Quick answer

To start an estafa case in the Philippines, file a sworn complaint-affidavit with supporting evidence in the Office of the City or Provincial Prosecutor that has territorial jurisdiction. You may first seek investigative assistance from the police or the National Bureau of Investigation, especially if the offender’s identity is unknown, the transaction occurred online, or records must be obtained from third parties.

A practical sequence is:

Immediately report the transaction to the bank, e-wallet, platform, or payment provider and request preservation of records.
Preserve the original messages, transaction records, documents, devices, checks, and proof identifying the offender.
Determine whether barangay conciliation is required.
Prepare a detailed, sworn complaint-affidavit and witness affidavits.
File the required copies and the NPS Investigation Data Form with the proper prosecution office.
Keep the receiving copy, docket number, official receipts, and every notice from the prosecutor.
Attend hearings and meet every deadline stated in a subpoena or order.

The prosecutor—not the complainant—determines the legally appropriate charge. A failed investment, unpaid loan, breached contract, or dishonored check is not automatically estafa. The evidence must establish the particular kind of fraud defined in Article 315 of the Revised Penal Code.

When a transaction may constitute estafa

Estafa generally requires fraud or abuse of confidence that causes measurable damage. Article 315 recognizes several different modes, each with its own elements. The two most common are the following.

Estafa through false pretenses or fraudulent representations

This may exist when:

The respondent made a false statement or fraudulent representation about an existing or past fact;
The respondent knew the representation was false;
The deception occurred before or at the same time the victim parted with money or property;
The victim relied on it; and
The victim suffered damage as a result.

Examples may include pretending to own property that the respondent does not own, claiming nonexistent authority or qualifications, impersonating another person, or offering an imaginary business, product, investment, job, or transaction.

The complaint must identify the particular representation—not merely describe the respondent as a “scammer.” State what was said or shown, when and where it happened, why it was false, how it induced payment, and what loss followed. The Supreme Court has consistently treated deceit and resulting damage as essential to this form of estafa. See Raña v. People.

Estafa through misappropriation or conversion

This may exist when:

Money, goods, or other personal property was received in trust, on commission, for administration, or under another obligation requiring delivery or return of the same property;
The recipient misappropriated or converted it, or denied receiving it;
The owner or another person was prejudiced; and
The transaction created the required fiduciary obligation rather than an ordinary debtor-creditor relationship.

For example, money delivered to an agent for a specified purpose may be different from money advanced under a simple loan. In a loan, ownership of the money generally passes to the borrower, whose obligation is to repay an equivalent amount. Failure to repay, without the required deceit or fiduciary conversion, ordinarily creates a civil claim rather than estafa. The Constitution expressly provides that no person may be imprisoned merely for debt. See Article III, Section 20 of the Constitution and Guingona, Jr. v. City Fiscal of Manila.

A demand is not always a legal element of estafa through misappropriation, but failure to account after a properly documented demand can be circumstantial evidence of conversion. See Lee v. People.

A dishonored check is not automatically estafa

For estafa under Article 315(2)(d), the check must generally have been issued to induce the victim to part with money, goods, or another valuable consideration at the time the obligation was incurred. A check later issued merely to pay a pre-existing debt ordinarily does not supply the prior or simultaneous deceit required for estafa.

Article 315 also provides a rebuttable inference of deceit when the drawer fails to deposit enough money to cover the check within three days after receiving notice of dishonor. Preserve:

The original check;
The bank’s return slip or written reason for dishonor;
A written notice of dishonor or demand;
Proof that the drawer actually received that notice; and
Evidence showing what the victim delivered in reliance on the check.

Issuing a bouncing check may separately violate Batas Pambansa Blg. 22, which has different elements, notice rules, defenses, and penalties. A prosecutor may assess both laws from the same facts, but liability under one does not automatically prove the other. See Batas Pambansa Blg. 22 and Nierras v. Dacuycuy.

Online fraud may involve additional laws

If estafa was committed through information and communications technology, Section 6 of the Cybercrime Prevention Act may apply and may raise the penalty by one degree. Depending on the facts, identity theft, computer-related fraud, illegal access, access-device offenses, securities violations, falsification, money-mule activity, or the Anti-Financial Account Scamming Act may also require investigation.

Do not select charges by copying labels from social media. Describe the complete facts and attach the electronic evidence so that the investigator and prosecutor can identify the applicable law. See Republic Act No. 10175.

