Challenging the Validity of a Will
Challenging a Will means questioning if the document itself is legally sound and truly represents the final wishes of the deceased. This is distinct from a family provision claim, which argues for a larger share from a valid Will. A validity challenge asserts that the Will should be disregarded entirely.
The most common grounds for a challenge include a lack of testamentary capacity (the person was not of sound mind), that they were subject to undue influence or coercion, or that the Will is a forgery or was procured by fraud. Proving these grounds requires strong evidence and expert legal argument.
Eligibility & First Steps to Challenge a Will
To challenge a Will’s validity, you must have a legal interest in the estate. This typically means you are a beneficiary in the current Will, were a beneficiary in a previous Will, or would be entitled to inherit if the person had died without any Will (intestate).
The first crucial step is often to lodge a probate caveat with the Supreme Court of NSW. This prevents the executor from obtaining a grant of probate and distributing the estate assets while the validity of the Will is investigated. Seeking timely legal advice is essential to protect your position and navigate this complex process.

Challenging a Will (Validity) FAQs
What does it mean to challenge a Will?
Challenging a Will means you are questioning its legal validity. You are arguing that the document itself is flawed and should not be considered the true last testament of the deceased.
What is the difference between challenging and contesting a Will?
Challenging a Will disputes its validity (e.g., claiming it’s a forgery or the maker lacked capacity). Contesting a Will (a family provision claim) accepts the Will is valid but argues it fails to make adequate provision for a particular person.
Who can challenge the validity of a Will?
Generally, you can challenge a Will if you have a legal interest in the outcome. This typically includes beneficiaries named in the current or a previous Will, or those who would inherit if the person died intestate (without any Will).
What are the main grounds for challenging a Will's validity?
The most common grounds are: the will-maker lacked testamentary capacity (was not of sound mind), was subject to undue influence or coercion, the Will is a forgery, or the will-maker did not know and approve of its contents.
How do you prove a will-maker lacked testamentary capacity?
You must show that at the time of signing, the will-maker did not understand the nature of a Will, the extent of their assets, or their moral obligations to potential beneficiaries, often due to conditions like dementia or delusion.
What is "undue influence" in a Will challenge?
Undue influence means proving the will-maker was coerced to such an extent that the Will reflects the influencer’s wishes, not their own. This requires evidence of more than just pressure or persuasion.
Is there a time limit to challenge the validity of a Will?
There is no strict statutory time limit for challenging a Will’s validity. However, it is crucial to act as soon as possible, preferably before a grant of probate is issued, as delays can complicate proceedings and the recovery of assets.
What happens if a Will is successfully challenged and found to be invalid?
If a Will is declared invalid, the court will then look for a previous valid Will. If one exists, the estate is distributed according to that earlier Will. If there is no earlier valid Will, the estate is distributed according to the laws of intestacy.
Who pays the legal costs in a Will challenge?
The court has discretion over legal costs. If a challenge is reasonable and justifiable, the court may order that the legal costs for all parties are paid from the deceased’s estate. However, this is not guaranteed.
