What to check in the Land Registry before buying a flat? Key entries and pitfalls

Buying a flat is one of the most important financial decisions in one's life, so each stage of the transaction should be preceded by a thorough analysis of the documents. One absolutely key source of information about the legal status of a property is the land register. Regardless of whether you plan to buying a flat in Gdańsk, in another city in the Tricity or you use the help of a professional broker, an analysis of the land register allows you to avoid costly mistakes and legal pitfalls.

In practice, even experienced buyers make mistakes, overlooking provisions that at first glance seem unimportant. However, it is precisely these that can determine the safety of the transaction. We explain below, what to check with the land register before buying a flat, how to read its various sections and which warning signs to pay particular attention to.

What is the land register and why it is crucial when buying a flat

The land register is a public register kept by the district courts to reveal the legal status of a property. It contains information about the owner, the rights attached to the property and any encumbrances. Thanks to the principle of openness, anyone can check it online, even before signing the preliminary contract.

From the buyer's point of view, the land registry has a protective function. It is on its basis that the notary assesses whether the property can be safely sold. In cities with a highly dynamic market, such as Gdańsk or the entire Tricity, where loan transactions and sales of flats from the secondary market are frequent, an analysis of the land and mortgage register is an absolute basis for a safe purchase.

How the land register is structured - division into sections

Each land register consists of four separate sections, each of which has a different function and relates to a different aspect of the legal status of the property. This division is not accidental - it allows information on the property itself, its owner and any rights and encumbrances to be presented in an orderly manner. This allows a person planning to purchase a flat to analyse all the key elements of the transaction step by step.

Importantly, each section of the land and mortgage register requires a separate and informed analysis, as the omission of even one of them may lead to erroneous conclusions. The information contained in the individual sections complements each other, and only reading them together gives a complete picture of the legal situation of the premises. In practice, this means that without checking all sections, it is impossible to reliably assess the security of a property purchase.

Section I - Designation of immovable property and rights connected with ownership

In the first section, you will find data identifying the property, such as address, apartment number, floor space and information on belongings. It is worth carefully comparing these details with the offer and the contract, as discrepancies in the floor area or the absence of an entry regarding a cellar or parking space are common problems when buying a flat.

You should also check whether the right to use common elements, such as parking spaces or gardens, is actually disclosed in the register. The absence of such an entry may mean that the use has no legal basis.

Section II - Owner or joint owners

Section II shows who owns the property and in what share. This is one of the most important sections of the ledger, as only the persons indicated therein can effectively sell the flat. If the property has several co-owners, all of them must agree to the sale.

Particular care should be taken with flats acquired by inheritance or donation. In such cases, it is advisable to ensure that the inheritance proceedings have been validly concluded. Experienced real estate office in Gdansk usually verifies these issues, but the ultimate responsibility rests with the buyer.

Section III - Rights, claims and restrictions

Section III is the place that often determines whether a transaction is secure. Here you will find entries relating to easements, claims, third party rights and pending enforcement proceedings. Particular attention should be paid to personal easements, such as the right to reside for life, which can significantly restrict the use of the premises.

It is worth bearing in mind that the presence of entries in Section III does not always mean that the purchase must be abandoned, but requires careful analysis and often additional security provisions in the preliminary agreement.

Section IV - Mortgage

Section IV informs about mortgages encumbering the property. Contrary to popular belief, a flat with a mortgage does not have to be a problem as long as the deletion of the mortgage takes place at the time of sale. It is standard practice to repay the seller's loan from the purchase price and to cancel the mortgage after the notarial deed.

However, it is crucial to establish whether the mortgage will actually be cancelled and whether the bank will issue the appropriate certificate. Failure to do so can result in serious post-purchase complications.

The most common pitfalls in the land register

The most common pitfalls include outdated entries, discrepancies between the contents of the register and the actual legal status and the absence of an established land register. Particularly risky are situations in which the seller assures that „everything is in place”, but cannot confirm this with documents.

In the case of flats without a land register or with a register yet to be established, buying a flat in the Tricity requires special care and consultation with a notary.

Buying a flat with the help of an estate agent - what you still need to check

Working with a professional intermediary significantly facilitates the analysis of documents, but does not relieve the buyer of basic knowledge. Even the best real estate office in Gdansk operates on the basis of documents provided by the seller, so it is always a good idea to consult the land register yourself.

An informed buyer can ask the right questions and spot potential risks more quickly before signing binding documents.

What to do if there are irregularities in the land register

If irregularities are detected, no hasty decisions should be taken. Some of the problems can be solved even before the notarial deed is signed, e.g. by completing the documents or inserting appropriate provisions in the preliminary agreement. However, if the risk is significant, the best solution is to hold off on the transaction until the situation is fully clarified.

Summary

Checking the land register is a key element of a secure the purchase of a flat, as it allows the actual legal status of the property to be verified. Analysis of the entries makes it possible to confirm the owner, the extent of his/her rights and to detect possible encumbrances, such as mortgages, claims or easements, which may significantly affect the ability to use the property after purchase.

Particular attention should be paid to all four sections of the land register, as each section is responsible for a different area of risk. It is only by assessing the ledger data as a whole that it is possible to properly prepare for the transaction, to plan the appropriate safeguards in the preliminary agreement and to avoid problems at the notarial deed stage.

The support of a professional real estate offices in Gdańsk can make the process easier, but the ultimate responsibility for checking the land register always rests with the buyer.

FAQ - Frequently asked questions

1) Is it safe to buy a flat with a mortgage?

Yes, provided you have a clearly described procedure for repayment of the seller's loan and a document from the bank confirming the conditions for deletion of the mortgage after the transaction. In practice, it is safest if part of the price goes directly to the bank and there are provisions in the deed to protect the buyer.

2) Does the absence of entries in Section III mean that the flat is legally „clean”?

The absence of entries in Section III is a good signal but not a guarantee of complete security, as some events may not yet be disclosed in the ledger or are pending. Therefore, it is advisable to check whether there is any mention of filed applications in the ledger and, in addition, to verify the seller's documents (e.g. the basis of acquisition, certificates and statements in the deed).

3) What if there are several owners or spouses in Section II?

In such a situation, the consent of all co-owners is needed for the sale, and with matrimonial community of property, the presence or consent of the other spouse is often required. If at least one person is not prepared to sign the agreement, the transaction may be delayed or impossible, so it is worth establishing this before you pay the deposit.

4) How do I check that the land register is up to date and that there are no „hidden” changes?

The most important thing is to verify that there are no mentions of new applications in the ledger, as these may indicate upcoming entries (e.g. bailiff attachment, claim or change of ownership). In addition, it is advisable to ask the seller for the current source documents (e.g. succession order, donation agreement) and compare them with the contents of the ledger.

5) Is it possible to buy a flat without a land register and what are the risks involved?

It is possible, but requires particular care, as it is then more difficult to confirm the legal status, encumbrances and title in a manner comparable to the KW. In practice, such a transaction should be preceded by a thorough analysis of the documents and consultation with a notary, and financing by credit is sometimes difficult or impossible in such cases.
