Quick answer
To file a criminal complaint in the Philippines, ordinarily submit a sworn complaint-affidavit, witness affidavits, and all supporting evidence to the Office of the City or Provincial Prosecutor that has territorial jurisdiction over the place where the crime—or an essential element of it—occurred. Complete the National Prosecution Service Investigation Data Form and bring the number of copies required by the receiving office.
For minor disputes covered by the Katarungang Pambarangay Law, barangay conciliation and a Certificate to File Action may be required first. Other cases—such as graft, election offenses, or certain tax and regulatory violations—may have to be filed with a specialized agency rather than the regular prosecutor’s office.
A police report or blotter entry helps document an incident but does not, by itself, necessarily commence the prosecutorial case. Conversely, a person may generally file with the proper prosecutor even without a prior police blotter, provided the complaint and evidence satisfy the applicable requirements.
Do not delay. Crimes have different prescriptive periods, and determining whether a prior report, barangay complaint, or prosecutorial filing interrupted prescription can involve difficult legal questions.
Where should the complaint be filed?
Regular criminal complaints
Most complaints for violations of the Revised Penal Code and general penal laws may be filed with the:
- Office of the City Prosecutor, if the crime occurred in a city; or
- Office of the Provincial Prosecutor, if the crime occurred within the province and the appropriate prosecution office is provincial.
Venue generally depends on where the offense was committed or where any essential ingredient of the offense occurred. The complainant’s residence is not automatically the proper venue.
Venue requires closer analysis when the transaction or conduct crossed several locations—for example, online fraud, cybercrime, offenses involving bank transfers, offenses committed aboard a vehicle, or a series of acts performed in different cities.
Complaints involving specialized jurisdiction
The appropriate receiving office may be different when the law gives investigative authority to a specialized body. Examples may include:
- The Office of the Ombudsman for offenses involving public officers that fall within its authority;
- The Commission on Elections for election offenses;
- The Bureau of Internal Revenue or Bureau of Customs for certain penal violations administered by those agencies;
- The Philippine Drug Enforcement Agency or other authorized law-enforcement agencies for matters governed by special procedures; and
- Military, administrative, or professional regulators when the same conduct may also create a separate disciplinary case.
A single incident can produce both a criminal case and an administrative, civil, labor, or regulatory case. Filing one does not necessarily substitute for the others.
Police report, barangay complaint, and prosecutor’s complaint are different
These steps serve different purposes:
| Document or proceeding |
Main purpose |
| Police blotter or incident report |
Records the reported incident and may begin police investigation |
| Barangay complaint |
Starts mediation or conciliation when the dispute falls within the lupon’s authority |
| Complaint-affidavit before the prosecutor |
Asks the prosecution office to investigate and, if warranted, file an information in court |
| Criminal complaint filed in court |
Commences a court proceeding in cases where direct filing is legally permitted |
| Information |
Formal accusation filed in court by the public prosecutor |
Reporting to the police is advisable when evidence must be secured, witnesses located, suspects identified, or immediate protection is needed. It is not invariably a legal prerequisite to filing a complaint-affidavit with the prosecutor.
Check first whether barangay conciliation is required
Sections 408 and 412 of the Local Government Code generally require prior barangay proceedings when:
- The dispute is within the lupon’s authority;
- The parties are individuals who actually reside in the same city or municipality; and
- No statutory exception applies.
If the parties reside in the same barangay, the dispute is ordinarily brought there. If they reside in different barangays within the same city or municipality, venue is generally the respondent’s barangay, subject to the specific rules for real-property, workplace, and school disputes.
Barangay conciliation does not cover, among others:
- A case in which the government is a party;
- A dispute against a public officer or employee relating to official functions;
- An offense punishable by imprisonment exceeding one year or a fine exceeding ₱5,000;
- An offense with no private offended party;
- Parties who reside in different cities or municipalities, unless the barangays adjoin each other and the parties agree to submit the dispute to the lupon; and
- Other matters excluded by law.
Direct resort is also allowed in circumstances identified in Section 412, including when the accused is detained, habeas corpus relief is needed, the action is coupled with specified provisional remedies, or delay may cause the claim to prescribe.
If conciliation fails, obtain the correctly issued Certificate to File Action and attach it to the prosecutor’s complaint. Do not assume that any barangay certificate will suffice.
Filing with the punong barangay interrupts the applicable prescriptive period only within the statutory limit: the period resumes upon receipt of the relevant certification, and the interruption cannot exceed 60 days. A complainant facing a possible prescription deadline should obtain immediate legal advice instead of relying on informal barangay assurances.
What documents should be prepared?
The usual filing package includes:
Complaint-affidavit. This is the complainant’s sworn narration of the material facts.
Affidavits of witnesses. Each witness should state facts personally known to that witness.
Supporting evidence. Depending on the case, this may include contracts, receipts, checks, demand letters, medical records, photographs, videos, messages, emails, bank records, titles, corporate records, forensic reports, or certified public documents.
National Prosecution Service Investigation Data Form. The applicable DOJ rules require an accomplished NPS Investigation Data Form. Depending on the type of investigation, it may need to be under oath.
Certificate to File Action. Attach this when prior barangay conciliation was legally required.
Proof of authority or representation. A corporation or other juridical entity should present documents showing that the person executing and filing the complaint is authorized to act for it.
Required copies. Under the current DOJ framework, the filing generally consists of the original, two duplicate copies for the official file, and one set for each respondent. Confirm the current intake requirements of the particular office before filing.
Bring valid identification for the administration of the oath and possible verification of identity. The prosecutor’s office may require additional documents based on the offense or local docketing procedure.
How to write the complaint-affidavit
A useful complaint-affidavit should identify:
- The complainant and current address;
- Each respondent and the most accurate address available;
- The date, time, and place of the incident;
- What each respondent personally did or failed to do;
- How the complainant knows each material fact;
- The injury, loss, or harm suffered;
- The witnesses and the facts each can prove;
- The supporting documents or objects attached; and
- The specific request that the respondent be investigated and prosecuted for the offense supported by the evidence.
