They are probably trying to serve you with a subpoena to appear for a deposition. First thing you should do is call your old company and see what is going on. They should be able to put you in touch with the attorney handling the case for them. The outcome of that discussion will decide whether you need your own lawyer or if the company's lawyer can handle it. Also, call your insurance company, if you still have a commercial insurance policy that covers you. They might provide you with an attorney.

You can't avoid service indefinitely and it will bother you as you wait for it to happen. You might as well get it out of the way.
