To edit a deposition go to that deposition's screen and click 'edit' next to the deponent's name. 

Or you can click 'edit' in the Depositions list in the upper right of your screen to reach the "manage depositions modal", then click Edit Deposition Icon next to the deposition you want to edit. 

Either way brings you to the edit deposition modal, where you can change deponent name and deposition date. 


Next: Manage Labels.
