Will Kits Australia: Complete Guide to DIY Wills, Legal Validity & Better Alternatives 2025

This comprehensive guide covers everything you need to know about will kits in Australia: their legal validity, real court cases, product comparisons, state-by-state requirements, and when to choose better alternatives.

Are Will Kits Legal in Australia?

Yes, will kits can create legally valid wills in Australia, but only if executed correctly. The document must meet the formal requirements of your state's succession legislation:

• NSW: Succession Act 2006 (s.6)
• VIC: Wills Act 1997 (Vic) (s.7)
• QLD: Succession Act 1981 (s.10)
• SA: Succession Act 2023 (SA)
• WA: Wills Act 1970 (WA)
• TAS: Wills Act 2008 (Tas)

Key Point: The legal validity of a will depends on proper execution, not whether it was prepared by a lawyer. However, the complexity lies in getting every detail right.

Real Court Cases: When Will Kits Fail

Understanding how courts deal with problematic wills helps illustrate the risks of DIY approaches.

Re Yu [2013] QSC 322, The iPhone Video Will

Facts: Karter Yu, facing imminent death, recorded a video on his iPhone detailing how he wanted his estate distributed. The video was not witnessed in the traditional sense.

Decision: The Queensland Supreme Court granted probate to the iPhone video, finding it constituted an "informal will" under s.18 Succession Act 1981 (Qld).

Key Quote: Lyons J held that the deceased "intended the document to constitute his will" and it demonstrated clear testamentary intent.

Lesson: While informal wills can be validated, this required a court application and legal costs. A proper will would have avoided this uncertainty.

Queensland Courts Reference

Informal Documents Are Not Guaranteed to Be Accepted

When a will kit is not completed correctly, the document may not meet the formal execution rules. Courts in every state have a "dispensing power" to admit an informal document to probate, but only where they are satisfied it genuinely represents the deceased's intentions. That is not guaranteed: where the evidence of intent is unclear or the documents are inconsistent, the application can be refused and the estate distributed under intestacy instead.

Ambiguous Wording Is Costly to Untangle

Generic will-kit language often creates ambiguity about how assets should be shared. When the wording is unclear, the executor or the court may have to work out what the will-maker meant, which causes delay, legal costs, and a result that may not reflect what was actually wanted.

Banks v Goodfellow (1870), Still the Testamentary Capacity Test

While this is an old English case, Australian courts still apply the Banks v Goodfellow test for testamentary capacity. A valid will requires the person to:

1. Understand the nature of making a will
2. Understand the extent of their property
3. Comprehend who might have claims on their estate
4. Be free from any disorder of mind that influences their decisions

Relevance to Will Kits: If you complete a will kit while unwell or confused, the will may be challenged on capacity grounds.

State-by-State Witnessing Requirements

All Australian states have similar but not identical witnessing requirements. Getting these wrong is one of the most common reasons will kits fail.

Core Requirements (All States)

State-Specific Variations

Remote Witnessing Process (Where Permitted)

For states allowing audio-visual witnessing:

1. Video call with both witnesses simultaneously
2. Share screen or hold document to camera
3. Sign while witnesses watch in real-time
4. Witnesses watch each other sign their copies
5. Post original to each witness for countersigning
6. Return all pages to will-maker for binding

Warning: Remote witnessing has specific technical requirements. Check your state's legislation for exact procedures.

When to Use a Will Kit (And When NOT To)

Will Kits May Be Appropriate If:

✅ You are single with no dependents ✅ You have straightforward assets (home, savings, superannuation) ✅ You want to leave everything to one or two clear beneficiaries ✅ You have no business interests or company shares ✅ There is zero risk of family disputes ✅ You have no international assets ✅ You understand the witnessing requirements perfectly

AVOID Will Kits If You Have:

❌ Blended family, Children from different relationships create complex distribution needs ❌ Business interests, Company shares, partnerships, and trading assets need specific provisions ❌ International assets, Property or investments overseas may require foreign law compliance ❌ Family member with disability, Special Disability Trusts and Centrelink implications apply ❌ Potential for disputes, If anyone might challenge, professional drafting is essential ❌ Superannuation complexity, Binding death benefit nominations need separate attention ❌ Previous wills, Proper revocation language is critical ❌ Digital assets, Cryptocurrency, online accounts, and digital property need specific treatment

Legislation and Official Resources

Will-making in Australia is governed by each state and territory's own succession legislation. The core statutes include:

• New South Wales: Succession Act 2006 (NSW)
• Victoria: Wills Act 1997 (Vic)
• Queensland: Succession Act 1981 (Qld)
• South Australia: Succession Act 2023 (SA)
