A perjury case in the Philippines is not established simply because someone lied, changed their story, or filed an affidavit that was later rejected. The false statement must have been made under oath, must concern an important fact, and must have been asserted knowingly and deliberately for a legal purpose. This distinction matters because the present penalty for perjury can reach ten years of imprisonment, yet weak complaints are still commonly dismissed for failing to prove materiality, intent, proper administration of the oath, or the actual falsity of the statement.

What Is Perjury Under Philippine Law?

Perjury is punished under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594 of 2021. It covers a person who knowingly makes an untruthful statement under oath, or executes a false affidavit concerning a material matter, before someone legally authorized to administer an oath, when the sworn statement is required by law or made for a legal purpose.

The law applies to both an oath and a solemn affirmation, which is a formal declaration used by someone who does not wish to take a religious oath.

Common documents that may become the subject of a perjury case include:

Complaint-affidavits and counter-affidavits filed with a prosecutor
Sworn statements submitted to the police, National Bureau of Investigation, or a government agency
Certifications against forum shopping
Verified petitions, answers, and other sworn pleadings
Sworn declarations in property, inheritance, family, corporate, tax, or immigration matters
Affidavits of loss, ownership, support, income, residency, or non-pendency of another case
Sworn corporate filings, including documents submitted to the Securities and Exchange Commission

An ordinary lie in a conversation, text message, email, Facebook post, or unsworn letter is generally not perjury. Depending on the circumstances, it may create liability under another law, but Article 183 requires a legally significant oath or affirmation.

Perjury versus false testimony in court

The Revised Penal Code treats different forms of lying under oath separately:

Conduct	Possible legal provision
Lying as a witness against an accused in a criminal trial	Article 180
Giving false testimony favorable to an accused	Article 181
Giving false testimony in a civil case	Article 182
Making a false affidavit or other sworn statement for a legal purpose	Article 183
Knowingly offering a false witness or false testimony in an official proceeding	Article 184

A person who lies while actually testifying in court may therefore be prosecuted for false testimony, rather than ordinary perjury. A false complaint-affidavit, certification, or verified pleading can fall under Article 183.

Elements of Perjury in the Philippines

The prosecution must prove all four elements beyond reasonable doubt.

Element	What must be shown
1. A sworn statement on a material matter	The accused testified under oath or signed an affidavit concerning an important fact
2. A competent officer	The oath was administered by a notary public, prosecutor, judge, consular officer, or another legally authorized person
3. A willful and deliberate falsehood	The accused knew the statement was false and intentionally presented it as true
4. A legal requirement or purpose	The statement was required by law or executed for use in a legal, judicial, administrative, or official matter

These elements have repeatedly been applied by the Supreme Court, including in Saulo v. People, G.R. No. 242900, June 8, 2020. (Supreme Court E-Library)

1. The statement must concern a material matter

A material matter is an important fact connected with the issue being investigated or decided. It may be:

The main fact under inquiry
A fact that tends to prove or disprove the main issue
A circumstance that strengthens or weakens relevant evidence
A fact affecting the credibility of a witness

Materiality is assessed by the statement’s capacity to influence the proceeding. The complainant does not always have to prove that the prosecutor, judge, or agency actually believed the lie or decided the case because of it. Its potential to affect the decision can be enough. (Supreme Court E-Library)

For example, falsely stating in a complaint-affidavit that a person stole company checks is material because it may influence a prosecutor’s determination of probable cause. By contrast, an incorrect description of an irrelevant detail that could not affect the inquiry may not satisfy this element.

2. The oath must be administered by an authorized person

The prosecution must establish that the accused actually swore to the truth of the statement before a competent officer.

Authorized persons commonly include:

A commissioned notary public acting within the territorial limits of the commission
A prosecutor receiving affidavits for preliminary investigation
A judge or other judicial officer authorized by law
A Philippine consular officer performing notarial functions abroad
Certain government officers specifically authorized to administer oaths

A jurat stating “subscribed and sworn to before me” is important evidence, but the surrounding facts may still be examined. Philippine notarial rules generally require the affiant to appear personally and present competent proof of identity. A notary should not notarize a document signed by someone who never appeared before the notary. (Lawphil)

A defective notarization does not automatically prove that the affiant committed perjury. It may instead raise separate issues concerning forgery, falsification, the authenticity of the signature, or the notary’s administrative liability.

3. The falsehood must be willful and deliberate

This is often the most difficult element to prove.

