Can Private Individuals Be Prosecuted for Forged Documents?
Introduction
Private individuals may incur criminal liability for falsifying private documents such as loan agreements, promissory notes, acknowledgment receipts, and personal receipts. The offense is punishable under Article 172(2) of the Revised Penal Code when the falsification causes damage to another person or is committed with the intent to cause such damage.
Forgery of a signature, however, does not automatically result in conviction. The prosecution must prove the specific act of falsification, the private character of the document, and the resulting damage or intent to cause damage. The charge must also be properly stated in the Information filed in court.
Governing Law: Article 172(2) of the Revised Penal Code
Article 172(2) of the Revised Penal Code covers a person who commits, in a private document, any of the falsification acts identified in Article 171, when the act causes damage to a third party or is done with intent to cause such damage.
As amended by R.A. No. 10951, Article 172 imposes the penalty of prision correccional in its medium and maximum periods and a fine of not more than P1,000,000 for the falsification offenses covered by the provision.
The relevant statutory provisions are found in The Revised Penal Code, Act No. 3815, as amended by R.A. No. 10951. The amended text expressly includes falsification in private documents and separately covers the knowing use of falsified documents.
Elements of Falsification of Private Documents
Under Supreme Court doctrine, the prosecution must establish the following elements:
- The accused committed an act of falsification identified in Article 171 of the Revised Penal Code, except the act under Article 171(7), as applicable;
- The falsification was committed in a private document; and
- The falsification caused damage to a third party or was committed with intent to cause such damage.
These elements were discussed in Manansala v. People of the Philippines, G.R. No. 215424, 2015, and Malabanan v. Sandiganbayan, G.R. No. 186329, 2017. The decisions emphasize that damage or intent to cause damage is an additional requirement when the falsification is committed by a private individual in a private document.
What Acts May Constitute Falsification?
Article 172(2) incorporates the falsification acts enumerated in Article 171. Depending on the facts, these may include making untruthful statements in a narration of facts, altering genuine documents, inserting false entries, making it appear that a person participated in an act or proceeding when that person did not, or attributing to a person statements or signatures that the person did not make.
In a signature-forgery case, the prosecution generally needs to show that the accused caused the document to appear as though it had been signed or executed by another person. A mere difference in handwriting is not, by itself, conclusive proof of criminal falsification; it must be connected to the accused and to the required damage or intent.
Forged Signatures on Loan Agreements and Promissory Notes
A loan agreement or promissory note may be treated as a private or commercial document depending on its nature and use. When the document is used to establish a credit transaction or obtain financial benefit, it may also be considered a commercial document for purposes of Article 172(1).
In Desmoparan v. People of the Philippines, G.R. No. 233598, 2019, the Supreme Court explained that loan applications, deeds of assignment, and promissory notes may be commercial documents because they promote or support credit transactions. The classification depends on the document’s function, not merely on its title.
A forged signature on a personal loan agreement may support a prosecution under Article 172(2) where the document is private and the prosecution proves that the forgery caused damage or was intended to cause damage. If the document was used to obtain money, enforce a nonexistent obligation, or impose liability on another person, those circumstances may help establish the required damage or intent.
Forged Signatures on Personal Receipts
Personal receipts may also be the subject of falsification. Examples include receipts falsely acknowledging payment, receipts bearing the forged signature of a creditor, or receipts altered to show a payment that was never made.
The prosecution must prove more than the falsity of the signature. It must show that the accused committed or caused the falsification and that the receipt was intended to prejudice another person or was actually used in a manner that caused damage.
For example, a falsified receipt may cause damage if it is used to defeat a legitimate claim, obtain the release of property, misrepresent the settlement of a debt, or induce a court or another person to rely on a nonexistent payment.
Damage or Intent to Cause Damage
Damage or intent to cause damage is indispensable under Article 172(2). The damage need not always be proven as a completed financial loss if the evidence establishes a specific intent to prejudice another person.
In Tan, Jr. v. Matsuura, et al., G.R. No. 179003, 2013, the Supreme Court explained that falsification in a private document requires independent evidence of damage or intent to cause damage. The falsity of the document alone is insufficient.
Potential forms of damage may include:
- Being made liable for a loan that the person did not obtain;
- Loss of the right to collect an unpaid debt;
- Release of property or money based on a false receipt;
- Use of the falsified document in court or before a government agency; or
- Damage to a person’s property, credit, legal rights, or interests.
The evidence should identify the person prejudiced, the right or interest affected, and the connection between the falsified document and the injury or intended injury.
Who May Be Prosecuted?
Article 172(2) may apply to any private individual who personally commits the falsification or participates in causing it to be made. Liability may be established through direct evidence, documentary evidence, expert examination, admissions, or circumstantial evidence.
Actual handwriting evidence is not always required. In Satuaito, et al. v. People of the Philippines, G.R. Nos. 239523-33, 2025, the Supreme Court recognized that circumstantial evidence may establish a private individual’s participation when direct evidence is unavailable.
Relevant circumstances may include exclusive possession of the document, control over its preparation, knowledge of the transaction, benefit received from its use, instructions given to another person, or conduct showing consciousness of guilt. The circumstances must form a coherent chain that proves guilt beyond reasonable doubt.
Presumption from Possession and Use
A person who possesses and uses a falsified document may, in appropriate circumstances, be presumed to be its author. This presumption is not conclusive and may be overcome by a satisfactory explanation showing that the person neither created nor knowingly used the falsified document.
