The structure of the D-1(0)(2420[2430]), (J(P) = 1(+)) mesons via analyzing the semileptonic B-c -> D(1)(0)l nu transition is considered in the framework of the three-point QCD sum rules. In this work, we consider the D-1(0)(2420[2430]) axial vectors as conventional c (u) over bar mesons. Taking into account the gluon condensate contributions, the relevant form factors are obtained. The obtained results for the form factors are used to evaluate the decay rate and the branching ratio.
