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.  Some federal statutes apply to conditions that may be contained in a pre-marriage contract. The Withdrawal Equity Act (REA) of 1984, signed on August 23, 1984 by President Ronald Reagan, reconciled confusion over whether ERISA anticipated state divorce laws, thereby preventing pension plans from complying with court injunctions granting a spouse a portion of the worker`s pension in a divorce decree.  A matrimonial agreement may include exceptions whererightly agrees to revoke all rights against the other`s pension benefits arising from state and federal marriage laws, as in the context of the REA. In a 1990 California case, the Court of Appeal imposed an oral marriage in the estate of one of the parties because the surviving spouse had significantly changed his position according to the verbal agreement.  However, as a result of amendments to the act, it has become much more difficult to change the character of community or distinct property without written agreement.  There are two types of marriage contracts that a couple can consent to: when a U.S. citizen decides to marry an immigrant, that person often serves as a visa sponsor to ask their fiance 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.
