Selecting a Financial Expert: A Checklist for Litigators

by Mark S. Gottlieb, CPA/ABV/CFF, ASA, CVA, CBA

April was a blur. I spent the month moving between depositions and trial testimony on several high-stakes matters, and the days ran together the way they do when the calendar refuses to cooperate. Now that the dust has settled, four specific traits stand out as the clear difference-makers between an expert who truly impacts a case and one who is just filling a seat on the witness stand.

This one is for the lawyers and litigators who hire us. If you are choosing an expert, evaluating an opposing one, or preparing your own for testimony, the items below are what I would put on your checklist.

1. Independence and Objectivity

Let me say this plainly: the expert works for the analysis, not the party who paid the retainer.

That sentence sounds obvious until you watch what happens when an expert forgets it. The numbers start migrating toward the desired conclusion. Adjustments appear which have no defensible basis. By the time cross-examination begins, the expert is no longer credible, and the testimony, however technically correct in places, becomes a liability for the attorney who hired him.

An expert should examine the same facts with the same rigor regardless of who is paying. It also means telling the retaining attorney early, and clearly, when the analysis does not support the theory of the case. That conversation is uncomfortable. It is also the conversation that protects the case, because an expert who will not have it in your office will eventually have it on the stand, with opposing counsel asking the questions.

Courts notice this, too. Daubert challenges and motions in limine increasingly probe the methodology and the independence behind the analysis. Objectivity is what makes the rest of the work hold together.

2. Methodological Rigor and Adherence to Professional Standards

Financial litigation is a discipline with rules. AICPA SSVS No. 1, USPAP, NACVA standards, and IRS Revenue Ruling 59-60 exist for a reason. They give the work a common structure, a shared vocabulary, and a measurable benchmark.

An effective expert follows the standards, documents the work, and shows it. The workpapers should tell the story: what was reviewed, what was relied on, what was excluded and why, which approaches were considered and applied, and how the final conclusion was reconciled. A second expert applying the same standards to the same data should arrive in the same neighborhood. If a competent practitioner cannot replicate the path, the conclusion is not defensible, no matter how confident the expert sounds.

Rigor also means resisting the temptation to be clever. Litigation is not the place to debut an exotic technique. Use accepted approaches, accepted data, and accepted sources. When a departure from convention is necessary, document the reason, and be ready to defend it.

The shorthand version: if you cannot show your work in a way another professional can audit, you do not really have an opinion, but rather a guest wearing a suit.

3. Clarity and Communication Skills

A valuation report or a damages analysis is, at its core, a translation exercise. The expert is taking financial concepts that took years to learn and explaining them to people (judges, juries, opposing counsel) who do not share that training and do not need to.

Clarity is not dumbing the material down. It is finding the through line. A well-prepared expert can explain a discounted cash flow analysis in two minutes using language a smart non-accountant will follow. The same expert, asked the same question on direct, can give a five-sentence answer that the trier of fact retains.

A few habits separate the experts who do this well from the ones who struggle:

  • They use plain words. Goodwill is the value of a customer relationship that walks back through the door tomorrow, not an “intangible economic benefit attributable to enterprise reputation.” The first version teaches. The second version tests the patience of the bench.
  • They use exhibits sparingly and well. One clean chart often does more work than three pages of text. The exhibit should answer a question, not raise new ones.
  • They know when to stop. The expert who keeps talking after the question is answered is the expert who hands opposing counsel the next thirty minutes of cross.

If the judge cannot follow you, the analysis loses, even when the analysis is right.

4. Credibility Under Cross-Examination

Cross-examination is where everything else gets tested. Independence, rigor, and clarity all come together (or fall apart) in the exchange across the courtroom.

The credible expert is prepared. He knows the file cold, including the unflattering parts. He has anticipated the awkward questions and has thought through honest answers, not clever ones. He has reread his report, his deposition transcript, and the key documents the night before.

He is also composed. He does not argue with opposing counsel. He does not get defensive. He answers the question that was asked, not the one he wishes had been asked. When the right answer is “I do not know,” he says so.

What undermines credibility is almost always the same handful of things: overstating certainty, treating cross-examination as a personal contest, refusing to acknowledge a reasonable alternative view, drifting into advocacy. Each of those moments gives the trier of fact a reason to discount the testimony, and once that discount starts, it rarely stops.

Credibility, in the end, is the cumulative impression of a person who is doing the work honestly and saying only what the work supports.
