§ 1223. Alternative to escheat. If it appears from the records of the United States that the rightful owner of any property subject to escheat under this article has not made claim thereto for seven years and the attorney general does not deem it advisable to institute an escheat proceeding with respect thereto, or has instituted such a proceeding but has not obtained a judgment of escheat therein, such unclaimed property may be deemed abandoned property and shall be paid or delivered to the state comptroller for disposition in accordance with the provisions of this chapter and the provisions of section ninety-five of the state finance law.
