A Legal Analysis under Philippine Law

I. Introduction

In everyday commercial transactions in the Philippines, receipts serve as the primary documentary evidence of payment and the discharge of an obligation. Whether issued by a business establishment, a professional, or a private individual, receipts commonly contain the amount due expressed in two forms: Arabic numerals (figures) and words (e.g., “Five Thousand Pesos Only”). When these two expressions conflict, a fundamental question arises: which controls the legal effect of the document?

Philippine law resolves this issue through a combination of statutory interpretation rules, commercial usage, and established jurisprudence. The settled principle is that, absent clear evidence to the contrary, the amount expressed in words prevails over the amount in figures. This rule is rooted in the greater reliability of words as an indicator of true intention and their relative resistance to undetected alteration.

II. Legal Nature of Receipts

A receipt is an acknowledgment in writing that money or property has been received in satisfaction of an obligation (Civil Code, Art. 1249 in relation to Art. 1178). It is not a contract of sale or a negotiable instrument but a unilateral declaration by the creditor or his authorized representative that payment has been made. As such, it is admissible as evidence of payment under the best-evidence rule and the parol-evidence rule exceptions.

Receipts fall into several categories under Philippine law:

Official receipts (BIR-registered, required for VAT-registered persons);
Cash sales invoices or non-VAT receipts;
Provisional or temporary receipts;
Electronic or digital receipts (governed by Republic Act No. 8792, the Electronic Commerce Act).

Regardless of form, the same interpretive principles apply when a discrepancy between words and figures appears on the face of the document.

III. Governing Legal Framework

A. Civil Code Provisions on Interpretation of Documents

The Civil Code supplies the primary rules:

Art. 1370: If the terms of a contract (or document) are clear and leave no doubt as to the intention of the parties, the literal meaning of the stipulations shall control. When words and figures conflict, the document on its face contains an internal ambiguity.
Art. 1371: If the contract is ambiguous, the intention of the parties shall be ascertained from the words used, the circumstances surrounding its execution, and the conduct of the parties thereafter.
Art. 1374: The various stipulations of a contract shall be interpreted together, attributing to the doubtful ones that sense which may result from all of them taken jointly.

Because words are more difficult to alter without leaving obvious traces (erasure, different ink, spacing irregularities), courts attribute greater weight to them as the more reliable expression of the parties’ true agreement.

B. Analogy to the Negotiable Instruments Law

Although a receipt is not a negotiable instrument, Section 17 of Act No. 2031 (Negotiable Instruments Law) provides persuasive statutory analogy:

“Where the sum payable is expressed in words and also in figures and there is a discrepancy between the two, the sum denoted by the words is the sum payable; but if the words are ambiguous or uncertain, reference may be had to the figures to fix the amount.”

Philippine courts have consistently extended this commercial principle to ordinary receipts, invoices, and other commercial documents on the ground that the same policy considerations—prevention of fraud and protection of the integrity of written evidence—apply with equal force.

C. Other Relevant Statutes

Electronic Commerce Act (R.A. 8792) and its Implementing Rules: Electronic receipts and digital signatures are given the same legal effect as paper documents. The rule on words prevailing remains unchanged.
Consumer Act (R.A. 7394): In transactions involving consumers, any ambiguity in the receipt is construed strictly against the seller or service provider (Art. 24, Civil Code in relation to consumer-protection provisions).
Tax Code and BIR Regulations: Official receipts must reflect the correct amount. A discrepancy may trigger audit or assessment, but the BIR treats the amount in words as the presumptively correct figure for purposes of tax liability unless the taxpayer proves otherwise through clear and convincing evidence.

IV. The Prevailing Rule: Words Control

The rule is uniform and long-standing:

In case of discrepancy between the amount written in words and the amount in figures on a receipt, the amount in words prevails.

This doctrine rests on three interlocking rationales:

Security against tampering – Figures are easily changed by adding or deleting a zero or a decimal point. Words require rewriting entire phrases and are far more noticeable when altered.
Expression of true intention – The person writing the receipt must consciously spell out the amount, reducing the likelihood of clerical error.
Commercial certainty – Businesses and the public must be able to rely on a single, objective standard without constant resort to extrinsic evidence.

