In the United States, marital agreements are recognized in the 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.  A marriage is a form of protection for both parties who marry. A marriage pact can protect your funds and assets that you hold before the marriage is concluded. A prenup can also define the amount of debts each person may owe before marrying and make each person responsible for these amounts. In the event of an unhappy divorce, a prenup can be extremely helpful, as it is an agreement on many key issues that should be defined in the context of a divorce. Often, a marital agreement helps relieve tension and conflict in the context of a divorce process. It is often helpful to protect former children if you die without a will. Even in countries that have not adopted UPAA/UPMAA such as New York, properly executed marriage contracts have the same presumption of legality as any other treaty.  It is not necessary for a couple who signs a marriage pact to keep separate lawyers to represent him as long as each party understands the agreement and signs it voluntarily with the intention of being bound by its terms. There is a strong public policy that favours parties that control and decide their own interests through contracts.  There are no state or federal laws requiring adults with contractual capacity to hire a lawyer in order to enter into a marriage contract such as a marriage contract, with the exception of a California law that requires the parties to be represented by a lawyer if spousal assistance (support) is limited by the agreement.
 The marriage agreement may be challenged if it is proven that the contract was signed under duress.  Whether a pre-marriage contract was signed under duress must be justified by the facts and circumstances of this case. For example, it was found that a spouse`s assertion that she believed there would be no marriage if it was not a marriage, where the marriage was only two weeks away and marriage plans had been made, was not sufficient to demonstrate coercion.  As it stands, it is unlikely that a court would maintain a marriage agreement in the United Kingdom if: in a 1990 California case, the Court of Appeal imposed an oral marriage agreement on the estate of one of the parties because the surviving spouse had significantly changed his position based on the oral 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.  For a prenup to be valid, you and your spouse must enter into the agreement without coercion.
