The BBC Story That Should Terrify Every Trustee: How £50,000 Became 30 Months inPrison

A recent BBC News story stopped me in my tracks. Two sisters, Gemma and Jessica Thomas, watched their mother Katherine Hill receive a 30-month prison sentence for stealing their £50,000 inheritance. But here’s what struck me most: this wasn’t a criminal mastermind. This was a mother who simply didn’t understand her legal responsibilities as a trustee.

And it could happen to anyone.

The Tragedy of Good Intentions Gone Wrong

Katherine Hill wasn’t appointed as trustee because she was financially sophisticated. Like most trustees, she inherited the role when her mother Margaret died in 2014. The £50,000 was placed in a trust fund with Katherine as trustee—money that was meant for her daughters when they reached 25.

What happened next is a textbook example of everything that can go wrong when trustees don’t understand their legal duties.

Katherine put the money in an instant access Barclays Everyday Saver account and gave both herself and her father debit cards to access it. Within a year, they had drained the entire account through ten withdrawals, with £35,000 disappearing in just three transactions.

When her daughter Gemma later asked about accessing the money early to buy the family home, Katherine’s response was devastating: “the money’s not yours.” She then blocked her daughter’s number and later claimed in court that the money had been “posted through the girls’ letterboxes.”

The Legal Reality Every Trustee Must Understand

What Katherine Hill apparently didn’t realise is that being a trustee isn’t just a title—it’s a serious legal responsibility. As a trustee, you are:

Legally responsible for trust assets: The money belongs to the beneficiaries, not to you. You cannot treat it as your own, even temporarily.

Required to act in the beneficiaries’ best interests: Every decision must prioritise their welfare and financial security.

Obligated to keep proper records: You must be able to account for every penny and every decision.

Duty-bound to comply with legal and tax obligations: Trusts have specific legal requirements that cannot be ignored.

Required to seek professional advice when necessary: If you don’t understand something, you have a legal duty to get help.

Katherine Hill breached every single one of these duties. The court described her actions as “greedy and spiteful,” but I suspect the reality was simpler: she didn’t understand that accepting the role of trustee meant accepting serious legal obligations.

The Warning Signs Were All There

In hindsight, the sisters could see why it would happen through signs of their mother’s financial behaviour:

• Building an expensive back garden pub and hot tub

• Taking frequent holidays

• General extravagance that seemed inconsistent with her income

But they didn’t know to question it because they were young and Katherine had also received her own inheritance from her mum.

The tragic irony? She was spending their money while they struggled financially. Jessica, now a nurse, still lives with her boyfriend’s parents because saving for their own home without the inheritance “would take a very long time.”

The Real Cost: Far More Than Money

The financial theft was devastating, but the emotional cost has been even higher. As Jessica told the BBC:

“I’ll never have a relationship with my mother now... How can you grieve something you never had? But she’s robbed me of an opportunity not a lot of people get.”

Both sisters have needed counselling. Jessica developed a tic that doctors attributed to trauma and struggles with “massive issues with trust.” Gemma became “very needy in friendships” and questioned: “if my mother doesn’t love me, who the hell is going to love me?”

The family has been destroyed. Ten years of legal proceedings. A mother in prison. Children who will never trust again.

All because someone didn’t understand their legal duties as a trustee.

How This Could Have Been Prevented

Here’s the part that keeps me awake at night: this tragedy was completely preventable.

If Katherine Hill had sought professional advice when she first became trustee, she would have learned:

Proper account setup: Trust money must be kept completely separate from personal finances. No shared access cards. Clear naming conventions. Detailed record-keeping.

Legal obligations: Understanding that trustee duties are not optional or negotiable. The beneficiaries’ interests come first, always.

Investment responsibilities: An instant access savings account may not be the most appropriate investment for money that won’t be needed for years.

Documentation requirements: Keeping detailed records of all decisions and transactions.

When to seek help: Recognising situations that require professional guidance.

The cost of proper trustee education? A few hundred pounds at most. The cost of getting it wrong? £65,000 (with inflation), 30 months in prison, and a destroyed family.

The Questions Every New Trustee Must Ask

If you’ve been appointed as a trustee, ask yourself:

• Do I fully understand my legal duties and potential personal liability?

• Have I set up proper systems to keep trust finances completely separate?

• Do I know what records I need to keep and for how long?

• Do I understand the tax implications of the trust?

• Do I know when and how to seek professional advice?

• Have I considered whether the current investments are appropriate?

If you answered “no” or “I’m not sure” to any of these questions, you need professional help.

The Professional Responsibility

As someone who works with trustees regularly, I see the fear in people’s eyes when they realise the scope of their responsibilities. Many trustees are family members who never expected or wanted this role—they inherited it through circumstances, not choice.

That’s exactly why professional guidance is so crucial. You don’t become a trustee because you’re a financial expert. You become a trustee because someone trusted you to do right by their loved ones.

But good intentions aren’t enough. You need to understand the law, maintain proper systems, and recognise when you’re out of your depth.

The Vulnerable Beneficiary Complexity

This case becomes even more concerning when we consider trusts with a vulnerable beneficiary. These trusts often involve more complexity. The potential for disaster multiplies exponentially.

When beneficiaries have disabilities or mental health conditions, the trustee’s duty of care is likely to be even greater. The stakes are higher because the beneficiaries may be less able to detect problems or advocate for themselves.

A System That Fails Families

Perhaps the most tragic aspect of the Thomas family story is how avoidable it was. We have a legal system that routinely appoints family members as trustees without ensuring they understand their responsibilities.

Imagine if we appointed people as company directors without explaining their legal duties. Or made them executors without explaining probate law. Yet we do exactly this with trustees, then act surprised when things go wrong.

Moving Forward

The Thomas sisters’ story should be a wake-up call for anyone involved in trust management. Whether you’re:

• A solicitor setting up trusts: Are you adequately educating trustees about their ongoing responsibilities?

• A family member appointed as trustee: Do you fully understand what you’ve agreed to?

• Someone considering trust arrangements: Are you choosing trustees based on their ability to fulfil legal duties, not just family relationships?

The sisters found some closure when their mother was convicted. As Gemma said: “it was like we were being told that we’re not crazy.” But the damage to their family is permanent.

The Bottom Line

Katherine Hill didn’t set out to destroy her relationship with her daughters or spend time in prison. She made a series of decisions that seemed reasonable to her at the time, not understanding that each one was a serious breach of legal duty.

The £50,000 trust fund was meant to provide security and opportunity for Gemma and Jessica. Instead, it became the instrument of their family’s destruction.

Professional trustee education isn’t a luxury—it’s an essential safeguard for families. The cost is minimal compared to the potential consequences of getting it wrong.

If you’re a trustee, get help. If you’re setting up a trust, ensure your trustees understand their responsibilities. If you’re a professional advising families, make trustee education a priority.

Because somewhere today, another well-intentioned family member is making the same mistakes Katherine Hill made. And without proper guidance, they’re heading for the same devastating outcome.
