Quick answer

To start an estafa case, file a sworn complaint-affidavit with supporting evidence at the Office of the City or Provincial Prosecutor that has territorial jurisdiction over the offense. A police or NBI report can help investigate the respondent or obtain records, especially in online scams, but a blotter entry alone is generally not the formal prosecutor’s complaint.

Your evidence must show a legally recognized form of fraud under Article 315 of the Revised Penal Code—not merely an unpaid debt, failed investment, delayed delivery, or broken promise. For the common “false pretenses” form of estafa, show that:

The respondent made a material false representation or used another deceitful means;
The deceit existed before or at the time you parted with money or property;
You relied on it; and
You suffered measurable damage.

For estafa through misappropriation or conversion, show that the respondent received identifiable money or personal property under an obligation to deliver, return, or account for it, but instead misappropriated, converted, or denied receiving it. The precise mode matters because each has different elements.

Act quickly. Contact the bank, e-wallet, card issuer, or other financial institution immediately if funds may still be traced or an account remains compromised. Preserve complete records before accounts, messages, listings, or transaction histories disappear.

First determine whether the facts may amount to estafa

Article 315 covers several distinct forms of swindling. The most common are:

Estafa by false pretenses or deceit

This may apply when a person obtains money or property by falsely claiming, for example, to have authority, qualifications, credit, property, an agency relationship, a legitimate business, or a real transaction.

The central question is: What false statement or fraudulent act caused you to pay or surrender property?

The deceit must generally precede or accompany the transfer. A promise that was apparently genuine when made does not automatically become criminal merely because it was later broken. The Supreme Court has repeatedly required the false representation to be made before or at the time of the fraud, with the victim relying on it and suffering damage. See the Court’s statement of the elements in G.R. No. 255308, February 12, 2024.

Useful evidence may include:

The exact advertisement, offer, representation, or promise;
Proof that the representation was false when made;
Messages showing that the respondent knew it was false;
Proof that you relied on it in deciding to pay;
The payment or delivery record; and
Proof of the resulting loss.

Later excuses, blocking, disappearance, or refusal to refund can support the overall narrative, but they do not by themselves prove that the respondent intended to deceive you from the beginning.

Estafa through misappropriation or conversion

This may apply when money, goods, or other personal property were received in trust, on commission, for administration, or under another arrangement requiring the recipient to deliver or return the same property, and the recipient instead misappropriated or converted it.

The complaint should establish:

What money or property was received;
When, where, and under what agreement it was received;
The respondent’s specific obligation to return, deliver, or account for it;
The act showing misappropriation, conversion, or denial of receipt; and
The damage caused.

A loan ordinarily transfers ownership of the money to the borrower and creates an obligation to repay an equivalent amount. Mere failure to repay a loan therefore does not, without additional qualifying deceit, automatically constitute estafa through misappropriation. The Supreme Court explained this distinction in G.R. No. 161057, September 11, 2008.

A written demand and proof that it was received can be important evidence in a misappropriation case, but demand should not be treated as a substitute for proving the other elements.

Estafa involving a dishonored check

A bounced check does not automatically establish estafa. For Article 315(2)(d), the check and the surrounding transaction must satisfy the statutory requirements, including deceit connected with obtaining the money, goods, or credit. A check issued only to pay a pre-existing obligation ordinarily does not prove the required prior or simultaneous deceit.

A separate prosecution under Batas Pambansa Blg. 22 may be possible even when the facts do not establish estafa. BP 22 has its own requirements, including proof relating to the drawer’s knowledge of insufficient funds. Written notice of dishonor and proof of the drawer’s actual receipt are particularly important; the statute gives the drawer five banking days after notice to pay or make arrangements for payment. See Batas Pambansa Blg. 22.

For a check case, preserve:

The original check;
The bank’s return slip or dishonor notation;
The underlying agreement and delivery records;
The written notice of dishonor;
Courier receipts, acknowledgment, or other proof of actual receipt; and
Evidence showing when and why the check was issued.

Article 315(2)(d) contains a separate three-day statutory rule concerning prima facie evidence of deceit. Do not confuse it with BP 22’s five-banking-day rule.

Online fraud

An online transaction is not automatically “computer-related fraud” under the Cybercrime Prevention Act. That offense generally concerns unauthorized input, alteration, deletion, or interference involving computer data or systems.

However, estafa or another existing offense committed by, through, and with the use of information and communications technology may fall under Section 6 of Republic Act No. 10175, which can raise the prescribed penalty by one degree. The correct charge depends on how technology was used and what the evidence proves. See the Cybercrime Prevention Act of 2012.

