Quick answer

To file a criminal complaint in the Philippines, prepare a sworn complaint-affidavit describing the crime, identifying the respondent, and attaching the evidence and witness affidavits that support every element of the offense. File it with the prosecution office that has territorial jurisdiction—usually the Office of the City Prosecutor or Provincial Prosecutor where the crime occurred. Depending on the offense, you may first need barangay conciliation, a police or specialized-agency investigation, or a different filing route.

A police blotter is not, by itself, a criminal complaint in court. It records an incident and may begin a police investigation, but prosecution generally requires a proper complaint and supporting evidence. Filing also does not guarantee that charges will reach court: the prosecutor must determine that the evidence satisfies the applicable standard for filing an Information.

If anyone is in immediate danger, evidence may disappear, a suspect has just been lawfully arrested without a warrant, or the offense may soon prescribe, contact the police and the proper prosecution office immediately.

Where to file

The correct office depends on the offense, where it happened, the persons involved, and whether a special law assigns the case to another authority.

Office of the City or Provincial Prosecutor

For most offenses, file with the prosecutor covering the city or province where the crime was committed or where an essential part of it occurred. Under Rule 110 of the Revised Rules of Criminal Procedure, venue in a criminal case is generally tied to the place where the offense or any essential ingredient occurred.

The National Prosecution Service currently uses different investigation tracks according to the penalty prescribed by law:

Regular preliminary investigation generally covers offenses punishable by at least six years and one day, regardless of the fine, under DOJ Department Circular No. 15, series of 2024.
Offenses within the lower penalty ranges may undergo summary investigation or expedited preliminary investigation under DOJ Department Circular No. 28, series of 2024.
An offense falling within the Regional Trial Court’s jurisdiction may still require regular preliminary investigation even if another penalty-based category might appear relevant.

The prosecutor’s receiving staff should classify the case. A complainant should not guess the governing track solely from the ordinary name of the offense because qualifying circumstances, the amount involved, the victim’s age, relationship, use of a weapon, or another statutory fact may change the offense or penalty.

Police, NBI, or another investigative agency

You may first report the incident to the Philippine National Police, National Bureau of Investigation, or the agency responsible for the particular law. This is especially useful when investigators must:

secure a crime scene;
identify an unknown offender;
obtain CCTV footage or other time-sensitive evidence;
conduct forensic examination;
trace financial or electronic records;
recover property; or
prepare a referral for inquest after a lawful warrantless arrest.

The investigating agency may help prepare affidavits and refer the records to the prosecutor. Its investigation does not replace the prosecutor’s independent assessment.

First-level court

Rule 110 permits certain complaints for offenses not requiring preliminary investigation to be filed directly with a Metropolitan Trial Court, Municipal Trial Court in Cities, Municipal Trial Court, or Municipal Circuit Trial Court. In Manila and other chartered cities, however, complaints generally go through the prosecutor unless the city charter provides otherwise.

Because the DOJ’s current summary and expedited procedures affect how lower-penalty cases are processed, confirm the local filing route with the appropriate prosecution office before submitting directly to a court.

Offices with special jurisdiction

Some complaints belong elsewhere or require special handling, including matters involving:

public officers and offenses within the jurisdiction of the Office of the Ombudsman;
tax, customs, election, environmental, cybercrime, trafficking, or competition laws;
children in conflict with the law;
violence against women or children;
military personnel or offenses subject to a special statutory process; or
conduct that may be administrative, civil, or regulatory rather than criminal.

Filing with the wrong office can cause delay and may not protect you from prescription under every applicable law.

Check whether barangay conciliation is required

The Katarungang Pambarangay process may be a condition before filing when the dispute is within the lupon’s authority. Under Sections 408 and 412 of the Local Government Code, this generally concerns parties who actually reside in the same city or municipality and an offense punishable by no more than one year of imprisonment or a fine of no more than ₱5,000.

Barangay conciliation generally does not apply when, among other situations:

one party is the government or a government instrumentality;
the dispute concerns a public officer’s performance of official functions;
the offense is punishable by imprisonment exceeding one year or a fine exceeding ₱5,000;
there is no private offended party;
the parties reside in different cities or municipalities, unless their barangays adjoin and they agree to submit the dispute;
the accused is under police custody or detention;
urgent legal action is necessary;
the action is about to prescribe; or
another statutory exception applies.

