Many people assume a private investigator can simply “pull” CCTV or booking data on demand. In reality:
We’ve had cases where:
These results come from experience, preparation and a bit of luck. They are possible, but never guaranteed.
For in‑person site visits in Bangkok, Pattaya or Phuket, fees start from 11,500 THB including tax. Prices rise for after‑hours work, complex cover stories or multiple locations. You’ll always get a clear quote first.
One quick visit isn’t always enough. In bigger cases we can book an agent into the hotel overnight. That lets us:
This can beat a short site visit, but it still carries no guarantee. If you want the strongest proof, real‑time surveillance is best.
Gathering evidence after the fact is harder. Whenever possible, instruct us before the suspected meeting. Our teams can follow the subject discreetly and record video or stills, making later hotel enquiries far more productive.
No. We can make the request, but the decision is up to the property. Your fee pays for our effort and time - not a promised outcome.
Recordings are normally recycled after 7 to 30 days. The sooner we act, the better the chance the footage still exists.
Remote requests rarely work. Face‑to‑face contact gives us a far better chance of persuading staff.
Full name of the subject, dates of stay, hotel name, room number if known, booking emails, receipts or any photos.
We’ll still document everything. You’ll get a report showing who we spoke to, what was said, and our advice on next steps.
Yes. Catching someone in real time gives stronger evidence and often makes hotel staff more willing to cooperate later.
If you accept the uncertainty involved and still want to proceed, contact Bangkok Investigators for a private consultation.
If you're looking to verify whether someone owns land (or property) in Thailand, you will need to physically visit or send someone to visit the local Department of Lands Office for the specific area concerned. Property deeds and ownership records in Thailand are kept exclusively in paper format at the local, sub-provincial level, and digital databases do not exist for ownership verification.
The process for accessing property deeds can vary significantly depending on your specific local land office. Each land office may have its own set of requirements based on the case or reason for your inquiry, such as verification for legal purposes or personal checks. To get accurate details on what is required, including necessary documentation like the Chanote number, you should directly contact the land office involved.
A background check can reveal addresses linked to an individual, but those addresses alone do not confirm ownership. As explained above, property and land ownership records are stored in paper format at local land offices. To check for property ownership across the entire country, you would need to visit every provincial land office and manually go through their records. Since there are thousands of land offices, this is clearly not a practical option.
Thailand offers a useful online resource: LandsMaps.DOL.go.th. Here, you can find information like GPS coordinates, land size, and boundary markers by entering the Chanote number. However, this site does not provide ownership details, as those are only available offline at the relevant land office.
Thailand does not have a centralised national land registry in the way some other countries do. Ownership records, including current and historical data from the Chanote (land title deed), are stored locally at individual land offices and are only accessible in person. While online tools like LandsMaps.DOL.go.th allow you to check boundary lines, coordinates, and land sizes, they do not display current ownership or transfer history. That kind of information remains entirely offline and decentralised.
Foreign nationals are largely restricted from owning land in Thailand, with only rare exceptions. As a workaround, some individuals have historically set up Thai companies as holding entities to retain control over land or property. While this practice has come under greater scrutiny in recent years, it remains a notable method in certain situations. The key advantage from an investigative standpoint is that Thai company registration records are digitised. This means that if the person in question is, or has been, listed as a director of a Thai company, those records can be identified through a digital directorship search. This approach can reveal ties to property holdings when direct land ownership cannot be easily established.
Finding specific addresses in Thailand using Google Maps can be challenging. Street numbers often do not match accurately, and villages or less-populated streets might be difficult to locate on the map. GPS coordinates or a registered Google business listing greatly simplify locating a property. In practice, locating an address often involves physically checking street signs, house number sequences, or interviewing locals directly.
A thorough background check can cover a range of details, including marriage and divorce history, family connections, employment history, criminal history, and online presence checks (such as dating sites and social media). However, it cannot include all land/property owned by the individual within Thailand, as this information is not stored in a central database.

If you're dealing with Thai identity documents such as Thai ID cards, passports, or driving licences, verifying their authenticity is critical. Fake Thai ID cards can present major risks, particularly for employers, business owners, or individuals entering personal relationships. In this guide, you'll learn practical ways to check if a Thai ID card is genuine, understand the structure of the 13-digit Thai identification number, and discover when professional verification is needed.
Verifying a Thai identity card's authenticity is essential for several reasons:
Can you check if a Thai person is married by looking at their ID card?
The answer is no. For men, Thai ID cards always show the title "Mr." For women, the title can be "Mrs." if they specifically apply to change it after marriage. However, many married Thai women still carry the title "Miss" on their ID cards because either they don't realise they can update it or choose not to. Thus, the ID alone doesn't reliably show marital status.
If you're involved with someone who turns out to be married, their partner could sue you under Thai law for interfering in their marriage. To avoid this scenario, a thorough background check is highly recommended.
Every genuine Thai ID card features a unique 13-digit personal identification number. These digits represent specific information:
You can easily validate a Thai ID number online using a checksum validator. The checksum (digit 11) verifies that the number sequence follows a legitimate mathematical pattern.

If the ID fails this checksum test, it's definitely fake. However, even if it passes, this does not guarantee authenticity because scammers might use legitimate numbers belonging to others (these are easy to find online), or digitally alter an ID which features a genuine ID number.
Common forms of fake Thai ID cards include:
Subtle digital manipulations or professional counterfeit documents can often evade basic visual inspections or online validators.
Although online checksum validation helps identify obviously fake IDs, it’s important to recognise its limitations:
For situations where authenticity is critical, such as employment, serious relationships, or important business deals, it's best to hire professional verification services. At Bangkok Investigators, we provide:
Many fake Thai ID cards we've uncovered passed basic checksum validators online. Digital manipulation and sophisticated forgery methods mean that initial checks are often insufficient for total confidence.
To protect yourself fully from fraudulent identities, consider hiring a private investigator specialising in Thai ID verification and thorough background checks.

Authenticating Thai identification documents involves more than basic online checks. Professional verification is essential if you need to be certain of someone's identity and background. By taking these extra steps, you minimise risks in employment, business, and personal relationships and ensure decisions are based on accurate, verified information.
If you're trying to verify someone's education records in Thailand — whether they are currently attending university, completed a course, or have claimed qualifications — there are important things to understand about how education records are handled in the country.
While background checks do not typically include surveillance, it is possible to add what we call a lifestyle check — a discreet surveillance service which helps to understand someone's real-world movements, daily habits, and whether their lifestyle aligns with what they claim. This can be especially useful if you're unsure about their university attendance or general honesty. Our surveillance fee depends on the location of the case. If you'd like a quote, please let us know exactly where the work would take place.
