Vacating or overturning a first DUI conviction in California is difficult but not impossible, and the path depends on the exact circumstances of your case. If your attorney failed to properly advise you on the immigration, licensing, or professional consequences of your plea, you may have grounds to file a motion under Penal Code section 1473.7 or 1018 to withdraw the plea if you can show prejudice. In some cases, ineffective assistance of counsel claims can also support post-conviction relief, but success requires strong evidence that your lawyer’s errors directly affected your decision to plead. Relief is not automatic and judges scrutinize these motions closely, so the best step is to consult with a post-conviction specialist who practices in the county where you were convicted, since each court and DA’s office handles these requests differently.
