A county court is a court based in or with a jurisdiction covering one or more counties, which are administrative divisions (subnational entities) within a country, not to be confused with the medieval system of county courts held by the High Sheriff of each county.
Since 2014, England and Wales have had what is officially described as "a single civil court" named the County Court, with unlimited financial jurisdiction. However it should be understood that there are County Court buildings and courtrooms throughout England and Wales, not one single location. It is "a single civil court" in the sense of a single centrally organised and administered court system. Before 2014 there were numerous separate county court systems, each with jurisdiction across England and Wales for enforcement of its orders, but each with a defined "county court district" from which it took claims. County court districts did not have the same boundaries as counties: the name was used because the county courts had evolved from courts which did in fact correspond to a county's territory. Today the court sits in many County Court centres, currently corresponding to the old individual county courts.
County Court matters can be lodged at a court in person, by post or via the internet in some cases through the County Court Bulk Centre. Cases are normally heard at the court having jurisdiction over the area where the claimant lives. Most matters are decided by a district judge or circuit judge sitting alone. Civil matters in England (with minor exceptions, e.g. in some actions against the police) do not have juries. Judges in the County Court are either former barristers or former solicitors, whereas in the High Court they are more likely to have formerly been a barrister.
Civil claims with an amount in controversy under £10,000 (the Jackson Reforms have increased this from £5,000) are dealt with in the County Court under the small claims track (sometimes known to the lay public as "small claims court," although it is not a separate court). Claims between £5,000 and £25,000 (£15,000 for cases started before April 2009) that are capable of being tried within one day are allocated to the "fast track" and claims over £25,000 (£15,000 for cases started before April 2009) to the "multi track." These 'tracks' are labels for the use of the court system - the actual cases will be heard in the County Court or the High Court depending on their value. For personal injury, defamation, and some landlord-tenant dispute cases the thresholds for each track have different values.
