Investigating someone using public records means using government databases, court filings, and official agency records to verify identity, confirm background, and surface any adverse history — without paying for unreliable third-party reports.
Quick Answer: Work through official government sources in this order: county property records to confirm address, state and federal court records to check litigation and criminal history, Secretary of State records to verify business interests, and licensing databases to confirm credentials. Cross-check every significant finding across at least two independent government sources. Commercial people-search tools are optional — useful for generating additional leads, but not a substitute for official records.
This guide is for: verifying someone before a business transaction, checking a contractor’s background before hiring, confirming identity before meeting someone in person, due diligence before a financial commitment, researching your own public record, or fraud prevention and identity verification.
⚠️ Legal Notice: Public records research is legal. Using findings to make formal employment, housing, or credit decisions requires FCRA compliance and written consent from the subject. This guide covers personal research, due diligence, and identity verification only. It does not constitute legal advice.
Before You Start: Define the Objective
A focused investigation produces better results than an unfocused one. Before opening a single database, write down the specific question you’re trying to answer:
- Is this person who they say they are?
- Do they have a litigation or criminal history?
- Is this business legitimately registered and in good standing?
- Does this person live where they claim?
- Are there liens, judgments, or financial red flags in the public record?
The answer determines which record systems matter — and when you’re done.
What to Collect Before Searching
Every identifier you already have becomes a potential entry point into a different record system. Collect everything before opening a database:
Identity identifiers:
- Full legal name
- Known name variations (maiden name, nicknames, name changes)
- Approximate age or date of birth
Location identifiers:
- City and state
- Any known prior addresses
Contact and professional identifiers:
- Employer name
- Phone number or email address
- Any business name associated with the person
The more identifiers you start with, the faster and more targeted the search. A unique name plus a city produces far cleaner results than a common name alone.
The Right Search Order
Start with official government sources. Use commercial aggregators only to fill gaps.
Government records — courts, property databases, licensing boards, business registrations — are the authoritative layer. They are created and maintained by official agencies for legal purposes, and they are independently verifiable. Commercial people-search tools are faster but compile and aggregate data from other sources, introducing their own lag, gaps, and errors.
Use this order:
- Property records → confirm address (government)
- Court records → litigation and criminal history (government)
- Criminal records → dedicated criminal databases (government)
- Business and licensing records → verify claims (government)
- Liens and financial records → financial red flags (government)
- (Optional) Aggregators → identify additional leads only
- (Optional) Digital check → corroboration only
- Cross-check everything → verify independence of sources
Step 1 — Confirm Address Through Property Records
The county property assessor or recorder is one of the most reliable public sources for confirming address and property ownership. These are government records maintained by county agencies — not compiled from third-party data.
How to search:
- Google:
[county name] property assessor search - Search by name to find properties owned by the subject
- Note property address and mailing address — these sometimes differ
What property records reveal:
- ✔ Current address and mailing address
- ✔ Property ownership history and purchase dates
- ✔ Co-owners or joint ownership
- ✔ Tax records linked to the property
- ✔ Transfer history — who sold to whom and when
An address confirmed in a county property record is significantly more reliable than one appearing only in a commercial aggregator profile.
⚠️ Availability varies: Not all counties have fully online records. Rural counties and older records may require a direct call to the county office.

Step 2 — Search Court Records
Court records are the most important public record source for background research. They surface criminal history, civil lawsuits, judgments, bankruptcies, and restraining orders — information that appears nowhere in any commercial profile.
State Court Records
Every state has an online court portal. Search the subject’s full name in every state where they have lived or worked. A person with history in three states has three separate sets of state court records.
Find your state’s court portal:
- Google:
[state name] court records online search - Browse by state: How to Check Court Records
What to look for:
- ✔ Criminal cases
- ✔ Civil lawsuits and judgments
- ✔ Small claims
- ✔ Restraining and protective orders
- ✔ Family court records
⚠️ Searching one state is not complete. Records follow state jurisdictions. Search every state where the subject has lived or worked.
Federal Court Records — PACER
PACER covers all federal district, bankruptcy, and appellate courts nationwide. Registration is free; document access costs approximately $0.10 per page, but a basic name search typically costs under a dollar.
What to search for in PACER:
- ✔ Federal criminal cases
- ✔ Civil rights and fraud litigation
- ✔ Bankruptcy filings — contain sworn schedules of all assets, all debts, employment history, and recent financial transactions. Among the most detailed public documents available.
- ✔ Federal regulatory enforcement actions
⚠️ Digital access gaps: Many court portals have electronic records only from the mid-1990s or early 2000s. Older records may exist only in physical court archives.
