The form factors of the semileptonic Bc→S(AV) ℓν(ℓ=τ,μ,e) transitions, where S and AV denote the scalar Xc0 and axial vector (Xc1,hc) mesons, are calculated within the framework of the three-point QCD sum rules. The results of form factors are used to estimate the total decay widths and branching ratios of these transitions. A comparison of our results on branching ratios with the predictions of other approaches is also presented.
