The structure of British families are increasingly complex which can lead to unusual legal situations coming before the courts particularly in the context of a disputed inheritance. One such case was the case of Terry Marley. At age 15 years he moved in with into the family home of his best friends Michael and Terry Rawlings and their parents. It was only expected to be a temporary arrangement but he ended up staying for 30 years and caring for Mr and Mrs Rawlings in their old age. Mr and Mrs Rawlings died leaving wills bequeathing everything to Mr Marley and nothing to their sons. Mr and Mrs Rawlings had inadvertently signed each other's wills and their sons sort to overturn the wills, and claim the inheritance on the basis of an intestacy, on the basis that they were not properly executed but unusually in this case the court upheld the validity of the wills.
