What evidence does a garage keepers claim require?

This is general information, not legal or insurance advice. Forms vary by carrier and by state, and the only form that governs your claim is the one attached to your policy.

That is the opening line of the condition, not a preamble to it. It is the condition precedent that decides whether the rest of the policy applies at all — and the duties it introduces are mostly about evidence.

What evidence does garage keepers insurance require after a claim?

Garage keepers is an endorsement rather than a policy, so the duties sit one document further down than most shops look. ISO form CA 99 37 states that it modifies the Business Auto, Motor Carrier, and Truckers coverage forms, and that with respect to coverage provided by the endorsement, the provisions of the coverage form apply unless modified by the endorsement. It does not modify the duties after a loss, so they come from the underlying form. In ISO's Business Auto Coverage Form CA 00 01, Section IV.A.2 requires prompt notice stating how, when and where the loss occurred, the insured's name and address, and to the extent possible the names and addresses of any injured persons and witnesses. Where there is loss to a covered auto it additionally requires you to promptly notify the police if the vehicle or its equipment is stolen, take all reasonable steps to protect the vehicle from further damage and keep a record of what that cost, permit the insurer to inspect the vehicle and the records proving the loss before its repair or disposition, and agree to examinations under oath with a signed statement of your answers. The condition opens by saying the insurer has no duty to provide coverage under the policy unless there has been full compliance with those duties.

The chain of authority is three documents deep

Shops read the endorsement, find no claims procedure in it, and conclude their carrier will explain the process when the time comes. The endorsement itself says otherwise, in its own second paragraph.

• The endorsement — CA 99 37 10 01. Titled Garagekeepers Coverage, it opens: “This endorsement modifies insurance provided under the following: Business Auto Coverage Form, Motor Carrier Coverage Form, Truckers Coverage Form,” and then states that “with respect to coverage provided by this endorsement, the provisions of the Coverage Form apply unless modified by the endorsement” (independentagent.com). It goes on to define customer’s auto to include “any customer’s auto while left with you for service, repair, storage or safekeeping.”
• The coverage form — CA 00 01 03 10. Nothing in CA 99 37 modifies the duties after a loss, so they arrive unchanged from the form underneath. Section IV is titled Business Auto Conditions; A is Loss Conditions.
• The condition — Section IV.A.2. “Duties In The Event Of Accident, Claim, Suit Or Loss.” Paragraph a covers notice. Paragraph b covers conduct — do not pay, do not promise, forward the paperwork, cooperate. Paragraph c is the one written specifically for physical damage to a vehicle, and it is the one a shop has to be ready for before the loss rather than after it.

The other consequence of that chain is worth stating plainly: the deductible math and the per-location limit live in the endorsement, but the reason a claim gets paid or refused lives in the form. Which coverage basis you bought — Legal Liability, Direct Primary, or Direct Excess — is covered in the garage keepers guide. This page is about what happens after the phone call.

What does 'records proving the loss' actually mean?

The form never defines it, and that undefined phrase is where shops lose claims. CA 00 01 requires you to permit the insurer to inspect the covered auto and records proving the loss before its repair or disposition — the condition assumes those records already exist and says nothing about how to make them. An adjuster reconstructing a garage keepers loss is answering three questions: what condition the vehicle was in when it arrived, who had control of it and when, and what changed between those two points. A repair order answers the first badly and the other two not at all. Timestamped intake photos, an odometer reading captured at drop-off, a named custodian for every shift the car was on the lot, and a movement record for the visit answer all three.

Paragraph c.(3) is the whole reason this page exists. It asks the insured to “permit us to inspect the covered ‘auto’ and records proving the ‘loss’ before its repair or disposition.” Two things are doing work in that sentence. The first is records, plural and undefined. The second is before — the inspection right attaches to a vehicle in the condition it was in when the loss was discovered, which means the clock on preserving evidence starts before anyone has decided whether to file.

Can a shop just repair the damage itself instead of filing?

Read the condition before deciding. CA 00 01 Section IV.A.2.b.(1) says you must assume no obligation, make no payment and incur no expense without the insurer's consent, except at your own cost. A shop that quietly fixes a customer's bumper to keep the peace has done the thing the policy tells it not to do, and because paragraph c.(3) asks for inspection of the vehicle and the records before its repair or disposition, the same quiet fix can destroy the evidence the condition required. If the damage is small enough that you would rather absorb it than claim it, absorb it deliberately: tell your broker, document what you did, and understand you are paying out of pocket by choice rather than by accident.

