We present a search for the decay B{sup +}{yields}a{sub 1}{sup +}(1260)K{sup *0}(892). The data, collected with the BABAR detector at the SLAC National Accelerator Laboratory, represent 465x10{sup 6}BB pairs produced in e{sup +}e{sup -} annihilation at the energy of the {Upsilon}(4S). We find no significant signal and set an upper limit at 90% confidence level on the product of branching fractions B(B{sup +}{yields}a{sub 1}{sup +}(1260)K{sup *0}(892))xB(a{sub 1}{sup +}(1260){yields}{pi}{sup +}{pi}{sup -}{pi}{sup +}) of 1.8x10{sup -6}.
