Bear Witness Private Investigators serves Brisbane and the rest of San Mateo County. Brisbane is a city of about 4,700 people in San Mateo County. We are a California-licensed (PI #18755), veteran-owned firm, and we keep our caseload small so Brisbane clients get direct access to the investigator doing the work.

Courts and Legal Context for Brisbane Cases
Brisbane sits roughly 14 miles from Redwood City, the San Mateo County seat, where the main Superior Court of California, County of San Mateo facilities are located.
Most family law and civil matters for Brisbane go through the Superior Court of California, County of San Mateo. Our reports are written the way attorneys there need them — specific dates, times, locations, and observations, with photo and video that can be authenticated — so the work is usable if the case is contested.
For process serving, proof of service is prepared for filing with the Superior Court of California, County of San Mateo, with the date, time, place, and method of service recorded.
Services for Brisbane Clients
Every service below is handled by a licensed investigator, not passed to a subcontractor.
Infidelity Investigations
When you suspect a partner in Brisbane isn’t being honest, we document where they go, who they meet, and for how long — without judgment, and without your partner knowing. If the answer is that nothing is going on, you’ll hear that plainly — that’s a result too. Nothing about the case is ever shared with anyone outside the firm.
Child Custody Investigations
If you’re worried a custody order isn’t being followed, we can verify it. Our Brisbane custody reports are factual, specific, and ready for your attorney. We can coordinate directly with your family law attorney if you already have one. Our reports describe what was observed, not opinions about the other parent.
Background Checks
Before you sign with a business partner, hire a caregiver, or get serious with someone new in Brisbane, we can verify who they are and what their record shows. If the person has moved or changed names, we trace that history rather than stopping at the first result. Findings are summarized in plain language, with the source of each record noted.
Surveillance
Surveillance is the core of most Brisbane cases. Our investigators stay inside California privacy law — public places only, no trespassing or device tampering — so the evidence stays usable. Reports include a minute-by-minute timeline, so you can see exactly what happened and when.
Process Serving
Standard process servers stop when an address doesn’t work. We locate the subject first, then time service attempts around when they are actually there. Rush service is available when a filing deadline is close. We serve at homes, workplaces, and other locations the subject is known to frequent.
Business Investigations
Attorneys handling Brisbane matters use us for witness location, surveillance, and background research — the investigative work behind a case, done to evidentiary standards. Internal investigations are handled quietly so day-to-day operations aren’t disrupted.
Signs It May Be Time to Call an Investigator
People rarely call an investigator on a whim. These are some of the situations that most often bring Brisbane clients to us:
- Your partner’s schedule changed suddenly and the explanations don’t add up.
- Your attorney needs a witness located or facts documented before a hearing.
- You’ve started a new relationship and something about their story doesn’t fit.
- You’re about to go into business with someone you don’t know well.
What Happens After You Call
- Free consultation. You tell us what you know and what you need confirmed. Everything is confidential.
- A plan and a quote. We outline the approach for your Brisbane case and give you a cost estimate before any billable work begins.
- The investigation. Surveillance, records research, or both, with updates from your investigator as things develop.
- Your report. A written, chronological report with photo and video, plus testimony if your case needs it.
Also Covering the Area Around Brisbane
Cases rarely stay inside one city limit. From Brisbane, our investigators regularly work nearby San Bruno (4 miles), Daly City (5 miles), Millbrae (5 miles), Burlingame (6 miles), Pacifica (7 miles), and Alameda (8 miles).
Before You Hire an Investigator
Start with the license. Every private investigator working in California must be licensed by the Bureau of Security and Investigative Services (BSIS), and you can look up any license on the BSIS website. Bear Witness operates under PI License #18755.
Be wary of anyone who promises results before hearing the details, or who suggests methods like hidden GPS trackers on someone else’s car or accessing private accounts — those can be illegal in California and can sink your case.
Brisbane Investigation FAQs
- How far is Brisbane from the San Mateo County courthouse?
- Brisbane is roughly 14 miles (straight-line) from Redwood City, the San Mateo County seat, where the main Superior Court of California, County of San Mateo facilities are. Some matters are heard at branch courthouses elsewhere in the county; your attorney can confirm the right location.
- Can your evidence be used in the Superior Court of California, County of San Mateo?
- Yes, when it’s gathered legally. We document dates, times, and circumstances so evidence can be authenticated, and our investigators can testify if needed.
- What does an investigation cost?
- It depends on scope. A single evening of surveillance is very different from a multi-week custody case. You get a written estimate after the free consultation, before any billable work.
- What if the investigation finds nothing?
- Then you get an honest report that says so. A clean result still answers the question, and we won’t stretch thin evidence to justify the cost.
- Do you work with San Mateo County attorneys?
- Yes. Family law and litigation attorneys use us for surveillance, background work, process serving, and witness location.
