We report a study of the decays B{yields}D{sub s1}(2536){sup +}D{sup (*)}, where D{sup (*)} is D{sup 0}, D{sup -} or D*{sup -}, using a sample of 657x10{sup 6}BB pairs collected at the {Upsilon}(4S) resonance with the Belle detector at the KEKB asymmetric-energy e{sup +}e{sup -} collider. The branching fractions of the decays B{sup +}{yields}D{sub s1}(2536){sup +}D{sup 0}, B{sup 0}{yields}D{sub s1}(2536){sup +}D{sup -} and B{sup 0}{yields}D{sub s1}(2536){sup +}D{sup *-} multiplied by that of D{sub s1}(2536){sup +}{yields}(D*{sup 0}K{sup +}+D*{sup +}K{sup 0}) are found to be (3.97{+-}0.85{+-}0.56)x10{sup -4}, (2.75{+-}0.62{+-}0.36)x10{sup -4} and (5.01{+-}1.21{+-}0.70)x10{sup -4}, respectively. The ratio B(D{sub s1}{yields}D*{sup 0}K{sup +})/B(D{sub s1}{yields}D*{sup +}K{sup 0}) is measured to be 0.88{+-}0.24{+-}0.08.
