Full story: I am close to a contract dispute with my landlady (she refuses to keep the heat at the legal minimum level because it would be too expensive for her, and threatened to evict us when I mentioned the law) and anticipate needing legal help soon.
If you don’t know a lawyer, maybe you know someone who knows a lawyer. Or maybe you have heard one on local TV and they sounded particularly professional and smart. Or maybe you call one at random. Even a mediocre lawyer can tell you who the good lawyers are.
The more people you talk to, the more you’ll be able to detect the rockstars from the BS. Although, you don’t necessarily need a rockstar to handle uncomplicated legal matters.
It’s like if your stomach hurt you might call a gastroenterologist but then he says sounds like something a dietician can help with and tells you someone they recommend. Same thing happens in the legal world.
More particularly for this question, while the state bar can be okay for referrals, you probably want someone who has worked in labor & employment law, or someone familiar with equity agreements if equity/stock is a meaningful component of the comp (look for a "startup lawyer" or "emerging companies lawyer"). Both of those will be familiar enough with the IP issues and general contract provisions. You'd probably only want an IP specialist if you're specifically licensing prior inventions (or you have IP-heavy side projects that you want to exclude).
Good luck!
The first time I needed a lawyer to review business paperwork, I called a local personal injury lawyer who I knew had a good reputation, and they gave me a reference to someone who barely had any marketing presence at all, but was an excellent lawyer. 10/10 would do again.
