What happened

In financial proceedings arising from the parties' marriage (married 1988, separated 2013), the husband issued a subpoena on 22 May 2019 to the wife's mother (the objector), who also appears in the proceedings in her own right and as executor of her late husband's estate, seeking extensive financial records dating back to 2005 (bank and credit card statements, tax returns and assessments, instalment activity statements, superannuation member statements, and records of B Pty Ltd) (see Reasons paras 1 and 8). The objector filed a Notice of Objection on 4 June 2019. A registrar, after considering written submissions, upheld the objection on 3 December 2019 (para 3). The husband applied for review of that registrar decision. Rees J heard the review de novo in Chambers (paras 4–6), treated the registrar’s absence of reasons as irrelevant on review, and upheld the objection (final operative order: "The Notice of Objection filed 4 June 2019 is upheld"). The Court’s reasoning focused on whether the subpoena had a genuine forensic purpose and whether it was "on the cards" that the documents would materially assist the husband’s case.

Why the court decided this way

The Court applied the settled test for subpoenas: a subpoena must have a legitimate forensic purpose and must call for documents that appear relevant in the sense of throwing light on issues in the principal proceedings; it must be "on the cards" that the documents sought will materially assist the party issuing the subpoena (the Court explicitly adopts the summary in Darley & Darley, and the authorities discussed therein) (Reasons, THE LAW). Rees J distilled the facts before the Court and asked whether the materials sought by the subpoena had that necessary forensic nexus to the husband's asserted case.

Two principal strands informed the Court's conclusion:

Lack of demonstrated relevance beyond already-produced materials. The objector had produced exhibits (some 408 pages) evidencing particular transactions said to be advances or payments (para 7). Rees J observed that, apart from those transactions and the conceded school fees, nothing in the husband's submissions explained why the objector's broader financial affairs (or B Pty Ltd's records) would add materially to his case (para 9). If the husband’s contention was that the objector’s finances constituted a financial resource of the wife, the Court found no material on the record to support that assertion (para 10).
The test of "fishing" and oppression. The Court reiterated that subpoenas cannot be used as a fishing expedition, and that oppression is a relevant consideration where great numbers of documents are sought without demonstrated sufficient relevance (drawing on the authorities cited in Darley & Darley and Wigney J’s judgments). On the basis of the material before the Court, Rees J concluded it was not "on the cards" that the broad records would materially assist the husband’s case, including on the assumption (for purposes of that part of the reasoning) that B Pty Ltd might be the objector's alter ego (paras 12, 15). Given that the husband had not demonstrated a sufficient forensic purpose for the broad temporal scope and categories sought, the objection was upheld (final operative paragraph).

The Court also clarified procedural and evidential expectations going forward: if the husband later obtains evidence linking the objector’s finances to the wife’s resources, he may issue a more focused subpoena, but first the objector should be required to file a financial statement before further subpoenas are considered (para 11).

On confidentiality, Rees J held that confidential or sensitive nature of financial documents is not in itself a proper basis for objection if those documents could otherwise be shown to be relevant and likely to assist, confidentiality should be addressed by protective orders restricting inspection rather than by refusal to produce (para 5).

Before and after state of the law

Before this decision, the law governing subpoenas in Australian civil and family proceedings was well established: subpoenas must have a genuine forensic purpose, be targeted to relevant documents, and must not be used for fishing expeditions or to oppress. Rees J expressly followed and applied that jurisprudence (citing Darley & Darley and authorities quoted therein) (THE LAW).

This decision applies those established principles in a family law context involving third-party financial records. It reinforces specific practical requirements:

A requesting party must articulate how broad categories of third-party financial records would materially assist the case, beyond isolated admitted transactions.
Confidentiality alone is insufficient to sustain an objection; courts should use protective measures to manage sensitivity.
Where some relevant transactional documents have already been produced by the objector, a broad secondary sweep of all records will not be granted absent evidence explaining incremental utility.
The Court signals a gatekeeping step: require a third-party to file a financial statement before permitting further intrusive subpoenas to inspect their entire financial affairs.

Thus, the decision is consistent with earlier authorities and clarifies procedural expectations in family law litigation where subpoenas are sought of third parties alleged to have provided financial assistance or to be the repository of resources.

