    • Seth successfully defended a Motion for Partial Summary Judgment brought by Plaintiff where Plaintiff tried to argue that the necessary cost of tearing out and replacing non-damaged property in order to access plumbing was outside of Defendant's $10,000 Limited Water Damage Coverage Endorsement and Plaintiff should be able to recover in excess of the $10,000 limit.  Defendant had tendered the policy limit prior to commencement of the lawsuit. The court ruled against Plaintiff and in favor of Defendant finding that the cost of tear out and replacement was within the policy's endorsement and Defendant's total claim for damages was limited to $10,000. This ruling enabled Defendant to later obtain Summary Judgment against Plaintiff for having tendered the limits prior to commencement of action. Thus, Plaintiff had no cause of action for breach of contract.  
    • Defendant tendered payment for the full amount of invoices with the 90 day statutory period. Unbeknownst to Defendant, Plaintiff prematurely filed a lawsuit prior to Defendant's payment. Plaintiff tried to argue Defendant confessed judgment and Plaintiff's counsel was entitled to attorney's fees. Seth filed a Motion for Sanctions and Motion for Summary Judgment. Plaintiff dismissed the case with prejudice prior to the hearings.

Third DCA Holds Presumption of Prejudice Applies to Any Post-Loss Obligation Defense When Insurer Establishes Insured’s Failure to Comply with Obligation

June 11, 2026

Universal Property & Casualty Ins. Co. v Alvarez, No.3D24-1853, Fla. 3d. DCA, May 13, 2026. At issue in this appeal was the trial court’s jury instruction regarding presumption of prejudice and post-loss obligation defenses. Alvarez filed a breach of contract action arising out of her insurance claim pertaining to alleged damage from Hurricane Eta. Universal raised several affirmative defenses, including Alvarez’s violation of her contractual post-loss obligations. At the start of trial, the court ruled that the legal presumption of prejudice was inapplicable to all of Universal’s post-loss obligation defenses except prompt notice. Universal opposed the ruling and continued to object at the charge conference. At trial, there was undisputed evidence that Alvarez failed to comply with multiple post-loss obligations, in addition to her failure to provide prompt notice, such as not providing requested documents and failing to preserve damaged property. Universal introduced a records request letter and testified that it never received the requested documents. Alvarez admitted she was aware of the records request, and that her uncle purchased materials and repaired the roof before Universal inspected it. Based on the court’s ruling at the start of trial, the jury was instructed that the presumption of prejudice only applied to Universal’s prompt notice defense and none of its other post-loss obligation defenses. The jury returned a verdict in favor of Alvarez, and the court subsequently denied Universal’s post-trial motions. Universal appealed the trial court’s entry of final judgment and denial of its post-trial motions for directed verdict or a new trial. On appeal, Universal contended the trial court erred in its jury instruction regarding the presumption of prejudice. In reversing the trial court, the Third DCA looked to its prior holding in American Integrity Ins. Co. v. Estrada, 276 So. 3d 905 (Fla. 3d DCA 2019). ‘In Estrada, we held that “when an insurer has alleged, as an affirmative defense to coverage, and thereafter has subsequently established, that an insured has failed to substantially comply with a contractually mandated post-loss obligation, prejudice to the insurer from the insured's material breach is presumed, and the burden then shifts to the insured to show that any breach of post-loss obligations did not prejudice the insurer.”’ Alvarez, at 4 (quoting Estrada, at 916). ‘In reversing the trial court, we instructed, “If American Integrity establishes that Estrada failed to materially satisfy any contractually mandated post-loss obligations, then the burden shifts to Estrada to establish that American Integrity was not prejudiced by Estrada's breach.”’ Id., at 4 (quoting Estrada, at 917) (emphasis added). The Third DCA found that the evidence at trial was sufficient enough to have required the trial court to instruct the jury on Universal’s presumption of prejudice to all of its post-loss obligation defenses. Since the court’s instruction to the jury was an inaccurate statement of law, the Third DCA ruled the trial court committed reversible error, and reversed and remanded for a new trial.

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.
