My Father’s Ability to Usurp a Potential Conservatorship
My parents live in Mississippi where one of my brothers also lives. My father is afraid my brother in Mississippi may be attempting to obtain conservatorship over him and my mother. My mother has Altzheimers and my brother has said that a doctor in Mississippi has diagnosed my father with senility. I’ve not talked to this doctor and no one else in the family was aware of the testing performed. Plus my father has NOT been informed of this diagnosis. My brother has mentioned, he fears my father cannot take care of my mother or himself. The rest of the family believes my father still has the capacity to handle his affairs and take care of my mother. He does manage his finances and does ensure my mother takes the necessary medications needed for her illness. My father wants to usurp any potential plans my brother in Mississippi has of pursuing conservatorship by giving power of attorney to myself and/or another one of my brothers. Can we stop the conservatorship, if my brother has already started that course, since he is in Mississippi, where my parents currently live and we are in LA? Will a durable Power of Attorney supersede? Should my father establish an estate plan and how much money does this normally cost?

Elder law My mom has dementia.

Elder law
My mom has dementia. She lives alone and is progressively getting worse–she doesn’t eat, take her medications regularly etc. She refuses to let anyone come into her home to provide assistance. She lived with my sister and brother for a while last year but became delusional at night and basically left each place and finally went back to her own home. She has dificulty walking due to arthritis, is on lots of meds. She fell this past year and broke her leg. After her rehab was over we tried to encourage her to go to an assisted living facility -and while we were looking- she stayed in the SNF for 1 extra week, then checked herself out. She also cannot remember to pay her bills etc. We are very worried about her safety and her s ituation. My sister has a durable power of attorney for my mom. We are looking at some nice assisted living facilities and trying to nicely get her to go..but if she tries to leave… and there are safety issues living by herself, what can we do to protect her? Does she have to be declared incompetent? We don’t know what to do. We want to take care of her and make sure she is safe..but she doesn’t want to leave her home or let anyone in. What can we do??

Does state take everything if catastrophic illness occurs?

Does state take everything if catastrophic illness occurs?
My mother is seriously concerned about losing all her assets in the event she suffers a catastrophic event ,i.e., stroke, alzheimers, etc.. She believes that if this were to occur, the state would automatically get everything (home, invest,ents, car, etc)she has ever owned. Is this true? If so, what can be done to prevent it?
After reading many posts here, it seems a durable power of attorney might be one way of stopping this – she also has a living will (she doesn’t want to be resuscitated in event of heart attack) and a will that – will the POA make her sleep better and allay her fears?
