Prague Corporate Due Diligence: What a Thorough Company Check Should Cover

Key points

• Match the depth of the check to the decision: a supplier onboarding and an acquisition need different levels of work.
• Czech public registers, the collection of deeds and the insolvency register are the foundation of any company check.
• Unrestricted public access to the Czech beneficial ownership register ended on 17 December 2025. Plan for that.
• Check national and EU sanctions as well as unreliable VAT payer status and property records.
• Registers tell you what has been filed. Interviews, reputation work and site visits test whether it is true.
• Personal data about directors and owners is still protected by GDPR during due diligence.

Start with the decision, not the database

Corporate due diligence in Prague can mean a quick identity check on a new supplier or months of work before buying a stake in a business. The right scope depends on what you are about to commit, what could go wrong and how much of the risk you can recover if it does. Write down the decision, the deadline and the questions that must be answered before you sign.

A useful way to think about scope is in layers. The first confirms who the company is and who runs it. The second tests its financial position, ownership and legal history. The third goes beyond paperwork to reputation, relationships and the people behind the business. Many transactions only need the first two. Some need all three.

The Czech registers every check should cover

The public register (veřejný rejstřík), searchable through the Ministry of Justice portal at or.justice.cz, shows the company’s registered details, statutory body, shareholders where recorded and the history of changes. The collection of deeds (sbírka listin) holds filed documents such as articles of association and financial statements. Companies are required to file financial statements, although what they must publish depends on their size category. Gaps, late filings and frequent changes of directors are worth asking about.

The insolvency register at eisir.justice.cz shows insolvency proceedings and related court documents. Read the actual status rather than the headline: a petition is not a decision that the company is insolvent, and an old case may be closed. For enforcement against a company or individual, the Central Register of Executions run by the Czech Chamber of Enforcement Officers (ceecr.cz) is public and charges a fee. It does not cover every kind of debt collection.

If property matters to the deal, the Cadastre of Real Estate (nahlizenidokn.cuzk.gov.cz) provides ownership and encumbrance information. Access conditions for owner details have changed recently, so check the current login requirements. For VAT registered businesses, the Financial Administration’s VAT register shows whether a company is flagged as an unreliable VAT payer and lists its published bank accounts, which is useful before you pay an invoice.

Beneficial ownership after December 2025

Knowing who ultimately owns and controls a company is often the most important question, and in the Czech Republic it has become harder to answer from a public search. Following the Court of Justice of the EU’s 2022 judgment in WM and Sovim, which struck down unrestricted public access to beneficial ownership information, the Ministry of Justice closed general public access to the Czech register on 17 December 2025.

Access now remains for the company itself, for authorised users including obliged entities under the anti money laundering rules, and for members of the public who show a legitimate interest to the competent court. In practice, most buyers and partners will need to ask the target to provide its own register extract and supporting documents, then test the answer against shareholder records, group charts and other filings.

Sanctions and anti money laundering checks

Screen the company, its owners and its directors against EU sanctions and the Czech national sanctions list. The national list is maintained under Act No. 1/2023 Coll., while Act No. 69/2006 Coll. governs how international sanctions are implemented, with the Financial Analytical Office (FAÚ) as a key authority. The EU Sanctions Map is a helpful starting point, but the binding legal acts are what count.

If you are an obliged entity under the Czech AML Act (No. 253/2008 Coll.), such as a bank, an auditor or certain advisers, you have formal customer identification and due diligence duties. Other businesses do not carry those statutory duties, but the same checks are still good practice before a significant transaction.

Going beyond the registers

Registers record what has been filed, not whether it is accurate. Deeper due diligence tests the story. That can include adverse media research in Czech and other relevant languages, litigation searches, a review of the directors’ other companies and past insolvencies, discreet enquiries with people who have dealt with the business and a visit to confirm that an address is a real operating site.

Keep this work proportionate and lawful. Directors and owners are people with rights under GDPR. Collect what is relevant to the decision, record your sources and avoid leaked databases, pretexting or anything that relies on deception. A finding you cannot explain the source of is of little use in a negotiation or a dispute.

What a useful due diligence report looks like

A good report starts with a short summary of the answer to each question you asked. It then sets out the evidence, the source and date of each item, and a clear distinction between confirmed facts, unresolved points and allegations. Where something could not be checked, the report should say so rather than leave a silence that looks like a clean result.

The most valuable part is often the list of questions to put to the other side before signing. Discrepancies are not always signs of wrongdoing. Many have ordinary explanations, and asking about them early is part of a healthy negotiation.

A Prague due diligence checklist

1. Confirm the legal name, IČO, registered office and statutory body in the public register.
2. Review filed financial statements and key documents in the collection of deeds.
3. Search the insolvency register and, where relevant, the Central Register of Executions.
4. Request the beneficial ownership extract and test it against shareholder and group records.
5. Screen the company, owners and directors against EU and Czech sanctions lists.
6. Check unreliable VAT payer status and published bank accounts before paying.
7. Verify property, licences or permits the deal relies on.
8. Decide whether reputation research, interviews or a site visit are needed for this decision.

Common questions

What does corporate due diligence in Prague usually include?

At a minimum, checks of the public register, collection of deeds, insolvency register, sanctions lists and VAT status. Deeper work adds beneficial ownership analysis, litigation and adverse media research, interviews and site visits.

Can I still see who owns a Czech company?

Shareholders often appear in the public register. Since 17 December 2025, the beneficial ownership register is no longer open to the general public. Access is available to the company itself, to authorised users and to people who show a legitimate interest to the court.

Is a clean insolvency register search enough?

No. It shows insolvency proceedings, not everyday unpaid debts or cash flow problems. Combine it with financial statements, enforcement records and questions to the company.

Do Czech AML rules require my company to do due diligence?

Only if your business is an obliged entity under Act No. 253/2008 Coll. Other businesses are not bound by those statutory duties, though similar checks are still sensible before a material transaction.

How long does corporate due diligence take?

It depends on the scope, the number of entities and how quickly documents are provided. A basic register check is much quicker than a full review before an acquisition. Agree the scope and timetable in writing at the start.
