Quick answer

Philippine law provides both criminal and civil remedies when a person’s reputation is unlawfully harmed:

Libel generally covers defamatory statements published in writing, print, radio, video, or similar permanent media.
Cyber libel is libel committed through a computer system, including an original defamatory social-media post, email, website article, or online video.
Slander, also called oral defamation, covers defamatory words spoken to another person.
Slander by deed covers an act intended to cast dishonor, discredit, or contempt when the act is not already punished as another offense.

A successful case normally requires a defamatory imputation, publication to at least one person other than the victim, identification of the person defamed, and malice. Hurt feelings, criticism, profanity, or an unfavorable opinion do not automatically amount to actionable defamation.

Time is critical. Criminal libel and cyber libel generally prescribe in one year from discovery, while oral defamation and slander by deed prescribe in six months from discovery. A civil action for defamation generally must also be filed within one year, although its accrual and any interruption of prescription require a fact-specific assessment.

What must be proved

Article 353 of the Revised Penal Code defines a defamatory imputation broadly. It may involve an accusation of:

A crime;
A vice or defect, whether real or imaginary;
An act, omission, condition, status, or circumstance that tends to dishonor or discredit a person or expose that person to contempt; or
A matter that blackens the memory of someone who has died.

Courts ordinarily examine four elements:

Defamatory imputation. The statement, read or heard as a whole and in its ordinary context, must tend to damage reputation.
Publication. At least one third person must have received, read, or heard it. A message communicated only to the person being criticized ordinarily lacks this element, but a group chat, copied email, public speech, bulletin-board notice, or social-media post may satisfy it.
Identification. The complainant must be named or otherwise reasonably identifiable. A nickname, photograph, job description, surrounding facts, or references understood by readers may be enough.
Malice. As a general statutory rule, a defamatory imputation is presumed malicious unless it falls within a privilege or good intention and justifiable motive are shown.

These elements are discussed in the Supreme Court’s decision in Tulfo v. People.

A company or other juridical person can also be defamed. Conversely, a statement directed at a large or indefinite group may fail if the individual complainant cannot show that readers reasonably understood the statement to refer specifically to that person.

Libel, cyber libel, and slander are not interchangeable

Written or broadcast libel

Article 355 covers libel committed through writing, printing, engraving, radio, painting, theatrical or cinematographic exhibition, and similar means. This can include newspapers, letters shown to third persons, posters, radio or television broadcasts, and other relatively permanent publications.

Cyber libel

Section 4(c)(4) of the Cybercrime Prevention Act applies when libel is committed through a computer system or similar technology. Common examples may include an original defamatory:

Social-media post or caption;
Blog or website article;
Email sent to third persons;
Online comment containing a new accusation;
Uploaded image, recording, livestream, or video; or
Message posted in an online group.

Cyber libel is constitutional as applied to the original author of the defamatory statement. In Disini v. Secretary of Justice, the Supreme Court held that the law is unconstitutional as applied to people who merely receive a post and react to it through ordinary “Like,” “Comment,” or “Share” functions. The Court also invalidated aiding or abetting liability in relation to cyber libel.

That protection has limits. A person who adds a new defamatory accusation in a comment or repost may become the original author of that new statement. Copying content into an independently worded defamatory post can likewise present a different issue from merely clicking “Share.”

The same publication cannot ordinarily be charged both as traditional libel and cyber libel when the charges punish the same online act. The Supreme Court held in Disini that doing so would violate the prohibition against double jeopardy.

Oral defamation or slander

Article 358 covers spoken defamatory words. Courts classify oral defamation as serious or slight by considering the words used, their ordinary meaning, the parties’ relationship, the occasion, the victim’s position, and the surrounding circumstances.

The fact that insulting words were spoken during an argument may affect classification, malice, or penalty, but anger does not automatically excuse defamatory speech.

Slander by deed

Article 359 applies to a dishonoring act that is not already punished under another provision. Whether conduct constitutes serious or slight slander by deed depends on its nature, purpose, circumstances, and social significance.

