Legal Steps When Signature Is Forged Philippines

A field-ready playbook for victims, counsel, banks, notaries, and registries on what to do the moment you discover a forged signature, how to preserve proof, what criminal, civil, and administrative remedies exist, and how to undo transactions tainted by forgery.

This is general legal information. Apply to your facts with counsel.

1) What “forgery” means in Philippine law

  • Criminal: Forgery is commonly prosecuted as Falsification (of public, official, or private documents) and/or Use of Falsified Documents under the Revised Penal Code, sometimes together with Estafa if the forgery was used to obtain money/property.
  • Civil: A document with a forged signature is void as to the person whose signature was forged. Any transfer or obligation resting on that forged signature can be annulled.
  • Notarial: A notarized document has a presumption of regularity, but notarial acknowledgment does not cure a forgery. If your signature was forged, the notarized document can be invalidated and the notary may face administrative sanctions.

2) First 72 hours: Immediate containment

  1. Freeze the situation

    • Banking/finance: Notify the bank/issuer in writing (branch + head office consumer care). Request account freeze or stop-payment on the specific instrument; dispute the transaction as forged/unauthorized.
    • Property & registries: If a land transfer is involved, file an Adverse Claim or Notice of Lis Pendens with the Registry of Deeds to warn third parties; inform the assessor and HOA/condo admin.
    • Corporate: Alert the SEC company filings portal/corporate secretary to contest forged board/shareholder resolutions.

  2. Create a paper trail

    • Execute an Affidavit of Forgery detailing dates, how you learned of it, and why the signature is not yours; attach specimen signatures.
    • Police blotter for the incident, then keep the blotter copy.

  3. Preserve evidence

    • Secure originals of the questioned document and everything attached (envelopes, receipts, notarization page, thumbprint pages).
    • Request certified copies from the custodian (bank, ROD, notary’s protocol book, company file).
    • Keep exemplars: your IDs and documents bearing genuine signatures (across time).

3) Forensic backbone: Proving the forgery

  • Expert exam: Have the document examined by the NBI Questioned Documents unit or an independent forensic document examiner. Provide standards (at least 10–20 genuine signatures over time) and the original questioned document if possible; photocopies are weaker.
  • Chain of custody: Log who handled the original from seizure to exam.
  • Other corroboration: CCTV, access logs, geolocation (transport receipts), email headers, and notary’s Notarial Register (to test if you ever appeared).

4) Banking & negotiable instruments

  • Drawer’s signature forged on a check: The drawee bank generally cannot charge the drawer’s account for a forged drawer signature (subject to defenses like the customer’s negligence and notice periods in the deposit agreement).

  • Forged indorsement: Liability may shift among collecting bank, indorsers, and drawee depending on warranties and whose customer presented the item.

  • Action items:

    • File a written forgery dispute with the bank, attach your Affidavit of Forgery, specimen signatures, and proof of non-participation (travel, hospital records, etc.).
    • Ask for provisional credit pending investigation and the bank’s final resolution letter.
    • If the bank resists, escalate through its consumer assistance ladder, then pursue regulatory complaint and/or civil action for recovery and damages.

5) Real property, titles, and notarized deeds

  • Forged Deed of Sale/Donation/Mortgage: A deed with a forged owner’s signature is void; the forger conveys nothing.

  • Title already transferred? You may seek:

    • Reconveyance and cancellation of title;
    • Annulment of deed for forgery;
    • Injunction/TRO to stop further disposition;
    • Adverse Claim (quick annotation) and/or Lis Pendens (if an action is filed).

  • Innocent purchaser for value: If title already went to an innocent third party, the fight may shift to damages against the forger, the notary, and other negligent actors.

  • Notary exposure: File an administrative complaint against the notary public (for failing to verify identity/appearance), potentially with IBP and the Executive Judge who commissioned the notary.

6) Corporate & commercial documents

  • Forged board/shareholder resolutions, SPA, or guarantees: Treat them as void as to you; notify counterparties in writing; demand that corporate filings not be accepted or be withdrawn; seek injunctive relief if the forgery enables bank borrowings or asset transfers.
  • Employment/HR: Forged resignations, payroll authorizations, or waivers are ineffective; lodge an internal protest, preserve email and HRIS logs, and consider labor action for illegal dismissal if the forgery was used to terminate you.

7) Criminal, civil, and administrative remedies (how they fit together)

A) Criminal complaint (Prosecutor’s Office)

  • Crimes: Falsification (public/official/private document), Use of Falsified Document, Estafa (if deceit caused damage), and related offenses (e.g., perjury if false sworn statements were used).
  • What to file: Complaint-Affidavit, Affidavit of Forgery, expert preliminary report (if available), supporting documents, and IDs.
  • Targets: Forger, beneficiaries of the forged document, complicit notary, and accomplices (if evidence supports).

B) Civil action (RTC/MTC depending on amounts/subject)

  • Causes of action: Annulment of document/contract, reconveyance/quieting of title, rescission, damages (actual, moral, exemplary), injunction.
  • Interim relief: TRO/preliminary injunction, writ of replevin for chattel, notice of lis pendens for land.
  • Burden: Preponderance of evidence; expert findings are persuasive but courts look at totality.

C) Administrative actions

  • Notaries: Complaint before the Executive Judge (revocation/suspension of commission) and IBP (discipline).
  • Public officers: Administrative complaint if the forgery involved official records.
  • Banks/issuers: Use their consumer complaint channels; preserve the outcome letters for court/regulatory escalation.

You may run criminal and civil cases in parallel. Interim measures (adverse claim, TRO) protect property while cases proceed.