Act immediately after discovering the fraud

Contact the financial institution

Report an unauthorized or fraud-induced transaction immediately to the bank, e-wallet issuer, remittance company, card issuer, or other financial institution. Ask for:

A complaint or reference number;
Written confirmation of the report;
Preservation of transaction and account-access records;
Available recall, hold, or recovery measures;
A certified or official transaction history; and
Instructions for securing the affected account.

Reporting does not guarantee reversal, particularly when funds have already been withdrawn or transferred. It can nevertheless protect the account and preserve evidence. The Bangko Sentral ng Pilipinas advises consumers to report unauthorized or suspicious transactions immediately. If the institution does not resolve a consumer complaint, BSP-supervised institutions may be escalated through the BSP Consumer Assistance Mechanism.

Change compromised passwords, enable multifactor authentication, sign out unknown devices, and secure the email address and mobile number linked to the account.

Preserve evidence before accounts or messages disappear

Keep original files whenever possible. Preserve:

Complete chat and email threads, including dates and account identifiers;
Exported conversations, not only cropped screenshots;
Profile names, usernames, account URLs, telephone numbers, email addresses, and user IDs;
Advertisements, listings, websites, livestreams, and representations made before payment;
Payment confirmations, deposit slips, bank statements, e-wallet records, QR codes, and reference numbers;
Contracts, invoices, receipts, delivery records, acknowledgment receipts, promissory notes, and checks;
Audio, video, photographs, and call logs lawfully obtained;
Proof of the respondent’s real identity, address, business affiliation, or control of the receiving account;
Demand letters and proof of delivery or receipt;
Communications after payment, including admissions, excuses, refund promises, blocking, or deletion;
Names and contact information of witnesses and other victims; and
A written chronology prepared while events are still fresh.

Do not edit original images, overwrite files, factory-reset a device, or delete the conversation after printing it. Keep backups and note who obtained each item and how. Electronic documents must still be authenticated and shown to be reliable under the Rules on Electronic Evidence.

Decide whether to approach investigators first

You may seek assistance from:

The local police station or appropriate PNP investigative unit;
The NBI Fraud and Financial Crimes Division;
The NBI Cybercrime Division for computer- or internet-related cases; or
Another agency responsible for the particular activity, such as the SEC for an unlawful investment solicitation.

Investigative assistance is especially useful when:

The respondent used a false or unknown identity;
Subscriber, platform, bank, CCTV, or device records must be lawfully obtained;
There are multiple victims or receiving accounts;
The scheme is continuing;
The respondent is threatening witnesses or destroying evidence; or
An entrapment or other law-enforcement operation may be appropriate.

The NBI’s official procedures contemplate an interview, sworn statements, submission of evidence, and device examination when relevant. See the NBI’s services for victims of fraud and victims of computer crimes.

Do not attempt an arrest, entrapment, account takeover, or unauthorized access yourself. Coordinate any operation with law enforcement.

Check whether barangay conciliation is required

Prior resort to the Katarungang Pambarangay may be a condition before filing when:

Both parties are natural persons who actually reside in the same city or municipality; and
The offense carries a maximum imprisonment not exceeding one year or a fine not exceeding ₱5,000.

This can affect lower-value ordinary estafa cases because ordinary estafa involving no more than ₱40,000—apart from the specially penalized check-based form under Article 315(2)(d)—carries a maximum imprisonment of six months.

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

The parties reside in different cities or municipalities, unless their barangays adjoin and they agree to conciliation;
A corporation, partnership, or other juridical entity is a party;
The offense’s maximum penalty exceeds one year or the fine exceeds ₱5,000;
One party is the government;
A public officer is involved in a dispute concerning official functions;
The accused is in custody;
Immediate legal action is needed; or
Delay may cause the case to prescribe.

When conciliation is required and no settlement is reached, obtain the proper certification to file action. Failure to satisfy this condition can make a complaint premature. See Sections 408–412 of the Local Government Code and the Supreme Court’s Circular No. 14-93.

Because coverage depends on residence, party status, penalty, and urgency, ask the prosecutor’s receiving office or a lawyer before assuming that a barangay certificate is unnecessary.

Choose the proper prosecution office

File with the Office of the City Prosecutor or Office of the Provincial Prosecutor whose territory includes the place where the offense—or an essential ingredient of it—occurred.

For estafa by deceit, relevant locations may include where the false representation was received, where the victim relied on it and parted with property, or where resulting damage occurred. For misappropriation, the place of receipt, required accounting, conversion, or delivery may matter. Online communications alone do not make every place where a message was viewed a proper venue.

