Hidden Defects in Czech Real Estate: What Can the Seller Be Liable For?

In simple terms: After selling a property in the Czech Republic, the seller may be liable for a hidden defect if the defect already existed at the time of transfer or handover, the buyer could not reasonably discover it during a normal viewing, and the buyer reported it in time. This does not mean that the seller is responsible for every problem that appears after the buyer moves in. In practice, the key questions are the technical condition at the time of sale, how the property was described in the purchase agreement, what documents were handed over, and how quickly the buyer notified the seller.

This is important when selling a house, apartment, recreational property, investment property or land. Good preparation before the sale is usually less expensive than a later dispute with the buyer.

What Is a Hidden Defect in Czech Real Estate?

A hidden defect is, in simple terms, a problem that already had its origin at the time of sale or handover, but the buyer could not reasonably discover it during a standard viewing and with normal attention.

It is not enough that the problem appeared only after the buyer moved in. In most cases, it is necessary to assess whether the cause of the defect already existed earlier.

Examples of situations that are often checked as possible hidden defects include:

long-term roof leakage covered by new paint,
damp or mould hidden behind built-in furniture,
faulty electrical or water installations,
a sewer defect that appears only during normal use,
a structural problem that was not visible during the viewing,
a heating system defect that appears only during the heating season.

On the other hand, normal wear and tear of an older property does not automatically qualify as a hidden defect. An old house cannot usually be expected to be in the same condition as a new build. That is why it matters how the property is presented, what is written in the purchase agreement and what information the buyer received before signing.

What Can the Seller Be Liable For?

The seller may be liable mainly for defects that the property had at the time of transfer of ownership or at the time of handover to the buyer. It is not always only about whether the seller knew about the defect. What often matters is whether the defect existed, whether it was hidden and whether it affected the property’s qualities, value or normal use.

A seller may be liable even for a defect they did not know about if the property had defective qualities at the relevant time and the legal conditions for liability are met. If the seller knew about the defect and failed to disclose it to the buyer, the seller’s position is usually significantly worse.

The Defect Already Existed at the Time of Sale

For example, the buyer discovers after several months that water is leaking into the house. If an expert report shows that the cause of the leakage existed before the sale, it may be a defect for which the seller can be liable.

It is important to distinguish between the cause and the visible effect of the defect. A problem may appear only after handover, but its technical origin may be older.

The Seller Knew About the Defect and Did Not Disclose It

This is a more risky situation for the seller. If the seller knew about a defect, they should inform the buyer before the purchase agreement is signed.

Failing to disclose a known defect may significantly worsen the seller’s position in a dispute. It is not only about the defect itself, but also about trust, documentation and proving what information the buyer received before buying.

The Property Does Not Match What Was Agreed

A problem may also arise if the property was described more positively than the actual condition justifies.

For example, if the listing or purchase agreement says that the property has been fully renovated, but in fact major utility installations are still original and defective, this can create a risk for the seller. This is why the condition should not be exaggerated.

In other words: an older house after partial upgrades is not the same as a fully renovated property.

Important Technical Information Is Missing

For older houses, recreational properties or properties after partial renovation, I recommend preparing an overview of completed repairs, known defects, inspections, service reports and available documentation.

Transparency does not automatically mean a weaker negotiating position. On the contrary, a seller who can support the property’s condition with documents can usually explain the price better and reduce the risk that the buyer later describes the issue as a concealed defect.

What Is the Seller Usually Not Liable For?

The seller is generally not responsible for everything that breaks after the sale. Each case must be assessed individually, but the seller is often not liable if:

the defect arose only after the property was handed over,
the buyer knew about the defect and still bought the property,
the defect was visible during a normal viewing,
it was normal wear and tear corresponding to the property’s age and condition,
the buyer was expressly informed about the worse technical condition,
the problem resulted from improper use or neglected maintenance after handover.

A typical example is an older house sold for renovation. The buyer of such a property cannot automatically expect the condition of a new build. Even so, it is better to describe the condition specifically rather than relying on a general phrase.

How Long Can the Buyer Raise a Hidden Defect?

For a building connected to the ground by a solid foundation, the Czech Civil Code works with a five-year final time limit for notifying a hidden defect. The current wording of the Civil Code should be checked through e-Sbírka or the Czech Public Administration Portal.

