When ultra-wealthy individuals marry, several complex financial and legal considerations come into play. From a technical standpoint, their union can be viewed as a merger of two distinct financial entities, each with its own set of assets, liabilities, and financial obligations.

The before: two individuals with two wealth structures

Swift’s net worth is estimated by Forbes to be USD 1.6 billion, while Kelce’s comes in at USD 70 million. And, with Swift’s track record for smart business moves, and Travis building his own strong brand, it’s assumed that good wealth planning principles have been firmly in place for both throughout their years at work. 

Before marriage, individuals would often have their own wealth structure(s) in place, which will have required thought to be given to various aspects, including:

1. Asset allocation: A diversified portfolio of investments, such as stocks, bonds, real estate, and alternative assets.
2. Estate planning: Arrangements for the distribution of assets upon death, including wills, trusts, and beneficiary designations.
3. Risk management: Measures to mitigate potential risks, such as liability insurance and other forms of risk transfer.

The after: joint, separate – or somewhere in between?

After marriage, a couple needs to consider how to establish and maintain their wealth. This can involve:

1. Pooled income: Combining their incomes to achieve greater financial efficiency and flexibility.
2. Joint asset ownership: Holding assets jointly, such as real estate, investments, or businesses.
3. Shared financial goals: Aligning their financial objectives, including retirement planning, philanthropy, and wealth transfer strategies.

Marital Property Regimes

The way in which assets are owned and managed within a marriage is governed by the applicable marital property regime and can differ from country to country. Common regimes across countries include:

1. Participation in acquisitions: Assets acquired during the marriage are shared equally between spouses, while property such as inheritances or personal gifts remain individually owned.
2. Community of property: Everything owned by the spouses (before or acquired during marriage – depending on the jurisdiction and/or the provisions stipulated in a prenuptial agreement) becomes common property.
3. Separation of property: Assets are held separately, and each spouse retains control over their individual assets. In some cases, this regime may enable an ‘opt in’ for assets accrued during marriage.

It is crucial to inform yourself about the country’s ‘default’ marital property regime.  What are the legal implications of entering a marriage and what are the contractual options? If both parties agree with the terms and conditions: perfect. But if the couple would like to make amendments, a prenuptial agreement can bring clarity.

Prenuptial Agreements

To clarify and protect their individual and joint interests, ultra-wealthy couples may enter into a prenuptial agreement (prenup). A prenup is a contract that outlines the division of assets, spousal support, and other financial matters in the event of divorce or death. While often associated with divorce, prenups can also serve as a useful tool for clarifying the terms of the marriage, including:

1. Wealth structuring: Identifying appropriate asset holding structures for the long-term preservation of wealth, together with the relationship and roles of the parties in regard to them.
2. Inheritance rights: Defining the rights of each spouse to inherit from the other's estate.
3. Spousal support: Establishing the terms of any potential spousal maintenance or support.
4. Business ownership: Determining shareholding structures, directorship of spouses, or buy-sell agreements triggered by divorce or death. 

Prenuptial agreements are not always equally recognised in all jurisdictions, a point that needs to be carefully considered given the global mobility of many signatories to such arrangements.

Post-Nuptial Agreements

While prenuptial agreements are familiar in some shape or form in most countries, post-nuptial agreements (entered after marriage) are not always possible (depending on the jurisdiction). Drafting and signing a post-nuptial agreement can make sense if:

• personal circumstances have changed (e.g. one partner stops working to fully focus on the family).
• significant new wealth is generated during the marriage (e.g., IPO, business sale).
• there’s a desire to update earlier arrangements.

Inheritance implications

Upon the passing of one spouse, the surviving spouse may be entitled to a compulsory portion of the deceased spouse's estate, depending on the applicable laws and the terms of any wills, inheritance contracts, trusts, or beneficiary designations. Ultra-wealthy couples should consider planning their estate to ensure their wishes are met.

Family governance

Family governance frameworks, including family constitutions and advisory councils, can become a useful tool to manage assets and expectations, and to prevent conflict – especially if the family spans generations. It has been known for some wealth creators to burden future generations with mandatory pre-nuptial arrangements in pursuit of wealth preservation or face a dilution of benefits. Ironically, this can often be helpful in mitigating the sensitivity of the topic during courtship. 

Some of the key elements for good family governance include:

• Family protocol or constitution
• Family council and assembly
• Family education programmes
• Family or business succession plans
• Values alignment and creation of a clear family purpose

From Intellectual Property rights to crypto holdings: Intangible Wealth

An often-overlooked facet is intangible wealth. For many, this may mean crypto and blockchain-based assets. For others, it may mean intellectual property – for example, music rights. 

If intangible wealth comes into play, UHNWIs are well advised to create access protocols and include this in their estate planning (digital executors, secure storage).

What does this mean for other UHNWI couples?

UHNW individuals often hold assets across multiple jurisdictions. Marriages that involve international parties introduce significant complexity due to differing national laws on, for example, the following:

• Matrimonial property systems (e.g., community property vs. separation of property).
• Forced heirship rules (common in civil law countries like France, Germany, Italy and Switzerland).
• Recognition of prenuptial agreements (not universally enforceable, e.g., UK historically less binding than US or Switzerland).

It is essential for couples to engage in an open and informed discussion about their goals, values, and expectations, and to ensure that their wealth structures, marital property regimes, estate plans, and more align with their shared vision and objectives. The topic is complex and varies from jurisdiction to jurisdiction. Therefore, it is crucial to involve experts on the planning and implementation.
