We analyze the rare semileptonic B-c -> D-s0*l(+)l(-), (l = e, mu, tau) and B-c -> D-s0*nu(nu) over bar decays in the framework of the three-point QCD sum rules. D-s0* is a scalar meson with total spin 0 and even parity. Taking into account the gluon condensate contributions as the important correction of the nonperturbative parts of the correlation function and the large effects of Coulombic corrections, the relevant form factors of these transitions have been calculated. The branching fractions and longitudinal lepton polarization asymmetry are also investigated.
