If you require the services of a private investigator on Koh Samui, then we can help. Our agency has been successfully completing assignments on Koh Samui for over 20 years.

Koh Samui, also known as Samui Island, lies in the Gulf of Thailand and is a Thailand’s second largest island. The island is known as a popular destination for tourists with many hotels, bars, clubs, and entertainment catering to foreign visitors. Often is the case that foreign visitors will be suspected of engaging in acts of infidelity at some of the numerous different adult entertainment venues on the island.

If you suspect that your partner might be cheating on you, we can help to check if this is the case and gather evidence (photos/video). Our experienced and local agents are able to help with a wide range of different issues, however we aim to focus on infidelity (cheating husband/wife) investigations on Koh Samui.

Please feel free to contact us for a free, no obligation quote.

Local experience and knowledge

We believe that local knowledge and experience makes all the difference when conducting investigations in Thailand, and this could not be more true when it comes to monitoring and surveilling people on Koh Samui. Whereas other companies have been known to send surveillance teams to the island from Bangkok or other areas of Thailand, our agents are already based on Koh Samui and in most cases have resided on the island for decades.

If you suspect that your partner might be cheating on you in Koh Samui then we can help to gather evidence of their infidelity in the form of photos/videos. Our aim is to remain in the shadows and gather images of your partner’s activity without them ever being aware that an investigator is watching them.

Please feel free to contact one of our experienced team members for a free quote. Please mention to us that you require our services on Koh Samui when getting in touch with us and we will do our best to help.

Hiring a private investigator

We recognise that many of our clients may not have hired detective agencies before. We aim to respond to all queries as swiftly as possible and will be on hand to answer any questions that you might have before, during and after the duration of your case.

We believe that communication is key and will aim to be in regular contact with you whilst conducting surveillance on your behalf, keeping you up to date with our progress as we complete each day of surveillance for you. We are able to provide you with live updates so that you know exactly what is going on at all stages in the investigation. Once we have collected satisfactory evidence for you then you may choose to discontinue surveillance.

The amount of time needed to gather high quality images showing infidelity can vary massively from case to case… Often is the case that our clients will continue until they have collected numerous photos and documented their partner’s infidelity over the course of several days. Whatever the case, we will aim to work with you and do our best to conclude the investigation to your satisfaction.

For further information information

If you require further information on our services and how we might be able to help you then please feel free to get in touch with us. Please note that we will usually require all details related to the assignment, such as locations where the subject resides and is likely to frequent, details about any vehicles used by the subject (or their preferred mode of transportation), photos of the subject, and any other details which could help us (for example, description/photos of any clothes that are worn by them, hotel room numbers, etc).

As a general rule, the more information that is provided to use the better; however we will endeavour to work with whatever information is available to us in each respective case. We offer free, no pressure quotes for all work. Please feel free to get in touch with us and see how we are able to help in your case.

If you suspect your husband or partner is cheating on you during his trip to Thailand, you’re not alone. As a seasoned detective agency, we have caught hundreds of foreign men engaging in infidelity in Thailand, time and time again. We’ve worked on cases involving men from all walks of life—young, old, married for decades or just a few months—and the patterns we’ve uncovered are shockingly similar.

Thailand, with its infamous nightlife and sex industry, is a notorious hotspot for men seeking extramarital affairs. With over 150,000 sex workers estimated to be working in the country, according to UNAIDS, the temptation is all too real for many. Based on our investigations, the number of men who cheat during their visits to Thailand is staggeringly high, and the consequences for their relationships back home are often devastating.

Our Experience: Hundreds of Cheating Husbands Caught

Our detectives have worked on hundreds of infidelity cases in Thailand, and the sad reality is that foreign men engaging with sex workers here is incredibly common. Men travel from their home countries to Thailand under the guise of “business trips” or “holidays in the sun,” but many have ulterior motives. The bars, go-go clubs, and massage parlours of cities like Pattaya, Bangkok, and Phuket are filled with foreign men seeking sexual services. We’ve caught men ranging from their twenties to their eighties—no age group or type of relationship is immune.

Through surveillance, we’ve captured undeniable evidence of infidelity: men spending time with prostitutes, ladyboys, and even multiple partners during the same trip. These men rarely match a single stereotype—some are white-collar professionals, others are retirees, and many are family men. But one thing unites them: they believe they can get away with it. With alcohol, nightlife, and a sense of anonymity on their side, many feel emboldened to indulge in risky behaviours they would never consider back home.

Where Do Men Pay for Sex in Thailand?

Most men engaging in infidelity while in Thailand do so in obvious venues like beer bars, go-go clubs, or massage parlours. According to UNAIDS, Thailand's sex industry is widespread, contributing to over 3 million visits to sex workers annually. While men might claim they’re “just having a beer” or “playing golf,” the reality is that many of these bars are staffed with prostitutes. The “bar fine” system—where a customer pays a fee to take a bar girl out for the night—is incredibly common.

