N.Y. Real Property Law § 201: When deemed to have elected

§ 201. When deemed to have elected. Where a woman is entitled to an

election, as prescribed in either of the last two sections, she is

deemed to have elected to take the jointure, devise or pecuniary

provision, unless within six months after the death of her husband she

enters upon the lands assigned to her for her dower, or commences an

action for her dower. But, during such period of six months after the

death of her said husband, her time to make such election may be

enlarged by the order of any court competent to pass on the accounts of

executors, administrators or testamentary trustees, or to admeasure

dower, on an affidavit showing the pendency of a proceeding to contest

the probate of the will containing such jointure, devise or pecuniary

provision, or of an action to construe or set aside such will, or that

the amount of claims against the estate of the testator can not be

ascertained within the period so limited, or other reasonable cause, and

on notice given to such persons, and in such manner, as such court may

direct. Such order shall be indexed and recorded in the same manner as a

notice of pendency of action in the office of the clerk of each county

wherein the real property or a portion thereof affected thereby is

situated.
