Legally speaking, a no contest plea has the same effect as a guilty plea on a conviction when it comes to sentencing. Pleading "no contest" means that you are not admitting guilt but are not contesting the charges either.The advantage of doing one in CA anyway is that a no contest plea cannot be used against you in civil proceedings whereas a guilty plea can. 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. A not guilty plea and a resulting PBJ are not the same as a nolo contendere or no contest plea. 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 and guilty plea are similar but some differences could affect your case. Find out what you need to know here.