Beyond the bars, nightclubs are another hotspot for infidelity, where ‘freelancers’—prostitutes who operate independently—often approach foreign men. Our detectives have seen cases where men hire sex workers under the cover of nightlife, believing they won’t be caught because they’re far from home. In reality, we often find these men soliciting prostitutes night after night during their stay.

The Dangers of Sexual Tourism

In addition to the emotional toll infidelity takes on relationships, there are serious health risks associated with sex tourism in Thailand. Thailand has one of the highest rates of HIV in Asia, with female sex workers facing an HIV prevalence of up to 20% in some areas, including Bangkok, according to AIDS Data Hub. STIs, such as the antibiotic-resistant “super gonorrhoea,” have also been rising, fueled by unprotected encounters with sex workers, as reported by the NYPost. The risks of contracting and spreading diseases through sexual tourism are higher than many people realise, especially when foreign men demand unprotected services from sex workers.

Psychological Reasons: Why Men Cheat in Thailand

Men who cheat on their wives or girlfriends in Thailand don’t always fit the profile of habitual cheaters. Often, they are lured by the sense of freedom and anonymity they feel thousands of miles from home. We’ve seen numerous cases where men, once they arrive in Thailand, give in to the temptations presented by the country’s sex industry. It’s not uncommon for men who visit in groups to indulge in what they see as a “harmless” activity, promising each other they’ll keep their indiscretions secret.

Some men may also convince themselves that what happens in Thailand won’t affect their relationships back home. Unfortunately, this couldn’t be further from the truth. The psychological toll of betrayal, combined with the risk of STIs, often leaves lasting scars on relationships, even after the man returns home.

How We Can Help

If you suspect that your husband or boyfriend is cheating on you while in Thailand, we can help. With decades of experience in private investigations across Pattaya, Bangkok, Phuket, and Chiang Mai, our team specialises in discreet surveillance. We provide clients with high-quality evidence, including photos and videos, that leave no room for doubt. We understand that the truth can be painful, but many of our clients find solace in finally knowing what’s really going on.

Prepare for the Truth

Before starting an investigation, it’s crucial to consider how you will handle the results. Many women who learn the truth from our reports are shocked at the extent of their partner’s betrayal. We’ve uncovered affairs involving much younger women, ladyboys, and multiple sex workers during the same trip. If you’re prepared to face the truth and need closure, we’re here to help you every step of the way. For more information, please contact us for a confidential consultation.

As a leading detective agency based in Thailand, we regularly run Thai girlfriend background checks for our clients. We offer basic and enhanced background checks depending on the needs and requirements of our clients. Thai girlfriend background checks typically include:

• Check marital status and marital history
• Name of any previous husbands and divorces information (where applicable)
• Property residence checks (check for children or boyfriends living at the subject’s property)
• Education/employment checks
• Social media checks
• Dating/adult website checks 
• Criminal record check/check for arrest warrants

Note: We will NOT hack your partner’s phone or social media accounts as this is against the law, please don’t ask. All background checks are completed by us with 100% confidentiality and discretion. The subject will never find out that they have been subject to a background check. We offer free quotes for all work. Please feel free to get in touch with one of our experienced team members for more information on our background checks service.

Background check alternatives

Background investigations are useful to check if a Thai girl is married, check her marital history, living circumstances, work history, etcetera. However, running a background check on your Thai girlfriend is not always the best form of investigation, depending on your circumstances and the type of information that you are looking to uncover.

If your girlfriend is working at a bar then you might find our decoy service to be more appropriate – as part of our decoy service we can find out if your girlfriend is leaving the bar with customers and whether she tells customers that she has a boyfriend, for example. Decoys can also be used at massage parlors, go-go bars, and many other service industry type occupations.

If you suspect that your Thai girlfriend might be actively involved in another relationship that she is concealing from you then we can investigate through personal surveillance instead, which involves checking the subject’s whereabouts and collecting hard evidence in the form of images/video to show her activity.

Are Thai girlfriends faithful?

We think it’s fair to say that the majority of Thai women are faithful to their partners and do not tend to commit acts of infidelity… However, it’s important to realize that the majority of women in Thailand also cannot speak English fluently and do not form romantic relationships with foreign men. Thai ladies that seek relationships with foreigners are effectively a small subset of the population. There is undoubtably another subset of women in Thailand that are responsible for proliferating romance scams, where their sole aim of a relationship is to extract money from their partners. Traditionally women that are responsible for romance scams tend to have occupations in the nightlife scene, such as bar girls, go-go dancers and ladies working in massage parlors. However, over the past several years we have seen a steep increase in more refined Thai women that seek to manipulate their partners by having multiple foreign boyfriends at the same time. We have seen, for example, many Thai women that were attending universities meet their boyfriends through dating apps or websites. As these women are perceived to be more respectable than ‘working girls’, they often find it easier to form serious romantic relationships with foreigners; who in turn have a false sense of security that their girlfriend really is ‘different’. University students and Thai women that are working “normal jobs” have the potential to work this scam much easier than women you might find in the nightlife industry. All ladies are different and it’s very difficult to predict whether or not your partner is likely to be faithful based on advice or information found online. If you have read the horror stories and are having suspicions about your Thai girlfriend, we can investigate her and uncover the truth in your case.

