Most vehicle appraisals submitted in legal matters are never challenged. The report goes into the file, the parties agree on a number, and the case resolves. But when an appraisal does get challenged — in a deposition, a Daubert motion, or at the bench — the appraiser who signed it needs to be able to defend every number, every comparable sale, and every methodological choice they made.

This post is for attorneys who are considering engaging us for testimony, or who want to understand what a vehicle appraiser can and cannot do in a legal proceeding before they commit to a hearing date that depends on it.

What gets challenged and how

When opposing counsel challenges a vehicle appraisal, they are usually attacking one of three things:

The appraiser's qualifications. Who is this person? What certifications do they hold? Have they testified before? What is their methodology? This is why the appraiser qualifications page matters — not as a formality, but as the first line of defense against a qualifications challenge.

The comparable sales. Which sales did you use? Why those and not these? How did you account for condition differences between the comparable and the subject vehicle? A well-documented appraisal has answers to all of these questions in the report itself — not in the appraiser's memory.

The condition assessment. How did you determine the vehicle was in #2 condition and not #3? What did you observe? If the appraisal was photo-based, what were the limitations of that method and how did you account for them? If it was on-site, what did you find?

An appraiser who cannot answer these questions under oath is a liability. An appraiser who can answer them — because the methodology is documented and the report is built to survive scrutiny — is an asset.

What a declaration looks like

A written declaration is the most common form of testimony we provide. It is a sworn statement that sets out the appraiser's qualifications, the methodology used, the comparable sales relied upon, and the value conclusion — in a form that can be submitted to the court without requiring the appraiser to appear.

A declaration is appropriate when:

• The appraisal is being submitted in support of a motion or as a court exhibit
• The matter is unlikely to proceed to a contested hearing
• The parties want a sworn statement that is harder to dismiss than an unsworn report

A declaration is a separate written engagement from the appraisal itself. It requires its own agreement, its own scope, and its own fee. We do not produce declarations as a free add-on to an appraisal — they take time to prepare correctly, and a declaration that is not prepared correctly is worse than no declaration at all.

What a deposition looks like

If opposing counsel deposes the appraiser, the deposition will cover the same ground as a declaration — qualifications, methodology, comparable sales, condition assessment — but in real time, under cross-examination, with follow-up questions.

The things that make a deposition go well:

The report is complete. Every methodological choice is documented. Every comparable sale is in the report with the appraiser's reasoning for using it. The condition assessment is specific, not generic. There are no gaps that opposing counsel can exploit.

The appraiser knows the vehicle. Not just the report — the vehicle. What makes this particular car valuable or not valuable. What the market for this type of vehicle looks like. What a buyer and seller would have agreed to on the effective date.

The appraiser can explain the methodology in plain English. A judge or mediator is not a car person. The appraiser needs to be able to explain why a numbers-matching engine matters, what a Bloomington Gold certification means for value, and why the comparable sale from a private transaction is more relevant than the one from a dealer auction — without losing the room.

We have been doing this for 35 years. We know the vehicles we appraise, and we can explain our methodology to a non-specialist audience.

What a Daubert challenge looks like

In federal court and in many state courts, expert testimony is subject to a reliability standard — the court acts as a gatekeeper and decides whether the expert's methodology is sufficiently reliable to be admitted. For vehicle appraisers, a Daubert challenge typically attacks:

• Whether the appraiser used a recognized methodology (USPAP compliance matters here)
• Whether the methodology was applied correctly to the facts of the case
• Whether the appraiser's qualifications support the opinions they are offering

A prepared in substantial conformity with USPAP report from a certified appraiser is not immune to a Daubert challenge, but it is in a much stronger position than an informal letter or a price guide printout. The methodology is documented. The qualifications are in the report. The comparable sales are cited.

What to discuss before you engage us for testimony

Before you commit to a hearing date that depends on our testimony, there are things we need to discuss:

Availability. We are not full-time expert witnesses. We appraise vehicles across all 50 states, and our schedule is not always open on the date you need. Confirm availability before you set the date.

Scope. What are you asking us to testify about? The value conclusion? The methodology? The condition of the vehicle? The scope of the testimony engagement needs to be defined before we agree to it.

The report. If we are being asked to testify about an appraisal we did not write, we need to review it first. We will not testify to a methodology we did not use or a value conclusion we cannot defend.

Fee. Testimony is billed separately from the appraisal. The fee depends on the scope — declaration, deposition, or trial — and the time required. We give a clear number before you commit.

What we will not do

We will not testify to a value we cannot defend. If the number in the report is wrong — because the effective date was wrong, because the comparable sales were cherry-picked, or because the condition assessment was inaccurate — we will not go into a deposition and defend it.

We will not agree to a hearing date and then tell you two weeks out that we are unavailable. If we say yes, we mean it.

We will not produce a declaration that is designed to obscure the methodology rather than explain it. A declaration that cannot survive cross-examination is not worth the paper it is printed on.

What to send us

To discuss a testimony engagement:

• The appraisal report (if we wrote it) or the report you want us to review (if we did not)
• The nature of the proceeding — declaration, deposition, or trial
• The hearing date or deadline
• The jurisdiction

Call or text (270) 790-7534. We will tell you on the first call whether we can help and what it will cost.
