Va. Code § 19.2-296
Current with changes from the 2024 Legislative Session through ch. 778
A motion to withdraw a plea of guilty or nolo contendere may be made only before sentence is imposed or imposition of a sentence is suspended; but to correct manifest injustice, the court within twenty-one days after entry of a final order may set aside the judgment of conviction and permit the defendant to withdraw his plea.