Why do Thai women cheat on their partners?

If we’re discussing relationships between Thai ladies and foreigners, then we think it’s fair to say that the main motivation for infidelity in these relationships tends to be money. It is not secret that some unscrupulous Thai ladies make a living out of being in relationships with foreigners… The goal for many of these women is to have several boyfriends at the same time – some men might send the lady an allowance every month while others only help out if the lady is having financial problems. Women that have been exposed to the nightlife scene for prolonged periods tend to develop a strange morality where they no longer feel guilt for cheating on their partners. We have seen many ladies that appear to enjoy working as escorts and spending time with new men. If your girlfriend is living in a city such as Bangkok, Pattaya or Phuket, then it’s easy for her to try and hookup with men at bars and nightclubs which encourage freelancers to drink there. We have seen many women that work respectable jobs in the daytime head out in the evenings to such places. For many ladies this is a lifestyle that they really seem to enjoy.

Check your Thai girlfriend

We recognize that taking the decision to check your Thai girlfriend can be difficult. Our goal is to help provide you with peace of mind and the confidence to proceed with significant life decisions. If we are not able to give you peace of mind then we will have the unfortunate task of delivering the truth in your situation and evidence of infidelity. It often makes sense to perform these checks before you begin the costly process of applying for a spousal visa for your partner or as pre-marital checks before committing yourself into a serious relationship. Our goal is always to analyze our client’s situation and offer the best and most cost-effective solution in each case.

Accepting the results

For many of our clients taking the step to hire us proved to be a very wise decision which allowed them to save vast sums of money and heartache in the long run. It’s important to prepare for the results of your investigation, to consider all potential outcomes and how you might react to them. Whilst we always try to offer our clients the support and advice, for some people the truth can be a hard pill to swallow, especially if the investigation leads us to taking photos/videos of their partner with other men. Thailand, Thai women, and Thai culture are all very different to the Western world. Due to the prevalence of romance scams it usually makes sense to run a Thai girlfriend background check when you’re getting to know a Thai woman, no matter how you met each other or the stage of your relationship. Please feel free to contact us and see what we can do to help in your case.

Does your Thai girlfriend have multiple Facebook profiles? If so, this could be a cause for concern, especially if she's involved in romance scams. Our team at Pattaya Private Investigators (PPI) frequently handles cases involving social media infidelity, and multiple profiles can be a red flag.

Why Do Thai Women Have Multiple Facebook Pages?

Many Thai women involved in romance scams maintain multiple Facebook profiles. A common tactic for scammers is to juggle multiple boyfriends, often from different countries, while appearing "in a relationship" with each one on different accounts. This is a tactic used by bar girls and women in the Thai entertainment industry, but it can also apply to women in seemingly respectable jobs. A study by AARP found that romance scams are the most common type of online fraud, costing victims $304 million in 2020.

Scammers often create multiple Facebook profiles to maintain relationships with several men at once, customising each account to cater to different audiences. This allows them to hide existing relationships from potential new partners while maintaining the illusion of exclusivity. As social media becomes more intertwined with daily life, it's important to recognise the warning signs of deception.

Finding Her Hidden Facebook Accounts

Uncovering hidden social media accounts isn't easy. Women involved in romance scams often block their primary boyfriend's account from viewing these secret profiles, making it almost impossible to find them by searching normally. Even with hours of searching, you are unlikely to discover them on your own.

At PPI, we specialise in social media background checks and open-source intelligence (OSINT) investigations. We use advanced techniques to uncover hidden digital footprints, often discovering multiple secret profiles tied to the same individual. However, it is important to note that while we’ve successfully found secret Facebook accounts in the past, we cannot guarantee a 100% success rate due to the complexity of these scams.

The Thai Girl Romance Scam

Romance scams in Thailand often involve Thai women managing multiple online relationships. Men often show off their new Thai girlfriend on social media, filling their profiles with photos and setting their relationship status to "in a relationship." This can create a psychological effect that strengthens the man’s emotional bond with his girlfriend, making him more likely to send money or gifts.

In reality, many of these women maintain several profiles, each showing them "in a relationship" with different men, all while continuing to date or receive financial support from multiple foreign boyfriends. The goal for the scammer is to accumulate as many boyfriends—and as much financial support—as possible. In some cases, we’ve seen women receiving money from as many as 4 or 5 boyfriends at the same time, using the funds to buy homes, cars, or even luxury items.

Protect Yourself from the Thai Girlfriend Scam

If you suspect your Thai girlfriend is scamming you, it’s important to act quickly. At PPI, we offer a range of investigative services designed to uncover the truth. We provide background checks to verify your partner's claims, personal surveillance to monitor her activities, and even decoy services to test her loyalty.

Our background checks include social media investigations, which can reveal hidden profiles, dating accounts, and any suspicious online activity. We’ve seen social media used as a tool in many cases of infidelity, and we use our expertise in OSINT to track down digital evidence.
