Before 1848, a few laws were passed in some states in the U.S. giving women some limited property rights, but the 1848 law was more comprehensive. It was amended to include even more rights in 1860; later, married women’s rights to control property were extended still more.
The first section gave a married woman control over real property (real estate, for instance) she brought into the marriage, including the right to rents and other profits from that property. The husband had, before this act, the ability to dispose of the property or use it or its income to pay for his debts. Under the new law, he was not able to do that, and she would continue her rights as if she had not married.(https://www.thoughtco.com/1848-married-women-win-property-rights-3529577).
