This paper is devoted to the proof of certain results on conditional diffusions. By using the Malliavin calculus of variations, it is shown that, under minimal conditions on the vectors fields which define a two component diffusion (x t, z t) and their Lie brackets, as, for any T⩾ 0, the conditional law of x t (t> 0), given B (z s, s⩽ T) a C∞ density.
