Illinois Property Records: How to Find Out Who Owns a Property (2026)

Illinois splits property recording between two different offices depending on the county. In 87 of the state's 102 counties, the County Clerk handles recording; in the rest, including Cook, Will, DuPage, Lake, and McHenry, a separately elected Recorder of Deeds does the job instead.

How Property Records Work in Illinois

Illinois property records are recorded and indexed at the county level, but which office does that job depends on the county's population, a detail that traces back to the state's 1870 Constitution. Under 55 ILCS 5/3-5018 and related provisions of the Illinois Counties Code, a separately elected Recorder of Deeds is constitutionally required only in counties with a population of 60,000 or more. Counties below that threshold are not required to maintain a standalone Recorder's office at all, and most have chosen not to: the county board can vote to fold the recording function into the County Clerk's office instead, one elected official handling both jobs.

As of recent counts, 87 of Illinois's 102 counties have consolidated recording into the County Clerk. The remaining, larger counties, including Cook, Will, DuPage, Lake, and McHenry, keep a distinct, separately elected Recorder of Deeds. This means the correct office to contact for a deed, mortgage, lien, or plat in Illinois genuinely depends on which county the property sits in, not just a naming convention. A reader in a smaller downstate county needs to look for the County Clerk; a reader in Cook County needs the Cook County Clerk's Recordings Division specifically (Cook County merged its Recorder of Deeds into the Clerk's office in 2020, but kept the recordings function as its own division).

Online access also varies sharply by county. Cook County offers a free online search of recorded land documents through its Recordings System (CRS) at crs.cookcountyclerkil.gov, searchable by Property Index Number (PIN) or grantor and grantee name. DuPage, Will, Lake, and McHenry counties each run their own recorder search portals, with some offering free index search and free or low-cost document images, and others, such as Will County's system, charging per document accessed. Smaller, consolidated-office counties may offer little or no online search, requiring an in-person or phone request to the County Clerk.

How to Find Out Who Owns a Property in Illinois

The fastest free way to identify a property's current owner in Illinois is usually the County Assessor's or GIS mapping tool, not the recorder's index. In Cook County, CookViewer at maps.cookcountyil.gov links directly to Assessor, Treasurer, and Board of Review property data, letting you search by address or PIN and see the owner of record along with assessed value. Lake County's Tax Parcel Viewer and Sangamon County's parcel search work similarly, letting you search by parcel number, owner name, or address depending on the county's tool.

If you need to trace prior owners, not just the current one, or confirm an actual recorded instrument, the next step is the county recorder's or clerk's grantor-grantee index, which lets you search by a person's name to find every deed, mortgage, or lien recorded against them in that county.

For a certified copy of a recorded deed, contact the Recorder or Clerk directly. Fees vary significantly by county under the framework of 55 ILCS 5/3-5018, and Illinois runs notably higher than most states in this cluster: Lake County charges $50.00 for a certified copy of a standard document ($62.00 for a non-standard document), and Cook County charges $55.00 for a certified standard document. Plain, non-certified copies are typically closer to $1 per page in most counties. Confirm the exact fee with the specific county recorder or clerk before requesting a copy, since these figures can change and vary by document type.

A reader researching multiple states should note that Illinois has no official state-run consolidated index; third-party aggregator sites exist but are private companies, not government portals. For the broader multi-state picture, see Property Records by State.

The 60,000-Population Threshold: Illinois's Clerk-vs-Recorder Quirk

This is the detail that most surprises people researching Illinois property records: the Recorder of Deeds is not a guaranteed office in every county the way it is in most states. Illinois's 1870 Constitution and the implementing statute, 55 ILCS 5/3-5018, set population as the trigger. Once a county crosses 60,000 residents, it is required to maintain a separately elected Recorder. Below that line, the county board has discretion, and the overwhelming majority have voted to eliminate the standalone office and shift recording duties to the County Clerk, generally to save the cost of maintaining a second elected office and separate staff.

The practical effect is that 87 of Illinois's 102 counties, the large majority by count though not by population, have no separate Recorder's office at all. A resident of one of those counties who searches for "Illinois County Recorder" and expects to find a distinct office will instead need to direct any recording request, whether it's a document search, a certified copy, or a question about a recording fee, to the County Clerk. Only the larger, more populous counties, Cook, Will, DuPage, Lake, McHenry, and a handful of others, retain the traditional standalone Recorder of Deeds.

This structural quirk also helps explain why certified-copy fees vary so much by county in Illinois. The larger counties with standalone Recorder offices, which handle far higher transaction volume, have generally set higher certified-copy fees, in the $50 to $62 range, compared to the far lower per-page fees typical in smaller, consolidated-office counties and in most other states nationally.

Deed Solicitation Mailers and Deed Fraud in Illinois

Illinois homeowners, like homeowners nationwide, regularly receive official-looking mail offering to sell a "certified copy of your deed" or a property assessment profile for a fee, often in the range of $80 to $95. These mailers are designed to mimic government correspondence, using language like "official" and "certified" and including real details about the property pulled from public records to appear legitimate. A disclaimer buried in small print typically states the mailer is not a government bill and there's no obligation to pay.

The actual certified copy costs far less when requested directly from the county. Even accounting for Illinois's higher-than-average certified-copy fees in counties like Cook and Lake, the direct county fee is still a fraction of what these solicitation mailers charge. If you receive one, the standard advice is to disregard it, not pay, and report it to the Illinois Attorney General's consumer protection office, the FTC at ftc.gov/complaint or 1-877-FTC-HELP, and the U.S. Postal Inspection Service if it arrived by mail.

A more serious concern is deed fraud, where a forged or fraudulent deed is filed to transfer ownership away from the real owner, often targeting vacant land or mortgage-free homes. The FBI's Internet Crime Complaint Center issued a Public Service Announcement in June 2026 describing how criminals use identity data pulled from public records and data brokers to impersonate real property owners. Cook County addresses this directly through its Property Fraud Unit, which helps homeowners investigate suspicious filings and coordinates with law enforcement, as documented by both the Cook County Clerk's office and Illinois Legal Aid Online. Will County Recorder of Deeds offers a free Property Fraud Alert enrollment and report line. Readers in other Illinois counties should check whether their local Recorder or Clerk offers a similar free notification service.

Not a Substitute for a Professional Title Search

A free or low-cost county records search answers the basic question of who owns a property right now, but it is not equivalent to a professional title search. Licensed title companies and closing attorneys search public land records, tax assessor records, and court documents together, then analyze the results for liens, missing heirs, and other defects. Industry estimates cited by state insurance regulators put the share of residential transactions with a title issue found this way at roughly 25 percent. Even a thorough professional search can only report what actually appears in the public record, which is why title insurance exists as a separate layer of protection alongside the search.

Anyone planning an actual Illinois property purchase, rather than a general ownership lookup, should work with a licensed title company or real estate attorney rather than relying solely on a self-directed county search.
