How to Verify a Private Detective Agency in the Czech Republic

Hiring a private detective often means disclosing sensitive personal, legal, financial or commercial information. Before engaging an investigator, clients should confirm who will perform the work, whether the provider is legally authorized and whether adequate liability insurance is in place.

A professional-looking website, a Prague address or a statement that an agency operates legally is not proof of authorization. Czech private detective services are regulated, and clients can independently verify the provider through public registers.

Are private detective services licensed in the Czech Republic?

Yes. Under Act No. 455/1991 Coll., the Trade Licensing Act, Služby soukromých detektivů — Private Detective Services — is a concessionary trade. This category covers activities including:

• locating people and property;
• establishing facts that may be used as evidence;
• obtaining information concerning individuals, companies or their property;
• gathering information connected with debt recovery;
• identifying unlawful conduct threatening trade secrets; and
• collecting and evaluating information for clients who demonstrate a legitimate interest.

An ordinary general trade authorization is not sufficient. The legal entity or individual providing these services must hold the appropriate concession.

What is required to obtain the concession?

The entrepreneur, or its appointed responsible representative, must satisfy the applicable statutory requirements. Depending on the qualification route used, these generally include appropriate university, higher-professional or secondary education; relevant professional experience; professional qualifications recognized under Czech law; integrity and reliability requirements; and compliance with the conditions governing people who actually perform detective work.

The concession is administered and issued by the competent Czech trade-licensing authority. The legally significant evidence is the active authorization recorded in the Czech Trade Register.

Clients should be cautious about vague statements such as “internationally licensed,” “licensed investigators” or “operating under European law.” These statements do not establish that the person or company providing the Czech investigation holds the required Czech authorization.

What must a detective agency disclose on its website?

Section 435 of the Czech Civil Code requires an entrepreneur publishing information through remote access, including a commercial website, to disclose identifying information. A Czech business website should normally identify:

• the complete legal name of the business;
• its registered office;
• its assigned identification number, or IČO;
• the public register in which it is recorded; and
• for a company registered in the Commercial Register, the relevant court, section and file number.

A trading name or brand by itself is not enough. Potential clients must be able to determine which legal entity is operating the website and which entity will enter into the contract. The identifying information may appear in the footer, contact page, terms and conditions, imprint or another reasonably accessible legal-information section. Hiding the legal provider behind a brand name prevents clients from conducting meaningful verification.

Must the detective concession be displayed on the website?

Czech law does not generally require an agency to publish a scanned concession certificate or a special “private detective licence number” prominently on every webpage. Nevertheless, before the service is provided or the contract is concluded, the provider must make required identifying and authorization information available to the client. Depending on the circumstances, this information may be supplied on the website; in an engagement letter, contract or other document; at the location where the contract is concluded; or directly in response to the prospective client.

Where an activity requires official authorization, the provider should disclose the relevant authorization and the authority responsible for it. The client should also receive enough information to identify the concession holder and verify the authorization independently. A statement that an agency is “fully licensed” is not independently verifiable unless it identifies the legal person holding the authorization (see Section 10 of Act No. 222/2009 Coll., on the Free Movement of Services).

Are Czech private detective agencies required to be insured?

Licensing and insurance are separate issues. The current Czech Trade Licensing Act does not expressly make professional-liability insurance a universal condition for obtaining the Private Detective Services concession. A provider may therefore hold the required concession without necessarily carrying adequate professional or public-liability insurance. Clients should not assume that “licensed” automatically means “insured.”

Where an agency represents that it is insured, the client should ask for a current certificate of insurance and confirm the exact insured legal entity; the name of the insurer; the policy number; the effective and expiration dates; the insured activities; the geographical territory; the indemnity limit; material exclusions; and whether employees and subcontractors are covered.

The legal entity named on the insurance certificate should correspond with the entity holding the concession and entering into the client contract. Insurance issued to a related company, marketing brand or separate billing entity may not cover the investigative work. Applicable liability-insurance information should be made available to the service recipient before contracting, including the provider and the material and territorial scope of coverage.

How can clients verify a detective agency step by step?

The most reliable starting point is the agency’s IČO. Clients can use it to search the public portion of the Czech Trade Register.

Step 1: Identify the legal provider

Obtain the complete legal name, the IČO, the registered office, the name of the contracting entity and the name of the entity that will actually conduct the investigation. If the website provides only a brand name, ask which company or individual operates the brand.

Step 2: Search the Czech Trade Register

Use the official Czech Trade Register public search. Search using the IČO whenever possible — names may be similar, but the IČO uniquely identifies the business. The record should show an active authorization for Služby soukromých detektivů. Confirm that the authorization belongs to the exact entity offering and contracting for the investigative services. A general consulting, research, security or miscellaneous-services trade is not the same authorization.

Step 3: Check the Commercial Register

For an s.r.o., a.s. or another registered legal entity, search the Czech Ministry of Justice Public Register. Verify the current legal name, registered office, IČO, company status, authorized directors, the Commercial Register section and file number, and whether the person signing the agreement is authorized to represent the company.

Step 4: Compare all documents

The same legal entity should normally appear on the website, the proposal, the engagement agreement, the invoice, the Trade Register record, the privacy notice, the insurance certificate and the bank-payment instructions. Differences do not automatically prove wrongdoing, but they require a clear written explanation. Clients should understand who is contracting, who is investigating, who controls the personal data and who bears financial responsibility if something goes wrong.

Questions to ask before hiring a private investigator

• What is the full legal name and IČO of the entity I will contract with?
• Does that exact entity hold the active concession “Služby soukromých detektivů”?
• May I receive a current Trade Register extract?
• Who will actually perform the investigation?
• Are employees and subcontractors properly qualified for the work assigned to them?
• Will any work be subcontracted to another company or individual?
• Is the agency covered by professional or public-liability insurance?
• May I receive a current insurance certificate?
• Does the policy cover private investigations in the Czech Republic and any other countries involved?
• Does the policy cover surveillance, data work, employees and subcontractors?
• Which legal entity will issue the invoice and receive payment?
• Who will be the GDPR data controller?
• Where will reports, photographs, video and personal information be stored?
• How long will the evidence be retained, and how will it be destroyed?
• Will the agency provide a written engagement agreement defining the legal objective, scope, price and limits of the investigation?

A legitimate professional provider should be able to answer these questions clearly.

Warning signs when choosing a detective agency

Clients should proceed cautiously when no legal entity or IČO appears on the website; the site identifies only a brand; the agency claims to be licensed but will not identify the concession holder; the company accepting payment differs from the purported investigator without explanation; the Trade Register shows no active Private Detective Services concession; the agency refuses to provide an insurance certificate; the insurance covers a different legal entity; the provider relies only on association membership or foreign credentials; the provider will not explain its subcontractors or GDPR responsibilities; or the agency asks for payment before providing a written agreement. Membership in a professional association may be useful, but it does not replace the Czech concession.

Final client checklist before you pay a deposit

Before paying a deposit or disclosing sensitive information, confirm that the legal provider is clearly identified; its IČO matches the public records; its Private Detective Services concession is active; the contracting and invoicing entities are explained; its insurance is current and covers the intended work; its investigators and subcontractors are appropriately qualified; its GDPR and evidence-handling procedures are documented; and the scope, price, lawful purpose and reporting requirements are contained in a written agreement.

Independent verification takes only a few minutes. It can prevent clients from entrusting sensitive information, evidence and substantial fees to a provider whose identity, authorization or insurance cannot be confirmed.
