Turner v Phythian  EWHC 499 (Ch),  MHLO 10
"Mrs Turner, with the support of several members of the Jolly family, asserts that the will is invalid on three grounds. The first ground is lack of proper execution. It is alleged that the will was not signed by Iris in the joint presence of the witnesses. ... The second ground is that Iris lacked mental capacity to make the will. ... The third ground is that Iris did not know or approve of the contents of the will. ... I find therefore that the contested will is invalid on two grounds; that Iris did not have mental capacity to make the will in August 2010 and that she did not know or approve the contents of the will."
