To find out who owns something, you go to the registry that tracks that type of asset: county recorder and assessor offices for real estate, state motor vehicle agencies for cars (with limits), the Coast Guard for documented vessels, the secretary of state for businesses, ICANN’s lookup tool for domain names, and the USPTO or Copyright Office for intellectual property. Most of these databases are free or inexpensive, and most of the hard part is knowing which one to open first.
Real Estate: County Assessor and Recorder
Property ownership starts at the county level. The tax assessor assigns every parcel an Assessor’s Parcel Number and ties that number to the current owner’s name and the property’s assessed value, because the office has to know where to send the tax bill. Most counties publish this through a free online portal searchable by address or parcel number.
The county recorder holds the deeper record: the chain of deeds showing every transfer over the property’s history. A grant deed names the grantor (giving up ownership) and the grantee (the new owner). A quitclaim deed does the same thing without any guarantee the grantor actually had clear title. Both are filed with the recorder and are public. Some counties let you view basic deed information online for free; others charge a small fee for certified copies.
When the Deed Names a Trust or LLC
If the deed lists a trust as the owner, the trust holds legal title and a trustee manages the property on behalf of beneficiaries whose names are not in the public record. The trust agreement itself is private. If an LLC appears on the deed, the entity owns the property, and you have to pivot to business filings to learn who controls that LLC. Layered ownership is common, and it’s one of the main reasons a deed search can raise more questions than it answers.
Liens on the Record
A deed search also surfaces liens recorded against the property. The most common is a mortgage lien, or deed of trust depending on the jurisdiction, which signals that a lender has a financial interest in the property as collateral. The borrower remains the legal owner on the deed, but the lien tells anyone researching that a lender can force a sale on default. Recorded liens also include tax liens, mechanic’s liens from unpaid contractors, and judgment liens from court cases. The record shows the parties and the property’s legal description. It won’t show loan balances or payment terms.
Vehicles and Vessels
Vehicle ownership works differently from real estate because public access is restricted by design. State motor vehicle agencies hold title records for every registered car, truck, and motorcycle, but most states don’t let the general public look up owners by license plate or VIN. Access to the owner’s name is typically limited to law enforcement, attorneys with a legitimate legal matter, insurers, and certain other authorized parties. If someone hit your parked car and you only have the plate, you generally have to go through the police or your insurance company.
What the public can access is the National Motor Vehicle Title Information System, a federally mandated database that tracks title status, brand history, odometer readings, and salvage or total-loss reports.1Office of the Law Revision Counsel. 49 USC 30502 – National Motor Vehicle Title Information System NMVTIS is built for used-car buyers. It will tell you whether a title is valid, whether it’s been branded salvage or flood-damaged, and the last reported odometer reading. It will not give you the owner’s name and address. Consumers access NMVTIS through approved third-party providers, and each report links to the relevant state’s full title record for further research. Coverage sits at roughly 87 percent of U.S. vehicles, so a clean report doesn’t guarantee a clean history.2Bureau of Justice Assistance. For Consumers – NMVTIS
Boats depend on size and use. Vessels documented by the federal government, generally those over five net tons used in coastwise trade or commercial fishing, are searchable through the Coast Guard’s PSIX Vessel Search by vessel name, hull identification number, or call sign.3United States Coast Guard. PSIX Vessel Search Smaller boats registered at the state level are handled by state wildlife or natural resources agencies, and access rules vary.
Businesses: Secretary of State Filings
To find the people behind a company, start with the secretary of state in the state where the business was formed. Most states require corporations, LLCs, and partnerships to register there, which makes the formation documents public.4U.S. Small Business Administration. Register Your Business Corporations file articles of incorporation, LLCs file articles of organization. Those documents show the entity’s legal name, formation date, stated purpose, and the registered agent.
The registered agent trips up a lot of first-time searchers. That’s the person or entity designated to accept legal papers like lawsuits on behalf of the business.5IN.gov. What Is a Registered Agent and Why Do I Need One? Plenty of businesses hire a third-party registered agent service that has no ownership stake at all. The name you see accepts the mail; it doesn’t run the company.
For officers and decision-makers, the more useful filings are the annual reports or statements of information that most states require. Those periodic filings list officers, directors, and sometimes managing members with their addresses. Skip them and the state can suspend or administratively dissolve the entity, which is why most businesses keep them current. Secretary of state databases are usually free to search online by entity name or filing number.
Why the Owner Still May Not Show Up
Public business filings have a real blind spot: they don’t always name the actual owners. An LLC’s articles of organization might list only a manager or organizer, not the members who hold equity. The document that spells out who owns what percentage is the operating agreement, and the operating agreement is private. Unless you’re a party to a lawsuit or a transaction that forces disclosure, you won’t see it.
