When is expert testimony required in Utah legal malpractice cases? Kendall v. Utah Estate Planners Explained

The Utah Court of Appeals in Kendall v. Utah Estate Planners addressed a critical question for legal malpractice practitioners: when must plaintiffs present expert testimony to establish an attorney’s breach of the standard of care? The court’s ruling provides important guidance on this evidentiary requirement.

Background and Facts

Trust co-trustees sued their former attorney, alleging legal malpractice related to improper advice about trust distributions and conflicts of interest. The claims involved complex allegations concerning sub-trusts, minimum distributions from IRAs under federal law and the Utah Principal and Income Act, and alleged dissipation of trust assets over many years. When trustees failed to designate an expert witness on the attorney standard of care, the defendant moved for summary judgment.

Key Legal Issues

The case presented two main issues: (1) whether a different standard of review applies for expert testimony requirements in legal malpractice cases tried to the bench versus jury trials, and (2) whether the alleged attorney misconduct was sufficiently obvious to lay persons to proceed without expert testimony.

Court’s Analysis and Holding

The court rejected trustees’ argument that bench trials should apply a more lenient standard for expert testimony requirements. Following decisions from other jurisdictions, the court explained that judges acting as factfinders cannot rely on their own legal knowledge and must base decisions on evidence presented at trial. The same standard applies regardless of whether the case is tried to a bench or jury.

Applying the established standard, the court held that expert testimony is required unless the attorney’s conduct “is within the common knowledge and experience of the layman.” The court found the allegations too complex for lay understanding, involving intricate trust law, federal IRA distribution requirements, and professional conduct rules.

Practice Implications

This decision reinforces that legal malpractice plaintiffs must carefully evaluate whether expert testimony is necessary early in litigation. The “obvious misconduct” exception applies only in clear cases like theft of client funds or missing obvious deadlines. For complex professional duties involving specialized areas of law, expert testimony remains essential regardless of the trial format. Practitioners should designate qualified experts during discovery deadlines to avoid dismissal on summary judgment.
