The offenders husband, my brother, has Power of Attorney. His wife has my mothers bank account(s) access to my dismay because I know that she has been terminated from two jobs in her life over money disappearance. Her husband welcomes her meddling. My mother who is fading memory-wise very quickly.accepts her meddling. What can I do to protect me and 5 more siblings?.
If you have evidence, not rumor and suspicion, evidence of misuse of your moms funds call the police, prosecutor or APS.
If this is about wills and inheritance see an attorney. If your mom granted poa to your brother while mentally competent there's not much you can do unless there is indeed criminal activity.
I guess you can call me a meddler also. I have POA for my mom and manage her fiancés. When we realized mom had dementia - I took it upon myself to dig into her finances. She had fallen victim to multiple scam artists, was ripped off by buying a security system she never figured out how to use, was paying for an insurance policy that didn't even cover her any more due to her age, wrote checks to multiple charities, etc. etc. If you siblings are concerned that mom's funds are being mismanaged - then maybe you need a family meeting and have everything transparent. I was appalled when I saw how many bad choices my mother made her money.
I like you sister in law - also look after my mother-in-laws accounts. I do not, do anything wrong - I am just making sure everything is ok. My mother-in-law has dementia and cannot manage her affairs. We pay her bills, make sure her taxes are done etc.
Sounds like you need a family meeting and ask for transparency. I would do that before I pass judgment.
