My sister has recently had me removed as my mom's POA and joint checking. She regularly charges mom big $$$$ for her visits (long distance) and always leaves with some of mom's valuables, yet pitches a fit if mom gives me so much as a tea cup. I've avoided taking $$$ or valuables offered by my mom to avoid these scenes. Anyway, I'm totally fed up with being the dutiful daughter while my sis, who visits only when mom's not sick, gets the money, stuff and makes me out to be a villain.
The checking account went to ZERO.
You have to have documented proof and stay very clam at the hearings to show the Judge you are the opposite of the sibling. There is one in every family I have been told.
My mom is much better off with me in charge and my sister has not come back up as she now knows she is "CUT OFF" legally, from ever getting another penny.
I still do not like Probate. Once you go that route, they literally continue to suck the conserved person dry, through hearings and annual accounting's that are required.
Now we need a trustee to move money from WELLS FARGO to her credit union so I can pay bills. Probate will not let me do this since the conservatorship was contested....BY, my sister. I find this stupid since she acted like she was auditioning for a JERRY SPRINGER show at every hearing.
Now that will be a new bill, paying an attorney to be her trustee.
Nobody said this would be easy, and thankless.
Good luck and knowing you are not alone, should make you feel better. You cannot change your sister, but you can change how you react to her.
And I just finished describing your sister as the epitome of what caregiving should be all about: respect and unconditional love!!! No wonder you referred to her as your "sibling" instead of giving a name. I feel ... ... ... used.
Well, at least you know her love comes with a price tag. "Thou shalt not steal," but I hope she can sleep a bit at night. ... Bet she'll try to be your best friend after Mom and all that money is gone.
