How to get call history of other person

This feature is available in all phones.search and find.

I want call history of other person for operators. So what are legal process to receive call history of other person 

That call history of another person is purely personal in nature and amounts to invasion on privacy of that individual.  Only law enforcement authorities with higher designations can seek such data by making such applications to service providers as prescribed under law.

Is the matter pending in the Court? If so, you can seek production of the said document/information from the concerned Telecom operator.

-Make the court get it for you. Make the judge pass an order to get a copy of the call records/anything you need.
