My Dad is 88, and has multiple symptoms of dementia. He refuses or doesn't want to accept his condition. He is an attorney and will not give up his practice despite the fact hat he is funding the business with money from the family trust for several years. (He still thinks he is making money, so sad) He is the trustee of a family trust set up years ago. He is spending exorbitant amounts of money yearly. (well over 100k) How do i have him removed as trustee?
