Quick answer
If an inventory receiving report bears a signature you did not make or authorize, immediately dispute it in writing, stop the document from being used for payment or inventory accountability, and preserve the original and all related records. Do not alter, annotate, staple, or write on the questioned original.
A forged signature may support a criminal complaint for falsification, but the exact offense depends on the document and the people involved. An inventory receiving report may be treated as a private, commercial, public, or official document depending on how it was created and used. A public officer who falsified an official document by taking advantage of office may fall under Article 171 of the Revised Penal Code; a private person who falsified a public, official, or commercial document may fall under Article 172(1); falsification of an ordinary private document falls under Article 172(2), which additionally requires damage or intent to cause damage. Knowingly using a falsified document may also be punishable under Article 172(3).
Do not sign a replacement, admit receipt, or accept financial responsibility simply to “correct” the records. A replacement document can be prepared only if it accurately states what happened and clearly identifies itself as a correction—not as confirmation that the original transaction occurred.
Act immediately to prevent further use
Send a dated written notice to the people who control the transaction and records. Depending on the organization, this may include:
- The accounting, finance, accounts-payable, procurement, warehouse, inventory, or property unit
- Your supervisor, compliance officer, internal auditor, or legal department
- The supplier, carrier, customer, or other party relying on the report
- The records custodian or system administrator
State only facts you can personally confirm:
- The report’s date, reference number, purchase order, delivery, items, and amount
- Where and when you first saw it
- That the signature is not yours and was not placed with your authority
- Whether you received, inspected, counted, or accepted any of the listed goods
- Whether you were present at the stated time and place
- Any immediate action requested, such as holding payment, reversing an inventory posting, or restricting further use of the report
Ask recipients to acknowledge the notice and preserve the document, CCTV footage, access records, system logs, emails, messages, and transaction files. If payment or release of property is still pending, expressly request a temporary hold while the facts are verified.
Avoid stating that a named person “committed forgery” unless you have reliable evidence identifying that person. It is safer to say that the signature is unauthorized and that the circumstances require investigation.
Preserve the evidence properly
The questioned document is important, but so is the evidence showing how it was created, approved, circulated, and used.
Preserve or request preservation of:
- The original receiving report and every available copy
- The purchase order, delivery receipt, sales invoice, inspection report, stock card, inventory ledger, payment voucher, check, bank record, and acknowledgment
- Emails, text messages, chat messages, call logs, and calendar entries concerning the delivery
- CCTV recordings from the warehouse, receiving area, office, loading bay, and entrances
- Visitor logs, gate passes, vehicle records, guard logs, biometric records, and access-card data
- The report’s electronic file, version history, audit trail, upload history, timestamps, and user-account logs
- Printer, scanner, workflow, enterprise-resource-planning, and document-management records
- Names and contact information of guards, drivers, warehouse staff, inspectors, witnesses, and custodians
- Genuine signatures made by you near the relevant date on comparable business documents
Keep the original in a secure envelope or evidence folder and limit handling. Record who had custody of it and when it changed hands. Work from copies whenever possible. Do not trace the signature, mark similarities or differences on the original, apply chemicals, laminate it, or send it through an ordinary office scanner if doing so could damage or alter it.
For electronic records, preserve the native file and associated metadata rather than relying solely on screenshots or printouts. Screenshots can supplement—but should not replace—the underlying file and system logs.
Do not privately seize another person’s phone, computer, handwriting samples, or account credentials. Investigators and counsel can identify lawful methods for obtaining those materials.
Prepare a clear incident record
While events are fresh, make a chronological account covering:
- Your role and whether you were authorized to receive or inspect inventory.
- What delivery supposedly occurred.
- Where you actually were at the relevant time.
- How you discovered the report.
- Why you know the signature is not yours.
- Whether anyone had permission to sign on your behalf and, if so, the limits of that authority.
- Whether the goods existed, arrived, matched the order, or were accepted by someone else.
- Whether the report triggered payment, inventory entry, property accountability, tax documentation, or another official act.
- Who possessed or used the report after its creation.
- What notices and preservation requests you sent.
