In 2015, the U.S. Supreme Court granted same-sex marriage the same legal basis as same-sex marriage, in the case of Obergefell v. Hodges (decided June 26, 2015). The consequence of the Supreme Court decision is that a pre-marriage contract entered into by a same-sex couple in one state is enforceable in the event of a divorce in another state.  Post-ascendant agreements are similar to marital agreements, except that they are concluded after a couple`s marriage.  When divorce is imminent, post-uptial agreements are called separation agreements.  In California, a couple may waive their property-sharing (co-ownership) rights through a prior contract.  The agreement may limit sp assistance (although a court may set it aside in the event of a divorce if it considers the restriction to be unacceptable). The agreement can be used as a contract to make a will that requires one spouse to take care of the other in the event of death. It may also restrict inheritance law in the event of death, such as the right to inheritance allowance, the right to execution, the right to take as a predetermined heir, etc.  In California, registered national partners may also enter into a prenup. Post-marriage agreements are treated very differently in California law.
Spouses have a fiduciary duty to each other, so pre-marital agreements fall into a particular category of agreements. There is a presumption that the post-parental agreement was obtained by undue influence when a party gains an advantage. Disclosure cannot be abandoned as part of a post-marriage agreement. [Citation required] In India, marital agreements are very rare and have no laws in force. However, in the face of rising divorce rates, there is a growing interest in them. Some legal experts believe that prenups have no legal sanctity in India. However, in some cases, usually among wealthy citizens, a form of contract is signed. But agreements must be reasonable and not violate existing laws, such as the Hindu Marriage Act. Indian courts allow for the signing of a settlement protocol during divorces. But no court has yet been asked to impose a prenup.  Preliminary contracts in Canada are subject to provincial legislation. Every province and territory in Canada recognizes marital agreements.
For example, in Ontario, marriage contracts are called marriage contracts and are recognized by Section 52 of the Family Law Act.  In the United States, marriage contracts are recognized in all 50 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.     In a 2016 survey conducted by the American Academy of Matrimonial Lawyers (AAML), member lawyers reported that the total number of clients seeking premarital marriage arrangements has increased in recent years, particularly with the Millennial generation, with the greatest interest in protecting capital gains in the case of separate ownership, inheritance and shared ownership.  When a U.S. citizen decides to marry an immigrant, that person often serves as a visa sponsor to ask his fiancée to enter or stay in the United States. The Dept. Homeland Security requires that persons who sponsor their fiance come to the United States on a visa to make a declaration of support and it is important to consider the obligation under oath to support a U.S. sponsor about to sign a pre-married agreement. The Asidavit of Support establishes a 10-year contract between the U.S. government and the sponsor, which requires the sponsor to financially support the fiancé on its own resources.
 As expressly stated on Form I-864, divorce does not end the obligations of assistance that the promoter owes to the United States.
