A Polish counterparty offers a mortgage (hipoteka) as security. Before accepting that pledge, a foreign buyer or lender needs to establish two things: what the asset is actually worth, and what already encumbers it. Both questions are answerable from official registers — with known limits.
- Primary register
- Księgi Wieczyste (Land and Mortgage Register) — maintained by the Ministry of Justice at ekw.ms.gov.pl. Publicly searchable by KW number. Verified: July 2026.
- What it shows
- Current ownership, legal description, all registered mortgages and encumbrances, pending proceedings. Each entry is timestamped.
- Access condition
- KW number required. Without it, the register cannot be searched by address or owner name through the public portal.
- What it does not show
- Unregistered claims, tax arrears not yet entered, court-ordered interim injunctions that have not yet been noted in the register.
What the Land and Mortgage Register actually contains
The Księgi Wieczyste system divides each property record into four sections. Section I describes the property: cadastral parcel number, area, permitted use. Section II records the owner or co-owners with their shares. Section III lists encumbrances other than mortgages — easements, rights of pre-emption, interim injunctions, pending expropriation proceedings. Section IV lists all mortgages: creditor, amount, currency, rank, and whether the mortgage is ordinary (zwykła) or ceiling-type (kaucyjna).
Rank matters. Polish law follows the principle of priority by date of entry. A later-ranking mortgage is repaid only after all higher-ranking mortgages are satisfied. The register shows rank explicitly. A property with a first-ranking mortgage at a high loan-to-value ratio leaves little or no residual collateral value for a second-ranking lender.
| Section | Content | Collateral relevance |
|---|---|---|
| I | Property description, parcel ID, area, permitted use | Establishes what asset is actually being pledged |
| II | Owner(s), shares, basis of acquisition | Confirms the pledgor has title to give |
| III | Non-mortgage encumbrances, easements, injunctions | Identifies restrictions on use or transfer |
| IV | All mortgages: creditor, amount, currency, rank | Determines residual security value after prior claims |
The KW number problem
The public portal at ekw.ms.gov.pl is searchable only by KW number. There is no name search and no address search available to a member of the public. A counterparty that declines to provide the KW number is, in effect, blocking register access. This is not a technical limitation — it is a deliberate access structure.
The KW number can be obtained from the notarial deed of acquisition, from the cadastral authority (Starostwo Powiatowe) by reference to the parcel number, or from the court registry. Each route requires a Polish-language request and, in some cases, a declaration of legitimate interest. Without the number, no collateral verification is possible through the public portal.
Cadastral register: a parallel check
The Ewidencja Gruntów i Budynków (EGiB) — the cadastral register — is maintained by Starostwa Powiatowe (district offices) and partially accessible through the Geoportal at geoportal.gov.pl. It records parcel boundaries, area, land classification, and building footprints. It does not record ownership or encumbrances.
Cross-referencing the KW entry against the cadastral record confirms whether the parcel described in Section I of the KW actually matches the physical asset. Discrepancies in area or classification between the two registers are a known issue in Polish real estate. They arise from historical surveying gaps and from land consolidation proceedings not yet reflected in both systems.
| Question | KW (ekw.ms.gov.pl) | Cadastre (EGiB / geoportal.gov.pl) |
|---|---|---|
| Who owns the asset? | Yes | No |
| What mortgages are registered? | Yes | No |
| What is the parcel boundary and area? | Partially (description only) | Yes |
| What is the land classification? | Partially | Yes |
| Are there pending expropriation proceedings? | Sometimes (if noted) | No |
| Is the building lawfully constructed? | No | No — separate building permit register |
Building permit and occupancy status
The KW register and the cadastral register do not confirm whether a building was constructed with a valid permit or whether an occupancy permit (pozwolenie na użytkowanie) was issued. This information is held by Powiatowe Inspektoraty Nadzoru Budowlanego (district building supervision offices) and, for some proceedings, by the Główny Urząd Nadzoru Budowlanego (GUNB) national register accessible at wyszukiwarka.gunb.gov.pl.
A building without an occupancy permit cannot be legally used. For a lender, this creates enforcement risk: the asset on paper may not correspond to the asset that can be sold or leased. The GUNB portal covers decisions issued in electronic form from a certain date onward; older paper records require a request to the district office.
Insolvency and restructuring proceedings
The Krajowy Rejestr Zadłużonych (KRZ) — National Debtors Register — is the central Polish register for insolvency, restructuring, and debt enforcement proceedings. It is accessible at krz.ms.gov.pl. An entity subject to insolvency proceedings may have its ability to encumber or transfer assets restricted or nullified.
A negative result in the KRZ does not guarantee that no application has been filed. Applications are entered after a court order, not at the point of filing. There is a gap between submission and registration. For time-sensitive transactions, the filing date at the relevant court — not the KRZ entry date — is the operative reference.
Registered pledges on movable assets
Where the collateral offered includes movable assets — machinery, equipment, inventory, receivables — the relevant register is the Rejestr Zastawów (Pledge Register), maintained by the Ministry of Justice and searchable at rejestrzastawow.ms.gov.pl. A registered pledge (zastaw rejestrowy) on a movable asset grants the pledgee priority over unsecured creditors and, under certain conditions, the right to take possession without court proceedings.
The register is searchable by the name or PESEL/NIP of the pledgor and by the pledge subject. Pledges not entered in this register do not have registered-pledge status, though ordinary civil-law pledges may still exist outside the register.
Tax arrears and administrative charges
Polish tax authorities (Urząd Skarbowy) and local government units may hold claims against a property owner that have not yet been entered in the KW register. Under Polish law, certain public-law claims have statutory priority in enforcement regardless of registration. A clean KW Section IV does not exclude the existence of such claims.
