When facing criminal charges, a defense lawyer acts as your navigation and protector, especially if the crime is serious. Like how you would not walk in the forest without a tour guide, you would not walk in court proceedings without a defense attorney. Imagine the losses you would incur if convicted, for instance, tainted reputation, income loss, and loss of various privileges.
Arizona is among the states with the toughest criminal and DUI laws in the US. You don't want to risk it all by handling the case alone, so make an informed choice and talk to a criminal lawyer when you face arrest or learn about your charges. You want to hire a specialized DUI or criminal defense lawyer and not a jack-of-all-trades one to represent you.
DUI and criminal laws change radically after a short time of enactment. The lawyer you hire should have defended cases similar to yours before. A lawyer who has handled many cases knows the most current laws, is familiar with the jury, proceedings, and the strongest defense strategies. The attorney must be licensed to practice law in Arizona too.
Be cautious when hiring an attorney licensed in Arizona but resides in another state where they also practice. This is because an Arizona attorney has a closer relation with Arizona judges and prosecutors, adding to a higher reputation.
