GermanyWhat is the diminished value claim after an accident?
In Germany, diminished value (merkantiler Minderwert) is the measurable drop in a vehicle’s market value after an accident—even if fully repaired—and is recoverable as monetary compensation under BGB § 251.
What the Law Says
German law recognizes that a vehicle’s market value can fall permanently after an accident—even when repairs are flawless. This 'merkantiler Minderwert' (commercial depreciation) is treated as compensable damage under the general principles of tort-based compensation.
Under BGB § 251, if restoring the damaged item (e.g., a car) is impossible or insufficient to fully compensate the injured party, the liable party must pay monetary damages instead. This applies even when physical repair is technically complete—because the vehicle’s resale value remains objectively lower.
Paragraph (2) adds that monetary compensation is also due when restoration would require disproportionate expense—but notably, this exception does *not* apply to diminished value claims. Courts consistently hold that the mere fact a car’s market value drops post-accident—even by 10–30%—does not make repair ‘disproportionate’; rather, the lost value itself is a separate, compensable harm.

What Courts Have Said
Germany’s highest civil court—the Bundesgerichtshof (BGH)—has repeatedly affirmed that diminished value is a real, quantifiable loss and must be compensated regardless of perfect repair.
The BGH confirmed that merkantiler Minderwert is a legally recognized component of damage compensation. Even after professional, factory-standard repair, buyers discount accident-damaged vehicles—making this loss objectively provable and recoverable from the at-fault party.
While primarily about loss-of-use compensation, this ruling reinforces the principle that intangible losses (like diminished marketability) qualify as compensable damage under BGB § 251—supporting the broader recognition of non-physical harms in traffic accident claims.
What to Do
Obtain a certified expert appraisal (Gutachten) documenting pre- and post-accident market values.
Submit the appraisal and repair invoices to the at-fault party’s liability insurer.
If denied, file a formal claim citing BGB § 251 and BGH VI ZR 357/20.
Consider small claims court (Amtsgericht) for claims under €5,000—no lawyer required.
