Rockingham County is New Hampshire's second-most populous county with roughly 320,000 residents, forming the southeastern portion of the state along the Massachusetts border and the Atlantic coast. Salem, Derry, Londonderry, Exeter, Hampstead, and Portsmouth are major Rockingham County communities. The county's southern border with Essex and Middlesex counties in Massachusetts means a substantial portion of Rockingham County residents commute to the Boston metro, have prior Massachusetts addresses, and may have Massachusetts court records that are as or more substantive than their New Hampshire records.
New Hampshire's court portal at courts.nh.gov provides statewide name search access covering Rockingham County Superior and Circuit Courts without pre-selection. The Rockingham County Superior Court is located in Brentwood. For the broader New Hampshire context including the Hillsborough County two-courthouse structure, see our New Hampshire state guide.
