Help!

My ex and I seperated 2 years ago this august,I moved back to my home town in Indiana to establish my residence and after 6 months I filed for divorce,my husband works for a large global company that furnished his lawyer at no charge to him,after 2 years of legal hassle I gave in,went back to northcarolina and signed the seperation/divorce papers. I really had no choice,I could not afford to fight him any longer. I gave him everything he asked for,at that point I was exhausted,financially and mentally,he agreed to pay me my share of the equity in our home,in the legal papers it states that I was to be paid by April 10,2003,I have yet to see the monies and he is avoiding me,what can I do,I can not afford a lawyer,please help.