When conciliation is mandatory, obtain the proper Certificate to File Action after the required proceedings fail. A certificate issued prematurely or by the wrong barangay officer may be challenged.

Filing with the lupon suspends prescription only for the period established by law—generally until the complainant receives the certification needed to file, but not for more than 60 days. Do not treat barangay proceedings as an unlimited extension.

Parties normally appear personally in barangay proceedings without counsel or representatives. Minors and persons legally unable to represent themselves may receive the assistance permitted by Section 415 of the Local Government Code.

Prepare the complaint-affidavit

A complaint is a sworn written statement charging a person with an offense. It may be subscribed by the offended party, a peace officer, or another public officer responsible for enforcing the law violated.

The complaint-affidavit should contain facts, not merely conclusions such as “the respondent committed estafa” or “the respondent threatened me.” State, in numbered paragraphs where practical:

Your full name, address, and relevant personal circumstances.
The respondent’s full name and known address. If some details are unknown, say so accurately and provide available identifying information.
The date, approximate time, and exact or best-known location of each material event.
What the respondent personally did or failed to do.
The words spoken, representations made, property taken, injuries caused, or transactions completed, as applicable.
How you know each fact—personal observation, a message you received, a document you signed, or another identified source.
The harm, loss, injury, or risk caused.
The evidence and witness affidavits attached.
A request that the respondent be investigated and prosecuted for the offense or offenses supported by the evidence.
A statement that the affidavit is true based on your personal knowledge and authentic records.

Do not exaggerate, conceal material facts, or copy statutory language without explaining what actually happened. A knowingly false sworn statement can create criminal and other legal consequences.

Have the affidavit properly sworn before a prosecutor or another officer authorized under the governing rules. Do not sign it in advance if the administering officer requires signing in that officer’s presence. Bring valid identification.

Build an evidence file

Current DOJ policy requires more than suspicion or an accusation unsupported by proof. For cases handled by the National Prosecution Service, the evidence must establish a prima facie case with reasonable certainty of conviction under the applicable DOJ rules. The prosecutor examines whether the available evidence is admissible, credible, capable of preservation and presentation at trial, and sufficient to establish the elements of the offense and the offender’s identity.

Depending on the case, preserve and attach:

sworn affidavits of eyewitnesses or persons with direct knowledge;
original contracts, receipts, checks, invoices, demand letters, and proof of delivery;
photographs, video, CCTV footage, and information identifying who recorded or obtained them;
complete message threads, emails, call records, usernames, account links, and timestamps;
bank, remittance, e-wallet, or payment records obtained lawfully;
medical certificates, medico-legal reports, laboratory results, and photographs of injuries;
police reports, blotter entries, incident reports, and inventory or recovery records;
birth, marriage, property, or business records when legally relevant;
proof of ownership, possession, value, or financial loss;
device information, file metadata, and unedited electronic files; and
the Certificate to File Action, when barangay conciliation was required.

Keep the originals safe unless an authorized officer formally receives them. Submit readable copies and retain an identical, indexed set. Ask for a written acknowledgment whenever original evidence or a device is surrendered.

For digital evidence, do not crop away identifying details, alter files, reset devices, delete accounts, or forward material repeatedly if doing so may change metadata. Make secure backups and record when, where, and how the evidence was obtained.

Confirm the prosecution office’s filing requirements

The DOJ’s published preliminary-investigation checklist identifies commonly required documents, including:

an Investigation Data Form;
the complainant’s complaint-affidavit or sworn statement;
witness affidavits;
supporting documents;
proof of prior barangay proceedings, when applicable; and
the required number of copies.

The online checklist refers to five copies plus a copy for every respondent for core submissions and supporting documents. Local intake procedures, updated circulars, electronic-filing arrangements, and the type of investigation may affect what must be submitted. Confirm the current checklist, accepted file format, office hours, and number of sets with the receiving prosecution office.

Arrange the documents in a consistent order. Use an index and label attachments—for example, “Annex A,” “Annex B,” and so on—matching the references in the affidavit.

File and secure proof of filing

At filing:

Present the complete complaint package to the proper receiving office.
Pay only an officially assessed fee, if one lawfully applies, and obtain an official receipt. The DOJ publishes a schedule of fees, but the office must determine which charge, if any, applies.
Obtain a stamped receiving copy showing the date, office, and docket or reference number.
Record the assigned prosecutor and hearing date when available.
Keep every subpoena, order, email, text notice, receipt, and proof of service.

