Financial records can be important in commercial disputes involving questions about revenue, costs, profits, assets, liabilities, transactions, business value, or financial loss.
The records that may be relevant will depend on the nature of the dispute and the specific financial questions being considered. A dispute accountant or forensic accountant may therefore need to review information from several sources rather than relying on one set of accounts.
For solicitors, identifying the relevant financial records can help clarify the accounting issues that may require further analysis.
Why Financial Records Matter in Commercial Disputes
Commercial disputes can involve questions about the financial effect of a transaction, agreement, business decision, or alleged wrongdoing.
Accounting records may provide information about the business's financial position and performance and may help demonstrate how particular figures have been calculated. They can also allow comparisons between different periods or between actual results and other financial information.
No single financial record necessarily provides the complete picture. Different records may have different purposes, levels of detail, and limitations. A forensic accountant may therefore consider whether figures are consistent across available sources and whether further information is required.
For an overview of the wider role of accounting in disputes, see the Types of Accounting Disputes guide.
Key Financial Records That May Be Relevant
There is no universal list of financial documents required for every commercial dispute. The appropriate records will depend on the issues being examined.
Statutory Accounts and Financial Statements
Annual accounts can provide information about a company's reported financial performance and position for particular periods.
Depending on the company and the relevant period, these may include:
- Profit and loss accounts
- Balance sheets
- Cash flow statements
- Notes to the accounts
- Accounting policies
- Supporting disclosures
Reviewing accounts across several periods may help identify changes in revenue, costs, assets, liabilities, or profitability.
Where a particular transaction or calculation needs to be examined in greater detail, underlying accounting records may also be required.
Management Accounts
Management accounts can provide more frequent financial information than annual statutory accounts.
They may contain information about:
- Revenue
- Direct and indirect costs
- Gross margins
- Operating expenses
- Profit
- Cash flow
- Individual business units or locations
The level of detail and preparation methods can vary between businesses. A dispute accountant may therefore consider how the management accounts were prepared and whether the figures are consistent with other available records.
General Ledger and Trial Balance
The general ledger contains detailed accounting entries recorded within an accounting system. A trial balance provides a summary of account balances at a particular point in time.
These records can be relevant where the dispute requires analysis below the level of published financial statements.
For example, they may help an accountant examine particular categories of income or expenditure and trace reported figures back to underlying accounting entries.
Bank Statements
Bank statements can provide transaction-level information about money entering and leaving business accounts.
Depending on the dispute, they may be relevant when examining:
- Payments to or from particular parties
- Transfers between accounts
- Business receipts
- Business expenditure
- The timing of payments
- Transactions requiring further explanation
A bank transaction alone may not establish the purpose or commercial context of a payment. It may therefore need to be considered alongside accounting records and other supporting information.
Invoices and Credit Notes
Sales invoices can provide information about amounts charged to customers and the timing of particular transactions. Purchase invoices can provide information about expenditure recorded by the business.
Credit notes may also be relevant where reported revenue or costs have subsequently been adjusted.
Where a dispute concerns particular transactions, these records may help reconcile accounting entries with the underlying commercial activity.
Payroll and Remuneration Records
Payroll records may be relevant where employee costs, director remuneration, bonuses, or other payments form part of the financial issues being examined.
The analysis might involve comparing remuneration across different periods or examining how particular payments have been recorded.
The relevance of these records will depend on the issues in dispute.
Budgets, Forecasts and Business Plans
Budgets and forecasts can be relevant where a dispute involves expected financial performance or a claimed loss.
These documents may show what management expected the business to achieve when the forecast was prepared.
A forensic accountant may consider:
- When the forecast was prepared
- The assumptions used
- The information available at the time
- Actual performance compared with forecast performance
- Changes made to later forecasts
A historical forecast should not automatically be treated as proof of what would have happened. Its preparation date, purpose, assumptions, and subsequent performance may all need to be considered.
Commercial Records That May Support the Accounting Evidence
Financial records are sometimes best understood alongside relevant commercial documents.
Contracts and Agreements
Contracts can contain information about pricing, payment terms, revenue arrangements, obligations, and other matters that may affect financial analysis.
Where a financial calculation depends on the terms of a commercial agreement, the relevant accounting records may need to be considered alongside that agreement.
