So, it's simple: you attach an electronic signature to an electronic document and off it wings by e-mail. Job done, right? Apparently "some businesses are still unsure if electronic signatures would satisfy legal requirements," says The Law Commission. But instead of just saying "of course, in the absence of fraud or some other frustrating or negating matter, that's a validly executed document" the Law Commission has produced "proposals." So, not simple at all, then.
