Abstract. In this note we study reducing subspaces for weighted composition operators defined on $L^2(\Sigma )$. Some necessary and sufficient conditions are given for such operators to have two types of reducing subspaces of the forms $L^2(\Sigma_A)$ and $L^2(\mathcal{A})$. This is basically discussed by using conditional expectation properties.
