Should I send the arbitration claim email before or after filing through the portal?

File through the platform's arbitration portal first. The portal creates the official timestamped record. Send the email immediately after, referencing the portal claim number. At platforms without a portal, the email serves as the primary filing — send it within the filing window (10 calendar days at most North American platforms, 48 hours at BCA in the UK).

Can I send the same arbitration claim email to the seller directly?

You can send a copy to the seller as a courtesy, but file with the platform first. Most auction arbitration policies require the buyer to file through the platform. If the seller contacts you directly to negotiate, document the conversation and notify the arbitration department before accepting any settlement.

Auction Arbitration Claim Email Template

Q: What if the platform does not have a formal arbitration portal?

Use the email template as your primary claim filing. Send it to the platform's arbitration or operations email address and request written confirmation of receipt. Include every detail and attachment in the first message — you may not get a second opportunity to add evidence.

Q: What is the NAAA $800 disclosure threshold?

Under NAAA policy, sellers must disclose any known mechanical defect with a repair cost exceeding $800 at the NAAA wholesale labour rate. Defects below $800 are generally not arbitrable unless they involve frame damage, odometer discrepancy, title brands, or flood damage. Vehicles 20 model years or older are sold as-is and not eligible for mechanical arbitration.

Why a Professional Arbitration Claim Email Matters

Frame damage accounts for roughly 20% of wholesale arbitration claims, title issues represent 15%, and odometer discrepancies make up 12%. In each case, the outcome depends not on defect severity but on how clearly and completely the buyer documents the issue. A structured arbitration claim email creates the documentation trail that supports your portal filing and gives the arbitrator a clear, fact-based summary of the dispute.

Most platforms — Manheim, ADESA, and ACV Auctions — require formal filing through their arbitration portal. The portal creates the official record. Email serves a different purpose: it establishes a written communication trail with arbitrators, supplements the portal filing with narrative context, and provides the primary filing method for independent auctions that lack a dedicated portal. For a full overview of arbitration policy frameworks and filing procedures, see the Arbitration Claims Guide.

Before You Send

ADESA reviews only the issues described in the initial claim submission. Manheim assigns five calendar days per milestone to respond. ACV allows just two calendar days for evidence. Your first communication must be comprehensive — omitted defects and missing condition report references cannot be added later at most platforms. Confirm you have every item ready before composing the email.

Primary Claim Email Template

This template covers the most common arbitration scenario: an undisclosed mechanical defect. The subject line includes the claim reference number for traceability. The evidence list is numbered to match file attachments. The closing confirms the vehicle remains unrepaired — unauthorized repairs void arbitration rights at most platforms.

Arbitration Claim Email — Undisclosed Mechanical Defect

Subject: Arbitration Claim [CLAIM-REF-NUMBER] — Undisclosed Mechanical Defect — [YEAR MAKE MODEL] VIN [LAST 8 OF VIN] To: [PLATFORM ARBITRATION EMAIL / SELLER EMAIL] From: [YOUR NAME], [YOUR DEALERSHIP / COMPANY] Date: [DATE] VEHICLE DETAILS Year / Make / Model: [YEAR MAKE MODEL] VIN: [FULL VIN] Lot / Stock #: [LOT NUMBER] Purchase Date: [PURCHASE DATE] Hammer Price: [HAMMER PRICE] Total Paid (fees): [TOTAL INCLUDING BUYER FEE] Odometer at Sale: [LISTED MILEAGE] Odometer at Delivery:[DELIVERY MILEAGE] CLAIM REFERENCE Portal Claim #: [CLAIM-REF-NUMBER] Filed on: [FILING DATE AND TIME] ISSUE SUMMARY Upon delivery inspection on [DELIVERY DATE], the following undisclosed mechanical defect was identified: Defect: [SPECIFIC DEFECT DESCRIPTION — e.g., rod knock at idle, transmission slipping between 2nd and 3rd gear] Condition Report Status: Not disclosed in condition report section [SECTION NUMBER] dated [CR DATE] Discovery Method: [HOW DEFECT WAS FOUND — e.g., audible during initial inspection, identified during third-party diagnostic] The original condition report rated this vehicle [CONDITION GRADE] with no mention of [DEFECT TYPE] in the mechanical section. This defect existed at the time of sale and was not disclosed. EVIDENCE (ATTACHED) 1. Original condition report — [FILENAME] 2. Delivery photos with odometer and VIN — [FILENAME] 3.

