With respect to financial matters related to divorce, marriage contracts are maintained and enforced on a routine basis by the courts in virtually every state. There are circumstances in which the courts have refused to enforce certain parts/provisions of these agreements. For example, in North Dakota, divorce courts retain jurisdiction to change a limitation on the right to maintenance or assistance from a spouse in a pre-marital agreement if this would result in the spouse who waived that right needing public assistance at the time of the divorce.  Florida and several other states have similar restrictions to prevent an outgoing spouse from becoming a ward of the state after a divorce under a marriage contract.  In addition, the Premarital Agreement Act in Florida, where the share of estate (share of choice) and farm rights granted to surviving spouses under state law are strong enough that a waiver of the surviving spouse`s rights set out in a marriage contract is enforced with the same formality as an enforceable will (notarized and testified by two non-interested parties). Laws differ between states and countries in what content they may be contained and the conditions and circumstances under which a marriage contract may be declared unenforceable, for example. B a contract signed under fraud, coercion or without adequate disclosure of assets. When a U.S. citizen decides to marry an immigrant, that person often serves as a visa sponsor to apply to enter or stay in the United States. The Department of Homeland Security requires that people who sponsor their immigrant fiancé come to the United States on a visa to make an affidavit of support, and it is important to consider the affidavit of support to a U.S.
sponsor about to reject a marriage contract. The affidavit of support creates a ten-year contract between the United States. The government and the sponsor who require the sponsor to financially support the immigrant fiancé from the sponsor`s own resources.  As expressly stated on Form I-864, the divorce does not terminate the U.S. government sponsor`s support obligations and the spouse with an immigrant background has rights as a third party beneficiary of the sponsor`s promise of support in the I-864 affidavit. Therefore, any waiver of alimony must be formulated in their marriage contract in a manner that does not violate the treaty that the United States has. . . .
