My sister-in-law printed an online revocation of POA assigning herself and my brother as my mother's agents in California. She had a mobile notary sign after mother's signature. I had my mother in Assisted Living as her doctor told me she needed 24/7 care. After revoking my having POA, they moved her in to Independent living. This sister-in-law and my brother have "borrowed" thousands of dollars from my mother in the past several years. They never paid her back and also convinced her to get them credit cards which they also did not repay. Sister-in-Law told me that she is the one who had my brother take several thousand dollars from my mother's safe while mom was napping. This was just a few years ago and brother was caught in the act and had to return the money. Mother does not remember, but I remember her calling me to complain about them and I agreed to protect what little money they left her by remaining as her bank Trustee. This pair of bad actors assumed the money would automatically go to them when they assigned themselves to have POA. They are now avoiding Neurology appointments that Mom's last doctor referred for further testing of Dementia. They have simply changed doctors. In the meantime, because I simply would like to know the name of her new doctor and other medical contact information, I have asked my
sister-in-law to please provide. She will not provide me with this information. I had contacted APS prior because I had several concerns about Mom needing more care they said to depend on Mandatory reporters. Well, after a recent hospital visit, she is now getting more care which helps put me at ease with mandatory reporters around her. I realize that there is not much I can do as no longer having POA, but, as a daughter, don't I have the right to know the names and contacts for my mother's care?
If you suspect/have proof of fraud you need to get an APS involved at once. You need to have your proof with you. Accusations out of the blue are not enough. They will open a case.
You also can go for guardianship, carrying with you proof that POA was changed when your Mom was incompetent and that you were her POA (carry the proof of your meticulous records with you). You can tell the judge that these two are enriching yourself on your Mother's money if you have proof of this.
If you have no proof you just fell into the he-said-she-said realm of things. When a judge, who is not Solomon, cannot make a decision with squabbling siblings they will often remove the elder from the care of ALL SIBLINGS and will have a state appointed paid fiduciary managing all care, placement, sales, assets and etc.
I honestly think that you need the advice of an attorney, and sooner rather than later. Your Mom's trust PAYS for that and it is money well spent. Good luck to you, Missmydad.
