So, what I hear you saying is Guru was right?

I'm not tooting my own horn, I'm just hoping others learn from your experience. Attorneys will drag their feet every time if it will help them win. Every single criminal attorney will continue a case several times because witnesses move or forget or get lost in the shuffle. In this case, they wanted to wait for you to get a job.
There is actually a section of the guidelines that addresses parents who attempt to hide income or not disclose it. I think it's called "failure to disclose." Essentially, the rule makes you impute your income back to the day you got your new job. So if it's October when they figure it out and you go back to court, they would rule that your income changed in May, so you'll then owe the difference.
I can't really give you advice, but what here's what I would do.
- Do not provide a thing before the hearing.
- Go to the court transcriptionist and get a transcription of the hearing which determined that your CS payment was reduced. Hopefully it was requested to set it retroactive back to the day you lost your job. There is a statute that CS changes are effective the first day of the month following the hearing - or something like that. You should double check that.
- During the hearing, you can mention that you just got a new job. They will probably attempt to calculate it on the fly during the hearing. Avoid that.
- You should ask for a 3 week continuance to consult with counsel (have a date in mind). Whether you do or not is up to you. You can use eFamilyTools to calculate it and present that worksheet to make sure theirs is right. The point is you don't want them calculating it in the court room because you might get hosed. Remind them that regardless of the order they make on June 6, it will not be effective until July 1 by statute, so they should grant your continuance based on that.
- You absolutely want to make sure you get credit for the months you were not employed. That was the whole point of your motion and you have a ruling that CS would be reduced. So, make sure that all the math works out and shows that you should not have the same CS payment during those months.
- Advocate very strongly for yourself and filing a motion to reduce support because you didn't have income. If the circumstances were turned and your income increased, the other side would absolutely want to take credit for every single day you made the higher wage.