Does garage keepers cover a customer car stolen by an employee?

No. CA 99 37 excludes loss due to theft or conversion caused in any way by you, your employees, or by your shareholders. That single exclusion is why the identity of whoever last had the vehicle matters to a garage keepers claim as much as the damage does — and it is the one place where a shop's own custody record can cut against it. A log showing a named employee took the car out at 11:40 PM is evidence, and evidence is not always exculpatory. Shops keep the record anyway because the alternative, having no answer at all when the accusation arrives, is worse far more often than it is better.

This is the honest half of the argument, and it belongs on the page rather than in a footnote. A custody record is not a shield. It is a record, and a record answers the question it was built to answer regardless of which way the answer points. What the reported shop-joyride cases show is that the shop is almost never the party holding one — the deciding evidence came from a factory data recorder, a customer’s dashcam, or a GPS app on the owner’s phone. That pattern, and the five cases behind it, is in the guide on a customer car damaged at your shop.

Does a clause in your own work order help?

It can push the loss outside the coverage. CA 99 37 excludes liability resulting from any agreement by which the insured accepts responsibility for loss, so a promise a shop writes into its own intake paperwork is a contractual obligation the garagekeepers endorsement does not answer for. The related exclusion is faulty work: the endorsement excludes faulty work you performed, and defines work you performed to include work someone performed on your behalf and the providing of, or failure to provide, warnings or instructions. Garage keepers pays for a customer's car being damaged in your care. It does not pay for the repair you got wrong, and it does not pay for responsibility you volunteered for in writing.

What happens if the shop and the insurer disagree on the amount?

Either side can force an appraisal. CA 00 01 Section IV.A.1 lets you or the insurer demand one: each party selects a competent appraiser, the two appraisers select a competent and impartial umpire, and a decision agreed to by any two is binding. Each party pays its own appraiser and the two split the umpire's expenses. The condition then ends with a sentence worth reading twice — if the insurer submits to an appraisal, it still retains its right to deny the claim. Appraisal settles the amount, not whether anything is owed. Separately, Section IV.A.3 bars anyone from bringing legal action against the insurer until there has been full compliance with all the terms of the coverage form, which points straight back at the duties in A.2.

How fast does a shop have to report a loss?

The form says prompt notice and puts no number on it. That is not leniency — it is a standard argued about after the fact, with the gap between the loss and the notice as the main exhibit. Treat the reporting deadline as the same day, and treat prompt as something you can prove with a timestamp rather than something you remember. The same applies to the police notification the form requires for a stolen vehicle: promptly notify the police is a duty, not a suggestion, and a report number is the cheapest evidence that will ever go in the file.

What the condition assumes you already have

Read Section IV.A.2.c as a specification rather than as legal text and it describes a file. A shop that can produce this file on the day of the loss is complying with the condition; a shop assembling it afterwards is reconstructing, and reconstruction is the thing an adjuster is trained to notice.

• Condition at intake, timestamped. Photographs taken before work started, plus the odometer reading at drop-off. This is what separates pre-existing damage from your damage, and it is the only part of the file that cannot be created later at any price.
• A named custodian, per shift. Not a key hook. A key hook records that a key existed. Paragraph b.(3) obliges you to cooperate in the investigation, and the first question in every investigation is who had it.
• A movement record for the visit. Miles driven, after-hours lot exits, charging sessions — counts and timestamps, bounded by the visit. This is the part that answers “what changed between drop-off and now,” and the part almost no shop has.
• The cost of protecting the vehicle after the loss. Paragraph c.(2) requires you to take all reasonable steps to protect the covered auto from further damage, and to “keep a record of your expenses for consideration in the settlement of the claim.” Tow, cover, secure storage, a battery tender — that is a reimbursable line only if someone wrote it down.
• A police report number, if anything was stolen. Paragraph c.(1) requires prompt police notification for a stolen covered auto or its equipment. Note that equipment is included, which on a modern vehicle covers more than most shops assume.

None of that is exotic, and none of it is what a shop management system produces. An SMS is the system of record for the job — estimates, parts, tech time, invoicing. The file above is the system of record for the car, and the two are not the same document. That distinction is argued at length on GuestLot versus shop management software.
