Data collected by ALEPH in the years 1990, 1991 and 1992 have been used to update a previous search for CP violation in the decay of the Z into tau(+)tau(-). The measurement of the weak dipole form factor of the tau lepton has been performed by studying correlations between the tau leptons. No signal of CP violation was found. The weak dipole form factor is found to be over tilde d(tau) = (+0.15 +/- 0.58(stat) +/- 0.38(sys)) 10(-17)e x cm, obtained with 19628 identified tau(+)tau(-) events. This gives an upper limit on the weak dipole form factor of |over tilde d(tau)| < 1.5 . 10(-17)e x cm at the 95% confidence level
