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.
