To look up who owns a property, start with the county tax assessor’s website for the county where the property sits. Search by street address or parcel number, and the current owner of record usually appears within a minute or two, along with the mailing address the county uses for tax bills. If you need legal proof of ownership rather than a quick name, the county recorder or register of deeds holds the actual deed. Property ownership in the United States is public record, so both offices are open to anyone, and most now offer free online search portals.
What You Need Before You Search
Gather at least one reliable identifier. A street address with city and zip code works for most databases. For vacant land or property without a standard address, you’ll want the Assessor’s Parcel Number, a unique code the county assigns to every tract for tax purposes. You can find the parcel number on a prior tax bill or by calling the assessor’s office and describing where the property sits.
Confirm the county before you search. Unincorporated areas sometimes fall under a different jurisdiction than the mailing address suggests, and searching the wrong county returns nothing. Double-check street name spellings too.
Start With the County Tax Assessor
This is where most searches should begin. Every county maintains a tax roll listing all taxable parcels, their assessed values, and the name of whoever is responsible for property taxes. The vast majority of assessor offices offer a free online search where you type in the address or parcel number and get an immediate result. Expect to see the current owner of record, their mailing address, the property’s assessed value, and often the most recent sale date and price.
Assessor records exist for tax collection, so the name listed is whoever the county sends the bill to. That’s usually the legal owner, but not always. A property held in a trust may list the trustee rather than the beneficiary. Assessor data can also lag behind recent sales by weeks or months, because the office updates records only after a new deed is recorded and processed. Treat what you find as a strong lead, not definitive legal proof.
Check the County Recorder for Legal Ownership
The assessor tells you who pays the taxes. The recorder’s office tells you who legally owns the property. This is where deeds, mortgages, liens, and other instruments affecting title are officially filed. When a property changes hands, the new deed gets recorded here, creating a chain of ownership that can stretch back decades.
Recorder offices maintain indexes organized by the names of buyers and sellers. Many counties also let you search by address or parcel number. The document you want is the most recently recorded deed, which identifies the current owner, describes the property, and shows when the transfer occurred. Most counties offer at least a basic version of this search online for free.
If you want an official certified copy of the deed rather than just a screen view, expect a fee. Charges vary, but commonly run several dollars for the first page and a few dollars for each additional page, or a flat per-document fee. You can usually request certified copies in person, by mail, or through an online ordering system.
Liens and Other Encumbrances
The recorder holds more than deeds. Mortgage liens, mechanic’s liens from unpaid contractors, judgment liens from lawsuits, and notices of federal tax liens filed by the IRS all appear in the same records. A federal tax lien attaches to all of a taxpayer’s property after the IRS assesses a liability, sends a bill, and the taxpayer fails to pay. The IRS files a public Notice of Federal Tax Lien to alert other creditors.1Internal Revenue Service. Understanding a Federal Tax Lien These filings matter if you’re thinking about buying, because liens can survive a sale and become the new owner’s problem.
Use GIS Parcel Maps When You Don’t Have an Address
Most counties maintain Geographic Information System maps that overlay property boundaries on aerial imagery. You can zoom into a neighborhood, click a parcel, and pull up the owner’s name, parcel number, lot dimensions, and often assessment data or sale history. County planning departments and assessor offices host these maps on their websites at no charge.
GIS maps are especially useful when you can see the property but don’t know its address. Standing at a vacant lot or a neighbor’s fence line, you can find the parcel by its physical location rather than a street number. The underlying data comes from the same assessor records, so the same lag caveats apply.
Free Property Aggregator Sites
Zillow, Realtor.com, Redfin, and other property-search platforms pull data from county records and present it in a friendlier format than most government portals. They often display the owner’s name, purchase price, tax assessment, and basic property details, and they let you search across county lines without figuring out which office covers each jurisdiction.
