My parents changed their wills over the summer. They have kept track of the money that they have spent on my brother over the years, and that amount will be deducted from his share of the inheritance. My parents also have your fear of what he would do with a large sum of money. For that reason, they set up my brother's portion of the inheritance in a trust of which I am the executor. They have made it clear that I am not to give him large sums of money, and wish for me to ensure that his basic needs are met. If necessary, I am to pay his bills directly so that he cannot have the money. My parents sought out the help of an attorney to do this. This is a huge responsibility for me, but I am willing to do it if it brings my parents some piece of mind. My husband agreed to do it if I was unable to do it for some reason. Of course when his inheritance runs out, he is on his own. My husband and I will NOT give him money that we have worked hard for. Good luck!
