How to have Adobe trust your Notary-Owned Individual Digital Certificate

For notaries with their own digital certificate, here are steps you can take to ensure Adobe trusts your signature.

In certain states, such as Kentucky and Texas, notaries may use their own individual Digital Certificate, instead of the SIGNiX digital certificate, which can be purchased from a third party provider, like IdenTrust for example.

For more information on how to upload your own digital certificate, please see this article.

The digital certificate helps validate a signature on a digitally signed document, when viewed in a PDF reader program such as Adobe. 

Adobe has what is call the "Adobe Approved Trust List" ( AATL) and most individually purchased digital certificates are not on that list by default.
To ensure that your signatures show as valid when a signed document is opened in Adobe, you and anyone that is accepting the signed documents from you will need to manually trust the certificate.