→ Step-by-step guide: How to Check Court Records
Step 3 — Check Criminal History
Criminal records are maintained at the state level. There is no single national database accessible to the public. A thorough criminal check requires searching multiple systems.
| Source | What it covers | Cost |
|---|---|---|
| State Dept. of Public Safety / BCI | State criminal history | Free (most states) |
| State court portal (Step 2) | Criminal cases by name | Free |
| PACER (Step 2) | Federal criminal cases | ~$0.10/page |
| nsopw.gov | Sex offender registry — all 50 states | Free |
To find your state’s criminal records search: Google: [state] criminal records public search
nsopw.gov searches all 50 state sex offender registries simultaneously. Free, no registration required.
⚠️ Expunged and sealed records do not appear in public searches. “No criminal records found” means no records found in the systems you searched — not that no criminal history exists.
→ Step-by-step guide: How to Find Criminal Records
Step 4 — Verify Business and Professional Claims
If the person claims to own a business or hold professional credentials, verify both through public records.
Business registration: Every state maintains a Secretary of State business entity database. Search the business name and the person’s name as a registered agent, officer, or member.
- Google:
[state] Secretary of State business search - Most are free and searchable by name
What to confirm:
- ✔ Whether the business is legitimately registered
- ✔ When it was formed and by whom
- ✔ Whether it is in good standing or has been dissolved
- ✔ Who the registered officers and agents are
Professional licenses: Doctors, lawyers, contractors, financial advisors, nurses, and dozens of other licensed professions maintain public records through state licensing boards.
- Google:
[state] [profession] license verification - Example:
Texas contractor license lookup
What licensing records show:
- ✔ Whether the license is active
- ✔ When it was issued and when it expires
- ✔ Any disciplinary actions or complaints filed
→ Step-by-step guide: How to Verify a Business Is Legitimate
Step 5 — Search for Liens and Financial Records
Liens are public records that signal financial problems — unpaid taxes, unpaid judgments, and unpaid contractors all result in filings recorded in county or state records.
County Recorder / Register of Deeds Judgment liens and mechanic’s liens are recorded at the county level where the subject owns property. Search the subject’s name.
IRS Federal Tax Liens Federal tax liens are filed with the county recorder where the subject’s property is located. Public and searchable through the county portal.
UCC Filings Uniform Commercial Code filings show when a lender has a security interest in someone’s business assets. Search the Secretary of State’s UCC database by name or business name.
Optional Step — Use Aggregators to Identify Additional Leads
After completing the government record searches above, commercial people-search tools can help surface additional addresses, phone numbers, or states worth searching that you may have missed.
Free tools:
- TruePeopleSearch.com — free, no login
- FastPeopleSearch.com — free name and phone search
- Whitepages.com — free basic results
Use aggregator results to generate new identifiers — then verify any significant finding against a government source.
⚠️ Aggregator results are leads, not confirmed facts. Three aggregator profiles showing the same address do not verify that address. An address appearing in a county property deed does. Use aggregators to find new things to search — not to confirm what you’ve found.
Optional Step — Run a Digital Check
Public social media profiles can corroborate or contradict what you’ve found in government records — but they are the least reliable layer and should never be the primary source.
What to check:
- LinkedIn — employment claims and professional history
- Facebook, X, Instagram — location, timeline, associates
- Google:
"[full name]" "[city]"— news mentions and public posts - Google Lens or TinEye — reverse image search to check whether a profile photo appears on other accounts
⚠️ Social media is self-reported and unverified. Verify employment claims against Secretary of State filings or court records before treating them as established.
Step 6 — Cross-Check Everything
Before drawing conclusions, compare your results across independent sources.
What “independent” means: Two sources are independent when neither derived the information from the other. A county property deed and a PACER bankruptcy filing listing the same address are independent. Two aggregator profiles showing the same address may share a common origin and are not.
What to cross-check:
- ✔ Does the address from Step 1 match court filings from Step 2?
- ✔ Does the claimed employer appear in a Secretary of State filing?
- ✔ Does the name on the court record match other confirmed identifiers?
- ✔ Are dates consistent across multiple independent records?
- ✔ Do aggregator results agree or conflict with government records?
Conflicts between sources are not problems to dismiss — they are often the most significant findings. An address appearing in an aggregator but not in any property record or court filing warrants further investigation.
Confidence Levels in Public Record Research
Not all findings carry equal weight. Apply this framework to every significant result before drawing conclusions:
Level 1 — Unverified Lead Found in a single commercial aggregator, social media profile, or self-reported source. Has not been confirmed through any government record. Action: Do not act on this. Search for government-source confirmation.
