Back in the dim ages, otherwise known as the 20th century, I was a notary public. It came in very handy at the law firm I worked at, where notarized documents were pretty common. I would need to confirm the identity of the party or parties signing the document, and notarize it accordingly.
Today I learned (courtesy of Carl Malamud) you no longer need to be in the same room with the notary to have a document notarized. The Commonwealth of Virginia passed legislation in 2011 allowing for properly certified notaries to notarize documents via a video call. The Full Faith and Credit Clause of the Constitution along with relevant state laws will allow for the recognition of a document legally notarized remotely.
While not likely as pleasant a thing to do as getting married via video call, there’s one more thing you can do without leaving the house. Yay?
