We perform a complete simulation of the process e+e−→τ+τ−ννˉ, where ν can be an electron, muon or tau neutrino, in the context of a general Higgs coupling to τ leptons. We analyse various kinematical distributions and obtain the sensitivity regions in the parameter space that can be explored at a future e+e− collider. In particular, inclusion of W boson fusion enhances the sensitivity significantly.