If electronic filing is allowed, use only the address or platform officially designated by the prosecution office. Keep the sent email, attachments, delivery confirmation, and any acknowledgment. Sending documents to an unofficial or unconfirmed address may not constitute valid filing.

What happens after filing

Initial assessment and possible case build-up

The head of the prosecution office or designated prosecutor may examine whether the complaint is sufficient in form and whether the evidence is complete. The office may require missing evidence or case build-up before docketing or proceeding.

A complaint may be dismissed at an early stage if the evidence does not justify continuing the investigation. Submission does not give the complainant a right to have an Information filed.

Subpoena and respondent’s counter-affidavit

If the case proceeds, the prosecutor may issue a subpoena requiring the respondent to submit a counter-affidavit and supporting evidence. The complainant should monitor notices and attend any scheduled hearing.

The exact response period depends on the governing procedure. Regular preliminary investigations and expedited proceedings do not necessarily use the same deadline. Extensions may be unavailable or strictly limited. Follow the subpoena and current DOJ circular, not an informal verbal estimate.

Preliminary investigation is generally documentary and summary. A party ordinarily does not have a right to cross-examine the other side’s witnesses at this stage. The prosecutor may conduct a clarificatory hearing when necessary.

Resolution

The investigating prosecutor issues a resolution recommending dismissal or the filing of an Information, subject to the required approval within the prosecution service. If the evidence meets the governing standard, the prosecutor—not the private complainant—files the Information in the proper court in the name of the People of the Philippines.

Once an Information is filed, the court independently determines matters within its authority, including judicial probable cause for issuing a warrant of arrest. A prosecutor’s finding does not itself convict the accused. Guilt must still be proved in court beyond reasonable doubt.

Motion for reconsideration or review

A party receiving an adverse resolution may have a remedy under the applicable DOJ rules, but deadlines and permitted pleadings vary according to whether the proceeding was regular, expedited, or summary. Some summary proceedings do not allow a motion for reconsideration.

Read the resolution and proof-of-receipt date immediately. Do not assume that all prosecution cases use the older or more familiar 10-day or 15-day period. If review is contemplated, consult counsel promptly and verify the current remedy with the issuing office.

If the suspect was arrested without a warrant

An inquest is an informal, summary prosecutor’s investigation involving a person arrested and detained without a warrant. It examines the legality of the warrantless arrest and whether the person should remain in custody and be charged.

Police referral must be handled urgently because Article 125 of the Revised Penal Code limits how long an arresting officer may detain a person before delivery to the proper judicial authorities. The statutory periods are generally 12, 18, or 36 hours, depending on the gravity of the offense, subject to the law’s terms and valid waiver procedures.

A complainant or witness in an inquest should:

go immediately to the police or designated inquest prosecutor;
bring available evidence and identification;
give a truthful sworn statement;
identify evidence that still needs urgent preservation; and
remain reachable for clarification.

Do not attempt a citizen’s arrest unless its strict legal requirements are present. An unlawful arrest can expose the arresting person to liability and complicate the case.

Prescription: do not delay

Criminal offenses have different prescriptive periods. The period may come from the Revised Penal Code, Act No. 3326 for violations of special acts, or the special law defining the offense. The starting point, interruptions, exclusions, and effect of filing may differ.

Rule 110 generally states that institution of the criminal action interrupts prescription unless a special law provides otherwise. Supreme Court decisions recognize that the effect of filing must be determined from the particular law and procedural route involved. A blotter entry, demand letter, private negotiation, or incomplete submission should not be assumed to stop prescription.

Obtain legal advice immediately if substantial time has passed since the incident.

Special complaints requiring the offended person’s participation

Some offenses cannot be prosecuted in the usual manner without a complaint by a person specifically authorized by law. Article 344 of the Revised Penal Code, as amended, contains special rules for adultery, concubinage, and certain offenses against chastity. The proper complainant, inclusion of responsible parties, and effect of consent or pardon may be decisive.

Other special laws contain their own standing, certification, referral, or procedural requirements. When the offense involves a spouse, child, sexual conduct, family relationship, public officer, or specialized regulatory scheme, verify the current statute before filing.

Civil damages and recovery of property

A criminal complaint may include a claim for civil liability arising from the offense. Under Rule 111, that civil action is generally deemed instituted with the criminal case unless the offended party waives it, reserves the right to file separately, or has already filed it, subject to special rules and exceptions.

