In what year was the common law system officially adopted in Texas?

The common law system was officially adopted in Texas in 1840. This adoption occurred during a significant period in Texas history when the region was transitioning from a Mexican territory to an independent republic and then later to statehood. The legislative foundation for this adoption was established by the Republic of Texas, which selected to use the common law principles that were already established in the United States. Thus, 1840 marks a pivotal year, as it set the groundwork for the legal system that would govern Texas moving forward, integrating common law along with local statutes and regulations.
