Strong evidence that a cause of action exists is documentary and contemporaneous — clear contracts, signed agreements, invoices, notices, delivery receipts, emails and messages, bank records, statutory filings, CCTV/photographs, and any expert or forensic reports — backed up by sworn witness affidavits or admission by the other party; together these items establish the essential facts (who did what, when, where, and why) and link the defendant’s conduct to the legal right allegedly violated. Presenting the case step-by-step improves clarity and persuasion: collect and index all primary documents; create a chronological narrative that ties each fact to the specific element of the cause of action; prepare short, focused witness statements and an evidence bundle with tabbed annexures; draft a concise cause-of-action paragraph in the plaint that cites the annexures; run a pre-filing audit to identify gaps and amend before filing; and, if challenged, file targeted amendments or an appeal showing how the pleadings and documents, read together, establish an arguable cause — this disciplined, documentary-first approach minimizes ambiguity and greatly reduces the risk of rejection.
