Two landmark decisions of the Federal Court of Justice (BGH) established the liability of real estate valuers towards third parties who did not enter into a contract with the valuer: BGH III ZR 50/94 of 10 November 1994 and BGH X ZR 250/02 of 20 April 2004. The first decision opened the protective scope of the appraisal contract to the specific property purchaser; the second decision extended this protection to an unnamed multitude of capital investors. Both judgments are based on the legal doctrine of the contract with protective effect for third parties and are relevant to every valuer whose appraisal report is recognisably intended to serve as a basis for decision-making by third parties.

BGH III ZR 50/94 of 10 November 1994 (BGHZ 127, 378): The purchaser as a protected third party

Facts of the case: In March 1988, an architect and publicly appointed building expert prepared a value appraisal report for the seller of a house property, using the standard form of a district savings bank (Kreissparkasse). The report attested to the property's good structural condition. The claimants purchased the property – evidently relying on this report. In the purchase agreement, the seller's liability for defects was excluded. In 1989, when renovation work began, the claimants discovered significant moisture damage and structural defects in the roof truss that required a complete rebuild. The claim for damages against the seller failed due to the exclusion of liability for defects; the claimants then turned against the valuer.

Decision: The BGH overturned the appellate judgment dismissing the claim. The claimants, as purchasers, are included within the protective scope of the appraisal contract between the seller and the valuer.

Key statement: "Persons who are called upon to provide appraisal reports on the basis of special, state-recognised expertise, and who issue such reports in that capacity, are liable, under the principles of a contract with protective effect for third parties, towards those to whom the client uses the appraisal report as intended."

The BGH emphasises three key elements in this regard: First, publicly appointed and sworn valuers enjoy special trust due to their state-recognised status, which they cannot shield themselves from by choosing their contractual partner in the face of extended liability. Second, the inclusion of third parties presupposes "use as intended": the valuer knew or must have known that his appraisal report would be presented to third parties as a basis for decision-making. Third, fraudulent conduct on the part of the client does not exonerate the valuer: protection of the bona fide purchaser would be rendered ineffective if liability could be circumvented through the seller's fraudulent involvement.

BGH X ZR 250/02 of 20 April 2004 (BGHZ 159, 1): The unnamed multitude of capital investors

Facts of the case: A valuer prepared a value appraisal report for a property in April 1994. The report expressly stated its purpose as "planning and financing purposes"; the market value determined was approximately DM 11.7 million. The client used this appraisal report to secure a bond that he placed with private capital investors. The investors purchased the bond relying on the property value determined by the appraisal report as a basis of security. Following the client's insolvency, they suffered significant losses. One investor sued the valuer for damages.

Decision: The BGH overturned the appellate judgment dismissing the claim and significantly expanded the group of third parties included within the protective scope.

Official headnote b): "An unnamed multitude of private lenders or capital investors may be included within the protective scope of an appraisal engagement if the valuer knew or had to reckon, based on the content of the appraisal engagement given to him, that the client would use the appraisal report to obtain credit, limited in amount, secured by a mortgage on the property."

The BGH clarifies that the objective declaratory content of the appraisal report itself is decisive for determining the protective scope. A statement of purpose such as "planning and financing purposes" deliberately opens the protective scope widely – as it signals that the appraisal report is intended to serve as a basis of security for credit operations in which an unnamed multitude of persons may be involved. At the same time, the BGH emphasises that the extension to a broad group of persons does not increase the liability risk without limit: if, instead of a single lender, many investors use the same appraisal report, the total exposure remains calculable due to the limitation to the value of the mortgage.

The two decisions in context

Both judgments are based on the same doctrinal foundation – the contract with protective effect for third parties (Sections 157, 242 of the German Civil Code (BGB), Section 328 BGB by analogy) – but differ in the scope of protection:

In BGHZ 127, 378 (1994), the third party is a named individual: the purchaser of the property. The valuer knew or had to know that a specific purchaser would use his appraisal report as a basis for decision-making. In BGHZ 159, 1 (2004), the third party is an unnamed multitude. The valuer need not know the investors – it is sufficient that he had to recognise, from the content of the appraisal report or the engagement, that his appraisal report would serve as a basis of security for financing operations in which third parties are involved.

Practical Consequences for Valuers

Formulate the intended use precisely: Stating the purpose in the appraisal report is not merely a formal obligation, but directly determines the group of third parties protected under liability law. Open formulations such as "financing and planning purposes" open the protective scope widely. Anyone valuing solely for a specifically known client should expressly state this in the appraisal report.

No safe harbour through the client's conduct: The fact that the client misused the appraisal report for their own purposes or withheld relevant information from the valuer does not fully exonerate the valuer. As long as the valuer could have identified defects through a proper inspection, liability remains.

Adjust professional indemnity insurance: The expansion of the potential group of claimants to an unnamed multitude of capital investors means, in practice, a significantly increased exposure to damages. Valuers who prepare mortgage lending value reports for banks or real estate appraisal reports in the context of capital market products should take this into account when sizing their professional indemnity insurance.

Focus on publicly appointed valuers: Both decisions emphasise the heightened trust that publicly appointed and sworn valuers enjoy. This advance of trust is at the same time a liability risk: anyone claiming state recognition of expertise for themselves will be measured against a correspondingly high standard.
