Building legalisation and cadastre registration in Croatia: a guide for owners
Legalisation has reopened in Croatia. How it differs from registering a building in the cadastre and land register, and what you need for a sale or mortgage.
The house you have lived in for decades, the garage your grandfather built, the shed in the yard — they exist on the ground, but often not in the public registers. The problem usually surfaces at the worst possible moment: during a sale, an inheritance, or when the bank asks for documents for a mortgage.
This guide explains two procedures that are constantly confused in Croatia — legalisation and registering a building in the cadastre and land register — and how to sort them out without going from counter to counter.
Two procedures, one goal
| Procedure | What it solves | Who decides |
|---|---|---|
| Legalisation | The building’s legality (decision on the as-built state) | Building-permit authority |
| Registration with a survey report | The building is drawn on the cadastral plan and entered in the land register | Cadastre and land-register court — in a single procedure |
In other words: legality is a building-law question, while registration is a register question. The survey report (geodetski elaborat) links the cadastre and the land register into one whole — once it is implemented, the cadastral and land-register records are automatically aligned. A building can be legal but unregistered — or registered but not legal.
Legalisation has reopened
The Act on Procedures with Illegally Constructed Buildings allowed legalisation of buildings visible on the State Geodetic Administration’s digital orthophoto map based on aerial imaging started on 21 June 2011. The original application deadline expired long ago — but amendments adopted this year have reopened legalisation, under the same conditions as before.
What does that mean today?
- If your building is visible on the 2011 orthophoto map and you never applied, you can now apply.
- If an application was already filed but the procedure was not completed, it can be completed — often what is missing is the as-built survey or supplementary documents.
- If the building is newer, the route is the regular procedure under current building and planning law — with design documents and a building act.
Every case is specific. Before paying for any survey report, check which route is realistic for your building.
Registration in the cadastre and land register — one procedure
A building is registered on the basis of a survey report prepared by a licensed surveyor from a field survey. The cadastre reviews and certifies the report, and its implementation draws the building on the cadastral plan and enters it in the land register at the same time (area, use, house number). These are not two separate procedures.
The acts that prove a building is legal are:
- a use permit,
- a decision on the as-built state (legalisation).
A building can be registered even without an act of legality — but the land register then notes that no such act was submitted. The building is registered and visible in the registers, but not legal, and a buyer, notary or bank will see that immediately.
Why it matters for mortgages and sales
Banks generally require a property used as collateral to be both legal and registered. Without legality, a building is generally difficult or impossible to connect to utilities or enter into subsidy and funding programmes. Buyers and agencies increasingly check the same — mismatches between the cadastre, the land register and the situation on the ground are among the most common reasons for stalled sales.
How the process works with us
- Assessment — we review the available documents and the cadastre and land-register data.
- Advice — we tell you which route is realistic for your building and how long it will take.
- Field survey — measured with GNSS RTK equipment and a total station.
- Survey report — prepared according to State Geodetic Administration rules.
- Implementation — the cadastre reviews and certifies the report, and changes are implemented in the cadastre and land register.
Mistakes we see most often
- Buying a property without comparing the site with the cadastral plan.
- Believing a building is “registered” because it is visible on the Geoportal (an orthophoto is not registration!).
- Believing a registered building is automatically a legal one.
- Waiting to sort out the paperwork “when it’s needed” — when time is shortest.
