In tournament Chess games, such a character can be reffered to as a 'referee', but is more commonly described as the adjudicator. It is the adjudicator's duty to call illegal moves as well as to monitor the abidance of rules by the players themselves.
In most chess tournaments, there are a handful of people known as Tournament Directors, or TD's. If an issue arises, then the players call over a TD, who takes care of the situation. In some tournaments, however, this is not the case. These tournaments often involve some of the best players in the world. In these tournaments, there is a person called the arbiter at every board. He has similar responsibilities to those of a TD, but he is responsible for only one game at a time. Additionally, a person must be approved by FIDE in order to be an arbiter, while anyone who knows the rules of chess and has attained TD certification can be a TD.
There are supervisors that walk around to address any problems that may arise.
