Probate Caveats in South Australia: When to Lodge One and What Happens Next

A probate caveat is a formal legal instrument that stops the Supreme Court of South Australia from issuing a Grant of Probate or Letters of Administration. It's a serious step with serious consequences — both for the estate administration and potentially for the person who lodges it without sufficient grounds.

Used correctly, a caveat is a necessary tool to protect against a fraudulent or invalid grant. Used incorrectly — as a stalling tactic or a substitute for proper legal advice — it can result in significant cost orders against the person who lodged it.

What a Probate Caveat Does

When a caveat is lodged via the CourtSA portal, the Probate Registry is legally prohibited from issuing any grant relating to that estate. The grant process is frozen for up to six months from the date of lodgement.

During that window, the person who lodged the caveat (the caveator) must either:

• Successfully negotiate a resolution with the applying executor or administrator, or
• Commence formal court proceedings challenging the grant application

If neither happens within six months, the caveat automatically lapses and the grant process resumes.

When a Caveat Is Appropriate

Caveats are appropriate where there is a genuine, legally grounded reason to believe a grant should not be issued. The most common legitimate grounds include:

Lack of testamentary capacity. If the deceased appeared to lack mental capacity when they signed the will — for example, due to advanced dementia, a stroke, or other cognitive impairment — there may be grounds to challenge whether the will was valid. A caveat gives time to obtain medical records and legal advice before the grant is issued.

Undue influence or fraud. If a family member or carer pressured or manipulated the deceased into making or altering their will, the resulting document may be challengeable. Again, a caveat creates space to investigate.

Suspicious circumstances. Where the will was made in unusual circumstances — prepared very close to death, with unexpected beneficiaries, or with significant changes from earlier documents — a caveat may be warranted while inquiries are made.

A later will exists. If you have evidence that a more recent, properly executed will exists but hasn't been produced by the applying executor, a caveat prevents the older document from being probated.

When a Caveat Is Not Appropriate

A caveat is explicitly not a tool for:

• Buying time to prepare a family provision claim. Family provision claims are a separate legal action under the Succession Act 2023 and do not require — or benefit from — a probate caveat.
• Expressing general dissatisfaction with the terms of the will. Unhappiness with an inheritance isn't grounds to stall the grant.
• Pressuring the executor into negotiations by using the caveat as a threat.

The Supreme Court has the power to order significant cost awards against caveators who lodge without proper grounds. If you lodge a caveat frivolously and it is successfully challenged, you may be personally required to pay the executor's legal costs of addressing it.

How to Lodge a Probate Caveat in South Australia

Since Chapter 25 of the Uniform Civil Rules 2020 took effect, caveats are lodged electronically through the CourtSA portal.

The filing fee is $44.25 to lodge a caveat, and $44.25 to withdraw one.

The lodgement process requires:

• A registered CourtSA account
• The name and date of death of the deceased
• The caveator's details and relationship to the estate
• A brief statement of the grounds for the caveat (though detailed particulars may come later in proceedings)

A caveat does not need to be served on the executor directly — the Probate Registry manages this administratively by blocking the grant.

What Happens After a Caveat Is Lodged

The CourtSA portal and the Probate Registry flag the estate as subject to a caveat. The applicant for the grant is notified and the application is frozen.

The caveator typically has two options:

Negotiate a resolution. In many cases, caveats lead to negotiated outcomes — the executor provides additional information, an independent solicitor reviews the will's execution, or family members reach an agreement without litigation. Many caveats are withdrawn within weeks once parties engage properly.

Commence court proceedings. If the dispute cannot be resolved, the caveator must file a court application challenging the grant. This converts the matter from non-contentious probate administration into contentious civil litigation. The matter will be heard before a Supreme Court judge, with full disclosure of documents, potential cross-examination, and significant legal costs on both sides.

A caveat that lapses after six months without proceedings being commenced is generally treated as abandoned, and the grant can proceed.

The Relationship with Family Provision Claims

Family provision claims under Sections 115–116 of the Succession Act 2023 allow eligible applicants to seek a court order for a greater share of the estate than the will provides. These are entirely separate proceedings from a caveat.

A caveat challenges whether the will is valid or whether probate should be granted. A family provision claim accepts the will is valid but argues the distribution it makes is inadequate.

Family provision claims are subject to strict time limits — typically six months from the date probate is granted. If you're considering a family provision claim, do not confuse it with a caveat. Consult a succession litigation solicitor promptly, as missing the family provision deadline can result in the claim being permanently barred.

Practical Advice

Before lodging a caveat, get legal advice. A caveat that lacks proper grounds will ultimately fail and may result in a costs order against you. A solicitor specialising in estate disputes can assess whether your concerns justify a caveat, and if so, advise on what evidence you'll need.

If you have genuine concerns about the validity of a will, act quickly. CourtSA applications move on their own timetable, and once a grant is issued, challenging it becomes significantly more complex and expensive.
