Starting in the early 1950s, Israeli women's organizations persistently promoted legislation that aimed to ensure wives' just share in marital property, until in 1973 the Knesset enacted the Spouses (Property Relations) Law. This remarkable struggle was then forgotten. The long history of this law as told here, along with parallel Israeli legislative and judicial developments related to property relations between spouses, reveals the political activities of women's organizations during the decades in which it is generally believed that they neglected their political-feminist agenda. It also discloses the substantial gap between the organizations' vision of a community property regime throughout marriage and the regime of property separation enacted into law. This case study sheds light on how social organizations attempt to promote legal reforms and on the consequences of their compromises.
