The temporal component of the heavy-light axial vector current is constructed to one-loop order in perturbation theory and to order 1/M, where M is the heavy quark mass, in terms of operators suitable for use in lattice simulations of B and D mesons. The O(a)-improved clover action is used for the massless light quark, where a is the lattice spacing, and propagation of the heavy quark is described by a nonrelativistic lattice action. {copyright} {ital 1998} {ital The American Physical Society}
