    • Successfully obtained dismissal of claims brought derivatively and directly by a corporation, including aiding and abetting breach of fiduciary duty and tortious interference with contract. The claims were brought against our client, an out of state attorney who previously represented the corporation and its former director. The Court granted the attorney’s Motion to Dismiss, concluding that the plaintiffs failed to sufficiently allege facts that would confer personal jurisdiction over the attorney under a conspiracy theory.
    • Successfully obtained dismissal of wrongful use of civil proceedings claims brought against our clients, two attorneys who were alleged to have wrongfully prosecuted a professional negligence claim against the plaintiff, a real estate agent. The plaintiff would not accept any settlement that was less than policy limits.

The plaintiff would not accept any settlement that was less than policy limits. After five years of litigation, the Court granted the attorney defendants’ summary judgment motion, concluding that the plaintiff failed to adduce facts that would reflect that the attorneys prosecuted the underlying action in a grossly negligent manner, or without probable cause. The Court also held that the plaintiff was unable to demonstrate that the underlying lawsuit was prosecuted for an improper purpose.
    • Successfully defended a home inspector before the Delaware Division of Professional Regulation. The Claimants sought disciplinary action against our client in connection with his inspection of their home. We were able to persuade the Division that the complained of defects at the property were not subject to inspection because they were not visible at the time of inspection. The Division weighed all concerns involved in the matter and on November 1, 2023, it concluded that the facts did not reflect a violation of the laws, rules, and regulations that governed the activities of the licensed professional.
    • A unanimous jury found in favor of our clients, a lawyer and his law firm in a legal malpractice case arising out of the lawyer’s drafting of a postnuptial agreement. The postnuptial agreement was invalidated by a family court judge, causing the husband to lose approximately $1.2 million as part of a subsequent property separation agreement. The jury considered testimony from the plaintiff’s ex-wife which reflected that she had signed the agreement under duress and concluded that the plaintiff could not demonstrate that the postnuptial agreement was invalidated as a result of anything the lawyer did.

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.

Unanimous Appellate Decision Preserves Defense Win in Legal Malpractice Suit

We successfully defended an appeal from a jury verdict previously secured by members of our Lawyers’ Professional Liability Department in favor of the firm’s client in a legal malpractice case. The plaintiffs initially asserted multiple tort claims and a claim under the Unfair Trade Practices and Consumer Protection Law, which were dismissed by the trial court upon partial grant of the defense’s motion for judgment on the pleadings. The case proceeded to trial on a remaining breach of contract claim, resulting in a defense verdict. On appeal, the plaintiffs challenged the trial court’s rulings on both the motion for judgment on the pleadings and a motion in limine related to evidentiary exclusions. The Pennsylvania Superior Court unanimously affirmed the trial court’s rulings, holding that the tort claims were time-barred and that the plaintiffs had waived their evidentiary argument by failing to properly develop it in their appellate brief.

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.

Delaware Superior Court Addresses Continuous Representation Doctrine in Legal Malpractice Case—But Was It Really Applied?

January 1, 2026

In what the court stated was a matter of first impression, the Delaware Superior Court applied the “continuous representation doctrine” in a legal malpractice case. In this case, the plaintiff claimed that his attorneys did not take any meaningful action to prosecute his underlying lawsuit and failed to sufficiently communicate with him. The court dismissed the underlying action sua sponte for failure to prosecute. The plaintiff maintained he first learned that his underlying claims had been dismissed by the Superior Court 18 months after the dismissal. He then commenced his legal malpractice action more than three years after the dismissal. The defendant attorneys moved to dismiss the malpractice claims based on Delaware’s three-year statute of limitations, which, under the occurrence rule, began to accrue at the time of dismissal of the underlying action. The court held that the continuous representation doctrine was applicable because the “cause of action conceivably accrued at some point after the court dismissed the underlying suit” because the attorneys failed to take efforts to reopen the judgment. It appears that the Delaware Superior Court has conflated the “continuous representation doctrine” with the concept of continued negligence. There are some jurisdictions that recognize the continuous representation doctrine, which provides that a legal malpractice cause of action accrues at the end of the underlying representation, irrespective of when the negligence occurred during the representation. Delaware, however, follows the “occurrence rule,” which, in the absence of equitable tolling, provides that a cause of action accrues at the time of the alleged negligence. Here the court properly concluded that the cause of action could be deemed to have accrued after the dismissal of the underlying claims if the plaintiff could demonstrate continued negligence after the dismissal. The court’s use of the phrase “continuous representation doctrine,” however, could lead to confusion as to whether that doctrine is actually applicable in Delaware. The court entertained a motion for re-argument and issued a second opinion, where it made clear that the plaintiff’s claims were not time barred because of allegations of continued negligence. The second opinion did not reference the “continuous representation doctrine”; however, it did not specifically clarify that the doctrine was not applicable.

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.
