Do You Need to Update Your Will After Buying a House in Australia?

Buying a home is one of the biggest financial steps most Australians take. It is also one of the clearest prompts to check whether your Will still matches your life.

Will Hero provides general information and online Will preparation tools; we are not a law firm or financial adviser. This article explains common issues in plain language. For title changes, tax, or complex family structures, speak to a qualified solicitor or adviser.

Three things to confirm before you update your Will

Before you draft or revise anything, gather these basics:

1. How title is held — joint tenants, tenants in common, or sole owner (see how to check below)
2. Mortgage status — whether a loan is secured against the property and who would inherit that debt
3. Super nominations — binding or non-binding death benefit nominations are separate from your Will (learn more)

Does buying a house automatically update your Will?

No. When you settle on a property, you acquire a new asset. Your Will does not rewrite itself to include it.

If you already have a Will, it keeps working as written until you update it or make a new one. If you have no Will, intestacy rules decide who inherits—not you.

That is why conveyancing and estate planning are separate steps. Completing a purchase is a practical time to open your Will (or start one if you have been putting it off—see why you shouldn’t put off writing your Will).

Why a new home often makes your old Will outdated

Even a Will that was fine a few years ago may not fit after you buy property.

Common gaps include:

• No mention of real estate — everything may fall into a generic residue clause without reflecting how important the home is to you
• An old address or sold property — a specific gift of a former home may adeem (fail) if that property no longer exists
• Wrong beneficiaries — relationships, children, or priorities may have changed since you signed
• A much larger estate — your home may shift the balance between partner, children, or other beneficiaries
• Buying with a partner — your earlier single-person Will may not match a joint purchase or shared plan

An outdated Will can create problems similar to having no Will at all. See common mistakes when making or updating a Will for examples.

Is your Will still valid after selling a house?

Your Will may still be legally valid, but that does not mean it still works as you expect. If you sold one property and bought another—or removed a specific gift from your life without updating your Will—the document may reference assets or addresses that no longer exist. Treat selling, upgrading, or downsizing as a trigger to review and update, not assume everything still fits.

After buying a home, check your Will for:

Use this as a practical checklist:

• Does your Will reflect your current property (not only old assets)?
• Are beneficiaries still the people you want for your largest asset?
• Is the home held as joint tenants or tenants in common—and does that match your plan?
• Do you want a specific gift of the house, or should it form part of your residue?
• Are executors and backup beneficiaries still appropriate?
• If you bought with a partner, do both Wills still align?

Will vs title: who gets the house?

Your title often matters as much as your Will wording—especially for the family home.

Joint tenants: If you own as joint tenants with someone else (often a spouse or partner), your interest usually passes to the survivor when you die. That happens by the right of survivorship, outside your Will.

Tenants in common: Each owner holds a separate share. Your share can generally be left under your Will, which can help where you need to balance a partner’s security with gifts to children from another relationship.

Changing how you hold title has legal, lending, and sometimes tax consequences. Treat it as a decision to make with professional advice, not a DIY fix. For blended families, see our blended family Wills guide.

How to check how you hold title

Do not guess. You can confirm your ownership structure by:

• Checking your Transfer of Land (or equivalent) from when you bought the property
• Asking your conveyancer or solicitor who handled settlement
• Reviewing your mortgage documents or property rates notice (helpful, though not always as precise as the title itself)
• Ordering a title search through your state or territory land registry—for example, NSW Land Registry Services, Land Use Victoria, Titles Queensland, Landgate (WA), or the equivalent in your state

The wording on title—joint tenants vs tenants in common—is what counts, not what you assumed at purchase.

Specific gift or part of your residue?

You can deal with property in your Will in different ways.

Specific gift: You leave a particular property (or your share) to a named person—for example, a child or partner. This can be clear, but if the property is sold or replaced, the gift may adeem (fail) unless your Will is updated or worded to cover replacements.

Residue: Your home forms part of everything left after debts, funeral costs, and specific gifts. Simpler for many people, but all residuary beneficiaries share in the home’s value—not necessarily ideal if you wanted one person to receive the house itself.

Leaving property to children: You can often gift your share or the whole home to children if title allows it—but joint tenancy with a partner, mortgage debt, and blended-family dynamics all affect what works in practice. Get advice where the plan is not straightforward.

Mortgages and inherited property

If there is a mortgage, the person who inherits the property usually inherits the debt secured against it as well—unless your Will directs the estate to pay off that loan. In most Australian states, a debt attached to a specific gift of land stays with the property unless you say otherwise.

That does not mean the beneficiary must keep the house, but it does mean they inherit the asset subject to the mortgage. Get advice if the loan is large or your plan depends on the home being debt-free.

First home, upgrade, or investment property

First home: Many first-time buyers have never had a Will, or have a very simple one. Buying often coincides with marriage, children, or moving in with a partner—review everything together.

Upgrading or downsizing: You may have sold one property and bought another. Update or remove specific gifts tied to the old address so your Will matches reality and gifts do not adeem.

Investment property: Ownership structure (sole name, joint, trust, or entity) may affect what your Will can control. This article focuses on typical owner-occupier situations; investment and business structures need tailored advice.

When to update vs when to make a new Will

Updating may be enough if your Will is relatively recent, your family structure is unchanged, and you mainly need to add property, adjust beneficiaries, or refresh executors.

A new Will is often better if:

• your current Will is many years old
• you have married, separated, divorced, or had children since it was signed
• it references assets or people that no longer exist
• you and a partner need aligned mirror Wills after buying together

In Australia, minor informal changes are risky. An updated Will (or valid codicil) must meet your state’s signing and witnessing rules under legislation such as the Succession Act in NSW and equivalent Acts elsewhere. See how to make a legally valid Will in Australia.

What else to review at the same time

Buying a home is a good moment for a wider estate-planning tidy-up:

• Superannuation nominations — often separate from your Will
• Life insurance — check who benefits and whether that still fits
• Partner’s Will — avoid contradictory instructions
• Storage — tell your executor where the signed Will is kept
• Regular reviews — even without another purchase, a check every few years helps

What to know before starting your Will Hero draft

Will Hero makes it straightforward to document your wishes, but it relies on you knowing what you own and how it is held. Before you start your Will online, confirm:

• whether you hold the property as joint tenants, tenants in common, or sole owner
• whether a mortgage would pass with the property
• who should benefit if your plan differs from default survivorship or intestacy rules

Online Will tools—including Will Hero—generally treat property as part of your estate in the document. They cannot change how title works on the land register. Getting the ownership type right upfront helps your Will match what you intend.

Final thoughts

A new set of keys is a milestone worth celebrating. It is also a sensible prompt to ask: If something happened to me tomorrow, would my Will still do what I intend for this home and the people I care about?

For many Australians, the answer after buying property is not yet. Updating or creating a Will does not need to be complicated—but it does need you to understand how your home is held. Will Hero offers guided, state-aware templates, visual planning tools, and Review My Will to help you document your wishes clearly once you have confirmed your title and priorities. When ownership, family, or tax is more complex, a solicitor remains the right next step.
