INTERNATIONAL INFIDELITY & ACTIVITY INVESTIGATIONS
PHILIPPINES / THAILAND / VIETNAM
Overseas business trips, overseas postings, long-term stays.
Precisely because you are far apart, there are things you want to know.
Do you feel that what your spouse or partner living overseas tells you does not match their actual situation? Unusual business trip schedules, times when they cannot be reached, relationships formed locally—there are many reasons for concern.
At TSK INTERNATIONAL, we accept consultations on overseas infidelity and activity investigations, focusing on the Philippines as well as Thailand, Vietnam and other countries.
Rather than drawing conclusions from speculation alone, we organize the dates, times and places you want to verify, and consider whether an investigation in line with local laws is possible.
Consult About Overseas Infidelity & Activity Investigations
WHEN SOMETHING DOES NOT ADD UP
Having doubts about someone's activities overseas does not, in itself, mean it can be concluded that infidelity or adultery has taken place. It is important first to organize the specific events that raised your doubts and what you want to confirm objectively.
Business trips to the Philippines or Thailand have increased, and their behavior has changed since returning home. We organize the specific points to confirm, such as who they are meeting at their destination and whether they are acting according to their schedule.
During a long-term solo posting, there are more days and hours when they cannot be reached. We consider ways to compare their explanations of their life there with facts that can be verified.
They seem to be close to a particular person overseas, but you do not know the actual relationship. Based on the purpose of the investigation and the lawful scope of verification, we consider matters such as their contact with others.
There are discrepancies between their explanation, such as a business trip, sightseeing or a trip with friends, and the schedule they share or publicly available information. We distinguish facts from speculation as we organize the information.
Objective materials about their activities overseas are needed to decide on the future of the marriage. We consider the types of evidence required, taking into account consultation with a lawyer.
There are points you want to confirm about the life and activities overseas that your partner or spouse has described to you. We clarify the scope necessary for a legitimate purpose.

PHILIPPINES INVESTIGATION FOCUS
Overseas business trips, solo postings, long-term stays. We focus on consultations about activities in the Philippines.
Metro Manila is a hub of business activity, and some Japanese nationals stay there on business trips or postings. At the same time, the Philippines is a large country that includes many islands, and transportation conditions and travel requirements differ by region.
Methods and necessary preparations also vary depending on the location to be investigated, such as Manila, Makati, BGC or Cebu.
Based on information you already have, such as the planned business trip schedule and the area where the person says they are staying, we consider what can be verified within the lawful scope.
We begin by organizing why the activities appear suspicious and narrowing down the matters that need objective corroboration.
We organize places of stay, destinations and changes in schedule, and consider whether an investigation is feasible in light of urban transportation conditions and locations where verification is possible.
Consultations are expected not only about business trips but also about sightseeing and long-term stays. We confirm the target area, schedule and travel conditions.
For regional cities on Luzon and other island areas, we assess feasibility on a case-by-case basis.
INVESTIGATIONS ACROSS SOUTHEAST ASIA
We also accept consultations on infidelity and activity investigations related to overseas business trips, postings and long-term stays in Southeast Asian countries other than the Philippines. Investigation methods and legal restrictions differ by country.
This is for consultations where you have doubts about activities on the ground, such as during an overseas business trip or long-term posting in Bangkok, or a stay combined with sightseeing.
We identify the target areas and travel plans, such as Bangkok, Pattaya and Chiang Mai, and consider whether lawful means of verification exist.
You may consult us about verifying activities related to overseas postings, long-term business trips and daily life in places such as Ho Chi Minh City and Hanoi.
We organize the dates, areas and purpose you want to verify, confirm local laws and personal information protection requirements, and then consider whether an investigation is feasible.
We also accept consultations on other countries. Whether an investigation is possible, how it can be carried out, and restrictions on filming and obtaining information differ by country and region.
WHAT CAN BE CHECKED
In an investigation, it is important to narrow down the purpose. Rather than trying to grasp every activity, we organize the necessary points to confirm and consider whether there is information that can be lawfully obtained locally.
TRAVEL ITINERARY
We organize itineraries that the client lawfully holds and schedules shared by the person concerned, and identify the dates and areas that need to be verified.
LAWFUL FIELD OBSERVATION
Only where it complies with local laws and facility rules, we consider verifying and recording activities to the extent necessary.
CONTACT PATTERNS
Where contact with a person relevant to the purpose of the investigation can be confirmed lawfully, we organize the date, time, circumstances and continuity of that contact.
OPEN SOURCE REVIEW
We cross-check publicly available social media information and similar sources against existing materials. We do not gain unauthorized access to private accounts.
PHOTO & VIDEO
Only where filming is permitted and under the applicable conditions, we consider recording the circumstances necessary for the purpose of the investigation. In some cases, filming may not be possible.
INVESTIGATION REPORT
We distinguish between what has been confirmed and what has not, organize the dates, locations and the basis for each piece of information, and report the investigation results to you.
We cannot accept requests that presuppose unlawful investigative methods, such as unauthorized entry into hotel rooms or private spaces, wiretapping of communications, unauthorized login to accounts, or unauthorized location tracking.
EVIDENCE & FACT VERIFICATION
Suspecting infidelity and being able to prove legally recognized adultery are two separate matters. What information gathered overseas actually means must be sorted out according to the purpose of the verification.
The fact that someone had a meal with a particular person or was at the same place does not by itself establish that adultery took place.
It is necessary to organize facts such as dates, locations, circumstances of contact and continuity, and to carefully consider what can reasonably be concluded from that information.
We organize information chronologically so that it is clear when, where and what was confirmed.
Rather than isolating a single scene, we take the surrounding circumstances into account and distinguish facts from conjecture.
Outside Japan, local laws and rules on filming and the acquisition of personal information apply, so confirming legality is essential.
Whether information can be used for divorce, claims for compensation and similar purposes depends on jurisdiction and individual circumstances. Please consult a lawyer as needed.
※We do not guarantee that photographs or activity records can be obtained, or that any materials obtained will be accepted as evidence in court.
OVERSEAS INVESTIGATION GUIDE
When considering an overseas infidelity investigation, having your information organized in advance can sometimes reduce unnecessary work. Please first check the following points.
Arrange in chronological order the number and length of overseas business trips, the days when the person could not be reached, and events where explanations did not match. Please distinguish conjecture from established facts.
Based on the schedule shared by the person concerned and materials that you lawfully hold, organize details such as the country, city and period.
Do you want to know whether the explanation of the trip is accurate, or to verify contact with a specific person? The investigation method differs depending on the purpose.
We help you clarify the purpose of your consultation, such as wanting to repair the marital relationship, wanting to confirm the facts before talking, or considering legal action.
FEES & INVESTIGATION PROCESS
The cost of an overseas investigation varies depending on the target country, the area of stay, the number of days of verification, the investigation method and other factors. By narrowing down your purpose in advance, we clarify the necessary scope of the investigation.
