Your family has worked hard to build and preserve wealth over many years, and now your child has just gotten engaged to be married. You don’t want to cause friction with your child’s future spouse, but you’ve seen the statistics and are thinking about broaching the subject of a prenuptial agreement with the couple.

Contrary to popular belief, prenuptial agreements are generally not motivated by a lack of trust or romance. Instead, they are about clarity, fairness, and long-term family stewardship.

Over the years, I’ve seen prenups fail for very predictable and avoidable reasons. Based on that experience, I have developed three simple rules of thumb that may well dramatically improve both family harmony and the enforceability of the agreement itself.

Make Prenups an Early Part of the Family Culture

The most effective prenuptial agreements are never surprises. Conversations about prenups should happen long before a child is seriously dating, engaged, or emotionally invested in a particular relationship. Ideally, these discussions take place while children are still young adults, as part of broader conversations about family values, financial responsibility, stewardship and legacy.

When prenups are introduced early, they are understood as a family norm rather than a reaction to a specific partner. If the first time the topic comes up is after an engagement is announced, the message can easily be misinterpreted: You don’t like this person. You don’t trust this relationship. That framing can damage relationships and create unnecessary and avoidable emotional friction.

By contrast, when children grow up understanding that “this is simply how our family does things,” the conversation becomes neutral. It is no longer personal. It is not about love or distrust of a particular individual; it is about long-term planning. Families that normalize these conversations early remove much of the emotional charge later on.

Encourage Sibling Pacts Around Prenups

One of the most effective strategies I’ve seen is encouraging siblings to make a mutual pact: no matter whom we marry, we will all enter into prenuptial agreements. This approach works remarkably well for several reasons.

First, it reinforces fairness. No one child feels singled out. Everyone is treated exactly the same way. Second, it removes a common narrative that can surface years later, your parents never trusted me. When all siblings follow the same rule, the prenup is no longer perceived as parental interference or judgment about a particular spouse.

A sibling pact also strengthens family unity. It communicates that protecting the family’s financial foundation is a shared responsibility of stewardship, not an individual burden. This collective approach often leads to smoother conversations with future spouses, who can see that the prenup is part of a consistent family framework rather than a personal emotional reaction.

Finish Everything Before Wedding Invitations Go Out

Timing matters enormously when it comes to prenuptial agreements. All negotiations should be completed and the document fully executed well before wedding invitations are sent. Once a wedding is imminent, the risk of legal challenges increases significantly.

Courts scrutinize prenups for signs of pressure, undue influence, or duress. If one party feels that signing is the only way to avoid the embarrassment and financial loss of canceling a wedding, the agreement becomes vulnerable. I have seen situations where prenups were later challenged, and occasionally invalidated, because the timing suggested coercion.

The solution is straightforward: start early and finish early. When both parties have ample time, independent legal counsel, and emotional distance from wedding logistics, the agreement is far more likely to hold up. Just as importantly, the process feels more respectful and balanced to everyone involved.

A Final Thought

Prenuptial agreements are not about planning for failure; they are about planning for clarity. Families that approach prenups early and thoughtfully tend to avoid unnecessary conflict and preserve both relationships and wealth. When handled well, a prenup can be a stabilizing document, one that supports marriages rather than undermines them.

As with so many aspects of family wealth planning, success lies not just in the document itself, but in the conversations that happen long before it is signed.
