It refers to the defendants plea to the court of law that he/she would not fight against or dispute the allegations or charges filed against him/her. It means he/she will not contest the lawsuit. Court cannot take the stance of no-contest as accepting guilt. It is a different fact that the defendant does not want to dispute the charges and it will be on the plaintiff to prove the charges. But in its way, the no-contest plea needs a considerable convincing on the part of defendant to the court in order to get the plea in his/her favour.
