In India unlike in western countries, marriage is considered as a religious alliance of a man and a woman for life and thus a prenuptial agreement is legally not valid under the Hindu Marriage Act, 1955 in India, however it is governed under the Indian Contract Act, 1872. Under the Muslim Laws and to an extent in Christian Laws, marriage is considered to be a contract between the marrying couple, and with that contract comes certain automatic property rights for each spouse. However, in case of divorce or separation both the spouses, struggle with the hearings of their case in court, pinning the blame on the opposite party, all so that the person may get to pay less amount of money as alimony and it is here that the importance of a prenuptial agreement comes into play.
It is basically an agreement in writing between two spouses which states that in the event of death or divorce or separation what will be the monetary liability of the respective spouses. In simple words it lays out the proportion of property, assets and money each of them will get if the marriage is dissolved.
