Inheritance Wars: “That’s for My Death Duties” — The Farmer Who Promised a Farm Without Ever Quite Saying So
Thorner v Major — nearly 30 years of unpaid work, a famously taciturn farmer, an oblique promise and the question of whether a farm had really been promised at all

Proprietary estoppel succeeds
Some inheritance disputes begin with a will.
This one began with a piece of paper.
In 1990, Somerset farmer Peter Thorner handed his relative David Thorner a Prudential insurance bonus notice relating to life assurance policies. Peter said:
“That’s for my death duties.”
That was more or less it.
He did not say “I promise to leave you my farm.” He did not sign an agreement. He did not make a will leaving David Steart Farm.
But David understood what Peter meant. For years he had worked on Peter’s farm, and he would continue to do so for many more years, largely without pay. And David believed that one day Steart Farm would be his.
Peter died in 2005. He left no will. The farm therefore became the subject of one of the leading modern cases on proprietary estoppel.
The family
Peter Thorner and David Thorner were related through the farming family: Peter was a first cousin of David’s father. Peter had no children. He had been married twice. His first wife, Sarah, had owned Steart Farm, and Peter inherited it from her after her death in 1976.
David was considerably younger and had grown up in the same Somerset farming world. From the 1970s onwards he increasingly helped Peter with farm work, livestock, machinery, management and the everyday running of Steart Farm.
This was not an ordinary employer-employee relationship.
The two men
This is important to understanding the case. Peter was a man of very few words.
The House of Lords repeatedly emphasised the context of the relationship. Peter was not someone who spoke clearly and formally about his intentions. He tended to communicate indirectly. David understood him. That mattered enormously.
What sounds vague to a stranger may be perfectly clear between two people who have known each other for decades.
David’s work
David began helping substantially at Steart Farm during the 1970s and 1980s, and his involvement increased. The judge found that David provided very considerable unpaid assistance. He did not simply appear occasionally to lend a hand. Peter expected David to assist him, and David increasingly organised his own life around the farm.
By the late 1980s, David had begun to believe that his future lay at Steart Farm.
“That’s for my death duties”
In 1990 Peter handed David a Prudential bonus notice relating to life assurance policies and said: “That’s for my death duties.”
The trial judge found that this was the watershed moment. Peter intended David to understand that he would succeed to Steart Farm when Peter died. David did understand it that way. It strengthened his expectation that the farm would eventually be his.
This was not the only indication over the years. Peter subsequently made other remarks and behaved in ways which reinforced David’s expectation. But there was never a conventional written promise.
What Peter never said: “I hereby promise that Steart Farm will pass to you when I die.”
What Peter actually said: “That’s for my death duties.”
That sentence did its work only because of everything around it: the context, nearly thirty years of work, other remarks, a shared understanding — and, from that, an expectation of the farm.
Why didn’t David just ask?
This is one of the most human aspects of the case. The answer was essentially: that wasn’t their relationship.
The two men were not commercial negotiators. They were relatives working together on a farm. Peter communicated obliquely. David did not demand a written contract or repeatedly ask, “Can you confirm that I will inherit?”
In a family context, that may seem entirely unsurprising. Legally, however, it created a formidable problem after Peter died.
Peter never made the will
The extraordinary feature is that Peter apparently continued to intend David to have the farm. The House of Lords noted that there was no suggestion Peter ever changed his mind. As late as 2002, Peter was still behaving in a way consistent with David eventually succeeding him.
But intention is not the same as an effective testamentary disposition. Peter died in 2005, aged 77. And he died intestate.
He appears to have intended David to have the farm. He just never made the will that would have achieved it.
The legal problem
Without a will, the statutory intestacy rules applied. David could not simply say, “Everyone knew Peter wanted me to have it.” An intention to make a gift in the future does not ordinarily transfer property.
So David relied upon proprietary estoppel.
Was there even a promise?
That was the central difficulty. Peter had never made the sort of clear statement familiar from other cases — “the farm will be yours”. His communications were oblique.
