The standard model is extended with the \(S_3\) symmetry in which non zero \(\theta _{13}\) is obtained in the type I\(+\)II seesaw framework of neutrino mixing consistent with the current observation. Non zero contribution of CP asymmetry is discussed from the decay of scalar triplet in \(S_3\) extended standard model. Presence of right-handed neutrinos could explain both neutrino oscillation and non zero lepton asymmetry from the vertex correction of triplet decay, without including any other heavy triplet.
