That's a great question. I don't mean any disrespect to the posters below, but this is a legal question that should be answered by an attorney, not a real estate agent.
There's no way I'm going to even try to answer here because its complicated and yes you face potential liability depending on your course of conduct. But that potential MAY be very low and MIGHT outweigh the benefit to be obtained by accepting that risk and acting accordingly.
I suggest you make an appointment with the King County Bar Association Neighborhood Legal Clinic (google it) which will get you 30 minutes for free with a licensed attorney. Alternatively, you can give me a call and if you're willing to pay me for my time -- its all I have to sell in order to make a living -- then I can explain your options. In any event, good luck!
