Legal Updates for Lawyers' Professional Liability

Delaware Superior Court Dismissed Plaintiff’s Legal Malpractice Claims Because He Failed To Identify an Expert Witness Who Would Support His Claims at His Forthcoming Jury Trial.

In Weiner v. Holfeld, 2021 WL 5577255 (Del. Super. Ct. Nov. 30, 2021), the plaintiff claimed that expert testimony was not necessary because the matter at issue involved obvious common sense and public knowledge. The Superior Court, however, held: “[e]ven if Defendant's alleged mistakes were deemed ‘obvious’ or matters of common sense, an expert's opinion would still be necessary to clarify (1) what damages were caused by the Defendant's inadequate representation; (2) if and how the Plaintiff's conduct should factor into any award of damages; and (3) whether the Defendant's alleged inadequate representation was the proximate cause of the Plaintiff's damages. Because these matters are not the type ‘that a layman, exercising his common sense, [would be] perfectly competent to determine[,]’ an expert's opinion is required.”

The court’s conclusion is interesting in that it would be very difficult to find circumstances where an expert’s testimony would not be required in a legal malpractice case arising from litigation. For example, it may be obvious that an attorney failed to file a complaint before the expiration of the applicable statute of limitations. Expert testimony, however, would be required to demonstrate the extent of any damages; whether the plaintiff contributed to the failure to timely file a complaint; and whether the plaintiff would have prevailed in the underlying action if a complaint had been timely filed.

Appellate Division Affirms Dismissal of Legal Malpractice Counterclaim Against Martin Law Firm

In Martin v. Loury, 2026 N.J. Super. Unpub. LEXIS 1617 (App. Div. July 15, 2026), Martin Law Firm represented Kirk Loury in an employment matter Mr. Loury filed against his former employer, Concord Equity Group Advisors LLC (“Concord”). The allegations included, among other things, that Loury was not fairly compensated for his employment with Concord. After a bench trial finding in Loury’s favor, the Appellate Division remanded this matter in February 2016 for a second trial. During the second trial, Concord CEO, Lee Argush, testified to lower compensation estimate than first trial. On remand, the second trial judge awarded Mr. Loury the same damages as the first judge, finding Mr. Argush not credible. After the findings during the second trial, Martin Law Firm filed an action against Mr. Loury to recover legal fees and costs of representing Mr. Loury in a second bench trial and Mr. Loury filed a counterclaim against Martin Law Firm for legal malpractice, alleging he should have received an even higher award in the second bench trial. In this allegation, Mr. Loury, through his expert, claimed that Martin Law Firm should have recalled Mr. Loury to the stand to rebut Mr. Argush’s testimony to allege an alternative theory of damages. Mr. Loury’s expert admitted that the second judge already rejected Mr. Argush's theory and accepted Loury's damages theory. The trial court barred Mr. Loury’s expert and dismissed Loury's counterclaim with prejudice before convening the collection trial, and the jury ruled in Martin Law Firm’s favor. Mr. Loury appealed the trial court's pretrial rulings barring his liability expert from testifying in support of his legal malpractice counterclaim, denying his motion for summary judgment on that counterclaim, and denying his motion to amend his counterclaim by adding attorney Joseph A. Martin as a codefendant. In affirming the trial court’s decision, the Appellate Division held that the trial court properly excluded Loury’s expert testimony in the counterclaim against Martin Law Firm because the expert could not explain how calling Loury as a rebuttal witness would have increased damages when the second judge already rejected Mr. Argush's testimony and accepted Loury's damages theory, making the expert’s causation opinion speculative. The Appellate Division also held that the trial court properly denied Mr. Loury's summary judgment motion on his malpractice counterclaim because reasonable minds could differ on whether Mr. Martin's alleged failures would have changed the second judge's damages award, given the judge already found Mr. Argush not credible, creating genuine factual disputes precluding summary judgment. Also, the Appellate Division held that the trial court properly denied Loury's May 2023 motion to add Joseph Martin individually because the statute of limitations expired in February 2022, six years after the 2016 appellate remand when Mr. Loury incurred new legal costs, and relation back did not apply because Mr. Loury knew Mr. Martin's identity throughout and strategically chose to sue only Martin Law Firm in his 2019 counterclaim.
