For overseas marriage registration, the exact documents depend on the country where the marriage is being registered and whether one or both spouses are Indian citizens. Generally, you may need:
Valid passports of both spouses
Visa, residence permit, or proof of legal stay, where applicable
Birth certificate or other age-proof document
Address/residence proof
Passport-size photographs
Marriage invitation card and/or wedding photographs, if applicable
Original marriage certificate issued by the foreign authority, if the marriage has already taken place
Proof of marital status, such as a single-status affidavit or certificate
Divorce decree or death certificate of a previous spouse, if either person was previously married
Witness identification and address documents, where required
Affidavit/declaration regarding marital status and eligibility to marry
Certified translations of documents if they are not in the required language
Apostille or attestation of foreign documents, if required by the relevant authority
The Indian Ministry of External Affairs advises keeping copies of the marriage certificate, passports, visas, wedding photographs and other important marriage-related documents. Requirements can vary significantly between countries and between registration through a local authority and an Indian Embassy/Consulate.
Important: Before submitting the application, check the specific document checklist of the foreign marriage registrar or the relevant Indian Embassy/Consulate, because additional documents may be required.