The trade-off is accuracy. Aggregators scrape and repackage public records, so their data can be outdated, incomplete, or wrong. Fine as a starting point for casual curiosity. Not fine for anything with legal or financial stakes. Always confirm what you see against the county assessor or recorder directly.
When the Owner Is an LLC or a Trust
A deed naming “123 Main Street LLC” or “The Smith Family Trust” doesn’t tell you much about the actual person behind the entity. This is increasingly common. Many real estate investors, and plenty of individual homeowners, hold property through LLCs or trusts for liability protection or estate planning.
LLCs
Every LLC must register with a state, and every state offers a free online business entity search through its Secretary of State’s office. Search for the LLC’s exact name, and the filing typically shows the registered agent, the entity’s formation date, and its status. The registered agent is the person or company authorized to receive legal documents on the LLC’s behalf. In smaller operations the registered agent is often the actual owner. Larger entities frequently use a professional registered agent service, which adds another layer to peel back.
The federal beneficial ownership registry won’t help for domestic companies. In March 2025, FinCEN issued a rule exempting all U.S.-created entities from reporting their beneficial owners under the Corporate Transparency Act. Only foreign-formed entities registered to do business in a U.S. state must now file.2Financial Crimes Enforcement Network (FinCEN). Beneficial Ownership Information Reporting For domestic LLCs, the Secretary of State search remains the best free option.
Trusts
Trusts are harder to trace because they don’t register with the state the way businesses do. A deed held by a trust names the trustee, not the beneficiary. If the deed reads “John Smith, Trustee of the Smith Family Trust dated January 1, 2020,” John Smith is your point of contact, but he may be managing the property for someone else. Trust documents themselves are private and not filed in any public database. Short of asking the trustee directly or finding a court filing that names the beneficiaries, there’s often no free public method to identify who actually benefits from trust-held property.
Federal and Tribal Land
Standard county records don’t cover land owned by the federal government or held in trust for Native American tribes. These require separate searches.
The Bureau of Land Management operates the General Land Office Records database, which contains historical land patents and survey records for federal land transfers. You can search by state, county, township, and range to find records of when land passed from federal ownership into private hands.3Bureau of Land Management. Search – BLM GLO Records This is most useful for tracing an original chain of title or confirming whether land was ever formally conveyed out of federal ownership.
For Native American trust and restricted lands, the Bureau of Indian Affairs maintains the official title records through its Branch of Land Titles and Records. The branch oversees 18 regional and tribal Land Titles and Records Offices that serve as the federal offices of record for Indian trust lands and issue certified Title Status Reports showing complete ownership and encumbrance information.4Indian Affairs. Branch of Land Titles and Records
When You Can’t Find a Name
Not every owner’s name is freely accessible. Most states operate address confidentiality programs that allow victims of domestic violence, stalking, sexual assault, and human trafficking to substitute a state-provided mailing address for their real one on public records. These programs exist in at least 45 states. Some states extend similar protections to law enforcement officers, judges, and other public officials who face safety risks tied to their home address.
When a property owner participates in one of these programs, assessor or recorder records may show a government P.O. box instead of a personal name and address. There’s no workaround, and that’s by design. If a record seems deliberately obscured, it likely exists for someone’s physical safety.
When To Pay for a Professional Title Search
When a free search isn’t enough, title companies offer professional reports that consolidate ownership, liens, and encumbrances into a single document. The most common product for a quick ownership check is an Ownership and Encumbrance report, which typically costs between $45 and $275 depending on the property’s location and complexity. A full title search, which traces the chain of title back several decades, is usually ordered through a title company or real estate attorney as part of a purchase transaction and costs more.
These reports are worth the cost when you’re making a financial decision based on what you find. County databases can have gaps. A lien indexed under the wrong name. A deed recorded in a neighboring county because of a boundary quirk. An old mortgage satisfaction that was never formally recorded. A title professional knows where to look for those problems and carries insurance against missing them. For casual curiosity, the free methods work fine. For buying property or lending money against it, a professional search is the standard of care.
