Working with a new appellate attorney should feel structured. Here's how the first two conversations with Tammy usually go, from the moment you request a consult to the day representation begins.

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

• How much does it cost to hire Tammy for a appellate case?

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

• Does Tammy offer a free consultation?

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

• How long do appellate cases in Oklahoma typically take?

  Simple appellate 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. Tammy gives a realistic estimate for your facts at the consult — vague answers here are a red flag.

• Can Tammy take my case if I'm outside Tulsa?

  Tammy is licensed in Oklahoma. Matters governed by Oklahoma law are the natural fit. Out-of-state matters are handled case-by-case, sometimes with local co-counsel. Ask during intake — Tammy 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 Tammy?

  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. Tammy will filter what matters — over-preparing at intake is always cheaper than needing a second meeting.

• Is Tammy accepting new appellate clients right now?

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