Currently, 28 states and the District of Columbia have adopted an updated version of the Uniform Premarital Agreement Act (UPAA) or the Advance Agreements Act (UPMAA). The UPAA was adopted in 1983 by the Uniform Law Commission (ULC) to promote greater uniformity and predictability between state laws with respect to these contracts in an increasingly temporary society. The UPAA was partially enacted to ensure that an effective prenup in one state is awarded by the courts of another state where the couple could obtain a divorce. UpMAA was created in 2012 by the ULC to clarify and modernize the inconsistent laws of the state and create a uniform approach for all marital agreements and post-marriage agreements that: marriage contracts have always been a controversial topic for couples. Media portrayals of marital agreements show them as devices used by celebrities and other similar wealthy individuals to limit the amount of wealth an ex-spouse can claim. Making a couple talk about divorce when they get married can be a tough sell to someone who has planned a wedding. For couples who enter into a partnership with comparable assets, a marriage pact. aka prenup, is rarely controversial. In practice, projects can violate canon law in many ways.
For example, they cannot subject a marriage to a condition of the future. The code of canon law provides that “a marriage on a condition for the future cannot be concluded with validity.” (CIC 1102) Some federal laws apply to conditions that may be included in a pre-marital 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. Each state has rules for prenupes, but the American Bar Association notes that “all mandates that such agreements are procedural and material “fair”. Determining whether an agreement is fair requires knowledge of the fundamental principles of contract law, such as capacity, coercion, fraud and inappropriate influence. 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.  Premarital agreements are civil, so Catholic canon law does not exclude them in principle (z.B to determine the distribution of property between children of a previous marriage after the death of a spouse).
Premarital mediation is another way to create a conjugal arrangement. In this process, a mediator facilitates an open discussion between the couple on all kinds of marriage issues, such as expectations regarding post-birth work and savings and spending styles, as well as traditional pre-marital discussions on real estate sharing and spousal assistance when the marriage is over. The engaged couple makes all decisions about what would happen in the event of separation or divorce with the help of the mediator. They then design either a memorandum of agreement or a pre-marital agreement and have them checked by their respective lawyers. An agreement that is developed on mediation is usually cheaper because fewer hours are spent with lawyers, because the couple made all the decisions together rather than a page against.
