When do cross-border trust and estate disputes arise?

Cross-border trust and estate disputes arise where family wealth, trusts or succession arrangements involve more than one country. This is increasingly common as families live, work and invest internationally, and as wealth is held through offshore or multi-jurisdictional structures.

These disputes often combine technical legal complexity with sensitive family dynamics, requiring careful coordination and early strategic advice.

Cross-border disputes frequently arise where:

  • a trust is governed by offshore or foreign law
  • assets are located in different jurisdictions
  • beneficiaries or trustees live abroad
  • wills have been made in more than one country
  • succession rules differ between jurisdictions

Even where a will or trust appears straightforward, international elements can significantly alter outcomes.

Why are cross-border disputes more complex?

International disputes are more complex as they often involve:

  • competing court jurisdictions
  • conflicting succession regimes
  • forced heirship rules limiting testamentary freedom
  • different standards for trustee duties
  • enforcement challenges across borders

Without a coordinated strategy, disputes can escalate quickly and become disproportionately costly.

 

How are cross-border disputes resolved?

Resolution often requires:

  • determining jurisdiction and applicable law at an early stage
  • working with trusted overseas lawyers and fiduciaries
  • coordinating parallel proceedings where necessary
  • strategic negotiation informed by international risk

We cab provide clarity, structure and control in inherently complex situations.


Which country’s laws apply to a trust or estate dispute?

One of the most important questions in any international trust or estate dispute is which country’s law applies. The answer can determine who inherits, what claims are available, and whether a dispute succeeds at all.

 

Key factors that determine applicable law

The applicable law may depend on:

  • the deceased’s domicile
  • habitual residence
  • nationality
  • the governing law of the trust
  • the location of assets
  • whether forced heirship rules apply
  • whether EU succession rules apply

Different rules may apply to movable and immovable assets, adding further complexity.

 

Why does applicable law matter?

Applicable law can affect:

  • validity of wills and trusts
  • entitlement of beneficiaries
  • availability of Inheritance Act or equivalent claims
  • enforceability of decisions
  • tax exposure

Early identification of the governing law is often decisive in shaping strategy.


How we help

We advise on conflict-of-laws issues at an early stage, helping clients avoid parallel litigation, unnecessary cost and adverse outcomes.


Can trustees be removed in offshore or foreign trusts?

Trustees of offshore or foreign-law trusts may be removed or replaced where governance has broken down, duties have been breached, or confidence has been lost.

The legal test and procedure depend on the governing law of the trust and the jurisdiction involved.

 

When might removal be appropriate?

Applications to remove trustees may arise where there are concerns about:

  • breach of trust or fiduciary duty
  • conflicts of interest
  • failure to act impartially
  • lack of transparency or accountability
  • breakdown of relations with beneficiaries

The court’s focus is typically on the proper administration of the trust, not punishment.

 

Practical considerations in offshore cases

Offshore trustee disputes often involve:

  • parallel proceedings in trust jurisdictions
  • coordination with protectors or fiduciaries
  • interim protective measures
  • asset preservation across borders

We work closely with overseas counsel to ensure a cohesive approach.


How are offshore trust assets traced and recovered?

Where trust assets have been misapplied, concealed or dissipated, tracing and recovery may be required. In international cases, this can be complex but effective with the right strategy.

 

Common asset recovery scenarios

Asset recovery issues may arise where:

  • trustees have acted outside their powers
  • assets have been transferred through corporate structures
  • funds have moved between jurisdictions
  • beneficiaries suspect concealment or misuse

 

How asset recovery works in practice

Recovery may involve:

  • forensic accounting and asset tracing
  • court applications for disclosure
  • interim injunctions or freezing orders
  • coordination with foreign courts

Early action is often essential to preserve recoverability.


Can I contest a foreign will?

It may be possible to contest a foreign will, depending on where the assets are located and which law applies.

When can a foreign will be challenged in the UK?

Challenges may be possible where:

  • UK assets are involved
  • the will was made by a UK-domiciled individual
  • the will does not comply with applicable formalities
  • there are concerns about capacity, influence or fraud

 

Practical considerations

Foreign will disputes often involve:

  • parallel proceedings in different countries
  • translation and expert evidence
  • coordination with overseas lawyers

We manage disputes strategically to control cost and risk.
