Husband and wife agreed with each other to make mutual wills which would leave one-third of the estate of the survivor in equal portions to seven relatives, four of whom were the mother and three sisters of the husband and the remaining three, a niece and two sisters of the wife. After the husband's death the wife made another will, revoking the former one and providing for a different distribution of her property. After her death the mother and three sisters of the deceased husband filed a bill for the specific performance of the contract to make mutual wills. Held, that the relief should be granted. Smith v. Thompson, 250 Mich. 302, 230 N.W. 156.
