What are the legal limitations of communicating with defendant's attorney via email? To expediate issues, I would like to use email vs snail mail but I don't know if it is legally "binding" (i.e., a request for permission to leave to amend)? Would I email and then follow-up with snail mail?
You do know that opposing counsel does not have to respond to your email requests, right?
In fact, even though state law might allow email communication, some large law firms have policies prohibiting such communication. Thus, the attorney has no say in the matter. The expedited process you seek, might become an unwanted delay or barrier.
So, in answer to your query, you can email anyone you wish, about anything you desire.
Another person (especially opposing counsel) does not have to respond, whether you email them or send them US mail. Unless, of course, it is pursuant to court order or trial procedures.
The court, of course, is not bound by attorney communication or agreement. The court calendar has more to do with the speed at which any litigation proceeds, than does attorney communication.
Are you an attorney, or are you representing yourself in a civil matter, pro se?
