What is the outcome when a testator changes will provisions under duress?

When a testator changes will provisions under duress, those changes are considered voidable at the request of an interested party. This means that while the changes are not automatically invalid, they can be challenged and potentially set aside if it can be demonstrated that the testator was coerced into making the changes against their free will.

Duress involves a threat or pressure that overrides the testator's ability to make an informed and voluntary decision regarding their testamentary intentions. Since the essence of a will is to reflect the true intent of the testator, any changes made under duress do not authentically represent that intent. Thus, interested parties—such as beneficiaries or heirs—can contest the validity of those provisions. If successful in proving duress, the court may void those particular changes, effectively restoring the will to its prior state.

Overall, the fact that the changes are voidable means there is room for legal contestation and potential correction, distinguishing it from situations where changes might be completely invalid or without any legal effect.