A certificate of no tax arrears (zaświadczenie o niezaleganiu w podatkach) can be requested from the competent tax office. The request must be made by or with the consent of the taxpayer. This is a procedural barrier for a third-party lender acting without the counterparty's cooperation.
Spatial planning and permitted use
The value of a Polish property is directly linked to what can lawfully be built or operated on it. Local spatial development plans (miejscowe plany zagospodarowania przestrzennego, MPZP) are adopted by municipal councils and published in local official journals. They are accessible through municipal GIS portals and, partially, through the national geoportal. Where no MPZP exists, development decisions (decyzje o warunkach zabudowy) govern individual plots.
A change in MPZP classification — for example, from commercial to green-belt — can substantially reduce a property's market value. Pending plan amendments are not visible in the KW register. They appear in municipal planning registers and council resolutions.
The limit of what the sources allow
The KW register shows what has been entered. It does not show what is pending entry, what was never filed, or what exists in a parallel administrative track. Specifically: an interim court injunction freezing the asset may be issued but not yet noted in Section III. An insolvency application may be filed but not yet visible in the KRZ. A tax lien may exist without KW entry. A building may be registered in the cadastre but lack a lawful occupancy permit.
The chain of sources — KW, EGiB, KRZ, Rejestr Zastawów, GUNB, MPZP — covers the principal risk layers. It does not cover private contractual encumbrances (options, pre-emption rights in private agreements), claims under ongoing litigation not yet reduced to a registered measure, or environmental liabilities not reflected in administrative registers. Each of these is a known gap, named here before any engagement, not after.
Where the KW number is not provided, register access through the public portal is not possible. Obtaining the number through cadastral or court channels requires Polish-language requests, national identifiers, and in some cases a declaration of legitimate interest. This removed path is the operative obstacle for a foreign principal acting without local assistance.
Where the sources disagree
Area discrepancies between KW Section I and the EGiB cadastral record are frequent. The KW may show the area as recorded at the time of initial registration; the cadastre may show a corrected figure following a later survey. For financing purposes, the operative area is the cadastral figure — but the KW mortgage attaches to the legally described parcel, which may differ.
Ownership discrepancies also occur. The KW records the owner as registered. The cadastral authority may show a different name if a transfer was recorded in the cadastre but the KW was not updated — or vice versa. Polish law treats the KW as the authoritative source for ownership and encumbrances, but a discrepancy between the two registers is itself a material finding that requires explanation before any security is accepted.
The verification sequence
The following sequence reflects the order in which each check informs the next. Skipping steps or reversing the order produces an incomplete picture.
| Step | Register / source | What it establishes | Precondition |
|---|---|---|---|
| 1 | KW — ekw.ms.gov.pl | Owner, all mortgages and encumbrances, rank | KW number required |
| 2 | EGiB / geoportal.gov.pl | Parcel boundary, area, land classification | Parcel number (from KW or cadastre) |
| 3 | KRZ — krz.ms.gov.pl | Insolvency or restructuring proceedings against owner | Owner name and NIP/PESEL |
| 4 | GUNB — wyszukiwarka.gunb.gov.pl | Building permit and occupancy permit status | Address or decision number |
| 5 | Rejestr Zastawów — rejestrzastawow.ms.gov.pl | Registered pledges on movable assets (if included) | Pledgor name and NIP/PESEL |
| 6 | Municipal MPZP / GIS portal | Permitted use, pending plan amendments | Parcel number and municipality |
| 7 | Tax office (with counterparty cooperation) | Certificate of no tax arrears | Counterparty consent or power of attorney |
What a counterparty's refusal signals
A counterparty that declines to provide the KW number, the NIP, or the cadastral parcel reference is preventing verification — not delaying it. Each of these identifiers is a matter of public record once the register is accessed. Withholding them does not protect privacy; it blocks the access path.
Cooperation with verification is itself a signal. A counterparty offering mortgage security and refusing to support basic register checks is exhibiting behaviour inconsistent with a clean asset. This observation does not constitute a legal characterisation of that refusal.
Frequently asked questions
Can the KW register be searched by address or owner name?
The public portal at ekw.ms.gov.pl does not offer name-based or address-based search. Search requires the KW number. Obtaining the KW number without counterparty cooperation requires a request to the cadastral authority or the relevant court registry, with the parcel number as the starting point.
Does a clean KW Section IV mean the property is unencumbered?
No. Section IV shows registered mortgages. It does not show unregistered contractual encumbrances, tax claims not yet entered, or interim injunctions that have been issued but not yet noted. A clean Section IV is a necessary starting point, not a sufficient conclusion.
What is the difference between an ordinary mortgage and a ceiling mortgage in Polish law?
An ordinary mortgage (hipoteka zwykła) secures a defined, existing claim. A ceiling mortgage (hipoteka kaucyjna) secures claims up to a stated maximum, including future or contingent claims. The ceiling type is now the standard form under Polish law following the 2011 amendment. The register entry specifies which type applies and the maximum amount.
This page describes what the register shows. It does not characterise the legal effect of either type for a particular transaction.
Is the KW register free of charge?
The public viewing portal at ekw.ms.gov.pl is publicly accessible and free of charge for viewing current entries. Certified extracts (odpisy) are issued by court registry departments and carry a fee set by the Ministry of Justice tariff. What a verification service provides is the removed path: obtaining the KW number, reading Polish-language entries, cross-referencing across multiple registers, and producing a structured English-language report.
How current is the KW register?
Entries are made by court registry clerks following receipt of documents. There is no statutory maximum delay between an event (for example, a mortgage agreement) and its entry in the register. In practice, delays of weeks to months occur. Priority is determined by the date of the application for entry, not the date of the underlying agreement — but only once the entry is made.
