In the sate of Michigan, do I have to have a proof of service when I am answering a complaint in District court? I was served a COMPLAINT from 90th District court. When I called the court and asked if I could fax my answer in to them, the told me yes and how to do that. My question is: Do I, and if so how, have to do a proof of service for this fax? I know I have to do a proof of service when I send my annswer to the Plaintiff. But I am not sure if I have to do one when I fax my answer in to the court.
