If you do not have children with your new husband, the court does not even ask for your income. I had the same issue.
My husband got laid off and was on unemployment. Instead of giving us a break, his ex made us go to court to have the
child support reduced. Because in her mind, I should have had to pay the remainder of the child support so she didn't lose anything.
When we went to court, she TOLD the judge that I should have to pay the rest, talk about blood sucking. The judge told her my income was off limits and she should never expect that I would pay one cent to her children. He actually got upset with her arogance. I have two children of my own that I have never received child support for, but she wanted my money as well!
So the court system (Anoka County, surprisingly) worked in my favor that day. If we had a child together, the courts would request to know my income, but I do not know if that factors into their decision.
I wish there were some options in this state so the non custodial parent could do something about custodial parents who are only in it for the money. The mother of my step children is not a good mom to them and they prefer it at our house, but she would fight to keep her check, which finacially, she doesn't even need. *sigh* getting off topic
