Imagine this: you have worked on the family farm since you were a teenager. Long hours, little or no pay, and years of hard work, all because you were told, “One day, this will all be yours.”
But when the time comes, that promise is broken. Perhaps your parents change their will. Perhaps a sibling steps in and claims ownership. Suddenly, you are left with nothing.
This situation is sadly common in farming families. It is also where the legal principle of proprietary estoppel can help.
What is proprietary estoppel?
Proprietary estoppel is a legal doctrine that protects people who have relied on a promise about land or property. It often applies where someone has worked or cared for family property based on an assurance that they will inherit it later.
To make a successful proprietary estoppel claim, you need to show three things:
- A clear promise or assurance – for example, “You will get the farm when I am gone.”
- Reliance on that promise – such as staying on the farm, working for low pay, or turning down other opportunities.
- A resulting loss or detriment – like giving up a career, financial independence, or a home because you trusted that promise.
If these elements are proven, the court can enforce the promise, even if it was never written down.
Why farming families are affected
Farming families are particularly prone to these disputes. Promises are often made informally, sometimes decades earlier, and family relationships or wills can change over time.
It is not unusual for someone who has dedicated their life to keeping the farm running to be left out of the estate entirely.
Here are two well-known examples:
- Guest v Guest (2022, Supreme Court) – A son worked on the family farm for more than 30 years after being told he would inherit it. When his parents changed their will, the court ordered them to pay him significant compensation.
- Habberfield v Habberfield (2019) – A daughter worked long hours on the family farm, giving up her own life and career. The court awarded her over £1 million to recognise the broken promise.
At Acuity Law, we regularly act for individuals in similar situations where hard work, loyalty, and trust have been taken for granted.
What the court can do
If your proprietary estoppel claim succeeds, the court has the power to provide a fair remedy. This could include:
- Transferring part or all of the promised property
- Awarding financial compensation
- Placing the property in trust for your benefit
- Making another order that reflects what was promised and what is fair now
Each case is assessed on its own facts. The court’s focus is always on achieving fairness and preventing injustice.
Do you have a potential proprietary estoppel claim?
If you have been promised land or property, particularly within a farming family, and have relied on that promise to your detriment, you may have a strong claim.
You do not need a written agreement, but acting quickly is important. The sooner you seek advice, the better your chance of protecting your position before property is sold or transferred.
