There is no single guide that can tell you if someone is a good girl. Everyone is different, but there are warning signs you can look for in your Thai girlfriend that might suggest she is not the wholesome partner you hope she is. These are some of the common red flags we see in real cases.

If your Thai girlfriend works in a bar or has done in the past, that is a major red flag. Most bar girls we investigate are found to be cheating on their partners. No matter what she says, if she is part of the bar scene the chances of her being faithful are slim. Women in this line of work often become skilled at lying, telling convincing stories while seeing other men. We specialise in cutting through the stories and finding the truth.
A small percentage of Thai women smoke. Outside the adult entertainment scene it is still viewed negatively in many circles. If she smokes regularly, it can be a clue that she is connected to nightlife.
Although views on tattoos are changing, visible ink on Thai women is still often linked to the sex industry. It is uncommon to see visible tattoos in typical office jobs. Tattoos do not prove anything by themselves, but they are worth factoring in with the rest of the picture.

We see many cases where a woman keeps multiple accounts. One account shows her in a relationship with a European boyfriend. Another account shows her with an American partner. Different men, same setup. Often one account is for family and friends, while the other is used to curate a fake romantic life for foreign partners. It is a clear way to hide multiple relationships.
If you are romantically involved with a Thai woman who is legally married, her husband could sue you under Thai law. Social media posts, photos, and private messages can be used as evidence of a relationship.
We can confirm marriage and divorce status, and search for hidden risks by running a background check on your Thai girlfriend. This includes official marital history and family details, and we can use advanced OSINT checks to see if she appears on dating sites or in adult material. Every enquiry is handled privately and confidentially. We provide clear reports and free quotes before any work begins.
Wages in Thailand are lower than in many Western countries, so some financial help can be normal in serious relationships. If she brings up money constantly or always hints at problems, ask yourself if she cares about you or mainly about your wallet.
General claims like all Thai men are bad are a red flag. Many Thai men are loyal and responsible. Strong blanket statements can reveal more about her history and motives than about the reality around her.
Fluent English can come from university study or from years of work with foreigners in nightlife areas. If her English is very good, think about where she learned it. The source can tell you a lot.
Drinking on special occasions is normal. If she is out every weekend or drunk often, she is likely living a nightlife lifestyle. That is not typical for most Thai women with traditional values or steady jobs.
If she does not work but always seems to have money or is out late with friends, be careful. Many women in nightlife survive on gifts and support from multiple boyfriends. Some never ask directly, they wait until the boyfriend offers.
Maybe she is. Skilled scammers know which red flags foreigners watch for, and they avoid them. They visit temples with you, introduce you to family, and avoid asking for money for months to slowly build trust. If you have doubts, the only way to be sure is to verify with a proper background check.
We offer discreet and professional services to help you verify your Thai girlfriend’s background. From background checks and surveillance to decoy work, we have the tools to help you find the truth.

We’ve encountered numerous instances where individuals set up websites falsely claiming to operate legitimate businesses from Thailand. These scammers often present themselves as exporters of in-demand goods such as tyres, used engines, vehicle parts, rubber products, metals, rice, paper, or textiles. After receiving partial payment for a shipment, they disappear with your money. Some invent new excuses to request more funds before vanishing completely.
Once fraud is committed, there’s usually very little that can be done unless proper checks were done beforehand. These individuals often provide fake documents and use mule bank accounts to receive funds, making them difficult to trace. This type of scam is widespread and affects people worldwide trying to import from Thailand.

Scammers frequently claim to be based in Thailand, though they may actually operate from another country. Once you’ve sent funds via bank transfer—whether for tyres, vehicle parts, industrial goods or agricultural products—recovering them is extremely difficult. Verifying that you’re dealing with a legitimate Thai company before making payment is the best way to protect yourself. Even basic due diligence can save you from serious losses.
If you’re planning to buy or import from Thailand, especially in high-risk sectors like automotive, manufacturing or agriculture, here are a few basic checks you can do on your own before paying:
While free checks are useful for spotting obvious scams, professional fraudsters can fool even seasoned buyers. Here's how our services give you stronger protection:

We regularly uncover fake documents like these. Don’t rely on appearance—rely on verification.
Company checks start at 5,000 THB, including a full English report on the company’s registration and financials. For more complex cases, our basic due diligence service starts at 6,000 THB and may vary depending on what's involved. If you’re sending money to a supplier in Thailand, this small fee can save you from a costly scam.
Site visits are quoted separately based on location. Contact us with the company’s full address and we’ll provide a free, no-obligation quote.
We’ve seen fraud in nearly every sector: counterfeit exporters claiming to sell tyres, vehicle parts, rice, paper rolls, steel scrap, latex gloves, seafood, and more. These scams often involve fake proforma invoices and counterfeit company seals. Many sites look professional and use stolen photos from real businesses.
Ask yourself: do you know who you’re really dealing with? We can confirm whether the business is truly registered, if their address is valid, and whether any of their documents have been altered or forged.
Scam exporters often avoid giving full details or use free email addresses. If you ask for company registration documents and only receive a PDF with unclear seals or signatures, that’s a red flag. Ask for the Thai company number and let us confirm it for you.
A proper background check and physical site visit is the best way to confirm if a supplier is real. If they’re asking for upfront payment but refusing to share proper documentation or references, walk away—or call us first.
In the past 12 months, 74% of the companies we investigated turned out to be high-risk or outright scams. Many clients were about to transfer money for orders of tyres, scrap metal, paper or vehicle parts—only to discover the company didn’t exist, or the documents were faked. Our checks saved them from serious financial loss.
Thai scammers can operate across all industries. Some even run multiple scam websites at once. The best way to protect yourself is by verifying everything before payment.
We work with clients around the world to confirm the legitimacy of Thai companies. Whether you’re importing tyres, rice, vehicle parts, or any other product, our investigation services help ensure you're dealing with a real business—not a fake exporter.

