The world of international estate, trust and tax planning is evolving rapidly.  Decades of globalisation combined with unprecedented mobility of the world’s wealthy has made it common to have clients whose residences and assets range across multiple jurisdictions. This can lead to planning challenges during life and at death, as families are often affected by multiple, and often conflicting, tax laws, rules of inheritance, treaties and cultural norms. As a result, international private client lawyers must work closely with legal advisers in many jurisdictions to ensure that advice is not being given in isolation, and that all factors affecting a client’s planning have been identified. 

Understanding and appreciating the cultures of the various jurisdictions (both legal and national cultures) is also vital, and lawyers who do so will be increasingly valuable, whether in non-contentious planning or in trust and estate litigation. An effort to bridge cultures and languages will also make mistakes much less likely. Lawyers who function as a team, who respect the intricacies and unique aspects of each legal system, and who recognise that an appreciation of language and culture is fundamental to successful cross-border work, will have enormous advantages over lawyers who see multi-jurisdictional planning or litigation as separate pieces where each lawyer has responsibility only for his or her jurisdiction. The Chambers Private Wealth Global Practice Guide is designed to help encourage and facilitate this cross-border co-operation.

A few of the recent global trends in the law that relate to families, their businesses and their planning are discussed below.

The Demand for Increased Transparency

The most dramatic force of change in the international private client world is of course the global drive for transparency. Governments are increasingly focused on cross-border arrangements and structures and have implemented regulatory schemes that require the exchange of tax-related information.  For example, the United States overcame initial resistance to obtain near-complete international compliance with the Foreign Account Tax Compliance Act (“FATCA”). 

The Common Reporting Standard (“CRS”), the reciprocal automatic information exchange agreement developed by the Organisation for Economic Co-operation and Development (“OECD”) has recently been adopted in over 100 jurisdictions, and is being phased into effect from 2016 through to 2018. CRS requires entities (including trusts and foundations) to report information on “controlling persons.” For entities, the controlling persons generally are the individuals who exercise control over the entity or who have a direct or indirect controlling ownership interest in the entity. For a trust, the controlling persons are defined to include the settlors, the trustees, the protectors (if any), the beneficiaries or class of beneficiaries, and any other natural persons exercising ultimate effective control over the trust (whether directly or indirectly). Of course, few of these individuals (who may be resident in numerous jurisdictions) actually “control” a trust, yet the broad reporting requirements will create significant compliance burdens and challenges for trustees and financial institutions dealing with trusts. The global reach of CRS will also make co-operation of teams of advisers across multiple relevant jurisdictions that much more important.

Much has been written about the fact that the United States is not a party to CRS and commentators have suggested that the United States has become an attractive jurisdiction for non-US persons wishing to maintain their privacy. 

In addition to an increased emphasis on the automatic exchange of information in programmes that purport to make the information available only to tax and law enforcement authorities, some governments and organisations have pressed for even greater transparency, demanding public registers. In 2014, the European Parliament, for example, proposed a public register for trusts held in the European Union that would require disclosure of the name, date of birth and nationality of the trustees, settlor, protector and any beneficiary or class of beneficiaries. If enacted, these and similar regulations would have serious implications for clients who wish to keep their affairs private from the general public.

The United Kingdom has already enacted similar legislation in the context of shareholders of corporations, which requires disclosure of persons with significant control. Since 6 April 2016, all UK-incorporated companies and LLPs are required to maintain and hold open for public inspection a register of natural persons with “significant control”. 

The substantial reporting burdens of these types of regulations have already had a notable impact on the offshore trust world. Many smaller trust companies simply do not have the resources to comply with the complex regulations, and the risks of incorrect reporting often outweigh the benefits of taking on clients from certain jurisdictions. 

Scrutiny of Tax Planning 

Individuals have faced increased scrutiny over the use of various tax planning vehicles. An increasingly intense debate has emerged regarding the “morality” of these structures which, though perfectly legal, are thought by some to be morally incorrect. The recent “Panama Papers” hacking in April 2016 has fuelled this debate. 

The focus on tax reporting mechanisms is global. For example, Russia has recently passed new anti-avoidance and anti-offshore legislation. Under these rules, Russian resident individuals are taxed on the undistributed profits of foreign structures if the resident individual is considered a controlling person of such a structure. Many countries in Latin America have enacted “Controlled Foreign Corporation” legislation and taxation. More and more countries, such as the United Kingdom and India, have enacted general anti-avoidance rules, which empower the revenue authorities to deny taxpayers the benefit of arrangements that are structured solely to avoid taxes and have no other commercial substance or purpose. 

In this context, it is not surprising that the so-called “revenue rule,” which was described in Attorney General v Lutwydge, an eighteenth century English case, and generally allows courts to decline enforcement of foreign tax judgments or application of foreign revenue laws, has been eroded. A dramatic example of this is Pasquantino et al v United States, 544 U.S. 349 (2005), in which the United States Supreme Court held that the evasion of foreign taxes may be prosecuted under US criminal laws that prohibit the use of interstate wires in furtherance of a scheme to defraud.

Another important example is a recent decision of the Court of Appeal of Guernsey, which has provided guidance on the limits of a trustee’s duty to keep the affairs of a trust confidential when faced with a possible criminal tax prosecution from another jurisdiction. In Re B, Guernsey Judgment 35/2012 (Court of Appeal, 11 July 2012), trust beneficiaries opposed the disclosure by a trustee of confidential information in response to a summons issued by a French investigating magistrate. The Guernsey Court found that if the information were not disclosed, there would be a real and imminent risk to the trustee (the French investigating magistrate proposed to issue an arrest warrant against the trustee’s legal representative for failing to provide information), and permitted the trustee to disclose the information sought.

Rise of Estate and Trust Litigation

The world is in the middle of the greatest generational transfer of wealth in history and the world of cross-border estate and trust litigation has never been busier. Trustees find themselves entangled in a rising number of complex and costly cross-border disputes, often serving as the target of aggrieved beneficiaries (or excluded family members) from, for example, jurisdictions that have forced inheritance laws and that often do not recognise trusts. 

Whether representing fiduciaries or challengers, anticipating litigation can go far towards increasing the likelihood of obtaining a favourable result (whether through the courts or negotiated settlement). The greatest risks in multi-jurisdiction trust litigation come from the potential clash of laws and procedures of the different countries, yet these inconsistencies also create opportunities for surprise and victory. The litigation team that truly understands the intricacies in each jurisdiction and appreciates the contrasting cultural forces can exploit the gaps that are created to their substantive and procedural advantage. 

The Future

All of these trends and forces – transparency, scrutiny of tax planning, the increase in trust and estate litigation – will continue and will receive the most publicity. But of course the world of private client advice does not involve only these areas. Much of our work relates to helping families structure the succession of wealth in responsible and lasting ways, preserving long-existing family businesses, encouraging family harmony, and protecting family assets for both current and future generations. These needs will also continue and grow. 

New challenges that are emerging include, for example, adapting current laws and structures to evolving methods of reproduction due to scientific and medical advancements. These range from the increasing use of surrogacy arrangements, to the birth of children from frozen embryos after one or both of their biological parents are dead, and even to posthumous conception and reproduction. Laws to address issues of inheritance rights and the definition of “issue” and “legitimate” in these contexts either do not exist or conflict among jurisdictions.
