Hi,
I need to file for a divorce, in which I'm doing my own paperwork. How do I ensure that he receives the proper paperwork? What documents will I need to send?
The same documents that you'd need if he wasn't incarcerated.
When you've prepared your petition and filed it with the court, hire yourself a professional process server who is experienced with serving court papers on incarcerated people. He'll figure out how to get it done.
