In the past, in England and Wales, marital agreements had not been considered legally applicable in England and Wales for public policy reasons. The parties have the option of entering into a pre-marital contract before the breakdown of the marriage. If they follow the rules, the agreement will likely be a valid and enforceable document. There have been long legal disputes when one party challenges the validity of the prenup. A few years ago, the first wife of a well-known baseball player filed for divorce. She sought sole custody of her two children, her Florida villa, her Mercedes and a court order invalidating her prenup. This would mean that the court would then proceed with a fair distribution of their matrimonial property under Florida law. In Judaism, the Ketubah, a marriage contract, has long been established as an integral part of Jewish marriage and is signed and read at the wedding. It contains the man`s requirement to support his wife by providing her with food, clothing and sexual intercourse and provides for the wife`s support in the event of divorce or death of her husband. Under this passage, however, a woman can walk if her husband does not take care of her. A prenup may provide more support to a child than state law requires, but it cannot offer less. Neither party can waive the right to custody of children under the law of the state in which it seeks divorce.
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.  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 remain 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.
