It varies somewhat. However, most DUI attorneys in the Seattle metro area will want at the minimum - half (1/2) or 50% of the DUI attorney fee down, up front or in advance. Obviously, it really depends on the attorney. My office offers flexible payment plans with as low as $1000 - $1500 up front or in advance if you qualify. Most DUI attorneys in Washington State charge flat fees for DUI representation. The flat fee typically includes all Court appearances with or without Jury Trial and the Department of Licensing (DOL) administrative Hearing. Some DUI attorneys will also charge in stages - a certain flat fee up to a certain point. (i.e. DOL, Motions, without Trial, with Trial) The good news with flat fees is that you know exactly what your attorney will cost you and you can plan accordingly.
