  The results of the searches for CP non-conservation in the decays of tau
leptons are presented. No evidence of violation of CP symmetry is observed
neither in CLEO nor in BELLE data. Interpretation of these results is done
within the framework of a model with a scalar boson exchange. Limits on the
imaginary part of the coupling constant \Lambda, parameterizing the relative
contribution of diagrams that would lead to CP violation, are -0.046
<\Im(\Lambda) < 0.022 at 90% C.L. and |\Im(\Lambda)| < 1.7 at 90% C.L. in tau->
pi pi^0 nu_{\tau} and tau-> K pi^0 nu_{\tau} modes, respectively.