In Brisenio v. People of the Philippines, G.R. No. 241336, 2021, and Desmoparan v. People of the Philippines, G.R. No. 233598, 2019, the Court recognized the evidentiary significance of possession and use, particularly where the accused benefits from the document and cannot reasonably explain its origin.
The presumption should be applied cautiously. Possession alone does not eliminate the prosecution’s obligation to prove every element of the offense beyond reasonable doubt.
Falsification Versus Use of a Falsified Document
Article 172 also punishes a person who knowingly introduces a falsified document in evidence or knowingly uses it to the damage of another or with intent to cause such damage. The penalty for the use of a falsified document is the penalty next lower in degree, subject to the statutory requirements.
Thus, two distinct forms of liability may arise:
| Conduct | Required showing |
|---|---|
| Falsification of a private document | The accused committed the falsification in a private document and caused damage or intended to cause damage. |
| Use of a falsified document | The accused knowingly used or introduced the false document and caused damage or intended to cause damage. |
A person who did not forge the document may still be criminally liable for knowingly using it. Conversely, a person who forged the document may face liability for falsification even if another person ultimately used it.
Importance of the Information
The accused may be convicted only of the offense charged in the Information or of an offense necessarily included in it. The allegations must sufficiently inform the accused of the factual acts being attributed to him or her.
In Malabanan v. Sandiganbayan, G.R. No. 186329, 2017, the Supreme Court stressed that conviction for an offense not alleged in the Information, and not necessarily included in the offense charged, violates the constitutional right to be informed of the nature and cause of the accusation.
An Information for falsification should therefore identify the document, the allegedly false entry or signature, the act attributed to the accused, the person prejudiced, and the damage or intended damage. A general allegation that a document was “falsified” may be vulnerable if it does not adequately state the material facts.
Evidence Commonly Used in Prosecution
A prosecution may rely on several types of evidence, including:
- The original loan agreement, promissory note, or receipt;
- Specimen signatures and handwriting comparisons;
- Testimony of the person whose signature was allegedly forged;
- Testimony of witnesses to the preparation, signing, or use of the document;
- Bank, payment, lending, or accounting records;
- Electronic messages or other communications concerning the document; and
- Evidence showing the accused’s possession, control, benefit, or motive.
The original document is generally important because the court must evaluate the alleged alteration or signature. Where the original is unavailable, the prosecution must account for its absence and establish the contents and falsification through admissible secondary evidence.
Common Defenses
An accused may contest authorship, knowledge, the private or commercial character of the document, the existence of damage, or the alleged intent to cause damage. The accused may also challenge the authenticity and admissibility of the prosecution’s documentary and testimonial evidence.
A credible explanation for possession or use may rebut the inference that the accused was the forger. Lack of participation, absence of benefit, mistake, lack of knowledge, or reliance on a document supplied by another person may be relevant, although these defenses must be supported by evidence.
The defense may also argue that the alteration was immaterial, that it did not change the document’s meaning, or that it caused no damage and was not made with intent to cause damage. Under Malabanan, criminal intent must be established where the circumstances show no malice, benefit, or prejudice.
Filing and Prosecuting the Complaint
The complaining witness should prepare a complaint-affidavit supported by the original or authenticated document, evidence of the alleged forgery, and proof of actual or intended damage. The complaint is ordinarily filed with the appropriate prosecutor for preliminary investigation when the applicable penalty and procedural rules require it.
The prosecutor determines whether probable cause exists for filing an Information. Courts generally respect the prosecutor’s determination, but judicial review remains available in exceptional cases involving grave abuse of discretion or a clear disregard of facts or law, as discussed in Tan, Jr. v. Matsuura, et al., G.R. No. 179003, 2013.
At trial, the prosecution must prove guilt beyond reasonable doubt. A finding of probable cause is only a determination that there is sufficient basis to proceed; it is not a finding of guilt.
Practical Examples
Example 1: Forged loan acknowledgment. A person signs the creditor’s name on an acknowledgment stating that a loan has been fully paid. If the document is used to defeat collection of the debt, the facts may support prosecution under Article 172(2), provided authorship or participation and damage or intent to cause damage are proven.
Example 2: Forged promissory note. A person prepares a promissory note bearing another individual’s forged signature and uses it to obtain a loan. Depending on the document’s nature and use, the conduct may involve falsification of a private or commercial document and may also give rise to other criminal charges if the elements are present.
Example 3: Possession without proof of knowledge. A person receives a falsified receipt from another individual and presents it without knowing that the signature is forged. Possession and presentation may raise questions, but criminal liability still requires proof of knowing use or participation beyond reasonable doubt.
Recommended Steps for Persons Reporting the Offense
- Preserve the original document and avoid writing, marking, or altering it.
- Obtain authentic signature specimens and records showing the actual transaction.
- Identify the person who prepared, possessed, submitted, or benefited from the document.
- Document the actual loss or the specific legal or financial injury threatened by the document.
- Secure relevant messages, payment records, bank documents, and witness statements.
- Consult counsel before filing the complaint to ensure that the allegations match Article 172 and the available evidence.
Final Observations
Forging a signature on a private loan agreement, promissory note, or personal receipt may constitute falsification under Article 172(2) of the Revised Penal Code. The decisive issues are not merely whether the signature is false, but whether the accused committed or knowingly participated in the falsification and whether the act caused damage or was intended to cause damage.
Complainants should build the case around the document’s authenticity, the accused’s participation, the circumstances of possession or use, and the specific prejudice suffered. Accused persons should examine authorship, knowledge, intent, damage, the sufficiency of the Information, and the admissibility and reliability of the prosecution’s evidence.
