Where we can help

We did the legal homework for ten countries.

For rentals in Germany, Austria, France, Italy, Spain, Portugal, Greece, Croatia, the United Kingdom and Switzerland we researched the law that decides these claims: who has to prove what, which contract clauses do not hold, what a company may actually charge, how you get money back from your card, and where free help exists. Every point checked against the official sources, re-checked every six months.

Damage claims, and the charges that arrive after return: fuel, cleaning, administrative fees, fines handling, card debits with no basis in the contract.

Works with every rental company in these ten countries. The current terms of Sixt, Europcar, Avis, Budget, Hertz, Enterprise, Goldcar, Centauro and 32 regional brands are already on file, so the letter quotes the clause they rely on; for any other company you upload your contract.

How it works

Rental companies count on you not reading their paperwork. We read all of it.

  1. 01, Upload
    Their claim. Your photos. Two minutes.

    Drop in the claim email, invoice, damage report and rental agreement, or forward the email to the case address every rental gets. Photos from the guided capture, or the ones already in your gallery: we read time and place from the files and sort them ourselves.

  2. 02, Forensics
    We verify what they hope nobody checks.

    Photo metadata and GPS on both sides. Dates that contradict each other. Fees above their own price list. Their current terms, read against the claim.

  3. 03, Send
    One letter that demands the evidence they don't have.

    In the language of the company, with the legal basis for the country you rented in, plus a chargeback kit for your bank and a step-by-step escalation plan. A person checks every letter before it reaches you. If they write back, forward it and get the grounded reply: same facts, same proof, same legal basis.

What we find

The same five weaknesses, claim after claim.

In consumer rental law the company must prove the damage happened during your rental. Most claims can't, and their own documents usually show why.

Why this exists

"I got a €1,320 invoice three days after dropping a key in a box. Being sure I hadn't damaged the car won nothing. Reading their own paperwork did, and the claim was gone in 24 hours. Then my sister-in-law got one. RentalProof is that method, for everyone."

  • Every legal citation verified against the primary source, nothing from memory.
  • Only arguments the evidence supports. We don't help anyone dodge damage they caused.
  • Not a law firm: software, forensics and documents. For the rare case that escalates, a partner lawyer takes over at a fixed price.
Next rental

Thirty seconds of proof beats an hour of arguing.

The RentalProof app guides you around the car at pickup and return. Every photo is timestamped and sealed the moment it's uploaded, so nobody can question when it was taken. If a claim ever comes, your evidence is already in the case: one tap opens the Dispute Kit, and we do the full forensics, the letter, the evidence pack and the chargeback file for you.

Behind it is extensive legal research: verified statutes and cases renters have won before, in Germany, Austria, France, Italy, Spain, Portugal, Greece, Croatia, the United Kingdom and Switzerland. We know how these claims are built, and where they fall apart.

One honest limit: proof only helps if the damage really was there before you drove off. It documents the truth, it does not create it.

Questions

Before you upload

Is this legal advice? Do I need a lawyer?

No, and most cases never need one. RentalProof is software: it reads your documents, verifies the evidence and generates the letter and files you send in your own name. That letter is what ends claims: the reference case was closed in writing within 24 hours of sending. A partner law firm exists for the rare case that escalates, at a fixed price. It is the exception, not the product.

Which countries?

Rentals in Germany, Austria, France, Italy, Spain, Portugal, Greece, Croatia, the United Kingdom and Switzerland. For each of them we did the legal research: what the law says on proof, on unfair clauses, on the amount and on card refunds, checked against the official sources. Rented somewhere else? Pick your country at the top and leave your email: the next country is chosen by demand, and the check tells you honestly when yours isn't covered yet.

They already charged my card.

Then the kit adds a chargeback file for your bank and a refund demand with statutory interest. Time matters here, card disputes have deadlines that run from the debit, not from when the company answers.

It is not damage. They billed fuel, cleaning, an "admin fee".

Same process. Each charge is checked on four points: was it in the contract you signed and stated clearly, does the clause hold up against consumer law, did you expressly agree to the extra, and can they prove the fact behind it, the fuel level, the dirt, the fine. The letter demands the refund with a deadline. The kit also explains the card route: a debit you never consented to can be reported to your bank up to 13 months after the debit, and the bank has to refund it.

Which rental companies?

Any. The check reads the documents you upload, whoever sent them. For Sixt, Europcar, Avis, Budget, Hertz, Enterprise, Goldcar, Centauro and sixteen regional brands we also hold their current terms, so the letter quotes the clause they rely on. For any other company, upload your contract and the terms you received at booking. RentalProof is independent and not affiliated with any rental company.

What if I actually caused the damage?

Tell us. The method still helps: we check whether the amount is fair, repair costs, fees, downtime, VAT, and never argue what the evidence doesn't support.

Can I just forward their emails?

Yes. Every rental in your account has its own address. Forward the company's emails there, attachments included; they are filed on the rental, the facts are read out, and the first one registers the claim by itself.

I took photos myself, without the app.

Add them from your gallery. We read the time and place inside each file, sort the photos onto the sixteen views of the guided capture and tell you which views are missing. Original files only; screenshots and messenger copies have lost their metadata.

What happens when the company writes back?

Forward their answer or upload the letter, then press one button. The reply answers each of their arguments with the proof and the legal basis, without moving from the first letter's position, and a person checks it before release. Every round works the same way.

Does it work for vans and transporters?

Yes. Vans bring their own claim pattern: a dented roof edge from a height barrier, scrapes on the load floor, a broken mirror, and terms that exclude some of this from the damage waiver so the deductible cap no longer applies. The capture app has a separate van walkthrough that records the load area, the roof edge and the mirrors, and the check reads those exclusion clauses against consumer law instead of taking them at face value.
