How to Write Numbers in Words for Bank Cheques, Invoices, and Legal Contracts

Introduction: Why Accuracy Matters in Commercial Banking

Writing monetary sums in both figures and words is a universal legal safeguard dating back hundreds of years. Under the Negotiable Instruments Act, if there is a discrepancy between the amount expressed in figures and words on a bank cheque, the amount written in words takes precedence.

A single grammatical ambiguity or misplaced comma can cause check rejection, delayed bank clearance, or vulnerability to fraudulent alterations.

4 Rules for Writing Bank Cheques Properly

1. Start Without Leaving Leading Space: Begin writing immediately adjacent to the “Rupees” printed prompt so unauthorized prefixes cannot be inserted.
2. Always Terminate with 'Only': Conclude the words with “Only” (e.g., “Twenty-Five Thousand Four Hundred Rupees and Fifty Paise Only”).
3. Hyphenate Compound Numbers Between 21 and 99: Numbers like twenty-one, fifty-five, and ninety-nine require hyphens in standard commercial English.
4. Draw a Strike-Through Line in Figures: When writing the numeric box (₹ 25,450/-), always append a forward slash and hyphen (/- ) to prevent trailing zero additions.
