Legally speaking, a no contest plea has the same effect as a guilty plea on a conviction when it comes to sentencing. A nocontest plea is a way of admitting guilt in a criminal case but avoiding having a conviction of guilt on your record.A no contest plea is more of a civil issue. If you were in an accident a guilty plea is an automatic admission of liability. The main difference between the two pleas is a defendant who pleads no contest is not admitting guilt. Contest plea allows you to avoid claiming guilt for the offense you've been charged with. Functionally, however, it's no different than a guilty plea. In the criminal sense, there is no difference. "No contest" is a "guilty" plea. A nocontest plea is similar to a guilty plea, except the victim cannot file a lawsuit against you in a civil court for damages later on.
