Originally, women did not have property rights. Their husbands or fathers managed all their financial resources. This changed in April of 1848. The Married Woman's Property Act was passed in New York so that inherited land would belong to the daughter not to the son-in-law. Since this act was passed, Elizabeth Cady Stanton and Lucretia Mott decided it was a good time to hold a women's rights convention.
"The same year of the convention, the Married Woman's Property Bill, which had given rise to some discussion on woman's rights in New York, had passed the legislature. This encouraged action on the part of women, as the reflection naturally arose that, if the men who make the laws were ready for some onward step, surely the women themselves should express some interest in the legislation. Ernestine L. Rose, Paulina Wright (Davis), and I had spoken before committees of the legislature years before, demanding equal property rights for women. We had circulated petitions for the Married Woman's Property Bill for many years, and so also had the leaders of the Dutch aristocracy, who desired to see their life-long accumulations descend to their daughters and grandchildren rather than pass into the hands of dissipated, thriftless sons-in-law."
