Challenging a Will: Grounds for Contesting in NSW

March 6, 2025

Introduction

Disputes over Wills can be complex and emotionally challenging, particularly when beneficiaries believe a Will does not accurately reflect the wishes of the deceased. In New South Wales, there are legal grounds for contesting a Will, and claimants must follow a structured process to challenge its validity. In this article, we will explore the legal grounds for contesting a Will, the process involved in challenging a Will in NSW courts, and the importance of legal representation in inheritance disputes.

Legal Grounds for Contesting a Will in NSW

Lack of Testamentary Capacity

A person must be of sound mind when making a Will. If the deceased lacked mental capacity due to dementia, illness, or cognitive impairment at the time of signing, the Will may be challenged on this basis. Medical records and witness testimony are often required to support such a claim.

Undue Influence or Coercion

A Will must be made voluntarily, without external pressure. If there is evidence that the deceased was coerced or pressured into making or changing a Will, it may be deemed invalid. Courts will assess whether the testator acted of their own free will when making their decisions.

Fraud or Forgery

A Will may be contested if it was altered, forged, or signed under fraudulent circumstances. This can include situations where someone misrepresented facts to the testator or where false documents were used.

Failure to Meet Legal Requirements

A Will must comply with the formal requirements set out in the Succession Act 2006 (NSW). If it is not properly signed, witnessed, or drafted, it may be considered invalid by the court.

Family Provision Claims

Under the Succession Act 2006 (NSW), certain eligible persons can contest a Will if they have been unfairly left out or have not received adequate provision. These claims are assessed based on financial need, the nature of the relationship with the deceased, and the overall fairness of the estate distribution.

The Process of Challenging a Will in NSW

Seeking Legal Advice

Before taking any action, it is crucial to obtain legal advice to determine whether a valid claim exists. There are strict timeframes for contesting a Will, so early legal intervention is essential.

Filing a Claim in the Supreme Court of NSW

Challenges to a Will are generally filed in the Supreme Court of NSW. For family provision claims, an application must be made within 12 months of the deceased’s passing.

Negotiation and Mediation

Many Will disputes are resolved through mediation rather than proceeding to a formal court hearing. Mediation allows parties to reach a mutually acceptable agreement while avoiding the costs and delays of litigation.

Court Proceedings (If Necessary)

If mediation does not resolve the dispute, the case proceeds to court, where a judge will determine whether the Will is valid and whether changes should be made to the distribution of the estate. The court may set aside the Will, order a new distribution of assets, or uphold the original terms.

The Importance of Legal Representation in Inheritance Disputes

Contesting a Will is a complex legal process, and having experienced legal representation ensures that:

  • The claim is supported by strong evidence, including financial records, medical reports, and witness statements.
  • All procedural requirements and deadlines are met to avoid delays or dismissal of the case.
  • Negotiations are handled effectively, increasing the likelihood of a favourable outcome without court intervention.
  • The claimant is properly represented in court if litigation becomes necessary.
