Article 6 - (189 - 207) DOWER AND CURTESY
197 - When dower barred by jointure.

§ 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.
