New York Consolidated Laws, Real Property Law - RPP § 197. When dower barred by jointure

Where an estate in real property is conveyed to a person and his intended wife, or to the intended wife alone, or to a person in trust for them or for the intended wife alone, for the purpose of creating a jointure for her, and with her assent, the jointure bars her right or claim of dower in all the lands of the husband.  The assent of the wife to such a jointure is evidenced, if she be of full age, by her becoming a party to the conveyance by which it is settled;  if she be a minor, by her joining with her father or guardian in that conveyance.
