Crypto Tracing in Australian Legal Matters

Where Crypto Tracing Starts: The Bank Statement

Start crypto tracing by finding bank transfers, card payments and PayID payments to or from a cryptocurrency exchange. These payment channels show the entry and exit points when someone buys crypto with money or converts it back.

1. Gather statements for the relevant accounts and investigation period. Retain the original PDFs alongside any extracted ledger.
2. Search transaction descriptions for exchange names and payment processors. Record the description exactly, including any payment reference.
3. Group possible exchange payments across accounts and years. Compare recurring references and identify changes in the name appearing on the statement.
4. Confirm the recipient through payment details or exchange records. Keep a possible crypto payment separate from a confirmed exchange deposit until that connection is established.

A processor’s name can appear in place of the exchange’s name. A card description can also be shortened, so a name-only search can miss payments. Use the bank’s fuller payment record to connect an unclear description to the recipient.

The useful output is a schedule of suspected exchange payments with amounts, account details and source references. It gives you a defined starting point for requests to the bank or exchange. AUSTRAC’s digital currency guide explains why conversion between money and crypto is an identifiable point in the trail.

FinTrace saves hours of monotonous statement review at this stage by bringing supplied PDF statements into one searchable ledger and a clear findings report. The analysis flags crypto activity and suspicious transactions across the supplied accounts, with each finding tied to its source PDF filename and page. Lawyers and forensic accountants can use that evidence to direct the next record request.

Identifying Exchange Deposits and Withdrawals

Pair confirmed deposits to an exchange with credits received from it to calculate net bank funding over the same period. This gives an initial estimate of money that has not returned through the bank accounts you have examined.

For a hypothetical Australian-dollar example, bank statements show $24,000 paid to an exchange and $9,000 returned. Net funding is $15,000. That figure identifies money to account for through exchange and wallet records.

Net funding is not a current crypto balance or valuation. Trading losses, fees and withdrawals to another bank or wallet can change what remains. A $15,000 funding difference cannot establish that the account holder still owns $15,000 in cryptocurrency.

Reconcile each bank payment with the exchange’s deposit or withdrawal record. Match the amount and reference, allowing for documented processing delays or fees. Record the currency and time zone used by the exchange before comparing times.

Peer-to-peer purchases leave a weaker bank trace because the payment can go to another individual. Obtain the order record or correspondence connecting that payment to the crypto transfer. Cash-for-crypto purchases can leave only an ATM withdrawal on the statement, which does not identify how the cash was spent.

If an apparent exchange payment is missing from the export, check the account identity and period covered before assuming funds disappeared. Search records for other accounts or payment services used in the transaction. A statement gap remains a missing period, not evidence that money went into crypto.

Getting Exchange Records

Obtain the exchange’s records to connect bank funding with the account holder and the addresses used for crypto transfers. A targeted request needs the correct legal entity, account identifiers and investigation period.

AUSTRAC now uses the term virtual asset service provider, or VASP, for the regulated category that includes exchanges. Its provider overview links to the public register. Establish the provider’s legal identity before addressing a compulsory request.

Where the court’s rules or a statutory power permit it, a subpoena, production order or authorised notice can require relevant records held by the exchange. Registration with AUSTRAC does not itself give a private investigator a power to compel disclosure.

Request records that identify the account holder and connect the payments to crypto movements. A focused schedule can seek:

• Account-opening and identity verification records, including account identifiers.
• Fiat deposit and withdrawal records, with linked bank details and payment references.
• Crypto deposits and withdrawals, including wallet addresses, networks and transaction identifiers.
• Trading records, internal transfers and balance records needed to reconcile the period.

The records produced depend on the request’s scope and what the exchange holds. Seek actual transfer records as well as an account balance summary. A transaction identifier connects an exchange withdrawal to a specific blockchain entry.

For drafting and service considerations, use the guide to subpoenaing bank records alongside the rules governing your exchange request.

Account-Holder Exports and Binance Statements

An account holder can download transaction history from an exchange and provide the original export. Binance’s transaction history instructions explain how to generate records for selected periods and accounts, then download the report.

For a Binance CSV or statement, retain the downloaded file unchanged and work on a copy. Record the selected period, accounts and any filters used. Request separate deposit and withdrawal histories where the general export does not show the addresses or transaction identifiers needed for tracing.

Check the export’s actual columns before treating it as a complete account history. Reconcile the bank payments and compare the self-downloaded export with records produced directly by the exchange under subpoena. That comparison can expose an omitted account, a restricted date range or missing transaction types.

Offshore Exchanges

An offshore exchange can require a different disclosure and service route. Identify the entity holding the records, its location and the court’s power to make and serve the requested order. An Australian brand presence does not establish that an Australian company holds every customer record.

Preserve the known payment details and wallet addresses while the legal process proceeds. If the recipient’s identity is unknown, preliminary discovery can be relevant to identifying a prospective defendant. Its availability depends on the jurisdiction’s rules and the evidence supporting the application.

Following Funds on the Blockchain

Follow cryptocurrency on a public blockchain from an address or transaction identified in reliable records. The ledger shows transfers between addresses, but it does not ordinarily name the people controlling them.

1. Establish the network and starting transaction. The same-looking address or token name must be checked against the correct blockchain.
2. Record the transaction identifier, amount and recipient address for each relevant transfer. Keep the underlying blockchain record with the tracing schedule.
3. Connect each claimed owner to evidence. Exchange identity records or an admission can support attribution of an address to a person.
4. Reconcile the traced movements with exchange records. Separate observable transfers from assumptions about ownership or the route taken by commingled funds.

A mixer combines transactions and makes the connection between incoming and outgoing funds harder to establish. A cross-chain bridge moves value between networks, requiring evidence of the corresponding transaction on the destination chain. These can interrupt a straightforward trail without proving the money is untraceable.

Specialist on-chain analytics can help investigate those movements once addresses are known. The blockchain analysis guide explains that next stage. Disclosure and valuation in a property matter are covered in crypto in divorce.

Presenting Blockchain Evidence in Court

Blockchain records and an expert’s conclusions about them are different kinds of evidence. In federal proceedings, section 79 of the Evidence Act 1995 (Cth) provides an exception to the opinion rule for opinions based on specialised knowledge. The opinion must be wholly or substantially based on the witness’s knowledge acquired through training, study or experience.

An expert report explains how the transactions support the conclusion. Identify the tracing tool and method, the source records and the evidence used to attribute addresses. State the assumptions and limits, including any unresolved connection after a mixer or bridge.

The Federal Court’s Expert Evidence Practice Note and code require the expert to explain the factual basis and reasoning. The expert’s paramount duty is to assist the court impartially. State and territory proceedings require the applicable evidence law and court rules.

Before using the trail, confirm that the bank payment connects to an exchange record and the exchange record connects to the identified blockchain transaction. Each later ownership claim needs its own evidence. Where a connection is missing, identify the record needed to resolve it and make the next request specific.
