Digital signatures have legally been the same as written since I believe around 1998. The problem with most of them though is they generally accept a generic e-signature instead of something unique. I wonder how much it would actually hold up if someone later said they didn't actually sign it. The other party would have the burden of proving that it was signed and the cost in proving this doesn't seem worth it.
That said, I don't even worry about it and I generic e-sign all of them that request it.
I think what has to happen with e-signatures is that the entity has to prove that they have consistent processes and best practices in place and be capturing the appropriate data when doing so. I suspect that they have you create an account at some point in the process. That account is validated using a common set of principles. They don't just send out an e-mail, have you click a link and say "I sign"..., do they? Otherwise, it is just indicating that the person that clicked the link is signing the document.
The risk seems to be pretty low for the cost savings that they enjoy from e-signatures. So they are likely willing to take the small added risk to reap the cost benefits.
What are your thoughts about printing out the documents, signing them and scanning them and emailing back?
I am usually good with that, but I purchased a unit that wants my Social Security number and credit card number and I am leary about giving scanning it and sending it through email.
In my closing, I had to supply drivers license and SSN. I scanned the DL and sent electronically. I told the closing agent I would not send the SSN via email, and I think he just had me put it on the hard copy closing docs under my signature. YMMV.
I refused to supply my SSAN on my last two purchases and was told that I didn't really need it and everything proceeded without it.
