You might want to talk to a small business lawyer or even just doing searches for free legal advice info on the net for your area. I've used both for another situation and found that about 95% of what I needed to know could be found on the net but a lawyer is very valuable to have as a backup for whatever decisions you make to cover your arse. As Squirtdad mentioned anybody can sue and just dealing with a potential suit can get very expensive even if you have no fault in the complaint.
