Tips for interacting with your M&A Lawyer
If you want your lawyer to be responsive, respond quickly to him/her. If it is a question, you want to get them before they go onto the next project.
The reality is, a good M&A lawyer is very busy. It is hard to find a good M&A lawyer who is not busy. I have fired clients that are unreasonable and the M&A law community is very small. Don't be a dick.
