I am DPOA over both parents and they were both deemed incapacitated. Doctor said to put them in assisted living. Now my brother is ( 55yrs. old and who has been freeloading and living in my parents house) furious as he is now cut off of the money and credit cards of my parents. He is now going to try to get gaurdianship. He was forclosed on 3yrs ago . My parents feel sorry for him because he constantly upsets them with his tales of woe. Now they want to get a lawyer to revoke my DPOA. Can this be done?
