Mercer Island Overview
King County Superior Court and Mercer Island Felony Cases
All felony charges connected to Mercer Island are filed with King County Superior Court. Mercer Island has no superior court of its own. Class A, B, and C felonies -- assault, robbery, drug offenses, weapons charges -- are all handled at the county level. King County Superior Court covers all cities and communities within the county, including Mercer Island.
King County uses the KC Script online portal for public case searches. You can look up cases by name, case number, or filing date. The portal displays case status, charges, hearing dates, and party names. Searching is free. Cases usually appear in the system shortly after filing. This is the best first tool for finding a Mercer Island felony case online.
For certified copies of court records, contact the King County Superior Court Clerk. Copies are $0.50 per page. Certified copies carry an extra fee. You can request records in person at the Seattle courthouse or by mail. Include the case number if you have it. The clerk can search by name for a fee if you do not have a case number.
The Washington Courts statewide name search is shown below. The WA Courts name search portal covers courts across the state and lets you check records in multiple counties at once.
The statewide search is useful when you do not know which county filed a case, or when checking whether a person has records in more than one county.
Mercer Island Police Records
The Mercer Island Police Department maintains arrest records, incident reports, and related documentation for activity within city limits. These records are separate from court records held by King County Superior Court. An arrest does not mean a conviction. Court records tell you what happened after the arrest.
To request police records, contact the Mercer Island Police records office. The records contact is Shelby Pattajo. You can reach the records unit by email at mi-records@mercergov.org or by phone at (206) 275-7610. The Mercer Island Police records page provides full details on how to submit a request and what types of records are available.
Some records may be withheld if they involve an active investigation or if releasing them would conflict with the privacy protections in RCW 10.97, Washington's criminal records privacy law. The records unit can tell you what is and is not available for a specific request.
For city records outside of law enforcement, the Mercer Island public records page handled through the City Attorney's office is where you go. The Records Officer is Mary Swan. You can reach her at prr@mercerisland.gov or (206) 275-7651.
The city's public records process covers city-generated documents. Court case records and police arrest records are handled by separate offices.
Mercer Island Municipal Court
Mercer Island Municipal Court handles misdemeanors, gross misdemeanors, and traffic matters. Felony cases do not go through municipal court. The Mercer Island Municipal Court is located at Newcastle City Hall, not on Mercer Island itself. This is worth knowing if you need to appear in court or submit records requests to the right location.
Visit the Mercer Island Municipal Court page for hours, contact information, and procedures. If you are searching for records from a traffic case or a misdemeanor charge in Mercer Island, this is the court that holds those files.
If you are unsure whether a case is at municipal court or superior court, check the type of charge. Felonies go to King County Superior Court in Seattle. Everything lower than a felony goes to municipal court.
WATCH System for Washington Conviction History
Washington's WATCH system gives you statewide access to conviction records. WATCH stands for Washington Access To Criminal History. The WATCH portal is run by the Washington State Patrol and draws from the WSP criminal history database, which is built from court submissions, fingerprints, and law enforcement reports from agencies around the state.
A name search costs $11.00. Pay by credit card. The system shows felony and serious misdemeanor convictions recorded in Washington. Pending charges and arrests without convictions are not included. WATCH covers all Washington counties, so you get a full statewide picture without searching each county separately.
The WSP Criminal History Records division runs a more detailed background check process for individuals and agencies. This option takes longer but may return more complete results for formal requests.
Washington's criminal records privacy law at RCW 10.97 limits what criminal history can be released to the public and how it may be used. WATCH follows those rules and only returns legally available information.
The WSP WATCH portal is shown below. Visit watch.wsp.wa.gov to run a name check for Mercer Island or any other location in Washington state.
WATCH is a useful first step when you want a broad view of someone's Washington record before looking at specific county case files.
Vacating Mercer Island Felony Convictions
Some people can vacate their Washington felony convictions under RCW 9.94A.640. A vacated conviction is removed from the public court record, though law enforcement may keep their own internal records. Not every felony is eligible. Class A felonies, sex offenses, and most violent crimes do not qualify.
For Class B and C felonies, eligibility requires completing the full sentence, paying all fines and restitution, and meeting the required waiting period without new convictions. The waiting period varies based on the offense class and discharge date.
To petition for vacation of a Mercer Island felony conviction, you file in King County Superior Court. The court notifies the prosecutor and sets a hearing. If the court grants the motion, the clerk updates the record. After vacation, changes should appear in the WATCH system and the court's public database. Legal aid resources in King County can help people who cannot afford an attorney.
Warrant Searches and Older Records
To check for active DOC warrants in Washington, the DOC warrant search tool is a solid starting point. The Washington Department of Corrections maintains this tool for people under DOC supervision. Not all warrant types appear in the system, but it covers many active DOC supervision warrants.
For older Mercer Island case records, the Washington Digital Archives holds historical state and county records. Not all court files are digitized. Contact the King County Superior Court Clerk to ask whether older Mercer Island case files have been moved to archive storage before making a formal request.
Active King County case information -- hearing dates, case status, charges -- is available through the KC Script portal and the statewide Washington Courts search. If a case is active, these tools usually show current status without needing to call the court directly.
