My co worker bought my Sig from me. We haven't done the transaction yet. I plan on writing up a bill of sale for the pistol. Here are the two questions I have... Since it's a private party sale what info should I write on the bill of sale beside names, addresses, DL# of the people involved? Does he need a Permit to Purchase from me? Or because it's a private party there won't be any paperwork involved he doesn't need one? I just wanna make sure that if something were to happen down the road (he sells it, get stolen, or god forbid it's used in a crime) I don't want it to come back and bite me. I know my Dad's Ruger is still in the name of his old co worker. And when that gun was stolen he was kinda worried about what would of happened if the guns were used in a crime. Would he be in trouble? I did google the subject but didn't really see any good info.