Present events chronologically. Separate personal knowledge from information received from someone else. Identify every attachment clearly and explain its relevance.
The complainant need not force the facts into an incorrect legal label. Prosecutors determine the proper offense from the facts and evidence, although identifying the suspected violation may help organize the complaint. What matters is establishing every element of an actual crime and connecting the respondent to it through admissible, credible, and preservable evidence.
The affidavit must be sworn before a prosecutor or another officer legally authorized to administer oaths. Signing a false affidavit can create criminal liability.
Evidence should be admissible and capable of preservation
The current DOJ standard is not satisfied by suspicion alone. Under the 2024 DOJ-NPS rules, prosecutors determine whether there is prima facie evidence with reasonable certainty of conviction. The evidence should be admissible, credible, capable of preservation and presentation at trial, and sufficient—if left uncontradicted—to establish the elements of the offense and the identity of the responsible person.
Practical evidence-preservation measures include:
- Retain original documents and devices;
- Export complete conversations instead of submitting isolated screenshots;
- Preserve usernames, account links, email headers, transaction references, telephone numbers, dates, and timestamps;
- Keep original digital files with their metadata;
- Request CCTV preservation immediately because systems may overwrite recordings;
- Obtain medical examination and documentation promptly after physical or sexual violence;
- Keep receipts and records showing the source, destination, and purpose of payments;
- Record how and from whom each item of evidence was obtained;
- Do not alter, annotate, crop, enhance, or re-save the only original copy; and
- Maintain both secure backups and an organized evidence index.
A screenshot may be useful, but authenticity, completeness, identity of the account holder, and context may still have to be proved. Secret audio recording can raise issues under the Anti-Wiretapping Act; obtain advice before recording or submitting a private conversation.
Step-by-step filing process
1. Secure immediate safety and medical attention
For an ongoing threat, violence, abduction, sexual assault, or risk of evidence destruction, contact the police or appropriate emergency service immediately. Medical care and personal safety take priority over affidavit preparation.
Victims of violence against women and children may also approach the barangay, PNP Women and Children Protection Desk, prosecutor, social-welfare office, or court for the protection mechanisms appropriate to the facts.
2. Identify the proper offense, office, and venue
Review where every material act occurred, the penalty prescribed by law, whether barangay conciliation applies, and whether a specialized agency has authority.
3. Gather and preserve evidence
Prepare a chronology and an inventory of witnesses, documents, electronic evidence, physical objects, and official records. Secure time-sensitive evidence before it disappears.
4. Prepare the sworn affidavits
The complaint-affidavit and witness affidavits should contain facts based on personal knowledge. Attach readable, properly labeled copies of the evidence.
5. Complete the NPS data form and copies
Prepare the original and the required duplicate sets. A complaint may be delayed or refused for docketing if addresses, attachments, sworn statements, or copies are missing.
6. File and obtain proof of receipt
Submit the complete package to the proper docket or receiving section. Obtain a stamped receiving copy showing the date, time, office, docket number, and attachments received. Keep official receipts if fees are assessed under an applicable rule.
7. Monitor notices and comply promptly
Keep the office informed of changes in address, telephone number, or email address. Attend required hearings and answer lawful requests for clarification or additional evidence.
What happens after filing?
The applicable procedure depends largely on the prescribed penalty and the court that would hear the offense.
Summary investigation
Under DOJ Department Circular No. 028, summary investigation generally applies to offenses punishable by imprisonment from one day to one year, a fine regardless of amount, or both. It is an ex parte evaluation: the prosecutor may dismiss the complaint if the required evidentiary standard is absent or prepare an information if the standard is met.
Because the proceeding is ex parte, the respondent is not necessarily called to submit a counter-affidavit before the prosecutor acts.
Expedited preliminary investigation
Expedited preliminary investigation generally covers offenses punishable by imprisonment from one year and one day to six years that fall exclusively within the jurisdiction of first-level courts. The assisting prosecutor initially evaluates the complaint’s form and evidentiary completeness. Case build-up may be conducted when the affidavit or evidence is deficient.
If further proceedings are necessary, the investigating prosecutor issues a subpoena directing the respondent to appear and submit a counter-affidavit and supporting evidence. Reply-affidavits and rejoinders are not entertained under this expedited procedure, although the prosecutor may call a clarificatory hearing.
Regular preliminary investigation
Regular preliminary investigation applies to offenses within its coverage under the controlling rules, including cases cognizable by the Regional Trial Court. The respondent receives the complaint and evidence and is given an opportunity to file a counter-affidavit. The prosecutor may conduct case build-up or clarificatory proceedings when warranted.
The Supreme Court recognized the DOJ’s authority over prosecutorial preliminary investigations in A.M. No. 24-02-09-SC. The Court later upheld Department Circular No. 015 in Meking v. Remulla, G.R. No. 280455.
Resolution and court filing
The prosecutor may:
- Dismiss the complaint;
- Direct or facilitate further case build-up when authorized;
- Find sufficient evidence and prepare an information; or
- Take another action permitted by the governing rules.
A prosecutor’s finding supporting prosecution does not itself establish guilt. If an information is filed, the court independently handles the criminal case, including judicial determination of probable cause for a warrant when applicable. Guilt must ultimately be proved beyond reasonable doubt.
If the complaint is dismissed
The available remedy depends on the procedure used.
Department Circular No. 028 provides that no motion for reconsideration is entertained in a summary-investigation case. In an expedited preliminary investigation, an aggrieved party may file a motion for reconsideration within 10 calendar days from receipt of the resolution.
Regular preliminary-investigation cases are governed by their own reconsideration and review provisions. The correct remedy, filing office, review authority, and period should be confirmed from the resolution and the governing DOJ issuance. Filing in the wrong office does not necessarily stop the deadline.
Judicial review is exceptional. Courts generally do not substitute their judgment for the prosecutor’s factual assessment unless legally recognized grounds—such as grave abuse of discretion—are established.
