The plaintiff could not prove his Tennessee legal malpractice claim without expert proof that the defendant law firm breached the standard of care.
In Mamadou v. Gatti, Keltner, Bienvenu & Montesi, P.C., No. CT-3240-23 (Tenn. Ct. App. Dec. 22, 2025) (memorandum opinion), the plaintiff was represented by the defendant law firm in a workers’ compensation case. In a trial before an administrative judge, the plaintiff was awarded around $101,000. That amount was increased slightly by the Mississippi Workers’ Compensation Commission. The last sentence of the commission’s opinion stated that the “matter [was] remanded to the Administrative Judge for all further proceedings as may be necessary in this claim.” When the award was disbursed to the plaintiff, he signed a document stating that he was satisfied with the services he received from the defendant law firm. Later, the plaintiff filed a pro se complaint claiming that the defendant’s representation in the workers’ compensation claim fell below the applicable standard of care.
The defendant law firm submitted an affidavit from one of its attorneys stating that they complied with the standard of care. The defendant filed a motion for summary judgment on several bases, including that the plaintiff did not have the required expert proof to support his claim. The trial court agreed and granted the motion, and the Court of Appeals affirmed in a memorandum opinion.