The rule applies whether the words state a higher or lower amount than the figures. Thus:

Receipt shows “₱10,000.00” in figures but “Ten Thousand Five Hundred Pesos” in words → ₱10,500.00 is the amount acknowledged as received.
Receipt shows “₱50,000.00” in figures but “Five Thousand Pesos Only” in words → ₱5,000.00 is the controlling amount.

V. Jurisprudential Support

Philippine jurisprudence has repeatedly affirmed the principle without deviation. The Supreme Court has held that the amount in words is the controlling stipulation in:

Checks and other negotiable instruments (direct application of NIL Sec. 17);
Deeds of absolute sale and promissory notes;
Ordinary receipts and invoices issued in the ordinary course of business.

The Court has emphasized that the presumption is juris tantum—rebuttable only by clear and convincing evidence of mutual mistake, fraud, or that the words themselves were the product of clerical error. Mere typographical error in figures will not overcome the words.

VI. Exceptions and Qualifications

The rule is not absolute. Exceptions include:

Ambiguous or uncertain words – If the words are illegible, use non-standard spelling, or are susceptible of two reasonable interpretations, reference may be made to the figures (NIL Sec. 17, applied by analogy).
Clear and convincing proof of mistake – Parol evidence is admissible to show that both parties actually intended the figure amount and that the words were a scrivener’s error. The burden rests on the party asserting the mistake.
Fraud or forgery – If the entire receipt or the words portion is proven forged, neither amount controls; the court will determine the true transaction amount from other evidence.
Subsequent conduct or admission – If the issuer later issues a corrected receipt, makes a partial refund, or admits in writing or under oath that the figure was correct, the presumption in favor of the words may be overcome.
Mathematical impossibility or patent absurdity – Words stating “One Million Pesos” when the transaction is for a ₱1,000 item and surrounding circumstances clearly indicate a typographical error may be disregarded.

VII. Practical and Commercial Implications

For Issuers (Merchants, Professionals, Government Offices)

Always ensure consistency between words and figures before issuance. Modern POS systems and accounting software automatically convert figures to words precisely for this reason.
When a discrepancy is discovered after issuance, the proper procedure is to issue a new corrected receipt and obtain the surrender of the original (or annotate both copies if the original cannot be retrieved).
In VAT-registered transactions, failure to reconcile the discrepancy may result in disallowance of input tax credits or deficiency assessments.

For Recipients (Consumers, Buyers)

Immediately verify both amounts upon receipt. If a discrepancy exists, demand immediate correction before leaving the premises.
Retain the original receipt; photocopies or electronic images are secondary evidence.
In disputes, the recipient may rely on the words as prima facie evidence of the correct amount paid.

In Litigation

When a receipt is offered in evidence:

The court will first apply the “words-prevail” rule.
Only if the party challenging the words presents clear and convincing evidence will the court depart from the presumption.
In criminal cases (e.g., estafa, qualified theft involving receipts), the amount in words usually determines the value of the thing taken or the damage suffered.

VIII. Electronic and Digital Receipts

With the widespread adoption of e-receipts, QR-coded invoices, and mobile payment confirmations, the same rule applies. The Electronic Commerce Act expressly provides that electronic documents have the same legal effect as paper documents. Most digital receipt generators automatically populate both fields from the same data source, minimizing discrepancies. When they occur (e.g., manual override or software glitch), courts still accord primacy to the words field.

IX. Conclusion

Under Philippine law, the amount written in words on a receipt is the controlling and prevailing amount in the event of any discrepancy with the figures. This doctrine, grounded in the Civil Code, reinforced by the Negotiable Instruments Law by analogy, and consistently upheld by jurisprudence, serves the twin purposes of commercial security and evidentiary reliability. Parties to any transaction are well-advised to treat the words as the definitive statement of the sum acknowledged, and to resolve any inconsistency at the moment of issuance rather than in subsequent dispute or litigation. The rule remains one of the clearest and most stable principles in Philippine commercial and evidentiary law.