Annotated diagram of an arbitration claim email showing the five required sections A professional arbitration claim email includes five structured sections that give the arbitrator everything needed to evaluate your case.

Three design choices in this template warrant explanation. First, the subject line includes the claim reference number so that every reply in the thread is traceable to the portal filing. Second, the evidence list is numbered to match the attached files — arbitrators review claims faster when attachments correspond to a clear index. Third, the closing confirms the vehicle remains unrepaired, which preserves your arbitration rights and demonstrates procedural compliance.

Template Variations

Each variation below replaces only the ISSUE SUMMARY and REQUESTED RESOLUTION sections of the primary template. All other sections — vehicle details, evidence list, vehicle status — remain the same.

Structural / Frame Damage

Variation: Structural / Frame Damage

ISSUE SUMMARY Upon delivery inspection on [DELIVERY DATE], structural damage was identified that was not disclosed in the condition report or listing: Defect: [SPECIFIC DAMAGE — e.g., bent rear subframe rail, prior repair to driver-side A-pillar] Frame Measurements: [MEASUREMENT DATA from certified body shop — e.g., 8mm deviation at left rear rail] Condition Report Status: No structural damage disclosed. Vehicle graded [CONDITION GRADE]. Inspection Facility: [CERTIFIED BODY SHOP NAME] (I-CAR Gold Class / manufacturer-certified) Note: Under NAAA policy, undisclosed structural damage is arbitrable even on Red Light (As-Is) vehicles when it exceeds the disclosure threshold. REQUESTED RESOLUTION The certified body shop estimates structural repair at [REPAIR AMOUNT]. Given the additional diminished value impact of documented frame damage, I am requesting [FULL RETURN / PRICE ADJUSTMENT OF AMOUNT] to reflect the undisclosed condition.

Frame damage remains arbitrable even on vehicles sold under Red Light (As-Is) designation when the damage was not disclosed. Include certified frame measurement data with specific deviation figures, not general descriptions.

Odometer / Mileage Discrepancy

Variation: Odometer / Mileage Discrepancy

ISSUE SUMMARY A mileage discrepancy was identified between the listed odometer reading and the vehicle's actual history: Listed Mileage: [MILEAGE ON LISTING / CONDITION REPORT] Actual Mileage: [ACTUAL MILEAGE per vehicle history report or physical evidence] Discrepancy: [DIFFERENCE] miles Source: [VEHICLE HISTORY REPORT PROVIDER] report and/or NMVTIS records Physical Evidence: [DESCRIBE — e.g., pedal wear, seat bolster wear, steering wheel condition inconsistent with listed mileage] Federal odometer law (49 USCS §32705) imposes penalties of up to three times actual damages or $10,000 per violation. REQUESTED RESOLUTION Given the confirmed mileage discrepancy, I am requesting a full return of the vehicle at the purchase price of [TOTAL PAID]. Odometer fraud warrants a complete return rather than a price adjustment, as the vehicle's true value cannot be determined with a falsified mileage record.

Mileage discrepancies warrant a full return request rather than a price adjustment. When the odometer reading is fraudulent, the vehicle’s actual condition and remaining service life cannot be accurately assessed.

Title Issue

Variation: Title Issue

ISSUE SUMMARY A title defect was identified that was not disclosed at the time of sale: Issue: [SPECIFIC TITLE PROBLEM — e.g., undisclosed salvage brand, undisclosed lien, rebuilt title not declared] Listed Title Status: [WHAT WAS REPRESENTED — e.g., clean title, no brands] Actual Title Status: [WHAT WAS FOUND — e.g., salvage brand per state DMV records, outstanding lien per title search] Verification Source: [STATE DMV records / NMVTIS / title search service] Note: ADESA allows 30 calendar days for title-related arbitration claims, compared to 10 days for mechanical defects. REQUESTED RESOLUTION I am requesting a full return at the purchase price of [TOTAL PAID]. The undisclosed [title brand / lien / status] materially misrepresents the vehicle and affects its wholesale and retail value.

