Rental car damage claim in Germany: who has to prove it?

Who has to prove the damage in Germany?

The rental company does. German courts require the lessor to prove the car’s condition both when you picked it up and when you returned it, and that the damage arose in between.

The clearest recent case is LG Münster, judgment of 11 October 2024, 10 O 52/24. The renter returned the car at night through a key box, and the company claimed €11,365. The court dismissed the claim in full: the lessor bears the burden of proof for the vehicle’s condition at handover and at return, and checkboxes in the rental contract do not shift it (Otto Schmidt report).

Other decisions agree:

• LG Lübeck, 6 March 2024, 6 O 82/23: there was no handover protocol, and a €5,500 claim was dismissed. The court gave the lessor no easing of its burden of proof (report).
• AG München, 12 February 2026, 191 C 13864/25: the car was moved between return and the expert inspection, so the damage could no longer be attributed to the renter. Protocol photos alone were not enough (report).
• LG Landshut 30.03.2011, 14 S 254/11; LG Berlin 18.11.2011, 56 S 36/11; LG Oldenburg 18.05.2012, 13 S 29/12: damage whose cause cannot be clarified does not fall on the renter.

One honest point before going further: this line of cases helps only if you did not cause the damage. If you did, the amount can still be checked: the repair invoice against the estimate, the fees, VAT and any loss-of-use charge.

Key-box and after-hours returns: the line you need to know

The lessor-friendly case law concerns after-hours returns, so read your contract first. In LG Hamburg, 15 November 2016, 309 S 38/15, the contract required return during opening hours with an inspection. The renters dropped the car off after hours, the risk stayed with them, and they lost. LG Lübeck, 13 June 2013, 14 S 211/11, belongs to the same line.

The facts in those cases matter. The car was inspected when the branch reopened the next morning, and there was a clean handover protocol. A gap of several days between drop-off and inspection, or documented movement of the car in that time, breaks the comparison. And LG Münster shows that a night key-box return does not by itself move the burden of proof onto you.

Collect now: the time you dropped the key, your return photos with their timestamps, the date of the company’s inspection, and anything showing the car was driven or moved before it. Our founder’s own €1,320 key-box claim from a rental in Graz, Austria was cancelled within 24 hours; here is how.

The six-month limit: § 548 BGB

A German lessor’s claims for damage to the car become time-barred six months after it gets the car back. The statute reads: “Die Ersatzansprüche des Vermieters wegen Veränderungen oder Verschlechterungen der Mietsache verjähren in sechs Monaten.” In English: the lessor’s compensation claims for changes or deterioration of the rented object are time-barred after six months. The period starts “mit dem Zeitpunkt, in dem er die Mietsache zurückerhält”, the moment the lessor gets the vehicle back (§ 548 BGB).

Check this first on any late claim. Limitation is a defence you must raise expressly in writing; it is not applied automatically. Take the return date from your contract or return receipt and count six months from there.

What can a German rental company charge?

The deductible is not a blank cheque

A deductible caps what you owe once your liability is proven; it does not prove liability. The Federal Court of Justice (BGH, 20 May 2009, XII ZR 94/07) held that a lessor who sells paid collision damage cover becomes a “Quasi-Versicherer” (quasi-insurer), and the renter may trust that the protection matches comprehensive insurance (report). The company still has to show the damage happened during your rental before the deductible comes into play.

Flat fees and admin charges

Rental terms are standard business terms (AGB) and subject to review:

• § 309 Nr. 5 BGB: a lump sum in the terms is void if it exceeds the damage typically to be expected, or if the terms do not expressly allow you to prove that “ein Schaden oder eine Wertminderung sei überhaupt nicht entstanden oder wesentlich niedriger als die Pauschale” (no damage arose, or it was much lower than the flat fee) (§ 309 BGB). A clause that fails is void in full, not reduced.
• OLG München, 28 February 2025, 39 U 4778/23 e: flat admin-fee clauses were held invalid under § 309 Nr. 5 BGB. The overhead of handling a claim is the claimant’s own cost.
• § 307 BGB: a clause that unreasonably disadvantages you contrary to good faith is invalid (§ 307 BGB).
• § 305c BGB: “Zweifel bei der Auslegung Allgemeiner Geschäftsbedingungen gehen zu Lasten des Verwenders”, doubts in interpreting the terms go against the company that wrote them (§ 305c BGB).
• § 312a Abs. 3 BGB: any payment beyond the agreed price for the main service can only be agreed expressly, and online not through a pre-set option (§ 312a BGB). This is the rule to check for cover added at the counter.

