This page will outline the steps necessary to setup the ability to digitally sign documents that require a signature using Acrobat Pro.  This process serves as an official and legally binding signature which can be used when you are unable to physically sign a document.  If you do not have Acrobat Pro and need assistance digitally signing a document, please send an email to detailing what you need and OIS will attempt to assist you further.
