I have never read this in the law but I do have an anecdotal story.
A guy I know lost his Erie county pp due to an accident he caused while on his prescription medicine while carrying a pistol.
This is the way I was told so I dont want an argument please .....this is the very probable story.
Anyways, the EC sheriff took possession of his pistols but said his long guns were fine to keep.
Their explanation was that he didnt become disqualified from owning a gun.....but the issuing agent revoked his pistol permit due to driving and crashing on pain meds, anxiety meds and anti depressants..... This was about 4 years ago.
33 yr old son lost his CCW? How so?... What automation mechanism caused this? Who involuntarily had him admitted and based on what criteria? It's completely subjective, and could be arbitrary and capricious even if issued by a judge. Of course, in the name of "Safety" Law and Constitution is completely disregarded and is why in these situations legal counsel is highly suggested!
As for co-owners of firearms with the other party having forfeiture if their property due to the other having legal issues... Ummmm, just no, not possible! And any attempt to do anything remotely similar to such action would require immediate and escalated legal action with prejudice! They don't even take cars from DUI's because someone else in the household uses the vehicle for work, etc. As noted, only sticky situation comes if the person under order resides in the same household and then is considered to have access, even if they're secured.
OP hasn't been back... So, we're left to wonder what's happening
OP, I'm sorry that you have to go through this because of your son's actions. I hope he gets whatever help he needs thru this time of crisis for him.
I also hope you get whatever guns you need to hang onto until your son comes to his senses.
