Księgi Wieczyste is Poland's land and mortgage register. It records ownership, encumbrances, and third-party rights on every registered property. A foreign buyer or lender checking Polish commercial real estate as collateral starts here — but the register has structural limits that determine how much it can confirm.
- What it shows
- Current owner, legal basis of acquisition, mortgage entries (hipoteka), easements, and third-party claims. Source: Elektroniczne Księgi Wieczyste (EKW) · verified June 2026.
- Access condition
- Search requires the KW number. Name-based search is not available to private parties. Path: land parcel register (ewidencja gruntów) → KW number → EKW entry.
- Cost
- Free of charge. EKW is a public, open register. What a verification report provides is the removed path: locating the KW number, cross-referencing encumbrance registers, and producing a structured English-language output.
- What it does not show
- Fiscal pledges (zastawy skarbowe), pledges on movables registered under the Civil Pledge Register (Rejestr Zastawów), and insolvency proceedings are held in separate registers. A clean KW entry does not confirm a clean collateral profile.
What Księgi Wieczyste records and what it omits
The KW register is divided into four sections. Section I identifies the property and its area. Section II records the owner or perpetual usufructuary. Section III lists encumbrances other than mortgages — easements, pre-emption rights, and similar claims. Section IV records mortgage entries (hipoteki), including the creditor, amount, currency, and ranking.
Each section is current as of the last court entry. Polish land registry courts process entries sequentially. A mortgage applied for but not yet entered appears in the application queue, not in the printed register. The queue (dziennik ksiąg wieczystych) is visible in EKW but requires a separate reading step.
The register does not record: fiscal pledges (zastawy skarbowe) created by tax authorities, pledges on movables registered in the Rejestr Zastawów, enforcement proceedings initiated by bailiffs, or insolvency proceedings. Each of those requires a separate query to a separate register.
The two pledge registers that run parallel to KW
Polish law maintains two distinct pledge registers. Both are separate from Księgi Wieczyste and neither is visible in an EKW search.
The Rejestr Zastawów (Ministry of Justice, Centralna Informacja) covers registered pledges on movables and rights. A certificate on a pledgor (DW-1) costs 20 zł. A certificate on a specific collateral item (DW-2) costs 20 zł. A certified extract (DW-4) costs 15 zł per item.
The Rejestr Zastawów Skarbowych (Ministry of Finance) covers fiscal pledges created by tax authorities in favour of the State Treasury. Search by collateral item is free. A certified statement (wypis/zaświadczenie) costs 50 zł and is available through e-Urząd Skarbowy.
A complete encumbrance check for Polish commercial property requires all three registers: EKW, Rejestr Zastawów, and Rejestr Zastawów Skarbowych. Checking only KW is standard practice in domestic transactions but insufficient for cross-border collateral assessment.
Owner identity and corporate structure
If the registered owner is a legal entity, KRS (Krajowy Rejestr Sądowy) provides the corporate record. KRS is free of charge. It shows the entity's legal form, registered address, management board, supervisory board, and share capital. Certified extracts (odpis) are available at a fee in the range of 30–60 PLN.
CRBR (Centralny Rejestr Beneficjentów Rzeczywistych) is Poland's beneficial ownership register. It is open, free, and requires no account. It records natural persons who ultimately own or control the entity. CRBR entries are self-reported by the entity; the register does not independently verify the information submitted.
VAT status and registered bank accounts are checked through the Biała Lista (White List of VAT Taxpayers), maintained by the Head of KAS. The register is free, requires no login, and allows historical queries on any past date. It shows VAT status, registered addresses, and bank account numbers declared to the tax authority.
Insolvency status of the seller or borrower
KRZ (Krajowy Rejestr Zadłużonych) is Poland's insolvency and restructuring register. It is public, free, and requires no login. Search is by PESEL, NIP, KRS number, or case signature. It covers bankruptcy, restructuring, and debt relief proceedings.
