Partial intestacy happens when a valid will exists but fails to dispose of all the estate. The gap gets filled by NSW’s intestacy rules under the Succession Act 2006, even while the rest of the will still governs everything it does cover. If you’re an executor or beneficiary facing this, your first move is to check the will’s residuary clause and work out whether a court grant is needed to deal with the undisposed portion.
TL;DR:
- Partial intestacy occurs when a valid will does not dispose of all estate assets, triggering NSW’s intestacy rules for the undisposed portion, regardless of the will’s validity.
- The undisposed estate is distributed according to statutory priority, with spouses or de facto partners first, followed by children, then more distant relatives, and unrelated parties receive nothing.
- A grant of letters of administration with the will annexed is often needed when assets like real property or bank accounts are caught by the intestacy, and it allows the administrator to manage both willed and intestate assets under one authority.
- Executors must identify all assets early, pay debts, publish creditor notices, and keep detailed records to navigate partial intestacy effectively and avoid personal liability.
- Drafting comprehensive, up-to-date wills with broad residuary clauses and substitute beneficiaries is the best way to prevent estate gaps, especially after significant life changes or asset additions.

What is partial intestacy under the Succession Act 2006?
Section 102 of the Succession Act 2006 (NSW) sets out the statutory basis: where someone leaves a valid will but that will doesn’t effectively dispose of all their property, the leftover portion is treated as intestate. It doesn’t matter whether the will is otherwise perfectly sound. A single failed gift, or a residuary clause that doesn’t cover everything, is enough to trigger the rule.
The practical effect is that NSW law treats the undisposed assets “as if” the deceased had no will at all, purely for the purpose of working out who gets them. Everything the will does properly deal with, specific gifts, named beneficiaries, and clear instructions, still stands. Only the gap gets the statutory treatment.
A few terms matter here. The residuary estate is whatever’s left in the estate after specific gifts, debts, and expenses are accounted for. The intestate estate is the portion (whole or partial) that falls outside the will’s effective operation. A spouse or de facto partner includes a person married to the deceased or in a de facto relationship for a continuous period, which affects who sit at the top of the priority order. The statutory legacy is a fixed initial sum a surviving spouse can be entitled to before the estate is split further, a figure that’s indexed and worth confirming at the time of administration rather than assuming it’s static.
Partial intestacy is more common than most people expect. It’s rarely the result of someone dying without a will. It’s usually the result of a will that hasn’t kept pace with the estate it’s meant to cover.
Who inherits the undisposed portion in NSW?
The undisposed assets follow the same statutory order of priority set out in NSW’s dying-without-a-will guidance, regardless of what the rest of the will says about the deceased’s wishes.
A surviving spouse or de facto partner is first in line, and where there’s only one spouse and no children from outside that relationship, that spouse typically takes the entire intestate portion. Where there are children from another relationship, the spouse still receives a statutory legacy plus household chattels, with the balance split between the spouse and those children under a formula set by the Act. If there’s no spouse, the children inherit directly, in equal shares. No children and no spouse pushes it further down the line: parents, then siblings, then more distant relatives such as grandparents, aunts, uncles, and cousins.
This is where the rigidity of intestacy law catches people out. Stepchildren, foster children who were never formally adopted, and in-laws generally have no automatic entitlement under this order, no matter how close the relationship was in life. If the deceased genuinely intended to provide for a stepchild but that intention only lived in the failed part of the will, the statutory order simply won’t recognise it. That’s often the exact scenario that ends up in a family provision claim.
When do you need letters of administration with the will annexed?
Not every partial intestacy needs a fresh court application. If the will already names an executor and that executor is applying to deal with assets the will does cover, ordinary probate still works. The complication arises with assets caught by the undisposed portion, particularly real property, solely held bank accounts, or a deceased’s share as tenants-in-common, where a formal grant is usually required before anyone can legally deal with the asset.
This is where a Grant of Letters of Administration with the Will Annexed comes in. The Supreme Court of NSW issues this specific type of grant when there’s a valid will (so straightforward letters of administration for a full intestacy don’t apply) but the will doesn’t fully appoint an executor or fully dispose of the estate, meaning plain probate doesn’t cover the gap either. The grant lets the administrator deal with both the willed assets and the intestate portion under one authority.
The application generally involves filing an application with supporting affidavits, the original will, a death certificate, and evidence of the estate’s assets and liabilities. Advertising the intention to apply is required before filing, giving interested parties a chance to raise objections. Turnaround varies with the registry’s workload and the completeness of the paperwork, but a well-prepared application with the right precedent forms and checklists moves considerably faster than one filed with gaps.
Executor duties, timing, and creditor notices: a practical checklist
An executor or administrator dealing with partial intestacy carries the same fiduciary obligations as anyone administering a full estate: act in good faith, keep estate funds and property separate from personal assets, and be ready to account for every decision made along the way.
Timing matters more than most executors realise. Legal Aid NSW’s distribution guidance recommends publishing a Notice of Intended Distribution, which opens a window for creditors to come forward, and generally holding off on final distribution to allow time for any claims against the estate. Neither step is strictly mandatory, but skipping them leaves an executor personally exposed if a creditor or claimant surfaces after assets have already been handed out.