Physical contact may instead constitute—or additionally raise questions about—physical injuries, coercion, unjust vexation, violence against women or children, or another offense. The proper charge must be based on the actual conduct rather than the label used by the complainant.

Truth, opinion, and privileged communications

Truth is not always enough

It is a common mistake to assume that every true statement is immune from liability. Under Articles 354 and 361, truth in a criminal libel case generally must be accompanied by good motives and justifiable ends.

Article 361 also restricts proof of the truth of an imputation involving an act or omission that is not itself a crime, unless it concerns a government employee and facts related to the discharge of official duties. Constitutional protections involving public officials and matters of public concern may change how these statutory rules apply.

Before publishing a damaging accusation, preserve reliable source documents and ask:

Is the allegation supported by admissible evidence?
Is publication reasonably necessary for a legitimate purpose?
Is the audience limited to people who need the information?
Are allegations clearly distinguished from proven facts?
Have important explanations or contrary records been omitted?

Opinion and fair comment

A pure opinion based on disclosed or established facts receives greater protection, particularly on matters of public interest. Calling something “my opinion” does not create immunity if the statement actually asserts or implies an undisclosed and provably false fact.

Fair comment concerning a public person’s public conduct may be privileged when based on established facts. An accusation built on a false factual premise, or a personal attack unrelated to public functions, may fall outside that protection.

Qualified privilege

Article 354 recognizes qualified privileges, including:

A private communication made in the performance of a legal, moral, or social duty; and
A fair and true report, made in good faith and without added comments, of a non-confidential judicial, legislative, or other official proceeding or official act.

The Supreme Court also recognizes fair commentary on matters of public interest. Qualified privilege removes the ordinary presumption of malice, but liability may still arise if actual malice is proved.

For a duty-based private communication, unnecessary distribution can defeat the purpose of the privilege. A workplace report may be defensible when sent in good faith to the responsible supervisor, but not necessarily when copied to people who have no legitimate role.

Public officials and public figures

When a statement concerns a public official’s official conduct—or a public figure and a genuine matter of public interest—the complainant ordinarily must prove actual malice: knowledge that the statement was false or reckless disregard of whether it was false.

Mere mistake, inaccuracy, or failure to prove the statement true does not by itself establish actual malice. However, public office does not erase a person’s right to privacy. An attack on private life is not automatically privileged merely because the subject holds government office.

Absolute privilege

Some statements are absolutely privileged when relevant to the protected proceeding, such as pertinent allegations in judicial pleadings and responsive testimony in court. Legislative speech protected by the Constitution is another example.

Absolute privilege is narrow. Republishing a court allegation on social media is a separate act and does not automatically inherit the privilege enjoyed by the original pleading.

Immediate steps if you have been defamed

1. Preserve the complete evidence

Do this before requesting removal or confronting the author:

Capture the complete post, conversation, page, or broadcast—not only the offensive sentence.
Record the URL, account name, profile link, date, time, privacy setting, number of reactions, and visible recipients.
Make screenshots and a screen recording showing how the material was accessed.
Save the original email, message export, audio, video, photograph, or webpage file.
Preserve headers, metadata, notification emails, and download history where available.
Identify witnesses who personally read or heard the statement and record when and how they discovered it.
Preserve proof that readers understood the statement to refer to you.
Keep records of lost clients, employment consequences, medical treatment, counseling, security expenses, or other measurable harm.
Write down the exact date when you, a representative, or authorities first discovered the publication.

Electronic evidence must be authenticated. A cropped screenshot whose account, date, context, or source cannot be verified may receive little weight. The Rules on Electronic Evidence place the burden of proving an electronic document’s authenticity on the party offering it.

Do not access another person’s account without permission, install spyware, alter files, or secretly record a private conversation without first obtaining legal advice. Evidence gathered unlawfully can create a separate criminal or privacy problem.

