My ex decided to work part time two years ago to take care of a new kid she had with her boyfriend, who owns the house in which she lives now rent free.
So right off the bat, her income has been artificially lowered given her choice to live off her partner.

It took me 4 years to get primary custody of our kids. She was supposed to close her CS case against me but never did after that judgment. Now that I’ve filed to modify child support, the department of CS somehow calculated that she should owe me 700/month. However that got set to zero (??) because i “didn’t open my own child support case”. Even my lawyer was confused because usually they just swap who is custodial. The hearing got continued for a month “to give me time to open a case” allegedly at which time they would file to make the 700/month amount enforceable. I am skeptical.

Meanwhile, my ex didn’t even serve me with her income and expense declaration, and because she now has an extra month, she is just going batshit subpoenaing (incorrectly) all of my clients to try and prove that I (self employed) make thousands more than she does, so she won’t have to pay. I don’t, after actual business expenses, but I am sure she will take those checks to court and claim I am actually rich.

What are the odds I am actually going to see any of this money? What should I be doing in this extra month to prepare?