Where to file

File with the Office of the City Prosecutor or Office of the Provincial Prosecutor covering the place where the offense, or an essential ingredient of it, occurred. Relevant places may include where:

The false representation was made or received;
Money or property was delivered;
Entrusted property was received or converted;
A check was delivered; or
Legally cognizable damage occurred.

Residence alone does not always establish venue. Venue in a criminal case affects the court’s territorial jurisdiction, so an incorrect choice can cause delay or dismissal. Rule 110 generally requires prosecution where the offense or one of its essential ingredients occurred. See the Rules of Criminal Procedure.

For an online transaction involving people, accounts, and transfers in different locations, bring the complete facts to the prosecutor’s office or a lawyer before selecting a venue.

When to approach law enforcement first

Go first—or simultaneously—to the PNP, the PNP Anti-Cybercrime Group, or the NBI when:

The offender’s real identity or address is unknown;
A social-media account appears fake or compromised;
Bank, subscriber, IP, device, or platform records must be traced;
Several victims or coordinated accounts are involved;
Evidence is disappearing;
There are threats, extortion, identity theft, or unauthorized account access; or
An immediate investigative or preservation request may be necessary.

The investigator’s report and evidence can later support the complaint-affidavit. Keep the report number, investigator’s name, and copies of everything submitted.

Check whether barangay conciliation is required

Prior barangay conciliation can be a condition before filing when the parties actually reside in the same city or municipality and the dispute falls within the lupon’s authority.

Important exceptions include offenses punishable by imprisonment exceeding one year or a fine exceeding ₱5,000, cases involving detained persons, urgent legal action, and other statutory exclusions. Because low-value estafa may carry a lower prescribed penalty, some cases can fall within barangay jurisdiction while more serious cases do not. The rules appear in Sections 408 and 412 of the Local Government Code.

Ask the prosecutor’s receiving section whether a Certificate to File Action is required for your particular facts. Do not assume that every estafa complaint is exempt.

What to prepare

The complaint-affidavit

Write a chronological, first-person account based on facts you personally know. Include:

Your full name, address, and contact details;
The respondent’s full name, known aliases, addresses, employer or business, and contact details;
The dates and places of the material events;
The exact representation, agreement, or entrustment;
Why the representation was false, or how the property was converted;
What caused you to part with the money or property;
The amount or property involved;
The payment method and recipient account;
Your efforts to verify, recover, or demand an accounting;
The loss or damage suffered; and
A numbered reference to every supporting annex.

Separate what you personally observed from what another person told you. If a witness has material firsthand knowledge, obtain that person’s own sworn affidavit.

For multiple respondents, state what each person did. Do not rely only on collective statements such as “they scammed me.” For several transactions, list each date, amount, representation, payment channel, and recipient.

The affidavit must be properly sworn before a prosecutor or another official authorized to administer oaths, or before a notary public when appropriate. Bring valid identification and do not sign the jurat in advance unless instructed.

Copies and the NPS form

Under the current DOJ-NPS rules, the filing set generally consists of:

The original complaint-affidavit;
Two duplicate copies for the official file;
One additional copy for every respondent;
The required NPS Investigation Data Form; and
Corresponding sets of witness affidavits and supporting evidence.

A receiving office may have local requirements concerning binding, labeling, electronic media, certified records, or payment of lawful filing fees. Confirm these directly with that office before filing, especially for voluminous or digital evidence.

Evidence to attach and preserve

Organize the evidence so that it proves the sequence from deception or entrustment to loss.

For payments and transfers:

Official receipts;
Deposit slips;
Bank or e-wallet statements;
Transaction reference numbers;
Card statements;
Recipient account names and numbers;
QR-code or payment-link details; and
Written confirmation from the financial institution, if available.

For communications:

The full conversation, not only selected screenshots;
Dates, times, usernames, account URLs, phone numbers, and email addresses;
Original email files and headers where available;
Voice messages, call logs, and lawful recordings;
The original device or an intact backup;
Exported platform data; and
Screen recordings showing the account, URL, and complete thread.

For a sale, investment, agency, or entrusted-property arrangement:

Contracts, proposals, invoices, delivery receipts, and acknowledgments;
Registration or licensing claims;
Ownership records;
Accountings and liquidation reports;
Demand letters and proof of receipt;
Advertisements and archived listings; and
Evidence contradicting the respondent’s representations.

Do not crop away usernames, dates, URLs, or transaction details. Keep untouched originals and make working copies. Record when and how digital files were obtained. Do not edit metadata, impersonate another person, access an account without authority, or hack a device to obtain evidence.

