How Can You Challenge A Prior Conviction?

Before deciding on how to proceed, the attorney must request information regarding your prior conviction form the court. Requested documents may include minute orders, written waiver of constitutional rights, or the transcripts of the prior plea proceedings.

Additionally, the attorney may advise to request for bifurcation which would separate the prior from the recent DUI charge.

According to Vehicle Code § 41403- 41403(a), an attorney may file a motion to strike the prior conviction and must indicate in writing the specific alleged deprivation of the defendant’s constitutional rights. However, the defendant will have the burden of proof to prove by a preponderance of evidence supported by a factual and legal basis. Vehicle Code § 41403(b)(4).
