My ex has had to keep health insurance on me until time of divorice. Which he has done for 10 years.I am now unemployed and due to health problems brought on by being diabetic I need this health insurance more then ever. He now says he wants to file for divorice and will, leaving me totally uninsured as well as unemployed, if I dont sign something stating I will not ask for any settlement .In return he will not file and keep the health insurance on me for another year. Is this legal? What other options do I have?
