Why Expert Testimony Is Critical in Property Insurance Litigation
Property insurance cases involving hurricanes, hail, wind, water, collapse, and large commercial losses often turn on expert testimony. The policy language and facts matter. But in many cases, the practical battle becomes a fight between experts.
Lawyers handling these cases have to do more than simply hire an engineer, contractor, building consultant, or cause-and-origin expert and hope the opinion holds up. The expert has to be selected carefully, prepared correctly, and supported by a reliable methodology. Just as important, the opposing expert’s assumptions, inspection methods, financial incentives, and litigation history must be tested.
A Recent Federal Court Ruling
A recent federal court ruling in one of our pending property insurance cases illustrates the point.
The case involves a commercial property that sustained significant hurricane damage. The insurance company and the policyholder reached very different conclusions about the scope of damage and the cost of repair. That is hardly unusual. In large property losses, the gap between what the insurance company says is owed and what the policyholder believes is necessary to restore the property can be enormous.
Our client retained an experienced forensic engineer to evaluate the building. The engineer and his team inspected the property over several days, including the roof, windows, doors, exterior walls, interior areas, and other building components. Because the property contained many similar components, the engineer did not inspect every single unit, window, or door. Instead, he used representative sampling.
What Is Representative Sampling?
Representative sampling is not guesswork. When done properly, it is an accepted engineering method used to evaluate large properties with repetitive components. A doctor does not need to test every drop of blood in the body to understand what a blood sample shows. In the same way, engineers may use a properly selected sample to evaluate conditions across a larger property when the components are similar, and the sampling method is reliable.
The Insurance Company’s Challenge
The insurance company asked the court to exclude the engineer’s testimony. It argued that the expert’s opinions were unreliable because he did not inspect every individual unit and every component. It also argued that some of the observed damage could have been caused by an earlier hurricane rather than the hurricane at issue in the case.
In other words, the insurer tried to keep the policyholder’s engineering expert and his opinions away from the jury and our proof of the case.
Why the Court Rejected the Challenge
The court rejected that argument. The judge found that the engineer used a reliable methodology accepted within the engineering profession. The court also noted that representative sampling is recognized in published engineering standards, including standards developed by the American Society of Civil Engineers.
The court further found that the engineer considered alternative explanations for the damage, including whether a prior hurricane could have caused the conditions he observed. The fact that the insurance company disagreed with the expert’s conclusions did not make the testimony inadmissible. Those disputes could be tested through cross-examination and competing expert testimony.
That is the way the system is supposed to work. Judges decide whether the expert used a reliable method. Juries decide what weight to give the testimony.
The Bigger Takeaway
The ruling is important, but not because it means the policyholder has won the case. The case remains pending. The jury will still have to decide the facts. The larger lesson is that expert testimony in property insurance litigation is not a side issue. It is often the center of the case.
Policyholders, condominium associations, commercial property owners, public adjusters, and restoration contractors should understand this. After a major storm, insurers often retain engineers and consultants who appear in claim after claim. Some of these experts have substantial experience. Some also have long histories of working for the insurance industry. That does not automatically make their opinions wrong. But it does mean their assumptions, methodology, scope of inspection, policy-language framing, and financial relationship with insurers deserve careful scrutiny.
Preparing Your Expert and Challenging the Other Side’s Expert
A good property insurance lawyer has to know how to prepare the policyholder’s expert before the fight begins. That means understanding what the expert inspected, what standards were followed, what documents were reviewed, what alternative causes were considered, and how the expert reached the final opinion.
It also means knowing how to challenge the opposing expert. Did the insurance company’s expert inspect enough of the property? Did the expert ignore damage inconsistent with the carrier’s position? Did the expert rely on assumptions instead of testing? Did the expert frame the opinion around policy exclusions rather than engineering facts? Has the expert repeatedly given similar opinions for insurers in other cases?
Those questions can matter as much as the policy language itself. Motions to exclude expert opinion are often described as technical legal motions about expert reliability. In property insurance cases, they are often much more than that. They can determine whether the jury ever hears the policyholder’s evidence and which party will win the case.
Final Thoughts
This recent ruling is a reminder that accepted engineering methods matter. So does preparation. So does knowing how to defend a qualified expert and how to expose weaknesses in the other side’s expert presentation.
In serious property insurance disputes, the expert battle is not an afterthought. It is a major part of the legal battlefield.
