We calculate the new physics effects to the branching ratios of the lepton flavor conserving decays Z - l(+)l(-) in the framework of the general two Higgs doublet model. We predict the upper limits for the couplings \(xi) over bar (D)(N,mutau)\ and \(xi) over bar (D)(N,tautau)\ as 3 x 10(2) GeV and 1 x 10(2) GeV, respectively.
