Beware of Relatives

Relatives are first in line to screw you. I have seen more times where it is family that is dangerous than strangers. My own story is sad but the story of my 95 year old Auntie is sadder.
Auntie is a WWII vet, single and has worked all her life and saved her money. In 2008 the the niece that was to care for her died. At the time she was blind and could not walk. Her darling Sister and Brother-in-Law offered to help her. The brother of the niece, Auntie's Nephew seems to be a jerk. Niece was on Auntie's bank accounts as a safety feature, as all elderly people are advised to get another to help with these things just in incase. Nephew decided that everything in Auntie's accounts was half his sister's! He took it out and left Auntie high and dry. Sold the house out from under Auntie- Auntie built this house, paid for it and paid all the property taxes, paid off the mortgage for Niece since she was dying of cancer.
Everyone( sister, brother-in-law, nephew) decided that half of the money from Auntie's account now belonged to them.
I get a letter from the Sister's lawyer telling me that Sister and Brother-in-Law have graciously let Auntie live rent free in her own house( they bought the houses from Nephew (Dead Sisters house and the house that Auntie built and paid for on the same double size lot.) Plus they said they were paying all the expenses of Aunties since the Dead Sister's death. However I have all the canceled checks and all the bank balances and Auntie paid every cent of her expenses and all the property taxes and related expenses of her house. Yet they say they were gracious enough to let her live in her own house rent free.
I am not going to tell this to their lawyer. He is a lawyer after all, and his ethics are with his clients. Since his clients have no conscience and told Auntie she is living too long anyway why should I spend my money to fight them? May they rot in their own living hell. I have Auntie in my home where she is safe fed and cared for. No more days of isolation and worry about what is to become of her. No one should be victimized, especially by family. But They are the first in line to screw you.
