Adobe Sign compliance with India IT law

A post on helpx.adobe explains, "Adobe has engaged eMudhra, which is a CA, to issue digital signatures that are recognized under the IT Act. Hence, a document signed using Adobe Sign carries the presumption of validity on this count."  https://helpx.adobe.com/sign/using/legality-india.html

If I already have Adobe Sign, do I need to register with eMudhra or change any settings in Adobe Sign to ensure the digitial signatures are issued by eMudhra when necessary? Is there a way to prove to authorities that the digital signatures were issued by eMudhra or that Adobe Sign and eMudhra have engaged in a way that makes the digital signatures valid (for apporpriate contracts)? 

Thank you!
