Some sufficient conditions are found for the distribution of the Ornstein–Uhlenbeck process with Lévy noise to be absolutely continuous or to have a smooth density. These conditions are necessary for one-dimensional processes with a nondegenerate drift coefficient. We also give a multidimensional analog of the condition that the drift parameter is nondegenerate.
