Since March 2020, our Zoomers have worked remotely and reported an overall better work-life balance with more time for family and personal wellness.

At the end of 2021, LegalZoom made the official commitment to being a remote-first company. Remote-first means that there is no expectation that Zoomers come into an office for a fixed number of days outside of those employees identified as essential onsite workers.
