To sign a document, you may be asked to first upload a digital signing certificate issued by a recognised certification authority in your applicable jurisdiction(s) to the platform. For the avoidance of doubt, Boardlogic is not a certification authority of digital certificates, and we do not validate the legality and applicability of any signing certificates uploaded to the platform. 

1. Navigate to Account > My Settings

2. Click on Signing Certificate under Signature Settings

3. Upload a signing certificate in .pfx or .p12 format and add a description, then Save

Some organisations may accept self-signed digital certificates for handling documents. Adobe allows you to create such a certificate for free. For step-by-step guide, please visit for reference.
