These agreements can be covered by the Indian Contract Act 1872. Section 10 of the Indian Contracts Act states that agreements must be considered contracts when they are concluded by the free consent of the parties.  Section 23 of the same statute states that a contract may be non-sour if it is immoral or contrary to public policy.  The marriage contract may be entered into by a woman and a man who have applied for registration of their marriage, as well as by spouses. Minors who wish to enter into a marriage contract before the marriage is registered must obtain consent from their parent or administrator, authenticated by a notary.

At the time of marriage, a marital agreement indicating the ownership regime may be signed between the two parties. If a non-spouse has not been signed, the marital property is simply divided equally between the man and the woman.   Preliminary contracts in Canada are subject to provincial legislation. Every province and territory in Canada recognizes marital agreements. In Ontario, for example, marital agreements are called marriage contracts and are recognized by Section 52 of the Family Law Act.  In some countries, including the United States, Belgium and the Netherlands, the marriage agreement provides not only for what happens in the event of divorce, but also to protect certain assets during marriage, for example in the event of bankruptcy.
Many countries, including Canada, France, Italy and Germany, have marital rules, in addition to or in some cases instead of marriage agreements. Marriage contracts are recognized in Australia by the Family Law Act of 1975 (Commonwealth).  In Australia, a marriage contract is called binding financial agreement (BFA).  In the United States, marital agreements are recognized in the fifty states and the District of Columbia and are enforceable if prepared in accordance with state and state requirements. It has been reported that the demand for marriage contracts in the United States has increased in recent years, especially for millennial couples.
