A DUI lawyer in Arizona typically costs between $2,500 and $25,000+ depending on the charge and complexity. Standard first-offense DUI under A.R.S. 28-1381 runs $2,500-$5,000 flat fee. Extreme DUI under A.R.S. 28-1382 runs $5,000-$10,000. Aggravated (felony) DUI under A.R.S. 28-1383 runs $10,000-$25,000+ due to jury trial and prison exposure.

The Cost Ranges by DUI Type
DUI legal fees in Arizona vary widely based on the specific charge, prior record, and complexity. Typical 2026 fee ranges from reputable Arizona defense firms:
| Charge Type | Fee Range (Flat) | Fee Range (Trial-Ready) |
|---|---|---|
| Standard first DUI (.08-.149) | $2,500 – $5,000 | $5,000 – $8,000 |
| Extreme DUI (.15-.199) | $5,000 – $8,000 | $8,000 – $12,000 |
| Super Extreme DUI (.20+) | $6,000 – $10,000 | $10,000 – $15,000 |
| Second DUI (misdemeanor) | $5,000 – $8,000 | $8,000 – $12,000 |
| Aggravated DUI (felony, 3rd offense or with child) | $10,000 – $18,000 | $18,000 – $25,000+ |
| DUI with accident/injury | $8,000 – $15,000 | $15,000 – $30,000+ |
| Multiple counts (DUI + reckless + etc.) | $5,000 – $12,000 | $12,000 – $20,000+ |
These ranges reflect Arizona market rates for experienced DUI defense attorneys. Lower-priced attorneys ($1,000-$2,500 for a first DUI) typically indicate either inexperience, high case volume with limited individual attention, or plea-focused practice that does not litigate. Higher-priced attorneys ($8,000+ for standard first DUI) usually indicate boutique DUI-only practices with extensive expert witness relationships.
What Determines the Actual Fee
Several factors move a fee quote up or down within the range:
- Charge severity. Higher BAC = higher fee due to mandatory jail exposure and reduced defense options.
- Prior record. Second or subsequent DUI within 84 months carries harsher penalties and typically higher fees due to increased litigation.
- BAC test evidence. Contested BAC evidence (calibration issues, blood test challenges) requires expert witnesses. Adds $1,500-$3,500 to expert costs.
- Traffic stop legality. Cases with Fourth Amendment issues under Fourth Amendment require suppression motions, which take substantial attorney time.
- Trial vs plea. A plea-negotiated resolution costs less than a trial. Trial-ready fees are typically 40-80% higher than flat plea fees.
- Court location. Rural Arizona counties (Yuma, La Paz, Cochise) sometimes cost less than Maricopa or Pima due to lower cost of living.
- Attorney experience. Former prosecutors, former judges, and DUI-only specialists command higher rates but often deliver better outcomes.
Under ABA Model Rule 1.5 (attorney fees), attorney fees must be reasonable and communicated in writing. Any attorney quoting a fee without explaining what it covers is providing incomplete information — get the scope in writing.
Flat Fee vs Hourly vs Retainer
Arizona DUI attorneys use three primary billing structures:
Flat fee (most common for DUI): A single price for defined scope. Common flat-fee scopes:
- “Pre-trial resolution” — attorney handles all pre-trial work, but not trial. If trial is needed, additional fee applies.
- “Through disposition” — flat fee covers plea negotiation and standard sentencing. Trial excluded.
- “All-inclusive” — flat fee covers everything through trial including any post-conviction motions. Rare, and higher-priced.
Hourly: Less common in DUI cases. Rates typically $250-$500/hour for Arizona DUI defense. Complex cases with unpredictable scope may use this structure. Retainer amounts commonly $3,000-$8,000 to start.
Retainer + hourly: Hybrid. A retainer is placed in trust and billed against as work is done. Attorney provides periodic invoices showing hours and remaining balance.
Recommended structure for most DUI defendants: flat fee “through disposition” with clearly written scope. Understand what is EXCLUDED. Common exclusions:
- Trial (usually additional $3,000-$8,000)
- Expert witnesses ($750-$2,500 per expert, defendant pays directly)
- MVD administrative hearing (some firms include, others charge $500-$1,500 separately)
- Motion to suppress (some firms include, others don’t)
- Appeal (always separate)
Additional Costs Beyond Attorney Fees
Attorney fees are only one line item in the total DUI cost. Full cost ranges for a first-offense standard DUI conviction in Arizona:
- Attorney fees: $2,500-$5,000
- Base fine: $1,250 (statutory minimum under A.R.S. 28-1381)
- Surcharges on fine: $1,050 (84% surcharge)
- Court costs and assessments: $500-$800
- Alcohol screening + counseling: $500-$1,200
- Ignition interlock device: $2-$4/day + $75-$150 installation. 12 months = ~$1,000-$1,500 total under Arizona MVD ignition interlock program
- MVD reinstatement fees: $200-$400
- SR-22 insurance: +$800-$2,000/year for 3 years above standard rates
- Probation supervision fees: $65-$100/month
- Community service: Time (typically 30 hours), not money
Total first-time DUI cost: $8,000-$15,000 all in, of which $2,500-$5,000 is attorney fees.
Extreme DUI adds $500-$1,500 in additional fine, extended interlock (18 months vs 12), and higher probation fees. Total: $12,000-$20,000.
