  The cross sections and polarization components of the $\tau$ leptons produced
in the charged current induced quasielastic $\nu_\tau~(\bar\nu_\tau) - N$
scattering have been studied. The theoretical uncertainties arising due to the
use of different vector form factors and the axial dipole mass in the axial
vector form factor have been investigated. Due to the high mass of $\tau$
lepton, the contributions from the term containing pseudoscalar and second
class current form factors are non-negligible and contribute to the uncertainty
in the cross section and polarization observables as these form factors are not
well known. In view of the currently proposed experiments by DUNE, SHiP and
DsTau collaborations to study the production of $\tau$ lepton, an updated
calculation of the cross sections and polarizations of tau leptons in the case
of quasielastic production have been done and the numerical results have been
presented along with a discussion of the theoretical uncertainties.
