Legal Question in Family Law in California

Re: Abandoned Property

from the facts given, if you were gifted a piano from your grandparents, and your uncle has no valid legal claim to it, then the piano is your property period. if your uncle is threatening legal action without a basis citing any legal claim to this piano, this could be viewed as "harassment" in which you may have actionable counterclaims against him. further, even if your uncle does have some valid claim to this piano, which was not mentioned in your post, its highly unlikely that you would have a legal affirmative duty to deliver the piano to him, and you would have done the right thing by giving him a time limit notice to come pick it up before selling it, at least from the information you have submitted thus far. you may want to consider speaking directly with an attorney on this matter so all the facts are brought better to light.
