More than three and a half years ago, the German law of obligations, codified in the second of the five books of the German Civil Code (Bürgerliches Gesetzbuch, BGB), underwent its greatest reform since the BGB was enacted on 1 January 1900. The Act to Modernize the Law of Obligations, the Schuldrechtsmodernisierungsgesetz, which came into force on 1 January 2002, dramatically altered the law of obligations. Whereas legal practitioners had almost no time to adapt to the new provisions, at least the German courts were granted a grace period. Nevertheless, by now the first cases involving the modernized law have reached the benches of the Bundesgerichtshof (BGH – Federal Court of Justice).
This article deals with “one of the currently most controversially discussed questions” of the law of obligations: Whether a buyer, who cures a product's defect can claim reimbursement for the associated expenses (Aufwendungen) from the seller, without giving the seller an additional period of time for supplementary performance (Nacherfüllung). This manner of bringing the product into conformity with the contract can be described as a premature self-cure (verfrühte Selbstvornahme).
