Section 45: Declaration by testators.

1 The declarations of a deceased testator as to his testamentary intentions and as to the content of his will, are admissible when-
a his will has been lost, and when there is question as to what were its contents; or
b the question as to whether an existing will is genuine or was improperly obtained: or
c the question as to whether any and which of more existing documents than one constitute his will.

2 In the cases mentioned (1) of this section, it is immaterial whether the declarations were made before or after the making or loss of the will.
