Bamber launched two unsuccessful lawsuits while in prison to recover a share of his family's estate. In 2003 he began a High Court action to recover £1.2m from the estate of his adoptive grandmother, Mabel Speakman, arguing that he should have inherited her home at Carbonnells Farm, Wix, Essex, and that he was owed 17 years' back rent from his cousins who were living there.[21] Speakman had cut Bamber out of her will when he was arrested, and most of the inheritance went to Pamela Boutflour, June Bamber's sister.[22] Boutflour subsequently moved into Carbonnells Farm with her husband, Robert.[21] In 2004 Bamber went to the High Court again to claim a share of the profits from the family's caravan site in Maldon. He had retained his shares after his conviction, but had sold them to pay the legal costs arising from his claim on his grandmother's estate. The court ruled that he was not entitled to any profit from the site because of his conviction
