Forensic Audit Evidence Analysis & Chain-of-Custody Documentation
Build litigation-proof forensic audit conclusions with documented evidence chains
What You Can Do
You can trace financial transactions across multiple accounts and entities, document complete chain-of-custody for audit evidence, identify fraud indicators and anomaly patterns, and construct defensible audit conclusions that satisfy both forensic rigor and legal admissibility requirements. This skill provides structured protocols for adversarial skepticism, hostile cross-examination preparation, and quantification of losses or damages with transparent methodologies.
Features
systematically document fund flows across bank accounts, entities, and jurisdictions with detailed sourcing and destination mapping
create legally compliant evidence trails showing collection, handling, analysis, and preservation of financial records
identify embezzlement patterns, duplicate payments, vendor manipulation, check tampering, and asset misappropriation with quantified anomalies
build bulletproof findings with documented assumptions, alternative hypotheses, and limitations explicitly addressed
develop chronological, cause-effect audit narratives that connect disparate transactions into coherent fraud schemes
calculate loss amounts using defensible methodologies with documented calculation steps and sensitivity analysis
structure audit work papers to meet SEC, DOJ, banking regulator, and court admissibility standards
develop analytical procedures when source documents are missing, corrupted, or destroyed
Example Output
Example 1: Embezzlement Scheme Analysis
Suspect Activity: Accounts payable clerk processing payments to shell vendor
- Transaction Chain: Check register → bank clearing documents → payee bank deposits → wire transfers to personal account
- Anomalies Identified: (3) Payments to new vendor with no purchase orders; duplicate invoice amounts; post-dated check clearing delays
- Quantified Loss: $287,400 across 24 transactions (Sept 2022–March 2024)
- Evidence Status: ✓ Original cancelled checks obtained; ✓ Bank statements certified; ✓ Vendor registration documents analyzed; ⚠ Invoices may be forged (handwriting analysis recommended)
Example 2: Fund Tracing Across Entities
- Source: Corporate wire transfer $500,000 to subsidiary (ostensibly for equipment purchase)
- Trail: Subsidiary bank account → overnight wire to offshore entity → diverted to director's personal account
- Documentation: Bank statements, wire instructions, board minutes, director disclosures reviewed
- Finding: Unauthorized diversion with falsified equipment invoice; director conflict of interest not disclosed
Example 3: Cross-Examination Memo
Potential Opposing Arguments: Payments could be legitimate vendor rebates, not kickbacks
- Counter: Vendor had no business address; wire recipient is CEO's relative; no formal rebate agreements exist in files (✓ documented)
- Limitation: Analysis limited to 18 months due to record destruction; earlier patterns unknown
- Assumption: Bank statements assumed accurate (third-party verified source)

This skill automates the complex work of calculating material price, quantity, and usage variances; labor rate and efficiency variances; and overhead variances across products, departments, and time periods. You input production data and standard cost tables, and Claude processes the variance calculations, organizes findings by significance, and generates detailed narratives explaining root causes of deviations. This transforms hours of spreadsheet manipulation into a structured analysis package ready for management review and variance committee meetings.

You can build comprehensive standard costing systems that allocate indirect costs across products and production departments using appropriate cost drivers. Claude helps you calculate material, labor, and overhead variances, compare actual costs to standards, and investigate root causes of significant deviations (typically >5-10%). This enables data-driven decisions on product pricing, profitability by line, and operational improvements.
