Forced Heirship Rules and International Estate Planning: How Global Wealth Is Structured Today

The potential of forced heirship laws to restrict the ability to transfer assets across generations is most significant in the context of international family estates and cross-border estate structures that include multiple countries, offshore property, trusts, etc.

Forced heirship exists in some form within a majority of civil law-based jurisdictions where there are mandatory entitlements from a decedent’s estate to certain beneficiaries (i.e., such as children), which have no relation to a beneficiary’s entitlement by virtue of the terms of a last will and testament.

This presents serious challenges for international families, entrepreneurs, investors, and high-net-worth individuals who own assets in multiple jurisdictions. Therefore, modern international estate planning involves much more than drafting a single last will and testament. Today’s global wealth planning typically includes one or more trusts; an array of offshore holding companies, and multiple jurisdictional wills and/or coordinated succession planning strategies to avoid issues related to forced heirship, taxes, and disputes related to inheritances across borders.

Therefore, it is essential to understand how forced heirship impacts international wealth planning structures as a result of increasing global mobility and growing numbers of people owning cryptocurrencies in order to preserve their long-term wealth in 2026.

Key Takeaways

• Many jurisdictions’ forced heirship laws limit your ability to transfer your estate (regardless of the terms in your will)
• There are many jurisdictions where different factors (residence, ownership, heirs) affect the inheritance law that applies
• The use of trusts and/or other international structures can add some level of predictability and flexibility when dealing with these complex issues
• Where you reside and own your assets greatly impacts how applicable the above-mentioned laws are, and thus their effectiveness
• Digital assets, including cryptocurrencies represent an additional layer of complexity since most digital assets do not fit into traditional inheritance protocols
• Ultimately, designing an appropriate legal framework is far more critical to you than attempting to merely minimize tax

What Are Forced Heirship Laws?

A “forcing heir” refers to an individual who is required by law to inherit a portion of another’s estate. Forced heirs are determined prior to the passing of the owner and are therefore unaffected by any will created by the owner. These types of laws govern civil law countries. Civil law countries provide for the strict regulation of inheritance. Common law systems allow owners much greater latitude with regard to determining how property is passed at the time of the owner’s death.

The purpose of forcing heir laws is to protect immediate family members. Therefore, when creating a will, it may be necessary to include provisions related to forcing heirs.

Who qualifies as forced heirs?

In most jurisdictions where these rules apply, forced heirs are typically:

• Children, who are usually the primary protected beneficiaries
• A spouse, depending on the country and marital regime
• In some cases, parents or financially dependent relatives

How Forced Heirship Is Treated Across Legal Systems

Forced heirship rules primarily exist within civil law jurisdictions, where inheritance rights are governed by statutory succession frameworks rather than broad testamentary freedom.

In many countries, inheritance laws reserve a mandatory share of the estate for protected heirs such as children or spouses, regardless of the terms of a will.

Common law jurisdictions, including the United Kingdom and many U.S. states, generally provide individuals with greater flexibility regarding estate distribution, although certain family protection claims may still apply.

In cross-border estates, determining which succession law applies may depend on:

• Domicile,
• Tax residency,
• Nationality,
• Location of assets,
• And governing succession regulations.

Within the European Union, international inheritance disputes may also involve the EU Succession Regulation (Brussels IV), which helps determine applicable succession law across participating member states.

Countries where forced heirship commonly applies:

In general, the use of forced heir laws is more prevalent in jurisdictions that regulate inheritance through statute rather than case law. Jurisdictions that commonly utilize forcing heir laws include:

• France
• Italy
• Spain
• Brazil and much of Latin America
• The UAE (depending on the structure and which legal framework applies)
• Saudi Arabia and other jurisdictions influenced by Sharia inheritance principles

On the other hand, countries like the UK and the US take a different approach under common law. In those systems, inheritance is generally much more flexible. As long as a will is valid, individuals usually have far more freedom to decide how their estate is divided, without fixed legal shares being imposed in the same way.

Why Forced Heirship Creates Problems in Cross-Border Estate Planning

The issue typically arises when there is a conflict of laws from multiple systems being applied simultaneously.

It’s extremely common that an individual lives in one jurisdiction and holds property in another jurisdiction, or has family/heirs spread throughout several jurisdictions. Typically, each jurisdiction will apply its own succession rules to the individual’s estate. These rules do not always correlate to each other. That is when the friction occurs.

