Unsure how to change a will in Australia?

Can a will be changed?
Yes, a will can be changed during a person's life, but the process and legal requirements depend on the circumstances and which Australian state or territory you're in. This guide explains the different ways a will can be altered, what steps are involved, and what you should know before making changes.
How wills can be changed in Australia
Once you've made a will, circumstances may change. You might want to leave assets to different people, add new beneficiaries, or update your executor. The good news is that your will is not permanent. There are established legal methods to modify it.
The most common ways to change a will involve either making a formal amendment (called a codicil) or creating an entirely new will. A codicil is a legal document that allows you to amend a will without starting from scratch. It must meet the same formal requirements as the original will, including being witnessed correctly and signed by you. This approach works well for minor changes, such as updating a beneficiary's details or adding a specific bequest.
Alternatively, if your changes are extensive, you may choose to revise a will completely by creating a new one. This approach can be clearer and avoids confusion about multiple documents. When you update will provisions this way, the new document typically cancels the previous one entirely.
Regardless of which method you choose, Australian law requires that any changes to a will follow strict procedures. This exists to protect your intentions and prevent disputes later. Without proper formality, changes may not be legally recognised, which could create uncertainty about what you actually wanted.

Common situations
You may be thinking about changing your will if:
Your family circumstances have changed (marriage, divorce, new children, or grandchildren)
Your financial situation has improved and you want to benefit additional people
You want to remove or add a beneficiary
Your executor is no longer able or willing to take on the role
You want to change how your assets are distributed
You've had a significant change in your relationship with a family member
You want to leave gifts to charities or organisations not mentioned originally
Your business ownership or property has changed substantially
What can go wrong
If you try to change a will informally, without following valid will requirements, the changes may not be recognised by the courts. This can lead to disputes among family members and may result in your estate being distributed according to the old will, regardless of your current wishes. Even worse, unclear or improperly executed changes can trigger someone contesting a will, resulting in costly legal battles and delays in settling your estate.
What to consider
Have your circumstances changed significantly since you last made or updated your will?
Are your changes minor (suitable for a codicil) or extensive (requiring a new will)?
Do you understand the difference between amending a will and creating a new one?
Is your current executor still appropriate for the role?
How soon do you need these changes to take effect?
Would a lawyer's guidance help you avoid future disputes?
Are there tax implications you should be aware of before making changes?

Changing your will FAQs
You can update your will by creating a new will that replaces your old one, or by adding a codicil, which is a formal amendment. The method you choose depends on how significant the changes are. For major changes, creating a new will is often simpler. A licensed lawyer can help you ensure any updates meet all legal requirements and properly reflect your wishes.
Yes, you can generally change your will at any time while you have mental capacity. Changes must be made formally to be legally valid, either through a new will or a codicil. Your capacity to make decisions and understand the nature of your assets is important. Speak with a licensed lawyer if you are uncertain about whether your circumstances allow for a valid change.
A codicil is a formal document that amends or adds to an existing will without replacing it entirely. It is useful for minor changes, such as updating a beneficiary or property description. Like a will, a codicil must meet specific legal requirements to be valid. If you are making significant changes, creating a new will may be clearer and less complicated.
You can revoke a will by creating a new will that expressly states the old one is revoked, or by creating a codicil that formally revokes specific provisions. The method matters for legal validity. A licensed lawyer can advise on the most appropriate way to cancel your will and ensure no confusion arises later.
The cost of updating a will depends on the complexity of changes, whether you use a lawyer, and your location. Creating a simple codicil may cost less than drafting a new will. Legal fees vary, so it is worth obtaining quotes from a few licensed lawyers. We can connect you with a licensed lawyer who can provide advice specific to your situation.
