Subpoenas and third-party disclosure

The first subpoena I saw up close wasn't mine. A friend in West End rang me on a Sunday night and said, in a voice I had not heard him use before, "they've subpoenaed my GP." Then a long pause. "And my accountant. And the CBA. And my therapist. They want fifteen years of psychology notes." I sat on his back step with a beer that neither of us drank and watched him hold his phone at arm's length like it was a wasp.

His matter had been, until that week, a soft and slow consent-orders negotiation. The subpoenas changed the temperature in the room and they never changed back.

This isn't legal advice. It's a description of a tool from the receiving end.

What a subpoena is, mechanically

A subpoena is a court order, issued at the request of a party in a proceeding, requiring a third party to do one or both of two things. Produce documents, or attend court to give evidence. In family law matters in Australia, the subpoena is governed by the Federal Circuit and Family Court of Australia (Family Law) Rules 2021, Part 6.5, and is issued through the Commonwealth Courts Portal.

The third party can be almost anyone with relevant material. Banks. Accountants. Employers. Superannuation funds. Australian Taxation Office. Centrelink. Schools. Medical specialists. Treating psychologists and psychiatrists. The Department of Children, Youth Justice and Multicultural Affairs (in Queensland; equivalents in other states). Telcos for call records. Airlines for travel manifests. The Land Titles Office. Strata managers. Even your dating app, if its records are pertinent.

The party requesting the subpoena pays a fee (around $55 per subpoena at filing, plus conduct money to the recipient, typically $25 to $250 depending on the burden of compliance) and serves it on the third party. The third party has a defined window, usually around 14 days, to comply or to object.

The recipient is not on trial. They are not a party. They are simply the holder of records the court has decided are relevant.

What they can ask for

Almost anything that is potentially relevant to an issue in the proceeding. The "potentially relevant" test is wider than people expect.

In a property matter, expect requests for:

• Bank statements, credit card statements, loan records, often six years deep.
• Accountant working papers, draft tax returns, business management accounts, share register entries.
• Employer records of salary, bonuses, share option grants, salary sacrifice arrangements.
• Superannuation fund member statements, including SMSFs and historical balances.
• ATO records via the Tax Office's standard family law subpoena response.
• Settlement statements from any property sale, refinance documents, mortgage discharge papers.

In a parenting matter, expect requests for:

• Treating-doctor records (GP, paediatrician, allied health) for the children and sometimes the parents.
• School enrolment records, attendance records, incident reports, communications with teachers.
• Police records of any callouts to the home.
• Department of Child Safety (or state equivalent) records.
• Drug and alcohol testing results from any treatment provider.
• Communications with daycare and after-school-care providers.

The requesting party doesn't get a fishing licence. The court can set aside a subpoena that is too broad ("any and all documents relating to") or that is a fishing expedition. But the bar for a properly framed subpoena is not high, and most subpoenas land.

Your right to object

You can object to a subpoena. The mechanism is a Notice of Objection filed with the court before the return date, with a supporting affidavit setting out the grounds.

Common grounds:

• Lack of relevance. The documents have no genuine connection to an issue in the proceeding.
• Oppression or breadth. The subpoena is so wide it would take weeks to comply with, and a narrower version would meet the legitimate need.
• Privilege. Legal professional privilege over communications with your own lawyers. Some limited statutory privileges (counselling communications under the Family Law Act, section 10D, are protected in specific circumstances).
• Confidentiality of third parties. Records that contain extensive material about other people not party to the proceeding.

Worth knowing. Therapeutic communications between a parent and a counsellor in a Family Dispute Resolution context are protected under section 10D of the Family Law Act. Notes from a private therapist outside that framework are not protected the same way. The protection many people assume exists is narrower than they think.

When you object, the court lists the matter for argument. The judge or registrar reads the affidavits, hears short submissions, and rules. Sometimes the subpoena is set aside. More often it is narrowed. Occasionally it stands as issued.

What it costs

Several layers of cost, all real.

• The third party's compliance cost. Banks and the ATO have standard fees ($30 to $300 per subpoena typically). Accountants, doctors, and psychologists charge professional rates ($300 to $2,500 depending on volume). The party who issued the subpoena pays this initially.
• Your legal cost in objecting. A solicitor's affidavit and short hearing is rarely under $2,500 to $5,000. A barrister's appearance to argue the objection lifts that materially.
• The relational cost. The accountant who has to spend a day pulling files. The therapist who feels their notes will be read by lawyers. The employer who now knows your marriage is in court. These are not legal costs and they are not nothing.
• The matter's cost. Once subpoenas are flying, the soft routes have shut. Mediation becomes harder. Consent orders become a longer conversation. The trajectory has shifted toward contested final hearing.

Body metaphor. A subpoena is the moment a quiet conversation moves into an X-ray room. Every soft tissue you had been talking around becomes visible at once, and the room is colder.

Why subpoenas are usually a sign

In my experience, and in the experience of every family lawyer I have asked, subpoenas correlate with one of three situations.

• Disclosure has been incomplete. One side believes the other is hiding assets, income, or behaviour, and the subpoena is the bypass. The presence of subpoenas is a comment on the trust level in the matter.
• The matter is heading to final hearing. Subpoenas are evidence-gathering for trial. Their issue is a tactical signal that settlement attempts have failed or been abandoned.
• A specific allegation needs proof. A drug allegation needs the testing records. A family violence allegation needs the police callouts. A hidden-business allegation needs the bank statements and the accountant's working papers.

The first situation is preventable. The second and third are sometimes appropriate uses of the tool.

When I see a matter where one side is firing off ten subpoenas in week six, my read is almost always that disclosure broke down somewhere upstream. The other side asked for documents. They got partial documents. They asked again. They got delays. They issued the subpoenas because they had run out of polite options.

The simple alternative

The cheapest defence against ever being on the receiving end of a barrage of subpoenas is complete voluntary disclosure, given early and updated regularly. The duty of disclosure already requires it. The subpoena is what happens when the duty is not met.

A practical move. When your solicitor sends the standard disclosure request to the other side, send your own pack proactively at the same time. Not "here's what you asked for" but "here's everything material I hold." Date-stamped. Indexed. With a covering letter that says "I have included material you have not requested but which is relevant. If anything is missing, ask, and I will provide it."

That single move does several things at once. It makes you credible to the other side's lawyer (who will tell them you're being straight). It makes their case for subpoenas harder to mount in front of a judge. It anchors your voice in the matter as the party doing the right thing. And it gives you cover if they later issue subpoenas anyway, because the court can see you tried.

ENOUGH about the worst-case scenario

If you have already received a subpoena directed at you (rare, since subpoenas usually go to third parties not the parties themselves) or if you have been notified that a subpoena has been issued to a third party that holds your records, the moves are concrete.

• Read it carefully. Note the return date. Note the documents requested. Note who issued it.
• Tell your solicitor immediately. They will assess whether to object, whether to inspect the documents before they go to the other side, and whether the matter has shifted enough to need a different strategy.
• Inspect what's produced. When third-party documents are produced to the court, both parties can inspect them in the registry before they become evidence. This is the moment to know what's in your own bank records, employer file, or medical history, often before your former partner sees it.
• Don't contact the third party directly to ask them not to comply. That can be witness interference. Anything you want to say goes through your lawyer.

The friend in West End settled his matter, eventually, by consent. The therapist's notes were narrowed (they ended up producing six pages, not the whole file) and the bank produced what it always produces. The temperature in the room never warmed back up to where it had been before the subpoenas, but the matter ended. It cost more, in money and relationship, than it would have if disclosure had been complete from week one.

Disclose first. Subpoena last. Settle in between.
