Each league usually has its own rules regarding these clauses; for example in the NBA, no-trade clauses can only be negotiated into contracts when a player has at least four years of service for the team he is signing the contract with and at least eight years total in the NBA.[2] Other leagues have other varying rules, for example in MLB the "Ten and Five" rule gives most players limited control on their tradability once they meet the ten and five criteria, which means the player has played in the league ten seasons and with the current team for at least five.
