Circuit courts are a type of trial court found in many states in the United States. They handle a variety of cases, including civil, criminal, and family law matters. Each circuit court typically serves a specific geographic area, known as a judicial circuit, and is responsible for hearing cases that arise within that region. In addition to trial functions, circuit courts often have appellate jurisdiction, meaning they can review decisions made by lower courts. This allows them to ensure that legal procedures were followed correctly and that justice is served. Circuit courts play a crucial role in the overall judicial system, providing access to legal remedies for individuals and communities.
