Separating the mixture of the K-1(1270) and K-1(1400) states, the B -> K-1(1270, 1400)nu(nu) over bar transition form factors are calculated in the three-point QCD sum rule approach. The longitudinal, transverse and total decay widths as well as the asymmetry parameter, characterizing the polarization of the axial K-1(1270, 1400) and the branching ratio for these decays, are evaluated.