The prosecution must show more than an inaccurate statement. It must establish that the accused:

Knew the statement was false, or was consciously asserting it despite knowing there was no truthful basis;
Intentionally represented the statement as true; and
Did not make the statement merely because of mistake, confusion, faulty memory, misunderstanding, or poor wording.

The Supreme Court has explained that “willful” means intentional and made with consciousness of the falsity, while “deliberate” distinguishes a considered falsehood from an inadvertent error. Perjury is a felony committed by dolo, meaning criminal intent or malice must be present. (Supreme Court E-Library)

Evidence of intent may include:

Documents showing the accused personally knew the true facts
Emails or messages discussing a plan to make the false allegation
Prior admissions inconsistent with the sworn claim
Financial, corporate, property, or government records in the accused’s possession
Attempts to conceal, alter, or fabricate supporting documents
The timing of the affidavit, particularly when it follows a demand, dispute, or threatened case
Testimony from neutral witnesses who directly observed the relevant events

Motive can support the case, but motive alone does not prove perjury.

4. The affidavit must be required by law or made for a legal purpose

Not every notarized statement is covered by Article 183. The oath must have a genuine legal or official purpose.

A complaint-affidavit filed to begin a criminal investigation plainly has a legal purpose. The same may be true of a verified court pleading, sworn government application, certification against forum shopping, or affidavit required to register or transfer a right.

A privately notarized statement prepared only to embarrass another person, with no real legal use, may fail this element even if it contains lies.

What Evidence Is Needed to Prove Perjury?

A well-prepared complaint should prove each element separately. Merely attaching the disputed affidavit and saying “this is a lie” is rarely enough.

The disputed sworn statement

Obtain the best available version of the document:

The original, when available
A certified true copy from the court, prosecutor, agency, or records custodian
The complete document, including annexes, signature page, jurat, notarial details, filing stamp, and docket information
Proof of when and where it was executed and filed

Screenshots or photocopies may help initially, but authenticated or certified records carry much greater evidentiary value.

Proof that the statement is false

Use evidence independent of the accused’s inconsistent statements, such as:

PSA birth, marriage, or death certificates
Land titles, tax declarations, deeds, and Registry of Deeds records
Bank records, receipts, checks, ledgers, and audited financial documents
SEC filings and corporate books
Government certifications
Employment, payroll, immigration, or travel records
Photographs, videos, electronic records, and metadata
Testimony from witnesses with personal knowledge

In Masangkay v. People, G.R. No. 164443, June 18, 2010, the Supreme Court emphasized that contradictory sworn statements do not, by themselves, establish which statement is false. The prosecution must present evidence aliunde, meaning independent evidence outside the conflicting declarations, to prove the falsity charged. (Supreme Court E-Library)

This means there is no automatic perjury case merely because a person gave two different sworn versions. One statement may be false, but the prosecution must prove which one.

Proof of knowledge and intent

Intent is usually established through circumstances rather than a direct admission. Strong evidence may show that the accused:

Signed or personally created records proving the opposite of the sworn statement
Participated directly in the transaction later denied
Received letters, payments, notices, or documents confirming the true facts
Repeated the false statement after being shown conclusive contrary evidence
Fabricated supporting documents or instructed witnesses to support the story

Proof of the oath and the officer’s authority

Useful records include:

The complete jurat
The notary’s commission details
The notarial register entry
Testimony or certification from the notary, prosecutor, or records officer
The official receiving copy showing that the document was sworn and filed

How to File a Perjury Complaint in the Philippines

Because the current penalty exceeds four years, two months, and one day, a preliminary investigation is required under Rule 112 of the Rules of Criminal Procedure. (Lawphil)

1. Identify the exact false statement

Quote the precise sentence or paragraph alleged to be false. Avoid attacking the entire affidavit in general terms.

For each statement, explain:

What the accused said under oath
What the true fact is
Why the statement was material
What evidence proves it was false
Why the accused knew the truth

2. Determine the proper venue

Criminal cases must generally be filed where the offense, or an essential element of it, occurred under Section 15 of Rule 110. (Lawphil)

For an affidavit-based perjury case, relevant places may include:

Where the accused appeared and swore before the authorized officer
Where the affidavit was executed
Where an essential act completing the offense occurred

The place where the document was later submitted is not automatically the proper venue in every case. Venue should be assessed from the actual allegations and the acts constituting the offense.

