PURPOSE: A control method of simultaneity in a co-work is provided to reduce an overhead of a server, caused by controlling a simultaneity, by performing only role detecting a crash by use of a time stamp in a server of an operation generated in the co-work. The method is provided to maintain a consistency of the co-work by automatically deleting the crash, through returning or converting, by use of a locking and ordering just in a client generated the crash. CONSTITUTION: A control method of simultaneity in a co-work comprises the steps of: comparing simultaneity between a global time stamp and a time stamp accepted an object operation, after accepting the object operation from a client in a server; increasing the time stamp, after performing the operation through a message allowable a locking and a message allowable a partial locking, if the compared time stamps are consisted; deciding whether a media object identifier is the same, if not; transmitting the message allowable the partial locking, if the identifier is decided not to be the same; and transmitting a message refusing a locking, if the identifier is decided to.
