Do I Need a Will If I'm Single in Australia? (2026 Guide)

If you are single—no spouse, or no children—it is easy to assume a Will is not urgent. In reality, estate planning for singles in Australia is often more important: there is no single obvious heir, and who inherits if you die single without a Will follows intestacy rules and a pre-set legal hierarchy, not your informal preferences. A Will is how you choose executors, beneficiaries, backups, and gifts (including to friends or charities) instead of statutory distribution.

What is intestacy?

Intestacy is the legal process that applies when you die without a valid Will (or without a Will that fully deals with your estate). Your estate is distributed under a fixed hierarchy in your state or territory’s succession legislation—not according to conversations, fairness, or who you were closest to in life.

Single in Australia: Will vs no Will

What happens if you die single without a Will in Australia?

If you die without a valid Will, your estate (assets that pass under your Will and estate rules) is dealt with under intestacy—each state and territory has its own succession Act that sets who inherits in what order under statutory distribution.

While each jurisdiction differs in detail, the general pattern across Australia is broadly consistent when someone dies without a spouse or children:

• Parents (if living), or
• Siblings (and sometimes their descendants), or
• More distant relatives (for example nieces, nephews, cousins—depending on the statute and who survives you).

Friends, favourite charities, and pets as beneficiaries are not part of that statutory list. De facto partners may have strong rights in some cases—including under family provision claims and, in certain situations, under succession rules where a qualifying relationship exists—but outcomes are not automatic, and relying on default rules can create uncertainty. A Will, and sometimes other documents (such as super nominations), is how you make intentions clear.

Without a Will you also do not appoint an executor. Instead, someone may need to apply for letters of administration so a court-appointed administrator can deal with your estate—which may not be the person you would have chosen.

Who gets your assets if you are single and have no Will?

If you are single and die intestate, distribution follows a strict legal hierarchy in your state or territory. For example (simplified):

• If parents are alive, they may inherit some or all of your estate (depending on the rules).
• If not, siblings may be next.
• If they are not alive, the estate may pass to more remote relatives according to the Act.

That can produce unintended outcomes, especially if:

• You are closer to friends than to extended family.
• You are in a relationship that does not match how intestacy or claims might treat a partner—rules vary, and certainty usually comes from proper planning.
• You would rather support a charity or a specific person who is not in the statutory list.

For example, if you would prefer your estate to go to a close friend or a charity, intestacy rules in Australia will not give effect to that wish on their own; assets may instead pass to more remote relatives you rarely see.

A Will is how you decide who benefits—not only the default order under the law.

Why being single does not always mean your estate is simple

It is common to assume that no partner and no kids equals “nothing complicated.” Often the opposite is true: there is no obvious default beneficiary, so you need to choose who receives your estate and what happens if those people cannot inherit.

That might include:

• Leaving a share to siblings, with a gift over to their children if they predecease you.
• Providing for friends or others who rely on you (where you choose to include them in a Will).
• Naming a charity as a residuary or backup beneficiary—see how to leave money to a charity in your Will in Australia.
• Making arrangements for pets: they are property, so you cannot leave money directly to an animal; you typically appoint a carer and may include a gift or direction to support their care. For more on choosing a carer, see things to consider when choosing a pet guardian for your Will.

In practice you are often designing layers: who receives first, who is backup, and where assets ultimately go if earlier gifts fail. Getting that structure right reduces the risk of partial intestacy or disputes.

Why structuring a Will can matter more when you are single

For many single people, a Will is not only “who gets my stuff”—it is a plan across scenarios.

1. Layered beneficiaries

You may want:

• A primary beneficiary (for example a sibling).
• A backup (for example their children).
• A final fallback (for example a charity).

See Why you need backup beneficiaries in your Will for how backups work, why they matter, and what to avoid when you are stacking layers like this.

Without clear wording, your estate may not follow that path—and gaps can push assets back toward intestacy-style outcomes.

2. Relationships the law does not automatically mirror

You might want to recognise friends, a partner, family members who are not next-of-kin, or organisations. Those outcomes generally need to be written into a Will (and you should consider whether other documents or nominations are needed—for example super).

3. Clarity reduces friction

If wishes are vague:

• Executors may face uncertainty.
• Family may disagree on what you “would have wanted.”
• Delays and disputes can add cost and stress.

A clear Will does not prevent every conflict, but it removes a lot of guesswork.

When a Will is especially important if you are single

You should strongly consider making or updating a Will if:

• You have savings, property, or investments.
• You want to leave assets to friends, a partner, or charities.
• You have pets and want a carer and resources considered.
• You want to choose your executor (and backups). How to Choose the Right Executor for your Will explains what executors do and how to pick someone suitable.
• You are planning overseas travel—why you should make a Will before you travel overseas covers why this is a common trigger to make or update a Will.
• You want to decide what happens if a primary beneficiary dies before you.

Being single often means more deliberate planning, not less, because there is no “obvious” single heir under your wishes.

What should a single person include in a Will?

A well-structured Will often includes:

• Executors (and substitute executors).
• Specific gifts (optional).
• Residual estate clauses—who receives what is left.
• Primary and backup beneficiaries at each stage.
• Pet care directions where relevant.

Will Hero’s Will Provisions library offers lawyer-reviewed wording for common situations—executors, specific gifts, residue, pet arrangements, and substitute beneficiaries—so those pieces are spelled out rather than left implicit.

The residual clause and backups are often the most important part: they keep your plan coherent if circumstances change.

Can a single person make a Will online in Australia?

Yes. An online Will can be legally valid in Australia when it meets the same formal requirements as any other Will: properly drawn, signed, and witnessed according to your state or territory. Platforms are built to guide you through those steps, including state-appropriate witnessing. Read more in our guide to whether an online Will is legal in Australia, and see how it works before you start. After drafting, execution matters: follow how to sign and witness your Will correctly and avoid common mistakes people make when making a Will. Will Hero’s Visual Will shows your plan as you build it—useful when you are layering primary beneficiaries, backups, and fallbacks instead of a single heir.

How often should you update your Will if you are single?

As a general guide, review your Will every 2–3 years, or sooner when something major changes: assets, relationships, moving state, beneficiaries, or who you want as executor. Keeping it current reduces the chance your document no longer matches your life.

Final thought: Being single can mean flexibility in how you structure your estate—but without a Will, you may lose control over who inherits and who administers your estate (instead of a chosen executor, a court-appointed administrator may need to step in). Creating a Will puts those choices in your words, not only in default statutes.