Key passages with plain-English translation

"An objection was lodged ... On 3 December 2019 ... a registrar upheld the objection. No reasons were given." (para 3)
- Plain English: A registrar already refused to force the mother's production of documents; the court reviewing that decision treats the matter afresh even though no reasons were provided by the registrar.
"A subpoena must be issued for a genuine forensic purpose ... it must be 'on the cards' that the documents sought will materially assist." (THE LAW, after citing Darley & Darley)
- Plain English: You cannot subpoena someone just to see if information exists; there has to be a good reason that the documents will help prove something important in the case.
"If it is 'on the cards' that the documents could assist the husband's case, the fact that they might relate to confidential financial information is not a basis for objection ... the fact that they might relate to confidential financial information is not a basis for objection although it may be a basis for orders relating to disclosure or restricting the class of people who may inspect them." (para 5)
- Plain English: Sensitive bank records do not automatically avoid disclosure. If they are relevant, the court can limit who sees them rather than refusing to make them available.
"Nothing in the submissions on behalf of the husband explains why the financial affairs of the objector, other than those transactions ... could assist his case." (para 9)
- Plain English: The husband did not show how the mother's overall finances (beyond the specific payments already identified) would help his argument.
"I do not accept ... the submission that the objector's finances constitute a financial resource of the wife." (para 10)
- Plain English: The judge was not persuaded that the wife's mother’s money should be treated as the wife's resources for the purposes of the family law proceedings.
"If ... the husband is able to provide evidence ... then he can seek to issue a subpoena ... it would be appropriate, firstly, to require that the objector file a financial statement before any consideration is given to the issue of a further subpoena to her." (para 11)
- Plain English: If the husband later gets better evidence showing the mother's finances matter, he may ask again for documents, but first the mother should be asked to disclose her finances formally.
"The objection is upheld." (final operative line)
- Plain English: The mother's objection succeeds; she does not have to produce the additional documents sought by the subpoena.

What fact patterns trigger this precedent

This decision is most directly triggered in family law and related civil proceedings where:

A party subpoenas a third party (often a family member) for extensive financial records going back many years, asserting those records show financial assistance or hidden resources relevant to property or maintenance claims.
The subpoena seeks broad categories of documents (complete bank statements, tax records, company records) rather than narrowly-targeted transactional evidence.
The objector has already produced some transactional evidence or there is a known set of relevant transfers or payments (eg school fees, specific loans), and the subpoena attempts to expand to the objector’s entire financial affairs without the requesting party showing why the additional materials are likely to be necessary.
The requesting party has not produced evidential foundation connecting the third-party’s broader finances to the litigant’s financial resources (ie the 'financial resource' argument is asserted but not supported by evidence).
The subpoena could be seen as oppressive given its scope and temporal range.

In such fact patterns this judgment supports upholding objections unless the requesting party can show how the broader materials are likely to materially assist their case.

How later courts have treated it

(As at the date of this judgment submission, direct subsequent treatment may be limited; the decision follows established subpoena jurisprudence and cites Darley & Darley. Practitioners should watch for subsequent family court or appellate decisions that apply the same gatekeeping approach: requiring evidentiary foundation for broad third-party subpoenas, treating confidentiality as manageable by protective orders, and insisting on narrow, targeted requests tied to pleaded or evidenced contentions.)

This judgment will be cited as an example in family law practice as a practical enforcement of the "on the cards" test within family proceedings and as justification for requiring preconditions (such as a third party’s financial statement) before allowing intrusive discovery of third-party finances.

