It may be wise to have your specific factual situation analyzed by an attorney in your jurisdiction. And you should have this done IMMEDIATELY so that you don't lose important rights. Many lawyers offer a free or low-cost initial consultation just for the purpose of determining whether they can help you. Don't be afraid to contact them. Our Lead Counsel Panels at http://www.lawinfo.com/law/ are a great way to find a lawyer in your area on the internet. Best of luck!