List and document the actual loss, medical costs, damaged or missing property, lost income, and other legally recoverable amounts. Keep receipts and valuation records. Do not assume that filing a criminal case automatically freezes assets, recovers property, or guarantees payment.

A separate civil, administrative, labor, family, or regulatory remedy may also exist. Whether it can proceed independently depends on the cause of action and applicable law.

Common mistakes to avoid

Treating a blotter entry as the completed criminal complaint.
Filing in the place where the complainant lives instead of the place connected to the offense.
Skipping mandatory barangay conciliation.
Naming an offense without alleging facts establishing each element.
Submitting screenshots without the complete conversation, account details, timestamps, or source files.
Relying entirely on hearsay when direct witnesses or records are available.
Altering, annotating, or surrendering the only copy of digital evidence.
Omitting inconvenient facts that the respondent can easily prove.
Using a generic affidavit copied from an unrelated case.
Signing an affidavit without understanding it or without proper oath administration.
Missing subpoenas, hearings, or submission deadlines.
Publicly posting accusations or evidence in a way that risks retaliation, defamation issues, witness contamination, or loss of privacy.
Assuming settlement automatically ends a public criminal prosecution.
Waiting for negotiations while the offense approaches prescription.

When legal help is urgent

Seek a lawyer or immediate government assistance when:

anyone faces continuing violence, threats, stalking, exploitation, or unlawful restraint;
the victim is a child or a person unable to protect their interests;
sexual violence, trafficking, domestic violence, or online sexual abuse is involved;
the suspect has just been arrested or remains detained;
a search, seizure, recovery operation, or forensic examination is needed;
evidence is controlled by a bank, platform, employer, telecommunications provider, or government agency;
the respondent is a public officer or law-enforcement employee;
the incident spans several cities, provinces, or countries;
you do not know the offender’s identity;
prescription may be close;
the prosecutor dismisses the complaint; or
the case involves large losses, multiple victims, complex transactions, or competing civil and criminal claims.

Persons who cannot afford private counsel may inquire with the Public Attorney’s Office, subject to its mandate, indigency requirements, conflict rules, and case evaluation. Victims may also seek assistance from the appropriate police women and children protection desk, social-welfare office, or specialized government agency.

Frequently asked questions

Can I file without a lawyer?

Yes. A lawyer is not universally required to submit a criminal complaint. Legal assistance is nevertheless valuable when identifying the correct offense, jurisdiction, evidence, and procedural track—particularly in complex or urgent cases.

Can someone else file for the victim?

A peace officer or authorized public officer may subscribe a complaint in circumstances allowed by Rule 110. Some offenses, however, require a complaint by the offended person or another person expressly named by law. An ordinary representative cannot automatically replace that person.

What if I do not know the suspect’s complete name?

Report all available identifying details and ask investigators for help. Do not knowingly name the wrong person. Whether a case can proceed against an incompletely identified respondent depends on the evidence and the ability to identify and notify the proper person.

Must I first send a demand letter?

Not for every offense. A demand may be relevant evidence for particular crimes or defenses, but it does not create criminal liability where the statutory elements are absent. It also should not be allowed to consume the prescriptive period.

Is there a filing fee?

Some prosecution-office services or motions carry official fees; others may not. Ask for an assessment and official receipt. Never pay an unofficial “facilitation” charge.

Will the respondent be arrested after I file?

Not automatically. The prosecutor first determines whether charges should be filed. If an Information reaches court, the judge independently evaluates whether a warrant should issue. Inquest cases following a lawful warrantless arrest follow a different sequence.

Can I withdraw the complaint after settlement?

You may inform the prosecutor or court of a settlement or execute an affidavit permitted by law, but private withdrawal does not necessarily terminate a criminal case. Crimes are prosecuted in the name of the People of the Philippines, and the effect of settlement depends on the offense, stage of proceedings, and applicable law.

How long will the process take?

There is no single reliable duration. The governing investigation track, completeness of evidence, service of subpoenas, number of respondents, case build-up, clarificatory proceedings, and office workload all matter. Preserve your receiving copy and make reasonable follow-ups using the docket number.

What if the prosecutor dismisses my complaint?

Obtain the complete resolution and record the date you received it. Determine immediately whether the applicable procedure allows reconsideration or review and what deadline applies. A lawyer should assess whether the missing issue is evidence, jurisdiction, an element of the offense, credibility, or a procedural defect.
