White_v_Driver
White v Driver was a case decided in 1809 concerning a challenge to a will on the grounds of insanity. It laid down that if there was a previous history of insanity, the burden of proof lies in proving the sanity of the testator when making the will. The case was decided at Doctor's Commons under civil law, but continues to be quoted in the UK, Australia[1] and in the US as recently as 2010.[2]
