About 20 years ago Mom & Dad signed the house deed over to their seven (7) children, with life use for them.
As Dad's POA and pending Executrix, I have been working with him to address many unresolved issues & questions about what another sibling did with his assets in her name and mine while holding his POA until late 2006.
She has been a license CPA for almost 30 years, by the way.
In addition to commingling his assets with "hers" (bought on margin using his assets as collateral for most - misappropriation, if I understand the definition correctly), sh managed to get me to approve transactions (for March 2000-November 2000) in my account through the broker while I lived in the midwest 10-15 years ago. This was done under the guise of following Dad's instructions while she was his POA at the time. In November 2000 the broker asked me to give her a limited POA because of the number of transactions she had been calling about. This would take him out of the loop. Unfortunately, it also allow her to remove thousands of dollars in checks which she forged to cash.
Fast forward to my return home over 3 years ago to care for my Mother and Father after years of traveling every other weekend from out of state to help and to do respite care. Thoughts of those unreported (to me) transactions, with my father receiving the brokerage reports all along - but not understanding them in full - prompted me to try to assemble all available records and reconcile his assets.
The battle was on when I started asking questions 3.5 years ago. She convinced four other siblings to side with her. The 7th is like Switzerland & wants to remain on the side, but understands many of the violations that the CPA sibling committed.
Hostility built and remains, leaving the family quite split and Dad heartbroken from learning his CPA daughter is so ruthless in accusing him of lying that his assets (moved into her name by her or him is TBD) were truly his.
Dad's current attorney is working with us to prove CPA sibling held Dad's assets in a constructive trust as recognized in NYS.
What options exist to protect me and my domecile from further intrusion or assault until I can get Dad's estate settled, house cleared out, and ready for market?
I'm sorry for the dissertation - abbreviated form. ;-)