Still-open questions

Threshold for 'on the cards': The judgment requires that documents be 'on the cards' to materially assist, but practical guidance on the quantum and type of evidence sufficient to meet that threshold in different family law contexts remains fact-specific. How much preliminary evidence must a party produce to justify broad subpoenas will continue to be litigated.
Alter ego and corporate records: Rees J proceeded on an assumption for argument that B Pty Ltd might be the objector's alter ego but refused production on the facts. Future cases will need to clarify the evidential steps to pierce the corporate veil for subpoena purposes in family disputes, especially where small closely-held family companies hold property.
Use of protective orders versus refusal: The judgment emphasises that confidentiality is not a ground for refusal, but courts will have to balance the scope and form of protective orders in complex family disputes where sensitive non-party financial information is sought.
Procedure for subsequent subpoenas: Rees J proposed requiring a financial statement before further subpoenas are considered. The detailed mechanics of that process, timing, content, and consequences for refusal to file a financial statement, will require refinement in later decisions or practice directions.
Interaction with family law disclosure regimes: How this subpoena jurisprudence interacts with the obligations of parties under family law financial disclosure rules may create nuances, especially where third-party records arguably reveal a party’s interests or resources indirectly.

Practitioners should therefore treat this decision as a clear invocation of established subpoena principles in family law, and structure applications for third-party documents by providing focused evidential material demonstrating the forensic utility of the records sought, and be prepared to propose protective orders to manage sensitivity rather than rely on confidentiality as a shield to disclosure.

Ms A Pratten as Executor of the Estate of the Late Mr Pratten

[11]

On 22 May 2019 a subpoena was issued by the husband in financial proceedings to the wife's mother ("the objector") who is also an applicant in the proceedings, both in her own right and in her capacity as executor of the estate of the wife's late father.
The parties to the proceedings are:
- The applicant wife ("the wife");
- The first respondent husband ("the husband");
- The wife's mother ("the objector");
- The wife's mother as Executor of the Estate of the Late Mr Pratten; and
- The husband's mother, Ms McFarlane.
An objection was lodged to production on 4 June 2019. On 3 December 2019, after considering written submissions, a registrar upheld the objection. No reasons were given.
The husband now seeks to review the decision of the registrar. That application proceeds by way of hearing de novo. The fact that no reasons were given by the registrar is irrelevant.
Directions were made for the parties to file written submissions and it was agreed that the review would be dealt with in Chambers without the need for any further appearance in Court.
No submissions were filed on behalf of the husband pursuant to the directions but I have assumed that he relies on the submissions made to the registrar.
Submissions have been received from the objector and an affidavit from the wife.
The subpoena, relevantly, sought production by the objector of:
1. Copies of bank account and credit card statements from 2005 to date.
2. Tax returns and notices of assessment from 2005 to 2018.
3. Copies of tax refund statements from 2005 to date.
4. Copies of instalment activity statements for the objector and a company, B Pty Ltd, from 2005 to date.
5. Copies of documents relating to two specified bank accounts "for the period".
6. Copies of documents relating to payments to the objector by B Pty Ltd from 1 January 2010 to date.
7. Copies of member statements for any superannuation fund of which the objector is a member from 30 June 2010 to date.
8. Copies of bank account and credit card statements held by B Pty Ltd from 1 July 2005 to date.

[12]

In order to place the objection in context it is necessary to have some understanding of the ambit of the dispute.
The husband and the wife married in 1988 and separated in 2013.
They lived in a property owned by the wife's father until 1995 and then moved to a property at Suburb X owned by Mr C, the husband's uncle and the husband's mother, Ms McPherson.
In late 1995, Mr C sold his interest in the Suburb X property to B Pty Ltd. Mr Pratten was the wife's late father and the late husband of the objector. He died in October 2000 and left his shares in B Pty Ltd to the objector.
In 2005, B Pty Ltd transferred its half share of the Suburb X property to the wife.
The wife and the objector assert that Ms McPherson holds her half share of Suburb X on trust for the husband. Both the husband and Ms McPherson dispute that assertion.
The wife asserts that her parents provided the husband and the wife with significant loans during her father's lifetime and that, after her father's death, the objector has continued to lend her, or the husband and the wife, money. The objector says that a total of $517,968 was provided to the wife or to the husband and the wife, commencing in 2007 and that a further amount of $529,573 was paid by the objector and her late husband for school fees for the children of the marriage, commencing in 2000.

[13]

The wife, relevantly, seeks a declaration that the husband is the beneficial owner of half of Suburb X and that he be required to discharge the mortgage and transfer half of Suburb X to the wife unencumbered.
The objector seeks a declaration that Ms McPherson holds her interest in Suburb X on trust for the husband.
The husband and Ms McPherson seek orders dismissing the wife's and the objector's applications.

