Documents issued in one country which need to be used in another country must be authenticated and legalized or Apostilled before they can be recognized as valid in the foreign country. Such documents range from degrees, transcripts, powers of attorney and other legal papers. If the country where you intend to use your documents is a member of the Hague Convention, you need you documents attested by the Indian Ministry of External Affairs (Apostille). A duly Apostilled (Attested by the Indian Ministry of External Affairs) document is acceptable mostly in all Countries.
Apostille (Attestation by the Indian Ministry of External Affairs) can be obtained on birth certificates, death, power of attorney, marriage certificates, educational certificates and affidavits. Before getting the Attestation by the Indian Ministry of External Affairs all the concerned documents must be legalized and authenticated .
If it is a requirement NDVO would have asked when scrtinising the documents. Further subsequent to the Supreme Court Direction to All State Governments to make necessary Acts making the marriage registration compulsory. 2009 onwards
registration is compulsory. NDVO can get the document scrtinised through their agents if they have any doubt on those
documents. If essential this would have been asked specifically by CIC. Hi sunsweet, thanks for explanation. ..
Under this backdrop I feel it is not necessary.
