Insurance Expert is Not Allowed to Opine on Structural Design
Posted on May 13, 2025 by Expert Witness Profiler
Plaintiffs, Michael and Karen Green claimed that they had sustained loss as a result of hail and wind. Defendant Nationwide Mutual Insurance Company issued them a homeowner’s policy but when Plaintiffs filed a claim for loss under the policy, it gave rise to this dispute because Nationwide apparently failed to reimburse all covered losses under the Policy.
Nationwide sought to exclude the testimony of Plaintiffs’ retained expert witness, James Taylor, a licensed public adjuster.

Insurance Expert Witness
James Taylor has extensive knowledge about restoration and common practices in adjusting and handling claims in the insurance industry. He is licensed public adjuster, insurance appraiser, and IICRC-certified restorer with significant experience in insurance claims handling, loss assessment, and industry-standard compliance.
He has worked in field of remediation since 2000, and as an insurance adjustor and appraiser since 2019. Taylor’s professional background includes experience in water intrusion and hail damage assessments and structural loss analysis. He holds a public adjuster license with multi-state reciprocity, including Missouri, and maintains IICRC certification in restoration practices.
Discussion by the Court
Nationwide argued that Taylor lacked the qualifications to opine on the Nederveld engineering report or offer credibility opinions regarding third parties. Plaintiffs countered that Taylor’s testimony concerned insurance industry standards and claims handling practices, not legal conclusions, and agreed he would not testify on the legal standard for vexatious refusal to pay under Missouri law.
The Court found Taylor qualified based on his extensive experience as a public adjuster, appraiser, and restorer. The Court ruled that Taylor will be permitted to testify regarding insurance industry practices and standards in general, proper claims handling, how certain information affects claims decisions, and whether Nationwide’s actions deviated from insurance industry customs and practices.
As for the Nederveld engineering report, the Court allowed Taylor to testify on how the industry uses such reports and why, as an adjuster, he finds it reliable or not, but ruled he could not offer opinions on structural engineering defects. Similarly, while he could not give unfounded credibility opinions about third parties like SeekNow or Sedgwick Claims, the Court permitted him to testify if their services or practices were consistent with insurance industry standards.
Held
The Court granted in part and denied in part the Defendant’s motion to exclude the testimony of expert James Taylor.
Key Takeaway
Taylor is not an attorney offering a legal opinion as to whether Nationwide complied with Missouri law. He is a licensed public adjuster and former restorer, and he is an expert in insurance industry practices and standards. He is offering opinions as to whether Nationwide’s handling of Plaintiffs’ claim was in line with practices in the insurance industry, which goes to the issue of reasonableness and is admissible.
