Probate vs Letters of Administration in NSW: Key Differences

Introduction

When someone dies in New South Wales, probate and letters of administration give a person legal authority to deal with the deceased person’s estate. The grant needed turns on whether the deceased left a valid will or died intestate.

Probate confirms the executor named in a will, while letters of administration allow the Supreme Court of NSW to appoint an administrator to distribute assets under intestacy rules. This article explains the key differences for people managing an estate in NSW.

Core Definitions of Probate & Letters of Administration

What is a Grant of Probate?

A grant of probate is a court order issued by the Supreme Court of NSW after proving that a deceased person’s Will is valid. The grant confirms that the executor named in the Will has authority to administer the estate.

The executor can use the grant of probate to:

• collect the deceased’s assets;
• pay debts; and
• distribute the estate according to the Will.

Banks and other organisations may require the grant before releasing funds or transferring assets.

What are Letters of Administration?

Letters of administration are issued when:

• a person dies intestate without a valid Will; or
• the executor named in a Will is unable or unwilling to act.

The Supreme Court of NSW appoints an administrator to administer the estate. The administrator performs a role similar to an executor, but must distribute the estate according to the rules of intestacy where there is no Will.

If a Will exists but the executor cannot act, the court may grant administration with the Will annexed.

Key Differences Between the Two Processes for People in NSW

The Requirement of a Valid Will

Probate requires a valid will; as explained above, the grant confirms the will and the executor’s authority to administer the estate under it.

Letters of administration are necessary without a valid will, including where:

• a person dies intestate; or
• the named executor cannot or will not act.

The Role of an Executor vs an Administrator

As covered above, a probate grant confirms the named executor’s authority to administer the estate, while letters of administration appoint an administrator by court order. 

The administrator performs a similar role but acts under a court appointment rather than because of an executor named in the will.

Administering an estate without a will can require more work to:

• establish the next of kin; and
• determine who may apply for a grant.

Adherence to the Will vs NSW Intestacy Laws

Probate allows the executor to follow the instructions in the will when administering and distributing the estate. The beneficiaries and each beneficiary’s share of the estate are determined by that document, subject to any separate court proceedings.

Letters of administration require the administrator to obey the rules of intestacy. Under the Succession Act 2006 (NSW) (‘Succession Act‘), those rules determine:

• which relatives inherit when a person dies intestate; and
• the order in which they receive the estate.

Supreme Court Costs & Expected Timeframes for Estate Administration

Expected Timeframes for a Grant of Probate & Letters

A grant of probate application in NSW often takes several weeks to a few months after lodging. The Supreme Court of NSW typically takes four to eight weeks to issue a grant once a complete application has been filed, although preparing the documents and asset information can add time.

Letters of administration may take longer, particularly where there are questions about who should be appointed as administrator. Delays may also arise from:

• incomplete paperwork;
• disputes about the will;
• disagreements between family members; or
• difficulty identifying the next of kin.

The wider estate administration process commonly takes six to twelve months.

Supreme Court Filing Fees Based on Estate Value

The Supreme Court of NSW charges a filing fee based on the gross value of the NSW assets in the estate. For the 2025–2026 financial year, the fees are:

• Less than $100,000: $0
• $100,000 to less than $250,000: $914
• $250,000 to less than $500,000: $1,243
• $500,000 to less than $1 million: $1,902
• $1 million to less than $2 million: $2,536
• $2 million to less than $5 million: $4,227
• $5 million and above: $7,051

These filing fees are separate from any legal fees for preparing an application for probate or letters of administration.

The Six Month Deadline to Apply

An application for a grant of probate or letters of administration should be made within six months of the deceased person’s death, unless there is a reasonable explanation for the delay. The six-month period is not a statement that estate administration must be completed within that time.

The executor or next of kin should gather the following before applying:

• the death certificate;
• the will, where one exists; and
• a list of the assets of the estate.

Where the six-month period has passed, the applicant should explain the delay when applying for probate or letters of administration.

Priority Rules for Letters of Administration

The Hierarchy of Next of Kin

When a person dies intestate and no executor is available, the Supreme Court of NSW applies a priority order when deciding who may administer the estate. Under Section 63 of the Probate and Administration Act 1898 (NSW) (‘Probate and Administration Act‘), the court may grant letters of administration to:

• the deceased person’s spouse;
• one or more of the next of kin; or
• the spouse together with one or more of the next of kin.

The proposed administrator must be an adult and considered suitable to be trusted with the estate. A close family member, such as a spouse or child of the deceased, will often be considered before other applicants. The administrator can then administer the estate and distribute the assets according to the rules of intestacy.

When a Creditor Can Apply for Administration

A creditor can apply for letters of administration when the spouse or next of kin:

• do not apply;
• do not comply with a court direction; or
• are not suitable to administer the estate.

Under Section 63 of the Probate and Administration Act 1898 (NSW) (‘Probate and Administration Act‘), the court may grant administration to another person, including a creditor, if it considers that person fit.

The court is cautious because a creditor may face a conflict between recovering a debt and protecting the beneficiary’s interests. A creditor’s application is weaker than an application by a person with a closer interest in the estate.

The court may impose conditions, including restrictions on distribution, to protect the estate and its beneficiaries.

Real NSW Case Studies on Estate Administration

The Estate of Dean John Edmunds & Creditor Applications

In Re the Estate of Dean John Edmunds [2025] NSWSC 223 (‘the Edmunds case’), the deceased died intestate, leaving four children as next of kin. The deceased’s mother applied for letters of administration as an unsecured creditor after the children did not apply. 

Under Sections 63 and 74 of the Probate and Administration Act, the Supreme Court of NSW granted administration to the mother, despite the usual priority given to a spouse or next of kin.

The court recognised potential conflicts between the mother’s interests as creditor and her duties as administrator. As a result, strict controls were imposed, including:

• The estate could not be distributed without the next of kin’s consent or the court’s approval.
• Regular updates had to be provided.
• Proposed payments or compromises required 21 days’ notice.

The Estate of Smith & Evidence That the Deceased Left No De Facto Spouse

In The Estate of Smith [2024] NSWSC 725 (‘the Smith case‘), the deceased died intestate without a spouse, children, parents or siblings. A niece applied for letters of administration, but the Registrar required evidence that the deceased had not left a domestic partner. 

Under part 78 Rule 20(2) of the Supreme Court Rules 1970 (NSW) (‘NSW Supreme Court Rules‘), the supporting affidavit needed to address that issue.

The niece provided evidence of enquiries with people and organisations connected to the deceased. After 18 months:

• No person claiming to be a de facto partner;
• No registered relationship
• No caveat had been lodged; and
• No family provision claim had been filed.

The Supreme Court of NSW accepted the evidence and ordered that the grant of letters of administration proceed.

Conclusion

Probate is tied to an effective Will and the person appointed in it, while letters of administration may be required when a person dies without a valid Will or an executor cannot act. That distinction affects who administers the estate, whether distribution follows the Will or NSW intestacy rules, the court process, and the information the Supreme Court of NSW may require.
