We evaluate the compositeness effects of leptons on the vertex Wτντ in the context of an effective Lagrangian approach and get the corrections to the non universal coupling gτ where we consider that only the third family is composed. We find the allowed region from the experimental gτ/ge quotient for (Λ versus m*) plane when the masses of the excited states of the third generation are considered equal, i.e., mτ*=mϑτ*=m*.
