Two DUI Quotes, Thousands Apart? Read What Each Fee Is Actually Attached To
A flat fee, an hourly rate and a staged retainer can cover very different work. Here is how to read what a criminal defense quote is priced against before you sign it.

Two offices quote the same arrest, and the numbers are nowhere near each other. That gap is rarely about talent, and it is almost never about confidence. It is about what the fee is attached to: a stage, an hour, an outcome, or a vaguely described case that nobody has defined in writing. A quote is a price per unit of something, and if the unit is undefined, the price cannot be compared to anything. The work of choosing counsel after a drunk driving arrest begins with pinning down the unit, in writing, before money moves.
Three ways the same case gets priced
The flat fee per stage is the most common structure in misdemeanor defense. A fixed number covers everything through arraignment and pretrial motions; a second, separately stated number covers trial. The split exists because the trial phase is where hours become unpredictable, and a single all-in flat fee either overcharges the ninety percent of cases that resolve before trial or quietly underwrites the ones that do not. Hourly billing attaches the fee to time, which is honest but hard to forecast. Hybrids attach a deposit to a stage and then bill time against it, which is the arrangement most likely to be misread by a client who heard the deposit and stopped listening.
None of the three is inherently better. What separates a good engagement from a barely adequate one is whether the letter names the trigger that moves the case from one price to the next. A good letter says the trial fee becomes due when the case is set for trial, or when a particular motion is filed, with a date-certain definition. A thin letter says trial is quoted separately and leaves the moment of separation to a phone call you will have while under pressure.
What changed, and why the old flat fee stopped fitting
The work underneath a drunk driving case has gotten heavier in a specific, documentable way: there is far more recording to review. Patrol video, body-worn cameras, booking room footage and in-car audio now arrive as hours of material that somebody has to actually watch, and watching is not something that can be skimmed. Add toxicology: blood draws go to a laboratory, and in many jurisdictions the queue for results runs long enough that the criminal case moves forward for months before the number arrives. A fee quoted against a case that would be fully known at arraignment no longer describes the case anyone is handling.
The measurement side has tightened as well. Breath testing instruments rest on a chain of calibration and traceability, and the National Institute of Standards and Technology is responsible for the underlying measurement standards that chain refers back to. Challenging a result means requesting maintenance logs, calibration records and operator certifications, then having somebody competent read them. That is discrete, billable work that older flat fees often folded in silently and newer ones increasingly break out. Offices that broke it out are not charging more for the same thing; they are showing you a line that was always there.
The license case is a second matter, and it has its own clock
An arrest typically starts two proceedings. One is criminal, in court. The other is administrative, run by the state licensing agency, and it is the one that suspends driving privileges regardless of what the court eventually does. The administrative side runs on a short request deadline measured in days from the arrest, not weeks, and missing it forfeits the hearing outright. Many of these hearings are now conducted remotely by telephone or video, a change that stuck after it was adopted out of necessity, which has shortened travel time without shortening preparation.
Here is where quotes diverge most and clients notice least. Some fees cover the criminal case only; some include the administrative hearing; some include requesting the hearing but bill the hearing itself separately. When you ask a dui attorney in seattle for a number, ask in the same breath whether the license hearing sits inside it, and whether the firm will file the request in time if you sign on day six. A good office answers that before you ask. A barely adequate one answers only when prompted.
Fees, costs and the things that are nobody's fee
Costs are not fees, and conflating them is how a budget goes wrong by a four-figure margin. An expert witness on blood testing or field sobriety administration bills independently. Transcripts of a hearing, subpoena service, investigator time and records retrieval are advanced or billed through. Downstream of the case entirely sit the obligations that follow a conviction or a negotiated resolution: ignition interlock installation and monthly monitoring, alcohol evaluation, treatment or education programs, license reinstatement charges and the insurance consequences. None of those are legal fees. All of them are money you will spend, and a defense office that walks you through them at the consultation is giving you the real shape of the year, which is more useful than a low headline number.
Ask for the costs paragraph specifically. It should say who advances them, when they are billed, and whether you are asked to approve anything over a stated threshold. A clause requiring your written sign-off before an expert is retained protects both sides, and its presence tells you something about how the office runs.
Putting two quotes on the same footing
Comparison only works once both quotes describe the same scope. Write down four questions and put them to each office in the same words: what does this number cover, what ends it, what is the next number, and what is excluded entirely. Then ask what happens to unearned funds if you change counsel or the case is dismissed early, because a refundable-on-a-stated-basis clause is standard practice and its absence is a finding. Ask how you will be billed and how often, since a monthly statement showing work performed is the only way to verify that an hourly or hybrid arrangement is tracking the way you were told it would.
The office that gives crisp answers to those four questions is usually the one that has thought hardest about staffing the case, and the clarity of the engagement letter tends to track the clarity of everything that follows it.
Get the letter, read it somewhere quiet, and mark every sentence that names a trigger, a date or a dollar amount. Those are the terms that will govern the next several months; everything else is description.
