In this time of economic uncertainty, a part-time gig as an expert witness might provide helpful supplementary income. Almost anyone who has knowledge or training in a specialized field that exceeds the knowledge of most people has the potential to be an expert witness. At the same time, some people are more suited for the role of expert witness than others.
Individuals with degrees in engineering, accounting, psychology, and a variety of scientific disciplines regularly appear as expert witnesses. They explain or refute the economic and emotional losses claimed by plaintiffs. They analyze the likelihood that a defendant’s conduct did or didn’t harm a plaintiff. Medical experts testify about the nature and degree of injuries or disabilities.
In intellectual property cases, experts explain how a new invention or song is similar to or different from a patented invention or a copyrighted song. Experts in real estate valuation offer opinions about the value of real property. Experts in all kinds of personal property, from classic cars to comic book collections, offer opinions about the value of property that has been lost or damaged.
In criminal cases, expert witnesses who are employed by the government offer forensic or “criminalistics” testimony. The criminal defense bar employs experts to refute that testimony, often by pointing out the uncertain foundations upon which it is built.
Would You Be a Good Expert?
Not every field of expertise requires a degree. An auto mechanic who has serviced cars for many years might be well qualified to explain that a brake failure was the likely cause of an accident. An experienced roofer is well positioned to explain the cause of a leaky roof in a newly purchased home.
On the other hand, people often consider themselves to be experts despite having little more knowledge in a field than the average person. When experts in a field typically have specialized training, a court is unlikely to regard an expert as qualified in that field unless the expert can prove that he or she has the same training or experience that other members of the field commonly possess. Things do not go well for purported experts who try to fool a court by falsifying their credentials.
While specialized knowledge is essential, an expert witness must also be able to express that knowledge, both in writing and in testimony. In federal cases and in many state courts, a retained expert must prepare a written report. A witness who cannot prepare a report that states and supports opinions in clear language will have difficulty finding work.
Expert witnesses are often called upon to testify in depositions. Since most cases settle, they less frequently testify in court, but experts are sometimes called upon to give trial testimony. People who are nervous about speaking in front of a small group of people might not be good trial witnesses. People who are short-tempered or impatient will not respond well to cross-examination. Good expert witnesses have the ability to think on their feet, to answer complex questions in language that juries can understand, and to earn the respect of lawyers, judges, and juries by giving honest answers to difficult questions.
Expert Witnesses Are Not Hired Guns
Advocacy organizations that complain about “judicial hellholes” have tried to undermine the credibility of retained experts. To make it harder for plaintiffs to prevail in lawsuits against insurance companies and corporations, they have tried to spread the message that experts are “hired guns” who will say anything in exchange for a paycheck.
The truth is that most expert witnesses give honest opinions, whether they have been hired by a plaintiff or a defendant. They analyze the facts and arrive at conclusions that are supported by the evidence. While they are conscious of the goals a client hopes to achieve, they do not bend the truth to help a client win a case.
Experts who are “hired guns” in the sense that they offer unsupported or irrational opinions quickly lose credibility in the legal community. They become vulnerable to cross-examination. They risk having a judge reject their reports and bar their testimony because they offer opinions that no jury could regard as reasonable.
While expert witnesses can and should earn income by providing services to lawyers and their clients, the best motivation to become an expert witness is a desire to help jurors understand the facts of a case. Honest and ethical experts can enjoy a long and fruitful career as expert witnesses.
