Merkantiler Minderwert: A Claim Despite a Fully Repaired Car

Merkantiler Minderwert (the loss in market value a repaired vehicle retains despite a technically flawless repair) is the amount your car is worth less by, purely because it once had an accident.

A buyer generally pays less for a vehicle with a known accident history, even where the repair was carried out to a technically flawless standard — the mere duty to disclose it on resale pushes the price down. The party at fault reimburses this Minderwert (diminished value) as a separate head of damage alongside the repair cost. It arises with the accident itself and is therefore awarded even under a notional settlement, without having the car repaired; the position can differ if you sell the vehicle unrepaired — courts then treat the Minderwert as already priced into the resale value (Restwert) achieved.

Comprehensive cover (Kaskoversicherung): under many comprehensive-cover terms (AKB), merkantiler Minderwert is expressly excluded or only partly reimbursed. This affects only claims under your own comprehensive policy, not the claim against the other driver's liability insurer described here.

This reflects German law and German court practice.

Do I get Wertminderung even though my car is fully repaired?

Yes.

Do I get Wertminderung under a notional settlement too?

Yes, according to the prevailing case law. The claim does not depend on whether you actually have the car repaired. The Minderwert arises as soon as the accident happens, because from that moment the vehicle is an Unfallwagen (accident-damaged vehicle). The Bundesgerichtshof detached the claim from what becomes of the vehicle as early as 1961: it is reimbursed even to an owner who simply keeps driving it (BGH, judgment of 03.10.1961, VI ZR 238/60). Lower courts draw the consequence for a notional settlement (fiktive Abrechnung) from this: you are under no duty to repair, the claim falls due immediately, and it exists even under an abstract, i.e. notional, settlement (LG Memmingen, judgment of 08.01.2019, 33 O 1276/17).

What counts is the value your vehicle would still have after a proper repair. So the repair must be technically possible, not actually carried out. How you settle the claim does not affect the amount: the Minderwert is estimated from net sale prices regardless, whether or not you submit an invoice.

The opposing position: if you sell the vehicle on unrepaired, courts treat the Minderwert as already priced into the resale value (Restwert) achieved — a buyer of an unrepaired accident vehicle factors it into the price. An additional Wertminderung is then not awarded (LG Duisburg, judgment of 17.04.2014, 12 S 153/13). The same applies to a total loss (Totalschaden): where you settle based on the Wiederbeschaffungswert (replacement value) minus the Restwert, the Minderwert is already contained in that difference and is not paid again.

At what vehicle age does Wertminderung stop applying?

A rigid limit has not existed since 2004: the used-car market has changed, and valuation bodies now cover vehicles up to twelve years old. Even a well-maintained twelve-year-old vehicle can still suffer a diminished value in an individual case. There is no calculation method prescribed by case law — the amount is estimated by an expert case by case.

Honesty requires saying: the case law is not a one-way street. The Bundesgerichtshof (BGH) deducts the VAT share from the Minderwert where it was determined from gross prices — that works against the injured party. And even the 2004 landmark decision that abolished rigid age limits ended, in the specific case, with the diminished value being denied.
