Unsure about contesting a will in Australia?

Overview of the grounds for contesting a will
Contesting a will means challenging its validity in court. There are specific legal grounds on which a will can be contested in Australia, such as lack of capacity, undue influence, or failure to follow proper legal procedures. Understanding these grounds can help you determine whether you may have a valid claim.
What challenging a will means in Australia
Challenging a will is a legal process that allows someone to question whether a will is valid or was properly made. Where a will appears to have been created improperly, the person making it lacked the mental capacity, or they were pressured into signing it, grounds for contesting a will may exist.
In Australia, there are specific legal reasons why a will may be challenged. These include issues such as undue influence (where someone pressured the testator into changing their will), lack of testamentary capacity, or problems with how the will was created and signed. Information about these grounds is something people often refer to when thinking about challenging a will or protecting one from being contested.
When someone contests a will, they're essentially asking a court to examine whether it should be recognised as a valid legal document. This is a serious matter that can take time and cost money. The person challenging the will, often called the challenger or contester, generally provides evidence to support their claim. This might involve medical records, witness statements, or expert testimony.
It's important to note that not just anyone can challenge a will. Generally, a person needs to have a direct interest in the outcome, such as being a beneficiary under an earlier will or being someone who would inherit if the current will were invalid.

Common situations
There are several circumstances in which you might consider contesting a will. These include:
A family member was excluded entirely, or received far less than expected, or the will contains changes that seem unfamiliar
Circumstances people sometimes describe include where the testator may not have been mentally capable of making decisions (lack of capacity).
Someone appears to have exercised undue influence over the person making the will
The will wasn't signed properly or doesn't meet legal formality requirements
There's a significant age gap between the testator and a beneficiary, or a new relationship existed
Medical evidence suggests the testator had dementia, mental illness, or cognitive decline at the time the will was made
A previous version of the will exists that differs significantly from the current one
If a will is successfully challenged and found to be invalid, significant consequences can follow. The estate may be distributed according to an earlier will, or if none exists, according to the rules of intestacy (where the law decides how assets are divided). This can mean lengthy court proceedings, substantial legal costs, and family conflict. In some cases, disputes may last for years.

What evidence do you have to support your claim?

How long ago was the will made? Time limits may apply to a challenge, connected to particular stages of proceedings.
What documents or witness accounts exist that support your position?
Are you prepared for the emotional and financial commitment of a legal process?
Would mediation or negotiation be worth exploring first?

Contesting a will FAQs
Valid grounds for contesting a will in Australia generally include lack of testamentary capacity, undue influence, fraud, or breach of duties by the person administering the will. The will may also be contested if it does not comply with formal legal requirements, such as proper signing and witnessing. Each situation depends on specific circumstances, and establishing grounds requires evidence. Speaking with a licensed lawyer is something people often do to understand whether a case may exist.
Undue influence occurs when someone improperly pressures or manipulates the deceased person into making a will that benefits that person. This may involve coercion, threats, or exploiting a position of trust or dependency. The person contesting the will must generally prove that the influence was substantial enough to affect the will's terms. Undue influence can be difficult to establish, and evidence from the time the will was made is often relevant.
Lack of testamentary capacity means the person making the will did not have sufficient mental ability to understand the nature of their assets, the people who would normally inherit, and the practical effect of the will. This may occur due to dementia, mental illness, or the effects of medication. The test focuses on the person's mental state at the time they made the will. A contested will may be set aside partly or entirely if capacity cannot be established.
Fraud in a will context means someone intentionally deceived the deceased person about the will's contents, or fraudulently created or altered the document. This might involve forging a signature, misrepresenting what the will says, or fabricating the entire will. Fraud is a serious allegation that requires strong evidence, such as expert handwriting analysis or witness testimony. If proven, fraud can result in the will being rejected entirely.