2. Limit further damage

Depending on the circumstances, consider:

A calm written request for correction, retraction, apology, or removal;
A platform report based on impersonation, harassment, privacy, or defamation policies;
A request that an employer, school, association, publisher, or group administrator preserve records and apply its internal rules; or
A lawyer’s demand letter proposing a correction, non-republication undertaking, or settlement.

A demand letter is not always required. It also does not automatically stop every criminal deadline. A valid written extrajudicial demand may affect prescription of a civil claim under Article 1155 of the Civil Code, but its legal effect depends on its contents, delivery, proof, and the cause of action. Do not rely on negotiations while a deadline is running.

Preserve the evidence before seeking deletion. An apology, retraction, removal, or affidavit of desistance does not automatically erase a completed offense or require a prosecutor or court to dismiss an existing criminal case.

3. Avoid a retaliatory publication

A public rebuttal can unintentionally repeat and amplify the accusation. It may also expose private information, prejudice a future case, or generate a countercharge. When a response is necessary, correct verifiable facts without adding threats, insults, or unsupported accusations.

Do not demand money in exchange for withholding a threatened defamatory publication. Article 356 separately penalizes threatening to publish a libel or offering to prevent publication for compensation.

Criminal complaint

A complainant ordinarily begins by filing a sworn complaint-affidavit and supporting evidence with the Office of the City or Provincial Prosecutor that has territorial authority. Online cases may first be investigated by the cybercrime units of the National Bureau of Investigation or Philippine National Police, which are the law-enforcement authorities designated by Section 10 of the Cybercrime Prevention Act.

The complaint should clearly establish:

The exact defamatory words, image, recording, or act;
Who authored, uttered, published, or caused it to be published;
When and where it occurred;
Who received or witnessed it;
How the complainant was identified;
Why it was defamatory and malicious;
The date and circumstances of discovery; and
Facts supporting the chosen venue.

The prosecution office applies the current DOJ-NPS investigation rules and evaluates whether the evidence is admissible, credible, capable of preservation, and sufficient to establish a prima facie case with reasonable certainty of conviction. The respondent is normally given a subpoena and an opportunity to submit a sworn counter-affidavit and supporting evidence. The specific procedure and response period depend on whether the case undergoes regular, expedited, or summary investigation; the date stated in the subpoena should be treated as controlling.

Written and cyber-libel cases are handled by Regional Trial Courts, with cyber-libel cases assigned to designated cybercrime courts where available. Oral defamation and slander-by-deed cases may follow a different prosecution and court track depending on their classification.

E-filing and virtual proceedings may be available under DOJ rules, but availability and intake requirements should be confirmed with the particular prosecution office. The DOJ’s official filing checklist for complaints identifies the usual complaint-affidavit, witness affidavits, investigation form, and supporting documents.

Anonymous online authors

A screenshot alone may not identify the person controlling an account. Subscriber, traffic, device, and platform records may require prompt law-enforcement preservation and a court-issued cybercrime warrant.

Under Sections 13 and 14 of the Cybercrime Prevention Act, service providers must preserve specified traffic data and subscriber information for at least six months from the transaction. Content data is preserved for six months from receipt of a proper law-enforcement preservation order, subject to a possible one-time extension. Disclosure generally requires a court warrant and a valid, docketed complaint.

A private demand to a platform is not a substitute for these legal processes, and overseas providers may present additional jurisdictional and retention issues.

Civil remedies

Article 33 of the Civil Code permits an independent civil action for damages arising from defamation. It may proceed separately from a criminal prosecution and is decided by preponderance of evidence, a lower standard than proof beyond reasonable doubt.

Depending on the evidence and legal basis, recoverable relief may include:

Proven actual or compensatory damages;
Moral damages for reputational injury, humiliation, anxiety, or similar harm;
Exemplary damages when the legal requirements are met;
Attorney’s fees and litigation expenses in circumstances allowed by law; and
Other appropriate relief the court has authority to grant.

