Cadastral Defects That Can Block Your Ownership Declaration: Pre-submission Checklist
Published 8 November 2026
An ownership declaration (prohlášení vlastníka) can be blocked chiefly by discrepancies between the Czech Land Registry (katastr nemovitostí) records and reality: incorrectly registered buildings, mismatched land parcels, unclear ownership, or registered restrictions. Most of these defects can be identified from publicly available data before you submit. This article outlines what to check and the order in which to check it.
Summary
- Ownership declarations are filed with the Czech Land Registry (katastr nemovitostí), and defective initial records can result in rejection or delays under Czech Civil Code Act No. 89/2012 Coll. and Cadastral Act No. 256/2013 Coll.
- Common obstacles include incorrect building registration, mismatch between land parcel and building, unclear ownership, and registered restrictions.
- Begin verification using the public certificate of ownership (list vlastnictví) and compare it with the actual building and its documentation.
- Remedying defects before submission is cheaper and faster than addressing issues after rejection.
- Comprehensive verification is achieved through the Audit and Plan phase, with results delivered within 6 weeks.
Why the Land Registry record determines success of the declaration
An ownership declaration (prohlášení vlastníka) depends on the building, land parcel, and owner all being correctly registered in the Czech Land Registry (katastr nemovitostí) with no contradictions. The registry office assesses whether it can allow the declaration based solely on what is recorded there.
Under §1166 onwards of the Czech Civil Code Act No. 89/2012 Coll., an owner may divide a building into individual units by making an ownership declaration that is then registered. Ownership rights to the units arise only upon registration. If the office encounters a defect during the process, it may suspend proceedings, request remediation of deficiencies, or reject the registration under the Cadastral Act No. 256/2013 Coll. Rejection means lost time and the need to file again.
Pre-submission verification of records is therefore the first step in the entire transformation process, not mere formality. An overview of all phases can be found on the How it works page.
Most common cadastral issues in apartment buildings
Older apartment buildings commonly exhibit the same types of defects, which often reflect historical recording issues rather than current building condition.
- Incorrect building registration. A building is registered as a different type of structure or with a use that does not match reality (for example, as a residential building without corresponding use classification in the registry).
- Mismatch between building and land. The building stands partially on a different parcel than recorded, or the land underneath and surrounding land belong to a different owner.
- Incorrect owner information. Failure to register inheritance transfers, discrepancies in name or address, or co-ownership with unresolved share distribution.
- Registered restrictions. Mortgages, easements, restrictions on dealing with the property, enforcement proceedings, or notes about ongoing legal disputes.
- Unregistered building modifications. Loft conversions, extensions, layout changes, or combining units that are not documented or registered.
- Numbering inconsistencies. House number, address, and parcel designations that do not match each other across different records.
Checklist: what to verify before filing the declaration
It is advisable to conduct the verification in a fixed order, moving from public data to the building documentation.
- Certificate of ownership extract. Information about the building, land, and owners can be found in the public registry search. Verify that all parcels under the building and related land are registered and belong to the same owner.
- Part B1 and Part C of the certificate of ownership. These sections record the properties and restrictions on ownership rights. Note down every mortgage, easement, annotation, and enforcement entry.
- Cadastral map versus reality. Compare the building outline on the map with the actual layout. Differences may require a new geometric plan.
- Type and use classification of the building. Check that the registry entry matches the actual use of the building.
- Documentation of actual condition. Compare existing drawings with the current state. Any unrecorded structural modification is a risk, even from the perspective of the Building Act No. 283/2021 Coll.
- Areas and unit boundaries. Units must be defined in the declaration so they can be clearly identified (§1159 onwards of the Civil Code). Floor areas must therefore be based on verified measurements.
- Ownership structure. If the building is in co-ownership, clarify who will file the declaration and how. For inherited shares, ensure the inheritance has been properly registered.
Restrictions and third parties: what requires separate attention
A registered mortgage or enforcement proceeding does not necessarily prevent the declaration, but always requires separate resolution before filing.
If the building is mortgaged, you will typically need to account for the mortgagee and how the mortgage will affect the individual units. A restriction on dealing with the property or enforcement proceeding under the Enforcement Code Act No. 120/2001 Coll. can make the declaration virtually impossible until the matter is resolved. Similarly, you should check whether the owner is in insolvency proceedings (Insolvency Act No. 182/2006 Coll.), which restricts dealings with assets.
| Registry finding | Typical impact | Action required beforehand |
|---|---|---|
| Mortgage | Agreement with mortgagee needed | Establish mortgage terms and procedure |
| Enforcement proceeding, restriction on dealing | Blocks dealings with the building | Check enforcement status and resolution options |
| Easement | Must be accounted for in the declaration | Verify scope and affected building areas |
| Note of ongoing proceedings | Uncertainty about ownership or condition | Establish the subject and status of proceedings |
Specific assessment always depends on the content of the entries, so we recommend consulting a lawyer.
How to remedy defects and in what order
First, ownership defects and restrictions are resolved; only then the building, areas, and the declaration text itself.
- Complete any inheritance proceedings and register the correct owner.
- Resolve mortgages and enforcement entries.
- Correct building and land registration records, if necessary by obtaining a new geometric plan.
- Update the documentation of actual building condition and verify any unauthorised modifications.
- Measure unit areas and prepare the declaration text.
The right sequence saves time because later steps build on earlier ones. The overall economic logic is clear: the typical difference in value between selling a building as a whole and selling units individually is +20–40 %, though the exact figure will depend on a feasibility study. You can get a rough estimate in our building potential calculator.
What to do now
Begin with the certificate of ownership extract and existing building documentation and have them professionally assessed before you file your application.
- Download a current certificate of ownership extract for the building and all related land parcels.
- Prepare building documentation, any permits, and any inheritance or purchase documents.
- List any mortgages, enforcement proceedings, and easements you are aware of.
- Check whether the actual building condition matches the documentation.
Legal and cadastral viability is verified by the Audit and Plan service, a paid feasibility check with results within 6 weeks. The project passes through three gates (legal, permit, sales gate) and proceeds to the next phase only with confirmed figures.
