For developers and owners of residential buildings
Dividing a building into units: the owner's declaration (prohlášení vlastníka)
We prepare the declaration dividing the building into units (prohlášení vlastníka) so that the units can be sold, mortgaged and handed over to the owners' association (SVJ) for management without later corrections. The measurement survey is carried out by our partner surveying firm, and we set up the owners' association, including its articles of association.

In brief
The declaration is a legal act by which the owner of a building (or a person holding another right in rem, e.g. a right to build (právo stavby)) divides their right to the building and the land into ownership of units (in Czech). A unit – a flat or non-residential space together with a share in the common parts – comes into existence upon registration in the Land Register (katastr nemovitostí) (Section 1164 of the Civil Code). Only then can it be transferred or encumbered as a separate immovable property by registration in the Land Register. Agreements with buyers and the financing bank can be prepared and concluded in advance.
When you need a declaration
New residential project
Units can be defined even in a building under construction, as soon as it can be registered in the Land Register (survey plan (geometrický plán), document confirming the type of use; as a rule, the building must be enclosed externally by perimeter walls and a roof). Registration of the declaration creates units under construction, which can be transferred and mortgaged even before completion.
Dividing an existing building
An apartment or office building in single ownership that you want to sell unit by unit. Or a building whose flats are to pass to individual owners.
Amending the declaration
Loft conversion, additional storey, merging or splitting of units, change of use. After units have been sold, the written consent of the affected owners and a majority of votes of all owners are usually required (Section 1169 of the Civil Code).
What the declaration contains
The required content is set out in Section 1166 of the Civil Code. The declaration must state at least:
- details of the land, the building, the municipality and the cadastral area,
- definition of the units: name, number, location and purpose of use (flat, office, garage…),
- designation and description of the common parts, including those reserved for the exclusive use of the owner of a particular unit,
- the size of the shares in the common parts,
- rights in rem and other rights and encumbrances that pass to the unit owners, for example an easement (in Czech) for a transformer station.
The declaration is accompanied by floor plans of all storeys, or diagrams of them, showing the location of the flats and common parts and the floor areas of the flats (Section 1166(2)). Floor area is calculated under Government Regulation No. 366/2013 Coll. For a maisonette, for example, the staircase is counted only by its lower projection.
Shares in the common parts can be determined according to the nature, size and location of the flat, or set as equal. Otherwise, they follow the ratio of floor areas (Section 1161). The share also determines the number of votes the owner has at the SVJ general meeting (Section 1206(1)).
How we work
Documents and quote
You fill in the form, and we check the Land Register records and your documents. We send a quote with the price and timetable within 1 business day.
Measurement survey and floor plans
Our partner surveying firm measures the building floor by floor and prepares floor plans with floor areas. If you have up-to-date documentation, we work from it.
Draft declaration
We define the units, common parts, exclusive uses and shares. Together with you, we decide what to sell as separate units, what as part of the flats and what as common parts in exclusive use.
Signing and registration in the Land Register
We prepare the application for registration and communicate with the Land Registry Office. The units come into existence upon registration in the Land Register.
SVJ and sale of units
We set up the owners' association (SVJ), prepare its articles of association and the entry in the register. We follow up with purchase agreements and escrow of the purchase price.
Owners' association: watch the fourth sale
An owners' association (in Czech) must be formed in a building with at least five units, at least four of which belong to four different owners (Section 1198(1)). After that, the Land Register will not record the transfer of a further unit until the formation of the SVJ has been proven (Section 1198(2)). Without an SVJ registered in time, sales of the project can therefore come to a halt. What counts is the number of different owners, not the number of units sold.
That is why we set up the SVJ in advance. A developer, as the sole owner of all units, can set it up alone (Section 1200(1)), and the articles of association (in Czech) then do not need to take the form of a public deed (Section 1200(4)). The SVJ comes into existence on the date of its entry in the public register (Section 1204).
Common mistakes developers make
- Unclear exclusive use
- Balconies, loggias and terraces are common parts even if they are accessible only from a flat; in that case, they are by law in the exclusive use of the owner of that flat (Section 5(1)(f) of Government Regulation No. 366/2013 Coll.). For garages and parking spaces in the building, you need to decide whether they will be a separate non-residential unit (a garage, or possibly the whole communal garage as one unit in co-ownership), part of a flat, or a common part in exclusive use. Front gardens and outdoor parking spaces lie on the land: the land can be a common part with exclusive use, or it can remain outside the apartment co-ownership. If the declaration does not describe precisely who owns what, disputes with the SVJ arise. Analysis (in Czech)
- Land
- The land on which the building stands is always a common part or, if the building stands on someone else's land under a right to build, that right to build (Section 1160(2)). Surrounding plots, such as a garden or a car park, need to be decided on deliberately.
- Shares
- A share in the common parts that is determined vaguely or incorrectly is disregarded (Section 1168(2)). Yet the shares determine the votes in the SVJ.
- Forgotten easements
- Easements, for example for a transformer station, utility lines or a right of way on foot and by vehicle, belong in the declaration as rights and encumbrances that pass to the unit owners (Section 1166(1)(c)).
- Late amendments
- After the sale, an amendment requires the written consent of every owner whose rights and obligations it affects. For an encumbered unit (e.g. by a bank's mortgage), the written consent of the holder of that right is also required if the amendment affects their rights. In addition, a majority of votes of all owners is needed for the amendment to take effect, unless it affects all of them (Section 1169(1)). Some amendments, such as a change in the use of a flat at the owner's request, are approved by a majority alone (Section 1169(2)). Analysis (in Czech)

Frequently asked questions
Short answers
Who signs the declaration dividing a building into units?
The owner of the building and the land, or a person holding another right in rem, such as a right to build (Section 1164(1) of the Civil Code). If the building is in co-ownership, all co-owners make the declaration jointly. When co-ownership is dissolved, the definition of units can also be agreed in the settlement agreement (Section 1164(2)).
Can units be created before the building is completed in the Czech Republic?
Yes, if construction has progressed far enough for the building to be registered in the Land Register (based on a survey plan; as a rule, it must be enclosed externally by perimeter walls and a roof). The Land Registry Office does not examine the stage of construction – the applicant is responsible for it, so we check the documents in advance. Registration of the declaration then creates units under construction, which can be transferred and mortgaged. A developer can therefore sell and finance the project before completion.
When must an owners' association (SVJ) be formed?
In a building with at least five units, at least four of which belong to four different owners (Section 1198(1)). After that, the Land Register will not record the transfer of a further unit until the formation of the SVJ has been proven (Section 1198(2)). A developer, as the sole owner of all units, can set up the SVJ alone (Section 1200(1)).
Who arranges the measurement survey and floor plans?
Our partner surveying firm. We coordinate the survey and check the floor plans against the declaration. If you have your own surveyor or designer, we are happy to work with them.
What if there is an error in the declaration?
A defect in the definition of a unit must be remedied without undue delay by the person who made the declaration, as soon as a person with a legal interest draws their attention to it. If they fail to do so, the owners of the affected units can remedy it by a joint declaration; otherwise, the court decides (Section 1168(1)). Once units have been sold, a correction is slow and expensive, so it pays to get the declaration right the first time.
How much does it cost to divide a building into units?
The price depends on the number of units, maisonettes, exclusive use of common parts, easements and whether we also set up the SVJ. Once you have filled in the form, we send a quote within 1 business day.