Fuel, cleaning and fine-handling fees after return

The charges seen in Germany after a rental include refuelling fees and a “Tankpauschale”, cleaning fees, damage-handling fees, handling fees for fines and tolls, late-return charges and card debits after return.

For fines, the courts are split. LG Frankfurt am Main (28 September 2023, 2-24 O 53/23, consumer association vzbv against Hertz Autovermietung GmbH) held a €40 flat fee per traffic or parking fine invalid, because the clause did not let customers show that no or a lower cost arose and did not tell them the company only forwards the fine. That judgment is not final; Hertz appealed. LG München (26 October 2023, 12 O 1830/23) held a similar Sixt clause permissible, and vzbv appealed (vzbv report). Ask for the fine notice and proof of what the company actually paid or did.

For fuel and cleaning, we have no verified German judgment on flat fees. The tests are § 307 and § 309 Nr. 5 BGB, and the facts decide: the fuel level on the check-out report, your fuel receipts, and the interior photos at return.

The company has to prove the contractual basis and the fact behind every charge. Ask in writing for the signed agreement and the terms in force, the check-out report, the itemised invoice, the fine or toll notice with proof of payment, and the card records. You can look up the terms we hold in the rental terms lookup.

Your card has already been charged

A debit does not make the charge owed. If a payment from your account was not authorised, your bank must refund it without delay and at the latest by the end of the business day after you notify it (§ 675u BGB).

Act quickly. § 676b BGB requires you to inform your bank “unverzüglich”, without undue delay, once you notice an unauthorised or incorrectly executed payment, and your claims against the bank are excluded if you report it later than 13 months after the debit date (§ 676b BGB). If the bank refuses, the Schlichtungsstelle bei der Deutschen Bundesbank or the Ombudsmann der privaten Banken handle disputes about the payment.

Collection letters and Schufa

A disputed claim must not be reported to Schufa, and threatening to do so is not permitted (BGH, 19 March 2015, I ZR 157/13, and § 31 BDSG). One written dispute sent to the collection agency is enough to make the claim “bestritten”, disputed.

In that letter, ask for the information a German collection agency owes consumers under § 13a RDG: the creditor, the basis of the claim, the interest calculation, the collection costs and their basis, and the supervisory authority. If the agency sends a debt acknowledgment (Schuldanerkenntnis) or a prepared settlement, do not sign it while you dispute the claim: signing typically gives up your objections and defences, including limitation.

Free help and court

• Verbraucherzentrale: the state consumer centres give advice and bring association actions.
• European Consumer Centre Germany (EVZ): free help for cross-border cases between a consumer and a company in another EU country.
• Universalschlichtungsstelle des Bundes: the general consumer dispute resolution body.
• ADAC: motoring clubs provide legal aid to their members.

If you live in another EU country, the rental company can sue you as a consumer only in the member state where you live (Brussels Ia, Art. 17(1)(c) and 18(2)). German law often still governs: for services performed exclusively abroad, the consumer conflict-of-law protection of Rome I (Art. 6(4)(a)) may not apply, and the terms’ choice of law, usually the pickup country, then decides.

What to do now

1. Find the return date and count six months. If the claim came later, raise § 548 BGB expressly.
2. Reply in writing: the company has to prove the car’s condition at pickup and return. Ask for the protocols, photos, inspection date, invoice and terms.
3. Challenge any flat fee under § 309 Nr. 5 BGB.
4. If a collection agency writes, dispute the claim in writing, demand the § 13a RDG information and sign nothing.
5. If your card was debited without your authorisation, tell your bank straight away.
