How to choose a business lawyer
- Check the lawyer’s status and any public discipline in the state bar or law society directory.
- Ask how many business law matters the lawyer handles each year, and who at the firm will do the work.
- Get the fee arrangement in writing: hourly, flat or contingency, and which costs are charged on top.
- Ask how and how often the firm will update you, and how fast it answers calls and emails.
- Read recent reviews for how the firm communicated and billed, not only for outcomes.
- Ask for a written estimate or flat fee for a defined piece of work before it starts.
- Meet more than one firm; many offer a short first consultation, sometimes free.
Questions to ask a business lawyer
- How would you approach a matter like mine, and what are the realistic options?
- How do you charge, and what will the total likely cost?
- Who will be my main contact, and how quickly do you reply?
- Which of my contracts most need a review?
- Can you work on a flat fee or a monthly retainer?
- Is there any conflict of interest that would stop you representing me?
Terms explained
- Contingency fee
- A fee that is a share of the money recovered, paid only if there is a recovery. Common in injury cases; not allowed for criminal defense or for securing a divorce.

- The search a firm runs before taking a matter to make sure it does not represent someone on the other side.
