How to Find the Owner of a House or Plot by Address Without Purchasing a Land Registry Extract
Published 11 November 2026
The easiest way to find the owner of a house or plot is through free public access to the Czech Land Registry (Katastr nemovitostí), where you enter the address or plot number and see the owner without ordering a paid official extract. If the registry doesn't provide what you need, you can try direct contact, enquire at the local municipal office, or check the Business Register for companies. You need an official extract only when you must document the data in negotiations or before purchase.
Summary
- The Czech Land Registry is public (Act No. 256/2013 Coll.), and you can find the owner online for free using the address or plot number.
- A land registry extract is an official document; free public access is usually sufficient to obtain initial contact details.
- Municipalities typically don't disclose personal data, but they can advise on plot numbers and procedures; the Business Register helps with company information.
- Before purchase, offer or contract, always verify ownership in the land registry and handle data in accordance with data protection rules.
Czech Land Registry is Public: Find the Owner for Free Online
The most reliable way to find an owner is through public access to the Czech Land Registry, which is free and requires no extract.
The Czech Land Registry (Katastr nemovitostí) is a public register under Act No. 256/2013 Coll. On the registry's website, you enter the building address, property number or plot number and see information about the property, including the owner. For individuals, you typically see their name and residence address; for companies, the name and registered office. Identity numbers are not displayed.
- Open the public registry access (nahlížení do katastru) on the Czech Office for Surveying, Mapping and Cadastre (ČÚZK) website.
- Search for the building by address, or the land by cadastral area and plot number.
- Open the property details and the link to the ownership certificate (list vlastnictví).
- Check whether there is one owner or multiple co-owners or joint marital property.

When Public Access Is Enough and When You Need an Extract
Public access is fine for finding contact details, but a land registry extract is an official document you need for legal transactions.
Data in public access are informational. If you present them to a bank, court, authority or the other party in a contract, an extract or certified copy is usually required. Before buying a property, do not rely only on what someone has told you. Ownership rights transfer only by registration in the Czech Land Registry (Act No. 256/2013 Coll.), so the entry in the register is what counts, not an oral statement or a signed contract alone.
| Situation | Public Access Sufficient | Extract Recommended |
|---|---|---|
| Finding a neighbour's name or landowner | Yes | No |
| Finding contact for an informal offer | Yes | No |
| Dealing with authorities or courts | No | Yes |
| Purchase and registration in the registry | As initial check | Yes |
Alternative Methods If the Registry Doesn't Suffice
If the registry shows the owner without usable contact details, several supplementary and perfectly standard methods can help.
- Direct contact. Ring the doorbell, ask neighbours, or leave a note in the letterbox addressed to 'the property owner' with your contact details. For unenclosed land, this is often the fastest route.
- Municipal or city office. The office is usually not obliged to disclose personal data and often legally cannot without a lawful reason. However, it can help determine the plot number, address or confirm whether the land belongs to the municipality. If the plot is owned by the municipality, the municipality itself is the owner.
- Business Register. If a company is registered in the land registry, find its address, managing director and contact details in the public Business Register (rejstřík) on the justice.cz portal.
- Monitoring changes. After registration, the land registry offers a notification service for changes to selected properties. Use it if you want to know when ownership changes.
Do not regard any of these methods as a guarantee that you will find the owner. Registry entries may not reflect current residence, and in inheritance cases, the ownership change may still be pending.
Data Protection and Respectful Approach
Public data doesn't mean they can be used in any way, so contact the owner appropriately and only regarding the property.
Personal data from the land registry are subject to data protection rules, and you may use them only for a purpose consistent with the reason for obtaining them—for example, to make a purchase offer. Do not pass them on or collect them without reason. General information is available from the Office for Personal Data Protection (Úřad pro ochranu osobních údajů). If the owner asks you not to contact them further, respect that request.
When first contacting them, be brief: who you are, which property concerns you, what you are offering and how to reach you. Do not ask for their data and do not pressure them to decide quickly.
How Owners Can Check Their Own Details
An owner can easily check what the land registry publicly shows about their property and themselves.
Simply search your own address or plot number in the public registry access. Check your name, share, type of ownership and also any rights or restrictions affecting the property, such as a mortgage (zástavní právo), servitude (věcné břemeno), or a note about enforcement or insolvency proceedings. This is what potential buyers and interested parties will see. If you find discrepancies—for example, an incorrect residence address—address them with the relevant cadastral office.
Ignorance of restrictions is a common reason why sales are delayed. It is therefore good to know the state of your ownership certificate before negotiating with a buyer.
