Are they worried that if it was on a computer and they had to click "OK" they might not read the details?
I really don't know. But there is certainly a mindset in most law offices that every decision needs to be papered and every paper needs a file. The Paperless Law Office is very easy in concept and damn near impossible in practice.
And I am not saying this from upon high. I have worked remotely for most of my clients for over 10 years. None of them have required paper documentation of the work I do for them, and all of the work could be retrieved from multiple electronic sources and backups of those sources. And yet my office is covered in mounds and stacks of paper and I am routinely printing and scanning stuff. There are certain things that I simply do better on paper, or at least I think I do.
