I'm about to dismiss a defendant in a civil unlimited case. His laywer that has been particularly hard to work with. (I dealt with the lawyer of another defendant so I have a basis for comparison). It has gotten to the point I don't trust that lawyer anymore. AFter a long delay, the lawyer has sent me an email stating their client has agreed to "waive costs and malicious prosecution" (doesn't even say "action"). Is that sufficient? Seems like I would need something a little more official. Are there any rules about what info should be on it? specific wording? format? means of communication (i.e. is email just as acceptable as U.S. mail? etc) Anything else I shoudl keep in mind before I grant this dismissal?
