To set up a waiver or refund policy acknowledgement for your ticket event, go to Event >. Waiver/Refund Policy. You can add up to 3 waivers. 

If you set up a waiver for your ticket event, you can generate a time-stamped version of the waiver. This is useful if you need to confirm that a "no refunds" waiver was signed by a ticket purchaser.

To view the signed waiver, navigate to Reports >> Ticket Purchases. Search for the ticket purchases name and then click "Manage". You will then be able to see the time stamp of the waiver signed. This information appears when you click the down arrow to the right hand side of the purchase date.