Special situations
The offender is unknown
A report may still be made to law enforcement. Provide every identifying detail available, including photographs, account information, vehicle details, device records, transaction trails, CCTV locations, and witness descriptions. Prosecutorial filing may require sufficient evidence identifying the person to be charged.
The respondent was lawfully arrested without a warrant
The case may proceed through inquest rather than ordinary preliminary investigation. The arrested person has constitutional and statutory rights, including the right to counsel and the right to question an unlawful arrest. Inquest deadlines are tied to the legally permitted period of detention, so both the complainant and respondent should act immediately.
The complainant is a minor or incapacitated person
A parent, guardian, authorized representative, social worker, or other person permitted by the applicable law may assist or initiate proceedings. Some offenses have special rules on who may file or consent to prosecution.
The complainant is a corporation
The affidavit should be executed by an officer or representative with personal knowledge or competent access to the corporate records. Attach a board resolution, secretary’s certificate, or other proof of authority when required. Employees who personally handled the transaction may need to execute separate affidavits.
Several persons participated
Describe the act of each person. Mere association, family relationship, employment, presence, or corporate position does not automatically establish criminal responsibility.
Civil liability is also involved
A criminal case may include civil liability arising from the offense, subject to the Rules of Court. Reservation, waiver, prior filing, independent civil actions, and settlement can affect the civil component. Obtain advice before signing a waiver, quitclaim, settlement, or affidavit of desistance.
An affidavit of desistance does not automatically require dismissal because prosecution of crimes is generally under State control. Its effect depends on the offense, evidence, circumstances, and procedural stage.
Common mistakes to avoid
- Treating a police blotter as the completed criminal complaint;
- Filing in the complainant’s city without checking where the offense occurred;
- Skipping mandatory barangay conciliation;
- Waiting for informal negotiations while prescription continues to run;
- Naming every employee, director, relative, or companion without evidence of personal participation;
- Submitting accusations based entirely on hearsay;
- Attaching screenshots without preserving the original device or complete conversation;
- Omitting the respondent’s usable address, causing failure of service;
- Signing an affidavit without reading or verifying it;
- Altering documents or coaching witnesses;
- Posting accusations publicly while the case is pending;
- Filing multiple inconsistent narratives with the police, barangay, prosecutor, employer, or regulator;
- Surrendering the only original evidence without keeping an inventory and receiving copy; and
- Assuming that repayment, compromise, or an affidavit of desistance automatically ends every criminal case.
When legal help is urgent
Consult a lawyer promptly when:
- The possible offense may prescribe soon;
- A victim remains in danger;
- A suspect has been arrested or detained;
- The case involves death, serious injury, sexual violence, trafficking, kidnapping, child abuse, domestic violence, firearms, or dangerous drugs;
- Digital records, CCTV footage, or financial data may soon be deleted;
- The incident occurred in several jurisdictions or online;
- The respondent is a public officer or the offense involves public funds;
- The complainant is a minor, elderly person, person with disability, or someone unable to protect personal interests;
- A settlement, waiver, or affidavit of desistance is being proposed;
- The prosecutor has dismissed the complaint and a reconsideration or review deadline is running; or
- The complainant may also face a countercharge.
Qualified indigent complainants may inquire with the Public Attorney’s Office, subject to its governing eligibility, merit, and conflict-of-interest rules. Victims may also seek assistance from the prosecutor’s office, police, NBI, social-welfare authorities, or specialized government units appropriate to the offense.
Frequently asked questions
Do I need a lawyer to file a criminal complaint?
Not in every case. A complainant may ordinarily execute and file a complaint-affidavit personally. Legal assistance is nevertheless valuable when venue, prescription, evidence, the elements of the offense, barangay conciliation, or specialized jurisdiction is uncertain.
Must I report to the police before going to the prosecutor?
Not always. A prior police report is generally not an absolute requirement for an ordinary prosecutorial complaint. Police assistance is important when investigation, identification, arrest, forensic examination, or immediate protection is needed.
Can I file directly in court?
The Rules of Criminal Procedure permit direct court filing in certain cases not requiring preliminary investigation, subject to rules on prosecutorial filing in Manila and other chartered cities and to later DOJ issuances governing investigation by prosecutors. Because the proper route depends on the penalty, court jurisdiction, location, and special law involved, filing with the proper prosecution office is ordinarily the safer course unless a specific rule authorizes or requires direct filing.
Is a demand letter always required?
No. A demand is required only when it is an element or legally material under the particular offense or factual theory. Even when not indispensable, a documented demand may help prove notice, refusal, misappropriation, or the parties’ positions. It cannot create criminal liability where the elements of a crime are otherwise absent.
How much evidence is needed?
The complainant should submit evidence establishing every element of the offense and the respondent’s identity and participation. Under the current DOJ-NPS framework, the standard is prima facie evidence with reasonable certainty of conviction—not bare suspicion or an unsupported accusation.
Can the complaint be filed online?
Current DOJ rules recognize electronic filing and virtual proceedings in specified circumstances, but implementation and accepted channels may vary among prosecution offices. Use only an address or portal officially confirmed by the receiving office. Do not assume that emailing an affidavit to an unofficial address validly filed the case.
Does filing
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 the required copies with the Office of the City or Provincial Prosecutor that has territorial jurisdiction over the place where the crime—or an essential element of it—occurred.
For offenses covered by the Katarungang Pambarangay system, the complainant must ordinarily complete barangay conciliation first and obtain the proper certification before going to the prosecutor or court. Other cases may require filing with a specialized agency, such as the Office of the Ombudsman, COMELEC, or a designated law-enforcement unit.
A police report or blotter entry helps document an incident, but it does not necessarily begin the formal prosecutorial case. Filing requirements, prescription periods, and the proper investigating office depend on the particular offense.
Where should the complaint be filed?
Office of the City or Provincial Prosecutor
Most complaints involving violations of the Revised Penal Code, special penal laws, or local ordinances may be initiated at the prosecution office covering the place where the offense was committed.
Territorial jurisdiction is important. The proper office is generally determined by where the crime or any essential ingredient of it occurred—not simply where the complainant or respondent lives. Online transactions, cybercrimes, continuing offenses, and crimes committed across several places require closer analysis.
