The Oklahoma Petition to Enter Plea of Guilty is a legal document used when a defendant wishes to enter a plea of guilty to a criminal charge in Oklahoma. This document is usually filed in the district court of the county in which the charge was filed. It must be signed by the defendant and the attorney for the defendant, and the prosecutor must also agree to the plea. The Oklahoma Petition to Enter Plea of Guilty must include the type of charge, the plea of guilty, the defendant's understanding of the plea, and the rights that are waived as a result of the plea. There are three types of Oklahoma Petition to Enter Plea of Guilty: a "straight plea," an "Alford plea," and a "no contest plea." A straight plea is when the defendant admits guilt. An Alford plea is when the defendant pleads guilty but does not admit guilt. A no contest plea is when the defendant does not admit or deny guilt, but agrees to accept a conviction.
