Transaction evidence guide

What financial evidence matters in a transaction dispute?

Preserve the contemporaneous model, decision record, assumptions and source documents before the dispute changes the evidence landscape.

Quick answer

Transaction disputes can turn on the agreement, completion accounts, forecasts, representations, earn-outs, valuation assumptions, causation and damages. The financial evidence should be preserved, reconciled and source-linked. Legal counsel should define the issues and evidentiary standard; qualified forensic accountants, valuers or expert witnesses should perform specialist opinions where required.

Scope boundary

Legal counsel should define the legal issues, evidentiary requirements, privilege and specialist instructions.

Native files retain formulas, links, assumptions, metadata and version evidence that flattened outputs can lose.

The current public site evidence does not establish an expert-witness service. Any specialist role would require verified qualifications, independence and a specific written scope.
