What makes a will legally valid?

Legal requirements for a valid will in Australia

A will is a legal document that sets out how you want your assets distributed and who should manage your estate after your death. Creating a valid will generally involves following specific rules established by Australian law. Where these requirements are not met, a will may be challenged and could be declared invalid.

When a will is drafted, it generally needs to meet particular formal conditions. These legal requirements for a will generally exist to support a person's intentions and to reduce the likelihood of disputes among family members. They also help courts confirm that the document genuinely reflects a person's wishes and that the person had the mental capacity to make such decisions.

The core requirements generally include having testamentary capacity (the mental ability to understand the document), the will being in writing, and the will being signed with witnesses present. An enforceable will generally also demonstrates that the person making it acted of their own free will, without undue influence or pressure from anyone else. Different rules apply in different circumstances, and what makes a will legally valid can depend on factors like when it was made, your age, and whether you've made earlier wills. Being familiar with valid will requirements is something people often relate to avoiding potential problems and to having their wishes legally protected.

Key points

• Testamentary capacity is generally required to make a will.

• Signing a will with witnesses is generally a legal requirement.

• An invalid will cannot be enforced by the courts

• A will generally needs to be in writing (not spoken or video-recorded).

• A person making a will generally needs to act voluntarily without pressure or influence.

• Changes to laws can affect the validity of older wills

Common situations

You may be thinking about creating a will if:

• You've recently married, entered a de facto relationship, or separated

• You've bought a home or built up savings and investments

• You have children and want to appoint a guardian

• You own a business and need to plan for succession

• You want to leave money or property to specific people

• You have assets in multiple states or countries

• Some people consider a will as relating to reducing the chance of family disputes after death.

• Some people consider a will when entering retirement and wishing to formalise their wishes.

• Some people consider a will after experiencing a significant change in their financial circumstances.

When wills are not properly drafted or signed, disputes often arise. For example, if witnessing a will hasn't been done correctly, family members may argue that the document isn't valid. Unclear language can also lead to confusion about what a person intended, which may cause delays in distributing an estate and potentially costly legal disputes.

Similarly, where there are questions about whether a person had the proper mental capacity when signing, or where someone suggests pressure was involved, contesting a will may become more likely. These situations can create stress for families and may significantly increase legal costs.

What to consider

• Have you listed all your major assets and liabilities?

• Who do you trust to act as your executor and make decisions?

• Are there blended family situations that need careful planning?

• Do you understand the legal requirements in your state or territory?

• Would a simple will or more complex estate planning better suit your circumstances?

• What documents or information does your executor need to access your assets?
