Marriage can change more than a person’s last name or living arrangements. It can also affect how couples own property, manage debt and approach financial decisions. For someone entering marriage with a business, savings or property of their own, these changes may prompt a closer look at how to protect those assets. A prenuptial agreement offers one way to discuss these concerns, but misconceptions about what it can do may make the conversation harder than it needs to be.
Here are three common myths about prenups in California and what the law actually says:
1. Myth: A prenup can control every aspect of married life
A prenuptial agreement does not give one spouse unlimited control over the other. Under California Family Code Section 1612, couples can address property ownership, financial obligations and how they will divide assets if they separate or divorce. They may also include certain other terms that comply with the law.
However, a prenup cannot override every legal protection. For example, couples cannot use one to adversely affect a child’s right to support. The law limits what a prenup can govern, so couples should focus on financial arrangements rather than trying to dictate every aspect of their relationship.
2. Myth: Signing a prenup means expecting divorce
Discussing a prenup does not mean a couple expects their marriage to fail. Instead, the process can encourage honest conversations about debt, income, property and financial expectations before marriage.
These discussions may prove especially helpful when one partner owns a business, has significant assets or expects to receive an inheritance. By addressing financial concerns early, couples can make informed decisions about how they want to manage their resources. A prenup can support financial planning without defining the emotional commitment behind a marriage.
3. Myth: Any signed prenup will hold up in court
Signing a document does not automatically make every provision enforceable. California law requires a written agreement signed by both parties. Courts may also refuse to enforce an agreement if a party did not sign voluntarily or if specific legal requirements were not met.
For agreements signed on or after Jan. 1, 2020, California requires at least seven calendar days between presenting the final agreement and signing it. Independent legal counsel also plays an important role in protecting each party’s interests, particularly when the agreement addresses spousal support.
Ultimately, a prenup’s enforceability depends on the circumstances surrounding its creation and the terms it contains.
Let the conversation start before the wedding
Couples do not have to view financial planning as a prediction of how their marriage will end. A prenup can instead create space to discuss what each person brings into the relationship and what financial responsibilities they are willing to share. Those conversations deserve careful thought, especially when an agreement could affect property or financial security years later.
A California family law attorney can explain the legal options, identify potential concerns and help each partner understand the consequences before signing.
