Abstract. Let be a trivial Morita context. This article concerns the quasipolar properties of trivial Morita contexts over local rings. Necessary and sufficient conditions for a single matrix of (a trivial Morita context over local rings) to be quasipolar are obtained. And then we get a sufficient condition for to be a quasipolar ring.