However, this does not mean that the buyer may wait for years after discovering the defect. In decision file no. 23 Cdo 506/2025, the Czech Supreme Court stated that the buyer must notify such a hidden defect without undue delay after they could have discovered it with sufficient care.

For the seller, this is important. If the buyer reports the defect late, a key issue in a potential dispute may be when the buyer found out about the defect, when they could have discovered it, and whether they reacted in time.

What Can the Buyer Claim?

If the hidden defect is justified and reported in time, the buyer may, depending on the circumstances, request for example:

removal of the defect,
a reasonable discount from the purchase price,
compensation for related loss if the legal conditions are met,
in serious cases, withdrawal from the purchase agreement.

In practice, the most common solution is a discount from the purchase price or an agreed financial compensation. Withdrawal from the purchase agreement is usually a last resort for serious defects that substantially prevent the use of the property or change the purpose of the purchase.

What Should the Seller Check Before the Sale?

The risk of a later claim cannot be removed completely. But it can be significantly reduced by naming known defects, collecting documents and not describing the technical condition better than it actually is.

1. Do Not Hide Known Defects

If you know that water sometimes enters the cellar, the boiler has recurring issues or part of the renovation was never completed, it is better to disclose it before the sale.

A concealed defect can return after the sale as a much more expensive problem — financially, legally and in terms of time.

2. Prepare the Documentation

Before the sale, it is useful to collect documents that show the technical condition and the history of work done on the property, such as:

project documentation,
inspection and service reports,
invoices for renovation works,
occupancy approval or building approval documents,
Energy Performance Certificate, if required,
documents for a well, wastewater treatment plant, septic tank or utility connections,
documents relating to repairs of the roof, heating, windows or utility installations.

A common problem is that owners of older houses have almost no technical documents, inspections or Energy Performance Certificate available. That is why it is better to deal with documents before the property is publicly offered.

For apartments, it is also useful to prepare information from the homeowners’ association / SVJ, the balance of the repair fund and planned larger repairs of the building.

3. Describe the Property Condition Accurately

The listing and the purchase agreement should match reality. If the house is older and has undergone only partial renovation, it is better to state this clearly.

Phrases such as “fully renovated” may be risky if they apply only to part of the property. It is more accurate to say what was actually done: for example, window replacement, partial bathroom renovation, roof repair or new wiring in part of the house.

4. Consider a Technical Inspection Before the Sale

For older houses, cottages, investment properties or buildings after renovation, a technical inspection before launching the sale can be very useful. It is not only protection for the buyer. It also helps the seller because it shows weak points before price negotiations or before signing a reservation agreement.

When preparing the sale of older houses, I always ask the owner about the technical condition and the history of repairs. I want to know what has been renovated, whether there are invoices, inspection reports or project documentation, and whether the property has had recurring issues such as damp, roof leakage, heating problems, sewer problems or electrical defects. If documents are missing or the condition is uncertain, I recommend a technical inspection before the property is listed.

A technical inspection may reveal not only a technical defect, but also a possible discrepancy between the actual condition of the property and the project, occupancy approval or other building documentation. This may concern, for example, an extension, garage, layout change, different use of part of the house or building works where it is necessary to verify whether they were properly permitted and documented. For the seller, it is better to find out about such an issue in advance and, depending on the situation, start dealing with it with the building authority before it appears during negotiations with the buyer, during mortgage financing or after the purchase agreement has been signed. At that stage, it can affect the price, timing and trust between the parties.

A technical report may cost tens of thousands of Czech crowns, but for an older or poorly documented house it often pays off. The seller has a clearer understanding of what they are selling, the buyer receives more specific information and the risk of the issue being raised only after the transfer is reduced.

5. Deal With the Condition in the Purchase Agreement

The purchase agreement should not rely only on a general sentence saying that the buyer is familiar with the condition of the property. It should reasonably describe known defects, the technical condition, documents handed over and seller’s representations.

For legally sensitive clauses, I recommend working with an attorney. A poorly drafted agreement may not protect the seller when the buyer raises a defect.

When ownership of real estate is transferred in the Czech Republic, the contractual documents are followed by an application for registration with the Land Register. The Czech Office for Surveying, Mapping and Cadastre provides an application for registration and recommends using its interactive application, which includes automated steps and checks.

For the escrow of the purchase price, it is important to check not only the type of escrow, but also the conditions for releasing the money. The Czech Bar Association states that attorneys report monetary escrows into the Electronic Escrow Register.

