Private Investigation Services in China | Infidelity, People Search and Corporate Investigations - TPI 遠大徵信社

When a China-related matter involves suspected infidelity, a missing person, an unclear business operation, concerns about a potential partner, or a commercial dispute, the first step is to define the specific question that needs to be answered. We assess each case according to its legitimate purpose, available information, location, intended use of the findings, and applicable local requirements.

China Mainland Compliance Notice

All investigation assignments involving Mainland China are assessed individually according to the purpose of the engagement, the location, the information involved, and applicable local laws and requirements. We only undertake matters with a legitimate purpose and do not provide services involving unlawful access to protected information, unauthorized tracking or monitoring devices, intrusion into non-public premises, hacking, illegal acquisition of personal data, or the collection or transfer of information that is restricted by law or involves state secrets or national security.

Where personal information, sensitive information, or cross-border data is involved, the lawful scope of collection, processing, use, retention, and delivery is assessed separately according to the circumstances of the case.

Infidelity investigations, people searches, relationship background checks, corporate investigations, commercial fact-finding, and evidence-related support may all involve different legal and practical considerations. The appropriate scope depends on the purpose of the matter, the information already lawfully available, and the specific facts that need to be verified.

Below is an overview of the China-related investigation matters we commonly assess and the information that may be useful at the initial consultation stage.

1. Infidelity Investigations in China

When a spouse works, lives, or travels frequently in China and there are concerns about a specific relationship, unexplained changes, reduced contact, or a possible second household, we can assess the factual issues that may need to be verified and whether an appropriate investigation is feasible.

Common factual questions

Whether available information supports or contradicts a stated work, travel, or leave arrangement.
Whether a spouse and a particular person appear together in specific events or circumstances relevant to the matter.
Whether lawfully obtained information indicates a continuing relationship, shared accommodation, or another fact relevant to the client’s legal or personal objective.
Whether photographs, messages, public information, dates, and other lawful evidence can be cross-checked.
Whether the information presently available is sufficient to distinguish confirmed facts from suspicion or assumption.

Useful information to provide

Recent photographs lawfully held by the client.
Known city, company, workplace, or other basic identifying information.
Specific dates, trips, events, or other time-sensitive facts relevant to the matter.
The suspected person’s name, photograph, or publicly available information, if already known.
Messages, photographs, public posts, or other information the client lawfully possesses.

Our findings reflect what can actually be verified. If the available facts do not support the client’s original suspicion, the findings will state that clearly.

2. Specific Activity and Fact Verification

Some clients refer to this type of request as activity monitoring or movement investigation. In practice, we do not treat those expressions as authorization for unlimited or continuous observation of a person’s daily life.

The appropriate scope must instead be tied to a legitimate purpose, a defined time period, and specific facts that are reasonably necessary to the matter.

Examples of specific factual questions

Whether a particular event occurred on a relevant date.
Whether information already provided by a subject is materially inconsistent with lawful evidence.
Whether two people or organizations are connected in a particular event or transaction.
Whether a known business or public location is connected to the matter.
Whether several lawfully obtained records can be organized into a reliable event timeline.

We do not undertake open-ended assignments whose objective is simply to build a complete record of a person’s daily movements, routine, private life, or unrelated contacts.

3. People Search and Contact-Lead Verification

People-search matters may involve a lost family member, a former business contact, legal service of documents, an unresolved commercial matter, or someone who has been out of contact for a significant period. The lawful scope depends heavily on the legitimate reason for locating the person.

We may assist with confirming

Whether the person’s identity appears consistent with the information provided.
Publicly available employment, company, professional, or business information.
Whether a previously known contact or address supplied by the client remains relevant to the matter, where lawful to verify.
Possible city-level or contact leads derived from lawful information sources.
Public information relevant to legal service, commercial disputes, or other legitimate purposes.

Information that may help

Full name, former name, English name, or other known identity information.
Photograph, approximate age, former city of residence, or other lawfully known identifying information.
Previous employer, school, telephone number, or public social-media account already known to the client.
Date and circumstances of the last contact.
The legitimate reason for locating the person.

