Today, 21 April 2026, would have been Queen Elizabeth II's 100th birthday. Across the United Kingdom, official centenary events are marking what would have been a remarkable milestone for Britain's longest-reigning monarch, including a royal visit to the new exhibition "Queen Elizabeth II: Her Life in Style" at The King's Gallery, Buckingham Palace, which opened on 10 April and runs until October 2026. Amid the pageantry and nostalgia, however, one aspect of the late Queen's legacy remains entirely private: her will, sealed by court order and not to be opened for 90 years.

For UK estate planning lawyers and financial advisers, the Queen's hidden will is more than a matter of royal mystique. It is a case study in how the wealthiest families in Britain — and indeed any family — plan for the transfer of wealth across generations.

The Sealed Will: Why You Cannot Read It

Queen Elizabeth II's will, like those of previous senior royals, was sealed by the Family Division of the High Court following her death in September 2022. This practice traces back to 1910 and was designed to protect the privacy of the Royal Family and, in the court's own words, to "prevent sensationalism."

The sealing order means the will is locked away for 90 years, after which it will be reviewed by the Keeper of the Royal Archives and the Attorney General. No member of the public — and no journalist — will see its contents in our lifetimes.

This legal protection is not unique to royalty. While ordinary UK wills become public records upon grant of probate, there are legal mechanisms available to private individuals who wish to keep the terms of their estate private. Certain offshore trust structures and discretionary family trusts, when set up properly, can limit how much information enters the public domain. A UK wills and probate solicitor can advise on the options available depending on the size and complexity of an estate.

The Inheritance Tax Exemption: A £500 Million Lesson

Perhaps the most striking aspect of the Queen's estate is the near-total absence of inheritance tax. According to GOV.UK's official inheritance tax guidance, assets passed from one monarch to the next are exempt from inheritance tax under the terms of a "sovereign to sovereign" agreement reached in 1993 between the then Prime Minister and Buckingham Palace.

This means that the Crown's private property — estimated by some analysts to be worth in excess of £500 million in personal assets, including Sandringham and Balmoral — passed to King Charles III free of the 40% inheritance tax charge that would apply to most UK estates above the nil-rate band threshold.

The rationale, as stated at the time of the 1993 deal, was to preserve the financial independence of the monarchy from government. Whether one views this as a sensible constitutional arrangement or an extraordinary privilege, it illustrates a basic principle that applies to all estate planning: structure matters. The same asset, transferred in different legal ways, can carry vastly different tax consequences.

What UK Families Can Learn From This

Most UK residents are not monarchs. But the core principles behind the Queen's estate arrangements — advance planning, clear documentation, tax-efficient structure, and generational thinking — are directly applicable to anyone with assets to pass on.

The nil-rate band and residence nil-rate band. Every individual in England and Wales is currently entitled to a £325,000 nil-rate band, above which inheritance tax is charged at 40%. A married couple can effectively double this to £650,000. The residence nil-rate band — available when a main home is passed to direct descendants — adds a further £175,000 per person, taking a couple's combined threshold to £1 million. Above these thresholds, strategic planning becomes essential.

Gifts and the seven-year rule. Gifts made more than seven years before death are generally free from inheritance tax. A pattern of structured gifting to children or grandchildren — within annual exemption limits of £3,000 per person, or larger gifts that fall outside the estate after seven years — can significantly reduce an estate's taxable value. A wealth management adviser can model the impact of different gifting strategies over a ten or twenty-year horizon.

Trusts. Discretionary trusts, life interest trusts, and bare trusts each offer different mechanisms for transferring assets while retaining elements of control or protection. Unlike a direct bequest in a will, assets held in a properly structured trust may not form part of the taxable estate at all. Legal and financial advice is essential before establishing any trust, as the rules are complex and specific to individual circumstances.

Write a will and update it. This is the most basic requirement — and the most frequently neglected. Approximately 54% of UK adults do not have a will, according to research by Canada Life. Dying intestate in the UK means your estate is distributed according to the Rules of Intestacy, which follow a fixed legal hierarchy and may not reflect your actual wishes. A solicitor specialising in wills and probate can draft a legally valid will and advise on how to update it following major life events such as marriage, divorce, or the birth of children.

Why Her Centenary Is a Prompt for Your Own Planning

Queen Elizabeth II was famous for meticulous preparation — a quality that extended to every aspect of her public and private life. The centenary of her birth is, among other things, an occasion to reflect on what it means to leave a legacy in good order.

For UK families, particularly those with property assets that have increased substantially in value over the past decade, the gap between current estate values and the inheritance tax threshold is narrowing rapidly. Acting early — with proper legal and financial advice — is always more effective than planning under pressure.

Wealth management advisers and wills and probate solicitors are the professionals best placed to guide families through the options. Whether the estate is modest or substantial, the goal is the same: ensuring that what you have built passes to those you intend, as efficiently as the law allows.
