Let's say someones uncle passes away and leaves behind.. say a S&W revolver that's pretty old, say bought in the '70's. He didn't sign a will, neither does he have any paperwork for the gun. Say this gun is at someones house, say his sisters house (In CA). What happens to the gun? BTW- No my uncle hasn't passed on... yet, he is however in very bad health. Don't mean to sound inpersonal, just a bit worried. BTW again: I'm only 15, so it wouldn't be my gun, although he would be "giveing it to me." Thanks, Mike.  

Legally go check the CA AG Firearms pages.  IIRC, In cases like that all you need to do is to have your parents complete an Operation of Law form  indicating it was given to them by your Uncle as a bequest to you.  This form is an after the fact form explaining how you (they) got it.  Costs $14 or did.  Don't believe there is a waiting period here or any additional costs.  The recipient has to be a legal recipient and the transfer can be a gift in the family or legal bequeathal, or similar transfer.  I think it has to be immediate family.

BTW a gun first bought in the 70's ain't old.  Or at least they weren't when I got some then.

Gun? What gun?
