My wife & I bought my 92 y/o Dad's house with the stipulation he could live with us as long as he wants, and that he was not to use his power tools in the house as my wife has problems breathing when saw dust in air. About 4 yrs ago, he lost balance & fell into the table saw and almost cut his fingers off. We came home 1 day after running errands & he was using the saw & planer, putting dust in air. Told him to stop, he refused. Wife said she would cut the cord. He threatened to kill her. He always carries a 357 revolver everywhere. Luckily, he had left it on the saw table when the confrontation began & I took it & hid it. I removed all guns from the house. For 2 weeks, he keeps asking for it back. He apologized & said he'd never hurt my wife, but I don't trust him.
Then make a choice between placating your father and having a wife.
I would see a lawyer asap about the stipulations in the sale document. Is this a "life estate"? Most life estates don't come with the condition that the person may remain in the home when they are a danger to themselves and others (which your dad is).
I would encourage you to remove all weapons, ammunition, power tools and sharp objects until you can get dad seen by a neurologist, geriatric psychiatrist or behavioral health team.
If he has an episode of rage and threatens, call 911, have him transported to the ER and tell them that he is no longer able to be safe at home. And that you and wife are in fear for your safety.
Eta, is dad ex-law enforcement, military or organized crime?
The Law and Order Elliot Stabler is all three of these things, or at least two. This franchise is now 22 years old. In less time than that, we could be dealing with the dilemma of how Stablers kids remove his gun and ameliorate his attitude lol
Does your Dad suffer from dementia? Does he have a history of violence?
Is there any missing information in this story that you can give me so that I can understand why you bought your Father's home, assuring him he could live in it for life (which was unrealistic assurance on the face of it)?
Is there some information you can give me that might help me understand your questioning whether to return guns to an elder who has already threatened the head of household with death by same?
You might want to discuss this with your local police, right now.
