The ideal part in the world of real estate: What exactly is it and how does it affect buying and selling?

In the world of real estate, we often encounter the term "ideal part," but many buyers and sellers are unsure what it exactly means, how it functions, and how it affects the buying or selling process. Understanding this legal concept is crucial for safe and successful management of real estate in co-ownership. In this guide, we explain what an ideal part is, how it can be bought or sold, and how to properly register co-ownership in land registers.

What is an ideal part?



An ideal part represents a legal share of ownership in a common property that is not physically separated. In other words, a co-owner owns a certain percentage of the property (e.g., 1/2 or 1/3), but does not own a specific space within the building. This term is crucial in situations where multiple people share ownership of the same property, such as family houses, residential buildings or commercial properties in co-ownership. The ideal part defines the rights and obligations of the co-owners and the manner of disposal of the property.

How is an ideal part bought and sold?



An ideal part can significantly affect the market value of a property. Properties in co-ownership often have a lower price due to limited disposal rights and possible conflicts among co-owners. Buyers are more cautious when entering into such transactions, which can reduce demand and thus the value of the property.
However, with proper management and agreement among co-owners, the value of the property can remain stable or even increase. The key to success is transparent communication, clear agreements and respect for the rights of all parties involved. A buyer who acquires an ideal part becomes a co-owner of the entire property, which means that he must respect the rights of other co-owners. Independent disposal of the entire property is not possible.

Can an ideal part be sold without the consent of the other co-owners?



Although it is technically possible to sell an ideal part without the consent of the other co-owners, such a transaction can lead to complications. The new owner enters into a co-ownership relationship with the existing co-owners, where decisions on the use and maintenance of the property are made jointly. In case of disagreements, the termination of the co-ownership community can be initiated, which is a legal procedure that can be lengthy and expensive.

How to properly register co-ownership in land registers?



Registration of co-ownership in land registers is crucial for the legal security of the owner of the ideal part. It officially confirms ownership of a specific share and prevents legal disputes during the sale, inheritance or disposal of the share.


Required documentation:


Purchase agreement – certified by a notary public.
Gift agreement – if the co-ownership was acquired by donation.
Inheritance decision – for shares obtained by inheritance.
Consent of other co-owners – although not mandatory, it is recommended to avoid future disagreements.
Proposal for registration in land registers – submitted to the competent land registry court.
Confirmation of paid court fees – the costs depend on the value of the share.

Registration procedure



Collection of documentation – check that all documents are correct.
Drafting a proposal for registration – it can be drafted by a lawyer, a notary public or the co-owner himself.
Submission of the application – in person, by mail or electronically via e-Citizens.
Processing of the application and registration – the court checks the documentation and makes a decision on registration.
Taking over the extract from the land registers – official proof of ownership.


Most common problems with buying



Unresolved property-legal relations of the previous owner.
Non-compliance of data between the contract and the cadastre.
Disagreements among co-owners about registration.


It is advised to consult with a lawyer or real estate expert in order for the procedure to be carried out without any problems.



The ideal part is an important legal concept in the world of real estate, which marks the share of ownership in a common property. Understanding its legal and market implications is crucial for buyers and sellers. Proper management, transparent communication among co-owners and proper registration in land registers guarantee a safe and successful transaction.
