The North Carolina Disciplinary police are dinging Perry W. Martin for hitting on a divorce client during his representation of her. Since Mr. Martin was admitted to the bar circa 1050 that would make him about as old as Moses. Here's the two-page opinion courtesy of the Legal Profession blawg.
According to the opinion, Martin asked his client what "each button" on her top would cost to unbutton, and he promised her that they would sexually explore everything they could think of, if she spent the night with him. Of course, the answer to the first question was, his license. By the way a quick look at Google came across the following comment from a former client, "he should have retired 30 years ago."
Do not screw the client. Clients are vulnerable, especially divorce clients. If as a young practitioner, and you don't think you can control your sexual impulses, choose another area of law. Even the client who "thinks" she wants a romantic relationship with "irresistible you" will come to her senses and you, my friend can find yourself looking like a real jerk in the disciplinary docket.