The National Prosecution Service is responsible for investigating and prosecuting violations of penal laws under the Prosecution Service Act of 2010.
Police or another law-enforcement agency
A victim may first report the incident to the Philippine National Police, National Bureau of Investigation, or another competent agency. Investigators may:
- Record the report;
- Secure the scene and physical evidence;
- Interview witnesses;
- Obtain available video footage or electronic records;
- Arrange medical or forensic examination;
- Identify possible respondents; and
- Refer or endorse the completed records to the prosecutor.
A complainant may also file directly with the proper prosecutor when the law and the circumstances permit. However, police or NBI assistance is particularly useful when evidence must be preserved, suspects must be identified, records must be obtained through lawful process, or immediate protection is required.
Specialized investigating offices
The correct forum may be different when a law assigns jurisdiction to a particular body. Examples include:
- The Office of the Ombudsman for certain offenses involving public officers;
- COMELEC for election offenses;
- The Philippine Drug Enforcement Agency for matters within its statutory mandate;
- The PNP Anti-Cybercrime Group or NBI Cybercrime Division for cybercrime investigation; and
- Other administrative or regulatory agencies authorized by special law.
An agency report does not always replace the complaint that must eventually be filed with the prosecutor or appropriate investigating body.
Determine whether barangay conciliation is required
Barangay conciliation may be a mandatory precondition when the parties are individuals who actually reside in the same city or municipality and the dispute falls within the authority of the lupong tagapamayapa.
Under Sections 408 and 412 of the Local Government Code, barangay conciliation generally does not cover, among others:
- A dispute in which one party is the government or a government instrumentality;
- A dispute involving a public officer or employee concerning official functions;
- An offense punishable by imprisonment exceeding one year or a fine exceeding ₱5,000;
- An offense with no private offended party;
- Parties actually residing in different cities or municipalities, unless their barangays adjoin and the parties agree to submit the dispute;
- Certain disputes involving property in different cities or municipalities; and
- Other matters excluded by law.
The parties may also proceed directly in situations specified by law, including when the accused is detained, liberty has been unlawfully restrained, provisional remedies are sought, or delay may cause the action to prescribe.
If conciliation applies, bring the dispute to the proper barangay—usually the barangay where both parties reside or, when they reside in different barangays within the same city or municipality, the respondent’s barangay. Obtain the appropriate Certificate to File Action if no settlement is reached.
Do not assume that a barangay blotter is the same as barangay conciliation or a Certificate to File Action. They serve different purposes.
Filing with the punong barangay interrupts the applicable prescriptive period only within the limits stated in Section 410 of the Local Government Code. Because prescription can be lost through even a short delay, seek immediate legal advice if the deadline may be close.
What documents should be prepared?
Requirements may vary by prosecution office and type of offense, but a regular filing ordinarily includes:
Complaint-affidavit. This is the complainant’s sworn statement of the material facts.
Witness affidavits. Each witness should execute a separate sworn affidavit based on facts personally known to that witness.
Documentary and electronic evidence. These may include contracts, receipts, checks, demand letters, medical records, photographs, videos, messages, emails, account records, screenshots, transaction logs, and certified public documents.
Real or object evidence. Physical items should be identified, protected from alteration, and turned over only through a documented procedure.
NPS Investigation Data Form. Current DOJ-NPS procedures require the applicable investigation data form, completed as directed by the receiving prosecution office.
Barangay certification, when required. Attach the Certificate to File Action or the document showing why direct filing is permitted.
Copies for the official record and every respondent. Current DOJ-NPS rules generally require the original, two duplicate copies for the official file, and as many additional copies as there are respondents. Confirm the receiving office’s current checklist before filing.
Identification and authority documents. Bring valid identification. A corporate complainant or representative may need a board resolution, secretary’s certificate, special power of attorney, or other proof of authority.
Documents written in a language unfamiliar to the investigating prosecutor may require a reliable translation. Foreign public documents may require authentication or an apostille, depending on their nature and intended use.
How to write the complaint-affidavit
A complaint-affidavit should be factual, complete, and organized. It should ordinarily state:
- The complainant’s full name, address, and relevant personal circumstances;
- The respondent’s full name and address, if known;
- The date, time, and exact or approximate place of the incident;
- What the respondent personally did or failed to do;
- How the complainant learned each fact;
- The resulting injury, loss, or harm;
- The witnesses and evidence supporting the account;
- Facts showing why the chosen office has territorial jurisdiction;
- Prior demands, notices, or barangay proceedings, when legally relevant; and
- A request that the respondent be investigated and prosecuted for the proper offense.
Tell the story chronologically and identify each attachment by a consistent exhibit marking. If exact dates, amounts, or identities are genuinely unknown, say so rather than guessing.
A complaint must establish facts, not merely conclusions such as “the respondent committed estafa” or “the respondent defamed me.” The evidence should address the legal elements of the possible offense. A broken promise, unpaid debt, breach of contract, or failed investment does not automatically constitute a crime.
The affidavit must be signed and sworn before a person authorized to administer oaths. Never sign a false or materially misleading affidavit. Deliberate falsehoods may create criminal liability and damage the credibility of the entire case.
Filing procedure step by step
1. Protect safety and preserve evidence
If anyone is in immediate danger, contact emergency services or the police before preparing papers. Obtain medical treatment when necessary and ask that injuries, findings, and treatment be properly recorded.
Preserve the original evidence. Do not edit screenshots, crop away identifying details, reset devices, repair damaged objects, or delete embarrassing messages that form part of the conversation.
2. Identify the possible offense
Match the facts to the elements of the suspected crime. This determines:
- The proper respondent;
- The evidence required;
- Whether demand or notice is legally relevant;
- Whether barangay conciliation applies;
- The correct investigating office; and
- The applicable prescriptive period.
The prosecutor may apply the legally proper offense even if the complainant used a different label, but the complaint must contain the necessary facts and evidence.
