a. Plaintiff was unemployed when Judgment of Divorce was entered; Plaintiff is now earning in the excess of 28,000.00 per year.
Let's start with some basic facts:
1. What date was the judgment of divorce entered? It should have this date on the final divorce papers.
2. What date did you start working part time?
3. What date did you start working full time?
As I see it, you've got a weak case:
A. If you were working (even part time) before the date of the judgment of divorce, then you could be looking at a contempt charge for not notifying the court that you were working (talking about it with your ex isn't sufficient).
B. If you were NOT working before the date of judgment, then it IS a change of circumstances and ex can certainly ask for modification
So please fill in the dates and let's see where it goes.
