Promise?

Court: not proved

It was quite a promise.

According to Darren Hill, it was first made beside a swimming pool during a family holiday in Vietnam.

His parents-in-law, Natalie and Jeremy Berg, had built a successful fabric business. Their daughter Marnie had worked in it since she was 16.

Darren said the Bergs promised that if he joined the business, he and Marnie would eventually inherit it.

He did join. Years passed. The business grew. Then Marnie died. And the alleged family promise became the subject of litigation.

Darren claimed that he was entitled to the shares in the business and also relied upon alleged promises concerning two industrial units from which it operated. The business was reported as being worth approximately £10 million — a reported and claimed valuation rather than a figure determined by the court.

There was just one fundamental problem. Natalie and Jeremy Berg said: we never made the promise.

After trial, the judge agreed with them.

This is the other side of proprietary estoppel. Sometimes the court enforces a family promise. Sometimes the court decides there was never a promise at all.

From market stalls to a multimillion-pound business

Natalie and Jeremy Berg built Fabric Land into a substantial textiles business. Contemporary accounts describe humble beginnings followed by decades of work building the company.

Their daughter Marnie became deeply involved in the business. She joined at approximately 16 and devoted around 30 years of her working life to it.

This was not therefore simply an investment owned by distant parents. It was a family business.

And family businesses create a particular problem: the dividing line between family and business can become extremely difficult to identify.

The holiday in Vietnam

According to Darren’s case, the crucial conversations began during a family holiday in Vietnam in 2004.

The setting was remarkably informal. A swimming pool. A family holiday. A conversation about the future.

Darren alleged that Natalie and Jeremy indicated that he and Marnie would ultimately receive ownership of the family business when the parents retired. He said similar assurances were subsequently repeated.

Those alleged assurances mattered because Darren said they influenced one of the most important decisions of his working life.

2007: Darren joins the business

In April 2007 Darren joined Fabric Land. His case was that he did so because he relied upon the promises made by his parents-in-law.

The Bergs’ account was very different. They said Darren joined because Marnie asked them to give him a job.

That factual difference goes to the heart of proprietary estoppel. Was Darren reorganising his life in reliance upon a promise of future ownership? Or had he simply accepted employment in the family company?

Years later, the court had to decide which version was true.

Marnie

This is also a story shaped by tragedy.

Marnie Berg had spent most of her adult working life in the family business. She died in 2022, aged only 49.

Her death changed the family completely. Whatever expectations may previously have existed about the future of Fabric Land now had to be considered without her.

The dispute which followed was therefore not merely commercial. The claimant was suing the parents of his deceased wife over the future ownership of the business in which she had spent approximately three decades working.

That is precisely the kind of combination of grief, family history, money, memory and expectation which can turn a disagreement into an inheritance war.

The claim

Darren claimed that the assurances entitled him, through the doctrine of proprietary estoppel, to ownership connected with the family business.

His case concerned the shares in Fabric Land and separately alleged promises concerning two industrial units from which the business operated.

Contemporary reports valued the business at approximately £10 million. The Bergs resisted the claim completely and denied making the promises on which Darren relied.

What is proprietary estoppel?

Proprietary estoppel can, in appropriate circumstances, prevent somebody insisting upon their strict legal rights where another person has reasonably relied to their detriment upon an assurance concerning property.

In simplified terms, the court will commonly need to examine four questions.

The doctrine

“But you promised me…”

  1. 1

    Assurance

    Was there a sufficiently clear promise or assurance concerning property?

  2. 2

    Reliance

    Did the claimant rely upon that assurance?

  3. 3

    Detriment

    Did the claimant suffer detriment because of that reliance?

  4. 4

    Unconscionability

    Would it be unconscionable in all the circumstances for the person who gave the assurance to go back on it?

This is a simplified explanation only. Proprietary estoppel is a flexible equitable doctrine and the precise legal analysis depends upon the facts.

The first hurdle

Before you can rely on a promise, you have to prove there was a promise.

That sounds obvious. In family litigation, it frequently isn’t.

Family promises are rarely recorded like commercial contracts. Nobody says: “Before we continue this conversation beside the swimming pool, could you please sign these minutes?”

Instead, years later, courts hear evidence such as:

  • “Dad always said the farm would be mine.”
  • “They told us we would take over the business.”
  • “She said the house would come to me.”
  • “He said I would be looked after.”

The words may have been spoken. They may have meant something entirely different. Or they may never have been spoken at all.

