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.When you plead no contest to charges, you are essentially doing the same thing as admitting guilt in the case. In the criminal sense, there is no difference. "No contest" is a "guilty" plea. The difference is in the admission of guilt. It means that you aren't contesting the charges against you. The results are usually the same as 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.
