The courts will not require a person to do all the housework or to have the children raised in a particular religion.  In recent years, some couples have included social media provisions in their marriage contracts and have set rules on what can be posted on social media during the marriage, and in case the marriage is dissolved.  Even in states that have not adopted UPAA/UPMAA such as New York, properly executed marriage contracts are admitted to the same presumption of legality as any other contract.  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.  A sunset scheme may be included in a marriage agreement stipulating that the contract expires after a certain period of time. In Maine, it automatically expires after the birth of a child, provided the parties do not renew the contract if the parties do not renew the agreement.  In other countries, a number of years of marriage will result in the expiration of a marriage. In countries that have adopted the Uniform Premarital Agreement Act (UPAA), there is no sunset provision in the law, but one could be under private contract.
Note that the states have different versions of the UPAA. 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.
