15 red flags when buying
property in Warsaw.

Experienced due diligence distinguishes between a missing document, a legal inconsistency and a transaction-control failure. Missing evidence can often be supplied. An inconsistency may require a court entry, creditor document, spouse confirmation or redesigned contract. A payment-control failure is more urgent because money can leave the buyer before the underlying risk is resolved.

The official Electronic Land and Mortgage Register portal allows a buyer who knows the register number to inspect the content. The current Act explains the core structure. Section I describes the property and rights connected with ownership. Section II identifies ownership or perpetual usufruct. Section III records rights, restrictions, claims and warnings other than mortgages. Section IV contains mortgages.

The register benefits from statutory presumptions and, in defined circumstances, public-faith protection. That protection has limits. A person acting in bad faith is not protected, and Article 8 gives special significance to a notation of an application, appeal, cassation complaint or warning of inconsistency. That is why a buyer must inspect not only the owner name and mortgage balance but also every notation and pending matter visible on the day of signing.

Authority review begins with the owner shown in the register or the holder of the relevant cooperative right, but it does not end there. The acquisition history, marital-property position, inheritance chain, corporate representation and any power of attorney can affect who must appear or consent.

For a company seller or developer, the official KRS search provides current and full registry information. Match the company name, KRS number and representation rules to the people signing. For a private seller, compare identity data with title documents and clarify whether the property forms part of personal or marital common property. Article 37 of the Family and Guardianship Code makes spouse consent relevant to specified transactions involving common real estate. It does not mean that every married seller automatically needs a second signature; the property regime and acquisition history matter.

Remote or represented sales require particular care. Under the Civil Code, a power of attorney must follow the special form required for the transaction, and an act outside authority may depend on later confirmation. A foreign document may also require notarisation, apostille or legalisation and sworn translation before it can be used in Poland.

A listing is a marketing description, not a legal inventory. A parking space may be a separate non-residential unit, a share with an exclusive-use arrangement, a connected right, a lease or only an informal allocation. A storage room can be part of the apartment, an appurtenant room, a separate unit or a common area assigned for use. A garden can be ownership, exclusive use of common land or a contractual arrangement. These differences affect transferability, financing, fees and, for some foreign buyers, the MSWiA permit analysis.

The same discipline applies to floor area and layout. Confirm which measurement controls the price, whether a developer can adjust the final area, and whether the actual apartment corresponds with the deed, register, inventory and available plan. A beautifully finished room does not become part of the acquired legal right merely because it is accessible from the apartment.

A reservation form can look simple while creating a meaningful payment obligation and a very short timetable. Before signing, identify who receives the money, whether the recipient owns or controls the property, what documents must be delivered, what happens if title or permit review fails, whether financing is a condition, and exactly when the amount is returned or retained.

Polish terminology matters. Zadatek and zaliczka do not have the same default consequences. Article 394 of the Civil Code provides a statutory framework for earnest money where the contract does not state otherwise, including consequences for non-performance. The contract can shape the outcome, so translating both words simply as “deposit” hides a material difference.

For transactions covered by the Developer Act, the developer must provide the prospectus and attachments before the developer agreement or a preceding reservation agreement. The Act caps the reservation fee at one percent of the apartment or house price stated in the prospectus and provides statutory refund rules in specified situations. That framework should not be copied blindly into an ordinary secondary-market transaction where a different legal basis applies.

Ask who lives in the apartment, on what basis and when they will leave. A tenant, family member, borrower or former partner may not be visible during a viewing. If a tenancy exists, inspect the full agreement, amendments, deposit, payment history and any termination notices. Under Article 678 of the Civil Code, a buyer generally enters the existing lease in place of the seller. The sale itself is therefore not a reliable vacant-possession strategy.

Administrative or cooperative certificates also matter. A certificate concerning charges and arrears is not the same thing as title, and seller debt does not automatically become buyer debt merely because the apartment is sold. Still, missing or inconsistent information may expose disputes, litigation, enforcement risk, unapproved works, unusually high charges or a seller who cannot complete the promised settlement. Review the applicable structure under the Act on Ownership of Premises or the Housing Cooperatives Act.