Some examples of key areas of potential friction include:

• Multiple jurisdictions applying their respective succession rules to the same estate;
• There is no alignment on domicile (where an individual is deemed to be) versus location of assets (where the assets are physically located);
• An offshore structure/account creates an additional layer of legal interpretation and/or complexity.
• Property located within countries that enforce strict forced heirship rules overrides an individual’s wishes as to how they would like their estate distributed after death;
• Cryptocurrency assets exist outside of standard estate planning/inheritance frameworks.

Impact on estate structure

Cross-border estates are rarely governed by a single legal system, which is where planning becomes critical.

How Cross-Border Estate Planning Works

The first step in cross-border estate planning is not simply drafting a will for every jurisdiction. The typical approach is much more complex — developing an appropriate framework that can accommodate two or more legal regimes simultaneously.

To this end, families typically do not utilize a single document. Rather, they develop a strategy that will serve them well in all jurisdictions (i.e., based upon residence, location of assets, etc.) by utilizing multiple documents/strategies that address these issues appropriately.

There are several strategies used to facilitate this process, including:

1. Developing wills in two or more countries with laws governing the disposition of assets;
2. Creating trusts to govern who shall receive which assets after death;
3. Creating offshore entities (e.g., corporations) to hold assets when appropriate from both a legal and operational perspective;
4. Creating insurance-based products as a component of comprehensive wealth management plans;
5. Coordinating documents and structures so that there is no conflict among documents and/or structures utilized across borders;

At this point, estate planning ceases to become merely paperwork and evolves to focus on the overall coordination and integration of all aspects of estate planning. This represents creating a type of “legal system” that operates effectively in conjunction with various legal regimes across borders.

Role of Trusts and Offshore Structures

Assets located throughout various countries create a web of complexities and potential issues. At this time, trusts and other offshore entities are created to organize asset ownership and inheritance in a more structured manner.

For instance, a trust does not own assets in one’s name. A trust instead establishes an independent separation of legal title (ownership) and control. In addition, a trust also outlines who will receive the assets upon termination. This allows for a degree of predictability in creating plans related to cross-border estates, particularly when working with multiple legal systems.

Popular options include:

• Nevis Trusts
• Cook Islands Trusts
• BVI Holding Companies
• Jersey & Guernsey Trusts

International estate planning professionals choose these arrangements because they provide greater flexibility with regard to assets and family members residing in multiple jurisdictions.

However, many individuals fail to recognize that none of these options will supersede or override forced heirship laws. Therefore, all of them need to be established and designed in accordance with the applicable local laws and taxes.

Cross-Border Estate Planning with Digital Assets

The use of digital assets has presented entirely new levels of complexity to the field of inheritance planning. The key difference between digital assets and other forms of property — including real estate, financial accounts, etc. — is that many individuals store their cryptocurrency using self-managed “private” keys that do not automatically integrate with the traditional legal system for estate management.

There are also several common issues that appear time and again:

• Private keys may not always reflect the individual’s actual legal ownership interest
• There is currently no unified or global method for dealing with the transfer of digital assets upon an individual’s passing
• Cryptocurrency is classified by governments and regulatory bodies across the world in different ways — sometimes not at all
• Without specific plans, these assets may be lost forever after an individual passes away

Due to the complications associated with digital assets and how difficult it is to determine which assets are truly accessible, many people are now treating crypto as part of their overall estate planning process. They are not allowing themselves to view digital assets as a standalone asset. Rather, they are bringing them into a more formalized structure.

Common structuring approaches:

In terms of how individuals decide to create structures for their digital assets, there is not necessarily a right way to do so. However, based on how much control and separation individuals wish to put into a structure, there seem to be some recurring trends. While there does not seem to be a singular correct way to structure digital assets, some popular methods include:

• Holding bitcoin and/or other cryptocurrencies through an offshore Limited Liability Company (“LLC”)
• Placing Ethereum and/or broader token portfolios under a trust-based structure
• Using trusts instead of legal entities to manage/hold digital assets
• Utilizing multi-signature wallets to provide shared-access and minimize potential risk in regards to “single-point-of-failure” in estate planning

It appears that what is fundamentally changing in the context of estate planning is the type of thinking individuals are employing. In addition to creating a will and/or establishing a document, individuals are beginning to consider the structural needs of their digital assets and ensuring that those assets will remain accessible once an individual has passed.

Legal Tools Used to Navigate Forced Heirship

When dealing with international asset management, most times a family can’t find an “ideal” solution. Most families have to put together their own combination of structures and then make sure they all work together as a cohesive whole instead of trying to rely on one structure that does it all.

