I have a Irrevocable A/B Trust, my husband passed away and I am the Trustee. I am ill and dying, back in 1994 when my husband and I set up this Trust we choose 2 of our children to share as co-trustees when the last one of us is to pass. One of my children that is named as a co-trustee has become a alcoholic and I feel that his drinking will become a nightmare for my other child. Is there a way I can change this and have him removed as co-trustee? I am even willing to have him enter a treatment program and have his problem monitored by professionals until the time he can be responsibile to help my other child with this duty.