In Darley & Darley [2020] FamCAFC 4, Kent J, siting as a judge of appeal, summarised the law in relation to this issue:

[15]

It is well settled by the authority that a subpoena must be issued for a genuine forensic purpose and must identify what appear to be relevant documents. In Gloucester Shire Council v Fitch Ratings, Inc [2016] FCA 587 Wigney J observed the following at [22]:

[16]

The law concerning subpoenas is one of those areas of law where metaphors abound. The test for whether a subpoena has a legitimate forensic purpose has been put in terms of whether the material caught by the subpoena appears to have relevance in the sense of "throw[ing] light" on at least some of the issues in the principal proceedings: Cosco Holdings Pty Ltd v Commissioner of Taxation [1997] FCA 1504; (1997) 37 ATR 432 at 439-440. It has also been said that it must be "on the cards" that the documents sought will materially assist the party at whose request the subpoena has been issued: Alister v The Queen [1984] HCA 85; (1984) 154 CLR 404 at 414; Tamwood Limited (ACN 010 954 499) v Habitare Developments Pty Ltd (ACN 122 935 497) [2009] FCA 364 at [13], [35]-[38]. Slightly more prosaic statements of the test include that the documents must have some "apparent" or "adjectival" relevance, or would be reasonably likely to add, in the end, in some way or another, to the relevant evidence in the case: Spencer Motors Pty Ltd v. LNC Industries Ltd [1982] 2 NSWLR 921 at 927-928 G-A; National Employers' Mutual General Association Ltd v Waind [1978] 1 NSWLR 372 at 385 D-F; Trade Practices Commission v Arnotts Ltd (No 2) [1989] FCA 248; at 103; at .

[17]

A subpoena also cannot be used for the purposes of "fishing" or conducting a "fishing expedition". A finding of "fishing" amounts to a finding that the subpoena has no legitimate forensic purpose because the documents are sought to discover if the issuing party has a case, not to support a case that has already been articulated: Commissioner for Railways v Small [1938] NSWStRp 29; (1938) 38 SR (NSW) 564 at 575. A finding of "fishing" also appears to involve a question of oppression. A subpoena will be more readily set aside if great numbers of documents are required to be produced in circumstances where it cannot be demonstrated that they are likely to be sufficiently relevant: Dorajay at [34].

[18]

The Notice of Objection sets out the basis on which objection is taken to each paragraph of the subpoena.
In relation to the whole of the subpoena, the objector claims that the subpoena is oppressive and an abuse of process in that it seeks documents from 2005 onwards.
I do not accept that contention. It is asserted by the objector that the interest of B Pty Ltd in the Suburb X property was transferred to the wife in 2005. Requiring the production of documents from that time onwards is not, of itself, oppressive if there is some legitimate purpose for the documents.
The next objection relates to Paragraphs 2, 3, 4, 5, 6, 7 and 8 and is in two parts. The first is that the subpoena calls for documents which are sensitive and contain confidential information in relation to the objector's personal finances.
That is not a proper basis for objection. If it is "on the cards" that the documents could assist the husband's case, the fact that they might relate to confidential financial information is not a basis for objection although it may be a basis for orders relating to disclosure or restricting the class of people who may inspect them.
The second part of that objection is that the documents sought are not relevant to the proceedings.
It is difficult to see how the objector's financial affairs are relevant to the dispute between the husband and the wife. On behalf of the objector it is submitted that the husband has conceded that the wife's parents paid the school fees for the children. If it is the case that the documents are said to be relevant to the assertion of other financial assistance to the husband and the wife from 2007 onwards, then it is submitted that the objector has already provided, in the form of documents exhibited to her affidavit sworn 12 December 2018, bank statements and bank cheques evidencing the money advanced. The objector makes reference to some 408 pages of documents which have been provided.
Some of those documents have been redacted so that transactions referable to matters other than money advanced to the husband and the wife are not able to be read.
Nothing in the submissions on behalf of the husband explains why the financial affairs of the objector, other than those transactions which relate to money advanced to the husband and the wife, could assist his case.
