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.It means that you aren't contesting the charges against you. The results are usually the same as a guilty plea. In the criminal sense, there is no difference. "No contest" is a "guilty" plea. A nocontest plea doesn't involve an admission of guilt. Instead, you're saying you won't contest the charges against you. 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.
