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

How to read the KW before purchase

The check should be done step by step:

1. Verify the property
   (address, area, description)
2. Verify the owner
   (whether it matches the seller)
3. Check restrictions
   (especially Section III)
4. Check the mortgage
   (and how it will be settled)

Important:
Do not skim through the KW.
Sometimes a single entry can completely change the nature of the transaction.

What to pay special attention to

Particular caution is required in cases of:

• mismatch of the owner
• multiple owners
• enforcement proceedings
• property seizure
• lifetime residence rights
• personal easements
• restrictions on disposal
• legal claims and disputes
• wzmianka (a note about a pending application)

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.

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.
