India’s Trusted Detective Agency Since 2014
For more than two decades, First Indian Detective Agency has been recognised among the leading private detective agencies in India for both personal and corporate investigations. Our team includes former professionals from technology, security agencies, commerce and services industries who bring deep practical experience to every assignment.
Thousands of completed cases covering pre‑matrimonial, post‑matrimonial, loyalty, corporate fraud, asset tracing and missing persons.
Recognised as one of the notable private detective agencies in India in multiple industry listings and media features.
Strong emphasis on lawful, ethical and court‑compatible investigation methods for long‑term client safety.
Our Investigation Process
Every case starts with a confidential discussion where we listen to your situation, expectations, and concerns without judgement. Based on this, we assess the feasibility of the assignment, suggest practical options, and share an estimated time frame and budget so you know exactly what to expect. Once you approve the plan, we begin the field investigation and surveillance, using a mix of human intelligence, discreet enquiries, and technology.
During the active phase of the case, you receive periodic updates through secure channels so that you stay informed but not stressed. Our investigators focus on collecting solid evidence—photos, videos, documents, location details, and meeting logs—rather than gossip or assumptions. After completing the assignment, we prepare a clear, structured report that summarises the findings, attaches key proofs, and, where relevant, outlines potential next steps you may discuss with your lawyer, counsellor, or family. We do not sell or reuse your data, and every case file is handled under strict internal access controls.
Client Confidentiality & Legal Compliance
Confidentiality is at the centre of everything we do. Your name, contact details, and case history are shared only with the minimum number of investigators required to work on the assignment, and all team members are bound by strict internal NDAs. Reports are stored in secure systems, shared only through approved channels, and can be password‑protected on request.
We operate within the legal framework of India and do not accept any assignment that requires hacking, illegal call‑recording, unauthorised access to government databases, or other unlawful activities. Our methods focus on open‑source intelligence, human intelligence, field enquiries, and evidence that can stand up to practical scrutiny. This approach protects both clients and our agency, and ensures that the information you receive can be used safely in personal decisions or legal strategy.

FAQs – Detective Agency in Delhi
Clients usually have many practical questions before they start an investigation, and we encourage them to ask openly. One of the most common questions is how charges are decided—our fees depend on the complexity of the case, the number of days of surveillance, the locations involved, and the size of the field team needed. Another frequent doubt is how long a report will take; simple verifications can finish in a few days, while complex, multi‑city fraud or matrimonial cases may require several weeks for accurate results.
People also ask whether we really work across India; the answer is yes, but we plan each out‑station case carefully to ensure that travel, stay, and local resources are used efficiently. Finally, almost every client wants to know if their identity will remain confidential. We reassure them that their details are never shared with the subject of the investigation and that our internal systems are designed so only authorised team members can access any case file.
