Hi - my name is XXXXX XXXXX I'm a Personal Injury litigation attorney. Thanks for your questions. In order to keep the responses straight, I'll list your question and then my response to each.
1. If there are numerous defendants in a Federal Civil case and two defendants have the same attorney who files a motion to dismiss for just those two defendants, would a response to the motion need to be sent to ALL (numerous) defendants or just to the attorney of record who filed the motion ?
The attorney of record for every party (plaintiff and defendants) would need to be sent a copy of the response to the motion for summary judgment. Even if another defendant isn't involved in the motion, he/she is still entitled to a copy of the motion via his/her attorney.
2. When sending responses, is certified mail required or can regular first class mail be used ?
Regular first class mail is sufficient; certified mail is not required. When you send in your response, you will attach a "certificate of service", which says that you mailed the response via first class mail. This certification is the only thing you'll need.
3. After serving the summons, can discovery requests be made immediately or does the court ( US District - Civil ) set up a hearing for discovery plan, or what ?
Discovery can be issued any time. The judge will enter a scheduling order, but that only sets for the the DEADLINES for discovery, motions, expert witness disclosures, etc. - - NOT a starting date. Thus, there's no requirement to wait on issuing discovery until after a motion to dismiss is determined.
Please let me know if you have any additional questions.
