Which of the following cannot legally be included in a prenuptial agreement?

In the context of prenuptial agreements, child support agreements cannot be legally included because these provisions are subject to state guidelines and the best interests of the child. Courts typically retain the authority to determine child support in a way that reflects the specific needs of the child and the parents' financial situations at the time of the divorce or separation.

While parents can agree on various financial matters in a prenuptial agreement, such as how to divide property or who is responsible for debts acquired during the marriage, agreements concerning child custody and support must ultimately pass judicial scrutiny. This ensures that the child's welfare remains the primary concern, preventing parents from contracting away their legal obligations to provide support. The state's interest in protecting the well-being of children overrides personal agreements between parents, making child support provisions unenforceable in prenuptial agreements.
