Possible deviations from the tau-mu-e universality are discussed in the framework of the standard model with four families and in that of the E6 model. It is shown that the experimental study of spin asymmetry in the process e+e- --> Z --> tau+tau- will give direct information on the real tau-nonuniversality due to the mixing of the usual and exotic fermions.
