Lawyers' Professional Liability

On April 15, 2026, the New Jersey Appellate Division issued an important decision in Gonzalez v. DiBello, et al., A‑2334‑24 (App. Div. Apr. 15, 2026), affirming summary judgment in favor of a transactional attorney accused of legal malpractice and breach of fiduciary duty. Marshall Dennehey’s Jack Slimm and Jeremy Zacharias successfully represented the attorney‑defendant. The decision provides significant guidance to both the malpractice defense bar and transactional practitioners, particularly regarding the scope of an attorney’s duty of care, the role of expert testimony, and the proof required to establish causation and damages.

The malpractice action stemmed from an underlying federal lawsuit arising out of a failed transaction to purchase a Kia dealership. An investor alleged that the purchasers and their counsel engaged in a fraudulent scheme, asserting claims including fraud, breach of contract, breach of fiduciary duty, aiding and abetting, and conspiracy. Although the federal complaint named the transactional attorney, the claims against her were dismissed, and she was never found liable. The attorney neither represented the investor nor provided him with legal advice and was unaware that he was the ultimate source of investment funds. Her role was limited to preparing transaction documents required by the manufacturer to reflect a transfer of ownership interests.

Following dismissal of the federal action, purchaser Christopher Gonzalez filed a legal malpractice and breach of fiduciary duty action against the attorney. Gonzalez relied on expert reports asserting that the attorney had a duty to investigate the source of funds, determine whether her client was financially capable of consummating the transaction, and uncover any disqualifying relationships among investors. The trial court rejected those opinions, holding that New Jersey law does not impose upon transactional attorneys a duty to investigate the origins of funds passing through a trust account or to assess a client’s financial capacity absent specific circumstances. The Appellate Division affirmed, reiterating that an attorney’s duty in a transaction is “to exercise that degree of reasonable knowledge and skill that lawyers of ordinary ability and skill possess and exercise,” and that alleged violations of the Rules of Professional Conduct do not, standing alone, create a cause of action.

The Appellate Division also affirmed dismissal based on the plaintiff’s failure to establish damages and causation through competent expert testimony. Gonzalez sought, among other things, to recover all legal fees incurred defending the federal action and alleged loss of investment. However, his expert offered what the courts deemed a classic “net opinion,” failing to analyze the reasonableness of the fees, allocate which fees were allegedly caused by the claimed malpractice, or quantify any lost benefit of the bargain. The court emphasized that when damages are an essential element of a legal malpractice claim, expert testimony must do more than assert conclusions—it must explain how and why specific damages were proximately caused by the attorney’s conduct. Absent such an analysis, allowing a jury to award all defense fees would impermissibly convert compensatory damages into speculative or liquidated damages.

Finally, the Appellate Division rejected Gonzalez’s attempt to salvage his claims through a “suit‑within‑a‑suit” theory or a parallel breach of fiduciary duty claim. Citing Morris Properties, Inc. v. Wheeler, the court reaffirmed that plaintiffs cannot avoid their prima facie proof requirements by invoking trial methodologies, and that expert testimony remains necessary in esoteric malpractice cases. The court further held that Gonzalez could not show he would have recovered in the underlying federal action, particularly where he and the attorney were dismissed from that case. The fiduciary duty claim was properly dismissed as duplicative of the malpractice claim and failed for the same lack of proof on causation and damages.

This decision is a significant reaffirmation of rigorous proof standards in transactional malpractice cases and provides meaningful protection against expansive and speculative damages theories.
