We study the nonresonant three-body decays of B+ → Ds (*)-K+π+ and Bd → Ds (*)-K0π+. We find that these decays can provide the information on the time-like form factors of Ds (*) K. We also explicitly investigate Bd → Ds (*)-K*+ decays by discriminating the nonresonant contributions with the unknown Ds (*) wave functions being fixed by the measured mode of Bd → Ds -K+.
