In this work we analyze a non-minimal Lorentz-violating extension of the electroweak theory in the fermionic sector. Firstly we analyze the relation between the CKM rotation in the quark sector and possible contributions of this new coupling to flavor changing neutral currents processes. In sequel we look for non-diagonal terms through possible lepton flavor violation decays. Strong bounds are presented to the Lorentz violating parameters of both the quark and the lepton sectors.
