The approach to searching for a person overseas varies depending on the place where contact was last made, the accuracy of the name and address, the time that has passed, and the systems of the country concerned.

OUR APPROACH
Three Principles We Value in Overseas Investigations
Clarify the purpose of the investigation
What do you want to know, and why do you need to confirm it? Clarifying your purpose makes it easier to organize the investigation that is needed.
Respect each country's laws and rights
Systems governing personal data protection and investigative activities differ from country to country. We confirm not only the necessity of an investigation but also the legality of the methods used to obtain information.
Distinguish what has been verified
It is important not to confuse objectively verified information with speculation or unconfirmed information. Where results have limitations, we make the scope of those limitations clear.
*Depending on restrictions such as the legal systems of the target country, personal data protection, and the documents that can be obtained, we may be unable to accept a request or may limit the scope of the investigation.