Hidden Defects in a House, Apartment and Land

Family House

For family houses, the most commonly checked issues include damp, roof condition, structural stability, utility installations, heating, sewer system, drainage and the quality of renovation works.

Older houses in South Bohemia, the Vysočina Region or Central Bohemia often combine original structures with newer modifications. This makes an accurate description of the condition especially important.

Apartment

In apartments, defects may appear inside the unit as well as in relation to the building.

Buyers often ask about electrical wiring, waste pipes, damp, windows, balcony or loggia, noise, condition of common areas or planned repairs by the homeowners’ association / SVJ. The seller should provide the buyer with available information.

For a housing cooperative apartment, it is also necessary to remember that the ownership of the unit itself is not transferred. Instead, the cooperative share is transferred. Even there, however, it makes sense to describe the apartment’s condition and available information accurately.

Land

For land, hidden defects are more often legal, technical or factual restrictions.

They may concern access, utility networks, easements, old environmental burdens, unsuitable subsoil or a mismatch between expected and actual permitted use. For building land, it is important to check the zoning plan, access and the possibility of connecting to infrastructure.

What to Do If the Buyer Reports a Hidden Defect After the Sale

If the buyer contacts you claiming that they have found a hidden defect, do not react emotionally and do not admit anything without verification.

First, ask for written notification of the defect, photos, a description of the problem, information on when the buyer discovered it and, if available, an expert statement. Only then does it make sense to assess whether the defect could have existed at the time of sale, whether it could have been discovered during the viewing and whether it was reported in time.

For technical defects, an independent expert is often helpful. For legally more complex issues, it is advisable to involve an attorney. The goal does not always have to be a dispute. If the claim is justified and the compensation corresponds to the real scope of the problem, a reasonable agreement may be better.

Without verification, however, it is not advisable to automatically accept the claim or reject it only because the problem appeared after the sale.

The Best Protection for the Seller Is Good Preparation

Hidden defects are not only a legal issue. They are mainly about trust, documentation and a properly prepared sale.

When I prepare a property sale with an owner, I deal not only with price and marketing, but also with the property’s condition, documents, risk areas and how the property is presented. For a house, apartment, land or recreational property, it is better to resolve problematic points in advance than to explain them after the purchase agreement has been signed.

A transparent sale does not have to mean a lower price. It means that the buyer understands what they are buying and the seller can better prove what condition was described and what documents were handed over before signing.

FAQ: Hidden Defects in Czech Real Estate

Is the seller liable for hidden defects even if they did not know about them?

Possibly yes. In defective performance cases, it is often assessed whether the defect existed at the time of sale and whether it was hidden, not only whether the seller knew about it. If the seller knew about the defect and concealed it, the seller’s position is usually much worse.

Is every problem after purchase a hidden defect?

No. A hidden defect must have its origin at the time of sale or handover, and the buyer must not have been able to discover it during a normal viewing. A defect that arises only after handover usually does not go against the seller.

How long after purchase can the buyer claim a hidden defect?

For a building connected to the ground by a solid foundation, a five-year objective time limit is relevant. However, the buyer must notify the defect without undue delay after discovering it or after they could have discovered it with sufficient care. Waiting is not advisable.

Does a clause saying that the property is sold “as is” protect the seller?

Such a phrase alone may not safely release the seller from liability for hidden defects. A specific description of the condition, known defects, handed-over documents and the real qualities of the property is more important.

Can the seller completely exclude liability for hidden defects?

A full exclusion of liability is legally sensitive and may not be effective in all situations, especially if the seller knew about the defect or concealed it. A safer approach is to disclose known defects, document them properly and prepare the purchase agreement with a professional.

What should the seller hand over to reduce the risk of a dispute?

Ideally, documents relating to the technical condition, inspection reports, service reports, information from the homeowners’ association / SVJ, documents for renovations and a list of known defects. The information handed over should match the listing and the purchase agreement.

What should I do before selling an older house in the Czech Republic?

I recommend checking the technical condition, listing known defects, collecting available documents, verifying the Energy Performance Certificate and, for older or poorly documented houses, considering a technical inspection before launching the sale. Sometimes this check reveals a problem that would otherwise appear only during negotiations with the buyer or after the purchase agreement has been signed.