Some clients refer to these matters as “address verification.” We do not obtain protected residential information through hacking, illegal databases, impersonation, unauthorized access, or other unlawful or non-public channels.

We do not accept people-search assignments intended for harassment, retaliation, violence, unlawful debt collection, coercive control, or a purpose the client refuses to explain.

4. Premarital and Relationship Background Checks

Before marriage, cohabitation, a major investment, or another long-term commitment, a client may wish to verify whether important claims made by a partner are consistent with lawful and publicly available information.

Common areas of verification

Whether the person’s name, age, photographs, and public identity information are consistent.
Whether employment, position, and business status are accurately represented.
Whether the person publicly owns, manages, or invests in companies.
Public litigation, enforcement, disqualification, or major commercial disputes.
Material inconsistencies between information presented by the person and lawfully available records.

The purpose of a premarital or relationship background check is to verify specific information that has already been presented or identified as materially important. It is not intended to create an unrestricted profile of another person’s private life.

5. Corporate Investigations in China

A company registration record alone does not necessarily show whether a business is genuinely operating. Before investing, placing an order, signing a distribution agreement, extending credit, or entering a partnership, additional lawful verification may be useful.

Depending on the case, we may verify

Company registration, shareholders, legal representatives, and investment relationships.
Whether a registered business location is consistent with lawfully verifiable operating information.
Whether a claimed factory, warehouse, retail location, or production site appears to exist.
Whether publicly observable or otherwise lawfully verifiable operating conditions are consistent with material business claims.
Whether website and marketing claims appear consistent with verifiable information.
Public litigation, enforcement, abnormal-operation status, or administrative penalties.
Lawfully verifiable relationships between related companies and relevant individuals.

Registration records and operating-status verification should be considered together. Registration alone does not prove active operations, while the existence of premises does not by itself establish production capacity, financial strength, or regulatory compliance.

6. Factory and Operating-Status Verification

When a supplier claims to own or operate a factory, production line, warehouse, or substantial workforce, we may assess whether available lawful evidence and verifiable operating conditions are broadly consistent with those representations.

Common points of verification

Whether the stated factory or business location exists.
Whether signage and publicly verifiable business information are consistent with the stated company.
Whether operating conditions that can lawfully be verified appear consistent with material claims.
Whether the premises appear to be shared with other companies.
Whether there is an obvious discrepancy between claimed operations and the information that can lawfully be confirmed.

Any operating-status verification reflects conditions and information available at the time of verification. Exact production capacity, financial strength, product quality, environmental compliance, labor compliance, or technical capability may require qualified audits, inspections, laboratory testing, legal due diligence, or other specialist work.

7. Pre-Investment and Business-Partner Investigations

When a proposed transaction involves a substantial payment, unusual payment terms, unfamiliar counterparties, or complex ownership, appropriate due diligence can reduce avoidable risk before money is transferred or contracts are signed.

Common objectives

Confirming whether the counterparty appears genuinely operational rather than merely registered.
Verifying legal representatives, shareholders, related companies, and relevant contact persons through lawful sources.
Reviewing major public litigation, enforcement, disqualification, and transaction disputes.
Checking lawfully verifiable information relating to offices, warehouses, factories, or retail locations.
Verifying claimed agency, distribution, or brand-authorization relationships where appropriate.
Comparing material business representations with lawful and verifiable facts.

Business investigations are generally most useful before payment, investment, or contract signing. After a dispute has arisen, the relevant questions may shift toward responsible entities, publicly identifiable assets, actual business operations, documentary evidence, and legal recovery options.

8. Trademark Infringement and Unfair Competition Evidence

When counterfeit goods, unauthorized trademark use, copied packaging, false company names, or suspicious distribution channels are identified, the first step is to define the specific infringement-related facts that need to be established.

