Finding you've been left out of a loved one's will or received inadequate provision can be devastating. If you're considering contesting a will in NSW, understanding the critical deadlines and legal requirements is essential to protect your rights.


In NSW, you have just 12 months from the date of death to file a family provision claim - miss this deadline and you could permanently lose your right to contest. The process involves strict legal procedures, substantial evidence requirements, and significant costs that make expert guidance from experienced will dispute lawyers crucial.


This comprehensive guide covers who can contest a will in NSW, the essential deadlines you must meet, step-by-step procedures for challenging a will, required documents and evidence, and when to seek professional help. Whether you're an eligible family member, dependant, or beneficiary, this information will help you understand your options and take timely action to protect your interests.


Who Can Contest a Will in NSW


1. Eligible Persons Under the Succession Act


Not everyone has the legal right to contest a will in NSW. Under Section 57 of the Succession Act 2006, only specific categories of people are considered "eligible persons" who can make a family provision claim:


  • Spouses and de facto partners at the time of death
  • Former spouses of the deceased
  • Children of the deceased, including adopted children and certain step-children
  • Dependants who were wholly or partly reliant on the deceased
  • Grandchildren who were members of the deceased's household and dependent on them
  • Close personal relationship partners who lived with the deceased


Beyond family provision claims, other parties may challenge a will's validity, including beneficiaries named in current or previous wills, executors, and anyone with a legitimate interest in the estate.


2. When You Cannot Contest a Will


You cannot contest a will simply because you believe it is "unfair" or because you expected to receive more. Valid grounds for contesting a will in NSW include:


  • Inadequate provision for eligible persons (family provision claims)
  • Lack of testamentary capacity when the will was made
  • Undue influence or pressure on the testator
  • Fraud or forgery of the will
  • Improper execution not meeting legal requirements under Part 2.1 of the Succession Act 2006
  • The will is not the deceased's last valid will


Critical Time Limits for Contesting a Will


1. The 12-Month Deadline Rule


The most critical deadline when contesting a will in NSW is the 12-month time limit for family provision claims. You must file your claim in the Supreme Court of NSW and serve it on the executor within 12 months of the testator's death.


This deadline is strictly enforced, and missing it typically means losing your right to challenge the will permanently. The 12-month period applies to deaths occurring on or after 1 March 2009, when the current provisions of the Succession Act 2006 came into effect.


2. When Time Limits Begin


The 12-month countdown begins on the date of the testator's death, not when you discover the contents of the will or when probate is granted. Several factors can influence your capacity to contest within this timeframe:


  • Minor beneficiaries can only contest once they turn 18
  • Mental incapacity may extend the time limit in exceptional circumstances
  • Lack of knowledge about the death may be considered, but courts rarely accept this as sufficient cause for delay


3. Consequences of Missing Deadlines


Missing the 12-month deadline has severe consequences. If you fail to file within this period, you lose your legal right to contest the will. While executors may delay distributing the estate if notified of a potential claim within six months of death, once the 12-month period expires, beneficiaries will receive their distributions with certainty.


To protect your interests, it is advisable to seek legal advice and notify the executor of your intended claim as early as possible, ideally within six months of the testator's death to prevent premature distribution of estate assets.


4. Applying for Extensions After 12 Months


While possible, obtaining an extension beyond the 12-month limit is extremely difficult. You must demonstrate "sufficient cause" for the delay and convince the court that your claim has merit.


The court will only consider the extension application alongside the actual family provision claim, deciding both matters simultaneously. If the judge determines your underlying claim lacks merit, the extension will be refused. Factors the court considers include:


  • The length of the delay
  • Reasons for the delay
  • Strength of your potential claim
  • Prejudice to other beneficiaries
  • Whether estate assets have already been distributed


Essential Steps to Contest a Will


1. File a Probate Caveat First


Filing a probate caveat with the Supreme Court of NSW is a crucial protective step when contesting a will. This document prevents the court from granting probate, which would otherwise confirm the will's validity and allow the executor to distribute estate assets.


A caveat must be served on any known applicants for probate or administration. It remains in force for six months from filing and can be extended if necessary. However, the probate applicant may file a notice of motion to remove your caveat if they believe you lack legitimate interest in the estate.


The rules governing caveats are outlined in Part 78 Division 10 of the Supreme Court Rules 1970. Anyone with a legitimate interest in the estate, such as beneficiaries under different wills or family members eligible for provision, can file a caveat.


2. Notify the Executor of Your Claim


Early notification to the executor or administrator is essential for protecting your position. Your solicitor should formally notify them of your intention to contest the will, ideally within six months of death. This notification helps prevent premature distribution of estate assets and demonstrates your serious intent to pursue the matter.


Proper notification also opens the door for potential negotiation and settlement discussions, which can resolve disputes more efficiently and cost-effectively than formal court proceedings.


3. Commence Formal Court Proceedings


If negotiations fail, you must commence formal court proceedings by filing appropriate documents with the Supreme Court of NSW. For family provision claims, this involves filing a summons in the Family Provision List along with supporting documentation.


The court process requires serving a notice of proceedings on all parties who would be adversely affected by your claim. This notice must annex your statement of claim and any relevant wills. All proceedings are managed through the Probate and Family Provision List, with directions typically heard on Tuesdays.


Required Documents and Evidence


1. Court Filing Requirements


Several documents are mandatory when commencing will contest proceedings:


  • Summons seeking orders for provision or challenging validity
  • Affidavit of evidence by the plaintiff detailing their case
  • Plaintiff's notice naming all eligible persons
  • Solicitor's affidavit estimating legal costs
  • Statement of claim outlining grounds for challenge and desired outcomes


These documents must be properly prepared and served according to Supreme Court Rules to ensure your case proceeds smoothly through the court system.


2. Evidence Needed for Different Contest Types


The type of evidence required depends on your grounds for contesting:


i. Medical evidence is essential when challenging testamentary capacity, including psychiatric assessments, GP records, and specialist reports demonstrating the testator's mental state when making the will.


ii. Financial records, correspondence, and witness testimonies support claims of undue influence, showing how others may have pressured or manipulated the testator.


iii. Expert testimonies from handwriting analysts or forensic specialists are crucial for fraud or forgery allegations, providing technical evidence about document authenticity.


iv. Financial documentation proving your relationship with the deceased, contributions to their welfare, and current financial needs supports family provision claims.


3. Legal Cost Estimates


Will contests can be expensive, with legal fees potentially reaching tens of thousands of dollars depending on case complexity. Court filing fees, expert witness costs, and potential liability for the other party's legal costs if unsuccessful add to the financial burden.


Your solicitor must provide a cost estimate affidavit as part of the court filing requirements, helping you understand the financial commitment involved in pursuing your claim.
