Land and Mortgage Register in Poland: How to Check a Property and Not Lose Money
Buying an apartment, house, or land in Poland is a serious financial decision.
That is why, before signing a preliminary agreement or a notarial deed, it is important to check not only the price, location, and condition of the property, but also its legal status.
The key document for such verification is the land and mortgage register (Księga wieczysta, KW).
It shows:
• who owns the property
• whether there is a mortgage
• whether there are any restrictions
• whether there are third-party rights
• whether there are risks that may affect the transaction
For a buyer, the KW is not a formality.
It is the main source of information that helps identify risks in advance and avoid costly mistakes.
What is the land and mortgage register
The land and mortgage register (Księga wieczysta, KW) is an official public register that reflects the legal status of real estate in Poland.
It allows you to check:
• who the owner is
• whether there are co-owners
• whether any restrictions are registered
• whether there is a mortgage
• whether there are third-party rights
• whether there are legal claims or disputes
Important:
The KW is not a cadastral record and not a technical description of the property.
It is a register of rights, not of physical characteristics.
Why the KW is so important before purchase
Even if a property looks perfect, without checking the KW it is impossible to know:
• whether the seller actually has the right to sell the property
• whether there are hidden legal issues
• whether third-party rights will remain after purchase
• whether the property may involve disputes, restrictions, or additional costs
A common mistake buyers make is viewing the property as a client, not as a future owner.
The KW shows the real legal situation, not just a “nice picture”.
Structure of the land and mortgage register
The land and mortgage register consists of four main sections:
Section I-O – Property designation
→ address, area, plot number, description
Section I-Sp – Rights related to ownership
→ e.g. right of way or access
Section II – Ownership
→ who owns the property
Section III – Rights, claims and restrictions
→ the most important section from a risk perspective
Section IV – Mortgage
→ loans and encumbrances

The role of the notary
The notary:
• verifies documents
• formalizes the transaction
• works with KW data
However, it is important to understand:
the notary does not replace a full independent property check.

Conclusion
The land and mortgage register (Księga wieczysta, KW) is the key tool for transaction safety in Poland.
It shows not the appearance of the property, but its legal reality:
who owns it, whether there are restrictions, mortgages, or third-party rights.
The more carefully you check the KW before the transaction, the safer your purchase will be.
