He was married to Michele - who he encountered during his military service in St. Raphael, see below - in 1962 and was father of two sons, Jean-Michel and Patrice born respectively in 1963 and 1967 and both traders His stepdaughter was Pascale Mourrut, who was a candidate for the regional elections 2010 in Languedoc-Roussillon and municipal elections of 2014 Grau-du-Roi and his parliamentary assistant until 2012.

He then became employed at Salins du Midi, where he gained charge of maintenance and created the FO Union.

Especially after seeing the delayed development of Grau-du-Roi compared to the Var commons, Étienne Mourrot decided to engage in politics.

In 1965, at 25 years of age, he became alderman of the town run by the team of the Socialist Jean Bastide; although at bottom of the list, he was one of the best elected.

He then ran the local paper Lou Fanal for six years and, to oppose the management of the mayor, attended all council meetings and works records.

He went to local elections in 1979 in the canton of Aigues-Mortes, facing the councillors André Fabre and Jean Bastide, but lost.

After the 1984 to 1986 port developments, construction of municipal subdivisions Lou Lantern (1985), The Magnolias (1988) and Thessaloniki (1990), and the creation of the Maison des Vins at Espiguette took place.

On 15 August 1984, he decided to start management of municipalization in Grau-du-Roi arenas, and he entrusted Philippe Cuillé to do such.

While being candidate of the RPR for senatorial elections in September 1998, he was defeated in the second round, coming in fifth place behind Gilbert Baumet.
