Estate Planning for a Globally Mobile World

23rd October 2025

Families who live, work, and invest across borders face a unique challenge. Assets may be held in several countries, while children may hold multiple passports and live in different jurisdictions.

Each location brings its own tax rules, inheritance laws, and reporting requirements. Without a clear plan, these differences can cause delays, disputes, and unnecessary tax exposure.

At Metis, we help globally mobile families design succession and estate plans that create clarity and continuity.

The goal is simple: to protect wealth, preserve family harmony, and ensure a smooth transition between generations.

Why Global Families Need Structured Succession Planning

Traditional estate planning assumes a single home country and one legal system. That approach rarely fits modern international families.

When parents and children live in different countries, they may each fall under a separate set of inheritance or forced-heirship rules. Bank accounts, property, and investments can also be subject to taxation in more than one country.

A coordinated succession plan ensures that:

• Assets pass according to your wishes, not conflicting legal systems.
• Double taxation is minimised through the proper use of treaties.
• Heirs receive what you intend without delay.
• Family values and governance structures continue across generations.

Cross-Border Wills and Jurisdictional Rules

Many families assume a single Will is enough to cover global assets. In reality, Will may not be recognised in other jurisdictions.

Some countries, such as France and Spain, enforce forced-heirship rules that restrict how much you can leave to each beneficiary. Others may require local probate before releasing assets.

A common solution is to hold separate Wills for each country where assets are located. Each Will must work together to avoid conflicts or duplication.

For example, a UK Will can govern UK property and investments, while a UAE Will registered under DIFC rules can cover assets held in the Middle East.

Working with advisers familiar with both UK and local law is essential. At Metis, we coordinate with international legal partners to ensure Wills are compatible and compliant.

Trusts and Foundations

Trusts and foundations remain central tools for international estate planning. They allow families to separate ownership and control, providing flexibility in how wealth is managed and distributed.

Trusts are legal arrangements where assets are held by trustees for beneficiaries.

They can:

• Protect assets from creditors or marital disputes.
• Reduce UK inheritance tax if structured correctly.
• Support minors or vulnerable family members through controlled distributions.

Foundations, commonly used in jurisdictions such as the UAE, Jersey and Guernsey,  are similar but act as separate legal entities. 

Choosing between a trust and a foundation depends on the family’s location, residence status, and long-term goals.

A clear governance document should set out who manages the structure, how decisions are made, and how beneficiaries are added or removed over time.

Family Governance and Next-Generation Preparation

Financial inheritance alone rarely sustains family wealth.

Research shows that many fortunes erode within three generations. The cause is often a lack of shared purpose, communication, and preparation.

Family governance helps prevent this by defining how decisions are made and who is involved.

A simple governance framework might include:

• A family charter outlining values, vision, and responsibilities.
• Regular family meetings to discuss investments, philanthropy, and education.
• Involvement of younger generations in structured financial discussions early on.

Metis facilitates next-generation sessions that combine financial education with open dialogue. This builds understanding and preserves unity, turning inheritance into continuity.

The Role of Life Insurance in Succession Planning

Life insurance can be a powerful funding tool. For international families, it provides liquidity to pay taxes, equalise inheritances, or support dependents without forcing asset sales.

Policies should be written in trust to keep proceeds outside the taxable estate where possible. For globally mobile clients, the policy’s jurisdiction, currency, and regulatory protections also matter. Reviewing cover after major life changes or relocations ensures it remains appropriate.

Coordinating Assets Held in Different Countries

Modern families often hold property, portfolios, and pensions in several jurisdictions. Each may have its own reporting and succession rules.
Key steps include:

1. Mapping every asset – where it is held, its ownership, and its tax exposure.
2. Reviewing account titling – joint ownership may override Will provisions.
3. Maintaining accurate records simplifies probate and reduces delays for executors.

Technology and digital storage solutions can help maintain a secure, central record accessible to trusted professionals when required.

Philanthropy and Legacy

For many international families, legacy extends beyond financial wealth. Charitable donations allow families to support causes aligned with their values.

Creating a structured philanthropic plan offers:

• Tax advantages in certain jurisdictions.
• Inter-generational engagement and shared purpose.
• A positive social impact connected to the family name.

Metis helps families design sustainable giving strategies that complement their wider succession plan.

Key Takeaways

• Review domicile and inheritance tax exposure early.
• Maintain coordinated Wills for each jurisdiction.
• Use trusts or foundations for structure and control.
• Introduce family governance to preserve wealth beyond money.
• Seek professional advice before major relocations or transfers.

Succession and estate planning for global families is about far more than tax. It is about clarity, control, and continuity. With the right structure, you can protect what you have built and ensure it endures – not just for your children, but for generations to come.

This is wealth. Built with Wisdom.
