3 months ago I found out my ex wife got married so I filed request for order to terminate alimony and put child support back to reserve. I was paying $1500 per month, $600 is child support.

We have a court date in 2 weeks. Today, I was served with request for order to change her child support to maximum $900 according to guideline.

Guideline was made when she was a stay at home mom with $0 income and with me making $5k a month pre tax.

Now she has a job making $23 per hour, a husband and is now pregnant.

How do I best prepare myself for court date? What should I think about and collect now to bring to court?

I’m in California.
