Avoiding Executor Errors With an Accurate Retrospective Valuation

Introduction

When someone dies, the person named as executor suddenly inherits a long list of legal and financial responsibilities. One of the easiest to get wrong is working out what the deceased’s property was actually worth through an accurate property value assessment that reflects the relevant market conditions. The ATO, the Supreme Court and the beneficiaries all need a defensible answer to the same question: what was this property worth on the date the person died?

That figure doesn’t come from a council rates notice or a chat with the local real estate agent. It comes from a retrospective valuation — a formal assessment of market value as at a specific past date, prepared using the sales evidence and market conditions that existed at that time, not today’s.

For executors, getting this step wrong isn’t just an admin hiccup. It can lead to an incorrect capital gains tax position, an unfair split between beneficiaries, and disputes that end up with lawyers involved. This article looks at why an accurate retrospective valuation matters for executors, the mistakes that come up most often, and what a properly prepared valuation actually involves.

Summary

Executors are responsible for identifying and valuing the assets of a deceased estate, including any real property. Where the ATO or the Supreme Court needs the property’s value “as at date of death,” a current market appraisal isn’t the right document — the value has to be established for that specific past date using historical evidence, which is what a retrospective valuation does.

The most common executor errors are relying on a real estate agent’s appraisal instead of a formal valuation, using today’s value rather than the date-of-death figure, leaving the valuation until years after the event when evidence is harder to reconstruct, and failing to keep the report on file to support tax obligations or defend a decision if beneficiaries later disagree. A retrospective valuation prepared by a suitably qualified, independent valuer addresses each of these risks. It gives the executor a documented figure that can support the deceased’s final tax return, the beneficiaries’ future CGT calculations, and a fair division of the estate when dealing with property inherited after a loved one’s death. Getting it organised early, and keeping the report with the estate records, is the simplest way to avoid problems down the track.

What Is a Retrospective Valuation, and Why Do Executors Need One?

A retrospective valuation determines what a property was worth at a specific point in the past, rather than today. It’s also called a backdated or historical valuation. Instead of inspecting the property now and comparing it to current listings, the valuer works backwards: analysing the property’s condition and features as they existed on the relevant date, and using comparable sales and market data from around that same period.

For a deceased estate, the relevant date is almost always the date the person died. This is because assets held by a deceased person are generally treated, for both probate and tax purposes, as being valued and transferred as at that date — not the date probate is granted, and not the date the executor eventually gets around to organising a valuation (which can sometimes be months later).

This matters because property markets move. A home that was worth a certain amount when someone died two years ago may be worth noticeably more or less today. Using a current valuation instead of a date-of-death valuation can produce a figure that has nothing to do with what the ATO, the Court or the other beneficiaries are entitled to rely on.

Why the “Date of Death” Value Matters More Than Executors Expect

Probate and the Estate Inventory

When applying for a grant of probate, executors typically need to understand NSW probate application requirements, including information about estate assets and supporting documentation. Real property has to be included at its market value as at the date of death. An inflated or understated figure here can create problems later, particularly if a beneficiary or the Court later queries how the value was arrived at.

Fair Distribution Between Beneficiaries

If a will divides an estate between several people, or if one beneficiary is being allowed to keep the family home while others receive cash or other assets, the split needs to be based on an accurate figure. A rough guess, or a valuation done at the wrong time, can end up favouring one beneficiary over another, even unintentionally. That’s exactly the kind of thing that leads to disputes between siblings or other family members.

Capital Gains Tax for the Estate and Beneficiaries

Under Australian tax law, when someone dies, a CGT event is generally taken to occur just before their death, and the deceased’s date of death tax return may need to account for any capital gain or loss on assets that didn’t pass to a beneficiary or the LPR in the usual way. Separately, when a beneficiary later inherits and eventually sells the property, their own CGT position often depends on the property’s value at the date of death — more on this below.

The Legal Weight Behind an Executor’s Valuation Decision

Executors hold what’s known as a fiduciary duty — a legal obligation to act in the best interests of the estate and its beneficiaries, not to favour any one party, and to keep proper records of decisions made along the way. Valuing and managing estate property sits squarely within that duty.

Australian courts have taken this seriously. In the long-standing case of Booth v Public Trustee, an executor sold an estate property without first obtaining an independent valuation. When the sale price was challenged as being below market value, the court found the executor had breached their duty, and the sale was set aside. The case remains a useful reminder that “I thought it seemed about right” isn’t a substitute for documented, independent valuation evidence — whether a property is being sold, retained, or transferred to a beneficiary.

