Coordinating Prenuptial Agreements Between U.S. and Spanish Legal Systems: A Practical Case

When an international couple decides to get married, one of the most crucial aspects to consider is the division of assets in case of divorce. This becomes especially important when the partners come from different legal systems, such as the Common Law system in the U.S. and the Civil Law system in Spain. The laws can vary greatly between these systems, which can lead to complications if not properly addressed from the start.

The Case of Sara and Michael:

Let’s consider the case of Sara, a Spanish lawyer, and Michael, an American entrepreneur. They plan to marry in Spain but intend to live part-time in both Spain and the U.S., with substantial assets in both countries. To protect their financial interests in the event of a divorce, they decide to sign a prenuptial agreement that clearly outlines how their assets will be divided.

However, a challenge arises when Sara and Michael plan to live in the United States after their marriage. In the U.S., prenuptial agreements are generally enforceable, but the legal system allows judges considerable discretion in altering the terms of property division, especially in divorce cases. In contrast, Spain’s legal system typically respects prenuptial agreements more strictly as long as formal requirements are met (e.g., notarization).

Legal Challenges:

1. Enforceability of Prenuptial Agreements:
   • In the U.S., prenuptial agreements are enforceable but may be subject to judicial modification, especially if a judge finds the agreement unfair. Each state has its own rules regarding prenuptial agreements, with states like California offering more protection to spouses in the division of assets.
   • In Spain, prenuptial agreements (known as capitulaciones matrimoniales) are generally binding once signed in front of a notary. Spain’s Civil Law system tends to be more rigid in enforcing these agreements, unlike Common Law, which allows for more judicial discretion.
2. Choice of Law and Jurisdictional Issues:
   • In the U.S., prenuptial agreements can be governed by the law of the state in which the couple resides. However, this varies by state, and some states (like New York) have specific laws regarding the enforceability of prenuptial agreements.
   • In Spain, if the couple marries there, the Spanish legal system will apply, and they can choose the property regime they prefer (such as separation of assets or community property). However, if they move to the U.S., they may be subject to different rules depending on the state in which they reside.
3. The Solution: Coordinating Both Legal Systems: To avoid conflicts between the U.S. and Spanish legal systems, Sara and Michael should consider drafting two separate prenuptial agreements:
   • One in Spain, that complies with Spanish law and specifies their desired property regime (e.g., separate property or community property).
   • Another in the U.S., ensuring that it complies with state-specific prenuptial agreement laws, which can vary significantly from one state to another.
   Both agreements should include choice of law clauses to ensure that the applicable legal system is clearly defined in the event of a divorce or property dispute.

How to Resolve It:

The best solution would be for Sara and Michael to:

• Sign two prenuptial agreements—one in Spain, in which they select their desired property regime under Spanish law (e.g., separation of assets), and another in the U.S., which complies with state-specific prenuptial agreement laws.
• Include choice of law clauses in both agreements to ensure that they have clearly defined which jurisdiction will apply to their marital property and how it will be divided in case of divorce.

Practical Recommendation:

If you are advising clients in cross-border marriages, it’s essential to emphasize the importance of dual prenuptial agreements in situations where they will live in both the U.S. and Spain. Early legal coordination can help avoid future disputes and ensure that clients’ rights are respected in both jurisdictions.

By preparing two carefully coordinated prenuptial agreements that comply with both U.S. and Spanish law, you can provide your clients with peace of mind, knowing that their financial future is protected, no matter where they live.
