Ok, say I'm selling a handgun, I've verified the purchaser has either a concealed permit or a Nebraska Handgun purchase permit......what do I do with this information?
Neb. Rev. Stat. § 69-2403 prohibits the transfer of a handgun to anyone who doesn't have a purchase permit, doesn't have a CHP, isn't a LEO, isn't a federal firearms licensee, isn't a close family member, etc. There is also a specific exception for "antique handguns," a term that is defined in
Neb. Rev. Stat. § 69-2402 as: "any handgun or pistol, including those with a matchlock, flintlock, percussion cap, or similar type of ignition system, manufactured in or before 1898 and any replica of such a handgun or pistol if such replica (a) is not designed or redesigned for using rimfire or conventional centerfire fixed ammunition or (b) uses rimfire or conventional centerfire fixed ammunition which is no longer manufactured in the United States and which is not readily available in the ordinary channels of commercial trade"
To answer your question, I would say that if you are a private seller of a handgun, once you have seen the prospective buyer's purchase permit or CHP, you can permanently transfer a handgun to them. In a criminal case, you don't have a duty to prove to anyone that you complied with the law because the burden is on the state to prove beyond a reasonable doubt that you committed the crime charged. The prosecutor has to prove that the elements of the crime have been met. With that said, it may be prudent to keep a copy of the permit that you relied on, keep a copy of the bill of sale, etc., so that if you should ever end up accused of something you have readily available evidence that tends to support the inference that you complied with the law. I am not aware of any state or federal statutory duty on the part of a private (non-FFL) seller to maintain any of these records, though.
