Deceased Estate and Probate Property Valuations in NSW: The Executor Guide

Being named executor of a loved one's estate comes with a long list of responsibilities, and figuring out what the property is actually worth is one of the more confusing ones. It's not as simple as checking a recent sale down the street or asking an agent for a rough figure. The NSW Supreme Court and the ATO both expect something more specific: an independent valuation that reflects the property's value on the date the person died, not today.

This guide walks through what a probate property valuation actually is, when you need one, what the court and ATO expect to see, and the mistakes that tend to trip executors up along the way.

What Is a Probate Property Valuation?

A probate property valuation, also called a deceased estate valuation, establishes the market value of a property as at the date of death. This "date of death" figure becomes the reference point for almost everything that follows: the probate application itself, any capital gains tax calculation beneficiaries will eventually face, and the fair division of the estate among multiple heirs.

It's a retrospective assessment, which makes it a genuinely different exercise from valuing a property today. A certified valuer needs to reconstruct what buyers were actually paying for comparable properties around that specific date, sometimes months or years in the past, using archived sales data and market conditions from that period.

How Is This Different From a Standard Appraisal?

A real estate agent's appraisal is designed to help set a listing price and reflects current market conditions. A probate valuation is a formal, evidence-based report prepared by a certified practising valuer, built specifically to withstand scrutiny from the court, the ATO, or beneficiaries who might later question the figure. The two documents are not interchangeable, even though they can look similar on the surface.

When Do You Need One as an Executor?

Most NSW estates that include real property will need a probate valuation at some point, whether or not the estate falls above the court's formal probate threshold. A few common triggers stand out.

If you're applying for a grant of probate through the Supreme Court, the value of estate assets, including any residential property valuation, forms part of what's disclosed in the application and factors into the court filing fee. Beyond the court process, a date-of-death valuation typically sets the capital gains tax cost base for whichever beneficiary eventually inherits the property, which matters enormously if that property is ever sold down the track. And where multiple beneficiaries are dividing an estate, an independent figure everyone can agree on tends to be the fastest way through what can otherwise turn into a lengthy dispute.

Joint Tenancy vs Tenants in Common

Not every property needs to go through probate at all. If the deceased owned the property as joint tenants, ownership usually passes automatically to the surviving owner, bypassing probate entirely. Where the property was held as tenants in common, though, the deceased's share forms part of the estate and does need a valuation. It's worth checking the title carefully, since the two arrangements are easy to confuse and lead to very different processes.

What the Supreme Court and ATO Actually Require

Here's the thing most executors don't realise until they're deep into the process: neither the court nor the ATO will accept just any figure. Both expect a valuation built on objective, supportable evidence, prepared by someone independent of the estate. A ballpark figure from a family friend in real estate, or even a well-intentioned online estimate, generally won't meet the bar.

What they're looking for is a documented methodology. That means comparable sales evidence from around the date of death, a clear explanation of how the valuer arrived at their figure, and the valuer's professional qualifications sitting behind the report. This isn't bureaucracy for its own sake. It protects the executor from personal liability if a beneficiary later challenges the distribution, and it gives the ATO confidence in the CGT cost base being claimed.

What Happens If a Valuation Is Challenged?

If a beneficiary disputes the figure used, or the ATO queries the CGT cost base years later when the property is sold, a well-documented independent valuation is what stands between the executor and a much longer, costlier argument. Weak or informal evidence leaves everyone exposed, including the executor personally, since executors carry legal responsibility for how the estate is administered.

The Probate Valuation Process, Step by Step

The process itself is fairly linear, though timeframes can shift depending on how straightforward the property and the estate are.

Complex estates, rural properties, or those with unusual title arrangements can take longer, so it's worth starting this process early rather than waiting until the court application is otherwise ready to go.

What Does a Probate Valuation Cost?

Costs vary depending on the property type, its location, and how complex the valuation is. A straightforward residential property in a well-documented market will generally cost less than a rural property, a commercial asset, or a property where sales data from the relevant historical date is harder to source. It's reasonable to ask for a quote upfront once you know the property's location and type, since this is an estate expense that's typically reimbursed once assets are available.

Common Mistakes Executors Make

A few patterns come up again and again with first-time executors, often because nobody explains the requirements clearly at the outset.

Using the property's current value instead of its date-of-death value is probably the most common one, particularly in a market that's moved since the person passed away. Relying on an agent's appraisal rather than a certified valuation is another, understandable given agents are often the first call people make, but it can create real problems down the line if the ATO or a beneficiary later questions the figure. And probate application volumes have risen across NSW in recent years, which means processing times are already under pressure. Waiting to organise a valuation until the last minute only adds to that delay.

Frequently Asked Questions About Probate Property Valuations

Do I need probate if the property was jointly owned? Generally no. Property held as joint tenants passes automatically to the surviving owner and bypasses probate. If it was held as tenants in common, the deceased's share does need to go through the process.

Can I use the property's current value instead of date of death? No. The court and the ATO both require the valuation to reflect market conditions as at the date of death, not today's value, even if that date was some time ago.

How long does a probate valuation take? A straightforward residential valuation is often completed within a week of the initial inspection, though this can extend for rural or commercial properties, or where comparable sales data is harder to source for the relevant date.

What if beneficiaries disagree with the valuation? An independent, well-documented valuation from a certified valuer is generally the fastest way to resolve disagreements, since it gives all parties a figure that isn't influenced by any one beneficiary's interest.

Do I need a valuation if the estate is below the probate threshold? Even where a formal grant of probate isn't required, a date-of-death valuation is often still needed to establish the CGT cost base for beneficiaries, so it's worth organising one regardless.

Can a real estate agent's appraisal be used for probate? It's not recommended. Agent appraisals aren't prepared to the same evidentiary standard as a certified valuer's report and may not be accepted by the court or hold up if the ATO later reviews the CGT position.
