My recollection (don't have the laws right in front of me) is yes. They're supposed to be surrendered to the police, but can then be transferred to a dealer of the owner's choice or to any other properly licensed person, which would include the licensed spouse. Some PD's might insist on taking the firearms, getting a written statement from the owner requesting their transfer, checking the spouse's license, and generally making as big, awkward and expensive production as possible; others might simply allow the spouse to take immediate possession. It all depends on the department and the situation.
