Legal Question in Real Estate Law in New York

I am not clear as to the facts of your case. If you are the owner of property, someone else cannot transfer your property in their Will, and/or through a Power of Attorney. If you require the assistance of an attorney, please feel free to call me at (212) 786-7539 for a free initial consultation. All the best.

I agree with John - your facts are unclear as to what you are asking. Like John, if you are merely an owner of land, on which someone has built a building (so you own a land lease) you cannot do anything with the building, but you can sell the land subject to the lease. You do not need a Will or a POA to sell or transfer your land. As I said, more facts are required to better understand your question and reply further.
