A 70-year-old landlord allowed a woman to stay in his property for 10 years with the understanding she'd maintain it and pay bills. When he asked her to leave, she falsely accused him to the police and then filed a court case claiming to be a tenant with a verbal agreement, despite having no rent receipts. The advice suggests she cannot prove tenancy and, even if considered a tenant, her tenancy has been terminated. The landlord should issue a legal notice for possession and then pursue eviction and damages through the courts, ideally with the help of a local solicitor.
