No, not death - just another transmutation. I've done 3 so far. My suggestion: Read your state's notary statutes. If your state has adopted RULONA, read the sections pertaining to electronic signings - I understand from friends in other states that they do differ. (My state adopted a few really... unusual... amendments to the original; but that's standard up here.) If your state has not yet adopted RULONA, don't worry - you're safe.
Second, become familiar with e-documents and signing software. I have used DocuSign for several years, and knew that electronic signatures need to have a certificate issued for each prior to being considered legally binding on a contract. My signer in the second e-signing had neglected that step - I had to get the escrow agent on the line to get his signature certified before we could complete the signing. Pavaso has a product for signing professionals, and I expect most of the others do or will have soon.
Third, make sure your e-signing does not require a wet signature (notarized, of course) on some documents. My first did on the recordable docs. My second did, but only on the deed. My third did on all the critical docs. So read those instructions before you go out!!
If you are considering a laptop, I suggest one with a touch screen. You can avoid purchasing a signing pad and stylus.