State clearly in the affidavit what happened within the chosen city or province. Venue is a factual and jurisdictional issue, and a weak connection can cause delay or dismissal. Rule 110 provides that a criminal action should generally be instituted and tried where the offense was committed or where an essential ingredient occurred. See Rule 110, Section 15.

If the proper venue remains uncertain, bring the timeline and transaction records to the prosecution office or obtain legal advice before filing in multiple places. Do not conceal an earlier complaint or duplicate the same charge in different offices.

Prepare the complaint-affidavit

Write in numbered paragraphs and chronological order. Use specific facts rather than conclusions. The affidavit should contain:

The parties. State your complete name, address, contact details, and capacity to complain. Give the respondent’s full name and last known address. If a corporation is the complainant, attach proof that its representative is authorized.
Jurisdiction and venue. Identify the acts that occurred within the prosecution office’s territory.
The relationship and transaction. Explain how you met, what was offered or entrusted, and the agreed terms.
The exact deception or fiduciary obligation. Quote or accurately describe the representations, documents, promises concerning existing facts, or duty to deliver or return specific property.
Reliance and delivery. Explain why you relied on the representation and identify each payment or item delivered, including dates, amounts, recipients, account numbers, and reference numbers.
Why the representation was false or the property was converted. Connect this conclusion to documents, admissions, official records, witness knowledge, or later conduct.
Damage. Provide a clear computation of the actual loss and distinguish principal, recovered amounts, and consequential expenses.
Demand and response. If a demand was made, state when, how, and to whom it was sent, and attach proof of receipt and any response.
Witnesses and exhibits. Identify each witness and document and explain what it proves.
Requested action. Ask that the appropriate charge be filed based on the evidence; do not demand a guaranteed arrest or conviction.

The affidavit must be based on personal knowledge, identify the source of information, and be sworn before a prosecutor or another official authorized to administer oaths—or, when those officials are unavailable, a notary public. Bring a valid government-issued ID.

False statements in a sworn complaint can create criminal and other legal consequences. Do not exaggerate the amount, omit repayments, alter conversations, coach witnesses, or include accusations you cannot support.

Assemble the filing set

Under the 2024 DOJ-NPS rules, the standard filing set includes:

The original complaint-affidavit;
Two duplicate copies for the official file;
One additional set for each respondent;
A completed NPS Investigation Data Form;
Separate sworn affidavits from material witnesses;
Legible copies of supporting documents; and
Any barangay certification or corporate authorization that applies.

Label and index the attachments—for example, “Annex A,” “Annex B,” and so on—and refer to each annex in the affidavit. Bring the originals for comparison but submit an original instrument only when required and after obtaining a documented receipt. Ask whether the office requires bound sets, electronic copies, additional identification, or a particular format.

The prosecution rules permit electronic procedures in specified circumstances, but ordinary email should not be assumed to commence a case. Regular virtual proceedings ordinarily require an initial appearance, an order identifying official email addresses, and compliance with hard-copy requirements. Confirm any electronic filing channel directly with the prosecution office and retain proof of successful filing.

What happens after filing

The DOJ now uses different investigation tracks based primarily on the penalty prescribed for the offense:

Prescribed penalty and case type	DOJ procedure	General effect
One day to one year, a fine regardless of amount, or both	Summary investigation	Generally resolved ex parte from the complaint and evidence; the respondent may not first be subpoenaed
One year and one day to six years, within the stated first-level-court coverage	Expedited preliminary investigation	The prosecutor may resolve from the record or issue a subpoena for a shortened proceeding
At least six years and one day, or a case otherwise requiring the regular track	Regular preliminary investigation	The respondent receives the complaint and an opportunity to submit counter-evidence

For ordinary Article 315 modes, Republic Act No. 10951 uses loss brackets of ₱40,000, ₱1.2 million, ₱2.4 million, and ₱4.4 million, with additional increments above ₱4.4 million. Article 315(2)(d), involving postdated or insufficiently funded checks, has a separate and substantially higher penalty structure using thresholds that extend through ₱8.8 million. Cybercrime and other special laws may further change the penalty and investigation track. See Republic Act No. 10951.

The receiving office and prosecutor should classify the case from the precise offense, amount, related charges, and court jurisdiction. Do not rely only on the amount lost.

Summary investigation

A summary investigation is ex parte. After docketing, the prosecutor examines the complaint-affidavit and evidence and should immediately recommend dismissal or prepare an information. A motion for reconsideration is not allowed under the summary-investigation rule, although another remedy may depend on the resolution and governing DOJ appeal rules.

