You really need to kick this one around with an attorney- I never passed the bar (always stopped off for a beer)
In GENERAL terms- a felon may not POSSESS a firearm. That means to hold one, or have the ability to hold one. If they are in the house and not physically secured, or under direct physical control of another person- you would be considered to constructively possess that gun.
That's 5 years, no probation.
I only offer that since I have a stepbrother who made some bad choices as a young man- when he visits our home, my stuff that is not on my belt needs to go under lock.
You CAN own a gun, and you CAN sell a gun- but you cannot possess a gun. You REALLY do not want to TOUCH a gun- your best bet may be to find a dealer that will sell them on consignment- have the dealer recieve them directly from the estate so that you are never in the chain of custody- and do talk with a lawyer.
What we have here is... failure- to communicate.
