A will is executed once and read once, and the two moments are usually years apart. Everything in this article happens in between. A validly executed will is not a system that tracks your life; it is a snapshot of one afternoon of it. English law then operates on the snapshot mechanically, as events occur — and none of its mechanisms asks what you would have wanted.
This article summarises a Standard Index Group paper, 'The Stale Will' (SIG-WP-2026-08). The full paper is linked at the end.
Four mechanisms, none of which consults you
Marriage revokes the whole will (Wills Act 1837, section 18). The document you signed simply ceases to exist as an instrument, and most people who marry are never told. Divorce does something stranger: the will survives, but every gift to — and appointment of — the former spouse takes effect as if that spouse had died on the day the marriage ended (section 18A). Selling an asset you specifically gifted deletes the gift, with no compensation from the sale proceeds — the rule is called ademption. And a beneficiary who dies before you deletes their own gift by lapse, subject to a statutory rescue that reaches only your own descendants (section 33).
Each mechanism executes a rule. The leading cases are a catalogue of outcomes nobody in the story intended — including one in which a testator's chosen charity lost its gift because his former wife had failed to die, and the estate went on intestacy instead.
"I have a will" is a true sentence — and it quietly terminates the attention the document still needs.
The sentence that does the damage
The paper's real subject is the mechanism by which a true sentence — I have a will — ends the thinking. The will was made, so the matter is closed; the matter is closed, so nobody looks at the document again; and the family eventually reads a will the testator, in any meaningful sense, never wrote. A will made once and never updated is the most common estate-planning failure in the UK.
Reform will not save it
The Law Commission's 2025 report recommends abolishing revocation by marriage. If enacted, that removes the one mechanism that at least fails towards the formal spouse or civil partner — and leaves the pre-marriage will standing instead. The draft Bill contains a power to save a badly executed will. It contains nothing to save a perfectly executed one that has outlived its facts.
The discipline that follows
The paper sets out the discipline: a short list of trigger events — marriage, divorce, a birth, a death, a sale — a periodic floor for review even when nothing has happened, and a defined inspection when a trigger fires. It is satisfiable with a diary and an ordinary solicitor's appointment. Valoren builds the same discipline into the record itself: the household's events are logged as they happen, and the detection runs continuously — so the will is read against the life it is meant to describe, not rediscovered against it at the worst possible moment.
