Property settlements depend on both parties putting their full financial position on the table. When one party suspects the other is hiding money — a quiet account, an undeclared business income stream, cryptocurrency, gambling winnings — proving it can feel impossible. Bank statements only show the accounts you know about. This is where digital forensics can play a quiet but powerful role: modern financial life leaves digital traces, and those traces often survive on devices and in accounts long after the paperwork has been tidied up.

The duty of full and frank disclosure

Under the Family Law Act 1975 (Cth) and the court rules, parties to family law property proceedings owe each other a duty of full and frank financial disclosure. This is an ongoing obligation covering income, assets, liabilities, superannuation and financial resources — including interests held through companies, trusts and other structures.

The consequences of breaching that duty can be serious. Depending on the circumstances, courts may draw adverse inferences against a non-disclosing party, make cost orders, or in some cases set aside and reopen a settlement reached on false information. Deliberately concealing assets is a high-risk strategy — and one that increasingly fails, because digital footprints are hard to erase completely.

Digital traces of undisclosed assets

Almost every financial product today has an app, a login, an email trail or a browser history entry. Common digital indicators examined in property matters include:

Banking and finance apps

An undisclosed account often means an undisclosed banking app, or remnants of one, on a phone. Even after an app is deleted, artefacts such as notification records, cached data and account references can persist and may be identified through mobile phone forensics.

Cryptocurrency wallets and exchanges

Crypto is frequently assumed to be untraceable. In practice, exchange apps, wallet software, recovery-phrase backups, transaction confirmation emails and browser activity all leave traces on devices. Forensic examination cannot always establish current holdings, but it can often establish that holdings exist or existed — which is frequently enough to trigger disclosure obligations and further inquiry.

Betting and gambling accounts

Betting apps and their notification and transaction histories can reveal both undisclosed winnings and relevant patterns of dissipation of matrimonial assets.

Email and document trails

Statements, dividend notices, loan approvals, invoices from an undeclared side business — much of it arrives by email or sits in cloud storage. Where an account is lawfully accessible, cloud data extraction can surface records the account holder assumed were long buried. Our article on cloud data as evidence covers what these accounts typically contain.

Browser history and shared computers

A family computer used by both parties can hold browsing history, saved bookmarks, autofill entries and downloaded statements pointing to institutions never mentioned in disclosure. Computer forensics can recover this material — including some deleted history — in a documented, defensible way.

Deleted records

Deleting files and messages does not always destroy them. Deleted data retrieval can sometimes recover removed documents and conversations, though recovery is never guaranteed and depends on the device, storage type and time elapsed. A reputable examiner will assess the likelihood honestly before any work begins.

The lawful-access line

This point matters enormously: digital forensics in family law only works with lawfully accessed data. That generally means your own devices and accounts, genuinely shared devices, or material obtained through proper legal channels such as court orders and subpoenas. Logging into a former partner’s private email or banking app without authority — even with a password you once shared legitimately — may breach Commonwealth and state laws, can render the evidence unusable, and can seriously damage your own position. If the information you need sits behind someone else’s login, the answer is a legal process, not a password.

How forensics fits alongside lawyers, accountants and subpoenas

Device forensics rarely stands alone in an asset investigation. It works best as one part of a coordinated approach:

  • Forensic accountants analyse the financial records themselves — tracing transactions, valuing businesses and identifying anomalies in what has been produced.
  • Subpoenas and disclosure orders through the Federal Circuit and Family Court of Australia can compel banks, exchanges and other institutions to produce records. But subpoenas need a target: you must know, or reasonably suspect, that an account exists.
  • Digital forensics frequently supplies that missing starting point. An artefact showing an app for an unfamiliar bank, or emails from a crypto exchange, gives lawyers a concrete basis to seek targeted disclosure or issue a subpoena — converting suspicion into an actionable line of inquiry.

Lifestyle evidence can play a supporting role too; spending visible on social media that doesn’t match disclosed income is discussed in our guide to social media evidence.

Keeping the evidence usable

Findings only matter if the court can rely on them. That means forensically sound imaging of devices rather than casual browsing, preserved metadata, a documented chain of custody, and reporting that explains methodology in plain terms. Where findings are contested, an expert witness can present and defend the analysis. Informal snooping, by contrast, risks altering data, destroying its evidentiary value and raising questions about how it was obtained.

When to consider a forensic examination

Not every property matter needs digital forensics. It is worth discussing with your lawyer when disclosed finances don’t match visible lifestyle, when a party controls businesses or crypto with limited records, when documents have been unusually “lost”, or when a shared computer or device may hold relevant history. An early, frank conversation about what is realistically recoverable — and what is not — protects you from wasted cost.
