Lake County offices and records

Sheriff & Law Enforcement. Lake County Sheriff's Office is responsible for maintaining law and order in Lake County, particularly in unincorporated areas.

Police Departments. Lake County is served by several law enforcement agencies, including Lake County Sheriff's Office and municipal police departments such as the Waukegan Police Department, Highland Park Police Department, and Lake Forest Police Department. Each city department is responsible for maintaining public safety within its jurisdiction, handling local crimes, and coordinating with the Sheriff's Office on major investigations.

Law Enforcement & Arrests. Lake County Sheriff's Office, headquartered at 25 South Martin Luther King Jr. Avenue, Waukegan, IL 60085, is the primary law enforcement agency for unincorporated areas and provides countywide services including corrections, court security, and civil process. Inmates can be located through Lake County Sheriff's website at www.lakecountyil.gov/2032/Locate-an-Inmate, which features an online inmate locator allowing searches by name, booking number, or date. Arrest records in Lake County are considered public records under the Illinois Freedom of Information Act (5 ILCS 140/1 et seq, FOIA), which requires government agencies to provide access to public records upon request unless specifically exempted.

Arrest Records. Arrest records in Lake County are maintained by Lake County Sheriff's Office and the various municipal police departments within Lake County.

Mugshots & Booking Photos. Mugshots in Lake County are taken and retained by Lake County Sheriff's Office during the booking process. These booking photos are part of the public record and can be accessed through the Sheriff's Office website or by submitting a formal request.

Is an old working under a property here?

The mine records hold 20 named mine sites inside the county, 14 of them worked out or abandoned; the old survey maps add 66 holes drawn inside the county, 0 of them shafts or tunnels. The minerals the records name are construction sand and gravel; Stone; crushed stone.

A point in either file is a location, not a property line: the sheet shows the opening on the surface, not the rooms under it. The record that shows what runs under a parcel is the mine map. The OSMRE National Mine Map Repository holds scanned underground mine maps and answers requests for a named mine or an area. The Illinois Mine Subsidence Insurance Fund is a not for profit created by statute, not a state agency; the cover is bought through the homeowner insurer.

Lake County records, certification and office responsibilities

A court result and a court document

Begin a judicial search through the Circuit Clerk and preserve the case number, case type and document date. A docket can identify an action without reproducing the signed order. Restricted proceedings and documents require an appropriate access basis even when related case information appears in a search.

The document-copy request form asks for the case number, title and requested document. It directs storage-file inquiries to a separate retrieval request. If the record is older, identify the filing date and ask whether the file is in storage before planning to collect it. A request for an entire file can produce a different cost and delivery process from a request for a named judgment.

Electronic certification and raised seals

The certified-copy instructions describe Clerk E-Certify access for unrestricted cases and documents, with separate verified access for qualifying parties and attorneys. Older bulk scans may appear under a generic document-image label. If the particular order is inside such a scan, the clerk provides a process for identifying that image instead of requiring an indiscriminate whole-file order. The same instructions say that documents intended for an Illinois apostille need a raised seal and direct requesters to the Records Department before ordering. They also state that, effective May 1, 2026, the clerk no longer forwards eviction-enforcement requests to the sheriff. Obtaining the certified order and submitting an enforcement request are therefore separate steps. Confirm the receiving organization's requirements before selecting electronic certification.

Court offices and probate service

The Circuit Clerk location directory identifies the main office in the lower level of the courthouse and administrative complex at 18 North County Street, Waukegan, Illinois 60085. Posted weekday hours are 8:30 a.m. to 5 p.m. It lists a separate Probate Division at 847-377-3260 and Records Division at 847-377-3211, as well as branch courts.

A probate request should specify the decedent, estate or guardianship file and the document needed. A will, letters of office and an order approving an account are different records. The correct branch or division also matters for a traffic, juvenile or civil inquiry; a countywide court name does not guarantee that every counter has the file in hand.

Recording Division and fee classes

Land instruments belong to the County Clerk's Recording Division rather than the Circuit Clerk. Search for the recorded deed, mortgage, lien or release using the parties and recording reference. Compare the full instrument with the parcel description and any related instruments identified in it.

The recording and copy schedule lists a $70 standard-document recording charge and $82 for a nonstandard document, with separate exempt-government and lien categories. Those are document-class charges. Ordinary recorded-document copies cost $1 per page, while plats cost $5 per page. Do not plot the flat recording charge as a first-page copy price or use a plat-copy price for an ordinary deed.

Certified copies and genealogy products

The county birth-record page lists $10 for the first certified copy and $4 for each additional copy. Its genealogy product is separate from a certificate accepted for official identity purposes. Follow the eligibility and identification instructions for the product requested, and identify the event location before ordering.

For death records the county lists $14 for the first certified copy and $8 for each additional copy. The marriage-record service lists $10 for the first certified copy and $4 for additional copies. A new marriage license and a copy of a recorded marriage are separate transactions. Keep the record type and additional-copy conditions attached to each price.

Assessment questions and payment questions

The Chief County Assessment Office works with township assessment information. Establish the parcel and assessment year before asking about characteristics, exemptions or a valuation concern. The Treasurer handles tax-payment matters, which should not be confused with changing an assessment.

A recorded deed, property record card and tax receipt should be cited separately. None alone establishes that a proposed building use is allowed. Permit and land-use inquiries need the municipality or county department with authority over that parcel. Supply the address, parcel identifier and approximate application or construction date.

Sheriff and jail records

Use the Sheriff's Office for its incident, civil-process and administrative records, and the inmate-information route for current jail questions. A municipal agency retains reports it created. State which agency handled the incident and include the report number or a useful event description.

A booking entry can help identify a case but does not establish conviction or the final disposition. A court order and a jail status report reflect different events and can change at different times. If you need proof of an outcome, request the filed judgment or disposition from the Circuit Clerk.

Administrative requests and statutory limits

The county's record-custodian guide explains which offices maintain particular record categories and states that a FOIA request is not required to view ordinary recorded land documents. Use the record-specific service when it already provides the document.

For ordinary administrative FOIA requests, Illinois section 3 sets an initial 5-business-day response period and allows a qualifying 5-business-day extension. Different statutory request categories can have different procedures. The fee provisions address eligible public-interest reductions. Identify the requested records and format, and ask for an estimate for substantial reproduction. Other state resources appear in the Illinois records guide.
