Hillsborough County is New Hampshire's most populous county, with roughly 430,000 residents containing Manchester (New Hampshire's largest city) and Nashua (the second-largest). The county generates the majority of New Hampshire's court filing volume and is the anchor of the state's southern population corridor that connects to the greater Boston metro via I-93 and I-95.
The most important operational detail for Hillsborough County records searches is the two-courthouse structure. Hillsborough County Superior Court has two separate locations — the northern division in Manchester serves communities in the northern part of the county, while the southern division in Nashua serves communities in the southern portion. Routing a records request to the wrong courthouse causes delays and missed results. New Hampshire's court portal at courts.nh.gov provides statewide coverage that resolves this automatically for initial case-level searches. For the broader New Hampshire context, see our New Hampshire state guide.

Hillsborough County Superior Court handles felony criminal cases and major civil matters. The Circuit Court (Family Division, District Division, Probate Division) handles misdemeanors, family matters, probate, and small claims. Both court levels have locations in Manchester and Nashua. The 2011 circuit court merger consolidated former district, probate, and family courts — both superior and circuit court records are accessible through courts.nh.gov.

Crime statistics and public-safety context
Manchester has New Hampshire's highest violent crime rate by volume, driven largely by the city's opioid crisis which has generated elevated drug-related court filings. Nashua has a substantially lower violent crime rate than Manchester despite similar population size, reflecting its more suburban character. Hillsborough County's overall court filing volume is the highest in New Hampshire by a wide margin. Source: New Hampshire Department of Safety, Crime in New Hampshire 2022.

The courts.nh.gov statewide portal handles this automatically for initial case-level searches.

Marriage licenses in Hillsborough County are issued by individual town clerks in each municipality — Manchester City Clerk, Nashua City Clerk, etc. The NH Department of Health and Human Services maintains a statewide marriage index from 1640 forward and a divorce index statewide.
