Obtain Marriage Certificate

What is a Marriage Certificate and Why is it Needed?
A Marriage Certificate is the proof of registration of a marriage. The need for a Marriage Certificate arises in case you need to prove that you are legally married to someone, for purposes like obtaining a passport, changing your maiden name, etc.
Legal Framework

In India, a marriage can be registered under either of the two Marriage Acts: the Hindu Marriage Act, 1955 (External website that opens in a new window) or the Special Marriage Act, 1954 (External website that opens in a new window). To be eligible for marriage, the minimum age limit is 21 for males and 18 for females. The parties to a Hindu marriage should be unmarried or divorced, or if previously married, the spouse by that marriage should not be alive. In addition, the parties should be physically and mentally healthy and must not be related in a way prohibited by the law.
The Hindu Marriage Act is applicable only to the Hindus, whereas the Special Marriage Act is applicable to all citizens of India.
The Hindu Marriage Act provides for registration of an already solemnised marriage। It does not provide for solemnisation of a marriage by the Registrar. The Special Marriage Act provides for solemnisation of a marriage as well as registration by a Marriage Officer.

What You Need to Do to Obtain a Marriage Certificate
Under the Hindu Marriage Act:

Parties to the marriage have to apply to the Registrar in whose jurisdiction the marriage is solemnised or to the Registrar in whose jurisdiction either party to the marriage has been residing at least for six months immediately preceding the date of marriage। Both the parties have to appear before the Registrar along with their parents or guardians or other witnesses within one month from the date of marriage. There is a provision for condonation of delay up to 5 years, by the Registrar, and thereafter by the District Registrar concerned.

Under the Special Marriage Act:

The parties to the intended marriage have to give a notice to the Marriage Officer in whose jurisdiction at least one of the parties has resided for not less than 30 days prior to the date of notice. It should be affixed at some conspicuous place in his office. If either of the parties is residing in the area of another Marriage Officer, a copy of the notice should be sent to him for similar publication. The marriage may be solemnised after the expiry of one month from the date of publication of the notice, if no objections are received. If any objections are received, the Marriage Officer has to enquire into them and take a decision either to solemnise the marriage or to refuse it. Registration will be done after solemnisation of the marriage.
Any marriage already celebrated can also be registered under the Special Marriage Act after giving a public notice of 30 days, subject to conditions. However, as stated above, the bridegroom and the bride must have completed 21 years and 18 years of age respectively.
