Guilty means you're saying "yes, I did it. " No contest means you're saying, "I'm not saying I did or did not do it.In the criminal sense, there is no difference. "No contest" is a "guilty" plea. Pleading no contest is similar to a guilty plea in that you do not dispute the charges against you, and all the consequences are the same. If you plead "guilty" or "no contest," you will be found guilty and should be prepared to pay the fine. 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, in essence, has the same outcome of a guilty plea. You are going to have to pay the fine.