Customer and Supplier Records
Customer records, supplier information, purchase orders, sales records, and related documentation may provide additional context for accounting entries.
Depending on the dispute, these records may help explain changes in revenue or expenditure or clarify the timing of particular transactions.
Internal Correspondence
Emails and other business communications may provide context concerning financial decisions, forecasts, transactions, or changes in commercial arrangements.
Their relevance will depend on the particular issues being investigated.
Records That May Matter in Loss Claims
Where a commercial dispute involves a claim for financial loss, the relevant records may extend beyond historical accounts.
For more detail on the accounting approach to financial loss, see the Loss Quantification Guide.
Historical Trading Data
Historical revenue, costs, margins, and profitability may provide information about the business before the event or circumstances being considered.
The appropriate historical period will depend on the nature of the dispute and the financial question being addressed.
Post-Event Financial Information
Actual financial performance after the relevant event may also be relevant.
This could include:
- Actual sales
- Actual costs
- Changes in staffing
- Changes in operating capacity
- Additional expenditure
- Changes in customer activity
Actual results can provide information about what happened after an event, although interpreting those results may require consideration of other factors affecting the business.
Records Relating to Mitigation
Records showing steps taken to reduce or avoid financial losses may also be relevant.
Depending on the circumstances, these could include information about alternative suppliers, replacement equipment, additional staffing, alternative sales channels, or other operational changes.
The accounting analysis should distinguish between documented financial information and assumptions that require further consideration.
Records Relevant to Business Valuation Disputes
The financial records required in a business valuation dispute may differ from those needed for a straightforward loss calculation.
Potentially relevant information may include:
- Historical financial statements
- Management accounts
- Detailed revenue and cost information
- Budgets and forecasts
- Cash flow information
- Asset schedules
- Debt information
- Details of shareholder or director transactions
- Information about the company's ownership structure
The records needed will depend on matters such as the valuation date, the valuation question, the nature of the business, and the methodology being considered.
What If Financial Records Are Incomplete?
Commercial disputes do not always involve a complete set of financial records.
Documents may be unavailable, incomplete, inconsistent, or recorded differently across accounting systems.
In those circumstances, a forensic accountant may need to identify what information is available, consider its limitations, and assess whether other records can help address gaps.
This may involve reconciling information from different sources, examining underlying transactions, or considering alternative financial records.
Any analysis based on incomplete information should take the limitations of the available evidence into account.
How Solicitors Can Organise Financial Records for Expert Review
A structured document set can make it easier to identify the financial questions requiring analysis.
Identify the Financial Issues First
It can be useful to identify the specific financial issues in dispute before gathering every potentially relevant accounting document.
For example, the issue may concern:
- The amount of a claimed loss
- The value of a business or shareholding
- The accuracy of particular transactions
- The financial effect of a commercial event
- Differences between competing calculations
The relevant records can then be considered in relation to those issues.
Separate Primary Records From Summaries
A spreadsheet or management report may summarise financial information, while the underlying accounting records may provide greater detail.
Where a calculation relies on a summary, it may be necessary to understand how the figures were derived and whether the underlying records are available.
Keep the Relevant Period Clear
Organising financial records chronologically can help distinguish information relating to periods before, during, and after the event or transaction in dispute.
The appropriate period will depend on the circumstances rather than following a fixed rule.
Record Missing Information
If potentially relevant records cannot be located, it can be useful to identify what is missing.
This can help an expert understand the evidential limitations when carrying out an accounting analysis.
When Might a Dispute Accountant Review Financial Records?
A dispute accountant may be instructed where specialist accounting analysis is required in relation to a financial dispute.
Depending on the circumstances, the work may involve reviewing financial records, analysing transactions, quantifying loss, considering valuation information, or preparing an expert report.
The scope should be based on the financial questions that the expert has been asked to address. More information about the instruction process is available in the Instructing a Dispute Accountant guide.
Conclusion
The financial records relevant to a commercial dispute depend on the nature of the dispute and the specific accounting questions involved.
Statutory accounts, management accounts, general ledgers, bank statements, invoices, payroll records, forecasts, contracts, and other supporting documents may each provide different information.
Rather than relying on one source, a dispute accountant may need to consider information from several records and take account of gaps, inconsistencies, and other evidential limitations.
For solicitors, identifying the financial issues first and organising the relevant records around those issues can provide a practical starting point for further accounting review.
