That depends on how the file is delivered. Drawing your signature is not even needed. That said, most of the times I need a signature is some bureaucratic useless form and the signature is just a pro-forma - and you can be sure if I don't have a signature (and maybe if I didn't pass my form through a filter to make it look like it was scanned) some government employee in some office will reject my form and I'll have to do another one and fork out even more money.
