Justice of the peace courts are local courts in Texas that handle minor civil and criminal cases, focusing primarily on low-stakes disputes and misdemeanors. These courts are often presided over by justices of the peace, who are elected officials responsible for maintaining order and resolving small claims, landlord-tenant disputes, and issuing search and arrest warrants. Their role is crucial in the local judiciary system as they help to alleviate the burden on higher courts by addressing simpler legal matters.
