I would like to use AI to check the completeness and accuracy of contracts prepared by Professional Advisors and then sent to my company for signature via their Docusign account.

I need to ensure these Advisors, who work for different companies, each of which has its company-specific forms, have prepared the forms for my signature correctly and completely.

Is there a preferred approach  to accomplish this task BEFORE signing or can I only do it AFTER I have signed and returned the document and received a pdf copy of the fully executed contract in my Docusign account?  

Any guidance will be much appreciated.