Filing procedure

Stop further loss. Contact the bank, e-wallet, card issuer, or platform immediately. Report disputed transactions, request that the account be secured, and ask what preservation or recall measures are available. BSP guidance advises consumers to report suspicious or unauthorized transactions to the financial institution immediately. See the BSP consumer-assistance channels.
Preserve and inventory the evidence. Create a timeline and an annex index. Keep originals separately.
Identify the proper offense and venue. The label “fraud” is not enough. Determine whether the evidence supports false pretenses, misappropriation, a check offense, a cybercrime-related charge, or primarily a civil claim.
Prepare the sworn filing set. Complete the complaint-affidavit, witness affidavits, NPS Investigation Data Form, annexes, and required copies.
File with the proper prosecution office. Obtain a stamped receiving copy and docket or reference number. Keep the official receipt for any lawful fee.
Comply promptly with orders. Attend scheduled hearings and answer requests for originals, clarification, or additional evidence. Notify the office in writing if your address or contact details change.
Track the resolution. Record the date you receive any resolution because reconsideration and review periods run from receipt.

Which investigation procedure applies?

The prosecution office—not the complainant—should classify the case based on the legally prescribed penalty and court jurisdiction.

Under DOJ Department Circular No. 15, regular preliminary investigation generally covers offenses whose prescribed penalty is at least six years and one day, regardless of fine. Under Department Circular No. 28:

Summary investigation generally covers offenses punishable by one day to one year, a fine regardless of amount, or both. It is ordinarily ex parte and is resolved from the complainant’s records.
Expedited preliminary investigation generally covers offenses punishable by one year and one day to six years that fall exclusively within first-level-court jurisdiction.
Cases cognizable by the Regional Trial Court may remain under regular preliminary investigation even when special jurisdictional rules are involved.

The current prosecutorial standard is prima facie evidence with reasonable certainty of conviction. This requires evidence that is admissible, credible, preservable, and sufficient—if uncontroverted—to establish every element and identify the responsible person. The Supreme Court upheld the DOJ’s authority to apply this standard in G.R. No. 280455, November 11, 2025.

The DOJ’s official circulars are available through its issuances page.

Current administrative periods

The DOJ rules set these general internal periods:

A regular preliminary-investigation complaint should ordinarily be resolved within 60 calendar days from assignment, with a maximum 30-day extension in specified circumstances such as complex issues, countercharges, consolidation, or reassignment.
An expedited preliminary investigation should generally be resolved within 20 calendar days from receipt of the entire case records after case build-up and docketing.
A summary investigation is to be resolved immediately upon receipt of the complete records.

These are administrative resolution periods, not promises that the entire criminal case will end within that time. Service problems, incomplete evidence, case build-up, review, court proceedings, or other lawful incidents can lengthen the process.

If a complaint is dismissed:

No motion for reconsideration is entertained under the summary-investigation track.
The period for reconsideration under expedited preliminary investigation is generally 10 calendar days from receipt.
Under regular preliminary investigation, the period is generally 15 days from receipt.

Further DOJ review may be available in qualifying cases, but separate and short deadlines apply. Consult counsel immediately upon receiving an adverse resolution.

The amount matters, but it is not the only issue

Republic Act No. 10951 adjusted Article 315’s monetary brackets. For the general Article 315 penalty schedule, the principal statutory markers are:

₱40,000;
₱1,200,000;
₱2,400,000; and
₱4,400,000, with an incremental rule above that amount.

Check-based estafa under Article 315(2)(d) has a separate, substantially harsher schedule, including an additional ₱8,800,000 marker. Cybercrime-related penalty enhancement may also change the applicable investigation and court.

Do not select a filing procedure solely from the amount lost. The mode of estafa, use of a check or ICT, applicable special law, and prescribed penalty must all be considered. The current statutory text is in Republic Act No. 10951.

What happens after filing?

The prosecution office first checks the form and completeness of the evidence. Depending on the applicable track, it may:

Require case build-up or missing evidence;
Dismiss the complaint from the records;
Issue a subpoena and require the respondent’s counter-affidavit;
Conduct a clarificatory hearing;
Resolve the complaint; or
Approve and file an Information in court.

A prosecutor’s decision to file an Information does not itself establish guilt. After court filing, the judge independently determines whether judicial probable cause exists and whether a warrant or other appropriate order should issue. Conviction ultimately requires proof beyond reasonable doubt.

The civil action to recover civil liability arising from the offense is generally deemed instituted with the criminal action unless it was waived, reserved, or previously filed, subject to Rule 111. State clearly and document the amount of restitution or damages claimed. Recovery is not automatic; it depends on the evidence, judgment, and available assets.

