Before admitting to
proof a will that appears to have been signed by a blind or illiterate
testator or by another person by direction of the testator, or which for any
other reason gives rise to doubt as to the testator having had knowledge of
the contents of the will at the time of its execution, the Registrar shall
satisfy himself that the testator had such knowledge.