Level 2 — Single Source Confirmation Found in one government database (court filing, property record, licensing board). Reliable but not yet independently corroborated. Action: Treat as a working finding. Search for independent corroboration.
Level 3 — Corroborated Confirmed across two or more independent government records that did not derive their data from the same source. The same address appearing in a county deed and a PACER filing is corroborated. Action: This is a confirmed finding. Include in your conclusions.
Level 4 — High Confidence Confirmed across multiple independent government records, consistent with timeline evidence, and free of contradictions in any other source searched. Action: This is your strongest category of finding. Reliable for decision-making.
Best Search Order for Common Situations
You only have a name and city
- County property assessor → confirm address and full name
- State court portal → search by name
- PACER → federal records
- Secretary of State → business interests
- (Optional) Aggregators → additional identifiers
You only have a phone number
- Reverse phone lookup (TruePeopleSearch or Whitepages) → get name and city
- Then follow the name-and-city sequence above
You’re verifying a contractor before hiring
- State contractor licensing board → license status and disciplinary history
- Secretary of State → business registration and standing
- County court portal → civil lawsuits and judgments
- County recorder → lien history on their business address
- PACER → any federal litigation
You’re checking court history across multiple states
- PACER first → covers all federal courts in one search
- Then each state court portal for every state the subject has lived or worked
- Document every state searched, including states that returned nothing
You’re verifying a business owner’s background
- Secretary of State (all relevant states) → confirm role and tenure
- PACER → bankruptcy and federal litigation
- State courts → civil and criminal history
- Licensing boards → professional credentials
- UCC filings → financial obligations on business assets

What to Do With What You Find
Organize findings into three categories before drawing conclusions:
Confirmed findings — verified at Level 3 or Level 4, consistent across independent government sources. Reliable enough to act on.
Leads requiring follow-up — Level 1 or Level 2. Found in aggregators or from a single government source not yet corroborated. Need further verification.
Negative results — systems searched that returned nothing. Document these explicitly. “No criminal records found in Texas, Oklahoma, and Louisiana court portals on [date]” is a meaningful finding — it means you searched and found nothing, which is different from not having searched.

Common Mistakes to Avoid
Starting with aggregators instead of government sources. They compile data from primary sources and introduce their own errors. Government sources are more accurate for the records that matter most.
Searching only one state. Records follow jurisdictions. Someone who lived in three states has records in three separate state systems.
Treating no results as a clean history. Digital access varies by county, state, and time period. “No results found” and “no adverse history” are not the same statement.
Misattributing records. A court record naming “John Smith” is not evidence about your subject until confirmed through additional corroborating identifiers.
Confusing findings with conclusions. A lawsuit filing is a finding. What it means requires judgment. Keep those separate.
Frequently Asked Questions
Can you legally look up someone’s criminal record? Yes — state criminal history databases, court portals, and PACER are all publicly accessible for personal research. FCRA restrictions apply only when findings are used for formal employment, housing, or credit decisions, which require a licensed Consumer Reporting Agency and written consent.
How can you find out where someone lives using public records? The most reliable method is county property records — search the subject’s name in the county assessor or recorder. Court filings also frequently contain current addresses. Aggregator tools can suggest jurisdictions to search but require government-source verification.
How do you run a free background check using public records? Search these free sources: your state’s court portal, PACER for federal records, the county assessor for property and address, nsopw.gov for sex offender registry, and the Secretary of State for business interests. These cover the core record types that paid services compile — accessed directly from official sources at no cost.
What is the best public records search method? Official-source-first. Start with government records — courts, property, licensing, business registrations. These are the authoritative layer. Use commercial aggregators only to identify additional leads, then verify those leads against government records before including them in any conclusion.
Are public records more reliable than BeenVerified or Spokeo? For court records, property records, and licensing information specifically — yes. Paid services compile aggregated data that introduces lag, coverage gaps, and accuracy issues. Government portals are the primary source those services derive their data from. Going directly to the source is more accurate and more complete.
Can you search public records for free? Yes. County assessors, state court portals, PACER (free to search), Secretary of State databases, nsopw.gov, and most licensing boards are all free to access. The core government records needed for a thorough background check cost nothing or near nothing to access.
How do you look up someone legally without their knowledge? Any public record that is accessible without authentication or bypassing any access control is legal to search. This includes court filings, property records, business registrations, and licensing records. You do not need the subject’s knowledge or consent for personal research using official government records.
What records are not available through public search? Sealed, expunged, or juvenile records are not publicly accessible. Records predating digital access may exist only in physical court archives. Private transactions, personal communications, and financial account details are not public records.
