We show that the decay mode $B\ensuremath{\rightarrow}D\ensuremath{\tau}{\ensuremath{\nu}}_{\ensuremath{\tau}}$ is competitive with and complementary to $B\ensuremath{\rightarrow}\ensuremath{\tau}{\ensuremath{\nu}}_{\ensuremath{\tau}}$ in the search for charged-Higgs effects. Updating the relevant form factors, we find that the differential distribution in the decay chain $\overline{B}\ensuremath{\rightarrow}D{\overline{\ensuremath{\nu}}}_{\ensuremath{\tau}}{\ensuremath{\tau}}^{\ensuremath{-}}[\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\nu}}_{\ensuremath{\tau}}]$ excellently discriminates between standard model and charged-Higgs contributions. By measuring the $D$ and ${\ensuremath{\pi}}^{\ensuremath{-}}$ …
