Private Investigator in Bangkok — A Resident Team That Knows the City
Bangkok is where we work every day. A resident team that knows the districts, routes and traffic rhythms plans observation more precisely and starts faster than anywhere else. We cover all Bangkok districts and the surrounding provinces of Nonthaburi, Pathum Thani and Samut Prakan.
Assignments we handle most in Bangkok
- Infidelity and behaviour observation in business and residential districts
- Background checks on employees, partners and counterparties based in Bangkok
- Locating the current address of a debtor or a person a lawyer needs to serve
- Confirming that a company registered at an office address actually operates
- Verifying people met online who say they live or work in Bangkok
Areas we cover daily
Sukhumvit, Silom, Sathorn, Ratchada, Lat Phrao, Ramkhamhaeng, Bang Na, the Thonburi side and the surrounding provinces. Work around gated condominiums and housing estates is done from public areas only, and rush-hour traffic is built into the plan from the start.
How fast can you start?
Research-based verification starts as soon as the assignment is agreed. Most field assignments in Bangkok can be staffed within 1–2 working days; ask about urgent cases. You can meet us in Bangkok to discuss details or brief us on WhatsApp from anywhere.
Outside Bangkok and nationwide
We take assignments in every province, with travel and accommodation itemised in the quote. Cases where the subject moves between Bangkok and the provinces are planned as one continuous assignment.

Frequently asked questions
Do you only cover Bangkok?
No, we work nationwide, but Bangkok and its suburbs start fastest because the team is resident.
The subject lives in a guarded condominium. Can you still work?
Yes, by observing from public areas around the building and its access routes. We never enter private premises.
Can we meet in person?
Yes, in Bangkok at a place convenient for you, or we can start on WhatsApp or a video call right away.
Are the suburbs priced like Bangkok?
Generally yes. Some outer areas carry a small travel charge, which is stated in the quote.
