# Cosigning Inventory in a Final Disposition
## Lean how to add a cosign for inventory that has already been destroyed or returned to the sponsor.
Verify users are able to cosign stamp to items that have already been destroyed or returned to sponsor. The stamp is visible on Certificates of Destruction, as well as the Inventory DARF.
Adding a Cosign can only be done to inventory that already has a final disposition. It cannot be added before the inventory is destroyed or returned to sponsor.
If you are wanting to Authorize a Destruction or Return to Sponsor, please check out this article. Authorizing happens before a final disposition is recorded by the IDS pharmacy.