The court therefore had to decide whether his words and conduct nevertheless amounted to an assurance sufficiently clear to support proprietary estoppel.
The trial
The deputy judge, Mr John Randall QC, heard the evidence. He found David to be “painfully honest”.
The judge concluded that Peter had intended David to understand that he would inherit Steart Farm, that David reasonably understood Peter that way, and that David had relied upon the assurance. David therefore succeeded.
The remedy was substantial. He was entitled to Peter’s farming business assets, including the farm property falling within the order, livestock, machinery and related assets, subject to the terms of the order and an inheritance-tax indemnity. This was not simply “David gets all 560 acres”: the farming unit included tenanted land and the order was more nuanced.
Court of Appeal: not clear enough
Peter’s personal representatives appealed, and the Court of Appeal reversed the trial judge. The difficulty centred upon whether Peter’s oblique words and conduct were sufficiently definite, and whether the assurance was intended to be relied upon.
In other words: could “that’s for my death duties” really amount to a promise of a farm?

Trial → Court of Appeal → House of Lords
- 1
Trial before Mr John Randall QC, sitting as a deputy judge — David wins
- 2
Court of Appeal — the assurance is held insufficiently clear; David loses
- 3
House of Lords, 25 March 2009 — the trial judge’s decision is unanimously restored; David wins
Three court levels to decide what a taciturn farmer had meant.
The House of Lords
The House of Lords unanimously restored David’s victory. The speeches are now a leading modern authority on proprietary estoppel. The critical point was context.
One of the central lessons from the case is therefore that clarity depends upon context. A statement may be insufficiently clear in one relationship but perfectly intelligible in another.
What about the fact that the farm changed?
Another issue was uncertainty about exactly what “Steart Farm” meant. The size and composition of the farming operation changed over the years: land was bought, land was sold, some was rented and some was let out.
The House of Lords nevertheless concluded that the subject matter was sufficiently identifiable in context. The relevant assurance was effectively about whatever constituted Steart Farm when Peter died.
The result
The House of Lords restored the trial judge’s decision and David’s proprietary-estoppel claim succeeded. After decades of unpaid work and years of uncertainty, he received the farming property and business interests covered by the order.
The simplest lesson in the series
Peter apparently wanted David to inherit. David believed he would inherit. Peter repeatedly reinforced that understanding. David arranged decades of his life around the farm. Peter never appears to have changed his mind.
Yet because Peter did not implement that intention properly, the question went to trial, then to the Court of Appeal, then to the House of Lords.
Whatever the eventual value of the assets, Peter could have eliminated most of the uncertainty by taking appropriate professional advice, making an effective will, and reviewing it when necessary — the practical steps set out in How Not to Start an Inheritance War: 10 Things You Can Do Before You Die.
If you want someone to inherit your farm: put it in your will.
Do not rely upon hints, nods, insurance documents, family assumptions, or sentences which only make sense because somebody has known you for thirty years.
Two farm promises — two very different stories
Thorner v Major. The assurance was oblique. The owner died intestate. The claimant worked for decades in expectation. Proprietary estoppel succeeded.
Winter v Winter. Repeated family assurances that sons would ultimately share the farming business and property. A later will departed from the expected arrangement. Proprietary estoppel succeeded.
These cases demonstrate how informal family succession planning can eventually become formal litigation.
And sometimes the court doesn’t believe the promise existed
In the Fabric Land family dispute, the alleged assurance concerning a multimillion-pound family business was not established.
That produces the crucial distinction. Thorner: promise proved. Fabric Land: promise not proved.
Before the court can enforce the promise, someone has to prove there was a promise.
“One day…”
Families frequently say: “One day this will all be yours.” “You’ll have the farm.” “You’ll take over the business.” “You’ll always have somewhere to live.” “We’ll see you right.” “You’re the one carrying this on.”
Sometimes these are expressions of hope. Sometimes they are statements of present intention. Sometimes they are real assurances intended to be relied upon. After death, the court may have to decide which.