A practical sequence looks like this:
- Identify every asset, including ones that sit outside the estate altogether, such as jointly held property and superannuation with a binding nomination.
- Determine which assets the will covers and which fall into the intestate portion.
- Pay outstanding debts and administration expenses before distributing anything.
- Apply for probate or letters of administration with the will annexed if the assets require it.
- Publish a Notice of Intended Distribution and observe the 30-day creditor window.
- Transfer or distribute assets according to the will and the statutory order, keeping full records of every transaction.
Cross-checking the will against bank records, super fund nominations, and land title searches early on saves enormous grief later, because it’s the fastest way to discover a partial intestacy exists before you’ve already started distributing.
Pro Tip: Keep a running file, even a simple folder, of every letter, valuation, and payment you make as executor. If a beneficiary or creditor later disputes how you handled the estate, contemporaneous records are worth far more than your memory of what happened eighteen months ago.
Why partial intestacy happens and how to draft around it
Most partial intestacy traces back to one of a handful of drafting gaps. The most common is a residuary clause that’s too narrow or simply missing, leaving assets acquired after the will was signed with nowhere to go. Close behind is a gift that fails, a named beneficiary who has died with no substitute nominated, or a condition attached to a gift that was never satisfied. Assets that pass outside the will entirely, superannuation death benefits paid under a binding nomination, or property held as joint tenants, can also shrink the effective estate in ways the will-maker never anticipated.
Law reform analysis on this exact problem points to one fix above the rest: a broad, well-drafted residuary clause with genuine catch-all wording, paired with substitute beneficiaries for every significant gift. That combination, according to the NSW Law Reform Commission, is the most reliable way to stop an estate falling through the gaps, though no drafting can guarantee against every possible failure.
Reviewing a will every three to five years, or immediately after a marriage, divorce, new child, or major asset purchase, catches most of these problems before they matter. During a review, check the residuary clause still covers everything you own, confirm your super fund’s binding nomination still matches your wishes, and update the estate plan if your asset structure has changed since the will was signed.
When it’s time to get legal advice on a partial intestacy
Some partial intestacy situations resolve themselves with a straightforward court application and no disagreement among the family. Others don’t. If you suspect you’ve been excluded from a distribution you reasonably expected to share in, if the family involves a blended structure with children from more than one relationship, if the will’s wording is genuinely ambiguous, or if an executor’s handling of the estate exposes you (or them) to a creditor dispute, it’s time to get advice rather than guess.
The available paths range from a negotiated agreement between beneficiaries, through mediation, to a formal family provision claim or contested probate proceedings where the estate’s administration itself is in dispute. Which path fits depends heavily on the specific facts, the size of the estate, and how entrenched the disagreement already is.
Legal advice often starts with a complimentary 30-minute consultation to assess your situation. Bring a copy of the will, the death certificate, any correspondence with the executor or other beneficiaries, and whatever financial records you have on the estate’s assets. That’s usually enough for an initial read on where you stand.
What the intestacy rules get wrong (and what executors should actually prioritise)
The intestacy rules exist to produce a predictable outcome when there’s no expressed wish to follow, and on that measure they work fine. The problem is that partial intestacy isn’t really “no expressed wish”. It’s a wish that got expressed badly, or an estate that outgrew the will drafted for it. Applying a rigid statutory formula to that situation produces results the will-maker almost certainly didn’t intend, and the people most likely to be shut out, stepchildren, long-term but informal dependants, aren’t abstract cases. They’re the exact relationships modern estates increasingly involve.
Conventional advice tends to focus on “get a will” and stop there. That’s not wrong, but it misses the more common failure point: wills that exist, were valid when signed, and simply weren’t revisited after life moved on. If you’re an executor facing a gap right now, don’t spend your energy trying to guess what the deceased “would have wanted”. Spend it establishing exactly which assets fall inside the will, which fall outside it, and which fall into the gap, because that groundwork determines every step that follows.

FAQ
What are the rules of intestacy in NSW?
NSW intestacy rules set a statutory order of priority, starting with a surviving spouse or de facto partner, then children, then parents, siblings and more distant relatives, and this order applies to any undisposed portion of an estate under partial intestacy just as it does to a full intestacy.
What is the two year rule for a deceased estate?
This generally refers to the window for a family provision claim, which under NSW law must usually be filed within twelve months of the date of death unless the court grants an extension, so if you’re considering a claim, get advice well before any deadline rather than relying on a general “two year” assumption.
Who is disqualified from inheriting under a will?
A person can lose their entitlement if they unlawfully killed the deceased, if a gift to them fails for a legal reason such as being a witness to the will in some circumstances, or if a divorce revokes a gift made to a former spouse, though the specific rule depends on the facts of each case.
What are the inheritance laws in New South Wales?
Inheritance in NSW is governed primarily by the Succession Act 2006, which covers valid will-making, the statutory intestacy order when there’s no will or a partial gap in one, and family provision claims for people left out of a will or an intestate distribution who believe they should have been provided for.