Damages are not automatic. Actual financial loss should be supported by records. Moral and exemplary damages remain subject to proof, legal standards, and judicial discretion.

A lawyer should coordinate an independent civil action with any criminal case. Rule 111 generally treats civil liability arising from an offense as included with the criminal action unless it is waived, reserved where required, or separately pursued under an authorized independent cause of action. The injured person cannot recover twice for the same injury.

The Civil Code provisions commonly considered include Articles 19, 20, 21, 26, 33, and 1147. The official text is available through the Supreme Court E-Library’s Civil Code of the Philippines.

Filing deadlines

Claim	General prescriptive period	General starting point
Traditional criminal libel	1 year	Discovery by the offended party, authorities, or their agents
Criminal cyber libel	1 year	Discovery by the offended party, authorities, or their agents
Oral defamation	6 months	Discovery
Slander by deed	6 months	Discovery
Civil action for defamation	1 year	Accrual of the civil cause of action, subject to applicable interruption rules

In its April 8, 2026 final resolution in Causing v. People, the Supreme Court confirmed that cyber libel prescribes in one year, not 12 or 15 years, and that the period is reckoned from actual discovery. A public social-media post does not create an automatic presumption that the complainant discovered it on the posting date.

Under Article 91, filing the proper complaint or information interrupts criminal prescription. A private demand, platform report, police blotter entry, or informal mediation should not be assumed to have the same effect. Because venue defects and the nature of the filing can create disputes, file in the correct office well before the deadline.

For a civil claim, Article 1147 sets a one-year period for defamation. Determining accrual, interruption by a written demand, and the effect of earlier proceedings can be technical. Obtain advice immediately rather than calculating the final day without counsel.

Venue matters

Venue in criminal cases is jurisdictional. Filing in the wrong place can defeat an otherwise timely case.

For traditional written or broadcast libel, Article 360 generally permits filing in the Regional Trial Court where the material was printed and first published or, subject to its specific rules, where the offended party actually resided when the offense was committed. Special rules apply when the offended party is a public officer, including distinctions based on where the officer held office.

Cyber libel is governed by the Cybercrime Prevention Act and the Rule on Cybercrime Warrants. A designated cybercrime court may acquire jurisdiction based on where an element occurred, where a relevant part of the computer system was situated, or where legally cognizable damage occurred. “The post could be viewed everywhere” is not a safe venue allegation.

For oral defamation, the place where the words were spoken, published to a third person, or otherwise completed as an offense must be established.

If the parties reside in the same city or municipality, barangay conciliation should also be checked. Criminal defamation complaints will often fall within statutory exceptions because of the authorized imprisonment or fine, while a separately framed civil dispute may require a different analysis. Do not assume that a barangay certificate is always required—or always unnecessary.

Possible penalties

Under Republic Act No. 10951:

Offense	Statutory penalty
Libel under Article 355	Prisión correccional in its minimum and medium periods, or a fine of ₱40,000 to ₱1,200,000, or both
Serious oral defamation	Arresto mayor in its maximum period to prisión correccional in its minimum period
Slight oral defamation	Arresto menor, or a fine not exceeding ₱20,000
Serious slander by deed	Arresto mayor in its maximum period to prisión correccional in its minimum period, or a fine of ₱20,000 to ₱100,000
Slight slander by deed	Arresto menor, or a fine not exceeding ₱20,000

Section 6 of the Cybercrime Prevention Act directs that the penalty for an offense committed through information and communications technology be imposed one degree higher than the corresponding Revised Penal Code penalty.

Supreme Court Administrative Circular No. 08-2008 expresses a preference, in appropriate libel cases, for a fine instead of imprisonment. It does not remove imprisonment as an available penalty. The judge retains discretion based on the circumstances, including in cyber-libel cases.

A conviction can also involve civil damages and subsidiary consequences allowed by law. The exact sentence depends on the charge, applicable amendments, mitigating or aggravating circumstances, and sentencing rules.

