My boyfriend has been separated from his wife for 4 years. They have worked with a mediator for almost a year but every time they get close to an agreement she makes unreasonable demands, such as that he keep her on his health insurance after the divorce. She has had the agreement for more than 3 months but won’t sign it or make a counter proposal. What options does he have to divorce her if she just won’t sign the agreement? He does not have much money for legal representation or a court battle.
