Our Thailand private investigators are experts at gathering evidence and delivering it back to our clients in real time. We are practiced in covert surveillance and rely on techniques which are used by law enforcement agencies across the world. Most of our agents are former police or military personnel and well equipped with the skills needed to provide a discreet surveillance service. We believe that experience makes all the difference with private investigators, and that our agency’s combined experience allows us to offer a service which is second to none.

Please be assured that all contact with our agency is strictly private & confidential. The need for confidentiality when contacting a private detective is all too obvious - we take your privacy very seriously and have taken steps to fortify any data that is held by us.

Please be assured that if you need to investigate your husband, wife, girlfriend, or boyfriend, that whatever your story or situation, we have likely handled many very similar cases in the past. We believe that our role is to search for the truth and deliver it back to our clients, we are in no way judgemental, and in order to protect your privacy we limit information which is shared with our field agents to details which are needed in order for us to conduct the investigation in each case.

In many cases, where our client may be disappointed to discover their partner is cheating on them, they usually feel that it was better to find out. Most, if not all of our clients, would never have confirmed suspicions about their partners had they not decided to contact us and start an investigation. In many cases infidelity investigations can lead our clients to save vast amounts of money which they would have otherwise spent during the course of a relationship.

Of course, if you partner is not being unfaithful, then we can help to confirm this and deliver peace of mind.

4worldlovers: We are a friendly family owned and operated private investigations company which provides services including finding people such as lost family and friends, various kinds of research in Thailand, and discreet surveillance such as of Thai wives and foreign husbands with the results being videos, photos, analysis, reporting, and counseling (such as for trying to save a family). We do other work, too, but only ethical good guys work. We appreciate that many solutions should stay private.

Our main office is in Bangkok but we cover most of Thailand. For example, Pattaya, Phuket, and Isaan operations are common, but we have gone to most provinces since we became publicly visible with this private investigation website in 2002. (Work of the Director here goes back to the 1990s.) During the virus pandemic in 2020-2023, we travel by car, not airplane, and we are very safe. Our Managing Director is a physicist who takes this issue seriously, and our agents are smart and diligent.

We are a longtime registered, incorporated Thailand small company of private investigators and analysts in an economical and modest office, and low profile. We are mainly extended family and close friends who we trust, are well trained, retained a long time, experienced, work together well as a team, and reliable. The two Directors of our company are a husband and wife team -- American and Thai -- Mark and Kanta ("Na"). Agents have been recruited from Na's extended family, plus some long time work acquaintances and friends.

We accept a diversity of jobs of various sizes, from short and economical to considerably longer assignments. Most of us are Thais with diverse skills and experience at practically all levels of society, which is important to be effective in Thailand, discreet, and cost efficient. Alternatively, we offer a western expat private investigator working and living in Thailand since 1994 with extensive experience in mainstream Thai culture as well as tourist areas and business sectors, and good Thai language skills (and additional languages), who is Managing Director.

Our staff are mainly researchers and surveillance agents to watch and follow people discreetly. Mark and Na are not just desk directors, they are often in the field. (Mark originally came to Thailand from Washington, D.C., in 1994, due to an Asia Regional Office being located in Bangkok, and eventually decided to stay in self-employment.)

We are sensitive that our work in many cases will affect peoples lives quite significantly -- both the client's and the subject's -- so we are careful to do the right thing, and diligent to do our best. We carefully choose which cases are acceptable (no overly selfish or ill intent). We are sensitive to privacy as private investigators. Key traits of our private investigators are understanding, nonjudgemental, minimal bias, objectivity and positive attitude. We understand a wide variety of people (both Thai and foreign) and their origins, options in life, and outlooks, without arrogantly judging. We find out facts for you to base your own decisions. We often don't judge for a client, though are quite willing to offer extensive analysis and advice, based on the many years of experience in Thailand of our investigation operation. (Of course, scams and some other very bad things we do judge.)

Thus, we basically find out "The Truth" and more facts, and offer analysis based on an intimate understanding of Thailand and broad, in-depth experience, without pre-judging or prejudice, and can offer advice if you wish. However, we are not overbearing in judgment and advice in many cases and situations (depending on what we find out).

” In other words, do you have doubts? It’s ok, many of us have. Have you noticed curious behavior lately that you don’t quite understand?
