Provided is an apparatus and method for managing Digital Rights Management (DRM) contents in a portable terminal. The method includes when a license of the DRM content is consumed, changing license information, which is stored in an external memory, on the DRM content; storing information relating to changed data of the external memory into an internal memory; determining whether the changed license information stored in the external memory has changed by using the information stored in the internal memory when the DRM content is used; and determining whether the DRM content is available according to whether the changed license information has changed.