Attach copies of supporting documents, but keep an unaltered master set. If you later execute a complaint-affidavit, ensure that every material statement is based on personal knowledge or clearly identifies its source.
Request a controlled internal investigation
An employer or organization should secure the questioned record, restrict further processing, and compare the report against independent records of the delivery. A fair investigation should examine more than the appearance of the signature.
Relevant questions include:
- Did the goods physically arrive?
- Who counted and inspected them?
- Who generated, printed, scanned, uploaded, or approved the report?
- Which account or device recorded the transaction?
- Was the signature handwritten, copied from another document, pasted into a file, or applied electronically?
- Was anyone authorized to sign “for” the named recipient?
- Did the report cause payment, release of goods, inventory recognition, or assignment of accountability?
- Are there other reports bearing similar unauthorized signatures?
Internal discipline and criminal liability are separate matters. An employer should follow its disciplinary procedures and applicable labor rules rather than treating an allegation as automatic proof of misconduct.
If you are an employee being blamed for a shortage, payment, or unauthorized receipt, submit your denial in writing and request copies of the documents and policies being used against you. Do not sign a confession, repayment agreement, resignation, or waiver you do not understand.
Consider a criminal complaint
The Revised Penal Code expressly includes counterfeiting or imitating a handwriting, signature, or rubric among the acts of falsification. The current provisions are found in Articles 171 and 172, as amended by Republic Act No. 10951.
The document’s classification matters:
- Public or official document: This may include a document made or issued by a public officer in the performance of official duties, subject to the document’s actual nature and purpose.
- Commercial document: A report prepared and used in a business transaction may qualify, but not every document belonging to a business is automatically commercial.
- Private document: If it is neither public, official, nor commercial, Article 172(2) requires proof of damage to a third person or intent to cause such damage.
- Government document falsified by a public officer: Article 171 may apply only when the required connection between the officer’s position and the falsification is established.
- Knowing use: A person who did not create the false document may still face liability if the legal requirements for knowingly using it are proved.
The presence of a forged-looking signature does not by itself establish who made it, whether the suspected person acted knowingly, or which offense applies. Those issues depend on the original document, surrounding records, witnesses, intent, authority, and use.
A complaint may be brought to the Philippine National Police or National Bureau of Investigation for investigation and may be filed with the proper Office of the City or Provincial Prosecutor. The Department of Justice’s guidance on filing a complaint for preliminary investigation identifies the complaint-affidavit or sworn statement, investigation data form, witness affidavits, and supporting documents among the usual requirements. Confirm the current form, number of copies, filing method, and territorial office directly with the prosecutor’s office before filing.
Where a prosecutor’s preliminary investigation is required, the current framework includes the 2024 DOJ-NPS Rules on Preliminary Investigations and Inquest Proceedings. The prosecutor—not the complainant—determines whether the evidence meets the applicable standard for filing a case in court.
Other offenses, including fraud-related crimes, may be considered when the document was used to obtain payment or property. Their application is fact-dependent; a forged receiving report does not automatically establish a separate fraud offense.
If government funds or property are involved
Act quickly if the report relates to a government purchase, inspection, delivery, payment, or property acknowledgment. Send the factual written dispute and preservation request through the agency’s authorized channels, which may include:
- The head of the procuring entity or responsible office
- Accounting, property, supply, inspection, procurement, and internal-audit units
- The agency’s resident Commission on Audit auditor
- The Office of the Ombudsman when the facts indicate possible wrongdoing by a public officer
A government receiving report can affect payment, audit findings, property accountability, and the public record. Preserve the complete procurement and payment trail, not merely the signature page. The applicable procurement framework may depend on when the procurement began and its transition status under Republic Act No. 12009, the New Government Procurement Act, and its official implementing rules.
Reporting the incident does not justify publicly naming or accusing a person without adequate evidence. Use confidential, authorized channels and give investigators the underlying records.
If the report is being used against you in court
Obtain a lawyer immediately if the receiving report is attached to a complaint, demand, collection case, administrative charge, or other formal proceeding.
