Can unclear law defeat causation in Utah legal malpractice cases? Iacono v. Hicken Explained

In Iacono v. Hicken, the Utah Court of Appeals addressed a fundamental question in legal malpractice litigation: when can an attorney’s admitted breach of duty still result in no liability due to lack of causation? The case provides important guidance for practitioners on the causation element in malpractice claims and the role of unsettled law in defeating such claims.

Background and Facts

Julie Iacono’s father created a family trust that became irrevocable upon either parent’s death. After her mother died, her father attempted to amend the trust to give his Ogden home specifically to Iacono rather than dividing it among all four children. When Iacono’s siblings challenged this amendment after their father’s death, attorney Bret Hicken represented Iacono but provided what the court found to be substandard representation. Hicken failed to conduct discovery, assert defenses, or cite relevant case law. The district court granted summary judgment for the siblings, ruling the trust amendment invalid.

Key Legal Issues

Iacono sued Hicken for legal malpractice, claiming his inadequate representation caused her to lose the trust litigation. The central issue was whether Hicken’s admitted breach of the standard of care caused Iacono’s damages, particularly given that the law on trust amendability was unclear at the time of the underlying case.

Court’s Analysis and Holding

The Court of Appeals affirmed the district court’s finding of no causation. While acknowledging Hicken breached his duty of care, the court emphasized that Iacono had to prove she would have achieved a better result with competent representation. The district court properly reviewed the cases Iacono’s expert claimed Hicken should have cited—West v. West, Clayton v. Behle, and Kline v. Utah Department of Health—and determined they would not have clearly established the trust’s amendability. The court rejected Iacono’s argument that expert testimony was required to establish causation, noting that when causation depends on legal interpretation, it presents a question of law for the court.

Practice Implications

This decision reinforces that breach of duty alone is insufficient in legal malpractice cases—plaintiffs must establish both actual and proximate causation. When the underlying legal question involves unsettled law, proving causation becomes particularly challenging. The case also clarifies that courts may independently review legal authorities cited by experts and are not bound by expert opinions on questions of law. For malpractice plaintiffs, the decision highlights the importance of demonstrating concrete ways that competent representation would have led to different legal outcomes, not merely speculative possibilities.
