Marley v Rawlings and another [2014] UKSC 2; [2014] WLR (D) 18
A will did not have to satisfy the requirements for formal validity prescribed by section 9 of the Wills Act 1837, as amended, or have the testator’s knowledge and approval before it could be treated as a “will” which was capable of being rectified under section 20 of the Administration of Justice Act 1982.
