The ratification by the Generalitat came at the proposal of the Nules City Council, which in the Plenary Session of October 31, 2025, unanimously adopted the descriptive text of the municipal symbol. This decision was made in accordance with the modifications suggested by the Consell Tècnic d’Heràldica i Vexil·lologia (Technical Council of Heraldry and Vexillology).
The Consell Tècnic d’Heràldica i Vexil·lologia, in its session on November 28, 2025, had already issued a favorable report on the project for Nules' municipal coat of arms, paving the way for its final approval.
The coat of arms for the municipality of Nules is described as follows: a quadrilong shield with a rounded point. On a white field, a lion sinister of its color, flanked by the letters S and L in sable. At the chief, lozengy of gold and gules. An orle surrounds the shield with the legend: «LA FIDELÍSIMA Y MUY LEAL VILLA Y HONOR DE NULES», in sable. At the crest, an open royal crown, traditional in the Kingdom of Valencia.