Under the Rules of Civil Procedure, a party relying on an “actionable document” may allege its substance and attach it to the pleading. A party disputing its genuineness and due execution may need to make a specific denial under oath, subject to the rule’s exceptions. A casual or general denial may be inadequate. The Supreme Court has explained
Quick answer
Immediately deny the signature in writing, stop the report from being used for payment or inventory clearance, and preserve the original document and related records. Notify the organization’s authorized records custodian, finance or accounting unit, internal audit, and management. If the report has already been used—or may be used—to obtain payment, conceal a shortage, transfer accountability, or implicate you, consult a Philippine lawyer and consider filing a sworn complaint with the proper prosecutor’s office or law-enforcement agency.
Do not alter, annotate, staple, or write on the questioned original. Do not accuse a specific person publicly unless the evidence supports it. A copied signature, unexplained resemblance, or unauthorized use of a signature image may be important evidence, but whether a crime occurred depends on the document’s nature, who made or used it, the surrounding transaction, and proof of intent.
Act before the report is relied on
Send a dated written notice as soon as possible. Address it to the people who control the record or transaction, such as the records custodian, warehouse or property officer, accounting department, finance head, internal auditor, compliance officer, or company lawyer.
Your notice should:
- Identify the report by date, report number, purchase order, supplier, items, amount, and location.
- State plainly: “I did not sign this document, authorize anyone to sign for me, or approve the use of my signature.”
- Clarify whether you received, inspected, counted, or accepted any of the listed goods.
- Request an immediate hold on payment, inventory posting, property transfer, disposal, reimbursement, or clearance based on the report.
- Ask that the original and all related paper and electronic records be preserved.
- Request written confirmation of the corrective action taken.
- Reserve your right to submit further evidence or take legal action.
Send the notice through a traceable channel. Keep the sent email with full headers, receiving copy, courier proof, ticket number, or acknowledgment. If management asks you to sign a replacement report, do so only if it truthfully reflects what you personally verified. Never backdate it.
Preserve the evidence
The questioned report is only one part of the evidence. Preserve records that can establish what happened before, during, and after the supposed receipt.
The questioned document
Secure, or formally request preservation of:
- The original inventory receiving report and every copy or scanned version.
- Earlier drafts, corrected versions, and attachments.
- The document number, barcode, QR code, page count, and printing details.
- The file’s metadata, version history, audit trail, and access logs.
- The email, messaging thread, shared-drive link, workflow notification, or system entry through which it was created or circulated.
If the organization retains the original, request a clear certified or authenticated copy and written confirmation of who has custody. Photograph the document as found, including all pages and attachments, but do not treat a photograph as a substitute for preserving the original.
Transaction and inventory records
Preserve the corresponding:
- Purchase order, contract, delivery receipt, invoice, inspection report, acceptance report, stock card, property acknowledgment, payment voucher, and check or bank-transfer record.
- Gate log, warehouse logbook, receiving schedule, vehicle record, visitor record, and delivery photographs.
- Inventory-system entries showing the user account, date, time, and changes made.
- CCTV footage, especially because retention periods may be short.
- Messages involving the supplier, courier, warehouse staff, inspector, approver, and accounting personnel.
- Records of shortages, substitutions, rejected deliveries, partial deliveries, or later returns.
Ask the custodian to preserve native electronic files—not merely screenshots—and to suspend routine deletion where possible.
Genuine signature samples
Collect contemporaneous documents bearing signatures that you admit are genuine, preferably originals made around the same period. Examples include acknowledged employment records, bank documents, government forms, contracts, or routinely signed receiving records.
Do not create repeated “sample signatures” on your own initiative or write beside the questioned signature. A lawyer or qualified examiner can advise what comparison material is appropriate. Philippine courts assess handwriting through admissible evidence; resemblance alone does not automatically establish who wrote a signature.
Your personal timeline
While events are fresh, record:
- When and how you discovered the report.
- Where you were on the stated receipt date.
- Whether you had authority to receive or approve the goods.
- Who had access to your signature, signature stamp, scanned signature, account, password, device, or forms.
- Every person you notified and their response.
- Any threatened payment, deduction, disciplinary action, audit finding, or demand connected to the report.
Keep facts separate from suspicions. Identify the source of each fact and preserve supporting records.
Why the document’s classification matters
Philippine law does not assign every falsified workplace document to the same offense.
