(1) The court must not include an interlineation in or alteration to a will in the probate or letters of administration unless the interlineation or alteration—(a) was in the will when the will was made; or(b) if made afterwards—was made and attested in a way required by law; or(c) was made valid by the remaking of the will or a later codicil.
(2) If it is not shown when the alteration was made, and the words altered can, on inspection, be easily worked out, the altered words may be included in the probate or letters of administration.
(3) If the erased words may have been of importance, the erasure must be explained by evidence.
(4) In this rule—
"alteration" includes erasure and obliteration.
