Which type of court has magistrate functions in Texas?

In Texas, Justice of the Peace Courts have magistrate functions as part of their role in the judicial system. These courts are primarily responsible for handling minor criminal offenses, small civil disputes, and performing various judicial duties, such as conducting preliminary hearings and issuing search warrants. Additionally, Justices of the Peace can perform marriage ceremonies and serve as magistrates in certain criminal and civil cases, thereby facilitating a wide range of legal proceedings at a localized level.

District Courts and County Courts generally handle more serious criminal cases and a broader range of civil matters compared to Justice of the Peace Courts, but they do not specifically focus on the magistrate functions that are characteristic of Justices of the Peace. Family Courts, while specialized in family law matters, do not have the same jurisdiction or magistrate tasks as Justice of the Peace Courts. Therefore, among the choices given, Justice of the Peace Courts are distinctly recognized for their designated magistrate functions in Texas.
