Whenever two or more than two interlocutors are involved in a talk conversations tend to obey some rules by which every party can talk, as it is his/her right in that conversation. To avoid conversational disturbances and to yield an organized type of conversation, interlocutors may need the turn taking principles constantly. The general term referred to such principles is local management system (LMS). This, has in itself other components such as Turn Constructional Units (TCU), Transition Relevant Place (TRP), floor taking, and how all this, is done. Having Sacks, Schegloff and Jefferson’s (1974) framework and terminology in mind, this study yields an opportunity to investigate cases where and how LMS occurs. It also concentrates on un/successful turn taking instances. For the present study, ten minutes is selected from the Iranian live debate program. One of the merits of this data is that it happens naturally without any preplanning of the speech contents. The findings show turns and rules of LMS are violated for constant floor taking and longer floor occupying (floor holding).
