Revoking Pwr of Attrny originating in Guam, in California
A disabled man lived with daughter on Guam. Man authorizes General Power of Attorney to her while both lived on Guam. Both moved to Texas. Father-daugher relationship has severely deteriorated.

Man is now in California with sibling while daughter remains in Texas. Man wants to revoke the General Power of Attorney. Can it be done in California? He thinks he has to travel back to Guam to do it. Any insight appreciated. Thank you.

Seller / Buyer Same Person
Several years ago my late husband formed a real estate development corp. with my late parents. He had POA on all land parcels sold thru this corp. One of those parcels was purchased by us. My late husband signed for my parents as seller ( with POA ) AND he signed as buyer ( warranty deed ). Since then this piece of property has been subdivided. I recently tried to sell one of the lots and the Title company informed me that the warranty deed with my late husband signing as both seller and buyer is a problem. They told me that my 2 brothers and sister need to sign a quit claim deed in order to clear this title issue or, if this isn’t possible, pursue a quiet title action. If this case goes to court how big of a problem is the handling of this warranty deed likely to be ?
