Colin discusses fees during intake so the arrangement fits the matter. Contingency, hourly, and flat-fee options are all common in government practice — ask which fits.

• How much does it cost to hire Colin for a government case?

  Cost depends on the type of matter, the fee model (contingency, flat, hourly), and how contested the case becomes. Colin walks through the likely range during the consult so there are no surprises.

• Does Colin offer a free consultation?

  Colin charges for the initial consult; that fee is credited toward representation if you retain Colin's office. Some government attorneys offer free consults — check Colin's current terms during booking.

• How long do government cases in District of Columbia typically take?

  Simple government matters can wrap in a few weeks; disputed cases can run 6–18 months from intake to resolution, longer if the matter goes to trial. Colin gives a realistic estimate for your facts at the consult — vague answers here are a red flag.

• Can Colin take my case if I'm outside Washington?

  Colin is licensed in District of Columbia. Matters governed by District of Columbia law are the natural fit. Out-of-state matters are handled case-by-case, sometimes with local co-counsel. Ask during intake — Colin will tell you if the case is a fit or refer you to someone closer to your court.

• What should I bring to my first meeting with Colin?

  Bring every document that touches the dispute: contracts, correspondence, police or medical reports, filed pleadings, invoices, photographs, insurance letters. Also bring a written timeline of what happened, in your own words. Colin will filter what matters — over-preparing at intake is always cheaper than needing a second meeting.

• Is Colin accepting new government clients right now?

  Colin's intake status shifts week to week. Submit the form; the office will confirm availability or refer the matter out.
