About Powr of Attorney
Greetings,
My wife died out of cancer; brain cancer. At the last month of her life, her sister came to visit and encourage her to go to court with her and give her power of attorney. With this letter, she not only cashed both of her bank checking accounts, but also charge her credit card. Now I have been referred as her husband to collection agency for about 11,000.00 US dollar that she charged to my wife’s credit card.Part of it after her death. Total amount she cashed out of checking accounts was about $12,000.00 She also transfered part of ownership of a house, $50,000.00 worth of stocks, and some jeweleries to herself. Is this correct. She took her to court when I was at work and without my consent. I doubt she knew what she was doing. Out of our many years of marriage, we never had a fight, never had any legal authority question us, and never needed a counseler. Is this how legal system of this country treat husband of a woman. If not, what right do I have to procted myself and have her sister pay the bill. It is now over 10 months that the collection agency calls me. The more I tell the story to the credit card company and the collection agency, the less they listen to me.What am I supposed to do? Thank you.

Changes to Revocable Living Trust
After 5 years of 5 siblings being the beneficeries of their fathers Trust the 1 sibling who was not only the trustee but also had power of attorney took the father to the lawyer 5 months before his death knowing he was terminally ill and legally blind had him sign a 1 page amendment stating she was to be the sole beneficery and dropping the other 4 siblings.. The lawyer just simply notorized the father’s signature. Should there have been other witnesses to this and also should the other beneficeries have been notified of these drastic changes?
