I received some discovery on a CD. I don't know what the attorneys did with their stuff on the CD, but I'd guess they did have to print it out and look it over.
I think it's delivered on a CD just to save paper or delivery charges.
You should definitely get a copy of it. My group just burned me a copy of the CD. I saw that a lot of the pages were useless and only printed those that were informational. It wasn't that hard to open up and read.
Mine sent his stuff in a highly disorganized manner, and did include extra things, no doubt to hike up bills.
I'm not sure how much of a face-to-face meeting you'll have, having had only one divorce to go through! With mine, I had to go through and organize things so that I could see what was missing. If you think there are errors and omissions with what your STBX sends, you'd want to point out that out.
Does that help?
