What Are Public Records in Mercer County?

Public records in Mercer County are defined under the New Jersey Open Public Records Act (N.J.S.A. § 47:1A-1) as any government record made, maintained, kept on file, or received by a public agency in the course of its official business. Members of the public may inspect or obtain copies of these documents subject to the exemptions established by state law.

The following categories of records are currently available through various Mercer County offices:

Court records — Civil, criminal, probate, and family court documents are maintained by the Mercer County Superior Court. Members of the public may find civil and criminal case information through the New Jersey Courts online portal.
Property records — Deeds, mortgages, liens, and property transfers are recorded and maintained by the Mercer County Clerk's Office.
Vital records — Birth, death, and marriage certificates are issued by the New Jersey Department of Health and local municipal registrars. Divorce records are held by the Superior Court.
Business records — Trade name registrations, business licenses, and fictitious name filings are maintained by the Mercer County Clerk's Office and the New Jersey Division of Revenue.

Is Mercer County an Open Records County?

Mercer County fully complies with New Jersey's statewide open records framework, which establishes a broad presumption of public access to government documents. Under N.J.S.A. § 47:1A-1, government records shall be readily accessible for inspection, copying, or examination by the citizens of New Jersey. The statute further provides that any limitations on access must be construed narrowly, with the burden of proof resting on the government agency seeking to deny access.

New Jersey's Open Public Records Act (OPRA), enacted in 2002 and subsequently amended, requires all public agencies — including Mercer County departments, boards, and authorities — to designate a custodian of records responsible for processing requests. Agencies are generally required to respond to records requests within seven business days of receipt.

Mercer County additionally operates in compliance with the New Jersey Open Public Meetings Act (N.J.S.A. § 10:4-6 et seq.), commonly referred to as the "Sunshine Law," which mandates that meetings of public bodies be open to the public and that adequate notice be provided in advance. Meeting minutes and related documents are subject to public inspection under both OPRA and the Sunshine Law.

How to Find Public Records in Mercer County in 2026

Members of the public may obtain Mercer County public records through several official channels, depending on the record type sought.

Submit an OPRA request in writing — Requestors must complete an OPRA request form and submit it to the designated records custodian of the relevant agency. Forms are available at each agency's public counter or on the agency's official website.
Visit the agency in person — Many records are available for immediate inspection during regular business hours at the office that maintains them. No appointment is required for routine inspection of non-restricted records.
Request records by mail — Written requests may be mailed to the appropriate custodian. Requestors should include a clear description of the records sought, preferred format, and return mailing address.
Use online portals — Court case information is searchable through the New Jersey Courts case lookup system. Criminal case records may be accessed through the PROMIS/Gavel public access portal. Property records and tax data are available via the New Jersey transparency portal.

Requestors are not required to state the purpose of their request for most public records. Agencies may not condition access on the disclosure of the requestor's identity or intended use, except where specifically authorized by statute.

How Much Does It Cost to Get Public Records in Mercer County?

Current fees for public records in Mercer County are governed by N.J.S.A. § 47:1A-5, which establishes the maximum charges a public agency may impose for records reproduction.

$0.05 per page for letter-size (8.5" × 11") copies
$0.07 per page for legal-size (8.5" × 14") copies

Who Can Request Public Records in Mercer County?

Any person may request access to public records maintained by Mercer County agencies, regardless of residency, citizenship, or stated purpose. Under N.J.S.A. § 47:1A-1, the right of access to government records is extended broadly to citizens of New Jersey; however, courts and agencies have generally interpreted OPRA to permit requests from non-residents as well.

Key eligibility provisions include:

Residency is not required — Non-residents of New Jersey and Mercer County may submit records requests
Identification is generally not required — Requestors are not obligated to provide personal identification for routine records requests
Purpose need not be stated — Agencies may not require requestors to explain why they seek a particular record, except in limited circumstances authorized by statute
Requesting your own records — Individuals seeking records pertaining to themselves may be entitled to access records that would otherwise be restricted to third parties, subject to identity verification procedures
Restrictions for specific record types — Certain records, such as juvenile court files, adoption records, and sealed court documents, are restricted regardless of the requestor's identity or relationship to the subject

Organizations, businesses, and legal representatives may also submit records requests on behalf of clients or constituents.

What Records Are Confidential in Mercer County?

Not all government records in Mercer County are subject to public disclosure. New Jersey law establishes numerous categories of exempt records under N.J.S.A. § 47:1A-9 and related statutes. Agencies are required to apply a balancing test in certain circumstances, weighing the public interest in disclosure against the individual's right to privacy.

Records currently exempt from public disclosure include:

Sealed court records — Documents sealed by judicial order are not available for public inspection
Juvenile records — Records pertaining to juvenile delinquency proceedings are confidential under New Jersey court rules
Ongoing investigation records — Law enforcement records compiled for active criminal investigations are exempt to the extent that disclosure would interfere with the investigation
Personal identifying information — Social Security numbers, financial account data, and similar identifiers are redacted from disclosed records
Medical records — Health information protected under the federal Health Insurance Portability and Accountability Act (HIPAA) is exempt from disclosure
Adoption records — Records pertaining to adoption proceedings are sealed by statute
Child welfare and protective services records — Records maintained by the Division of Child Protection and Permanency are confidential
Personnel records — Employee personnel files are exempt, with limited exceptions for certain public employees
Trade secrets and proprietary business information — Commercially sensitive information submitted to government agencies in confidence is protected from disclosure
Security plans and critical infrastructure details — Documents relating to the security of public facilities and infrastructure are exempt from OPRA

Agencies denying access to records must provide a written statement citing the specific statutory basis for the denial. Requestors who believe a denial is improper may file a complaint with the New Jersey Government Records Council or seek relief in Superior Court.
