Some people call this 'superlegalisation'. There are designated authorities in every country to issue apostille certificates or legalisation. Apostilles are commonly issued for various documents related to adoption cases, for commercial documents, for official documents related to vital statistics, and for court records, land records, school documents and patent applications.
We provide certificate attestation services for Oman, Kuwait, Qatar, Bahrain,Saudi Arabia (KSA), and United Arab Emirates (UAE) from various departments like Notary, GAD, State Home Ministry, SDM, Human Resource Development Department(HRD), Ministry of External Affairs (MEA), Embassy and Consulate for all kind of certificate attestation requirements like business visit visa, employment visa or family visit visa or family resident visa, Driving License, etc.......
In case of personal documents, Home Department/General Administration Departments are the designated authorities. In case of educational documents, State Governments have now opened Regional Authentication Centers (RACs) at various States from where the document should first be attested. Documents attested by these authorities then need to be presented to MEA for attestation prior to Embassy Authentication.
This is a process in which various seals are placed on the document. Documents issued in one country which need to be used in another country must be "legalized" before they can be recognized as valid in the foreign country.