3. Confirm jurisdiction and venue
Identify where the material acts occurred. For offenses involving several locations, determine where an essential element was completed. If uncertain, consult the receiving prosecutor or counsel before the prescriptive period expires.
4. Complete any mandatory preliminary step
This may include barangay conciliation, a statutory demand, referral through an investigating agency, or compliance with a procedure imposed by a special law. Do not manufacture a demand requirement where the offense does not require one.
5. Execute the affidavits and organize the attachments
Place the documents in chronological or logical order. Prepare an index for a large record. Retain the originals unless the receiving office lawfully requires their submission, and obtain a written acknowledgment for anything surrendered.
6. File with the proper office
Submit the complaint and all required copies to the docket or receiving section. Complete the NPS Investigation Data Form and pay only officially assessed fees, if any. Ask for a stamped receiving copy showing the date, time, docket number, and office that accepted the filing.
Current DOJ information on filing a complaint for preliminary investigation is available through the Department of Justice.
7. Monitor notices and attend when required
Keep contact information current and monitor the address and email stated in the complaint. Attend scheduled proceedings and comply with lawful orders. Failure to appear or submit requested evidence may delay the case or cause it to be resolved on an incomplete record.
What happens after filing?
The procedure depends partly on the penalty prescribed by law and the court that would have jurisdiction over the offense.
The DOJ’s present framework includes:
- Summary investigation for covered offenses punishable by one day to one year, a fine regardless of amount, or both;
- Expedited preliminary investigation for covered offenses punishable by one year and one day to six years that fall exclusively within the jurisdiction of first-level courts; and
- Regular preliminary investigation or inquest for cases covered by the 2024 DOJ-NPS Rules, including offenses cognizable by Regional Trial Courts.
These classifications come from DOJ Department Circular Nos. 015 and 028, whose implementation was recognized within the DOJ’s executive prosecutorial authority by the Supreme Court in A.M. No. 24-02-09-SC. In 2025, the Supreme Court also upheld Department Circular No. 015 as a valid exercise of that authority in Meking v. Remulla.
Evaluation and case build-up
The prosecutor may examine whether the complaint is sufficient in form and whether the evidence is complete. Depending on the applicable procedure, the prosecutor may dismiss an unsupported complaint, direct case build-up, issue a subpoena, require additional evidence, or proceed toward the preparation of an information.
Respondent’s opportunity to answer
When the applicable procedure requires or permits it, the prosecutor issues a subpoena furnishing the respondent with the complaint and supporting evidence and directing the submission of a counter-affidavit. The complainant must provide enough copies for service on every respondent.
Summary investigation under Department Circular No. 028 is ex parte. The precise procedure therefore cannot be assumed solely from the offense’s familiar name; it depends on its prescribed penalty and other jurisdictional rules.
Prosecutor’s determination
For DOJ-NPS investigations, the current prosecutorial standard is prima facie evidence with reasonable certainty of conviction. The prosecutor evaluates whether the available, admissible, credible, and preservable evidence can establish the elements of the offense and the identity of the responsible person.
Filing a complaint does not mean that the respondent is already guilty. The prosecutor may:
- Dismiss the complaint;
- Require lawful further proceedings or case build-up; or
- Find sufficient basis to file an information in court.
An information is the formal accusation filed by the prosecutor in court. After it is filed, the judge independently performs the judicial functions required by the Constitution and the Rules of Court, including determining whether a warrant of arrest should issue.
What if the suspect was lawfully arrested without a warrant?
When a person is lawfully arrested without a warrant, the case may proceed through an inquest instead of an ordinary preliminary investigation. An inquest is an expedited prosecutorial inquiry into the legality of the arrest and whether the evidence supports filing a case.
The arresting officers should promptly bring the arrested person and the records to the proper authorities. Statutory periods governing delivery to judicial authorities are strict and depend on the gravity of the offense.
The arrested person has constitutional rights, including the right to remain silent and to competent and independent counsel. A waiver of rights under Article 125 of the Revised Penal Code must comply with the requirements of Article 125 and Republic Act No. 7438.
A complainant should not attempt to arrange or provoke an unlawful arrest merely to accelerate a case.
Evidence worth preserving
Preserve evidence in its most original and complete form, including:
- Original documents, receipts, checks, and contracts;
- Complete message threads rather than isolated screenshots;
- Original photo, audio, and video files with available metadata;
- URLs, usernames, account identifiers, and dates of access;
- Device and platform information;
- Bank, e-wallet, courier, and transaction references;
- Medical certificates, clinical records, and photographs of injuries;
- CCTV footage before the system overwrites it;
- Demand letters and proof of delivery;
- Barangay and police records;
- Names and current contact details of witnesses; and
- A written chronology prepared while events are fresh.
For electronic evidence, preserve both the visible content and information connecting it to the relevant account, device, transaction, or person. Screenshots alone may be insufficient if authenticity or context is disputed.
Do not obtain evidence through hacking, unlawful interception, trespass, coercion, impersonation, or unauthorized access. Illegally obtained material can expose the complainant to separate liability.
Prescription: do not delay
Every criminal offense has a prescriptive period after which prosecution may be barred. The period depends on the law violated and the penalty prescribed. Different rules may govern offenses under the Revised Penal Code, special laws, and local ordinances.
The starting point and interruption of prescription can also depend on:
- When the offense was committed or discovered;
- Whether it is continuing or consists of several acts;
- Whether barangay conciliation was mandatory;
- Where and when the complaint was filed;
- The particular statute governing the offense; and
- Controlling Supreme Court decisions.
Do not rely on a police blotter, demand letter, private negotiation, or informal agency inquiry to interrupt prescription. Their legal effect is not interchangeable with filing the proper proceeding. Obtain case-specific advice immediately when the incident is old or the deadline is uncertain.
Common mistakes to avoid
Treating a police blotter as the formal complaint
A blotter records a reported incident. Unless the records are properly endorsed and docketed under the applicable procedure, it may not constitute the complaint that places the case
Quick answer
To file a criminal complaint in the Philippines, prepare a detailed complaint-affidavit under oath, attach the affidavits of your witnesses and all available supporting evidence, complete the National Prosecution Service Investigation Data Form, and file the required copies with the Office of the City or Provincial Prosecutor that has territorial jurisdiction over the place where the crime—or an essential element of it—occurred.
