Tasmanian Numbered Acts19. How a revoked will may be revived
(1) A will or part of a will that has been revoked is revived by re-execution or by execution of a will showing an intention to revive the will or part.
(2) A revival of a will that was partly revoked and later revoked as to the balance only revives that part of the will most recently revoked.
(3) Subsection (2) does not apply if a contrary intention appears in the reviving will.
(4) A will that has been revoked and later
revived, either wholly or partly, is taken to have been executed on the date
on which the will is revived.
