Validity of a Will

How to challenge the validity of a Will.

Challenging the validity of a Will is most commonly based on following grounds:

  • the Will-maker did not have testamentary capacity (not able to understand what a Will is, what assets they had to leave or who they wish to distribute to)
  • the Will-maker signed the Will under duress (an overbearing of the testator’s will)
  • the Will was not executed according to law (a written document signed in presence of witnesses), or
  • there is another Will that was executed later.

How to challenge the validity of a Will

Any person who wants to challenge the validity of a Will should lodge a caveat at the Probate Office. This is to try to prevent the grant of probate from being given.

It is important to act immediately, as the executors of the Will may have already lodged an application with the Probate Office.

A caveat shall expire 6 months after it is lodged, however the caveator (person challenging the Will) may renew the caveat if necessary.

The registrar will notify the caveator when the court receives an application for probate. The caveator has 30 days to file a statement of grounds of objection to the grant before the caveat expires. This statement is filed with the court registrar.

The caveator then has 7 days to make an application to court for directions. If this is not done within 7 days, the Will-maker's representative may apply to the court for directions.

A directions application is made by way of a summons. A date will then be set down for a hearing of the challenge. The hearing must not take place less than 7 days from the date when the application is filed with the Probate Office.