For some minor disputes, you must first undergo Katarungang Pambarangay proceedings and obtain a Certificate to File Action. Cases involving a person arrested without a warrant ordinarily proceed through inquest, while certain offenses must be brought before a specialized agency, such as the Office of the Ombudsman or COMELEC.
A police report or blotter entry is useful evidence, but it does not automatically constitute or replace the formal complaint required to begin prosecutorial proceedings.
Where should the complaint be filed?
The correct office depends on the alleged offense, its location, the identity of the respondent, and whether the respondent was lawfully arrested without a warrant.
Office of the City or Provincial Prosecutor
Most complaints for violations of the Revised Penal Code, special penal laws, and local ordinances may be filed with the appropriate city or provincial prosecution office.
As a rule, file where the crime was committed. If the offense consists of several essential acts committed in different places, jurisdiction may lie in any place where an essential ingredient occurred. Venue can be more complicated for online offenses, bounced checks, estafa, offenses committed aboard vehicles, and transactions spanning several cities or provinces.
Do not choose an office merely because it is convenient or because the complainant lives there. Filing in the wrong place can cause delay or dismissal without prejudice to refiling in the proper jurisdiction.
Police or another law-enforcement agency
You may first report the incident to the Philippine National Police, National Bureau of Investigation, or the law-enforcement agency responsible for the type of offense involved. Investigators can take statements, preserve a crime scene, obtain recordings, identify suspects, and prepare a referral to the prosecutor.
Reporting to law enforcement is particularly important when:
- immediate protection or arrest may be necessary;
- the offender’s identity is unknown;
- forensic examination or digital tracing is needed;
- physical evidence may disappear;
- several victims or suspects are involved; or
- the offense requires specialized investigation.
The investigating agency’s referral can support the case, but the complainant should still verify whether a formal complaint-affidavit and complete evidence package have actually been filed.
Inquest after a warrantless arrest
When a suspect has been lawfully arrested without a warrant, the case normally goes to an inquest prosecutor rather than through the ordinary complaint process. Inquest is a summary determination of whether the arrest was lawful and whether the available evidence warrants filing a case in court.
Immediately tell the police or prosecutor about witnesses, videos, medical findings, weapons, stolen property, or other evidence that must be included in the inquest record. Because detention and statutory time limits are involved, an inquest moves much faster than an ordinary investigation.
Specialized offices
Some matters follow special routes. Examples include:
- offenses involving public officers that fall within the jurisdiction of the Office of the Ombudsman;
- election offenses investigated by COMELEC;
- tax offenses handled under tax laws and agency procedures;
- violations requiring investigation by a specialized regulatory or law-enforcement body; and
- offenses for which a special law provides a different initiating procedure.
The proper forum cannot be determined solely from the name of the alleged offense. The respondent’s office, salary grade, participation, the penalty prescribed by law, and the factual allegations may matter.
Check whether barangay conciliation is required
Under Sections 408 to 412 of the Local Government Code, certain disputes between individuals who actually reside in the same city or municipality must first be brought before the proper barangay. If the dispute falls within the lupon’s authority, a complaint ordinarily cannot be filed directly with the prosecutor or court until the required confrontation has occurred and a Certificate to File Action has been issued.
Barangay conciliation generally does not apply when, among other statutory exceptions:
- one party is the government or a government instrumentality;
- a public officer or employee is involved and the dispute concerns 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 actually reside in different cities or municipalities, unless the barangays adjoin and the parties agree to submit the dispute;
- the accused is detained;
- immediate court action is needed to prevent the claim from prescribing; or
- another exception under the Local Government Code applies.
For disputes covered by the barangay system, venue ordinarily depends on the parties’ actual residences. Workplace, school, and real-property disputes have additional venue rules.
Filing with the punong barangay interrupts the applicable prescriptive period while the dispute is under mediation, conciliation, or arbitration, but the statutory interruption cannot exceed 60 days. After receiving the Certificate to File Action, do not assume that a fresh full limitation period begins. File promptly.
What the complaint-affidavit should contain
The complaint-affidavit is the complainant’s sworn factual account. It should identify the offense supported by the facts, but it is more important to allege and prove what actually happened than merely to recite a statutory label.
Include:
The complainant’s identity and address. State complete and current contact information.
The respondent’s identity and address. Provide the respondent’s full name and an address where a subpoena can realistically be served. If some details are unknown, say so and explain what efforts were made to identify or locate the respondent.
The date, time, and place. Identify when and where each material act occurred. If the exact time is unknown, give the most accurate period supported by the evidence.
A chronological account. Describe what the respondent personally did or said, how the complainant knows it, and what happened afterward.
The participation of each respondent. If several people are charged, do not treat them as a single group. State the specific act, instruction, agreement, assistance, or omission attributed to each one.
The resulting injury or loss. Explain any bodily injury, property damage, financial loss, threat, unauthorized transaction, or other harm.
The basis of personal knowledge. Separate facts personally witnessed from information learned from other people. The persons who directly witnessed material events should ordinarily execute their own affidavits.
The supporting exhibits. Identify every document, photograph, recording, message, medical record, receipt, or physical item attached.
A request for appropriate action. Ask that the respondent be investigated and, if the evidence meets the governing standard, charged with the appropriate offense.
The affidavit must be truthful and signed before an officer authorized to administer oaths. Knowingly making a material false statement under oath may expose the affiant to criminal liability.
Evidence to attach and preserve
The prosecution evaluates admissible, credible evidence that can be preserved and presented in court. Attach the best available proof rather than relying on conclusions or accusations.
Depending on the case, useful evidence may include:
- witness affidavits based on personal knowledge;
- police reports and blotter entries;
- medical certificates, medico-legal reports, photographs of injuries, and treatment records;
- contracts, acknowledgment receipts, invoices, checks, demand letters, and proof of delivery;
- bank statements and certified transaction records;
- original messages, emails, call logs, and social-media records;
- CCTV or dashcam footage;
- photographs with their original metadata;
- title records, deeds, inventories, or proof of ownership;
- forensic reports;
- records showing the identity or account used by the respondent; and
- the barangay Certificate to File Action, when required.
