A flat fee for a Washington impaired driving defense can mean five different things, so here is how to read one quote closely and put a second on the same footing.
Two attorneys will quote two numbers for what looks like the same case, and the gap between them is rarely about skill. It is about scope. One number may cover everything from the first appearance through a jury verdict, and the other may cover the arraignment, a handful of hearings, and a plea, with trial priced separately when and if it arrives. Neither approach is wrong. The problem is that a reader comparing the two on price alone is comparing a whole case to a portion of one, and paying a retainer before working out which is which is a decision that is hard to reverse.
What the phrase flat fee is actually doing in the sentence
A flat fee means the price does not move with the hours, not that the price covers every stage. Most Washington fee agreements draw a line somewhere, and the useful question is where. Common inclusions are the arraignment, pretrial hearings, review of the discovery packet, and negotiation with the city or county prosecutor. Common exclusions are the Department of Licensing hearing, expert witnesses, an independent review of the breath test instrument's maintenance records, investigator time, and the trial itself. Ask for the line to be pointed out in the document rather than described over the phone, because the document is what governs later.
The licensing hearing is the first place quotes diverge
The administrative case runs on its own clock and its own rules, and it is frequently priced as a separate engagement, sometimes at a few hundred dollars and sometimes at a figure approaching a third of the criminal fee. A quote that appears cheap may simply have left the hearing out. A quote that appears high may have folded it in, along with the subpoenas for the arresting officer and the time spent reading the officer's report against the standardized field sobriety testing protocols that the National Highway Traffic Safety Administration is responsible for maintaining. Ask each attorney the same plain question: is the licensing hearing inside this number, and if not, what does it cost.
Suppression motions, and who decides whether one gets filed
Contested motions are where the real work sits in most impaired driving defenses, and they are also where fee agreements get vague. A motion to suppress the stop, the field sobriety tests, or the breath result requires briefing, a hearing, and often live testimony, which is many hours of work for a fee that may or may not have anticipated it. Some agreements include one motion hearing and price additional ones separately. Some include all pretrial litigation. Some are silent, which in practice means a conversation later, at a bad moment. Ask whether filing a suppression motion changes the fee, and ask who makes that call.
Putting the second quote on the same footing
Comparison only works if the questions are identical, so write them down before the first consultation and read from the same page at the second. Six questions do most of the work: what stages are inside this fee, what triggers an additional charge, is the licensing hearing included, is trial included and at what price if not, what costs are passed through rather than billed as fees, and what happens to the money if the case resolves at the first hearing. Ask each attorney to answer in the fee agreement itself. The answers, side by side, usually explain the entire gap between the two numbers.
Costs, refunds, and the parts nobody quotes
Fees and costs are different categories, and a well-drafted agreement separates them: filing fees, records requests, interpreter time, deposition transcripts, and expert reports are typically passed through at cost. Read the refund clause carefully, because a flat fee earned on receipt behaves differently from one earned in stages, and the difference matters if the case ends early or the relationship does not work out. Ask whether an early resolution returns any portion. Ask what an appeal of the licensing decision to superior court would cost. The attorney who answers those questions in writing, without hedging, has told you something useful about how the rest of the representation will run.
The retainer check is usually the largest single payment in the case, and it is written at the point when the reader knows least about what the case will require. An hour spent reading two agreements against each other, with the same six questions applied to both, converts a guess into a comparison. That hour is available now, and it will not be available after the money moves.
