I am dealing with this person because he was Dads businesses partner. He took care of property and renting stuff when Dad died. Company was sued and settlement was reached a year ago. The law firm has been trying to get final payment for services. He would not pay. Said lawyer did everything wrong. They owe mom money. Law firm finally contacted me. I paid bill. So I get call with yelling and very angry rant. Why did you pay? Mom could get a lot of money back. They messed up the case, etc. I Talked to lawyer. He said Sam couldn't understand that he still owed. Even when it was explained over and over. Lawyer said Sam was happy at settlement and hugged female lawyer. Said his memory seems to have gone down hill in the last year. But other than that he seems rational. How do I talk to a person that I can't reason with. That can't remember what really happened. When he is angry and saying you don't want me to have to go to mom for money for lawyer to sue old lawyer. Mom in rehab nursing home. I can't dodge his phone calls forever.
