How an Expert Witness Can Strengthen Your Personal Injury Claim

On Behalf of | Sep 22, 2019 | Personal Injury

For most Floridians — and most Americans — the
legal system is too complex. Other than what we may have seen on TV or in
movies, most of us don’t really understand what happens in a courtroom,
particularly when it comes to civil cases. So, when we have the misfortune of
being involved in a personal injury case, we are even more stressed out by the
prospect of filing a lawsuit.

While filing a legal claim can be daunting, a
skilled attorney can shepherd you through the process. This includes gathering
evidence that will help support your case and get you the compensation that you

There are many different types of evidence that
can be used in a Florida personal injury case. For example, in a car accident
claim, a police report may be
used to demonstrate that the other driver was at fault for the collision.
However,  a police report is not
admissible in court.  Thus, there are
many other, more effective forms of evidence that can be utilized to prove a
claim, such as expert witnesses.

The Burden of Proof in Personal Injury Cases

Personal injury cases are based on a theory
of negligence, which is the failure of one party to use reasonable care to
avoid causing injury to another. The injured party, who is referred to as the
plaintiff, may suffer a range of damages, such as medical expenses, lost wages,
property damage, and pain and suffering.

When a plaintiff brings a personal injury
lawsuit, the burden of proof is on the Plaintiff to prove that the defendant
(the person or entity responsible for the accident) should be held responsible.
To do so, the plaintiff must prove the four elements of a negligence claim:
duty, breach, causation and damages.

Duty of care is the obligation that each of
us has to avoid injuring others or putting them in danger. A plaintiff must
show that a defendant had a duty of care based on the facts of specific case to
meet their burden of proof for this element.

Next, the plaintiff must prove that the
defendant breached their duty of care. This is shown by demonstrating that the
defendant either did or failed to do something that a reasonably prudent person
(an average person) would do under similar circumstances. For example, a
reasonably prudent person would not follow a car too closely in violation of
Florida law, so evidence that the defendant was following too closely at the
time of a car accident may be proof that they breached their duty of care.

The plaintiff then must show that the
defendant’s breach caused their injury. This is often a straightforward
requirement, such in dog bite cases: the dog bit you and you suffered deep
puncture wounds as a result. But in other claims, it may be more complicated,
like if you had a pre-existing injury — the defendant may argue that your
injury was pre-existing and not caused by the accident in question.

Finally, a plaintiff must prove their
damages. This will include any losses that you have suffered as a result of the
injury, which may include both special damages (out-of-pocket expenses that can
be quantified, such as lost wages) and general damages (more speculative
losses, such as pain and suffering). In rare cases, punitive damages are
awarded if the plaintiff can prove that intentional misconduct or gross
negligence occurred.

The Importance of Expert Witnesses

Learning the elements of a personal injury
claim is vital to understanding how expert witnesses can strengthen a personal
injury claim. Because the burden of proof is on the plaintiff to prove each
element of a negligence case, an expert witness may be necessary to bolster an
argument that a defendant had a duty of care to the plaintiff, breached that
duty, caused the plaintiff’s injuries, or that the plaintiff suffered certain

Under Florida’s evidentiary rules,
expert witnesses may testify at trial if scientific, technical or other
specialized knowledge will assist the jury or judge in understanding the
evidence or deciding a fact at issue in the case. A witness is qualified as an
expert based on their knowledge, skill, experience, training, or education. An
expert witness may be permitted to testify at trial if their testimony is based
on sufficient facts or data, is the product of reliable principles and methods,
and they have applied the principles and methods reliably to the facts of the

This rule is meant to ensure that experts
presented in court (in both civil and criminal cases) are legitimate, and that
they present their opinions based on sound reasoning. In other words, if a
proposed expert witness is a conspiracy theorist whose testimony lacks any sort
of evidentiary basis, then they will not be permitted to testify. This is
important, because expert witnesses should add clarity to the case and help the
judge or jury determine the truth of what actually happened — and whether the
defendant should be held responsible.

There are a number of different types of
experts that may be used in a personal injury case. Some experts consult with
attorneys to help explain important issues, while others testify at trial. In
any given personal injury case, the following expert witnesses may be utilized:

  • Medical experts: to
    testify or consult about the victim’s injury, their treatment, and prognosis
    • Mental health experts:
      to testify or consult about how the injury has impacted the victim’s mental and
      emotional state
    • Accident reconstruction
      experts: to testify or consult about how the accident happened using
      drawings, models and computer programs
    • Engineering experts: to
      testify or consult about the construction of a building or roadway and how it
      may have contributed to an accident
    • Manufacturing experts:
      to testify or consult about how a product was defective or improperly designed
    • Economics or financial
      experts: to testify or consult about how the injury has affected the
      victim’s financial status (lost earning capacity, etc.)

These expert witnesses can provide vital
information at any stage of a trial — or before trial — that will support a
plaintiff’s case. For example, a doctor may be able to testify about the extent
of a slip and fall victim’s injuries, as well as how the accident impacts the
victim’s ability to engage in daily activities. This testimony may be crucial
to proving damages.

In other cases, an expert witness may be called
to talk about industry standards. This may be particularly important to prove
duty of care, by showing that similar entities act in a certain way — and the
defendant in this case fell below that standard, breaching their duty of care.

While expert witnesses are often costly to
hire, they can provide crucial information and testimony. Depending on the
facts of the case, an expert witness may even allow your attorney to negotiate
a favorable settlement rather than having to take the case to trial. If your
case does go to trial, having one or more expert witnesses may be essential to
a successful outcome.
