Texas has allowed Remote Online Notarizatrion (RON) to be done remotely over video call since July 1st, 2018. This is something that can save time and gas for everyone involved. You just need a digital copy of the document you need notarized, a form of photo identification like a driver's license, and an internet connected device with webcam (it can even be your phone!).
