Section 16

No obliteration, interlineation or other alteration made in any will after the execution thereof shall be valid or have any effect except so far as the words or effect of the will before such alteration shall not be apparent, unless the alteration shall be executed in the like manner as by this Act is required for the execution of the will.

A will referred to in subsection (1), with such alteration as part thereof, shall be deemed to be duly executed if the signature of the testator and the subscription of the witnesses be made in the margin or on some other part of the will opposite or near to the alteration or at the foot or end of or opposite to a memorandum referring to the alteration and written at the end or some other part of the will.
