The district court has exclusive jurisdiction over felony cases, cases involving title to land, and election contest cases. It shares jurisdiction with the county courts, and in some case justice of the peace courts, for civil cases (its lowest limit for hearing a case is a mere $200 in controversy, while JP courts can hear cases up to $10,000). Family law jurisdiction varies depending on the existence of a county court-at-law; in some counties, the district courts share jurisdiction over divorces, child custody and support matters, adoptions and child welfare cases with county courts at law. Probate jurisdiction varies, depending on the existence of a statutory probate court in the county. In some larger counties, such as Harris County, the district courts are specialized, with designated sets of courts hearing criminal cases, juvenile cases, family matters, and non-family civil cases in four different court houses surrounding the square with the underground jury assembly facility, which suffered severe flood damage in Hurricane Harvey. In the smaller counties, a single district court handles all types of cases. In rural areas, as many as five counties share a single district court; urban counties.
