In the case of Duff-Kareores v. Kareores, the Supreme Judicial Court of Massachusetts addressed the calculation of the length of marriage for alimony purposes. Ellen Duff-Kareores and Christopher Kareores were initially married in 1995, divorced in 2004, cohabitated, remarried in 2012, and divorced again in 2013. The court examined whether the period of cohabitation between their marriages should be included in calculating the length of the marriage for alimony duration. The court concluded that the period of cohabitation where the parties maintained an economic marital partnership should be included, but the time between the first divorce and the start of cohabitation should not. The case was remanded for further proceedings to reassess the alimony award based on the revised length of the marriage.