Common mistakes that weaken a complaint

Treating every unpaid debt or failed business deal as estafa;
Failing to identify the specific false statement or entrusted property;
Describing only the respondent’s later failure, without showing prior deceit;
Filing in a place with no legally sufficient connection to an element of the offense;
Submitting a police blotter but never filing a sworn prosecutor’s complaint;
Providing screenshots without full conversations, usernames, URLs, or timestamps;
Omitting bank records connecting the payment to the recipient;
Failing to provide a usable respondent address for service;
Using hearsay when a firsthand witness can execute an affidavit;
Sending a demand letter without preserving proof of receipt;
Discarding the original check, receipt, device, or digital file;
Altering or annotating the only copy of electronic evidence;
Combining unrelated transactions or respondents without explaining each act;
Exaggerating facts or attaching documents that contradict the affidavit;
Assuming an affidavit of desistance or repayment automatically ends the criminal case; or
Publicly naming and shaming the alleged offender instead of preserving evidence and using lawful channels.

When legal help is urgent

Obtain prompt assistance from a lawyer, the IBP legal-aid program, or another qualified legal-aid provider when:

The prescriptive period may be close;
The amount is substantial or many victims are involved;
The respondent is abroad, unidentified, or using multiple accounts;
Corporate, trust, investment, securities, recruitment, or cryptocurrency issues are involved;
You received a prosecutor’s resolution, subpoena, or court notice;
The case may involve both estafa and BP 22;
Venue is disputed;
Records must be preserved from a bank, telecommunications company, or platform;
The respondent threatens you or attempts to destroy evidence; or
You need provisional civil remedies to prevent assets from disappearing.

Under Articles 90 and 91 of the Revised Penal Code, prescription can vary according to the prescribed penalty—commonly five, ten, fifteen, or twenty years for the relevant penalty classes. The period ordinarily runs from discovery and is interrupted by filing the complaint or Information. In 2025, the Supreme Court clarified prospectively that filing a criminal complaint with the prosecution office tolls prescription even for offenses subject to summary procedure. See G.R. No. 258563, April 2, 2025.

Prescription is fact-sensitive. Do not delay filing merely because a long period appears to apply.

If the evidence shows only a civil claim

If the evidence establishes a valid debt, refund obligation, or breach of contract but not criminal deceit or misappropriation, the proper remedy may be collection, rescission, damages, or another civil action.

Qualifying money claims not exceeding ₱1,000,000, exclusive of interest and costs, may be brought under the Small Claims Rule in a first-level court. See the Supreme Court’s 2022 Rules on Expedited Procedures. Barangay conciliation may still be required when applicable.

A dismissed estafa complaint does not necessarily mean there is no enforceable civil obligation. It may mean only that the available evidence does not establish the elements or prosecutorial standard for a criminal charge.

Frequently asked questions

Do I need a lawyer to file?

No law generally requires a private complainant to have a lawyer merely to submit a complaint-affidavit. A lawyer is advisable when the amount is large, the correct charge or venue is uncertain, several respondents are involved, or prescription and asset recovery are concerns.

Is a demand letter always required?

No. Demand is not a universal element of every form of estafa. It can nevertheless be important evidence of misappropriation, conversion, non-accounting, or notice. Check cases have specific notice rules that must be followed carefully. A demand made after the transaction cannot create proof that deceit existed at the beginning.

Can I file if I know only the scammer’s username or account number?

Report first to a cybercrime-capable law-enforcement unit and the financial institution. Preserve every identifier and transaction record. Investigation may be needed to identify the person and obtain a service address before the prosecutor can proceed effectively.

Can the complaint be filed by email?

The DOJ rules allow electronic filing and virtual proceedings as alternatives when adopted and authorized by the particular prosecution office. There is no reason to assume that an ordinary email to any address constitutes valid filing. Confirm the office’s official channel, file format, copy requirements, and acknowledgment procedure, and retain proof of successful filing.

Will filing immediately freeze or return the money?

No. A criminal complaint does not automatically freeze an account or guarantee restitution. Immediate reporting to the financial institution and investigators may improve the chance of tracing or preserving funds, but any restriction, disclosure, or recovery must follow applicable law and procedure.

Can the complainant withdraw the case after payment?

The complainant may report payment, settlement, or desistance, but a criminal offense is prosecuted in the name of the People of the Philippines. A private agreement or affidavit of desistance does not automatically compel the prosecutor or court to dismiss the case.

How long will the whole case take?

The DOJ rules prescribe periods for prosecutorial investigation, but a case that reaches court has separate stages—including judicial probable-cause review, arraignment, pretrial, trial, and possible appeal. No responsible estimate can be made without knowing the evidence, service history, court, and defenses.
