2K at the time of the court date what then? Can I work out a payment plan to pay the rest off?
You'll need her cooperation on that. I would try to work out a payment plan with her BEFORE sniffing after her new job. If she knows you are looking into her new job, she might not be as willing to work with you.
How sad that you had to get lawyers and the courts involved in this. You owed the 30%. If you couldn't pay it, try to work it out with her directly. Now you'll not only pay the 30%, but you're paying a lawyer too. Doesn't make sense.
The Gov cannot give anything to anyone - that they have not first taken away from someone else.
