Former employees
Staff who left the client or the other side. Old payroll details are the start; professional profiles and company filings usually show where they went.
OSINT Witness Location Services for Litigation
Witness location services find the people a case depends on: the former employee who saw the documents, the driver who stopped at the scene, the manager who signed the contract and moved abroad. We work only on instructions from counsel, report only to counsel, and leave every approach to the witness to the legal team.
- Instructed by counsel only
- Former employees, eyewitnesses, custodians
- Verified address and contact route
- We never contact witnesses
Short answer
Witness location services find fact witnesses, former employees and records custodians whose details are missing or out of date. OSINT-S traces them from public records, professional profiles and licensed data, verifies identity and reports a current address or contact route to counsel. Counsel decides whether and how to approach the witness under the professional conduct rules. Focused traces take from 10 business days.
Why Litigation Teams Need to Find Witnesses Early
Disclosure duties, deposition schedules and trial dates all assume you can reach the people who know the facts.
In US federal court, initial disclosures must give "the name and, if known, the address and telephone number of each individual likely to have discoverable information" that a party may use to support its claims or defenses (FRCP 26(a)(1)(A)(i)). Lists of names without current details are common, and the opposing side's list may be no better. A witness who cannot be found cannot be interviewed, deposed or served with a subpoena.
Timing matters. Memories fade, former employees move on, and people with key evidence may leave the country. Teams that locate witnesses early can decide who to interview, who to subpoena and who is better left alone, before deadlines force the choice.
Witnesses We Locate With OSINT
Most requests fall into a few groups, each with its own starting point and sources.
Eyewitnesses
People named in police, accident or incident reports, often with a single old address or phone number.
Custodians and signatories
People who kept, signed or approved documents, including former officers of dissolved companies.
Third parties to a deal
Brokers, agents and consultants who were present at negotiations and have since moved firms or countries.
Authors of posts and reviews
People whose public posts are evidence, where the account must first be tied to a person.
Social media evidence capture →Claim witnesses for insurers
Witnesses in liability and fraud claims who stopped responding to the insurer or its counsel.

Lawyers' conduct rules govern who may contact a witness and how, and they reach investigators working for the lawyer. So the approach stays with counsel.
Under ABA Model Rule 4.2, a lawyer must not communicate about the subject of the representation with a person the lawyer knows is represented by another lawyer in the matter, unless that lawyer consents or the law or a court order allows it (Rule 4.2). Under Rule 4.3, when dealing with an unrepresented person, a lawyer must not state or imply that the lawyer is disinterested, must correct a misunderstanding of the lawyer's role, and must not give legal advice other than to get a lawyer where interests may conflict (Rule 4.3). Under Rule 5.3, a lawyer is responsible for a nonlawyer assistant's conduct that would breach the rules if the lawyer orders it or, knowing of it, ratifies it (Rule 5.3).
States adopt their own versions, and other countries have different rules. The practical result is the same: an investigator who calls a witness can create problems for the lawyer. We do not contact witnesses, their families or employers, use pretexts, or record anyone. Our report gives counsel what they need to decide whether the witness may be represented and how to make the first approach.
Witness Location Is Not a Personal Search
We locate witnesses only for a live legal matter, on instructions from a lawyer. We do not find people for personal reasons, even if the request is framed as a case.
We confirm the matter, the instructing lawyer and why each witness is needed before we start. We refuse requests from individuals who want to find someone for personal reasons, requests where the "witness" is a former partner or a person protected by a court order, and any request that suggests the aim is to pressure a witness or discourage testimony. If a witness appears to be vulnerable, for example a victim in the underlying events, we flag that to counsel. The wider rules for tracing people are on our people tracing page.
How an OSINT Witness Search Runs
A scoped list of witnesses, a trace for each, and a report to counsel ordered by your deadlines.
- Instructions from counselThe matter, the witness list, what is known about each person and the dates that matter. We confirm the purpose and quote.
- Confirm identityDates of birth, past employers, roles and addresses separate the witness from people with the same name.
- TraceProfessional profiles, company filings, licensing and court records, public social media, archives and licensed data where its terms allow.
- VerifyA location counts only when independent sources agree it is the same person and it is current.
- Report to counselAddress or contact route, current employer where relevant, evidence and confidence level, after senior analyst review.
What Counsel Receives and How Fast
A per-witness report with location, evidence and confidence, from 10 business days, with urgent delivery for trial deadlines.
Each witness gets a short entry: the verified location or contact route, the current employer or role where it bears on the case, the sources, a confidence level and anything counsel should know before an approach, such as signs that the witness may now work for an opposing party. If we cannot find someone, we report what we checked. Focused traces take from 10 business days; multi-country lists take up to about a month. Urgent delivery for a hearing or deposition date costs 50% more, and everything is under NDA.
Firms that use us across matters can see how we work on our law firms page. Related tracing work includes debtor tracing for enforcement and heir and beneficiary tracing for estates. Personal data is processed only for the legal matter (GDPR). Witness location is one of our OSINT services for litigation teams.

Witness Location FAQ
Our firm needs witness location services for five former employees of a client who left over the past six years — can you find them before our initial disclosures are due?
Usually, yes. Send the names, last known addresses, roles, dates of employment and your deadline. Former employees tend to leave clear professional traces, so most can be located within a focused trace, which takes from 10 business days. We report each location with evidence and a confidence level, ordered so the most important witnesses come first.
I'm an associate and the key eyewitness in our car accident case gave the police a phone number that no longer works — can you find her without calling her?
Yes. We work from the police report details, such as her name, age and old address, and trace her through public records, profiles and licensed data. We never call or message witnesses. You receive a verified address or contact route, and your team decides how to approach her consistently with your conduct rules.
Can your investigator just call the witness for us, explain the case and ask whether she would be willing to give a statement to our firm?
No. We locate witnesses; we do not contact them. Professional conduct rules on represented and unrepresented persons, and a lawyer's responsibility for the conduct of assistants, make the first approach a matter for counsel. If your firm uses a separate investigator for interviews, they work under your instructions. Our report gives you what you need to plan that approach.
I'm not a lawyer, but I'm suing my former landlord myself and want to find a former tenant as a witness — will you take my case?
We take witness location cases only on instructions from a lawyer acting in the matter. Without counsel, we cannot confirm the purpose or make sure the approach to the witness follows the rules. Some courts can help self-represented parties with subpoenas and service; a local legal aid service or the court's help desk can explain the options.
Our arbitration has a hearing in three weeks and a key signatory has moved abroad — how quickly can you locate him, and does working in another country change anything?
We can work to that date with urgent delivery, which costs 50% more. Cross-border traces use the records available in each country and take longer than domestic ones, so send everything you have at once. Data protection rules such as the GDPR apply when the witness is in the EU or UK; we limit the work to what the arbitration needs.
