I have P.O.A. & want to do things legally. I want to know when it is legally my job to take over the financial decisions, paying bills etc. ? I have P.O.A. of both parents.My dad has cancer and in hospital, not expected to have a good outcome and mom has mental problems and possible dementia(not diagnosed yet).She canceled her last psychiatrist appointment and won't take her medication. The psychiatrist office called me because they are very concerned about her. I have a sibling who can't help due to drug addiction. So it all falls on me to take care of them. They have been making VERY BAD financial decisions for quite some time now. I just learned the details of it a couple of weeks ago. Some dealing with my sister and insurance/ bank loan fraud. I have a real mess on my hands! If anyone has an answer, please let me know. Thank you.