Aggravated (felony) DUI adds prison costs (loss of income during incarceration), professional license consequences, and immigration issues (if non-citizen). Total: $20,000-$50,000+ in direct costs, plus career impact.
Payment Plans and Financing Options
Most Arizona DUI defense firms offer some form of payment structure:
- Split payment. Fee split into 2-3 installments over 30-60 days. Most common. Attorney typically requires 50-60% upfront, remainder due before trial or before final court appearance.
- Extended payment plans. Some firms allow 3-6 month payment terms with additional administrative fee.
- Third-party financing. LegalFee Financing, Trucanto, and similar services provide loans specifically for legal fees. Interest rates typically 12-24%.
- Credit card. Nearly universal option. Cash-back cards effectively reduce cost by 1-2%.
- Home equity / personal loans. For higher-fee felony cases, defendants sometimes tap home equity or personal loans. Interest rates typically 6-12%.
Under ABA Model Rule 1.5 (attorney fees), the specific fee arrangement must be documented in a written engagement letter. Any oral fee agreement or “we’ll figure it out later” is a warning sign.
Deposit safety: Legitimate flat fees are typically NOT deposited in the attorney’s trust account — flat fees are earned upon receipt under Arizona ethics rules. Hourly retainers ARE placed in trust. If an attorney says “flat fee” but also asks you to sign a trust deposit agreement, ask for clarification. The Consumer Financial Protection Bureau publishes consumer resources on attorney fee arrangements.
Why the Cheapest Lawyer Often Costs More
The cheapest DUI lawyer quote is usually not the cheapest total outcome. Here’s why:
- Plea-mill practice. A $1,500 DUI attorney typically handles 200+ cases per year. Time per case = 4-8 hours total. That’s enough to negotiate a standard plea, not enough to run a competent defense.
- No suppression motions. Fourth Amendment challenges are legally complex. Low-fee attorneys often skip them entirely because they take 10-20 hours per case. But suppressing bad evidence is often the highest-value action.
- No expert witnesses. Toxicology, calibration, and reconstruction experts cost $1,500-$3,500 each. Low-fee attorneys rarely retain them. But BAC accuracy challenges frequently require expert testimony.
- Higher plea outcomes. Studies of Arizona DUI outcomes consistently show reduced-charge and dismissed cases correlate with higher attorney fees. A plea to Extreme DUI vs a plea to standard DUI = 20 extra days of mandatory jail. That’s a $10,000+ real cost differential (lost wages, opportunity cost).
- Interlock and license consequences. Standard DUI = 12-month interlock. Extreme = 18 months. Reduced charge = potentially 6 months or none. The interlock cost delta alone can exceed $1,000.
The math: paying $5,000 for an experienced DUI attorney who negotiates the charge down from Extreme to Standard saves 20 days of jail (worth $8,000-$15,000 in lost income) plus 6 months of interlock ($300-$500) plus reduced insurance impact ($1,500+ over 3 years). That’s $10,000-$17,000 in real savings for a $3,500 fee differential.

Frequently Asked Questions
A standard first-offense DUI in Arizona typically costs $2,500 to $5,000 for a flat-fee plea resolution, or $5,000 to $8,000 for trial-ready representation. Extreme DUI (.15+) runs $5,000-$10,000. Super Extreme DUI (.20+) runs $6,000-$10,000. Aggravated (felony) DUI ranges $10,000-$25,000+ due to jury trial and prison exposure. Prices vary by attorney experience, county, and case complexity.
Flat fee is standard and typically preferable for DUI cases because the scope is relatively predictable. Look for a flat fee ‘through disposition’ with clear written scope. Understand what’s excluded (typically trial, expert witnesses, MVD hearing, suppression motions). Hourly billing is unusual in DUI defense and typically indicates the attorney anticipates significant unpredictable complexity.
A first-offense standard DUI conviction runs $8,000-$15,000 total: $2,500-$5,000 attorney fees, $2,300 in base fine plus surcharges, $500-$800 court costs, $500-$1,200 alcohol screening and counseling, $1,000-$1,500 ignition interlock over 12 months, $200-$400 MVD reinstatement, plus $800-$2,000/year SR-22 insurance for 3 years and probation supervision fees. Extreme DUI increases the total to $12,000-$20,000.
Yes, most Arizona DUI defense firms offer payment plans. Common structures include: 2-3 installments over 30-60 days (typically 50-60% upfront, remainder before trial); extended 3-6 month payment terms with modest administrative fee; third-party legal financing (LegalFee Financing, Trucanto) at 12-24% interest; credit card payment; and home equity or personal loans for higher-fee felony cases. All fee arrangements should be documented in a written engagement letter.
Usually not, because cheap DUI representation typically means high case volume with limited individual attention, no suppression motions, no expert witnesses, and higher plea outcomes. Studies of Arizona DUI outcomes show reduced-charge and dismissed cases correlate with experienced representation. A $5,000 attorney who negotiates Extreme DUI down to standard DUI saves 20 days of mandatory jail (worth $8,000-$15,000 in lost income), 6 months of interlock, and 3 years of higher insurance rates.
Yes, most reputable Arizona DUI defense attorneys offer free initial consultations, typically 30-60 minutes in person or by phone. Free consultations should include a review of your specific case facts, an assessment of likely charges and outcomes, a written fee quote, and answers to your questions. If an attorney charges for the initial consultation or refuses to quote a fee without additional payment, consider that a warning sign about transparency.