Here’s how the main ones are typically used:

Each has its’ own function; a will is used in most cases for domestic issues, while trusts or LLCs are designed to manage how property is maintained. More often than not, well thought out plans include some type of combination of at least two types of structures (as opposed to just using one) to provide each part of the plan with the proper level of structure.

Important Legal and Tax Considerations

Any international estate planning structure will need to be compliant with all the applicable tax, reporting, and inheritance laws for each jurisdiction that has a relevant interest in your estate.

Although offshore trusts, corporations, and holding entities do not automatically provide relief from forced heirship rules, tax residence obligations, and/or disclosure requirements, it is common for courts to scrutinize such structures on the basis of:

• The individual’s place of residence (domicile);
• Their tax residency;
• Beneficial ownership;
• Source(s) of their assets;
• Practical control exercised by them regarding the operation of the entity.

Since there are often significant variations in how inheritance rights are defined and protected across various countries, it is also advisable to work with both experienced legal counsel and tax advisors who have extensive experience in addressing international issues concerning succession.

Common Mistakes in Cross-Border Estate Planning

The most common mistakes people make when trying to create a good cross-border estate plan arise from making assumptions about how different systems work based on laws in one area, which may be true in that legal system but could not possibly fit into another system.

Below are some of the trends we see over and over again from individuals who attempt to create a good cross-border estate plan:

• Relying upon a single will and believing it will apply no matter what country or location you happen to be in.
• Ignoring the possibility of being subject to forced heirship provisions if you own property outside of the United States;
• Not reviewing/updating your domicile/residency due to changes in your life circumstances;
• Owning assets and failing to establish an organizational structure for their development/operation;
• Failing to distinguish between personal property ownership and entity-based property ownership;
• Omitting digital assets (such as cryptocurrency) from your overall plan

Jurisdiction Matters: Where Forced Heirship Applies

Jurisdictions matter because the laws of inheritance vary based on where you own assets and where you are considered to be legally connected. Rules regarding how an estate is treated are not universal. Depending upon the applicable legal system, the way an estate will be handled can change significantly.

Civil law jurisdictions

In general, civil law jurisdictions will have more formal and inflexible approaches to handling estates. Generally speaking, civil law jurisdictions reserve a certain percentage of an estate for those who are considered immediate family. This means that there may be little to no ability to modify this provision. In civil law systems, family rights are given precedence when dealing with estates. Therefore, individual preference does not necessarily play as large of a role in determining how an estate will be handled.

Common law jurisdictions

On the other hand, common law systems generally provide individuals with more options regarding how their assets will be allocated at the time of death. In jurisdictions such as the United Kingdom and the United States, wills and trusts are typically the primary tools utilized by individuals to determine how their estate will be distributed upon their passing. Thus, in many ways, estate planning in these types of systems provides greater control to the individual regarding the distribution of his/her/their estate.

Offshore jurisdictions

The use of offshore banking is sometimes made as part of larger international planning efforts due to the potential for increased structural flexibility. However, it should be noted that an individual’s obligations in terms of taxation and/or domicile will remain tied to the country in which he/she/they are tax resident. As such, merely holding assets offshore does not eliminate the possibility of having the laws governing forced heirship apply to them.

How Families Structure Global Wealth in Practice

Practically speaking, cross-border estate planning doesn’t usually happen in a single step, but rather it develops over time, typically as individuals relocate internationally, obtain additional foreign-based property/asset(s), or become more financially “internationalized”.

The common process generally follows these steps:

1. Tax residency (or domicile) is either confirmed or clarified because that will be the basis for all subsequent work.
2. A global inventory of assets is created across multiple jurisdictions to see exactly which assets sit in each country.
3. Trusts or holding structures are then set up wherever necessary.
4. The will from one or more foreign countries are coordinated so that they do not conflict with each other.
5. Finally, the whole plan is maintained and updated by ongoing reporting and compliance activities.

At its core, this is not simply an exercise to add unnecessary complexity. Rather, it’s to ensure that even if a number of differing legal systems need to apply, the entire strategy remains intact rather than disintegrating at the point of inheritance.

Conclusion

The concept of forced heirship generally pertains to legal systems rather than financial; however, it may significantly affect how your assets are distributed. In addition to potentially creating problems for your heirs in terms of asset distribution when your assets have been located in multiple countries, a traditional will is usually insufficient to protect you from potential issues. One key factor to consider when distributing your assets is the proper formation and utilization of trusts, entities and other documents so they may be used in conjunction with each other to maximize your ability to distribute your assets across multiple countries.
