In anticipation of abundant $B^*$ data samples at high-luminosityheavy-flavor experiments in the future, the tree-dominated semileptonic$\bar{B}^*_{u,d,s} \to P \ell^- \bar{\nu}_\ell$ $(P=D\,,D_s\,,\pi\,,K)$ decaysare studied within the Standard Model. After a detailed calculation of thehelicity amplitudes, the theoretical predictions for branching fraction~(decayrate), lepton spin asymmetry, forward-backward asymmetry and ratio$R_D^{\ast(L)}$ are firstly presented. It is found that the CKM-favored$\bar{B}^* \to D \ell^- \bar{\nu}_\ell$ decays have relatively large branchingfractions of ${\cal O}(10^{-9})$$\sim$${\cal O}(10^{-7})$, and are in the scopeof running LHC and forthcoming SuperKEKB/Belle-II experiments.