Not every moved internal wall is illegal and not every renovation requires a building permit. The correct question is what work was done, whether it affected structural elements, common property, fire safety, installations, ventilation, wet-room location or the use of the premises, and which approvals, notifications or consents applied. Compare the current layout with the available plan and ask for design, consent, notification or completion documents where the scope makes them relevant.

The current Building Law is the statutory starting point. The public GUNB RWDZ search can help identify building-permit applications, decisions and notifications, but its public dataset is not a complete historical file for every building and should not be treated as the sole proof that no issue exists. For the surrounding area, use the City of Warsaw architecture maps and local-plan portal to investigate adopted and developing planning documents.

The seller must also provide the energy performance certificate in the circumstances described by the official Ministry guidance. The certificate is not a technical inspection and does not prove that installations are sound. It is one document in a broader building review.

Buying from a developer replaces some resale risks with project and delivery risks. The Developer Act requires a developer beginning sales to prepare a prospectus, and the prospectus with attachments must be delivered free of charge on a durable medium before the developer agreement or a preceding reservation agreement. Read it together with the draft contracts, land register, building permit information, payment schedule and handover standard.

Do not treat the marketing brochure as the controlling specification. Check the developer entity in the official KRS, confirm who owns or controls the land, identify the housing escrow account, understand the Developer Guarantee Fund framework, and review what happens if the final area, completion date, materials or common areas change.

The statutory one-percent reservation-fee cap and refund protections apply within the covered developer framework. Their existence does not remove the need to review the reservation period, mortgage decision timetable, permit route, documents promised before the developer agreement and the treatment of separately priced parking or storage.

The official MSWiA guidance sets out the general permit framework and statutory exemptions for foreign purchasers. A self-contained residential unit outside a border zone may fall within an exemption, but separate land, a house, unusual ownership rights, a share connected with parking or another property component can change the analysis. United Kingdom buyers have been subject to the general post-Brexit framework since 1 January 2021 unless an exemption applies.

Resolve the permit route before accepting a contract deadline. If a permit is required, the transaction timetable and document package should reflect it. If an exemption is relied upon, record the property facts and legal basis supporting that conclusion. A sales agent statement that “foreigners never need a permit for apartments” is too broad to use as transaction advice.

Remote purchase adds a second control layer. A power of attorney for a real-estate deed must be prepared in the form required by Polish law. The Polish notary or lawyer should approve the exact text before it is signed abroad. Country-specific notarisation, apostille or legalisation, sworn translation, original delivery and bank compliance requirements can affect whether the planned signing date is realistic.

Before each transfer, match the recipient, bank account, amount, currency, value date and payment purpose to the signed transaction documents. Independently confirm any change in instructions through a trusted channel already known to the buyer. An email or instant message announcing a new account should never be the sole basis for moving the purchase price.

The payment sequence must also reflect legal risk. Where a mortgage is being repaid, part of the price may need to go directly to the creditor under current written instructions, with the remainder released to the seller under the deed. In other transactions, payment may occur before, during or after signing depending on the agreed protections. The safest answer is therefore transaction-specific rather than a universal instruction to pay one party at one moment.

Article 108 of the Notarial Law allows a notary, in connection with a notarial act, to accept money for delivery to the indicated person and record the deposit in a protocol. A notarial deposit can be useful where the agreed conditions fit that mechanism, but it is optional, must be arranged in advance and should not be described as mandatory for every purchase.

Polish real-estate transactions can involve a seller agent, buyer agent, listing portal, developer sales office, referral partner and legal or technical specialists. Their roles may overlap, but their incentives are not identical. Ask in writing who engaged the intermediary, whose interests they undertake to represent, who pays their remuneration, whether they receive referral fees and whether the property was selected from the full market or from a limited inventory.

A conflict is not automatically disqualifying when it is transparent and appropriately managed. The red flag is undisclosed or contradictory positioning, such as an intermediary being paid by the seller while promising exclusive buyer loyalty, discouraging independent review, or presenting only its own listings as a whole-market search.
