Here in Kali, the court reported lobby is VERY strong. There have been some experiments in electronic recording of court proceedings, but I can't remember the last time I was in such a courtroom.
I occasionally take a video deposition when somebody is not going to be around for trial, and I ned the jury to SEE them.
Problem with video/electronic is in it's intended use. In a printed depo, I can find and read the key question and answer and go right to it, I haven't seen video with that capability, plus I still have to pay for a reporter to transcribe it anyway.
In will and prenuptuals, however, I understand that there is an increasing use of video to film what occurred when the 20 year old bippy marries the rich 55 year old and signs paper that says she agrees to a set amount in case of a divorce. Don't know what the market/provider situation is like, maybe call some lawyers in the book and ask them what they think.
Good luck.
