How to File an Owner's Declaration with the Land Registry Authority
Published 28 October 2026
You file an owner's declaration as an attachment to your application to register units at the relevant Land Registry office (Czech Land Registry — Katastr nemovitostí). The Land Registry cannot decide before 20 days have passed since notification of the owner (Land Registration Act No. 256/2013 Coll.), and the average registration time is approximately 22 days. The quality of your documentation before submission will determine whether the process runs smoothly or ends with a request for corrections.
Summary
- The declaration is filed with the registration application; units only come into being upon registration at the Czech Land Registry.
- Most of the work is done before submission: documentation, defining units, determining shares and verifying signatures.
- The Land Registry cannot decide before 20 days after notification; average registration takes approximately 22 days.
- Most common issues: data discrepancies, missing attachments and requests to correct defects.
- The declaration is just one step; its value depends on prior feasibility analysis.
What the Owner's Declaration Triggers
By filing an owner's declaration under the Civil Code No. 89/2012 Coll. (§ 1158 et seq.), you divide a building into units—flats and non-residential spaces—and determine the common parts of the building and the shares attributed to each unit. What was a single ownership of the whole building becomes a set of separately tradeable units.
Importantly, units only come into being legally upon registration at the Czech Land Registry (Katastr nemovitostí). Until then, the division exists only on paper. For an owner of a rental building planning to sell units individually, registration of the owner's declaration is therefore a critical milestone of the entire project.
Step 1: Preparing Documentation Before Submission
Your registration application is only as good as your documentation. Before filing, prepare the following:
- Text of the declaration meeting the requirements of the Civil Code No. 89/2012 Coll.: a description of the building and land, definition of units, specification of common parts and the shares attributable to each unit.
- Floor plans and measured areas of each storey, clearly showing which spaces form each unit. Shares are typically derived from floor areas, so any measurement error will affect the entire document.
- Current extract from the Land Registry and proof of ownership; verify the status of the ownership certificate in the Land Registry.
- Consents from third parties if required—for example, from mortgage creditors whose mortgages are registered against the property.
Independently verify the building's compliance with planning and construction law, especially its lawful use and any structural alterations under the Building Act No. 283/2021 Coll. Discrepancies between the actual state and the Land Registry record are a common source of problems.
Step 2: Document Form and Signature Verification
The document forming the basis of the registration must meet the formal requirements of the Land Registration Act No. 256/2013 Coll. and the Civil Code No. 89/2012 Coll. In practice, this means the owner's signature must be notarised. Verify the specific requirements with a lawyer, notary or the Land Registry office before signing.
If the building is owned by multiple persons, all co-owners must sign the declaration. A missing or unnotarised signature is among the most common reasons the Land Registry requests corrections.
Step 3: Completing and Submitting the Registration Application
The declaration is filed together with the application to begin proceedings for registration of units. The form is available on the website of the Czech Office for Surveying, Mapping and Cadastre and at Land Registry offices. It requires identification of the applicant, designation of the property and specification of the right to be registered.
You may submit the application in several ways:
- In person at the Land Registry office having jurisdiction over the property,
- By post as a paper submission,
- Electronically in a manner permitted by the Land Registration Act No. 256/2013 Coll., typically with a recognised electronic signature or via a data box (datová schránka).
Attach the required documents in the required number of copies and proof of payment of the administrative fee. Verify the fee amount and payment method with the Land Registry.
Under the Land Registration Act No. 256/2013 Coll., the effects of registration are tied to the moment the application arrives at the Land Registry. The submission date is therefore important if further changes affecting the building may occur during the proceedings.
Timelines: What to Expect After Submission
After the application is submitted, the Land Registry will notify the owner. The authority cannot decide on registration before 20 days have passed since this notification (Land Registration Act No. 256/2013 Coll.). The average registration time is approximately 22 days, but this is an average, not a guarantee. A more complex building or proceedings with defects may take longer.
| Stage | What happens |
|---|---|
| Application submitted | Proceedings begin; formal requirements are checked |
| Owner notified | The 20-day period begins; decision cannot be made before it expires |
| Decision | Registration, dismissal or termination of proceedings |
| Units registered | Units come into being upon registration at the Land Registry |
If the Land Registry finds defects, it will request that you correct them and set a deadline. If you fail to do so, registration may be dismissed or proceedings terminated, and you will need to resubmit the application—typically incurring a new fee.
Common Problems and How to Avoid Them
- Data discrepancies between the declaration and the Land Registry record (plot numbers, building numbers, areas). Solution: compare everything carefully with the current extract before signing.
- Inaccurate floor measurements and resulting incorrect shares. Solution: have the survey and calculations done by a professional and verify the results.
- Missing or unnotarised signatures, especially with multiple co-owners. Solution: prepare all signatures in advance.
- Mortgages or enforcement actions registered against the property, requiring the creditor's consent or resolution before registration. Solution: check the ownership certificate for any registered burdens.
- Incomplete attachments or unpaid fees, leading to requests for correction and delays.
Delays have a financial dimension too: until units are created, they cannot be sold separately, and downstream steps—such as reservations or purchase contracts—are postponed. Build a buffer into your timeline to account for this.
The Declaration as Part of a Broader Plan
Filing the owner's declaration should not be your first step. First, establish whether dividing the building is worthwhile and what obstacles may stand in your way. Dividing a building and selling units individually typically increases value by 20–40% compared to selling the whole, but only feasibility analysis will give you the exact figure.
The output of the Audit and Plan is delivered within 6 weeks. The project passes through three gates (legal, permit, sales gate), and you only proceed to the next phase with confirmed figures; details are on the How It Works page. Further answers are in the Frequently Asked Questions section.
When you later sell the units, remember that ownership rights pass only upon registration at the Land Registry and that cash payments are limited to CZK 270,000 per day (Act No. 254/2004 Coll.). Reputable purchases therefore take place cashlessly via lawyer's escrow.
