Marshall Dennehey is uniquely positioned to defend lawyers’ professional liability (LPL) claims, and we have been doing so for over three decades. In addition to defending civil matters, we also represent attorneys in disciplinary matters, and we furnish counseling and risk management advice to law firms.
Our familiarity with the bench and bar fosters our ability to manage sensitive issues inherent in many legal malpractice and bar complaint matters. Representing our colleagues at the bar requires tact, finesse, experience and poise, and our attorneys are especially sensitive to reputational issues.
The prototypical legal malpractice case involves two matters: the act or omission of the attorney and the underlying lawsuit or transaction. With approximately 50 distinct practice groups, Marshall Dennehey’s LPL clients benefit from our firmwide civil defense litigation practice. For example, when a legal malpractice claim derives from an underlying medical malpractice matter, members of our Health Care Liability Practice Group bring depth and added knowledge to the defense of the matter.
In addition to the firm’s prowess in defending attorneys and their firms, Marshall Dennehey is proud of its success in providing creative solutions to traditional legal issues. The attorneys within the practice group look for “business solutions” and have structured the resolution of cases by resurrecting the underlying transaction which gave rise to the legal malpractice claim.
The attorneys within this practice are involved in precedent-setting matters. Also, we are thought leaders in the professional liability industry as frequent authors and speakers on risk management and legal malpractice defense.
In addition to defending these claims in the seven states where our offices are located, we try cases as lead counsel on a national basis and associate with local counsel when necessary. The firm has provided counsel to respected lawyers from essentially every domestic insurance carrier and has represented lawyers through the London market.

Successful Defense of High‑Profile Condo Board Election Challenge as Court Dismisses Claims With Prejudice
One Month – 4 Outstanding Results! Aaron Moore Obtained Four Successful Results on Behalf of Clients in the Span of One Month
Defense verdict on behalf of a real estate broker and agent. The plaintiffs, homebuyers, claimed that the sellers’ broker and agent were liable to them for the value of fixtures that were taken by the sellers when they vacated the property, which were alleged to have been included in the sale. At a bench trial, the judge determined that neither the broker nor the agent could be held liable to the plaintiffs because the representations regarding what was included in the sale were made by the sellers. Supreme Court affirmance of dismissal of a complex legal malpractice lawsuit. Aaron and Carol Vanderwoude obtained a Delaware Supreme Court affirmance of the trial court’s dismissal of a complex legal malpractice claim. The plaintiffs, seven affiliated companies and their owners in the business of developing property, had been sued by their bank for defaulting on multiple lines of credit. The bank filed multiple lawsuits against the property developers, claiming approximately $7 million in damages, plus attorneys’ fees, which were recoverable pursuant to the terms of the promissory notes. The property developers retained our client to defend the lawsuits, asserting that the amounts claimed to be owed to the bank were significantly overstated. Our client vigorously defended the bank’s underlying lawsuits. Ultimately, the property developers settled the bank’s lawsuits for the entire amount owed, plus interest and the bank’s legal fees. The developers argued that its attorneys should have advised them to settle the bank’s claims after the lawsuits were commenced and that, if they had done so, they would not have had to pay the bank’s legal fees, our client’s legal fees, or expert witness fees, or the additional interest on the loan. The property developers also claimed that not settling with the bank earlier caused them lost business opportunities valued at nearly $1 million. The plaintiffs’ legal malpractice claims were dismissed because their expert witness, a Maryland attorney with no business litigation experience, was not qualified to serve as an expert and because their damages claims were speculative. Motion to dismiss in complex matter involving claims of fraud, misappropriation of trade secrets, tortious interference with contractual relations, and piercing the corporate veil. The plaintiff, an investment fund, had purchased a business that was controlled and primarily owned by our client. The business ultimately went bankrupt, and the plaintiff claimed that the purchase was premised upon misrepresentation by our client. The plaintiff maintained that jurisdiction in Delaware was proper pursuant to the Asset Purchase Agreement. The District Court was persuaded by arguments reflecting that it lacked personal jurisdiction over our client, a citizen of Canada, even though he signed the Asset Purchase Agreement which included language conferring jurisdiction over claims arising from the sale in Delaware. The court agreed that our client did not sign the agreement in his individual capacity, and the plaintiff’s piercing the corporate veil allegations were insufficient to confer personal jurisdiction. Dismissal of an unjust enrichment claim. Obtained dismissal of an unjust enrichment claim brought by a condominium unit owner against the attorneys who represented her condominium association. The unit owner claimed that the law firm was liable to her for unjust enrichment in connection with legal fees it received from the association for legal services provided in efforts to collect on past due assessments owed by the unit owner. Pursuant to the association’s governing documents, the charges were passed on to the unit owner. The court agreed that the fees that were paid to our client by the condominium association were properly earned.

Appellate Division Affirms Dismissal of Legal Malpractice Counterclaim Against Martin Law Firm
July 29, 2026
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.

Delaware Superior Court Clarifies Pleading Standard for Legal Malpractice Claims
July 29, 2026
In the matter of Edelstein v. Kirschner, No. N25C-09-018 FJJ, 2026 Del. Super. LEXIS 45, at *1 (Super. Ct. Jan. 29, 2026), the plaintiff law firm sued its former client for unpaid legal fees in the amount of $4,399.35. The former client asserted a counterclaim alleging legal malpractice. More, specifically, the former client claimed that his lawyer committed malpractice be recommending that he settle an underlying lawsuit by entering into a stipulated judgment for an excessive amount with interest that was accruing at “an outlandish” interest rate. The law firm moved to dismiss the counterclaim on the basis that its former client had not alleged facts reflecting that he could prove the case within the case. That is, facts reflecting that his attorneys caused him to lose the underlying case. The Superior Court held that while a legal malpractice plaintiff in cases arising from underlying litigation must prove the case within the case to survive a summary judgment motion, he does not need to plead facts reflecting as much in order to survive a motion to dismiss. While this case addresses the pleading requirements of a legal malpractice case in Delaware, it also serves as reminder that chasing unpaid legal fees from a former client can often give rise to a legal malpractice counterclaim. Attorneys seeking to collect unpaid legal fees should ensure that the fees they seek are for a significant amount, which would be recoverable if a judgment is obtained. Otherwise, the effort could backfire.