8) Evidence bundles (what wins)

  • Questioned document (original) + certified copies;
  • Signature standards (IDs, passports, earlier contracts, bank signature cards, tax forms);
  • Context proof (travel, hospital confinement, timesheets, CCTV, access logs) showing you could not have signed;
  • Notary records (Notarial Register entry, IDs presented, jurat/acknowledgment details);
  • Communications (emails, chats) showing the other party knew or facilitated the forgery;
  • Bank logs (teller approvals, CCTV at branch, instrument images);
  • Forensic report or examiner testimony.

9) Special defenses and pitfalls (anticipate them)

  • “You ratified it.” If you later accepted benefits with knowledge of the forgery, the other side may claim ratification. Avoid conduct that looks like approval; object in writing immediately.
  • Delay: Some claims are subject to prescriptive periods; act promptly to avoid laches.
  • Comparative negligence: Banks/parties may blame your carelessness (leaving signed blanks, sharing e-sign credentials). Document your reasonable care.
  • Notary “regularity”: The presumption from notarization is rebuttable by clear and convincing evidence—your non-appearance + notary’s defective records are powerful.

10) Playbooks by scenario

A) Forged bank transaction/loan

  1. Write bank: contest the transaction, attach Affidavit of Forgery + IDs + timeline.
  2. Ask for: freeze, instrument images, CCTV, audit trail, and final resolution letter.
  3. If unresolved: regulatory complaint and civil suit (damages + interest); consider criminal vs. forger.

B) Forged deed and title transfer

  1. File Adverse Claim/Lis Pendens; pull certified title history.
  2. Lodge criminal for falsification & use of falsified documents.
  3. File civil for annulment/reconveyance + injunction.
  4. Notary complaint with Notarial Register audit.

C) Forged SPA/board resolution used to sell corporate assets

  1. Board meets (quorum) and disowns the resolution in board minutes.
  2. Send cease-and-desist letters to buyers/registries/banks.
  3. Seek injunction; file criminal + civil.

D) Forged resignation/HR waiver

  1. Write HR repudiating the document; request copies of the original and audit logs.
  2. File illegal dismissal and criminal if needed; preserve e-mails and swipe logs showing you did not appear before a notary.

11) Templates (short, adaptable)

A) Affidavit of Forgery

I, [Name], of legal age, state:
1) On [date], I discovered a document titled “[title]” bearing what purports to be my
   signature dated [date]. I did not sign this document nor authorize anyone to sign for me.
2) I was at [location/event] on [date/time], making it impossible for me to have appeared
   before [Notary/Bank] as the document claims.
3) Attached are my government IDs and prior genuine signatures for comparison.
4) I execute this for filing with [bank/ROD/prosecutor] and other lawful purposes.

[Signature] [Date]

B) Bank Dispute Letter (Forgery)

Subject: Dispute – Forged Signature on [Instrument/Account]

and audit trail, and (3) issue a written resolution within [X] days.

[Name][Contact]

C) Registry Adverse Claim (Land)

ADVERSE CLAIM (PD 1529 Sec. 70)

Claimant: [Name, address]
Owner’s Duplicate TCT/CCT No. [__]
Ground: A forged [Deed] dated [__] was used to effect transfer/encumbrance. I
repudiate the signature and am filing for annulment/reconveyance.
Relief: Annotate this Adverse Claim to protect my title pending resolution.

[Signature] [Date]

D) Complaint-Affidavit (Skeleton)

Offenses: Falsification of [public/private] document; Use of Falsified Document; Estafa.

Facts: (1) Describe the questioned document and dates; (2) State non-participation and
impossibility; (3) Identify acts of respondents; (4) Damage suffered.

Annexes: Questioned document (original/certified); Affidavit of Forgery; expert prelim
report; IDs; title history/bank logs; communications; Notarial Register extracts.

12) Litigation strategy notes

  • Sequence matters: Seek interim protection (adverse claim/TRO) before the other side conveys assets away.
  • Burden framing: In criminal cases, push non-appearance and forensic variance; in civil, stress voidness ab initio and lack of consent.
  • Witnesses: Notary’s staff, bank tellers, building guards, and CCTV custodians are often decisive.
  • Settlement: If the counterparty is innocent and returns the property/money promptly, consider settlements that reverse the transaction plus reasonable damages, then withdraw criminal “use” counts—but pursue the forger.

13) FAQs

Is a photocopy enough to prove forgery? It helps but the original is best for forensic exam; still file your case and subpoena the original from the custodian.

Do I need expert testimony? It’s highly persuasive in both criminal and civil cases, but courts can also rely on other proof (e.g., alibi of non-appearance, defective notarial record).

Can a notarized deed with my forged signature still be voided? Yes. Notarization does not validate a forged signature.

How long do I have to sue? Different prescriptive periods apply to crimes and civil actions—act promptly to avoid defenses of prescription/laches.

What if the bank blames me for negligence? Show your ordinary care (no pre-signed blanks, kept checks secure, reported quickly). Banks also owe ordinary/banking diligence.

14) Bottom line

  1. Move fast: freeze accounts, annotate titles, and paper your Affidavit of Forgery.
  2. Prove it: original questioned document + exemplars + forensic exam + context proof.
  3. Hit all fronts: criminal (falsification/use/estafa), civil (annulment/reconveyance/damages), administrative (notary/bank/registries).
  4. Protect the asset today (adverse claim/TRO), litigate tomorrow.

If you share the type of document (check, deed, SPA, corporate resolution), dates, and where it’s filed/used (bank, ROD, HR), I can tailor a priority action map and fill your affidavit/demand letters in minutes.
