Subdivision of Property (Condominium Conversion) – Procedure, Costs and Timeframes (2026 Guide)

26/03/2026

Intro

Subdivision of property (condominium conversion) is a legal process by which a single property is divided into individual units (apartments, business premises, garages) that can be independently registered in the land registry. Without this process, it is not possible to legally sell or encumber a specific unit as a separate property.

Below is a detailed guide to the procedure, costs and expected timeframes.

What is property subdivision (condominium conversion)?

This process determines:

which parts of the building are individual units (apartments, business premises)
which parts are common areas (hallways, roof, installations)
ownership shares linked to each unit

After the process is completed, each unit receives:

its own title deed
the ability to be sold, gifted or mortgaged

When is subdivision necessary?

Subdivision is required in the following situations:

purchase of an apartment in a non-subdivided building
division of co-ownership between owners
regulation of legal relations between co-owners
sale of a specific part of the property

Without subdivision, the buyer does not become the owner of a specific apartment, but only a co-owner of the entire property.

Subdivision procedure – step by step

1. Collecting documentation

Required documents include:

title deed (land registry extract)
cadastral plan
occupancy permit (or other proof of legality)

2. Preparation of the subdivision study

A licensed surveyor prepares a subdivision study which includes:

description of all individual units
surface areas of each unit
floor plans and layouts

3. Co-owners’ agreement

All co-owners must agree on:

the division of the property
allocation of individual units
ownership shares

This is often the most challenging part of the process.

4. Registration in the land registry

After the study and agreements are completed:

a proposal is submitted to the court
the court registers the subdivision
separate title deeds are created for each unit

How much does property subdivision cost?

The cost depends on the size and complexity of the property.

Estimated costs:

surveying study: €500 – €2,000
legal services / attorney: €300 – €1,000
court fees: €100 – €300

Total: approx. €1,000 – €3,000

How long does the process take?

The timeframe depends on several factors:

preparation of the study: 2 – 6 weeks
agreement between co-owners (often the longest stage)
court registration: 1 – 3 months

Total duration: 1 to 6 months

Common issues in practice

The most frequent problems include:

disputes between co-owners
inconsistencies between cadastral and land registry data
illegal or unregistered parts of the building
missing documentation

In such cases, the process may take significantly longer.

Is subdivision possible without consent of all co-owners?

As a rule – no.

However, it is possible to:

initiate court proceedings for termination of co-ownership
seek a court decision instead of consent

This is a complex legal procedure and requires professional assistance.
