Middlesex County, New Jersey
Middlesex County · New Brunswick · the third-most-populous county still hires a county
New Brunswick is the seat. Middlesex Massachusetts is a different state.
Middlesex is a Central Jersey county on the Raritan River, one of the original counties, created 1683. New Brunswick is the seat. It is not the capital. Trenton is the capital of New Jersey and sits in Mercer. Middlesex County, Massachusetts, is a different state. Newark is Essex. Jersey City is Hudson. Flemington is Hunterdon.
Twenty-five municipalities include New Brunswick, Perth Amboy, Edison, Woodbridge, Piscataway, East Brunswick, Old Bridge, South Brunswick, Sayreville, North Brunswick, Monroe, and the rest. New Brunswick is this county. Trenton is Mercer. Jersey City is Hudson. Cambridge is Massachusetts.
This page is Side One for the place. The Sheriff’s job — Civic Square court security, process, not the North Brunswick jail — is taught at Office of the Sheriff — Middlesex County.
Seven Commissioners, no County Executive
Middlesex is governed by a Board of County Commissioners of seven, elected at-large on a stagger. There is no County Executive. The board reorganizes each January. That is not Mercer’s Executive map. That is not Hudson’s Executive-plus-Register map. That is not Hunterdon’s five.
The Sheriff is a constitutional officer, three years, Article VII, Section II, paragraph 2. The board does not hire this badge. Last regular sheriff general was 4 November 2025. Next regular is Tuesday, 7 November 2028. Tuesday, 3 November 2026 is not this oval. Mercer — the capital — is 2026. The Governor is 2029.
Raritan and the Turnpike, not the Hudson
The Raritan River, the Garden State Parkway, the New Jersey Turnpike, Route 1, and Route 18 are this land. Rutgers sits in New Brunswick. It is not the county hall. No PATH as the county story. No gold capitol dome as the county hall — that dome sits in Mercer. Staff who paste Cambridge, Massachusetts, onto Civic Square are on the wrong county.
How a Raritan public actually files a paper
Each municipality has a site. Edison’s site does not speak for Perth Amboy. The Sheriff’s listing speaks for court, process, warrants, and transport. The Adult Correction Center at Route 130 and Apple Orchard Lane, North Brunswick, is Office of Adult Corrections — a Warden, not this Sheriff — since 1978. The County Clerk lists at 75 Bayard Street, New Brunswick. Do not send a Woodbridge family to Trenton for a county paper. Do not send them to Cambridge for a New Jersey writ.
Civic Square court, a jail in North Brunswick that is Corrections
Crime in New Brunswick is often New Brunswick Police. Crime in Edison is often Edison Police. New Jersey State Police is the state. Civil process, Superior Court security at 56 Paterson Street and 120 New Street, sheriff sales, and fugitive work are this Sheriff. Jail as a local house is North Brunswick Adult Corrections. Rights do not change at the Plainsboro line. Remedy for city police is the City. Remedy for a Sheriff’s paper is the Sheriff. Relief when the Raritan floods New Brunswick is this count first.
A student who stays on Livingston Avenue
A student uses town pages, the county jobs board, or the Sheriff’s official listing at 701 Livingston Avenue. Rutgers is a campus. It is not the jail. Outreach that only knows one campus is not doing Cranbury or Helmetta.
