The rare B-c -> D(s,d)(*)l(+)l(-) decays are investigated in the framework of the three-point QCD sum rules approach. Considering the gluon condensate corrections to the correlation function, the form factors relevant to these transitions are calculated. The total decay width and branching ratio for these decays are also evaluated. The results for the branching ratios are in good agreement with the quark models.
