The family court judge has has given us the order to impound his passport. But unfortunately I do not have eiethr his passport number or the information about the issuing authority of his passport.. We need to get the relevant details so that the summons can be served to the right office and our papers do not get lost and hence the judge has told us to provide all the details.. Please let me know: 1)Whether the passport office is in a position to give the passport number and other details of the Indian citizen on we providing his name, given surname, father's name and his date of birth. 2)Whether the passport office is in a position to state the place or the country where the person is presently located and if not which office / department of the Central Government be able to help us out in seeking this information. 3)Will the Immigration Office at Mumbai be able to provide these details as where the person is and when has he left India? 4)Also need to know which department undertakes impounding of the passport and where the office of such departments situated and who is the concerned person to be contacted. Can one of you experts or someone with prior experience with this can please guide me.. Many Thanks. ABC
