I think you mean remainderman. It indicates a future fee interest after another interest has expired. In some states a life estate is created by devising or granting a life estate to one person with the fee to go to another person after the death of the life estate holder. For example: A owns property and provides in his will that the property will go to B for life and after B's death the property will go to C to be hers absolutely. C would be called the "remainderman" . . . or "remainderperson".
