countersignature
Validating second signature
A countersignature is a second signature added to a document already signed by someone else, serving to authenticate or authorize it.
The countersignature confirms that the first signature is genuine or that the signer had proper authority: The check required the treasurer's countersignature before it could be cashed.
Common in legal, financial, and official documents where dual approval provides additional verification.