3. Prepare the complaint-affidavit

The complaint-affidavit should contain:

The complainant’s complete identity and address
The respondent’s known identity and address
The date and place of execution of the disputed affidavit
The authorized officer who administered the oath
The exact material falsehood
The true facts and supporting evidence
Facts showing deliberate knowledge and intent
A list of annexes
A request that the respondent be prosecuted under Article 183

Witnesses should ordinarily execute their own affidavits based on personal knowledge. Avoid having one witness merely repeat what another person said.

4. Attach organized supporting documents

Label annexes consistently, such as Annex “A,” “B,” and “C.” If a document has many pages, identify the particular page and paragraph that matter.

An effective evidence index may look like this:

Annex	Document	Purpose
A	Certified copy of disputed affidavit	Proves the sworn statement
B	Jurat or notarial record	Proves oath and competent officer
C	Official certification	Proves the true fact
D	Contract, receipt, or bank record	Independently disproves the statement
E	Witness affidavit	Establishes personal knowledge
F	Messages or correspondence	Shows knowledge and intent

5. File with the proper prosecutor’s office

The complaint is usually filed with the Office of the City Prosecutor or Office of the Provincial Prosecutor having territorial jurisdiction.

Barangay conciliation is generally not a prerequisite because the present penalty for perjury exceeds the one-year imprisonment limit for disputes covered by the Katarungang Pambarangay system under Section 408 of the Local Government Code.

The prosecutor’s office ordinarily does not impose a court docket fee for filing a criminal complaint. Expenses commonly arise from:

Certified copies
Notarization
Printing and photocopying
Courier or personal service
Translation and authentication of foreign records
Legal representation

Local offices may require several paper copies and a digital copy. Filing requirements can differ by city or province.

6. Participate in the preliminary investigation

Under Rule 112:

The prosecutor conducts an initial evaluation and may dismiss a plainly insufficient complaint or issue a subpoena.
The respondent normally has 10 days from receipt of the subpoena to submit a counter-affidavit and supporting evidence.
If the respondent does not answer despite proper service, the prosecutor may resolve the case using the complainant’s evidence.
The prosecutor may hold a clarificatory hearing, but the parties do not have an ordinary right to cross-examine each other at this stage.
The prosecutor determines whether there is probable cause to file an Information in court. (Supreme Court E-Library)

The Rules contain short internal periods, but actual proceedings often take several months. Delays commonly result from unsuccessful service of subpoenas, requests for extensions, voluminous records, changes in prosecutor assignments, motions for reconsideration, and office backlogs.

7. Court proceedings after a finding of probable cause

For perjury committed under the present law, the maximum prescribed imprisonment exceeds six years. Original jurisdiction therefore generally belongs to the Regional Trial Court, rather than the first-level MTC, MeTC, MTCC, or MCTC. (Lawphil)

After the Information is filed:

The judge independently evaluates probable cause.
The court may dismiss the case, require additional evidence, or issue a warrant of arrest.
The accused may post bail, subject to the court’s order.
Arraignment, pretrial, trial, judgment, and possible appeal follow.

A prosecutor’s finding of probable cause is not a conviction. At trial, every element must still be established beyond reasonable doubt.

Penalty for Perjury in the Philippines

Under the enrolled text of RA 11594, perjury is punishable by prision mayor in its minimum period to prision mayor in its medium period, equivalent to imprisonment ranging from six years and one day to ten years. If the offender is a public officer or employee, the law directs the court to impose the prescribed penalty in its maximum period.

The law also provides:

A fine not exceeding ₱1,000,000
Perpetual absolute disqualification from holding an appointive or elective government position

Because perjury is not punishable by reclusion perpetua, an accused is generally entitled to bail as a matter of right before conviction, although the court determines the amount and conditions.

Older affidavits may be governed by the previous penalty

Penal laws imposing a heavier punishment generally operate prospectively. A statement made before the effectivity of RA 11594 may be governed by the previous, more lenient version of Article 183.

The date of execution is therefore important. Prosecutors and courts should not apply the increased penalty to an act committed before the amendment took effect when doing so would prejudice the accused.

Prescription of the offense

Prision mayor is an afflictive penalty. Under Article 90 of the Revised Penal Code, offenses punishable by an afflictive penalty generally prescribe in 15 years. (Lawphil)

Prescription is not always counted through simple calendar arithmetic. The starting date, discovery of the offense, filing of proceedings, interruption of the prescriptive period, and law in force when the affidavit was executed may affect the computation.

