You can create a new deposition from a case's document page.
Click NEW in the upper-left corner, then choose Deposition.
In the Add Deposition window, enter the Deponent name and a Deposition Date — both are required. If you don't know the exact date yet, enter your best estimate; you can change it later. You can also add an optional Reference Number.
Then choose Host or Participant:
Host — you or someone at your firm is the taking attorney and will host the deposition.
Participant — you'll join this deposition as opposing counsel or an observer.
Click Create Deposition. The new deposition appears in the Depositions list in the left-hand panel. (The Host/Participant choice locks once the session starts.)