Common Errors Executors Make With Property Valuations

Most executors aren’t trying to cut corners — they’re simply unfamiliar with the process and under pressure to wind up the estate. The most frequent mistakes include:

• Using a real estate agent’s appraisal instead of a formal valuation. An agent’s appraisal is a useful guide for setting a sale price, but it isn’t usually prepared to the same evidentiary standard, and for a contested estate or an ATO query, it may not carry the same weight as a report from a suitably qualified, independent valuer.
• Valuing the property “as at today” rather than the date of death. This is the single most common technical error, and it can materially skew both the estate inventory and any later CGT calculation.
• Relying on the council rates notice or land tax valuation. These figures are set for rating and taxing purposes, use different methodology, and are frequently well below (or above) actual market value.
• Leaving it too long. The longer an executor waits, the harder it becomes to reconstruct historical evidence, and the greater the risk that beneficiaries start asking why nothing has moved.
• Not keeping the report. A valuation that isn’t retained with the estate records is of little use if the ATO asks a question two years later, or if a beneficiary disputes how the estate was divided.

How a Retrospective Valuation Is Actually Prepared

Because the valuer wasn’t standing in the property on the date in question, a retrospective valuation relies on a mix of historical data and, where needed, current inspection. In practice, this generally means:

• Reviewing historical comparable sales from around the relevant date, in the same suburb or a genuinely comparable area.
• Considering the property’s features and condition as they existed at that date, rather than today — if the property has since been renovated, extended, or subdivided, the valuer needs to account for what has changed since.
• Cross-referencing historical property records, previous valuations (if any exist), and market data specific to that period, since general market movements can differ significantly between suburbs.
• Preparing a written report that documents the methodology, the evidence relied on, and the valuer’s conclusion — the kind of documentation that holds up if the ATO or a court later asks how the figure was reached.

A valuation prepared to a recognised professional standard, by a suitably qualified and independent valuer, gives the executor something a rough estimate never can: a defensible position if anyone ever asks how the figure was calculated.

Retrospective Valuations and CGT for Beneficiaries

This is where things often get confusing for executors, and it’s worth understanding the basics even though the specifics should always be checked with an accountant or tax agent.

Scenario	What generally happens to the cost base	Is a date-of-death valuation needed?
Property acquired by the deceased before 20 September 1985	Resets to the market value at the date of death	Yes — this is essentially the only way to establish a defensible cost base
Property acquired on or after 20 September 1985, held as an investment	Generally carries over the deceased’s original cost base (purchase price plus eligible costs)	Not always required to calculate CGT, but still worth having for the estate inventory and to avoid later disputes
Property that was the deceased’s main residence, sold or transferred within the usual timeframes	May qualify for a full or partial main residence CGT exemption	Often still useful for probate purposes, even where CGT ultimately doesn’t apply

The rules around the main residence exemption for inherited property, and around post-1985 assets more generally, have a number of conditions attached, so this table is a starting point rather than the full picture. An accountant or tax agent can confirm exactly how it applies to a particular estate — but they’ll need an accurate date-of-death value to work with, which is where a retrospective valuation comes in.

When Executors Should Organise the Valuation

There’s no strict legal deadline for obtaining a retrospective valuation, but there are good practical reasons not to leave it too long:

• Historical sales evidence becomes harder to reconstruct as more time passes.
• Beneficiaries are entitled to ask what the estate is worth, and vague answers tend to erode trust.
• If probate is being applied for, the Court generally expects an inventory with values attached.
• The deceased’s date of death tax return, and any subsequent estate tax return, may depend on it.

As a general rule, organising the valuation early in the administration process — around the same time as applying for probate — avoids most of the problems that come from leaving it until later.

Frequently Asked Questions

Can I just use a real estate agent’s appraisal instead of getting a formal valuation?

An agent’s appraisal can be a helpful starting point, but it’s generally based on current market conditions and isn’t prepared to the same independent, evidence-based standard as a formal valuation. For probate, CGT purposes, or any estate where a dispute is even remotely possible, a report from a suitably qualified, independent valuer is the safer option.

What date does the valuation actually need to be “as at”?

Almost always the date the person died, not the date probate is granted or the date the valuer is instructed. This is the date used for both the deceased’s tax return and the beneficiaries’ future CGT calculations.

How far back can a retrospective valuation go?

Many valuers can prepare a valuation for a date well in the past, sometimes decades. The further back the date, the more the valuer has to rely on historical sales records rather than direct comparables, so it’s worth discussing the available evidence for the specific date and location before commissioning the report.

Do I still need a valuation if the property is going to a beneficiary rather than being sold?

Yes. Even where a property is transferred rather than sold externally, its date-of-death value still matters for the estate inventory, for a fair split between beneficiaries, and for the beneficiary’s own CGT position when they eventually sell.

Who pays for the valuation?

The cost is typically treated as an estate administration expense and paid from the estate, rather than out of the executor’s own pocket.

What if I’ve already distributed the estate without getting one?

It’s still worth obtaining a retrospective valuation after the fact — the report can be backdated to the relevant date using historical evidence. It won’t undo any problems already caused by an inaccurate distribution, but it can help resolve a dispute, satisfy an ATO query, or correct the estate’s records. Speaking to the estate’s solicitor first is a sensible next step.

Conclusion

Executors are trusted to get a property’s value right, not guess at it. A retrospective valuation, prepared as at the date of death by a suitably qualified and independent valuer, gives an executor the defensible evidence needed for probate, tax obligations and a fair distribution — and it’s one of the simplest ways to avoid disputes, ATO queries, or personal liability down the track.
