Can I give a firearm to my adult child? Can he/she give it back to me later?
Yes, as long as the adult child receiving the firearm is not in a prohibited category PDF logo [PDF 10 kb / 1 pg] and the firearm is a legal firearm to possess, the transfer of a firearm between a parent and child or a grandparent and grandchild is exempt from the dealer transfer requirement. However, if the firearm is a handgun, you must submit a Report of Operation of Law or Intra-Familial Handgun Transaction PDF logo [PDF 481 kb / 2 pg] and $19 fee to the DOJ within 30 days. Assault weapons may not be transferred in this fashion. See Penal Code section 12285, subdivision (b).
