If you are covered by your husband's health insurance plan, you are entitled to COBRA coverage upon divorce. It can be costly, but it is better than no coverage. You can read about
your rights here:http://www.dol.gov/ebsa/faqs/faq_consumer_cobra.HTML
Also, your divorce attorney should be able to explain your rights regarding this. Also, if your husband really wants a divorce, what about
having him help pay for the cost of the COBRA coverage?
