Javier Castro knew he was dying – he had refused a life-saving blood transfusion on religious grounds – and talked about making a will when his two brothers visited him in hospital. They had no pen and paper to hand, so wrote out a will on a tablet device, which Castro and the brothers signed on the tablet. An Ohio county probate judge held that the will was valid: under state law, a will must be a written document that is signed and witnessed (Estate of Castro, Lorain County Probate Court, 27 June 2013).
