My question is pertaining to a General Power of Attorney -
To make the question clear here is the situation -
1) A property is registered to 4 people. Out of the 4 owners, 2 owners have passed away.
2) One of the owners uncles claims that he was given an irrevocable GPA by the 4 owners a long time ago and is now executing it, 30 years later.
My question is, is this claim valid? I would really appreciate your experts insight on this.
