In India, court marriage is governed by the Special Marriage Act, 1954, which provides for the solemnization and registration of marriages between individuals of different religions or those who do not wish to perform a religious ceremony. The Act also allows for the registration of marriages already solemnized under personal laws. Here are some key points regarding court marriage laws in India:

1. Applicability: The Special Marriage Act is applicable to the entire territory of India except for the state of Jammu and Kashmir.

2. Eligibility: For a court marriage under the Special Marriage Act, both parties must meet the following criteria: a. The bridegroom must be at least 21 years old, and the bride must be at least 18 years old. b. Both parties must be of sound mind and capable of giving valid consent for the marriage. c. Neither party should have a spouse living at the time of marriage.

3. Notice of Intended Marriage: Before the marriage, a notice of intended marriage is required to be given in writing to the Marriage Registrar of the district in which either party has resided for at least 30 days before giving the notice.

4. Publication and Objections: After receiving the notice, the Marriage Registrar will publish it in the office, inviting objections to the marriage within 30 days. If no objections are received, the marriage can be solemnized.

5. Marriage Solemnization: The marriage can take place at the Marriage Registrar’s office or any place within the district that both parties and three witnesses have attended.

6. Declaration of Marriage: Both parties, the three witnesses, and the Marriage Registrar sign a declaration stating that they are not aware of any lawful impediment to the marriage.

7. Registration: After the marriage is solemnized, the Marriage Registrar will enter the marriage certificate in the Marriage Certificate Book, and a marriage certificate is issued to the married couple.

8. Timeframe: The marriage can typically be registered within one to two weeks, depending on the processing time and the availability of appointments at the Marriage Registrar’s office.

9. Documentation: The documents required for court marriage in India include proof of age, residence, passport-sized photographs, and an affidavit stating the parties are not related within the prohibited degrees of relationship.

10. Witnesses: Three witnesses must be present at the time of solemnization, and they need to provide their identification and address proof.
