A sample of {tau}{sup {+-}} {yields} K*{sup {+-}} decays with K*{sup {+-}} {yields} K{sub S}{sup 0}{pi}{sup {+-}} and K{sub S}{sup 0} {yields} {pi}{sup +}{pi}{sup -}, using 123.4 fb{sup -1} of data collected by the BaBar detector at the Stanford Linear Accelerator Center, is used to search for a direct CP violation effect in the charged Higgs sector. No evidence of CP violation is found and the imaginary part of the charged Higgs coupling, {l_brace}Im{r_brace}({Lambda}), in the Multi-Higgs-Doublet-Model is found to be at -0.284 < {l_brace}Im{r_brace}({Lambda}) < 0.200 at 90% Confidence Level. In addition the installation of the kk2f Monte Carlo generator into the BaBar software framework is described