Title claims operate under extended deadlines at some platforms. ADESA allows 30 calendar days for title-related claims. A salvage vehicle title brand that was not disclosed in the listing constitutes a material misrepresentation regardless of the vehicle’s physical condition.

Communication Tips

The language you use in claim emails directly affects how arbitrators evaluate your case. Specific, evidence-backed statements outperform vague complaints. Write as if the arbitrator has never seen the vehicle and has 15 minutes to review your case file.

Arbitrators evaluate claims based on specificity and evidence, not emotional intensity.
Element	Strong Claim Language	Weak Claim Language
Defect description	Rod knock audible at idle, confirmed by ASE-certified technician	Engine makes a noise
Evidence reference	See attached inspection report (Exhibit 3), page 2, findings section	I had it looked at
Cost quantification	$2,400 repair — 8 hrs at $90/hr labour + $1,680 parts	It will cost a lot to fix
Condition report reference	Section 4 of condition report dated Jan 10 lists engine as 'Good' with no disclosures	The condition report was wrong
Tone	Requesting price adjustment of $2,400 per attached estimate	This is unacceptable and I demand a refund
Resolution request	Price adjustment of $2,400 reflecting documented repair cost	I want my money back

When and How to Escalate

Most platform arbitration decisions are final and binding. Manheim, ADESA, and ACV Auctions all state this explicitly in their policies. However, limited escalation paths exist when you believe the process was not followed correctly or new evidence emerges.

Request a formal review from the arbitration department

Contact the platform's arbitration team in writing and cite the specific policy section you believe was misapplied. Include any evidence that was submitted but not addressed in the decision. Most platforms allow one review request within five business days of the ruling.

Escalate to platform management

If the formal review upholds the original decision, escalate to the regional or national arbitration manager. Reference your claim number, the review outcome, and the specific procedural concern. This is not a second appeal on the merits — focus on process errors.

File a complaint with NAAA

The National Auto Auction Association oversees arbitration policy standards for member platforms. File a written complaint documenting the timeline, evidence submitted, and the specific NAAA policy provision you believe was violated. NAAA does not overturn individual decisions but investigates systemic policy non-compliance.

Consult legal counsel

For claims involving federal violations — odometer fraud (49 USCS §32705, penalties up to 3x actual damages or $10,000), undisclosed salvage brands, or title fraud — consult an attorney specializing in automotive or commercial law. Legal action operates outside the platform's arbitration framework.

Frequently Asked Questions

Should I send this email before or after filing through the portal?

File through the platform’s arbitration portal first. The portal filing creates the official timestamped record and starts the formal review process. Send the email immediately after filing, referencing the portal claim number in the subject line. This gives the arbitrator both the structured portal submission and a narrative email trail. At platforms without a portal, the email serves as the primary filing — send it within the filing window (10 calendar days at most North American platforms, 48 hours at BCA in the UK).

What if the platform does not have a formal arbitration portal?

Use this email template as your primary claim filing. Send it to the platform’s arbitration or operations email address and request written confirmation of receipt. Independent auctions and smaller regional platforms often handle claims entirely via email. In these cases, the email is the official record, so include every detail and attachment in the first message — you may not get a second opportunity to add evidence.

Can I send the same email to the seller directly?

You can, but send it to the platform first. Most auction arbitration policies require the buyer to file through the platform, not directly with the seller. Sending a copy to the seller is acceptable as a courtesy and may prompt a faster resolution, but it does not replace the formal platform filing. If the seller contacts you directly to negotiate outside the platform, document the conversation and notify the arbitration department before accepting any settlement.

What is the NAAA $800 disclosure threshold?

Under NAAA arbitration policy, sellers must disclose any known mechanical defect with a repair cost exceeding $800 based on the NAAA wholesale labour rate. Defects below $800 are generally not arbitrable unless they involve frame damage, odometer discrepancy, title brands, or flood damage — these categories are arbitrable regardless of dollar amount. The $800 threshold applies to the wholesale repair cost, not the retail repair estimate. Vehicles 20 model years or older are sold as-is under NAAA policy and are not eligible for mechanical arbitration. For more on arbitration policy details, see the Arbitration Claims Guide.
