Hidden Defects When Buying a House in Germany: Seller and Agent Liability

When a hidden defect comes to light after a property purchase in Germany, the outcome depends heavily on two provisions of the German Civil Code (Bürgerliches Gesetzbuch, or BGB) — the primary statute governing private law relationships in Germany.

Section 442 BGB: Buyer’s Knowledge

Section 442 BGB provides that a buyer’s rights regarding a defect are excluded if the buyer was aware of the defect at the time of entering into the contract. If the buyer’s ignorance of the defect was the result of gross negligence, the buyer may assert rights only with respect to that defect if the seller fraudulently concealed it or provided a guarantee of the property’s condition.

This provision is particularly relevant in the context of hidden defects. The question of gross negligence typically arises only in relation to open defects — those that would have been visible upon reasonable inspection. Hidden defects, by their nature, are those that cannot readily be identified even with careful examination. Gross negligence on the part of the buyer is therefore generally not an issue where the defect was concealed.

Section 444 BGB: Exclusion of Liability

Section 444 BGB provides that a seller cannot rely on any agreement that excludes or limits the buyer’s rights in respect of a defect, to the extent that the seller fraudulently concealed the defect or provided a guarantee as to the condition of the property.

Purchase contracts in Germany frequently include clauses that exclude the buyer’s warranty rights. However, Section 444 BGB provides that such exclusions apply only where the seller did not fraudulently conceal the defect, and fraudulent concealment can apply only to defects that were not already apparent to the buyer. In other words, a liability exclusion clause offers a seller no protection where a hidden defect was deliberately withheld.

German case law is clear on this point: where a defect is open and visible, the seller has no duty to draw it to the buyer’s attention. The disclosure obligation arises specifically in relation to hidden defects. Any breach of duty in the context of inadequate disclosure will therefore relate to the latter category only.

Where a seller breaches an existing duty of disclosure, the buyer has several potential remedies.

The buyer may first demand supplementary performance under Section 439 BGB — that is, require the seller to remedy the defect. In practice, this is often not feasible, particularly where structural or latent issues are involved.

Where supplementary performance is impossible or fails, the buyer may withdraw from the contract or seek a reduction in the purchase price under Sections 440 and 441 BGB. This requires the defect to be material.

Where the buyer has suffered additional loss as a result of the defect, and the seller is at fault, a claim for damages may also arise.

Finally, rescission of the purchase contract on grounds of fraudulent misrepresentation under Section 123 BGB may be available. A successful rescission renders the contract void with retroactive effect, entitling the buyer to demand repayment of the purchase price.

Claims may also arise against the estate agent for breaches of disclosure obligations.

In its November 10, 2016, decision, the German Federal Court of Justice (Bundesgerichtshof, or BGH — Germany’s highest civil court) confirmed that a relationship of special trust exists between an agent and their client. This gives rise to secondary duties alongside the agent’s primary service obligation. As a representative of their client’s interests, agents are required to act in their clients’ best interests at all times. This means the agent must disclose not only information strictly necessary to protect the client from harm, but also all facts known to the agent that could be material to the client’s decision.

This duty of disclosure applies, in principle, to both parties when an agent — as is legally permissible in Germany — acts under contract with both the seller and the prospective buyer. The precise scope of the duty depends on the specific circumstances of the case.

A breach occurs in particular where the agent affirms certain characteristics of the property or passes on information — whether from their own knowledge or sourced from a third party — without having verified an adequate factual basis for those statements. Where the agent lacks reliable information, they must, at a minimum, make this clear to the client.

That said, there is no general obligation on the agent to volunteer information speculatively or without a concrete basis for doing so. Where there is no specific need for disclosure on the client’s side, no advisory duty arises. It is for the client to communicate clearly to the agent which interests, objectives, or specific purposes are relevant to the intended transaction — only then can the scope of the information and advisory obligations be properly assessed.

An agent’s disclosure obligations are also limited to matters of which they are actually aware. There is no general duty to investigate or to make independent inquiries. However, the agent must inform the client where their own knowledge is limited or where they are passing on unverified statements from third parties.

In the absence of specific circumstances suggesting otherwise, a buyer may generally assume that the information in a property listing reflects details provided by the seller. An agent is entitled to pass on information obtained and verified by the seller with appropriate care, without conducting independent checks. An exception applies, however, where the information is recognizably incorrect, implausible, or otherwise obviously questionable from the perspective of a competent agent. In such cases, the agent may not simply pass the information on without further scrutiny.

Where an agent makes false or contradictory statements about a property — for example, regarding the condition of the building or the nature of any defects — the agent may be liable where they acted intentionally or negligently, meaning the breach was their fault.

In assessing a claim of breach of disclosure duty against an agent, the key question is whether the agent knew, or ought to have known, of the fact in question. Any general terms and conditions in the agency contract should also be examined carefully, as these frequently include limitations on liability for cases of gross negligence and intent. The validity of such clauses must be assessed on a case-by-case basis.

Where the agent has committed a breach of duty, the buyer may generally refuse to pay the agency commission or seek damages directly from the agent. The agent’s breach may also give rise to claims against the seller. Rescission of the purchase contract is possible where the agent acted with deliberate intent to deceive — though in this scenario, the seller must also have been aware of the fraudulent misrepresentation, as required by Section 123(2) BGB. Where fraudulent misrepresentation is established, the buyer may typically also pursue claims for damages or warranty rights against the seller.

Acting promptly after discovering a hidden defect is essential. German law sets out specific limitation periods within which claims must be brought, and missing these deadlines can result in losing your rights entirely — regardless of how strong your underlying case may be.

Under Section 438(1) No. 2 BGB, warranty claims relating to defects in a building generally expire five years after handover of the property. This is the period most commonly relevant in the context of hidden defects in real estate.

Where the seller fraudulently concealed the defect, the position is different — and generally more favorable to the buyer. Section 438(3) BGB disapplies the standard warranty period and refers back to the general limitation rules under the BGB. This means a three-year period applies, but crucially, the clock does not start at handover. Instead, it runs from the end of the calendar year in which the buyer became aware — or ought reasonably to have become aware — of both the defect and the identity of the party liable. In practice, this is significantly more protective: a buyer who discovers a hidden defect several years after handover may have little time left under the standard five-year rule, whereas the fraudulent concealment exception gives them a fresh three-year window from the point of discovery.

The precise point at which a limitation period begins to run, and whether it may be suspended or interrupted in a given case, depends on the specific circumstances. We recommend seeking legal advice as early as possible after a defect comes to light, so that your options can be assessed before any deadline passes.

In cases involving hidden defects, the burden of proof generally rests with the buyer. This means the buyer must demonstrate that the defect existed at the time of handover and that the seller or agent breached an applicable duty of disclosure. This is frequently the most challenging aspect of such cases in practice.

Several forms of evidence may assist in meeting this burden. Expert reports play a particularly important role in establishing the existence and nature of defects. Building records and photographic documentation may also contain relevant material, and witness testimony can sometimes provide useful support. As a general rule, however, the evidentiary challenge is considerable. In claims against a seller based on fraudulent misrepresentation by an agent, the buyer must demonstrate not only the agent’s intent but also the seller’s knowledge.

A common mistake among buyers is failing to commission an expert report promptly — a delay that can significantly weaken the position when pursuing claims.

Preventive advice: Before completing a property purchase, we strongly recommend having the property thoroughly inspected by an independent expert.

Where a seller or agent refuses to accept liability, legal proceedings are often the only available route. The prospects of success depend on a range of factors, chief among them the demonstrability of the defect and the documented statements in the purchase contract and property listing.
