Yes, if the papers have been filed with the court then you have to be served by an agent of the court, in person. This is the same in all states as far as I know. Who sent the papers to you? If they came from her L then they may just be for your review and they haven't officially been filed yet. I know it's a real gut punch to get those papers, but hang in there, it'll pass!
Thanks, even though it doesn’t feel like it right now.
Her L sent these papers to me. I emailed my L last night soon after opening them asking about the next steps (obviously a response, but what specifically that would look like).
