Welcome to CHANAKYA DETECTIVE, India’s Trusted Investigation Agency Since 2003

At present, there is no central or state-level statutory authority in India that regulates or licenses private detective agencies. Since no such regulatory framework exists, there is no concept of a “detective license” issued by the government. Therefore, any claim that a private detective agency is “government licensed” or “authorized by police or ministry” should be viewed with caution, unless supported by written statutory proof.

Then How Do Private Detective Agencies Operate Legally? So Private detective agencies operate like any other professional service business in India, similar to:

IT services
Consulting & advisory firms
Beauty & wellness services
Marketing or research agencies

These businesses do not require a special industry-specific license, but they must be legally incorporated and compliant with applicable laws. Legal Compliance Required for a Private Detective Agency A genuine and lawful private detective agency is required to be: Incorporated or registered under Indian law, such as:

Proprietorship
OPC (One Person Company)
LLP
Private Limited Company
Limited Company

Registered with appropriate authorities, such as:

Registrar of Companies (ROC), (for companies/LLPs)
State Shop & Establishment Act
MSME / Udyam Registration(optional but beneficial)
GST Registration (where applicable)

As an ethical private detective agency of Chandigarh Punjab and India Chanakya Detective Network, We don't deal in any such actives, Which breaches the Indian constitution or any set of Indian Law in any manner like IT Act, telecommunications and data protection and Indian Constitution. India has a very strong Cyber Law and all such actives (like Call Details Records, WhatsApp Details, any illegal hacking) are illegal under IT Act, telecommunications and data protection and Indian Constitution. SO please note the below mentioned points

Indian Constitution

1. It is a criminal offense. It violates the right to privacy under Article 21 of the Constitution (as established in the Supreme Court's Justice K.S. Puttaswamy v. Union of India judgment) and specific laws governing telecommunications and data protection.

Information Technology Act, 2000

2. Section 72: Breach of confidentiality and privacy — If a person with lawful access (e.g., a telecom employee or official) discloses or obtains confidential electronic information without consent, punishment includes imprisonment up to 2 years, or a fine up to ₹1 lakh, or both.

3. Section 72A: Punishment for disclosure of information in breach of lawful contract — Applies to unauthorized disclosure of personal information (including CDR), with imprisonment up to 3 years, or a fine up to ₹5 lakhs, or both.

4. Section 66E: Violation of privacy (capturing, publishing, or transmitting private information without consent) — Punishment: imprisonment up to 3 years, or fine up to ₹2 lakhs, or both.

Indian Telegraph Act, 1885

5. Section 25: Damaging or tampering with telegraph lines/infrastructure to intercept/obstruct communication — Punishment: imprisonment up to 3 years, or fine, or both.

6. Section 26: Applies to telegraph officers who unlawfully intercept or disclose communications — Similar punishment: imprisonment up to 3 years, or fine, or both.

Important Notes

Lawful Access: Only authorized law enforcement agencies (e.g., police with a valid investigation) can obtain CDRs through proper channels, such as under Section 91/92 CrPC (now BNSS equivalents) or Section 5(2) of the Telegraph Act/Section 69 of IT Act (for national security/public emergency, with high-level approval). Even police cannot arbitrarily collect CDRs without justification, as ruled by courts (e.g., Karnataka High Court in 2025 emphasized this violates privacy).

Remedy: If your CDRs were illegally obtained, file an FIR under the above sections, approach the Cyber Crime Cell, or petition the High Court for privacy violation relief.

Punishments vary based on the offender (e.g., insider vs. outsider), intent, and misuse (e.g., blackmail adds extra charges). Consult a lawyer for case-specific advice, as evidence of unauthorized access is key.

Special Suggestion By Chanakya Detective Chief Investigator Detective Vikas Sonkar

My suggestion, which i am giving you, based on my 25 years pour experience of investigation trade and which is dynamic as everyone in the world, with the upgradation of technology and as AI and IT revolution changing dynamics of today.

As now every one has more than one number

2. Now we have VOIP voice over internet protocol means WhatsApp Viber Botim Telegram Signal and even social media like Instagram and facebook also provide you the option of calling and private rooms and other such application, Where CDR is just a illusion and didn't record any thing except the internet usage. And if one doing anything wrong they use such app.

3. Under the Indian Evidence Act, 1872 (now largely replaced by the Bharatiya Sakshya Adhiniyam, 2023, it is not admissibility in the court due to the legal complexity mentioned above and it could fire back, because The person who illegally obtained/disclosed the CDR (e.g., via bribery or hacking) faces separate criminal liability (under IT Act Sections 72/72A, Telegraph Act, etc.), but this does not invalidate the evidence itself.

Not only the private detective evidence, but every evidence which is presented in the trail court, Every piece of evidence presented in a trial court must pass through a strict legal framework to ensure it is authentic and reliable as per BSA 2023. It's a very legal and technical question and can't not be defined without facing a legal technicalities. So without dive into the law, here let's talk about the cracs of the law. If we talk about the evidence, So we can divide into two parts first Primary evidence and secondary evidence.

Primary evidence
Primary evidence as per Section 62 of the Indian Evidence Act, 1872 and Bharatiya Sakshya Adhiniyam (BSA), 2023. Under the new law, primary evidence is covered under Section 57.

Primary evidence refers to the original document (Certificate Contract Agreement Digital Proof like Photo Video) itself produced for the inspection of the Court. The law prefers the original because, as it is the most reliable and least likely to have been tampered with or misinterpreted.

Direct Primary Status: Under the old act, electronic records often required special certificates (Section 65B) to be treated as evidence.

Section 57 of BSA now explicitly states that electronic or digital records—including those stored in multiple files, video recordings, or data from smartphones and servers—are considered primary evidence if they are produced from proper custody.

Secondary Evidence
In Indian law, Secondary Evidence refers to any evidence that proves the contents of an original document when the original itself cannot be produced. While primary evidence is the "best" evidence, secondary evidence is considered "alternative" or lower-quality evidence and is only admitted under specific legal conditions.

Similar to primary evidence, the rules for secondary evidence have recently transitioned from the Indian Evidence Act (IEA), 1872 to the Bharatiya Sakshya Adhiniyam (BSA), 2023.

Form of Secondary Evidence
Defined under Section 63 IEA / Section 58 BSA
Certified Copies
Mechanical Copies
Compared Copies
Counterparts
Oral Accounts

New in BSA (Section 58): Includes oral or written admissions made by a party about the contents of a document.

Detective Vikas Sonkar Opinion on the Topic

As the student of law and practicing private detective, which is the rare combination, I can suggest you to take the middle path after applying and considering both expertise.

Anonymity and Type of Evidence
Almost all the time private detective provides the evidence in the form of photographic, videographic and sometime documentary evidence (copies requested from the Actual issuing authorities), Which come under the Primary Evidence as per section 57 of Bharatiya Sakshya Adhiniyam (BSA), 2023. So it is very much admissible under the trail court or can be present at the any level of court in India. With or without giving specific private detective name.

Time Calculation and Complexity
But as per my suggestion you should not mentioned private detective agency name, because it will make the process more time consuming and lengthy as court can ask to call a private detective agency in the court and agency may or may not be comfortable to appear in the court and how long they will continue this.

Increase the Costing
They can charge a sperate amount for the same, Which can affect your cost of fighting the case.

Make it a Primary Evidence
As per the burden of proof, you are the most Eligible person to gather this evidence and that hardly matters that who obtains these proof, which matter is the given proof and evidence should be authentic and original, and obtain and present as per the given guideline under Bharatiya Sakshya Adhiniyam (BSA), 2023.
