Challenging the Validity of a Will
A will may be challenged if there are concerns regarding its validity. Under Australian law, there are several grounds for questioning a will’s validity, and a successful challenge can lead to the will being deemed void. Common grounds for challenging the validity of a will include:
-
Lack of Testamentary Capacity: To make a valid will, the testator (the person creating the will) must have had testamentary capacity, meaning they understood the nature of the will, the extent of their assets, and the impact of their decisions. A will can be challenged if there is evidence that the testator lacked capacity at the time of making the will, often due to conditions like dementia or other cognitive impairments. Legal assessments and medical records are often key evidence in these cases.
-
Undue Influence: If someone exerted undue influence over the testator, causing them to make decisions they would not otherwise have made, this can be grounds to challenge the will. Undue influence requires evidence that the testator was coerced or manipulated into making decisions in the will that do not reflect their genuine intentions.
-
Fraud or Forgery: A will may be invalidated if there is evidence it was created through fraud or forgery. Fraud can occur if the testator was deceived into signing the document, while forgery involves falsifying the testator’s signature or altering the will without their knowledge. These cases often require forensic examination and expert testimony.
-
Failure to Meet Legal Formalities: Australian wills must adhere to strict formalities. Typically, the will must be in writing, signed by the testator in the presence of two independent witnesses, and reflect the testator’s intentions. If these formalities are not met, the will can be challenged, although courts have discretion to uphold informal wills if there is strong evidence that the testator intended the document to serve as their will.
At BlackBay Lawyers, we work with our clients to examine potential grounds for challenging a will’s validity. We thoroughly assess each case, gathering the necessary evidence to pursue or defend against a challenge, with the aim of achieving a fair outcome.
