Millionaire half sisters face off in ‘obsessive’ court row over dad’s £2.7m New Forest mansion

Millionaire half-sisters Lindsay Bisiker and Judith Bisiker are embroiled in a high-stakes legal battle over the ownership of a £2.7 million New Forest mansion, known as Moonhills. The dispute, described as "obsessive" by media outlets, centers around whether the property was ever meant to be held in trust for the entire Bisiker family or if Judith, who holds the legal title, has the unilateral right to sell it. The case has drawn significant attention due to the emotional and financial stakes involved, with both women presenting starkly contrasting narratives about the intentions of their late father, Jim Bisiker, who passed away in 2023. The conflict began when Judith, 63, announced her intent to sell Moonhills, a six-bedroom estate with stables, a tennis court, and four acres of land located near Beaulieu. Purchased by their father in 1984, the property was initially registered solely under Judith’s name. Despite this, Lindsay, 50, argues that the house was always intended to serve as a family asset, accessible to all members. She claims that the property functioned as her primary residence in the UK while she attended boarding school and during holidays, and that it played a crucial role in her upbringing. Lindsay further asserts that her father consistently expressed a desire for the house to remain within the family, ideally purchased by one of his children to ensure its continued use. The tension escalated dramatically in April 2023 when Judith allegedly evicted Lindsay without notice. According to Lindsay, she was staying at Moonhills with her dogs when Judith changed the locks, effectively barring her from the property. This action, Lindsay claims, was motivated by Judith’s belief that Lindsay was interfering with the sale process. She now seeks a ruling from the High Court that Moonhills is held on trust for the family, allowing her to acquire the property at a reduced price and maintain it as a family home. Additionally, she is seeking compensation for what she describes as an unlawful eviction. Judith, however, maintains that she is the sole legal and beneficial owner of the property. Her legal team contends that any informal arrangements regarding family use were not legally binding and that Jim Bisiker’s later statements, particularly those made in his final years, lack reliability due to his declining mental health. They argue that Judith’s decision to sell the property was entirely within her rights and that the changes to the locks were necessary to protect the sale from interference. The case has attracted considerable public interest, with both sides presenting compelling arguments rooted in familial history and emotional ties. Lindsay’s legal representatives emphasize that Jim Bisiker, a former Royal Marine turned oil tycoon, consistently supported Lindsay’s position. They cite written documents from 2016 to 2023 and a witness statement affirming that Moonhills was meant to be a shared family resource. Barrister James Sandham highlighted that the property was treated as a communal space, with the children allowed free access and maintenance funded by Jim. He argued that Judith’s actions—excluding Lindsay and attempting to sell the property—constituted a breach of trust and a violation of Jim’s wishes. In contrast, Judith’s counsel, led by barrister James Saunders, challenged these assertions. They pointed out that Jim’s early life included periods spent abroad and that his later years were marked by cognitive decline. Saunders emphasized that Judith’s ownership of the property was legitimate and that any informal family arrangements did not create enforceable legal obligations. He suggested that the court should recognize Judith’s right to manage the property independently. As the legal proceedings continue, the outcome will likely have far-reaching implications for the Bisiker family. The resolution of this dispute may determine whether the cherished New Forest estate remains within the family or is sold to an external buyer. For now, the sisters remain locked in a contentious battle, each vying to uphold what they believe is their rightful claim to a piece of their shared past.
