I will be your Detective

Trusted by 98,750 clients,
we help solve various challenges, protect your rights, and ensure your peace of mind.

Do you always treat others kindly? When things go wrong, do you start blaming yourself?

When you encounter roadblocks in life, it is like when your car breaks down. You should question whether the uneven road caused the flat tire, or whether unstable parts need replacement. Life is the same — it does not always treat us kindly, and the problem is not with you or me.

Conducting an investigation is like repairing a car — the issue is not visible from the surface. By looking from different angles, and with care and professionalism, you can always find the answer.

During my years as a supervisor in the traditional investigation industry, I saw companies blindly chase sales targets. Everyone was busy dealing with new clients while those already hurt and unable to move forward were handled carelessly. As technology and legal provisions evolved, there was no time left for study and training. I saw how outdated thinking kept both clients and practitioners from moving forward.

No one can move forward if, after their wounds are laid bare, they are treated merely like parts to be replaced.

By blending a mechanic’s craftsmanship with experience in the investigation field, we refine our services and treat every trusting client with care.

We maintain structured training programs so every colleague keeps pace with the times.

The birth of Zitong lets us race together toward a better road ahead.

Walk with Zitong, clearing the path for you.

Private Investigation Agency FAQ

A "徵信社" in Taiwan is a legally recognized private investigation agency operating within the country's legal framework. It serves a similar function to what is referred to internationally as a Private Investigator. Our mission is to help individuals or businesses solve complex issues that are difficult to handle through normal channels—especially private matters that cannot be investigated publicly by the police or courts.

Common services include gathering evidence of infidelity, locating missing persons, investigating romance scams, surveillance, asset verification, corporate risk investigations, employee background checks, handling abusive partners, reconciliation, divorce planning, and even assisting with family disputes or personal crises. We bring professional experience and customized solutions tailored to each real-life case.

Due to the legal constraints in Taiwan, all qualified agencies are registered under names like "徵信社" or "investigation company" and are subject to supervision by the Ministry of the Interior, local courts, lawyers, or police authorities. We not only provide professional services but also emphasize legality, confidentiality, and ethical boundaries. We are the dark knights guarding our clients' rights from the shadows.

The range of services a detective agency can provide depends on its resources and capabilities. At Zitong Investigation Agency, we often say, “If you can imagine it, we can do it.” Our services include: evidence collection for extramarital affairs, catching and confronting cheaters, reconciliation after infidelity, business investigations, relationship restoration or sabotage, correcting problematic children, persuading third parties to leave, locating missing persons, bad debt recovery, proxy services, venting sessions, and more.

At Zitong Investigation Agency, we not only follow legal regulations, but also implement strict personnel selection criteria and privacy protection mechanisms:

  1. Each client is served one-on-one by a dedicated case manager, who is the only person aware of the client’s identity and purpose.
  2. The case manager signs a confidentiality agreement with the client.
  3. Field agents also sign confidentiality agreements for each case.
  4. Case managers refer to investigators using case numbers or aliases only.
  5. The company tracks progress but never accesses client details.

Legal detective agencies do not charge a flat rate, nor do they make up arbitrary prices. At Zitong Investigation, we evaluate every case carefully before quoting a fee—this includes factors such as the amount of information provided, target profile, operating area and time, and the complexity of the mission. We do not use vague language or hidden charges. Every cost is clearly explained and transparent, protecting clients from traps like low entry prices followed by high-pressure upcharges.

Depending on the nature of the case and terms of the contract, investigations can take less than a day to as long as 2–3 months or more. On average, most cases take about one month.

The process varies depending on the case. It generally involves setting operational guidelines, gathering intelligence and evidence, strategic planning, ongoing analysis and adjustment, and ultimately delivering a final report to the client.

In most agencies, the case manager leads the case, and every agency has top-performing case managers and field agents. Here are a few suggestions:

  1. Clearly define case completion standards in the contract to avoid disputes.
  2. Before signing, ask if regular updates can be provided.
  3. Check whether the case manager thoroughly understands your situation.

Based on past experiences and industry risk management, we do not accept fully anonymous inquiries due to risks such as harassment from competitors or undercover operations by law enforcement using false identities. We also do not provide case advice without verifying basic identity information.

However, rest assured that all client information is kept under the strictest confidentiality. Once we confirm your basic identity, we’ll sign a mutual confidentiality agreement. Internally, all data is managed through case numbers and aliases. Even before signing a contract, all your conversations and records will be protected.

We understand your concerns, which is why we’ve established a careful balance between safety and privacy—allowing you to express your needs without fear of exposure or misuse.

Thanks to technological advances and professional training from seasoned investigators, our operations are highly discreet. Compared to traditional methods, Zitong Investigation Agency operates with up-to-date tools and techniques. The chances of being discovered are extremely low. Even if exposure occurs, clients need not worry—we have standard operating procedures (SOPs) for every situation to ensure your safety and anonymity are never compromised.

All field investigations include video documentation and attendance logs. These materials are provided to the client for confirmation upon case closure.
