Land and Mortgage Register
A public register maintained by Polish district courts that records the legal status of a property — its owner, boundaries, and any mortgages, liens, or easements attached to it.
Applies to Poland.
Definition
The Land and Mortgage Register (księga wieczysta, abbreviated KW) is a public, court-maintained record of the legal status of a specific piece of real estate in Poland. Every register is split into four numbered sections:
- Section I — description of the property (location, area, purpose)
- Section II — ownership and co-ownership shares
- Section III — limited property rights and claims other than mortgages (e.g. easements, right of way, life tenancy)
- Section IV — mortgages secured against the property
Since 2003 all registers have been progressively migrated to an electronic system, and today the full content of almost every register can be viewed free of charge online through the Ministry of Justice's Elektroniczne Księgi Wieczyste portal by entering the register number.
The single most important legal feature of the register is the rękojmia wiary publicznej ksiąg wieczystych — the principle of public reliance. In short, the law presumes that what is entered in the register reflects the true legal state of the property, and a buyer who relies in good faith on that entry is protected even if the register later turns out to have been inaccurate.
Examples
Before signing a preliminary agreement, a buyer's lawyer pulls the register by its number and confirms that Section II lists the seller as sole owner, and that Section IV shows no outstanding mortgage.
A property advertised as "free of encumbrances" turns out to have a right-of-way entry in Section III — the buyer negotiates a price reduction once this is discovered in the register.
How this affects buying and selling
Checking the register before making an offer is the single most effective way to avoid buying a property with hidden debts or disputed ownership — a mortgage or claim entered in Sections III or IV binds the property regardless of who currently occupies it. Sellers benefit from keeping their register current too: an outdated or inaccurate entry (for example, a mortgage that was already repaid but never formally removed) routinely delays closing while the entry is corrected at the court.
