German BGH: Abstract Debt Acknowledgment after Lapsed Claim

The German Federal Court of Justice (Bundesgerichtshof, hereinafter BGH) had to determine whether enforcement may proceed on the basis of a standalone notarial acknowledgement of debt when the underlying claim has already become time barred.

Abstract acknowledgement of debt

In the case at hand, the plaintiff was a member of a general partnership (OHG) that had obtained an overdraft from a bank. In 1997, the bank demanded a notarised debt acknowledgment that allowed for immediate compulsory enforcement against all personal assets as security, without requiring a land or any other type of collateral. Several years subsequently, the bank assigned its rights under the acknowledgment of debt to the defendant, who proceeded to exercise and enforce those rights. Even though the claim based on the acknowledgment of debt remained within the statutory limitation period, the debtor raised a limitation defense against the original loan claim.

Inadmissibility of enforcement after expiration of the underlying claim

The BGH upheld the decisions of the lower courts and declared the compulsory enforcement inadmissible. While a claim based on a notarial document is subject to a 30-year limitation period pursuant to Section 197 (1) No. 4 of the German Civil Code (Bürgerliches Gesetzbuch, hereinafter BGB), it is crucial to note that once the underlying claim has expired, the creditor shall no longer retain a legitimate interest in upholding the acknowledgement of debt.

The acknowledgement of debt, having been expressly issued to safeguard the claim pursuant to Section 812(2) of the BGB, is considered an object of enrichment. Consequently, the debtor may request the return of the item once the principal claim is no longer enforceable. This aligns with the principle of condictio ob causam finitam as set forth in Section 812(1), sentence 2, case 1 of the BGB. In accordance with the principle of good faith, the creditor is precluded from seeking payment based on an acknowledgement of debt that, from a substantive legal standpoint, must be returned.

The court considers the thirty-year limitation period for enforceable instrument claims to be logically irrelevant, not a conflict of values. While the claim arising from the acknowledgment of debt remains within the statute of limitations, the underlying purpose of securing a debt becomes unattainable once the original claim has lapsed. This alignment of objectives provides the rationale for permitting the debtor to request the return of the acknowledgment of debt prior to the expiration of the limitation period, thereby precluding compulsory enforcement.
