The possible transverse polarization of the τ-lepton, which is T -odd and can be used to measure CP -violation, is estimated precisely in the radiative decay mode B c → τ τ γ with possible parameters for the multi Higgs doublet model and the R -parity violating supersymmetric model. We find that the up-bound of the transverse polarization with possible parameters in the models is at very different levels, i.e. it can be ≤15 ∼ 23% for the former but ≤0.1% for the latter, and it will be accessible experimentally soon.
