RCM on professional bills

As per Notification No 13/2017, RCM is required to paid against services of Advocates.
So if you are paying Fees to an Advocate, then you are required to pay RCM against that fee.
But if you are paying Fees to a CA, CS or any other professional other than Advocate, then the requirement of paying RCM does not arise.

Thanks

No RCM Applicable . provided that the professional hire has not raised bill in capacity of Lawyer.

Yes I do agree with @ Pankaj Rawat ji. Moreover you can check the notification mentioned in my above reply.
