Final answer:
Sub-registrars can receive but not issue marriage certificates. They are typically involved in recording official documents. The issuance of marriage certificates is managed by other local or state authorities.
Step-by-step explanation:
Sub-registrars have the authority to receive but do not issue marriage certificates. Their role typically involves the process of recording and maintaining official documents and transactions such as property deeds, partnership deeds, wills, and powers of attorney.
When it comes to marriage certificates, a sub-registrar may authenticate and keep records of the certificates, but the issuance of these documents is usually the responsibility of a different authority, often at the state or local government level. It is important to understand that the specific functions and responsibilities of a sub-registrar can vary by jurisdiction.