The court rejects Darren’s account

After trial, HHJ Gerald rejected Darren’s evidence concerning the alleged promises.

The claim to the business failed. The separate case based upon alleged promises concerning the industrial units also failed.

The fundamental factual foundation of the proprietary estoppel claim had not been established. The doctrine itself was not found wanting: the assurances on which it depended were simply not proved.

The alleged promise was that the business would ultimately pass to Darren and Marnie. The court found the promise was not proved. The proprietary estoppel claim was dismissed.

The problem with family memory

Twenty years separated the alleged Vietnam conversation from the eventual litigation.

Think about what that requires a court to do. Who was present? What exactly was said? Was it serious? Was it conditional? Was it simply family optimism?

Did the speaker mean “you two are the future of the business”? Or “one day we’ll give you the business”? Those are not necessarily the same thing.

And memories evolve — particularly when subsequent events have transformed the relationships between everyone involved.

The absent witness — again

And once again, one of the most important people was missing: Marnie.

She had spent approximately 30 years in Fabric Land. She was the Bergs’ daughter. She was Darren’s wife. If promises had been made about Darren and Marnie eventually taking over the business, her evidence could plainly have been important.

But Marnie had died in 2022, and the claim was brought after her death. The court had to reconstruct the family’s expectations without the person who stood at the centre of both sides of the family.

This is becoming a recurring theme of Inheritance Wars: the person who could explain the family’s understanding is often the person who can no longer give evidence. The same difficulty runs through Rea v Rea and McDaniel v Talbot.

Family business or future inheritance?

Working in your parents’ — or parents-in-law’s — business creates no automatic right to inherit it.

Nor does working there for many years; being described as “the future”; expecting eventually to run it; or assuming that succession will follow family lines.

But equally, a genuine promise may sometimes have legal consequences where somebody reorganises their life in reliance upon it.

The difficulty lies in distinguishing expectation from assurance.

“But I gave them years of my life”

That is often the emotional heart of proprietary estoppel litigation.

A claimant may say: “I could have worked somewhere else. I could have built my own business. I accepted less money. I stayed because I was told it would eventually be mine.”

The defendant may answer: “You were paid. You had a career. You benefited from working in the family business. We never promised ownership.”

Both narratives can describe the same twenty years. The court has to decide which legal consequences follow from them.

Could mediation have resolved it?

Potentially. But this was a difficult mediation case because the parties disagreed about the fundamental historical fact.

Darren said: you promised us the business. Natalie and Jeremy said: we didn’t.

Darren faced the risk that the court would reject the alleged assurances entirely. The Bergs faced a substantial claim to a valuable family business, a multi-day trial, the uncertainty inherent in witness evidence about conversations decades earlier, costs, public scrutiny and continuing litigation with their deceased daughter’s husband.

The economics of that risk are the same ones we examined in Teixeira v Moaven and in our analysis of why inheritance disputes are rising.

The cost of never writing it down

There is another obvious lesson.

Family-business succession should not depend upon everybody remembering the same conversation twenty years later.

If parents genuinely intend a child or son-in-law to receive the company, shares, business premises or other substantial assets, those intentions should be addressed properly through company arrangements, shareholder agreements, succession planning, wills, trusts or other appropriate professional documentation.

The precise mechanism requires professional advice. But the principle is simple: if a £10 million business depends on a promise, write down the promise.

The lesson from Fabric Land

Not every inheritance expectation is an inheritance right. Not every family assurance is legally enforceable. And not every claimant who has worked for years in a family business can establish proprietary estoppel.

The doctrine can provide powerful relief. Winter demonstrates that. Thorner demonstrates that. But the Fabric Land dispute demonstrates the other side.

The first question remains brutally simple: can you prove the promise?

The swimming pool problem

According to Darren Hill, the future of a multimillion-pound family business was discussed beside a swimming pool in Vietnam. More than twenty years later, a judge had to decide what had been said.

The alleged promise was not proved. The claim failed.

That is an extraordinary inheritance story. But the underlying problem is extremely ordinary.

Families talk informally about the future all the time. “One day this will be yours.” “You’ll take over when I retire.” “Don’t worry, you’ll be looked after.”

Usually nothing goes wrong. Until somebody dies.

Then a sentence remembered by one person as a promise may be remembered by another as nothing more than conversation.

And suddenly, the most expensive words in the family may be the ones nobody wrote down.
