While $100-$300 is a common range, $400 can be standard for experienced attorneys in complex fields or major cities, and even less experienced lawyers in big firms might bill similarly, with partners charging much more.

Can I legally publish a book written by AI?

What not to say to a lawyer?
You should not tell a lawyer to "just do it," admit fault (like saying "I'm sorry" or "it was my fault"), downplay your case ("it's simple/quick"), compare them to other lawyers, or lie or withhold information, as these undermine their ability to help you; instead, be honest, factual, and provide all details, even bad ones, so they can build the strongest case, letting them guide strategy.
