Every jointure, devise and pecuniary provision in lieu of dower is forfeited by the woman for whose benefit it is made in a case in which she would forfeit her dower; and on such forfeiture, an estate so conveyed for jointure, or devised, or a pecuniary provision so made, immediately vests in the person or legal representatives of the person in whom they would have vested on the determination of her interest therein, by her death.
