i had made an appointment with an attorney to find out what would it cost to hire her services as a corporate attorney with a business i might get involved. and she told me before she can quote me a price she has to get mi signature. next thing i receive a bill for over $5000 stating that was her retainer money. i told her that i did not get involved with that business and do not owe her anything. she has threaten to sue me. can she do that and how much she can get from me?
