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

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

• How much does it cost to hire Sonja for a business case?

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

• Does Sonja offer a free consultation?

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

• How long do business cases in California typically take?

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

• Can Sonja take my case if I'm outside San Francisco?

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

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

• Is Sonja accepting new business clients right now?

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