We calculate the vector and axial-vector form factors of B{sub u,d,s} decays into P-wave axial-vector mesons in the light-cone sum rule approach. For the sum rule results, we have included corrections of order m{sub A}/m{sub b}, where m{sub A} is the mass of the axial-vector meson A. The results are relevant to the light-cone distribution amplitudes of the axial-vector mesons. It is important to note that, owing to the G parity, the chiral-even two-parton light-cone distribution amplitudes of the {sup 3}P{sub 1} ({sup 1}P{sub 1}) mesons are symmetric (antisymmetric) under the exchange of quark and antiquark momentum fractions in the SU(3) limit. For chiral-odd light-cone distribution amplitudes, it is the other way around. The predictions for decay rates of B{sub u,d,s}{yields}Ae{nu}{sub e} are also presented.
