In order for a motion to be valid the following must take place:
- The meeting must be valid, which means the proper amount of notice should have been given to the board members, or committee members if we are talking about a committee.
- The meeting must have a quorum, which means there must be at least one more person than 50% of the board, or whatever rules you have about quorum.
- There must be a mover and a seconder. Without a seconder the motion dies.
- The motion must be passed by a majority of the members in attendance.
- The motion must be recorded in the minutes and the minutes must be approved.
If any of these things fail to occur, then you do not have a valid motion.
