Pleading "no contest" to a criminal charge means you do not admit fault. Neither are you trying to fight for your innocence in a criminal trial.A plea of "no contest" implies only that the defendant has declined to present a defense, and would normally result in a conviction in the case. It means that you aren't contesting the charges against you. The results are usually the same as a guilty plea. A no contest plea is similar to a guilty plea. When you plead no contest, you technically admit that you are guilty of the crime being charged. What is the difference between a plea of not guilty, guilty, and no contest? A nocontest plea doesn't involve an admission of guilt. Instead, you're saying you won't contest the charges against you.
