Expert Witness Defined
An expert witness is hired to provide independent expertise on any subject in a court of law. Expert witnesses can be used in various capacities like arbitrations and litigations. These witnesses will give sworn evidence to a court of law or tribunal.
There are two types of expert witnesses:
- Witness who gives evidence based on his/her expertise related to the facts of a specific case.
- Witness of fact who provides evidence, but generally refrains from giving opinions.
Anyone with knowledge or expertise in a field of interest can become an expert witness. The main duty of any expert witness is to provide the court with unbiased expertise and opinions related to the case. These experts are called upon to help decide disputes. Typically, witnesses are not used to assist in the formation of a party’s claim or defense, though. Testimonies by these witnesses can ultimately swing juries and win cases. Expert witnesses will always be compensated by the team retaining them.

Benefits Of Expert Witness Testimony
The benefits a well-chosen expert witness provides to a case aren’t all apparent at first glance. Here’s why expert witnesses are important – and why selecting the right expert is vital. Popular images of “experts” often include people who make their living at a particular practice or topic, or who have written a book on the subject. Yet legal standards for experts don’t require that expert witnesses meet either of these standards.
This flexibility can be of great use to attorneys. The central issue in some cases is so narrow and fact-specific that no one makes their living by focusing solely on that particular issue. At the other end of spectrum, some cases present issues that cannot be fully understood unless their impact in several different domains is explored. For example, establishing the full impact of chronic pain after a car accident may require attorneys to explore several different areas of medicine, including neurology, orthopedic medicine, physical and occupational therapy, and psychiatry or psychology
Preparing a lay witness to testify is often a matter of ensuring they understand the basic boundaries of lay testimony. Experts are educated and/or trained in their particular specialty area, they can take what they know and build on it. Because they have the opportunity to objectively interpret the facts from using a variety of methods, experts can develop a cogent analysis of the liability on which to base their testimony.
Can Anyone Become An Expert Witness?
If you are wondering if any professional can become an expert witness, the answer is yes. In fact, nowadays many nurses, doctors and paramedics are commonly called for services during cases. These professionals are called to provide expertise on injuries, medical procedures, etc. Many other professions can be in high demand, as well. For example, contractors and architects are used to provide insight on building codes and construction practices, among other topics. Teachers can be requested in cases regarding education.
These are the legal expectations for all expert witnesses:
- Agree contractual terms with the expert in writing before the work is started. These will include terms of payment. Many experts use standard terms such as The Academy of Experts ‘Model Terms of Engagement For The Employment of Experts.’
- Provide detailed instructions.
- Keep the expert informed of developments in the case and of all key dates in good time.
- It is better that the legal representative, if you have one, deals with the Expert rather than you doing so.
Expert Witness Legal Standards
There are no “hard and fast” rules or regulations for expert witnesses today. Instead, attorneys and judges rely on two monumental court opinions when determining whether or not a witness is qualified for the case. Frye Vs. The United States essentially established standards for expert witnesses. The ruling in the case stated that any witness testimony must be widely accepted within the scientific community.
A different case, Daubert Vs. Merrill Dow Pharmaceuticals, Inc., resulted in a more modern set of standards. As long as the witnessed used scientific methods, peer-reviewed methodology and shared an opinion that was widely accepted, the expert’s opinion would then hold up in court. The Daubert case essentially gave judges the power to determine validity of any expert testimony.
When Are You Officially An Expert Witness?
There are several ways to become recognized as an expert witness either through extensive education or job-related experience. Typically, there are a few guidelines that hold true in the majority of cases utilizing their services. Witnesses ideally hold a terminal or advanced degree in their professional field. In some cases, a long and successful career can outweigh academics, though.
Attorneys determining the validity of an expert witness will examine these areas:
- Have you at any time been quoted by the press?
- Have you spoken at any professional conferences?
- How flexible is your current schedule?
- Have you ever won a prestigious award?
- Is any work of yours published in highly-regarded journals?
- Do you have any prior witness experience?
- Are you comfortable and able to communicate during court proceedings?
Lay Witness Testimony
Generally speaking, the law divides witnesses into two categories: Fact Witnesses and Opinion Witnesses. Fact witnesses, or lay witnesses, testify about their firsthand knowledge: what they heard, saw, said, or did. Fact witnesses are often closely related to the case in some way. They may be family members, business partners, or eyewitnesses at the scene.
Lay witnesses are typically restricted to testifying about things they personally perceived and about which the average reasonable person could also form an opinion. For instance, a lay witness to a car accident might testify that she saw the defendant’s car run a red light at a high rate of speed, and that as a result, her opinion was that the driver was speeding.
Federal Rule of Civil Procedure 26(a)(2) (and similar rules in many states) requires lawyers to meet disclosure requirements for expert witnesses above and beyond those required for lay witnesses.
Rule 26(a)(2) requires retained experts to submit an expert report if they will testify. Non-testifying experts may also be required to be disclosed or to submit a report in certain circumstances. When they do not, their work is generally considered protected by attorney work product rules.
By contrast, lay witness opinions generally do not need to be summarized in a report or otherwise disclosed prior to trial. When a lay witness’ testimony approaches the line between lay observations and expert opinions, however, lawyers may need to consider ways to ensure the testimony remains usable at trial. Typically, lawyers have two options. The first is to disclose the lay witness’ opinion. The second is to reach an agreement with opposing counsel regarding the precise disclosures required.