The dead person cannot explain
Peter could no longer explain what he meant, whether he intended David to rely on it, whether circumstances might have changed his mind, or exactly what he regarded as “the farm”.
The court therefore had to reconstruct the relationship from witnesses, words spoken years earlier, conduct, documents, and the history of two men working together.
The problem with a family promise is that the person who made it may be dead when the court has to decide what it meant.
The pathway
How succession by hint becomes litigation
- 1
Assumption
One generation assumes everybody already knows who will take the farm.
- 2
Years of work
The next generation organises a working life around that assumption.
- 3
Expectation
Remarks and conduct steadily reinforce the belief that the farm will pass.
- 4
No will
The intention is never converted into an effective testamentary disposition.
- 5
Death
The one person who could explain what was meant is no longer available.
- 6
Litigation
The court must reconstruct the promise from witnesses, conduct and documents.
Expectation is not estate planning.
A classic mediation case
Could mediation have resolved it? Potentially, yes. This was exactly the kind of dispute in which both sides faced profound uncertainty.
David could say: “I worked for decades because I was promised the farm.” The estate could say: “Where is the promise?”
The legal uncertainty was demonstrated perfectly by the litigation history: David won. Then lost. Then won again. That is litigation risk in its purest form.
A mediator could have asked:
- How strong is the evidence of the assurance?
- What does “that’s for my death duties” really prove?
- How will the trial judge assess David’s evidence?
- How much detriment did David actually suffer?
- What is the value of the farming assets?
- What happens if the estate wins?
- What happens if David wins?
- What will appeals cost?
- Can David retain the core farm while other beneficiaries receive other assets?
- Can land or cash be divided?
- Can a structured settlement preserve the farming business?
Don’t plan succession by hint
Family farms and businesses are particularly vulnerable to these disputes. One generation may assume: “Of course David knows it will be his.” The next generation may assume: “Of course Dad will put it in the will.”
Nobody has the difficult conversation. Nobody documents anything. Decades pass. Then someone dies.
Expectation is not estate planning.
The farmer who never quite said it
Peter Thorner was not a man who used many words. That was part of who he was. David understood him. The trial judge understood their relationship. Ultimately, the House of Lords concluded that the law could understand it too.
The words “that’s for my death duties” were not a formal promise. Standing alone, they tell us very little. But in the context of decades of unpaid work, a close farming relationship, other remarks and conduct, and a shared understanding about David’s future, they were part of an assurance which equity would enforce.
David eventually inherited the farm. But only after litigation which reached the highest court in the country. There was a much simpler way: Peter could have made a will.
If your inheritance plan requires a future judge to understand your hints, it is not much of an inheritance plan.

Cases referred to & sources
The price of the war
The published judgment does not provide a reliable final figure for the total cost of the litigation.
What could a mediated settlement have looked like?
These are examples of settlement structures which mediation could have explored. They are not outcomes which actually occurred, and the legal, tax and practical consequences of any settlement require appropriate professional advice.
Division of the land
Particular fields or parcels could have been allocated between the claimant and those entitled on intestacy.
Transfer of the farmhouse with a payment
The working farm and the house could have been dealt with separately, with an equalising payment.
Deferred sale
A sale could have been postponed to allow the farm to continue trading.
Inheritance Wars
Four questions
- What did the court have to decide?
- Whether oblique assurances over many years amounted to a promise sufficient to found a proprietary estoppel claim to the farm.
- What did the parties risk?
- The farm itself, nearly 30 years of unpaid work and appellate costs through to the House of Lords.
- What could mediation have done differently?
- Mediation could have divided the land and structured a buyout rather than requiring a court to interpret a taciturn farmer’s remarks.
- What should families and advisers learn?
- Farming families should record succession arrangements; oral assurances place everything on the recollection of survivors.
Inheritance Wars
Real cases. Real families. Real consequences.
The court can decide who is right. Mediation asks whether there is another way.
