New York Consolidated Laws, Real Property Actions and Proceedings Law - RPA § 1755. Proceeds of sale deemed real property

A sale of real property, or of an interest in real property other than a possibility of reverter, of an infant or incompetent person, does not give to the infant or incompetent person any other or greater interest in the proceeds of the sale than he had in the property or interest sold. Those proceeds are deemed property of the same nature as the estate or interest sold until the infant arrives at full age or the incompetency is removed. The proceeds of the release of a possibility of reverter shall be deemed and treated as if they were proceeds of real property of which the infant was seized and possessed. If the incompetent person dies after the sale, having specifically devised the property sold, the provisions of section thirty-six of the decedent estate law  1 shall apply to the devise.
