My mother passed away on May 5th 2019. She lived with me and I was her full-time caregiver for over a decade. In her will I am the executor, had power of attorney and was left all her assets. Now my older stepbrother who was not involved with her care, wants half of everything and is sending threatening text messages. There wasn't much left in the estate, and I can't afford an expensive attorney. She just wanted to make sure that I could take care of myself when she was gone, now he is trying to take the money she left me. My mother specifically appointed me executor of the will, because she knew what he would do to me if he was executor. He would sell the house, liquidate all the assets, pocket all the money and kick me out on the street. My mother even said: "He's my son and I love him, but he will try to take the gold out of your teeth."
I am disabled myself and my health issues are getting worse.
Any advice on how to protect myself from my unscrupulous stepbrother?
