  Motivated by the rapid development of heavy flavor physics experiment, we
study the tree-dominated nonleptonic $\bar{B}_{u,d,s}^* \to
D_{u,d,s}^*V$~($V=D^{*-},D_s^{*-},K^{*-},{\rho}^-$) decays within the
factorization approach. The relevant transition form factors are calculated by
employing the covariant light-front quark model. The helicity amplitudes are
calculated and analyzed in detail, and a very clear hierarchy structure $
|H_{-0}| \approx 2|H_{00}| > |H_{0-}|\approx|H_{--}|>|H_{0+}|\approx|H_{++}|$
is presented. The branching fractions are computed and discussed. Numerically,
the CKM-favored $\bar{B}^*_q\to D^*_q \rho^{-}$ and $D^*_q D_s^{*-}$ decays
have relatively large branching fractions, $\gtrsim {\cal O}(10^{-8})$, and are
hopeful to be observed by LHC and Belle-II experiments in the future.
