In today’s increasingly globalised world, high-net-worth individuals often hold a diverse portfolio of assets dispersed across various jurisdictions. This reality presents a pivotal yet frequently overlooked question in estate planning: should one opt for a singular, overarching Will to govern all global assets, or should one prepare multiple, jurisdiction-specific Wills?
This decision transcends mere legal formalities—it lies at the very core of strategic legacy planning, tax optimisation, and ensuring a seamless transfer of wealth to future generations.
In this month’s Family Legacy Planning article, we explore the nuanced considerations of both approaches, comparing their legal implications and practical consequences for you and your heirs.
The Argument for a Single Will: Centralisation and Convenience
The appeal of a consolidated, all-encompassing Will is understandable. It offers clarity, unity, and streamlined control. From a maintenance standpoint, a single Will simplifies updates and revisions. Amendments need only be made once, with the intent of having it simply apply universally to all included jurisdictions. Moreover, centralising one’s testamentary intentions reduces the administrative burden of tracking multiple documents, mitigating the risk of lost or misplaced Wills across different countries.
However, the simplicity of a single Will often proves illusory. One of the most significant pitfalls lies in the probate process. Most legal systems require submission of the original Will to initiate the probate process. Consequently, if assets span several jurisdictions, probate must be conducted sequentially rather than concurrently, as courts in each jurisdiction may wish to review the original Will before releasing assets. This logistical bottleneck can delay access to overseas holdings by months—sometimes years—especially where notarisation, translation, or local court approval is required.
More critically, a Will that is legally valid in one country may not be recognised in another if it fails to comply with the latter’s legal formalities. Arguably, such risks—ranging from issues of non-recognition to procedural incompatibility—could be mitigated by engaging qualified legal counsel in each jurisdiction to collaboratively vet and tailor the contents of a single, “universal” Will. In theory, a carefully harmonised document could be constructed to comply with the formal and substantive legal requirements of all relevant countries. However, doing so inherently undermines the very simplicity that a global Will purports to offer.
The process of crafting such a Will is often laborious and fraught with complexity. Each jurisdiction has its own statutory and common law requirements concerning execution formalities, forced heirship provisions, tax implications, probate procedures, and conflict of law rules. Coordinating these diverse elements into one cohesive document necessitates an unusually high level of legal precision and inter-jurisdictional collaboration.
Furthermore, the administrative effort required does not end once the Will is signed. Any amendment—no matter how minor—would potentially require a renewed round of legal review across all jurisdictions involved to ensure that the revised provisions do not inadvertently violate local laws or create inconsistencies that could jeopardise probate proceedings. As such, what begins as an attempt at simplicity can quickly evolve into an unwieldy and expensive endeavour, with ongoing maintenance challenges that rival, if not exceed, those associated with maintaining multiple jurisdiction-specific Wills.
The Case for Multiple Wills: Local Compliance and Procedural Efficiency
To address these challenges, many practitioners advocate for the use of separate Wills tailored to each jurisdiction in which assets are held—particularly where real property, businesses, or substantial financial investments are involved.
The benefits are compelling. Most notably, multiple Wills allow probate proceedings to occur independently and concurrently in each country, expediting the administration of the estate. Locally drafted Wills also ensure compliance with jurisdiction-specific requirements, whether these pertain to inheritance taxes, forced heirship rules, or execution formalities such as notarisation or witnessing protocols.
Consider the case of a Singaporean domiciliary with a chalet in Switzerland, a rental flat in London, and a vineyard in Tuscany. Employing locally compliant Wills for each jurisdiction enables the executor to engage directly with local legal professionals and authorities, avoiding procedural entanglements and unnecessary delays. In jurisdictions where the principle of lex situs applies—such as with immovable property—the necessity for local legal instruments becomes not merely prudent, but essential.
Nonetheless, this multi-Will approach is not without its complications. Chief among them is the risk of inadvertent revocation. If one Will includes boilerplate language such as “I hereby revoke all previous Wills,” it could unintentionally nullify the others. Therefore, each Will must be precisely drafted to cover only the assets within its jurisdiction and should explicitly state that it does not revoke any existing Wills executed elsewhere.
Strategic Considerations: Choosing the Right Approach
There is no universally correct solution. The optimal strategy depends on several factors, including the location and complexity of your assets, your domicile and habitual residence, and your family dynamics.
If your overseas assets are minimal and uncomplicated, a carefully drafted global Will that is compliant with private international law and executed in your home jurisdiction may suffice. However, for individuals with significant or immovable assets across several jurisdictions, the use of multiple Wills is often more prudent. In such cases, the delays and complications associated with a single Will could significantly disrupt estate administration.
Singapore’s Stance: A Common Law Framework with Global Implications
Singapore’s legal system, grounded in common law, permits a Will to encompass worldwide assets. However, such flexibility is not a panacea. A Will probated in Singapore may face hurdles in enforcement in jurisdictions like Indonesia or China, where differing legal systems and procedural requirements apply.
Consequently, Singapore practitioners often recommend a hybrid model: a principal Singapore Will covering domestic and residual global assets, accompanied by auxiliary Wills governing specific foreign assets. This approach balances administrative efficiency with legal clarity and compliance.
