Succession Act 1981

A will or part of a will that has been revoked is revived by re-execution or by execution of a will that shows an intention to revive the will or part.

A revival of a will that was partly revoked and later revoked as to the balance only revives the part of the will most recently revoked.

Subsection (2) does not apply if a contrary intention appears in the document that revives the will.

A will that has been revoked and is later entirely or partly revived is taken to have been executed on the day on which the will is revived.
