The legal profession has embraced electronic signatures. At my work we use DocuSign for the majority of contracts with our vendors.
Not all participants in the legal profession have embraced e-sigs. For example, my wife and I needed to get a power-of-attorney (POA) so that I could a home purchase deal while she was out of the country. That was just a week ago. And the POA was required to be signed, in blue ink, before taking it to the court house.
Even in real estate, there are participants who, for one reason or another, still demand sigs. For the same property we are trying to close, the seller (a trust) required us to use ink signatures, which we found it very unusual since we have been doing e-sigs for ages.
For as long as someone demands an ink signature for something someone else wants, and there are now laws demanding e-signatures to be accepted when offered, we are going to have ink sigs. And that is going to be the case for a long, long time to come.
