2006 Massachusetts Code - Section 7. Barring of dower by jointure before marriage.

Section 7. A person may be barred of dower in all the land of such person’s spouse by a jointure settled with assent before the marriage, if such jointure consists of a freehold estate in land for life at least and is to take effect in possession or profits immediately upon the death of such spouse. Assent to such jointure shall be expressed, if such is of full age, by becoming a party to the conveyance by which it is settled, or, if a minor, by joining with the parent or guardian of such person in such conveyance.
