MODIFICATION OF CIRCUMSTANCES AND RELATED PROPERTY The parties acknowledge that their respective property may increase, decrease or remain the same during the marriage and expressly and irrevocably declare that no change in the financial situation of either party may affect this contract. For a marriage contract to be enforceable in court, it must meet five basic procedural requirements: a marriage contract or “prenup” is a written contract concluded before a couple marries – most often when they are engaged. This agreement defines the financial and property rights of each spouse when the marriage ends in separation, including death or divorce. 4. Children: If one or both parties have children from a previous relationship, they may indicate this in this section. This part of the agreement allows the parties to dictate whether they plan to provide children from a previous relationship with adequate shelter and support, without creating an obligation to continue this assistance in the event of the end of the marriage. . . .
