What land registry issues can obstruct converting a multi-flat building into separate units

Why problems appear specifically with the Land Registry

The Land Registry office (katastrální úřad) assesses whether the application and supporting documents comply with law and the Land Registry record; thus any discrepancy results in a request for correction or rejection.

Ownership of a property passes only upon registration in the Czech Land Registry (katastr nemovitostí). The same applies to the creation of units: until the owner's deed is registered, there is only one property. Under the Land Registry Act (No. 256/2013 Coll.), the office cannot decide on registration earlier than 20 days after notifying the owner. The average registration time is around 22 days, but this applies to a flawless application. If the office finds a defect, the proceedings extend by the time needed for correction.

From a project perspective, this presents a risk of delay and cost. The difference in value between selling a building as a whole and selling individual units is typically +20–40%; the precise figure will be determined only upon feasibility study. Delays at the Land Registry do not eliminate this benefit, merely postpone its realisation.

Unclear land boundaries and outdated survey plans

The land plot under the building must be clearly defined in the Land Registry, otherwise a reliable deed cannot be prepared nor can it be clearly described what belongs to each unit.

With older multi-flat buildings, it can happen that the actual fencing does not match the Land Registry map, the plot is recorded in an outdated format, or part of the courtyard or garden belongs to another owner. An outdated survey plan then does not correspond to the current state of the building—for instance, after an extension or ground-level alteration.

• Verification: Compare the Land Registry map, extract and actual conditions on site.
• Correction: Engage a qualified surveyor to prepare a new survey plan and have it certified under the Land Registry Act (No. 256/2013 Coll.).
• Boundary dispute: Should neighbours disagree, an agreement is necessary; if needed, court proceedings—this is the longest option.

Resolution time depends on whether this is a simple update or a dispute. The former typically takes a matter of weeks; the latter can take several months.

Unregistered or incomplete buildings and missing documentation

The building must be registered in the Land Registry to the extent that you wish to divide it, and reliable documentation must exist.

Attic conversions, extensions or layout changes made without registration or permission are common problems. This creates a discrepancy between the Land Registry, documentation and reality. Under the Building Act (No. 283/2021 Coll.), it must be assessed whether the current state can be legalised, or if additional permission or other action is required.

According to the Civil Code (No. 89/2012 Coll.), the owner's deed must include, among other things, a description and definition of the units and floor plans. If documentation is missing, a survey and documentation of the actual construction must be prepared.

1. Establish what is recorded in the Land Registry versus what actually exists.
2. Locate the building completion certificate and building permit from the building authority archive.
3. Resolve discrepancies through legalisation or registration of changes.
4. Only then arrange for documentation for the deed to be prepared.

This phase corresponds to the 'permit gate' in the process described on the page How it works.

Mortgages, enforcement proceedings and other entries in the ownership record

A mortgage on the building does not automatically prevent conversion, but usually the consent of the creditor is needed and the mortgage must be properly allocated to the units.

A mortgage or other charge does not cease upon creation of units; it must be resolved how it will apply to individual units and how it will be released upon sale of each. In practice, an arrangement is made with the creditor for releasing the charge per unit upon payment of the agreed portion of debt. Terms depend on the bank agreement.

More serious obstacles are enforcement or insolvency entries. Property subject to enforcement under the Enforcement Rules (No. 120/2001 Coll.) or insolvency under the Insolvency Act (No. 182/2006 Coll.) is subject to disposal restrictions and without resolving these, registration typically will not proceed. Similarly, real burdens (such as easements) and lease arrangements should be checked, as these can affect saleability.

Resolution time depends on the creditor's willingness and the debt amount; no firm timeframe can be given.

Mismatched shares and defects in the owner's deed

Shares in the common parts of the building must be stated correctly and consistently in the deed; otherwise, the Land Registry office will reject registration or request correction.

The Civil Code (No. 89/2012 Coll.) assumes that the share in common parts is determined by the ratio of the unit's floor area to the total, unless the deed specifies otherwise. Errors arise from incorrect area measurements, omission of basements or attic spaces, or when shares do not sum to the whole. Conflicts between the deed text and attached plans also cause problems.

If the building is jointly owned by multiple persons, all owners must sign the deed. The former general right of first refusal for co-owners has been abolished; for a share acquired by inheritance, this right exists only for six months from the date the joint ownership arose (§1124 of the Civil Code). Inheritance or unresolved ownership matters must therefore be clarified before filing.

What the solution process looks like and how long it takes

The total time depends mainly on preparing documentation, not on the registration itself, which averages around 22 days.

1. Research: Land Registry extract, map, deeds and documentation.
2. Defect list: What discrepancies exist and who must resolve them (surveyor, building authority, creditor, co-owners).
3. Correction: New survey plan, legalisation, bank agreement, share adjustment.
4. Registration application: Owner's deed with supporting documents.
5. Land Registry proceedings: Decision not earlier than 20 days after notification; if defects are found, a request for correction and suspension follow.

Simple updates take less time; boundary disputes or building legalisation typically take considerably longer. Precise timescales can only be stated reliably after assessing the individual property. When selling units later, also address tax implications; these generally depend on the holding period and residential use—verify details with the Tax Authority or a tax advisor (Act No. 586/1992 Coll.).

What to do now

Start by checking the documentation; defects are cheapest to resolve before further investment in the project.

• Obtain a current Land Registry extract for both the building and the land plot.
• Prepare the building completion certificate, plans and any older survey plans.
• Gather loan and mortgage agreements and a summary of lease arrangements.
• If jointly owned, clarify who will sign the deed.
• Arrange an assessment as part of the Audit and Plan service.
