Client Checklist: What to Prepare Before Hiring a Private Investigator in Prague

Most people who pick up the phone to a private investigator have never done it before. The first call usually feels awkward, and that often costs the client time and money: either the brief is too vague to scope, or the wrong information is shared and good leads get missed. This checklist is what we wish every new client had in front of them before they call us — or any other licensed Czech investigator.

1. Define the question you actually want answered

"I want to know what my husband is doing" is a feeling, not a brief. "I want to know whether my husband is meeting a specific person at a specific address during business trips to Brno" is a brief. The more specific the question, the cheaper and faster the answer. Write the one-sentence question down before you call.

2. Gather identifiers for every subject

For each person, company or vehicle the investigation will touch, prepare what you can:

• Individuals: full name, date of birth, last known address, employer, phone numbers, email addresses, social-media profiles, recent photograph.
• Companies: business name, IČO (Czech company ID), registered address, names of statutory representatives, any sister or parent companies you suspect.
• Vehicles: registration plate, make, model, colour, where it is usually parked.

3. Document the timeline

Dates matter more than narrative. Prepare a simple timeline:

• When did the suspicious behaviour begin?
• What specific incidents prompted you to call?
• What dates, times and locations are already known?
• What upcoming dates matter (court hearing, claim deadline, board meeting, custody hearing)?

4. Bring the existing paper trail

Investigators do not start from zero. Whatever you already have shortens the engagement:

• Insurance claim file, medical reports, accident report.
• Employment contract, NDA, non-compete clause.
• Court filings, judgments, decisions of the executor.
• Email or message screenshots (with the original device available if possible — exports get challenged).
• Bank statements, invoices, contracts that triggered the suspicion.

5. Decide who is the client

Czech investigators distinguish between three contracting parties: an individual, a company, and a law firm. Engaging through a law firm extends attorney-client privilege over the investigative product — frequently worth the modest extra cost in litigation-bound matters.

6. Be honest about what is lawful

Czech law does not permit a licensed investigator to:

• Place a GPS tracker on a vehicle that is not yours.
• Hack accounts, intercept calls or read messages without the owner's consent.
• Access bank, medical or telecommunications records.
• Enter an enclosed private property to observe a subject.

If a competitor has promised these things, walk away. The evidence is unusable in court and exposes both client and investigator.

7. Ask the investigator the right questions

• Which Czech business licence (živnostenské oprávnění) authorises this work?
• Are you the person who will run the case, or are you brokering it?
• Is the team in-house or sub-contracted, and how is the chain of custody preserved?
• What is the deliverable: an oral debrief, a written report, court-ready evidence with witness availability?
• How is GDPR addressed — who is controller, who is processor, where is the legitimate-interest assessment?

8. Understand pricing structure

Reputable Prague firms quote in one of three ways: hourly fieldwork rates with a written cap, fixed-fee deliverables for defined products (background check, asset trace, EDD report), or a phased budget with go / no-go decisions between phases. Expect a written engagement letter, an advance, and itemised reporting against the budget.

9. Agree on communications

Decide before fieldwork starts: how often you want updates, on which channel, and who else may receive them. Investigations involving family or workplace are often compromised because an update was forwarded to the wrong person.

10. Set a clear endpoint

An investigation without an endpoint becomes a retainer. Agree what the answer "yes", "no" or "inconclusive" looks like, and what happens then.

Clients who walk into the first meeting with this checklist completed routinely cut their fieldwork hours by a third and double the quality of the deliverable. Exero Group's bilingual intake team will guide you through anything on the list you cannot complete on your own.
