In several US states, including Pennsylvania, Oklahoma and New Jersey, some lawmakers are attempting change of divorce laws as they pertain to alimony. Massachusetts law provided for lifetime alimony, but in early 2009 a reform bill (HB 1785) backed by a group called "Mass Alimony Reform" gained 72 state representatives as co-sponsors (of a total of 200 Representatives and Senators). HB 1785 would have required a spouse receiving alimony to become self-sufficient after a reasonable time. It would have established alimony as a temporary payment instead of a permanent entitlement. This law would also have addressed the issue of cohabitation where the alimony recipient is living with, but not married to a new significant other. In January 2011, the bill was filed with the Massachusetts legislature and was passed unanimously by the legislature and signed into law on September 26, 2011. The law, which took effect on March 1, 2012, provides for different categories of alimony, and limits the duration of alimony.
