Not a lawyer, but I ran a similar gauntlet when my Dad died (fortunately, there was a Trust…not a “Gun Trust” but a revocable trust containing a will)).
Is there a Trust or just a will? If only a will and the value of the estate reaches a certain level, there is an annoyingly long and expensive probate process ahead of you.
With a Trust, the Executor can act without probate and doesn’t need Letters Testamentory from the court.
Unless a will specifically designates assignment of the firearms to specific individuals, the firearms are usually assets of the estate. That makes their value available to all heirs. The heirs who don’t want to accept the firearms may need to sign a disclaimer of inheritance for the firearms, essentially forsaking any financial considerations for passing on the guns. Otherwise, they may be able to claim a financial offset of the guns’ values against the rest of the estate. The guns then go to the remaining heir (your wife).
As an inheritance, she can execute an
Operation of Law for
all firearms for a fee of $19, total. She needs a Firearms Safety Certificate to do this. The guns are then in your house. At a future date, your wife may gift them to you or you and she may agree to transmute ownership solely to yourself.
Your BIG problem right now is if this is a will which needs to go to probate.
