If you have a prior criminal history or other DUIs that could increase costs. If you're on probation, or parole, or have other charges that have to be addressed at the same time, then your legal costs will go up.   Collisions can increase time and money because there will be a collision report, and questions about who is at fault.   Injuries can turn a misdemeanor DUI into a felony DUI. A felony case is obviously more work.    Some factors we won't know until you meet with and hire us. For example, the best defense can be problems in the administration and analysis of a blood test or a breath test. This requires independent testing and witnesses, which is, of course, more expensive.  Often, these issues do not present themselves until we obtain the reports from law enforcement and evaluate the lab work done.   Motions are typically related to whether the arrest and collection of blood or breath are in violation of the California or federal constitution. These motions typically take half a day with witnesses that need to be cross-examined. There are briefs that need to be submitted beforehand. Where motions are concerned, it doesn't matter whether it's a first offense or not in this case, because it's about law enforcement's conduct.    If we're not able to reach a resolution that satisfies you then we'll quote your trial fee based on our understanding of the case. This fee would be required before we set the trial date.
