India has no law on prenuptial or post nuptial agreements. Such agreements are not common in India and are contrary to Indian customs and views about marriage. Nevertheless, the global publicity about celebrity prenuptial agreements is encouraging more affluent people to consider the idea in India.
There appears to be no significant case law in India on the topic of prenups or postnups. Critically, the Supreme Court of India -- which is vested with extremely broad power to do justice between the parties and which has been quite active in matters concerning the grounds for divorce -- has taken no stand on the matter of prenuptial agreements.
It is therefore essential to understand that while prenuptial agreements might be a valuable way for parties in India to express their intention concerning the nature of their financial relationship, it is not possible to assure -- or even to expect -- that such agreed terms will be upheld in an Indian court.
International clients should also anticipate that prenuptial and post nuptial agreements entered into while they reside outside India will likely not be enforced if either of them should initiate a divorce case in an Indian court.
However, Islamic marriages in India are governed by Muslim law. The Muslim Women (Protection of Rights on Divorce) Act provides for the enforcement of sums due under the contract signed by the parties as their marriage contract (mahr).