Under Articles 171 and 172 of the Revised Penal Code, as amended by Republic Act No. 10951, prohibited acts include counterfeiting or imitating a handwriting, signature, or rubric and making it appear that a person participated in an act when that person did not.
The possible classification may include:
- Falsification by a public officer or employee under Article 171. This may apply when a public officer or employee takes advantage of an official position to falsify a document.
- Falsification of a public, official, or commercial document by a private individual under Article 172(1). This may apply even if the maker is not a public officer.
- Falsification of a private document under Article 172(2). For this form, damage to another person—or intent to cause such damage—is an additional element.
- Knowing use of a falsified document under Article 172(3). Liability may arise from knowingly introducing or using a falsified document under the circumstances specified in the law, even if the user did not personally forge the signature.
A document created inside a private business is not automatically a “commercial document,” and a government-related document is not automatically “official” for every legal purpose. Courts examine the document’s nature, purpose, legal effect, and connection to official duties or commercial transactions. The Supreme Court has also emphasized that damage or intent to cause damage is required for falsification of a private document, but not in the same way for public or commercial documents. See the Revised Penal Code provisions as amended by Republic Act No. 10951 and the Supreme Court’s discussion in Typoco Jr. v. People.
If the report was used to obtain money or property through deceit, prosecutors may also examine whether another offense, such as estafa, is supported. That is not automatic: the charging theory depends on the precise acts, timing, documents, financial loss, and relationship between the alleged offenses.
Report the incident internally—but protect the investigation
An internal report can stop loss and create a prompt record of your denial. Ask the organization to:
- Place the transaction and related payments on hold.
- Restrict further access to the questioned record.
- preserve originals, system logs, emails, CCTV, and device records.
- Conduct an inventory recount and physical inspection.
- Obtain written accounts from people involved in receiving, inspection, approval, and payment.
- Record every transfer of the original document.
- Correct systems only through traceable adjusting entries—not by deleting the disputed entry.
- Give you a written copy of any finding that directly attributes receipt or approval to you.
Internal investigators should avoid circulating signature specimens more widely than necessary. They should also avoid interviewing all witnesses together, allowing records to be overwritten, or asking a suspected person to surrender evidence without a preservation plan.
An internal investigation does not necessarily replace a criminal complaint, civil remedy, audit referral, or prompt response to a court case.
When and where to seek formal help
Police, NBI, and the prosecutor’s office
You may bring the matter to the Philippine National Police or National Bureau of Investigation for investigation. A criminal complaint may also be filed with the Office of the City or Provincial Prosecutor that has proper territorial jurisdiction. Venue and jurisdiction depend on where legally significant acts occurred, not simply where you discovered the report.
A complaint should ordinarily be supported by a clear complaint-affidavit or sworn statement, witness affidavits when available, and legible copies of the relevant documents. The prosecutor determines the appropriate offense and whether the governing evidentiary standard for filing a case is met. Current filing requirements should be confirmed with the receiving prosecutor’s office; the Department of Justice publishes its guidance for filing a complaint for preliminary investigation and official forms.
Bring an organized evidence index and retain a complete duplicate set. Do not surrender your only copy without obtaining a receipt identifying every item submitted.
If government property or funds are involved
If the report concerns a government delivery, public funds, or government property, promptly notify the agency’s head or authorized representative, accounting or property unit, internal audit service, and resident Commission on Audit auditor, as appropriate. If the facts indicate misconduct by a public officer, counsel can assess whether a complaint to the Office of the Ombudsman is proper.
Government procurement is now governed by Republic Act No. 12009 and its implementing rules, subject to applicable transition provisions. The relevant official materials are available from the Government Procurement Policy Board and in the official text of Republic Act No. 12009. Procurement rules do not replace the Revised Penal Code’s requirements for proving falsification.
If you receive a demand, audit charge, disciplinary notice, or court pleading
Obtain legal advice immediately. Do not ignore a document that relies on the forged report.
If a civil complaint treats the report as an actionable document, the Rules of Civil Procedure may require a specific denial under oath of its genuineness and due execution. A casual denial or general statement may be inadequate. The exact response and deadline depend on the pleading, how and when it was served, and the applicable procedure. The Supreme Court explains the importance of a sworn, specific denial in G.R. No. 187487.