Preserve digital evidence properly
Do not rely only on cropped screenshots. Keep the original phone, storage device, email, account, message thread, URL, username, timestamps, and downloadable files. Export or back up the complete conversation where possible. Record how the evidence was obtained and who handled it.
Ask establishments to preserve CCTV footage immediately because systems may overwrite recordings automatically. A preservation request does not guarantee release; compulsory production may later require lawful process.
Do not edit recordings, impersonate another person, break into an account, or secretly obtain material through unlawful means. Evidence-gathering methods can create separate privacy, cybercrime, or admissibility problems.
Filing requirements and number of copies
Under the DOJ-NPS procedures, the initiating papers generally include:
- the original complaint-affidavit;
- two duplicate copies for the official file;
- an additional copy for each respondent;
- witness affidavits;
- supporting evidence;
- a duly accomplished NPS Investigation Data Form under oath, where required;
- the Certificate to File Action, if barangay conciliation was mandatory; and
- other documents required by the receiving prosecution office or the law governing the offense.
Large or unusual exhibits may require special handling. Before filing, confirm the current office-specific requirements, accepted storage media, filing hours, and payment assessment. The DOJ maintains an official page on the filing of complaints for preliminary investigation and provides downloadable materials on its forms page.
Bring valid identification and enough complete, clearly marked sets. Have the receiving copy stamped with the date, time, docket number, and list of documents received. Keep that copy permanently.
Step-by-step filing process
1. Address immediate safety and medical needs
Call emergency services or seek police assistance if anyone remains in danger. Obtain medical care first when there are injuries, poisoning, sexual violence, or psychological crisis. Tell the medical provider how the injury occurred and retain all records and receipts.
For violence against women or children, sexual offenses, child abuse, trafficking, and similar cases, approach the PNP Women and Children Protection Desk or the appropriate specialized agency. Protection-order remedies may be available separately from the criminal complaint.
2. Identify the possible offense and filing deadline
Determine the law potentially violated, its elements, where each element occurred, and the applicable prescriptive period. Prescription varies significantly: some offenses prescribe quickly, while others have much longer periods or special statutory rules.
A demand letter is required for some offenses or may be important evidence in others, but it is not universally required. Do not delay filing merely to send repeated demands if prescription or evidence loss is a concern.
3. Determine the correct venue and preliminary requirement
Confirm:
- the city or province where the offense or an essential element occurred;
- whether barangay conciliation is mandatory;
- whether the respondent has been arrested;
- whether a specialized agency has jurisdiction; and
- whether a special law requires a particular complainant, notice, certification, or procedure.
4. Organize the evidence
Create a timeline and exhibit index. Secure originals, make readable copies, identify witnesses, and note any missing evidence that law enforcement may need to obtain.
5. Prepare the affidavits
The complainant and each material witness should execute separate affidavits. Avoid copying identical statements if the witnesses saw different things. Each witness should state only what that witness personally knows.
6. File the complete sets
Submit the complaint package to the proper prosecution office or authorized receiving agency. Pay only officially assessed fees and obtain an official receipt where payment is required.
7. Record the case details
Keep the:
- docket or NPS number;
- receiving copy;
- date of filing;
- assigned prosecutor or division, if already available;
- official receipts;
- contact information provided by the office; and
- inventory of exhibits submitted.
8. Monitor notices and attend proceedings
Update the prosecutor in writing if your address, email, or contact number changes. Attend scheduled proceedings and bring originals when instructed. Do not contact, threaten, coach, or pressure the respondent or witnesses.
What happens after filing?
The precise procedure depends on the penalty prescribed by law, the court having jurisdiction, and whether the matter is governed by regular, expedited, summary, or special investigation rules.
Summary investigation
Under the DOJ’s 2024 rules on summary investigation, offenses punishable by one day to one year of imprisonment, a fine regardless of amount, or both may undergo an ex parte evaluation. The prosecutor examines the complaint-affidavit and supporting evidence and may recommend dismissal or prepare the corresponding information without requiring a counter-affidavit.
Expedited preliminary investigation
Offenses punishable by one year and one day to six years, when exclusively within the jurisdiction of a first-level court, generally fall under expedited preliminary investigation. The assisting prosecutor first checks the sufficiency of the complaint and completeness of the evidence. Case build-up may be undertaken when the papers or evidence are deficient.
If the case is docketed and the investigating prosecutor finds further proceedings necessary, the prosecutor may issue a subpoena requiring the respondent to appear and submit a counter-affidavit. Reply-affidavits and rejoinders are generally not entertained under this expedited procedure, although the prosecutor may conduct a clarificatory hearing.
Regular preliminary investigation
Cases outside the summary or expedited categories—including cases cognizable by the Regional Trial Court—may undergo regular preliminary investigation. The respondent is furnished the complaint and supporting evidence and is given an opportunity to submit counter-affidavits and controverting evidence.
The governing prosecutorial standard under the 2024 DOJ-NPS rules is prima facie evidence with reasonable certainty of conviction. The Supreme Court recognized the DOJ’s authority to adopt these rules in A.M. No. 24-02-09-SC, and later upheld Department Circular No. 015 in Meking v. Remulla.
Resolution and court filing
The prosecutor may:
- dismiss the complaint;
- require appropriate case build-up or clarification;
- recommend filing an information; or
- take another action permitted by the governing rules.
If an information is approved and filed, the criminal case formally proceeds in court. The judge independently determines whether judicial probable cause exists for issuing a warrant of arrest or taking other appropriate action. Filing a complaint with the prosecutor does not guarantee an arrest, conviction, or recovery of money.
Can the complainant seek reconsideration or review?
Available remedies depend on the type of investigation and the applicable DOJ or special-agency rules.
