Financial-record review subtopic
Source deposit tracing
When deposits in an account need to be matched against income, contributions, and transfers — and the ones without supporting documentation have to be flagged for follow-up before any conclusion is drawn from them.
A financial-record review subtopic supported by FinancialProofReview.
What this is
Source deposit tracing in plain language
Source deposit tracing examines each credit transaction in a bank account during a defined period and identifies, from supporting records, where the deposit came from. A deposit is “supported” when documentation explains its origin: a paycheck stub matching the date and amount, a wire transfer record from a known counterparty, a deposit slip with check images, or a transfer log from another account already in scope. A deposit is “unsupported” when none of those records explain it — the credit posted, but its source cannot be traced from the documentation available.
The exercise is not about whether a deposit is suspicious; it is about whether it is documented. A deposit can be entirely legitimate and still be unsupported, because the supporting record was never collected. Conversely, a deposit that matches a known income source is supported regardless of size. The tracing produces a deposit-by-deposit schedule where each entry has either a documented source or a flagged gap. Partial support — a deposit slip exists but the underlying check image does not, or a wire is recorded but the originating account is unidentified — is captured as a separate classification. The output is structured enough that counsel, a fiduciary, or another reviewer can see at a glance which credits stand on documentation and which require follow-up.
Why it matters
Why unexplained deposits change every downstream question
In divorce, estate, fraud, and fiduciary matters, unexplained deposits raise specific questions. In divorce, deposits that do not match a disclosed income source may suggest undisclosed earnings, gifts, or commingled funds. In an estate accounting, deposits not traceable to a documented source may need explanation to beneficiaries. In a fraud-loss review, unexplained deposits to a controlled account may indicate proceeds requiring further investigation. In a fiduciary accounting, deposits without documented sources can become contested entries in the next reporting cycle.
Without tracing, reviewers cannot distinguish documented income — which is not a question — from undocumented activity, which is. The risk of skipping this step is reaching conclusions that look thorough but rest on a deposit history no one has actually checked. The benefit of doing it is the opposite: a deposit schedule where each entry is either supported by a specific document or flagged as requiring follow-up, with the reasoning in writing and the underlying document available for review by anyone who needs to verify the conclusion later.
What records are involved
Documents the review consults
Source tracing requires the deposit-side records from the bank and the supporting documentation that should match those deposits. The review consults:
- Bank statements with deposit detail (date, amount, type)
- Deposit slips with check images, where available
- Paycheck stubs and payroll records
- Wire transfer records (incoming wires with originator detail)
- Account-to-account transfer documentation
- Third-party contribution records (gifts, loans, settlements)
- Counterparty bank records where the source is another account
- Tax returns identifying disclosed income sources
How a review handles this
Extracting deposits and matching sources
The review starts with a complete deposit extraction: every credit transaction in the account during the relevant period, with date, amount, and any descriptive text from the statement. For each deposit, the review attempts to identify the source using available documentation. A paycheck stub matching the date and net amount supports a payroll deposit. A wire transfer record with the originator identified supports an incoming wire. A transfer from another known account in scope supports an internal transfer — the matching debit must be confirmed on the source-account statement.
Where supporting documentation exists, the deposit is classified as supported and linked to the document. Where no documentation can be located, the deposit is classified as unsupported and flagged. Where partial documentation exists — a deposit slip with no underlying check image, a wire log with no originator — the deposit is classified as partially supported with the specific gap noted.
The deposit schedule is then reviewed for patterns: recurring unsupported deposits of similar amounts (potentially undisclosed income), one-time large unsupported deposits (potentially gifts, loans, or settlements), and round-number cash deposits (which often warrant separate scrutiny). The output is a structured table of every deposit, its classification, and where supported, the document supporting it. Conclusions about whether the unsupported deposits are material to the matter belong to counsel, the fiduciary, or the reviewer leading the engagement — not to the source-tracing exercise itself.
What the review can produce
Workpaper outputs for source deposit tracing
- Complete deposit schedule (every deposit, by date)
- Source-match column (linking each deposit to supporting documentation)
- Supported-vs-unsupported deposit summary
- Unsupported-deposit list with dates, amounts, and account
- Partially-supported deposit list with the specific gap noted
- Follow-up questions for the depositor or records custodian
- Pattern analysis (recurring unsupported deposits, large one-time credits)
- Workpaper-style findings
Boundaries
What this review does not do
This is financial-record review support. It is not legal advice. The review classifies deposits as supported or unsupported based on documentation; it does not opine on whether unsupported deposits are unlawful, undisclosed, or otherwise material to a legal claim. Those determinations belong to counsel, the fiduciary, or the reviewing team. The review does not provide testimony, charging recommendations, agency findings, or law-enforcement authority. Outputs depend on the records made available; deposits remain unsupported until documentation reaches the review. No outcome is guaranteed; the usefulness of any review depends on the records and supporting documents available.
Methodology
Built on StatementProof workpapers
StatementProof is the structured workpaper system behind FinancialProofReview. Each engagement runs through the same disciplined process: source documents are indexed, transactions are reconciled, and findings are organized into reviewer-grade workpapers rather than narrative memos.
FinancialProofReview engagements are led by a Certified Fraud Examiner (CFE) with subject-matter expertise in forensic accounting, fraud examination, and financial-record review. Reviews are conducted from a fraud-examination perspective and produce workpaper-style analysis, summaries, timelines, and issue lists. The work is financial-record review support, not legal advice, law-enforcement authority, charging decisions, or testimony.
The methodology is operated by HopkinsForensic, an independent forensic-accounting firm.

Start with the deposits in question
If deposits are unexplained or unsupported, the first step is organizing what's there and identifying what records can support each deposit's source. For matters involving commingled funds or tracing analysis, see the Lowest Intermediate Balance Review add-on.
