Parcel change (split, merger)

A split, merger, new survey or change of land type recorded for a parcel. Not a sale, but many changes in one place may signal new development.

A parcel change means splitting a plot, merging plots, changing or refining a boundary, changing the land type or land use, and similar changes to how the plot is recorded in the land register. Boundary changes are based on a survey plan (Section 79 of Decree No. 357/2013 Coll.). A change of land type is supported by a document from the relevant authority, for example consent from the agricultural land fund protection authority.

How a change happens

Splitting or merging plots may require a permit from the building authority (Sections 216 and 217 of the Building Act No. 283/2021 Coll.). The land register then requires this document as an attachment to the application for registration (Section 15 of the Cadastral Act). A survey plan on its own changes nothing; the change happens only when the deed it belongs to is registered.

Changes not arising from documents that authorities send to the register themselves must be reported by the owner to the cadastral office within 30 days and supported by a document, for example a change of land type or the demolition of a building (Section 37 of the Cadastral Act).

How to read it

In the RÚIAN register every parcel has a date from which its current form is valid and an identifier of the land register proceeding. Since 12 January 2022 parcels have been transferred to RÚIAN from the land register information system continuously. From this you can see how many parcels nearby changed in recent months and in how many proceedings.

A parcel change is not a sale. RÚIAN does not record owners, so a sale does not show up in this data. Several new parcels in one place may mean subdivision for family houses, a new road or land consolidation.

Frequently asked questions

Does a new parcel mean it can be built on?

No. What may be built on a plot is determined by the zoning plan and the building authority's permit. A parcel change on its own permits nothing.

Do parcel numbers change when a plot is split?

A split creates new parcels, and at least some of them get new parcel numbers. The numbering is approved by the cadastral office, which confirms a survey plan precisely by approving the parcel numbering (Section 48 of the Cadastral Act).
