Apartment or House Condominium - Legal Guide and Common Owner Mistakes
11/10/2025
What is condominium (etažiranje) and why is it important?
Condominium establishment, known in Croatian as etažiranje, is a legal process by which each apartment, house, or business unit is registered in the land registry as a separate property. Without it, owners cannot clearly prove ownership, which complicates selling, gifting, inheritance, or obtaining a mortgage. This process is regulated by the Ownership and Other Real Rights Act and is essential whenever several people own shares in the same building or land parcel.
What does condominium registration achieve?
- Each apartment or business unit becomes a legally separate property.
- The owner receives an individual land registry extract.
- Establishes clear co-ownership shares in common parts such as the roof, stairs, or façade.
- Enables lawful management and transactions — sale, gift, inheritance, mortgage, or rental.
In practice, condominium registration transforms shared ownership into clearly defined individual ownership and protects owners from potential disputes.
Steps of the condominium process
1) Preparation of the geodetic survey (condominium plan)
This plan is prepared by a licensed surveyor and includes detailed floor plans, area measurements, designations of each unit, and a list of common parts with corresponding co-ownership shares.
2) Co-ownership agreementAll co-owners sign an agreement defining which parts are private and which are common, how maintenance costs are shared, and how the property is managed.
3) Registration in the land registryOnce documentation is complete, the lawyer submits a registration proposal to the land registry. Upon approval, each owner receives an individual ownership certificate (land registry extract) for their unit.
Required documentation
- Land registry extract / proof of ownership
- Occupancy permit or other proof of legal construction
- Cadastral plan and property map
- ID copies of owners
- Geodetic survey and co-ownership agreement
Tip: Ensure that the actual physical condition matches the construction documents (floor plans, unit size). Mismatches are a common reason for land registry rejections.
Common mistakes made by owners
- Incomplete documentation – missing occupancy permits or unsynchronized cadastral data.
- Discrepancies between floor plans and real condition.
- Lack of consent or misunderstanding among co-owners.
- Incorrect co-ownership share calculation.
- Improperly drafted registration proposal for the land registry.
These errors often lead to rejected applications and additional costs. Professional legal assistance ensures a smooth and lawful process.
Why hire a lawyer for condominium establishment?
