Skip tracing is the licensed-investigator discipline of locating a person who is intentionally or unintentionally hard to find - a judgment debtor avoiding collection, a defendant who must be served, a witness who has moved, a missing heir, an absent parent in a family-law matter, or a person of interest in an investigation. A professional skip trace combines authorized database access, public-records research, behavioral pattern analysis, and lawful field verification to produce a current, verified address (and often a workplace, vehicle, and pattern-of-life summary) that holds up in court. After thirty-plus years of investigative work at National Business Investigations, we have found that 80 to 90 percent of cases attorneys bring to us as “uncollectible” or “unfindable” can in fact be resolved - but only when the trace is run by a licensed professional with access to the right data and the discipline to verify before reporting.

Why DIY skip tracing usually fails

Free internet search, social-media browsing, and the consumer-grade people-finder sites that show up in Google results all draw from stale, scraped, or aggregated data - typically 30 to 36 months behind. They produce a list of possible addresses, no verification, and frequently no indication of which is current. For a civil case, that is the difference between a valid service of process and a default judgment that gets vacated on appeal.

Licensed investigators operate in a different data environment. Under the Fair Credit Reporting Act and the Gramm-Leach-Bliley Act, certain credit-header and financial-affiliation data is restricted to entities with a “permissible purpose” - including investigations conducted for civil litigation, judgment collection, fraud cases, and law enforcement support (FTC, 2024). The Federal Trade Commission enforces these permissible-purpose rules aggressively. Consumer-grade tools cannot legally access this data; licensed PI firms with audited compliance programs can.

What a professional skip trace actually involves

A defensible skip trace is a multi-step investigative process, not a single database lookup. At NBI, a typical workflow includes:

1.         Subject build. The investigator confirms identifiers - full legal name, known aliases, date of birth, last known Social Security Number (last four digits where authorized), past addresses, vehicles, and known associates. Bad inputs produce bad outputs; the build phase is where most amateur traces fall apart.

2.         Authorized database queries. Credit-header data, utility connections, voter registration, motor-vehicle records, court filings, professional license records, and proprietary investigator-only databases are run against the subject build to produce a ranked list of likely current addresses.

3.         Cross-verification. No single source is treated as authoritative. The investigator triangulates two or more independent sources before reporting an address as current.

4.         Field verification when warranted. For service of process, judgment enforcement, or any case where a wrong address creates litigation risk, the investigator (or a licensed local agent) drives the address, confirms residency through observation or pretext-free contact, and documents the verification.

5.         Pattern-of-life summary. Where the case requires it - surveillance to follow, an enforcement action to plan, a contested custody review - the trace expands into a documented pattern: typical work hours, vehicles, frequent locations, and known associates.

A trace that ends at step 2 is the kind of “address” a debt collector buys for $5. A trace that ends at step 5 is what holds up under cross-examination.

When clients call us for a skip trace

The cases that most frequently arrive at NBI fall into a recognizable set of categories. The firm’s approach to locating missing individuals is rooted in this pattern of recurring case types:

•           Judgment enforcement. A creditor or attorney has a valid money judgment and needs to locate the debtor’s current residence, employer, bank, and asset profile to support a writ of execution or wage garnishment.

•           Process service on an evading defendant. A litigant cannot be served because the address on file is stale. The trace produces a current address and supporting documentation that survives a motion to quash service.

•           Missing heirs and beneficiaries. A probate estate or trust cannot close until missing beneficiaries are located and noticed. Skip tracing for probate is a regulated specialty with strict documentation requirements.

•           Family law and contested custody. A parent has relocated without disclosure, or a non-custodial parent has stopped paying support and become unfindable. Family-court judges expect verified locates, not Google guesses.

•           Witness re-location. A material witness has moved between case filing and trial. The trace produces a current address for subpoena service.

•           Workplace investigations and SIU. Employers and insurance carriers retain investigators to locate former employees, claimants, or subjects whose location bears on the claim.

How skip tracing fits into a litigation strategy

Skip tracing is not a standalone product; it is one component of how investigative work supports the litigation timeline. A well-run case sequences the trace at the right moment - early enough to enable service, late enough that the subject information is current at trial. Attorneys who treat the locate as a one-time event in discovery and never refresh it often arrive at deposition or trial with an outdated address and a witness or defendant nowhere to be found.

The Federal Bureau of Investigation reports that scams alone - many of which leave victims chasing relocated subjects - caused more than $16 billion in reported U.S. losses in 2024, and the volume of judgment-collection and fraud-recovery work continues to grow (FBI IC3, 2025). For attorneys, finance teams, and risk officers, a relationship with a licensed skip trace firm is no longer a niche capability - it is part of basic case readiness.

Legal and ethical boundaries professionals work within

A licensed investigator’s value comes precisely from operating inside the rules that DIY operators ignore. NBI investigators do not pretext financial institutions, do not impersonate government officials, do not violate the Telephone Consumer Protection Act in attempted contact, and do not use deceptive practices that would render evidence inadmissible. The trade-offs are explicit: lawful methods are slower than illegal shortcuts, but they produce a result a court will accept.

Frequently asked questions

What is skip tracing?

Skip tracing is the investigative discipline of locating a person who has become hard to find - a debtor, defendant, witness, heir, absent parent, or person of interest. It combines authorized database research, public-records analysis, and lawful field verification to produce a current, verified location and supporting documentation.

Is skip tracing legal?

Yes, when performed by a licensed investigator within the permissible-purpose rules of the Fair Credit Reporting Act, Gramm-Leach-Bliley Act, and applicable state PI licensing law. Federal law restricts certain data sources to permissible-purpose users such as licensed investigators conducting litigation-support, fraud, or judgment-collection work. Consumer-grade “people search” sites are legal but draw from much weaker data.

How long does a skip trace take?

A standard skip trace on a U.S. subject typically delivers a current address within 24 to 72 business hours. Cases involving aliases, deliberate evasion, foreign relocation, or sparse identifiers may take one to three weeks. Field-verified addresses for service of process add one to five business days depending on the local geography.

How much does a professional skip trace cost?

A standard database-and-cross-verified locate typically falls into the $150 to $500 range for U.S. domestic cases, with complex evasion or international cases priced higher. Field verification and pattern-of-life work is billed separately. NBI provides a fixed-scope quote at intake so legal teams can budget the work against case strategy.

What information do you need to start?

At minimum, the subject’s full legal name and last known address. Date of birth, last four of the SSN (where the engaging party has lawful authority to share), known associates, and a recent photograph all improve speed and accuracy. The richer the subject build, the cleaner the result.

Can NBI locate someone outside the United States?

Yes, through vetted partner investigators in most major jurisdictions, with the caveat that data availability and methods differ significantly outside the U.S. International cases are scoped individually and run under the laws of the destination country.

When traditional locates have failed

If you are an attorney, judgment creditor, family-law client, probate fiduciary, or corporate counsel and a critical subject has gone unfindable, contact National Business Investigations to discuss a licensed skip trace. We provide a fixed-scope intake, deliver verified results, and document every step so your locate stands up to scrutiny in court.