Defenses to a Perjury Charge

A respondent should address the statutory elements rather than merely denying bad intentions.

Common defenses include:

The statement was true

A statement cannot be perjury if its essential factual assertion was true, even if it was inconvenient, incomplete, or disputed by the complainant.

The statement was not material

The alleged falsehood may have had no legitimate tendency to affect the proceeding or the credibility of relevant evidence.

There was an honest mistake

Confusion, defective memory, misunderstanding, reliance on incorrect records, ambiguity, or clerical error may negate deliberate intent.

A prompt correction can support the claim that the error was innocent, although retraction does not automatically erase an offense that was already completed.

The language was ambiguous or qualified

Words such as “approximately,” “to the best of my knowledge,” or “I believe” must be read in context. An opinion, legal conclusion, estimate, or genuinely ambiguous answer may not amount to a deliberate assertion of a false objective fact.

A person cannot deliberately use vague language to conceal a known lie, but the prosecution must still prove the exact assertion alleged to be false.

The statement was not properly sworn

The defense may question whether:

The accused actually appeared before the officer
The signature is authentic
The officer had authority to administer the oath
The oath or affirmation was actually administered
The document was altered after it was signed

The statement had no legal purpose

A privately notarized document unrelated to any legal requirement or legitimate official purpose may not satisfy Article 183.

The evidence shows only inconsistent statements

Under Masangkay, contradictory affidavits cannot alone establish which statement was false. Independent corroborating evidence is required. (Supreme Court E-Library)

Venue, prescription, or identity was not established

The prosecution must prove that the case was filed in the correct place, within the applicable prescriptive period, and against the person who actually made the sworn statement.

Remedies When a False Affidavit Is Being Used Against You

A perjury complaint is only one possible response. The underlying proceeding usually requires immediate attention because a later perjury prosecution does not automatically stop the original case.

Challenge the statement in the main proceeding

Depending on the forum, the affected person may:

File a counter-affidavit, opposition, answer, or comment
Submit certified records contradicting the statement
Ask that false or inadmissible material be disregarded
Cross-examine the witness when trial or hearing rules permit
Request production of original records
Challenge the document’s authenticity, signature, notarization, or chain of custody
Seek reconsideration or appeal from an adverse agency or court ruling

The priority is often to prevent the false statement from producing an incorrect judgment, prosecution, annotation, registration, or administrative decision.

Seek civil damages

Article 100 of the Revised Penal Code provides that a person criminally liable for a felony is also civilly liable. Under Rule 111, the civil action arising directly from the offense is generally deemed instituted with the criminal case unless it was waived, reserved, or filed separately. (Lawphil)

Depending on the facts, damages may cover proven financial loss, litigation-related injury, reputational harm, or other direct consequences of the criminal act. Separate claims under Articles 19, 20, and 21 of the Civil Code require their own factual and legal basis and should not be treated as automatic consequences of every unsuccessful affidavit or complaint.

File an administrative complaint when appropriate

Separate administrative remedies may exist when the person responsible is:

A government employee or public officer
A lawyer or commissioned notary public
A licensed professional
An employee who submitted a false sworn document in an employment investigation
A corporate officer who made a false regulatory filing

Administrative liability has a different standard and purpose from criminal perjury. Dismissal of the criminal case does not always prevent an administrative proceeding, and vice versa.

Report possible falsification or forgery

If the affidavit contains a forged signature, fabricated notarial details, altered pages, or counterfeit government certifications, the conduct may involve falsification or use of a falsified document in addition to, or instead of, perjury.

Documents, Costs, and Expected Timeline

Item	Practical detail
Disputed affidavit	Obtain an original or certified true copy, including the complete jurat and annexes
Proof of falsity	Use official records and independent evidence, not only another contradictory affidavit
Witness affidavits	Each witness should state facts personally observed
Identification	Government-issued ID or passport is normally required when executing the complaint-affidavit
Filing cost	Criminal complaints ordinarily have no court docket fee at the prosecutor level
Other expenses	Certification, notarization, authentication, translation, copying, courier, travel, and professional fees
Counter-affidavit period	Normally 10 days from receipt of the prosecutor’s subpoena
Prosecutor resolution	The Rules prescribe short periods, but actual resolution frequently takes months
Court proceedings	Trial may take years where there are multiple witnesses, postponements, or appeals

Perjury Cases Involving Foreigners or Overseas Filipinos

Nationality does not prevent a person from filing or facing a perjury case in the Philippines. The same elements apply to Filipino citizens and foreigners.

