Caveat on probate workflow

A caveat stops a grant being made ex parte while the caveator challenges validity — testamentary capacity, undue influence, execution, or entitlement. The rules are short and time-critical. Get a caveat wrong and it is removed; get the timing wrong on a warning and the caveat lapses.

In short

This is an 8-step workflow for lodging or responding to a caveat on probate or letters of administration under Part 78 of the Supreme Court Rules 1970 (NSW) and equivalent state rules.

Time: 4 to 16 weeks from caveat through warning to resolution or summons.
Audience: Australian wills and estates lawyers acting for a person challenging or defending a grant of probate or letters of administration.

8 steps

The workflow

1

Assess grounds for caveat

Assess the grounds — testamentary capacity, knowledge and approval, undue influence, fraud, revocation, improper execution, or entitlement dispute — against the available evidence.

Tools: Quillio
Succession Act 2006 (NSW) s 5
2

File caveat with Probate Registry

File a caveat in the approved form with the NSW Supreme Court Probate Registry, including the address for service. The caveat lasts six months unless renewed or removed.

Tools: NSW Online Registry
Supreme Court Rules 1970 (NSW) r 78.69
3

Notify the proposed executor or administrator

Notify the proposed executor or administrator of the caveat. Open a privileged communication channel on evidence and grounds while preserving without prejudice settlement options.

Tools: Quillio
4

Respond to a warning

If the applicant for the grant serves a warning, the caveator must enter an appearance within the prescribed time (usually 8 days in NSW) stating the grounds. Missing the time limit lapses the caveat.

Tools: Quillio
Supreme Court Rules 1970 (NSW) r 78.72
5

Prepare the substantive evidence

Prepare affidavits addressing capacity (treating doctor, GP notes, specialist reports), knowledge and approval (solicitor's file, attestation), and any undue influence factual matrix.

Tools: Quillio
Banks v Goodfellow (1870) LR 5 QB 549
6

Negotiate or mediate

Most probate caveats settle with agreed orders — consent to grant with an agreed distribution, or withdrawal of caveat on compromise. Mediate through the Supreme Court mediation programme where appropriate.

Tools: Quillio
7

Prepare summons and probate suit

If unresolved, prepare the probate suit — summons for solemn form grant, affidavits, and interrogatories. Address standing, capacity, and alternative claims (Chapter 3 family provision) if relevant.

Tools: Quillio
Succession Act 2006 (NSW) Ch 3
8

Attend hearing and manage grant outcome

Attend hearing in the Supreme Court Equity (Probate) List. On outcome, implement — grant in solemn form, refusal, or limited grant pending trial of a discrete issue.

Tools: Quillio
Outcome

What you will have at the end

Either a negotiated resolution with agreed grant and distribution, or a Supreme Court determination on validity, entitlement, or the proper form of grant.

Common issues

  • Caveat lodged without a reasonable basis, inviting costs consequences
  • Appearance to a warning missed, lapsing the caveat
  • Family provision claim confused with a validity challenge
  • Insufficient medical evidence to ground a capacity challenge
  • Solicitor's file not requested under Grey v Grey principles
