Criminal Cases in the Mercer County Courts
Mercer County criminal cases begin in one of five Magisterial District Court areas. Those courts handle preliminary arraignments and hearings, summary matters, and lower-level work allowed by Pennsylvania law. If the Commonwealth shows a prima facie case at a preliminary hearing, the matter is held for the Court of Common Pleas. That phrase means there was enough evidence to continue the prosecution. It is not a conviction. Mercer County is Pennsylvania's 35th Judicial District, and the Common Pleas criminal docket uses county code 43.
The Mercer County District Courts directory maps the five local offices and their territories. The directory image below helps distinguish these Magisterial District Courts from federal district court. A Mercer County case may have an originating MDJ docket and a later CP-43-CR docket. Search both layers to follow the whole public trail.
The district map is the routing key when a preliminary record or paper file must be requested from the court that created it.
Search Mercer County CP-43 Cases
The free Unified Judicial System Case Search is the first stop for a filed Mercer County criminal case. It covers both Common Pleas and Magisterial District dockets. Name search works when no number is known, but common names need care. Set the court type, criminal case type, and Mercer County filter, then compare the filing date and other public identifiers. A Common Pleas number follows the pattern CP-43-CR-#######-YYYY.
The official UJS search screen shown below is a court index, not a Pennsylvania State Police background check. It can reveal charges that were later dismissed, withdrawn, amended, or nolle prossed. Read the downloadable docket sheet before treating a search-result label as the outcome.
The portal lets a reader move from a name result to the docket chronology, charge rows, court events, and public financial entries.
How to Search Case Records
A sound Mercer County case search follows the record rather than stopping at the first name match. The docket number is the strongest key. When it is unavailable, use the legal spelling and narrow the court, county, case type, and filing span. The Clerk of Courts supplies documents that the portal does not offer as a download.
- Open UJS Case Search and select either Court of Common Pleas or Magisterial District Court.
- Choose criminal case type, set Mercer County, and search by docket number or participant name.
- Match the county code, caption, filing date, originating court, and public subject details.
- Open the docket sheet and read each charge, event, and final disposition.
- Ask the proper MDJ office or Mercer County Clerk of Courts for an unavailable filing or certified copy.

Mercer County Clerk Record Requests
The Mercer County Clerk of Courts keeps Common Pleas criminal files in Suite 112 of the Mercer County Courthouse, 125 South Diamond Street, Mercer, PA 16137. The public counter is open weekdays from 8:30 a.m. to 4:30 p.m., except holidays. Call 724-662-3800, extension 2248, about file and copy procedure. Court Administration, in Suite 310, handles scheduling questions and asks callers to have the caption and case number ready.
The official Clerk of Courts page shown below confirms that this office is the filing custodian for criminal matters, summary appeals, bail-bonding applications, and certain district-court dispositions. A visitor seeking a filed case should not start at the jail. The jail answers present-custody questions, while the clerk answers case-file questions.
The local written-request form asks for the court, caption, docket number if known, exact documents, contact information, date, and preferred form of access.
What the Case File Shows
A docket sheet is the index and timeline of a Mercer County prosecution. It identifies the court, status, judge, originating MDJ matter, arresting agency, and complaint number. Charge rows list the offense, statutory section, grade, date, and disposition. Bail, lawyers, scheduled events, entries, assessments, payments, and balances can also appear. Full Social Security numbers and protected personal data are not public.
Underlying papers may include the complaint, criminal information, motion, order, plea material, or sentencing sheet. Those papers are not always free online. The following inventory separates the public docket summary from documents that may require a specific clerk request.
| Case Number & Court | The CP-43 or MDJ number, filing court, status, filing date, and assigned judge. |
|---|---|
| Charging Document | The complaint starts the case; the later criminal information may revise the filed counts. |
| Docket Entries | A dated chronology of filings, hearings, rulings, pleas, trial activity, and post-sentence events. |
| Hearing Dates | Preliminary, arraignment, pretrial, motion, plea, trial, sentence, and review events when scheduled. |
| Disposition & Judgment | The outcome for each count, including conviction, acquittal, dismissal, withdrawal, or nolle prosequi. |
| Sentence & Conditions | Incarceration, probation, and other terms imposed after a conviction. |
Note: A case can contain both conviction and non-conviction counts, so the charge-level disposition is more precise than the overall status.