For an employment investigation, submit a factual written explanation with attachments and ask for the evidence against you. Observe the stated response deadline without giving up your right to supplement the record or obtain counsel.
Do not wait for the limitation period
The proper prescriptive period depends on the offense ultimately charged. As a general guide, an offense punishable by a correctional penalty ordinarily prescribes in 10 years, while one punishable by an afflictive penalty ordinarily prescribes in 15 years under Article 90 of the Revised Penal Code. Article 91 contains rules on when prescription begins and is interrupted.
Those rules can produce difficult disputes over discovery, concealment, the document’s classification, the accused’s absence, and what filing interrupted prescription. Evidence may disappear much sooner than the legal period expires. Report the matter promptly and obtain case-specific advice rather than calculating a last filing date yourself.
Common mistakes to avoid
- Writing “forged” across the original or placing your own signature beside it.
- Allowing the questioned report to be destroyed after a replacement is issued.
- Accepting an oral promise that the record will be corrected.
- Sending accusations through group chats or social media.
- Naming a suspected forger without evidence of authorship or knowing use.
- Focusing only on handwriting while ignoring system logs, access records, CCTV, and the underlying delivery.
- Providing your only original genuine-signature specimens to an investigator without an inventory and receipt.
- Signing a backdated correction, waiver, affidavit of desistance, or settlement without advice.
- Assuming an internal finding automatically proves or disproves criminal liability.
- Waiting until payment is released, an audit disallowance is issued, or a case is filed against you.
When legal help is urgent
Consult a Philippine lawyer promptly if:
- Payment, reimbursement, inventory clearance, or transfer of public funds is imminent.
- You are being blamed for missing, defective, or undelivered items.
- Your salary, benefits, bond, clearance, or employment is threatened.
- You received a subpoena, demand letter, notice to explain, audit observation, charge, complaint, or summons.
- The report involves government procurement, accountable property, regulated goods, or a substantial amount.
- Someone is pressuring you to confirm, replace, backdate, withdraw, or destroy the document.
- CCTV, system logs, or other evidence may soon be overwritten.
- The suspected person controls the records or investigation.
- Your digital signature, account, password, or identity documents may also have been compromised.
- Retaliation, intimidation, or evidence tampering is occurring.
Frequently asked questions
Is a forged signature automatically enough for a criminal conviction?
No. The prosecution must prove every element of the specific offense beyond reasonable doubt, including the legally relevant act of falsification and the accused’s participation. For a private document, damage or intent to cause damage is also required under Article 172(2). The document’s appearance alone may not establish who made or knowingly used it.
What if the goods were actually delivered?
Actual delivery does not authorize another person to sign your name. It may, however, affect proof of damage, intent, the report’s truthfulness, and the proper charge. State separately whether the goods arrived and whether you personally received, inspected, or accepted them.
What if a coworker says the signature was placed only to complete paperwork?
An administrative convenience is not automatic authority to sign another person’s name. The full context still matters, including any express authorization, established signing protocol, notation such as “for” or “by authority of,” intent, document type, and subsequent use.
Can I demand that the report be deleted?
Request that reliance on it be suspended and records corrected through a traceable process. Do not demand destruction of the questioned document. The original, audit trail, and correction history may be essential evidence.
Should I obtain a handwriting expert immediately?
Preserve the original and genuine comparison material first. A lawyer or investigating authority can help determine whether forensic examination is necessary and how to maintain custody and admissibility. Handwriting evidence may be useful, but access logs, witness testimony, printing records, and proof of knowing use can be equally important.
Can I settle the matter privately?
A correction, repayment, or employment settlement may address some consequences but does not necessarily erase criminal liability or bind the State. Do not sign a waiver, release, or affidavit of desistance without understanding its scope and effect.
What if the signature was copied electronically?
Preserve the native file, email headers, audit logs, account activity, device information, and source image of the signature. Philippine law recognizes electronic documents and signatures, but legal effect and attribution depend on the circumstances and proof. The governing statute is the Electronic Commerce Act, Republic Act No. 8792.
