We sold our house and we have misplaced the manual for a few items: garage door opener, security system. All I think you can get online, but I’m not sure. Buyers are threatening to take this further (what do they mean?). I don’t remember ever thinking that the manuals were a necessary part of the house sale. We will try to locate them out of good will, but is there really an obligation on our part to leave manuals for every appliance and such?