KRZ contains only proceedings opened after 1 December 2021. Proceedings initiated before that date were recorded in MSiG (Monitor Sądowy i Gospodarczy) and in the predecessor register RDN. A negative KRZ result does not exclude an earlier insolvency. Verification of the full insolvency history requires a cross-check of MSiG, which is searchable free of charge at wyszukiwarka-msig.ms.gov.pl with archive coverage from 1996.
Insolvency proceedings opened after December 2021 are published in KRZ, not in MSiG. The two systems do not overlap; they are sequential.
Financial statements of the property-owning entity
Polish companies subject to the Accountancy Act file annual financial statements with KRS. These are stored in the Repozytorium Dokumentów Finansowych (RDF) and are free to access. The repository contains balance sheets, profit and loss accounts, and auditor reports where applicable.
Not all Polish entities are required to file with RDF. Sole traders and civil law partnerships (spółki cywilne) do not file in KRS. For those structures, financial data is not publicly available.
The limit of what the sources allow
Księgi Wieczyste confirms what is entered. It does not confirm what is pending entry. The application queue must be read separately from the register itself. A mortgage signed but not yet entered by the registry court is not visible in the standard EKW output — it appears only in the queue log.
No single register covers the full encumbrance profile of a Polish property. EKW covers mortgages and Section III rights. Rejestr Zastawów covers registered pledges on movables and rights. Rejestr Zastawów Skarbowych covers fiscal pledges. Bailiff enforcement proceedings are recorded at individual district court enforcement divisions and are not consolidated in a national searchable database accessible to third parties. That gap is structural and cannot be closed through register queries alone.
CRBR beneficial ownership data is self-reported. The register records what the entity declared. It does not independently verify the chain of control. Where the declared beneficial owner differs from the chain visible in corporate documents, the discrepancy itself is a finding — not a resolution.
Where the sources disagree
KW Section II shows the current registered owner. KRS shows the entity's current registered address and management. CRBR shows the declared beneficial owner. These three records are maintained independently and updated on different timelines. Where they conflict — for example, a KW entry naming an entity that no longer exists in KRS in the same form — the conflict is a material finding that requires document-level review, not a further register query.
RDF financial statements reflect the position as of the filing date. They are historical. A property-owning entity with clean financials at the last filing date may carry undisclosed liabilities that post-date the filed accounts. The register does not flag that gap; it only shows what was filed.

Frequently asked questions
Can the KW number be found without the seller's cooperation?
Yes, in most cases. The path runs through ewidencja gruntów i budynków (land parcel register), which links cadastral parcel numbers to KW numbers. The parcel number is typically visible in planning documents, the notarial deed, or cadastral maps. Where those documents are not available, the path requires the address and municipality identifier, which allows a starostwo (district authority) query.
Does a clean KW entry mean the property is unencumbered?
No. A clean KW Section IV means no mortgage is entered. It does not exclude fiscal pledges (Rejestr Zastawów Skarbowych), registered pledges on movables or rights (Rejestr Zastawów), or enforcement proceedings at district court level. Those require separate queries. Standard and Extended tiers cover the pledge registers.
Is the beneficial ownership register (CRBR) reliable for collateral purposes?
CRBR data is self-reported by the entity. The register is open and free. It records the declared beneficial owner as of the last filing. It does not verify the underlying corporate chain. Where the declared beneficial owner and the chain visible in KRS corporate documents diverge, that divergence is the finding — not a data error to be disregarded.
How far back does the insolvency search go?
KRZ covers proceedings from 1 December 2021 forward. MSiG covers announcements from 1996 forward. Proceedings between those dates that were not published in MSiG — or that pre-date 1996 — are not accessible through national searchable databases. The Extended tier includes a full MSiG archive search for all entities in the ownership chain.
What is the delivery timeline?
Signal and Standard tiers: 3 business days from confirmation of the KW number and entity identifiers. Extended tier: 5 business days. Timeline starts on the business day following receipt of identifiers and payment confirmation.
