Why Cowan Kirk

A DUI charge in Washington can cost you your license, your job, and thousands of dollars — and it stays on your record. The outcome depends almost entirely on the quality of your defense attorney. Cowan Kirk has been doing this since 1969. They don't dabble in DUI defense alongside other work. They are DUI defense. Their attorneys authored the leading textbook on defending these cases in Washington, which means they understand the science of breathalyzer machines, field sobriety tests, and police procedure at a level most lawyers simply don't reach. If you're charged with a DUI in the Puget Sound area, this is the most specialized firm available.

Client Reviews

Client
Brian S.
DUI Defense — Charges Reduced
★★★★★
"I was pulled over on 520 and charged with DUI. Cowan Kirk challenged the breath test administration and the stop itself. My charge was reduced to negligent driving. Without them, I'd have a DUI on my record."
Client
Keisha A.
DUI — License Saved
★★★★★
"I needed my license for work — losing it wasn't an option. The team at Cowan Kirk handled the DOL hearing and the criminal case simultaneously. I kept my license and the criminal charge was dismissed."
Client
Tom L.
Second DUI Offense
★★★★☆
"This was my second DUI and I was terrified about jail time. Cowan Kirk knew exactly what arguments to make, what evidence to challenge, and how to present the case. The outcome was far better than I expected."

Frequently Asked Questions

What is the DOL hearing and why does it matter?
When you're arrested for DUI in Washington, the Department of Licensing (DOL) automatically initiates a license suspension. You have only 20 days from your arrest to request a hearing to challenge it. If you miss that deadline, your license is suspended automatically. Cowan Kirk handles both the criminal case and the DOL hearing simultaneously.
Can a DUI charge be dismissed or reduced?
Yes. DUI charges can be challenged on many grounds including the legality of the traffic stop, proper administration of field sobriety tests, breathalyzer calibration records, and officer conduct. Cowan Kirk identifies weaknesses in the state's case and uses them to seek dismissals, reduced charges, or favorable plea agreements.
What are the penalties for a first DUI in Washington?
A first DUI in Washington can result in jail time (minimum 1 day, up to 364 days), fines exceeding $5,000 including fees, license suspension of 90 days to 2 years, mandatory ignition interlock device, and required alcohol/drug treatment. An experienced attorney can significantly affect these outcomes.
Does Cowan Kirk handle drug DUI cases?
Yes. Drug DUI cases — including marijuana, prescription medications, and other substances — are handled by Cowan Kirk. These cases often involve blood tests rather than breath tests, and the legal and scientific issues are different from alcohol DUI. The firm has extensive experience with both.
