Can an Electronic Release of Liability uphold as well as a hand signed copy? Let me fill in the blanks. I sell aircraft plans for a Non-Profit 501(3)c organization. Currently the purchaser has to hand sign and have notarized the Release of Liability and then sent to me before I will ship the plans. I was thinking about offer the plans through PayPal via our website to make it easier to order the plans. Is there a way to do the release of liability online instead of having to have the hard copy? Does it really make a difference since I am not sure either would really hold up in court?
