My dad is 88, on-set dementia/Alzheimer's and has a part-time caregiver in an independent living community. His 2nd wife has a long history of stealing money ($250K and 6 lawsuits) as has her family. As my dad's caregiver states, "she's a piece of work" and "he's being manipulated". We have suspected this for years but now it's confirmed. Wife refuses to give him the meds his doctor prescribes says she knows better (he's had 2 hospital stays because of it). Wife told my dad she needs more of his estate and is getting him to change his will to cut his family out. She has plenty of money (or did until she bought her daughter a house) and dad has already left her a substantial amount (more than she'll use in her lifetime).What recourse do we have to stop her from manipulating him into changing his will when he doesn't understand what's going on? She also keeps telling us that they don't have much money (Dad had lots of money 2 years ago). Caregiver said she's not giving him near enough food and he's lost some weight. She now takeshim to the dining room so he can get a substantial breakfast. Dad's wife HATES us and she's inserting her toxic drama into our family making it hard for us to visit him (she also monitors his phone). Dad says he's confused and doesn't know what's going on and she's manipulating him. HELP!
