Vicente Fernández's widow went to court to stop Televisa using his name for a biopic, and the series aired anyway

Vicente Fernández died after months in hospital and was buried on his 500-hectare ranch, Los Tres Potrillos, named for his sons Vicente Jr., Gerardo and Alejandro. Televisa produced an unauthorized biographical series, "El Último Rey," with Pablo Montero as Fernández. His widow, María del Refugio "Doña Cuquita" Abarca, and the family sued, alleging trademark violations and misuse of his name. A federal civil judge issued a suspension, and the Mexican Institute of Industrial Property (IMPI) imposed precautionary measures against Televisa. Televisa said it had received no court order barring broadcast and premiered the series on 14 March 2022. Televisa won its own provisional suspension. The family's lawyers, Del Toro Cazo, filed three amparos in Mexico City district courts, numbered 450/2022, 502/2022 and 461/2022. Later reporting said judges rejected the claim that the name "Vicente Fernández" was a registered trademark that blocked the series. In August 2022 the family was still litigating, including before IMPI. On the inheritance, Doña Cuquita said in August 2023 that there was no fight among the heirs. No final ruling in the Televisa case was found as of 2026.
