Is there anything I can do at this point if I walk out with nothing after 20 plus years of marriage, and he never gave me a penny?

I was divorced about three years ago. I had no attorney and made $9.00 an hour. My husband at the time made over $100,000 a year and hired an attorney. Right before our court date, he said not to worry and he’ll make sure that I get money every month so I signed off on maintenance and his pensions.
