The Marie Potter lost house dispute has attracted attention because what began as a disagreement between neighbours over a shared driveway eventually developed into a major legal and financial dispute. The case involved damages, legal costs, a charging order against a home and, ultimately, eviction. In March 2026, the High Court considered the legal issues around enforcing the earlier order in McGowan v Potter [2026] EWHC 595 (Ch).
The story reminds us that neighbour disputes can become far more serious once court proceedings begin. It also illustrates how an unpaid civil judgment can eventually become connected to property ownership and enforcement.
Who Is Marie Potter?
Marie Bernadette Potter was the defendant in a series of proceedings arising from a dispute involving a shared driveway at a property in Shirley, Croydon. According to the High Court judgment, the original proceedings resulted in an order dated 26 August 2020 requiring Potter to pay Kirsten McGowan £30,452.95 in damages and a further £27,000 in costs.
The dispute was not originally about the loss of a home. It grew out of a disagreement between neighbours concerning access to and use of a shared driveway. The subsequent court proceedings turned what may have seemed like a local property dispute into a substantial financial liability.
How Did the Marie Potter House Dispute Begin?
At the heart of the conflict was a shared driveway and disagreement over access. Reports about the case describe the relationship between Potter and her neighbour deteriorating after complaints about parking and access to a garage. The dispute became significant enough to reach the courts rather than being resolved between the homeowners.
The keyword phrase “mum persists in parking on neighbour’s driveway despite complaints” reflects the type of neighbour-conflict scenario that can attract public attention: repeated parking or access disagreements can create frustration when one household believes another is obstructing a driveway or interfering with established rights. The Potter case demonstrates how quickly such disputes can become more complicated once allegations, claims and court orders enter the picture.
From Parking Disagreement to Legal Claim
The original legal proceedings eventually produced a judgment against Potter. The High Court later recorded that she did not pay the damages and costs awarded in 2020. As interest accrued and additional costs were incurred, the total amount owed increased.
This development was critical because the dispute was no longer simply about where a vehicle was parked. It had become a question of how a court judgment could be enforced.
What Happened to Potter’s Home?
On 30 December 2020, the County Court Money Claims Centre made a final charging order for £69,351.07 against Potter’s property at Bennetts Avenue in Shirley. A charging order can secure a judgment debt against property, linking the unpaid sum to the debtor’s interest in that property.
The charging order was followed by an application for an order for sale. The claimant issued the relevant proceedings in May 2021, and a hearing took place in December of that year. On 29 December 2021, an order was made providing for the property to be sold unless Potter paid a specified amount by the deadline.
The original order stated that the property was to be sold for no less than £575,000, although that minimum price was later reduced. It also required Potter to provide vacant possession.
How Did the Dispute Lead to Eviction?
The order for sale became especially consequential because Potter did not comply with its requirements. The High Court judgment states that a warrant for possession was enforced on 26 April 2023, resulting in her eviction from the property. At the time of the 2026 High Court proceedings, the property had still not been sold and the amount due had not been paid.
This is the central reason the case is often described as a home being “lost” over a neighbour dispute. The court proceedings did not simply impose a fine or require a change in parking arrangements. The enforcement process ultimately resulted in Potter being removed from her home.
Why Did Marie Potter Challenge the Order?
Potter later challenged the validity of the order for sale. Her argument included the contention that the County Court had acted beyond its jurisdiction when making parts of the order. She also brought a counterclaim raising allegations concerning the claimant’s conduct after possession had been obtained.
The High Court proceedings therefore focused on a technical but important legal question: whether the County Court had the necessary jurisdiction to enforce the charging order through a sale of the property.
The issue was particularly significant because different statutory provisions appeared to contain different monetary limits. The judge was required to consider the relationship between the County Courts Act 1984 and provisions of the Law of Property Act 1925.
What Did the High Court Decide in 2026?
On 16 March 2026, the High Court handed down judgment in McGowan v Potter [2026] EWHC 595 (Ch). The court concluded that the County Court had jurisdiction to enforce a charging order by sale where the amount owing was within its equity jurisdiction, which the judgment identified as £350,000.
The judge therefore held that the order for sale made in Potter’s case was valid. The judgment also explained that, even if the order had been made outside the relevant jurisdiction, it would not simply have been something a party could ignore. A court order generally remains binding unless and until it is set aside.
That conclusion was important because it rejected the core argument that the earlier order was invalid merely because of the jurisdictional issue Potter raised.
Why Is the Case Important?
The case has wider significance beyond the particular disagreement between these two neighbours. The High Court itself described the proceedings as a cautionary example of the financial consequences of neighbour disputes for people who do not have extensive financial resources.
One important lesson is that the financial consequences of litigation can become much larger than the original dispute. A disagreement over parking, access or a shared driveway may seem relatively small at first, but once a claim is brought, the losing party may face damages, legal costs, interest and enforcement expenses.
A second lesson concerns property. A charging order can turn an unpaid judgment into a debt secured against real estate. Where the debt remains unpaid, enforcement can potentially lead to an order for sale, subject to the applicable legal requirements.
Key Lessons From the Marie Potter Dispute
Neighbour Disputes Can Escalate Quickly
Arguments about parking and driveway access can become deeply personal, particularly when each side believes the other is ignoring complaints or established rights. Early communication and appropriate dispute-resolution methods can sometimes prevent the issue from reaching court.
Court Costs Can Change the Stakes
The 2020 judgment against Potter included both damages and costs. Because those sums were not paid, the financial burden continued to grow.
Court Orders Should Not Be Ignored
The 2026 judgment placed particular importance on the binding nature of court orders. A party who believes an order is wrong generally needs to challenge it through the proper legal process rather than simply deciding that it can be disregarded.
Property Enforcement Can Have Serious Consequences
The Potter case shows how a civil dispute can eventually affect someone’s home. The progression from judgment, to charging order, to order for sale and finally possession illustrates why property-related litigation should be treated seriously from the beginning.

Conclusion
The marie potter lost house dispute is a striking example of how a neighbourhood disagreement can develop into a lengthy and expensive legal battle. What began with a shared-driveway conflict eventually resulted in damages, substantial costs, a charging order, an order for sale and eviction.
The March 2026 High Court ruling did not simply revisit the original parking disagreement. Instead, it addressed the legal mechanics surrounding enforcement and confirmed that the County Court had jurisdiction to enforce the charging order through a sale of the property.
For homeowners involved in property or neighbour disputes, the broader lesson is clear: once litigation begins, the financial and legal consequences can extend far beyond the original disagreement.
