Part 12: Taking the Stand - How our Damage Experts Present the Financial Story
Everything in this series has been building to this moment: The witness stand.
The Expert's Role at Trial
It is worth stepping back for a moment to put the damages expert's role in context. Economic damages are important, but they are one piece of a much larger story that the trier of fact is being asked to piece together. There are fact witnesses, other expert witnesses, documentary evidence, and legal arguments all competing for the attention and understanding of a judge or jury.
The damages expert is most often the last witness to testify. By the time they take the stand, the trier-of-fact has already been presented with a significant amount of information. The expert's job is to take all of that context, connect it to the financial analysis, and deliver a clear, credible opinion that the trier-of-fact can actually use in their deliberations.
That is harder than it sounds.
The Value of Being in the Courtroom
Being present in the courtroom before taking the stand gives a damages expert something preparation alone cannot provide: the ability to hear what other witnesses are actually saying, to observe the demeanor of opposing counsel, and see how the jury is responding amidst all the proceedings.
Listening to fact witnesses, the opposing expert, and other experts as they testify allows the damages expert to understand how the evidence is being framed in real time, which may differ from what was in the reports and depositions. It also allows the expert to help counsel in the moment as testimony unfolds, flagging financial issues or inconsistencies as they arise before it is too late to address them.
Communicating Complex Analysis to a Non-Financial Audience
The single biggest challenge of expert testimony in a damages case is translating a complex financial analysis into something that a judge or jury, without a financial background, can clearly follow and understand.
This is not about dumbing things down. It is about finding the right level of explanation, the right analogies, and the right sequence of information to make the analysis accessible without sacrificing accuracy. An expert who speaks in accounting jargon, who assumes the jury understands technical financial terminology, or who presents a model without explaining what it is designed to measure, is an expert who has lost the room.
The best damages experts are teachers as much as they are analysts. Their job at trial is not just to present conclusions but to bring the trier-of-fact along for the reasoning that led to those conclusions.
Know Your Audience
How a damages expert communicates at trial depends significantly on who is listening. A bench trial and a jury trial are very different environments and require different approaches.
In a bench trial, the trier-of-fact is a judge who likely has a sophisticated understanding of legal and evidentiary standards. Even though judges rarely have a deep financial background they have usually heard enough cases involving accounting or financial concepts that they can sometimes track with more of what the expert is testifying about. The testimony can be somewhat more technical and the expert can move through the analysis at a little faster pace without losing the room.
In a jury trial, the calculus shifts. Jurors bring a wide range of backgrounds and experiences to the box, and the expert's job is to meet them there. That means communicating with clarity and intention — translating complex financial concepts into language that is accessible without being reductive. The goal is not to showcase the sophistication of the analysis. It is to make it understood.
Demonstratives
Demonstratives are one of the most powerful tools available to a damages expert at trial. A well-designed chart or summary exhibit can communicate in seconds what would take minutes to explain verbally. They give the jury something to look at, something to anchor the testimony to, and something they may be able to refer back to during deliberations.
The key is keeping them simple. A demonstrative that is too dense or too technical defeats the purpose. The goal is clarity. A single chart that clearly shows the difference between actual and but-for revenue is worth more than a complex exhibit that loses the jury before they understand what they are looking at.
Preparing counter demonstratives in anticipation of the opposing expert's testimony is also worth the effort. If you know what the other side is likely to show the jury, having a visual response prepared can be helpful for the trier-of-fact.
Objectivity and Credibility
One of the most important qualities a damages expert can bring to the witness stand is genuine objectivity. A jury can tell the difference between an expert who has reached an independent conclusion and one who is advocating for the side that hired them. The former is credible. The latter is not.
That does not mean an expert cannot be confident in their opinions. It means the confidence has to be grounded in the analysis, not in loyalty to or advocacy for the client. It is said, an expert should be an advocate for their analysis and opinions, not an advocate for the party who hired them. That is the attorney’s job. An expert who acknowledges the limitations of their analysis, who does not overreach in their conclusions, and who treats the opposing expert's work fairly even while disagreeing with it, is an expert whose testimony carries weight.
Handling Cross Examination
Cross examination is another area where extensive preparation pays off. Opposing counsel will probe the methodology, challenge the assumptions, look for inconsistencies between the expert's testimony and their report, and generally try and poke holes in the opposing expert’s analysis. A well-prepared expert stays calm under pressure and responds with the same measured precision under cross as they do on direct. That consistency is what makes testimony credible and hard to undermine. A concise, direct answer is almost always more effective than a long one.
A Note on Where This All Leads
This series has covered a lot of ground. From the moment a damages expert is retained to the moment they step off the witness stand, there are dozens of decisions, analyses, and collaborations that shape the outcome of a damages case.
The connecting theme across all of our blog series is this: the earlier and more significantly a damages expert is integrated into the case, the more complete and well supported the analysis will be at every stage of the process.
