Cease and desist letter 或 letter of demand 即是警告函。
一般上， 商标致持有人应该在没进行诉讼前先发出 警告函。 这是为了遵从 Civil Dispute Resolution Act 2011 司法纠纷了结法规 2011. 此法规勒令当事人应 真诚的 谋求和解。
在草写警告函时， 必需留意收信人有权起诉警告函 相当于莫须有的威胁。在1995年商标法里， 凭空威胁受害人有权起诉威胁者。所以必须确定商标已被注册而不只是在申请当中，并且确实侵权真相， 也确认对方商标是否足够像似。
如果警告函是由职业律师寄出，信函不得索求律师费用， 否则会处罚律师职业道德条规。
