We have a couple of guns that my wife calls "her" guns.Wife and I don't have separate accounts, but we've never had any problems with what to do with the money. Also, starting around 2008, she has been the one most interested in purchasing firearms. Sadly, after I suggested buying a "tactical" shotgun, we bought it, but she lays claim to it.
I'm like, that's fine sweetheart, they're YOUR guns. Now, I'm just going to go to the range and shoot them to be sure they're sighted in right. LOL
