A prenup may not contain any questions of child care or child care. The court has the final say in calculating custody of the children. The court determines custody of the children on the basis of a « Best Interest of the Child » standard, which is involved in several factors. A court would never maintain a provision of a marital agreement on derinemonto, child care or visitation, as these are matters of public policy. The court retains the power to decide what is in the best interests of the child and does not deny a child the right to financial assistance or the opportunity to have a relationship with a healthy parent. Recently, a movement has developed in some modern Orthodox circles to support an additional marital agreement. This is a reaction to a growing number of cases where the husband refuses to grant a religious divorce. In such cases, local authorities are not in a position to intervene, both for the sake of separation of church and state and because some halachic problems would arise. This situation leaves the woman in a state of aginut where she cannot remarry. To remedy this situation, the movement promotes a marital agreement in which the couple agrees to file their divorce, should it occur, before a rabbinical court. While no one wants to think about a divorce before they even get married, marital agreements (or pre-marital agreements) must set certain conditions in the event that the marriage ends. For example, a person with an established family business may attempt to protect those assets from the other party in the event of a divorce. However, there are some restrictions on what can be included in a conjugal agreement.
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.
