We consider transformation of measure for diffusions with discontinuous drift analogous to the Girsanov transformation. For the drift it is possible to extract discontinuous component as a step function and derive the transformation of the measure of initial diffusion to the measure of diffusion with continuous drift. It is considered an application of the general result to the Ornstein–Uhlenbeck process with discontinuous drift.