If you have been accused

Do not ignore a demand letter, prosecutor’s subpoena, summons, or court notice.

Preserve the complete publication and the materials relied on when it was made.
Record the purpose, intended audience, sources, editing history, and steps taken to verify the statement.
Keep official records supporting truth, public interest, privilege, or good faith.
Do not alter screenshots, manufacture supporting records, pressure witnesses, or retaliate against the complainant.
Consult counsel before deleting the material. Removal may limit harm, but the original evidence should first be lawfully preserved.
Submit the counter-affidavit and evidence by the deadline stated in the subpoena. A motion to dismiss is generally not a substitute for the required counter-affidavit.
Examine prescription, venue, authorship, publication, identification, privilege, actual malice, and whether the statement was fact or protected opinion.

Silence, apology, or settlement may be sensible in some cases, but none should be treated as an admission or drafted without considering its effect on pending proceedings.

Common mistakes

Waiting for negotiations to finish while the one-year or six-month period expires;
Saving only a cropped screenshot without its URL, account identity, context, or date;
Assuming that truth alone is a complete defense;
Treating every insult or negative review as criminal defamation;
Naming the platform, page administrator, editor, or account owner without evidence of authorship or legal responsibility;
Filing where the post was merely accessible without establishing a valid venue;
Repeating the accusation publicly in an emotional rebuttal;
Obtaining evidence by hacking an account or unlawfully recording a conversation;
Assuming a deletion, apology, settlement, or affidavit of desistance automatically ends a criminal case; and
Assuming that a simple “Like” or “Share” and a new, independently defamatory comment have the same legal effect.

When legal help is urgent

Seek a Philippine lawyer immediately when:

A one-year or six-month deadline may be approaching;
The author is anonymous or the content may disappear;
You need subscriber or platform records preserved;
The publication is causing immediate employment, business, professional, or safety consequences;
A child, intimate image, doxxing, stalking, impersonation, extortion, or threat is involved;
You have received a prosecutor’s subpoena, arrest warrant, search warrant, or court summons;
The statement concerns a public official, election, judicial proceeding, confidential complaint, workplace investigation, or media report; or
Criminal and independent civil proceedings are being considered together.

Threats, extortion, unlawful disclosure of intimate material, stalking, hacking, and identity misuse may involve offenses separate from defamation. Immediate danger should be reported to the police or appropriate emergency authorities.

Frequently asked questions

Can I file a case if the post did not use my name?

Yes, if people familiar with the circumstances could reasonably identify you from a photograph, nickname, position, location, prior posts, or other contextual clues. Identification must be proved, not assumed.

Is a private message libel?

A message sent only to the person criticized ordinarily lacks publication to a third person. If it is copied to someone else, placed in a group chat, or forwarded by its author to third persons, publication may exist. An online medium may make the applicable charge cyber libel.

Is a negative customer review defamatory?

Not automatically. A truthful account of personal experience or a clearly expressed opinion based on disclosed facts may be protected. Invented accusations of theft, fraud, professional misconduct, or other damaging facts present greater risk.

Can someone be charged merely for sharing a defamatory post?

Under Disini, a person who merely receives and reacts to a post through an ordinary Like, Comment, or Share function cannot be convicted as an aider or abettor of cyber libel. A person who writes a new defamatory assertion may be treated as the original author of that new content.

Does deleting the post prevent a case?

No. Deletion may reduce continuing harm but does not undo a publication already received by third persons. It can also make proof more difficult, which is why both sides should preserve an accurate copy.

Does an apology or affidavit of desistance dismiss the case?

Not automatically. It may support settlement, mitigation, or an evaluation of the evidence, but a criminal prosecution is brought in the name of the People of the Philippines. The prosecutor or court is not invariably bound by the complainant’s later change of mind.

Must I prove financial loss?

Financial loss is not a separate element of criminal libel or slander. For civil damages, however, actual monetary loss must be supported by evidence. Other damages remain subject to their own legal requirements.