Depending on counsel’s requirements, we may assist with

Confirming where suspected infringing goods are publicly offered or sold.
Documenting publicly accessible shops, exhibitions, or other relevant business locations where lawful.
Verifying operators, company names, and public contact information.
Checking whether online promotion and offline business information appear connected.
Documenting lawfully observable products, packaging, pricing, channels, and dates.
Supporting lawful sample purchases or transaction documentation where appropriate and under counsel’s guidance.

Trademark, copyright, patent, and unfair-competition matters have different legal requirements. It is often more effective for counsel to define the facts that need to be established before evidence-related work begins.

9. Insurance and Claim-Related Fact Verification

Where an insurer, company, or lawyer has a documented and legitimate concern about a specific claim, we may assess whether particular facts can lawfully be verified.

Possible areas of inquiry

Whether specific publicly verifiable facts appear materially inconsistent with a claim.
Whether public corporate, employment, or business information is relevant to the issue under review.
Whether dates, entities, records, or other lawful information connected with an incident can be cross-checked.
Whether documentary and publicly available information contain material inconsistencies.

We do not undertake prolonged or unrestricted observation of a person’s private life merely because a claim exists. Any work in this area must relate to a specific legitimate concern and remain within applicable privacy, personal-information, insurance, and local legal requirements.

10. What We Deliver

Deliverables depend on the type of case, the information lawfully available, and the agreed scope. They may include:

Event timeline: Relevant facts organized by date and event where appropriate.
Identity findings: Individuals or entities identified and the lawful basis for the identification.
Relevant location information: Known or lawfully verified business, public, or case-related locations where necessary.
Photographs or video: Where lawfully obtained and appropriate to the agreed matter.
Public-record findings: Company, litigation, enforcement, administrative, or other verifiable information.
Findings summary: A clear distinction between confirmed facts, unresolved points, client-provided information, and insufficient evidence.

We do not present assumptions as facts or shape findings to match a client’s original suspicion. If the available evidence does not support the concern being investigated, the report will state that clearly.

What We Do Not Provide

Every assignment must have a legitimate purpose and remain within applicable privacy, personal-information, data-protection, and local legal boundaries.

Hacking or unauthorized access to phones, computers, email, or social-media accounts.
Illegal acquisition of household registration, communications, banking, medical, accommodation, location, tracking, or other protected non-public personal data.
Unauthorized or unlawful installation of tracking, listening, recording, or monitoring devices.
Unauthorized entry into homes, hotel rooms, private offices, or other non-public spaces.
Impersonation, forged documents, violence, threats, harassment, entrapment, retaliation, or other unlawful conduct.
People searches intended for harassment, coercive control, unlawful debt collection, revenge, or another illegitimate purpose.
Collection, acquisition, possession, transfer, or disclosure of information restricted by law or involving state secrets or national security.

Our approach is adjusted according to the legitimate purpose of the assignment, the information lawfully available, the jurisdiction involved, and the legal requirements applicable to the specific matter.

How a China Investigation Begins

Explain the issue: Tell us what has happened and the specific fact or problem you need to clarify.
Provide information you already lawfully possess: This may include names, photographs, city, company information, important dates, public records, or other relevant lawful evidence.
Legitimate-purpose and feasibility assessment: We review the purpose of the matter, the jurisdiction involved, the nature of the information, and whether there is an appropriate lawful starting point.
Define the factual scope: The persons or entities involved, relevant dates, specific questions, information sources, and expected deliverables are identified in advance.
Fee proposal: Pricing is based on the agreed scope, expected workload, complexity, necessary lawful resources, and any pre-agreed third-party or case expenses.
Case verification: Agreed factual questions are addressed only through methods and information sources that are considered lawful and appropriate for the relevant location and circumstances.
Reporting: Findings are organized so that confirmed facts, client-provided information, unresolved issues, and supporting material can be clearly distinguished.

The service name alone does not determine whether a case can be accepted. The legitimate purpose, available lawful information, jurisdiction, and specific factual questions must be clear before an effective and appropriate investigation can be planned.
