Greedy Uncle Is Ruining Lives, Desperately Need Any Help.

Hi. I’m desperate, so I made this account to post here. looking for location: Utah and California. Long story short, my grandma died in May 2024. Lived in Utah for the last large part of her life. She had been diagnosed with Alzheimer’s for maybe 8-10 years. I was the favorite grandchild, and was very close with her. She had 7 kids. Anyways, in the 90s to 2000s, my uncle (we’ll call him jay) co-owned a house with my grandma. He went behind her back, and took money out of the house. Not an expert on real estate, so I don’t know how. he took the money and bought himself a motorcycle, in case you’re wondering. Then he tried to evict my grandma. This erupted into a large family battle, where around $5,000 dollars was spent getting his name off the house. My grandma was ashamed and disowned him. To the point where she was told by her siblings at a wedding that occurred years later “please forgive him, I’d do anything to have my kids talk to me,“ and she responded “I will never forgive him.” She was soft spoken, so big mic drop. At that same wedding, Uncle jay went in for a hug with my (asshole) grandpa, and he stuck his hand out for a handshake. Anyways, fast forward to 2020. my grandma has had alzheimers for around 6 years by this point. Sorry, need to give context. my grandpa was a horse trainer all his life, and my grandma was an executive for general motors, which means she moved the family around a lot, meaning my grandpa had to restart his horse business everytime he moved. Anyways, in 2020 my grandpa got back in contact with uncle jay, and decides to move in with him on his private ranch in California. Could give so many crazy details, but holding back with the hope someone is reading that is considering giving help. My grandma, in my opinion, was abused during her stay at uncle jay’s ranch. She would be left alone doing nothing during the day while my grandpa and sometimes uncle jay (he had a separate house in L.A, but would frequently go back and forth) were outside doing yard work. She’d try to make herself useful, and wash dishes, but forget to put them in the dishwasher, then uncle jay would come in and yell at her. Towards the end of her life, my grandma didnt recognize uncle jay, but would frequently call “that man” an asshole. here’s the legal trouble part. before she died, probably a few months before her death, without anyone knowing, uncle jay and presumably my grandpa had my grandma sign documents that made a new will and A new trust fund, not only putting uncle jay back into the will (he was previously taken out) but made him the executor!!! my mom, my aunt, and my other uncle are obviously fighting back, but the battle rages on and their funds are starting to deplete. i desperately need advice to give them, and will more than happily answer questions.
