Estate Planning
Planning for the future is one of the most important steps you can take to protect your family. A key part of this is creating a valid Will to ensure your assets are distributed exactly as you wish. However, sometimes documents that don't meet the formal requirements of a Will are put forward as representing a person's final wishes. These are known as informal wills.
In New South Wales, the law has had to adapt to new forms of communication, leading to disputes over documents like handwritten notes, emails, and even text messages. Understanding the risks associated with informal wills is crucial for effective estate planning in Australia. While they can sometimes be accepted by a court, relying on them creates uncertainty and can lead to costly legal challenges for your loved ones.

What Makes a Will Formal?
To ensure your Will is legally binding, it must meet specific requirements. Under Section 6 of the Succession Act 2006 (NSW), a formal Will must be:
In writing: The Will must be a physical or electronic document.
Signed by the testator: You (the testator) must sign the document.
Witnessed: Two witnesses must be present when you sign, and they must also sign the Will in your presence.
These rules are in place to prevent fraud and to make sure the document truly reflects your testamentary intent—that is, your intention for the document to be your final Will.
When Can an Informal Will Be Accepted?
Life is not always straightforward, and the law recognises this. The Supreme Court has the power to accept a document as a valid Will even if it does not meet the formal requirements. This is sometimes called "dispensing power."
For an informal document to be accepted, the person seeking to have it validated must prove to the court that the deceased person intended for that specific document to act as their final Will. This is a high bar to meet and often requires significant evidence, which can be difficult and expensive to gather. The court will examine all the circumstances to understand the deceased’s true intentions.
Real-Life Cases of Informal Wills
Courts across Australia have seen numerous cases involving informal wills, each with unique challenges. These examples highlight the complexities and uncertainties involved.
The Handwritten Note
In some situations, a simple handwritten note has been presented as a person's final wishes. In the case of Borthwick v Mitchell [2017], a signed but unwitnessed note was found in the deceased’s diary. The note detailed how they wanted their estate to be divided. To determine if this was a valid Will, the court had to look at surrounding evidence. This included testimony from family members about the deceased's intentions and expert handwriting analysis. After careful consideration, the court decided the note was a true expression of the deceased’s final wishes and accepted it as their Will, overriding a previous formal one.
The Email Will
Digital communication has also entered the estate planning arena. In Yazbek v Yazbek [2012], an email sent to a friend outlined the deceased's wishes for his property. Although the email was informal and not signed in the traditional sense, it contained clear instructions. The court had to decide if the deceased intended for that email to be his final Will. Based on the detailed content and the context in which it was sent, the court ruled that the email was a valid testamentary document.
The Unsent Text Message
One of the most modern examples comes from a Queensland case, Re Nichol; Nichol v Nichol & Anor [2017]. An unsent text message was found on the deceased's mobile phone. The message was addressed to his brother and provided clear instructions on what to do with his house and ashes. Because the message was never sent, there was a major question about whether he truly intended for it to be his Will. The court examined his previous statements and relationships, concluding that the unsent message did represent his final wishes and accepted it as an informal Will.
These cases show that while courts can be flexible, relying on an informal document creates a significant risk of dispute.
Why You Should Prioritise a Formal Will
While these case studies are interesting, they also serve as a warning. The process of proving an informal Will is often long, stressful, and expensive for the family members left behind.
Here are the key reasons why obtaining legal advice for wills and creating a formal document is the most secure method of estate planning:
Clarity and Certainty: A formal Will, drafted by a legal professional, leaves no room for doubt about your intentions. It is structured to be clear and legally sound, reducing the risk of it being challenged.
Minimising Family Conflict: When your wishes are clearly documented, there is less potential for disagreements among your beneficiaries. Informal wills can easily create disputes as family members argue over what you truly intended.
Avoiding Costly Court Battles: Proving the validity of an informal Will requires a court application, which can be very expensive. These legal fees are often paid from the estate, meaning there is less inheritance left for your loved ones.
Peace of Mind: Knowing you have a legally binding Will provides peace of mind for both you and your family. You can rest assured that your affairs are in order and your wishes will be respected.
Securing Your Legacy
In an age of digital messages and quick notes, it might seem easy to type out your wishes and assume they will be followed. However, the legal landscape surrounding informal wills is complex and filled with uncertainty.
The most reliable way to protect your assets and ensure your family is cared for is to create a formal Will with the help of an experienced legal professional. This process ensures all legal requirements are met, your testamentary intent is clear, and your legacy is secure. Don't leave your family's future to chance. Taking the time to formalise your estate plan is a final act of care for the people who matter most to you.
