My parents have been great to me and my two siblings our whole lives. The problem is they've been stuck raising my niece since her adolescence because my sister has been an irresponsible drug addict most of her life. My sister is sober now but the damage has been done.
Right now my niece is 21 years old and spoiled rotten by my mom. She's been verbally and occasionally physically abusing them since she started living with them full time at 13. The final straw came when she had her freeloading, drug addict, 23 year old boyfriend gradually move in who in turn had his freeloading drug addict buddy start to move in. They've been using, scoring and dealing drugs right out of her room. My dad would usually put a stop to these activities but now he's worn out and has capitulated to my mother's blind devotion to her granddaughter.
Now my mother AND father are vehemently defending the two brats as they drain their bank account for drug money under the pretense of concert tickets or some other type of entertainment. Right now they both get hysterical whenever we try to intervene on their behalf. They are 79 and 80 years old and we are very worried about the stress my niece and her boyfriend are putting on them.
I need to know how my brother and I can get some power of attorney over my parents when they will be stubbornly reluctant.
