My cousin lives in Texas. I live in Louisiana. My Aunt will be in town this weekend. (his mother) My cousin wants to purchase a firearm I have and just let his mom take the gun from me this weekend and he will send me a check for it. (No biggie on my end, I don't mind doing that, he is trustworthly blah blah blah) What legalities will I run into doing this? Can I just do a regular bill of sale with my Aunt and turn over the gun or is there a slew of state to state purchase laws that I will have to deal with? Thanks for the info, I just wasn't sure about state to state stuff.