For expedited preliminary investigations, an aggrieved party may generally move for reconsideration within 10 calendar days from receipt of the resolution. A motion for reconsideration is not entertained in cases governed by summary investigation. Regular preliminary investigations and special agencies may have different review procedures and deadlines.
Read the resolution and notice of service immediately. Do not assume that all cases carry the same deadline, that an informal follow-up suspends it, or that a second motion is allowed. If the case is dismissed and prescription is near, obtain legal advice at once.
Criminal complaint versus civil recovery
A criminal proceeding is brought in the name of the People of the Philippines. The public prosecutor controls the prosecution once the case reaches court, subject to law and judicial supervision.
Civil liability arising from the offense is generally deemed instituted with the criminal action unless it is waived, reserved when reservation is legally permitted, or previously filed separately. Some offenses and special laws follow different rules.
If the main objective is repayment, return of property, damages, enforcement of a contract, or cancellation of a transaction, a civil action or administrative remedy may also be necessary. Nonpayment or breach of contract does not automatically become estafa. Criminal liability requires proof of every element of a specific offense.
Special restrictions on who may complain
Most public offenses may be reported by the offended party, a witness, or law enforcement, although direct evidence from the victim may remain essential. Certain offenses, however, cannot be prosecuted except upon a complaint filed by a person specifically authorized by law.
This issue can arise in offenses governed by Article 344 of the Revised Penal Code and in cases involving minors or persons who cannot act for themselves. The proper complainant may depend on the offense, the victim’s age and capacity, and amendments under special laws. Obtain advice before filing if the case involves marital offenses, sexual offenses, or a minor victim.
Common mistakes to avoid
Treating a blotter entry as the completed case
A blotter records a report. Confirm whether investigators obtained sworn affidavits and whether a formal complaint was transmitted to the prosecutor.
Filing in the wrong city or province
Residence alone does not establish criminal venue. Identify where the criminal acts and essential elements occurred.
Skipping required barangay proceedings
If Katarungang Pambarangay applies, filing without the required certification can result in premature dismissal or delay.
Naming everyone connected to the dispute
Relationship, employment, or corporate position alone does not establish criminal responsibility. State the individual participation of every respondent.
Submitting conclusions instead of facts
Statements such as “the respondent committed estafa” are not substitutes for facts proving deception, reliance, damage, and the other elements required by law.
Concealing unfavorable evidence
A prosecutor evaluates the entire record. Misrepresenting documents, omitting crucial context, or submitting altered evidence can destroy credibility and create additional liability.
Assuming every broken promise is criminal
A failed business transaction, unpaid debt, or contractual breach is not automatically a crime. The facts must satisfy all elements of the alleged penal offense.
Waiting for all possible evidence before filing
The complaint should be responsibly supported, but unnecessary delay can lead to prescription, lost CCTV, unavailable witnesses, or deleted records. Seek help early when evidence must be obtained through legal process.
Posting accusations online
Publicly naming or shaming the respondent may expose the complainant to defamation, privacy, contempt, or witness-related issues. Preserve evidence and use lawful reporting channels.
Accepting an unclear settlement
A barangay or private settlement can have binding consequences. Do not sign a quitclaim, affidavit of desistance, or settlement that you do not understand. Some crimes cannot simply be erased by private agreement, even if civil liability is settled.
When legal help is urgent
Consult a lawyer or seek immediate assistance when:
- the offense is close to prescribing;
- someone has been arrested or detained;
- there is continuing violence, stalking, coercion, or a credible threat;
- the victim is a child or vulnerable adult;
- sexual violence, trafficking, kidnapping, or serious physical injury is involved;
- the suspect may flee or destroy evidence;
- digital records or CCTV may soon be overwritten;
- several cities, provinces, or countries are involved;
- the respondent is a public officer;
- the complaint was dismissed and a review deadline is running;
- the case involves substantial funds, corporate records, or complex transactions; or
- the complainant may also face a countercharge.
Those who cannot afford private counsel may inquire with the Public Attorney’s Office about eligibility and available assistance. Victims may also ask the prosecution office, law-enforcement agency, or relevant social-welfare office about victim-assistance services.
Frequently asked questions
Do I need a lawyer to file?
A lawyer is not always legally required to submit a complaint-affidavit. However, legal assistance is strongly advisable when the offense, venue, evidence, prescription period, or possible countercharge is uncertain.
Can I file even if I do not know the suspect’s real name?
You may report the offense and provide every identifying detail available, such as photographs, account names, phone numbers, vehicle information, transaction records, or physical description. Law enforcement may need to investigate before the person can be properly named and served.
Is a demand letter always required?
No. A demand is legally required or evidentially important only in particular offenses and factual settings. It does not convert an ordinary debt or breach of contract into a crime.
Can I file the complaint directly in court?
The proper method depends on the offense, prescribed penalty, location, and applicable procedural rules. Current DOJ procedures cover summary, expedited, and regular prosecutorial investigations, while Rule 110 and special laws address how particular criminal actions are instituted. Filing through the proper prosecution office is generally the prudent course unless a specific rule authorizes or requires direct court filing.
Does filing guarantee that the respondent will be arrested?
No. The prosecutor determines whether an information should be filed. After court filing, the judge independently determines whether a warrant should issue. Some cases may proceed by summons or under other procedures.
Can the complaint be withdrawn?
A complainant may communicate a change of position, settlement, or affidavit of desistance, but that does not automatically end a public criminal case. The prosecutor or court determines the legal effect. Private settlement ordinarily cannot extinguish criminal liability unless the law provides otherwise.
How long does the process take?
There is no single dependable duration. The applicable investigation track, completeness of evidence, number of respondents, service of subpoenas, case build-up, complexity, review, and workload can all affect timing. The DOJ rules prescribe periods for particular procedural stages, but the actual course depends on the case record.
Does filing stop prescription?
Filing with the proper authority may interrupt prescription under the law applicable to the offense, while barangay filing has its own limited statutory effect. Different rules may govern offenses under the Revised Penal Code, special laws, and ordinances. Never rely on a general assumption; determine the specific prescriptive rule and file promptly.