The Corporate Transparency Act was supposed to narrow this gap by requiring most small businesses to report their beneficial owners to the Financial Crimes Enforcement Network. The requirement has since been pulled back sharply. As of March 2025, all entities formed in the United States are exempt from beneficial ownership reporting. Only foreign entities registered to do business in a U.S. state or tribal jurisdiction must file.6FinCEN.gov. FinCEN Removes Beneficial Ownership Reporting Requirements for US Companies and US Persons Even for those foreign entities, the database is not open to the public. Access is limited to federal law enforcement, state and local law enforcement with a court order, certain financial institutions, and Treasury personnel.7Financial Crimes Enforcement Network. Fact Sheet: Beneficial Ownership Information Access and Safeguards Final Rule For the foreseeable future, tracing the real humans behind a domestic LLC or corporation still takes either private disclosure or a legal proceeding.
Domain Names
Every registered domain has an ownership record kept by the registrar that sold it, under rules set by the Internet Corporation for Assigned Names and Numbers.8ICANN. What Does ICANN Do? Registrars must collect the registrant’s name, street address, city, country, phone number, and email at registration.9ICANN. Registration Data Policy
For years, anyone could pull that information through the WHOIS protocol. That changed after the European Union’s General Data Protection Regulation took effect in 2018. ICANN’s Registration Data Policy now allows registrars to redact personal data fields, including the registrant’s name, address, phone number, and email, when required by applicable privacy law or when the registrar has a commercially reasonable purpose.9ICANN. Registration Data Policy Most registrars now redact by default for individual holders. A lookup will show the registrar, the creation and expiration dates, and name server information. The owner’s identity will often read “REDACTED.”
As of January 2025, ICANN retired the legacy WHOIS service for generic top-level domains and replaced it with the Registration Data Access Protocol. RDAP returns the same data in a standardized format with better security, international character support, and the ability to grant different levels of access to different requesters.10ICANN. ICANN Update: Launching RDAP, Sunsetting WHOIS ICANN’s own tool at lookup.icann.org queries RDAP first and falls back to WHOIS for older extensions that haven’t fully transitioned.11ICANN. Registration Data Lookup Tool
Even with personal data hidden, the registrar must still keep accurate records on the back end. Under the Registrar Accreditation Agreement, registrars verify registrant contact details at registration, re-verify them periodically, and investigate reported inaccuracies.12ICANN. 2013 Registrar Accreditation Agreement If you need to reach a domain’s owner for a legal matter or a purchase inquiry, many registrars offer a contact form or masked forwarding email that delivers your message without exposing the registrant.
Trademarks, Patents, and Copyrights
Intellectual property ownership lives in federal databases, and unlike vehicle records or beneficial ownership filings, these are wide open.
Trademarks
The United States Patent and Trademark Office maintains a searchable database of every registered and pending trademark. You can search by the mark, the registration number, or the owner’s name through the Trademark Electronic Search System.13United States Patent and Trademark Office. Search Our Trademark Database Results show the registrant’s name and address, the goods or services the mark covers, the filing date, and the current status.
Patents
Patent records are available through the USPTO’s Patent Public Search tool, searchable by number, inventor, assignee, or keywords in the patent text.14United States Patent and Trademark Office. Patent Public Search One trap: the inventor named on a patent is often not the current owner. Companies routinely acquire patent rights from employees and other inventors. To find who owns a patent today, check the USPTO’s Assignment Center, which tracks every recorded transfer for both patents and trademarks.15United States Patent and Trademark Office. Assignment Center
Copyrights
Copyright ownership is harder because registration is voluntary. A copyright exists the moment a work is fixed in a tangible form, so many copyrighted works never appear in any public database. For registered works, the U.S. Copyright Office runs a Public Records Portal covering registrations from 1978 forward, with digitized records back to 1898.16U.S. Copyright Office. Copyright Public Records Portal You can search by title, author, claimant, or registration number. When copyrights change hands, the new owner can record the transfer with the Copyright Office, which serves as public notice of the change, but only if the underlying work was registered.17Office of the Law Revision Counsel. 17 USC 205 – Recordation of Transfers and Other Documents If a work was never registered, there may be no public record of who owns it.
Liens on Business and Personal Property: UCC Filings
For personal property and business assets like equipment, inventory, or accounts receivable, financial claims are tracked through Uniform Commercial Code filings. When a lender makes a loan secured by a business’s assets, it files a UCC-1 financing statement with the secretary of state (or, for certain real-property-related filings, with the county). That filing puts the world on notice that the lender has a security interest in the specified collateral. Most states let you search UCC filings online by debtor name, and results show the secured party, the original filing date, and a description of the collateral.
A UCC search is most useful during due diligence. If you’re buying a business or a piece of expensive equipment, a lien search tells you whether someone else already has a financial claim on those assets. A UCC filing doesn’t mean the debtor doesn’t own the property. It means a creditor has a recorded right to seize it if the loan goes unpaid. When the debt is satisfied, the secured party files a termination statement to release the lien.