A foreign complainant will commonly need:

A valid passport or Philippine-issued identification
A reliable address for notices
Certified Philippine records or properly authenticated foreign documents
English translations of documents written in another language
A locally usable complaint-affidavit

An affidavit executed abroad may generally be:

Signed and sworn before a Philippine consular officer; or
Notarized under the law of the foreign country and apostilled by the competent authority if that country is a party to the Apostille Convention.

Documents from a non-Apostille country may require consular authentication or legalization. Requirements should be checked with the Philippine embassy or consulate responsible for the country of execution. DFA guidance confirms that qualifying apostilled foreign documents may be accepted in the Philippines without additional Philippine embassy authentication. (Philippine Embassy in New Delhi)

An apostille authenticates the origin of the public document or notarial certificate. It does not prove that every factual statement inside the affidavit is true.

Common Mistakes That Weaken Perjury Complaints

Treating the dismissal of the original complaint as automatic proof that the complainant lied
Relying only on two contradictory affidavits
Failing to quote the exact false statement
Attacking statements that are irrelevant or immaterial
Presenting speculation instead of independent records
Ignoring the requirement to prove deliberate knowledge
Filing in the wrong city or province
Submitting incomplete photocopies without the jurat or filing details
Confusing a false opinion or legal conclusion with a false factual assertion
Filing primarily as retaliation in an ongoing family, property, labor, or business dispute
Assuming that a defective notarization automatically proves perjury
Waiting too long to secure records, videos, messages, and witnesses

Frequently Asked Questions

Can I file perjury because someone lied in an affidavit?

Yes, but only if the lie concerns a material matter, was made under a valid oath before an authorized officer, was deliberate, and appeared in a statement required by law or made for a legal purpose.

Is the dismissal of a false criminal complaint enough to prove perjury?

No. Dismissal may result from insufficient evidence, procedural defects, or failure to establish probable cause. A perjury complainant must independently prove that a particular material statement was knowingly false.

Are two contradictory affidavits sufficient?

Not by themselves. The prosecution must present independent evidence showing which statement is false.

Where should a perjury complaint be filed?

It is generally filed with the city or provincial prosecutor having jurisdiction over the place where the offense or an essential element occurred. For affidavit-based cases, the place where the oath was administered is often important.

Is barangay conciliation required before filing perjury?

Generally, no. The current imprisonment prescribed for perjury exceeds the penalty limit for offenses subject to mandatory barangay conciliation.

Can a person be arrested immediately after I file the complaint?

Filing a complaint-affidavit does not ordinarily result in immediate arrest. The case first undergoes preliminary investigation. If an Information is filed, the judge independently determines whether a warrant should issue.

Can correcting or withdrawing the affidavit prevent prosecution?

Not automatically. Retraction may be relevant to intent, credibility, and damage, but it does not necessarily erase an offense already completed. A prompt, voluntary correction made before the statement is relied upon may support an honest-mistake defense.

Can a lawyer be charged for a client’s false affidavit?

A lawyer is not criminally liable merely for submitting a client’s affidavit. Liability under Article 184 or another provision would require evidence that the lawyer willfully and knowingly offered false testimony or participated in unlawful conduct. Professional disciplinary rules may also apply where a lawyer knowingly assists dishonesty or fraud.

Can a foreigner file a perjury complaint in the Philippines?

Yes. A foreigner may file if the Philippine prosecutor has jurisdiction. Affidavits and evidence executed abroad must satisfy applicable notarization, apostille, authentication, and translation requirements.

How long can a perjury case take?

Preliminary investigation commonly takes several months, although the Rules prescribe shorter periods for individual steps. A contested RTC trial may take several years, particularly where service, expert evidence, numerous witnesses, motions, or appeals are involved.

Key Takeaways

Perjury requires more than a lie: it must be a deliberate falsehood under oath concerning a material matter and made for a legal purpose.
A dismissed complaint or contradictory affidavit does not automatically prove perjury.
Independent evidence must establish which statement is false and that the accused knew it was false.
RA 11594 increased the present penalty to six years and one day up to ten years, with additional penalties provided by law.
Current perjury cases require preliminary investigation and generally fall within Regional Trial Court jurisdiction.
The underlying case should be contested directly; filing perjury does not automatically suspend or defeat the proceeding in which the false statement was used.
Certified records, proper venue, proof of the oath, and evidence of deliberate intent are usually the decisive parts of a perjury case.