Read Mercer County Case Dispositions
Mercer County docket terms describe procedural steps, not personal character. “Held for court” means the preliminary threshold was met. “Waived for court” means the defendant waived that hearing. Neither term is a conviction. “Nolle prossed” means the prosecution chose not to proceed on that count, while withdrawn, dismissed, and not guilty are also non-conviction outcomes reached in different ways. Bail is release status, not punishment.
The Mercer County District Attorney page provides the local prosecution-office context shown below. The DA reviews charges after the first complaint, which helps explain why a booking allegation may differ from the criminal information or final docket. The public case file, not the initial arrest wording, records that change.
When a disposition seems unclear, request the order or sentencing sheet from the Clerk of Courts instead of guessing from an abbreviated entry.
Stages of a Criminal Case
A Mercer County criminal case can span two dockets. The complaint begins at a Magisterial District Court. After preliminary arraignment, the judge addresses bail and schedules a preliminary hearing. A matter that is held or waived for court proceeds to Common Pleas, where the DA may file a criminal information. Formal arraignment, pretrial work, motions, and plea or trial events follow. The judge records the disposition and, after a conviction, imposes sentence.
Case flow: Charges Filed › Arraignment › Pretrial › Plea or Trial › Disposition › Sentencing
Mercer County's published calendar also names call-of-the-list, criminal omnibus motions, summary and license appeals, jail reviews, and sentence court. These labels explain why two entries close in date can serve different purposes. A weekly jail review is not the same event as sentence court.
Mercer County Specialty Court Calendar
The 2026 Mercer County court calendar includes Treatment Court, Veterans' Court, and Mental Health sessions alongside the regular criminal schedule. A specialty-court entry can mark structured treatment, review, or supervision work. It should not be read as a new arrest or a second conviction. The calendar also groups criminal trial blocks, arraignments, sentence dates, omnibus motions, and calls of the list, so a gap between docket events may reflect the court's scheduled cycle.
The Mercer County judges page shown below identifies the active Common Pleas bench. The docket's assigned-judge field and event list remain the best case-specific sources, since the public calendar describes court operations rather than the result of one prosecution.
The court calendar adds context, but only a filed order or docket entry establishes what happened in an individual Mercer County case.
Access & Restrictions
Pennsylvania judicial access policy, rather than an ordinary county Right-to-Know request, governs Mercer County court records. Public UJS dockets omit full Social Security numbers and other confidential personal identifiers. Juvenile files, victim information, sealed warrants, and protected investigative material also receive special treatment. Expunged, sealed, and Clean Slate limited-access cases do not appear in public Case Search, though authorized agencies may retain access where law permits.
The Mercer County judicial access policy page shown below links the written access and clerical-correction forms. A missing public name result does not establish that no proceeding ever existed. It may reflect limited access, a spelling difference, a different court layer, or an older filing that requires clerk help.
The policy route keeps court requests with the judicial custodian instead of misrouting them to the county's general Open Records Office.
Correct Mercer County Case Record Errors
Start by identifying which record is wrong. A typo or misplaced entry on a Mercer County docket may fit the local clerical-correction process. A disputed legal ruling, charge, or sentence is not just a clerical mistake and may require a court filing or order. If the court docket is accurate but Pennsylvania State Police repository data is not, obtain the docket and a certified disposition, then use the PSP Access and Review and challenge process.
Under Pennsylvania's Criminal History Record Information Act, an agency that detects inaccurate criminal-history data must correct its own record and notify recipients, including the Central Repository, within 15 days. UJS and PATCH can still differ because they serve different purposes and update through different paths. The broader Mercer County criminal history overview explains the PSP repository channel. For the court side, keep the CP-43 or MDJ number, note the exact wrong field, and ask the named custodian for the current procedure.