Our services often save clients far more than they cost. We confirm if a company is registered, verify documents, visit their offices or warehouses, and report findings clearly in English. We can also check if they operate from a real location or just a rented mailbox.
Our team covers all of Thailand with regional investigators. If you’re unsure about a Thai supplier, get in touch and we’ll recommend the best solution for your case. Quotes are free, and turnaround is quick.
Recent surveys indicate that 56% of the Thai respondents admitted to having affairs while married - this surprising statistic ranks Thailand as one of the most unfaithful nationalities in the world.
As a leading private investigation agency based in Thailand, we decided to compile our own statistics on the subject of infidelity in Thailand. The purpose of gathering this data was to assess how many of our clients discovered that their partner was actively cheating on them whilst we conducted our investigations.
You might find there to be a lack of statistics available on Thai girlfriends or on the subject of infidelity in Thailand involving foreigners and Thai women. Compared with other subjects these topics seem to have a lack of data backed statistics relating to them (this seems to be the case with private investigator statistics across the board). With this in mind we decided to compile our own data based on infidelity related investigations carried out by our agency from the period of January 1st 2019 – January 1st 2020.
In line with our privacy policy and data protection policies, all data that was gathered in order to form these statistics was fully anonymous.
These statistics relate to all cases as a whole which involved Thai girlfriends (or wives) that were suspected of cheating on their partners. It’s important to recognize that our statistics only relate to people that felt the need to engage the services of a detective agency to investigate suspicions of infidelity in their partner. Because of this, our information should not be used to form sweeping opinions relating to certain groups of people as a whole.

These statistics relate to cases which involved Thai bar girls (women working in beer bars), also ladies working in a go-go bars and massage parlors. For our data these service industry type occupations were grouped together. This information suggests, unsurprisingly, that infidelity seems to be more likely where one partner works at an Thai adult entertainment venue.

In cases which involve foreign men and Thai ladies, we often discover that the lady works at a nightlife venue while claiming to have a legitimate job. Many of our clients would never have discovered that their partner was working in the sex industry had they not instructed us to start an investigation.
We recognize that individuals who suspect that their partner might be committing acts of infidelity are likely to seek out information such as this article (and others). We need to make clear that information available on the internet relating to infidelity should only be used as a rough guide, and should not be used to form important life decisions.
Our experienced tells us that there will always be situations where an individual doesn’t match any of the traits, stereotypes or statistics that you might find online but that is engaged in acts of infidelity. There might also be people who are cheating on their partners but that don’t match any of the “warning signs” which you might find on the subject.
Our job is to investigate and find the truth. We will assess your situation and suggest the best way for us to help you. Please include as much information as possible when contacting us so that we are able to understand your circumstances.

When we are preparing to check a Thai girlfriend’s background for our client, we first need to take a look at their partner’s circumstances and lifestyle. Checking your Thai girlfriend can take a number of different paths depending on the information that you are looking to uncover.
As a leading detective agency based in Thailand, our job is to advise our clients on the best way forward in each respective case.
We offer standard and enhanced background checks as well as conventional ‘on the ground’ investigations. The best course of action typically depends on the specific circumstances in any given case.

Background checks are recommended for those that decide to form serious relationships with their Thai girlfriend. If you decide to provide financial support to your partner, or to get married and pay a dowry/sin sod, for example, then running a background check would be especially advisable.

If your Thai girlfriend works at a beer bar, go-go bar, club, massage parlor, or any similar occupation then the best course of action for an investigation would often be our decoy service. As part of our decoy service we can establish whether or not a lady might be leaving the establishment with clients or potentially having inappropriate contact with clients. We can find out if the lady claims to have a boyfriend or whether she might be looking to recruit multiple different boyfriends.
Please be aware that our agents will never engage in sexual activity or contact during our work and that we must obey the law at all times. If you require a quote for our decoy service then please advise us the exact location of your partner’s workplace when getting in touch with us.
We can also conduct personal surveillance in order to check your Thai girlfriend’s lifestyle and see how she acts when you are not around. If you suspect that your partner could be cheating on you then surveillance can often prove to be vital when it comes to finding out for sure and gathering evidence.
We have conducted surveillance on men and women from all different backgrounds and walks of life. We can check your Thai girlfriend by providing surveillance for you no matter your partner’s profession or whether she is unemployed.

“Surveillance” simply means to watch someone, follow them, and document their activities by taking photos/video. After conducting surveillance we will contact our client and explain exactly what happened in a clear and concise report which will include any photos/video that were gathered during the investigation. In other cases we can provide surveillance updates in real time instead.
If you require a quote for surveillance then please remember to include important information and details such as the exact area in Thailand you need us to work, and the type of environment that you require us to provide surveillance in. We will usually need the address (or a building/street name) in order to calculate any travel to the assignment and confirm a quote for surveillance in your case.
Please browse through to the Bangkok Investigators website for more information on Thai lady investigations, or feel free to get in touch with us if you are interested in any of the services described in this article. We offer free, no pressure quotes for all work, and all contact with us is strictly private & confidential.
