German Law of Obligations (Schuldrecht)

General Part of the Law of Obligations

The German law of obligations (Schuldrecht) is codified in Book 2 of the Burgerliches Gesetzbuch (BGB), Sections 241-853. The General Part (Allgemeiner Teil, Sections 241-432) contains provisions applicable to all types of obligations, while the Special Part (Besonderer Teil, Sections 433-853) governs specific contractual types. The 2002 reform of the law of obligations (Schuldrechtsmodernisierung) fundamentally restructured the General Part, replacing the fragmented categories of non-performance with a unified system centred on the concept of breach of duty (Pflichtverletzung).

Types of Obligations

An obligation (Schuldverhaltnis) is a legal relationship between two or more persons under which one party (the debtor, Schuldner) owes performance (Leistung) to the other party (the creditor, Glaubiger). Section 241(1) BGB defines the basic obligation to perform; Section 241(2) BGB, introduced by the 2002 reform, establishes that an obligation may also require each party to have regard for the rights, legal interests, and interests of the other party (protective duties, Schutzpflichten).

Obligations are classified by source:

• Contractual obligations (vertragliche Schuldverhaltnisse): arising from lawful agreement
• Statutory obligations (gesetzliche Schuldverhaltnisse): arising from tort (unerlaubte Handlung, Sections 823-853 BGB), unjust enrichment (ungerechtfertigte Bereicherung, Sections 812-822 BGB), negotiorum gestio (Geschaftsfuhrung ohne Auftrag, Sections 677-687 BGB), and culpa in contrahendo (Verschulden bei Vertragsschluss, Section 311(2)-(3) BGB)

By content, obligations may be:

• Monetary obligations (Geldschulden): payment of money
• Obligations to do or refrain (Handlungs- oder Unterlassungspflichten): performance of an act or forbearance
• Generic obligations (Gattungsschulden): performance of a thing defined by general characteristics only (Section 243 BGB)
• Specific obligations (Stuckschulden): performance of a specific, individually determined thing

The Unified Concept of Breach of Duty

Central to the reformed Schuldrecht is Section 280(1) BGB: if the debtor breaches a duty arising from the obligation, the creditor may claim damages for the loss caused thereby, unless the debtor proves that the breach was not attributable to the debtor (Vertretenmussen). This single provision replaces the former tripartite structure of impossibility, delay, and positive malperformance. The burden of proof shifts to the debtor to demonstrate absence of fault.

Attribution (Vertretenmussen) is governed by Sections 276-278 BGB. Section 276 provides that the debtor is liable for intention (Vorsatz) and negligence (Fahrlassigkeit). Negligence is defined as failing to exercise reasonable care in the circumstances. A debtor may not be exculpated in advance for intentional conduct. Section 278 attributes the fault of the debtor’s legal representatives and vicarious agents (Erfullungsgehilfen) to the debtor. Section 279 imposes strict liability for generic obligations: where the debt is a generic obligation, the debtor is liable for inability to perform even without fault, until the thing is specificised.

Impossibility (Unmoglichkeit)

Impossibility is the situation where performance cannot be effected. The BGB distinguishes:

• Objective impossibility (objektive Unmoglichkeit, Section 275(1)): performance is impossible for everyone, e.g. the specific thing is destroyed. The claim for performance is excluded, and the debtor is released from the obligation.
• Practical impossibility (faktische Unmoglichkeit, Section 275(2)): performance requires disproportionate effort; the debtor may refuse performance. Whether effort is disproportionate depends on the content of the obligation and good faith.
• Personal impossibility (Section 275(3)): performance cannot be reasonably required of the debtor personally; applies only to personal services.

Where impossibility is caused by the debtor’s fault, the creditor may claim damages in lieu of performance under Section 283 BGB, or reimbursement of wasted expenditure under Section 284 BGB. Where impossibility is caused by the creditor, the debtor retains the claim for counter-performance but must deduct saved expenses (Section 326 BGB).

Delay (Verzug)

Delay (Verzug) by the debtor is governed by Sections 286-292 BGB. Delay requires: (1) a due and enforceable obligation; (2) a warning (Mahnung) by the creditor after the obligation becomes due, unless a calendar date for performance has been fixed or the debtor has seriously and finally refused performance; (3) the debtor’s fault (Vertretenmussen). The warning is a formal demand for performance; the burden of proving that the debtor was not at fault for delay lies on the debtor.

Consequences of delay include: (1) liability for all losses caused by delay (Section 280(2) BGB); (2) the debtor remains liable for performance even if performance becomes impossible during the delay, unless the impossibility would have occurred even without the delay (Section 287 BGB); (3) the debtor must pay interest at the statutory rate (five percentage points above the base rate for consumer transactions, nine percentage points for commercial transactions under Section 288 BGB); (4) the creditor may claim damages in lieu of performance after setting a grace period (Nachfrist) under Section 281 BGB.

Damages (Schadensersatz)

German damages law distinguishes between natural restitution (Naturalrestitution, Section 249 BGB) and monetary compensation (Geldentschadigung, Section 251 BGB). Natural restitution is the primary remedy: the injured party is entitled to be placed in the position that would exist if the duty had not been breached. Natural restitution may take the form of repair of damaged property, reversal of a transaction, or any other restoration of the status quo ante.

Where natural restitution is impossible, insufficient, or would require disproportionate effort, monetary compensation applies. Damages are measured by the difference method (Differenzhypothese): the injured party’s actual financial position is compared to the hypothetical position without the breach. The injured party may choose between the concrete calculation (konkrete Schadensberechnung), measuring actual losses, and the abstract calculation (abstrakte Schadensberechnung), measuring market loss without reference to the specific transaction.

The 2002 reform unified the damages framework. The distinction between the positive interest (Erfullungsinteresse or expectation) and negative interest (Vertrauensinteresse or reliance) remains relevant but operates within the unified Section 280 framework. The reform also introduced Section 284 BGB, allowing the creditor to claim reimbursement of wasted expenditure (vergebliche Aufwendungen) instead of damages in lieu of performance, in reliance on receiving performance.

Limitation of Claims (Verjährung)

The 2002 reform standardised limitation periods. The regular limitation period is three years (Section 195 BGB), running from the end of the year in which the claim arose and the creditor obtained or ought to have obtained knowledge of the circumstances giving rise to the claim and the identity of the debtor (Section 199 BGB). This knowledge-based commencement replaced the former system of fixed periods from accrual.

Longer periods apply for certain claims: real property claims (10 years, Section 196 BGB), personal injury claims (30 years from the event, Section 197 BGB), and claims based on final judgments (30 years, Section 197 BGB). The maximum period for claims for damages is 10 years from the damaging event or 30 years from the act (Section 199(3) BGB). Limitation periods may be extended by agreement within limits set by Section 202 BGB.

Concurrent Claims (Anspruchskonkurrenz)

German law recognises that multiple claims may arise from the same factual situation — concurrent claims (Anspruchskonkurrenz). Contractual and tortious claims may coexist: a defective product causing personal injury may give rise to claims under Sections 280, 823, and the Product Liability Act (Produkthaftungsgesetz). The general principle is that the injured party may pursue any and all available claims, subject to the prohibition of double recovery. The choice between claims may affect limitation periods, burden of proof, and the scope of recoverable damages, particularly the availability of damages for pure economic loss (available in contract but limited in tort).
