Uncle Changed His Entire Will 4 Days Before Passing While On Heavy Meds.

My uncle passed away last Tuesday from complications related to late-stage cancer. He was 72 and we were very close, I was basically his primary caregiver for the last six months of his life since he never married and had no kids of his own. For years , he told me and my brother that his house and savings would be split between us. He even showed us a copy of his will from 2018 that confirmed this.

However , when we started the process of settling his estate , a guy showed up claiming to be my uncles "best friend" from some online hobby group. He produced a new will that was supposedly signed just 4 days before my uncle died. In this new version , everything goes to this guy. My uncle was in the hospital at the time , on very heavy doses of morphine and other pain killers. He was frequently confused and didnt even recognize me a couple of times during those final days.

The "friend" says it was my uncles dying wish because we "didnt care for him enough" which is a total lie. I have records of every doctor visit and grocery run I did for him. The new will looks official enough but the signature is very shaky , way worse than his usual writing. I suspect this guy pressured him or took advantage of his mental state while he was high on meds.

What can I actually do here to contest this? Is the fact that he was on heavy narcotics enough to prove he lacked capacity to sign a legal document? I dont have ten thousand dollars to throw at a lawyer right now but I cant let this stranger just take my uncles life savings. Do I need to report this as fraud to the police or is this strictly a probate court thing. Any advice on how to start a will contest in NY would be great because I am completely lost and overwhelmed.
