Should prenuptial agreements include a sunset clause?

On Behalf of | Mar 10, 2025 | Firm News |

A prenuptial agreement (also called a pre-nuptial agreement, prenup, or an antenuptial agreement) is an agreement between a couple who intend to get married to each other that sets forth what will happen in the marriage in the future. Usually a prenup sets forth what will happen in the event the couple get divorced. A well written prenuptial agreement will also explain what will happen if one person dies while married. Prenups may also have an agreement about how the parties are to deal with each other during the marriage even if divorce is not contemplated. There could be provisions about finances, how to argue with each other, how to interact with each partner’s family, or a myriad of other topics.

Some people think that a prenup has the most use and benefits in the early years of a marriage and the benefits decrease as the length of the marriage increases. The parties may feel that the terms of the prenup won’t apply after decades of marriage.

A sunset clause sets an expiration date or certain conditions under which the prenup becomes invalid. Usually it expires after 20 or 30 years of marriage. There are potential pros and cons for using a sunset clause.

Benefits
Evolving Relationship: It acknowledges that relationships grow over time, and financial dynamics may change significantly.
Encourages Commitment: Couples might view the clause as a testament to their mutual trust and long-term intentions.
Flexibility: If financial equality or other circumstances shift over the years, the prenup won’t feel overly restrictive. A sunset clause encourages negotiations between the parties concerning thier relationship which can result in a Postnuptial agreement. They could also agree to extend the prenup without any changes.

Risks
Uncertainty: The clause could create ambiguity about future financial arrangements.
Unintentional Pressure: Some partners might feel pressured to stay in a relationship to avoid financial repercussions after the clause takes effect.
Renewal Complexity: If the clause triggers renegotiation, the process could become emotionally or financially taxing.

Ultimately, whether to include a sunset clause depends on the unique dynamics of the couple and their shared goals. Some find it adds a layer of fairness and adaptability, while others prefer the stability of an open-ended prenup or no prenuptial agreement at all.
