Today it is necessary to do a background check on your spouse before marriage. Not only about him or her but about their families as well. You can conduct these inquiries by Private Detective Agencies in India. Detective Agencies takes 7-10 days to gather all the information about the prospective groom or bride and their characters, social background, education history, habits, financial reputation, past broken or unbroken marriage, etc. and This has to be a discreet and confidential inquiry so that the concerned party should not know about this investigation and you will get 80-90% correct information.
