Public Defender or Private Lawyer in Arizona? Key Differences

Public Defender or Private Lawyer in Arizona: What Is the Difference?

Both are licensed Arizona attorneys bound by the same ethical rules and the same duty of loyalty to the client. The differences are structural: who chooses the lawyer, who pays, how the caseload is set, and how much time and resources the case gets. Under A.R.S. § 11-584, a county public defender is appointed by the court to represent a person who is entitled to counsel and “not financially able to employ counsel” in Superior Court and justice court matters; city courts use contract or public defense attorneys the same way. A private attorney is chosen and paid by the client, sets their own caseload, and is retained at whatever stage the client decides, including before charges are filed.

What follows is an honest comparison, not a sales pitch. Arizona’s public defenders include some of the most experienced trial lawyers in the state, and many private defense attorneys, including on our team, trained there. The question is which model fits your case, your timeline, and your finances.

What a Public Defender Does Well

Public defenders are in the same courtrooms every day, know the judges and prosecutors, handle a high volume of cases, and try more cases than most private lawyers. Their offices have investigators, mitigation specialists, and appellate units. For a person who qualifies, appointment is fast, free, and provides competent counsel from the first appearance. A public defender is not a lesser lawyer; the constraint is time, not ability, and the appointment standard means many defendants who would prefer to choose their lawyer are not eligible.

What a Private Attorney Adds

• The pre-charge stage. A public defender cannot be appointed until there is a case. A private lawyer can act during the weeks between arrest and charging, when the MVD hearing deadline runs after a DUI, evidence can be preserved, and the charging prosecutor can be approached; see arrested for DUI but not charged.
• Time and continuity. One lawyer or one team from the first call through sentencing and sealing, with a caseload the firm controls.
• Experts on the client’s timeline. Toxicologists, forensic examiners, and investigators retained when the case needs them rather than when a budget approval clears.
• The collateral matters. The MVD hearing, professional licensing, immigration coordination, and the set-aside and sealing petitions afterward are outside a public defender’s appointment.
• Choice. The client picks a lawyer whose experience matches the charge, and can change lawyers if the relationship does not work.

How to Decide

• If you qualify and cannot afford private counsel, accept the appointment and work with your public defender; do not go unrepresented while deciding.
• If you can retain counsel and the case is pending charges, the pre-charge window is the strongest argument for doing it now.
• If the charge carries mandatory prison, registration, or a felony record, weigh the resources the case will need against the cost of retaining them.
• If you have already been appointed a public defender, you can retain private counsel at any point and the public defender withdraws; the transition is straightforward and requires only a substitution of counsel.

How Tamou Law Group Approaches the Comparison

Several of our attorneys came from public defender and prosecutor offices, and we tell prospective clients plainly when a public defender is the right choice for them. Where a client retains us, the difference we offer is timing and scope: the pre-charge window, the MVD hearing, experts retained when the case needs them, one team from the first call through sealing, and a caseload we control. What we will never offer is a guaranteed result, because no honest lawyer can. In every Maricopa County court.