Expedited preliminary investigation

For expedited cases:

An assisting prosecutor generally evaluates form and completeness within three calendar days;
Necessary case build-up should be completed within 20 calendar days;
If a hearing is needed, the investigating prosecutor issues a subpoena within five calendar days of receiving the complete record;
The hearing date should be no later than 15 calendar days from receipt of that record;
No reply-affidavit or rejoinder-affidavit is ordinarily entertained;
The case should generally be resolved within 20 calendar days from receipt of the complete record after docketing and any case build-up; and
An aggrieved party may move for reconsideration within 10 calendar days after receiving the resolution.

Extensions to file pleadings are prohibited in this track. Follow the actual date stated in the subpoena.

Regular preliminary investigation

For regular preliminary investigation:

The office checks the complaint’s form and the completeness of evidence before docketing;
Within five calendar days after receiving the complete record, the investigating prosecutor should recommend dismissal or issue a subpoena;
The hearing should be set no later than 30 days from the prosecutor’s receipt of the complete record;
The respondent must ordinarily receive at least 10 days to submit a counter-affidavit;
A reply or rejoinder may be required only for material new issues and must be filed within 10 calendar days after receipt of the pleading answered;
The prosecutor generally has 60 calendar days from assignment to resolve the complaint, with a possible 30-day extension in specified complex cases; and
A motion for reconsideration must be filed within 15 days after receipt of the resolution.

The detailed rules are in DOJ Department Circular No. 015, series of 2024 and DOJ Department Circular No. 028, series of 2024. The Supreme Court has upheld the DOJ’s authority to apply these prosecutorial rules. See Meking v. Department of Justice.

These periods govern official action but do not guarantee that the entire prosecution or court case will finish within the same period.

The prosecutor’s evidence standard

The prosecutor files an information only when the evidence establishes a prima facie case with reasonable certainty of conviction. In practical terms, the available evidence must be admissible, credible, preservable, and capable—if left uncontroverted—of proving every element and identifying the responsible person.

This makes an evidence-complete filing important. A believable story unsupported by reliable documents or witnesses may not satisfy the standard. Conversely, voluminous screenshots without a clear explanation of the false representation, reliance, identity, and loss may also be insufficient.

A filed complaint does not mean immediate arrest

After investigation, the prosecutor may:

Dismiss the complaint;
Direct further case build-up where permitted; or
Approve an information for filing in court.

If an information is filed, the judge independently determines whether judicial probable cause exists and whether a warrant of arrest, summons, or another order is appropriate. A private complainant cannot lawfully promise or demand an automatic arrest merely because a complaint was filed.

If the complaint is dismissed, read the resolution immediately. The available remedy and deadline depend on whether the case underwent summary, expedited, or regular investigation and on the office that issued the resolution. Obtain legal advice promptly rather than relying on an informal request for reconsideration.

Recovery of the money or property

The civil action to recover liability arising from the alleged offense is generally deemed included with the criminal case unless the offended party waives it, reserves the right to file it separately, or previously filed a civil action. See Rule 111.

A criminal complaint does not guarantee repayment. Even after conviction, recovery depends on proof of the loss, the judgment, and the availability of assets. Keep certified transaction records, invoices, valuations, proof of ownership, and evidence of any partial refund.

Where the evidence shows only a debt or contractual breach, the proper remedy may be collection, rescission, damages, small claims, or another civil action. Before filing parallel cases, obtain advice about reservation of the civil action, potential duplication, prescription, and the effect of one proceeding on another.

Do not wait for the prescriptive period to expire

Article 90 of the Revised Penal Code assigns different prescriptive periods according to the penalty. Depending on the specific Article 315 mode, amount, and any special law, an estafa offense may fall within a five-, 10-, 15-, or even 20-year period. The period generally begins when the crime is discovered by the offended party or authorities, subject to the qualifications in Article 91.

The Supreme Court has clarified prospectively that filing a criminal complaint with the prosecution office interrupts prescription, including cases under summary procedure. See People v. Consebido.

Do not calculate prescription from the payment date alone or assume that a demand letter, police blotter, platform report, or private negotiation necessarily interrupts it. The correct date can depend on discovery, the completed offense, the exact charge, prior proceedings, and the offender’s absence from the Philippines. File promptly and seek urgent advice if several years have passed.

Common mistakes that weaken complaints

Treating every unpaid loan or failed investment as a crime;
Alleging a broken promise without proving that a relevant representation was already false when made;
Filing in a place with no established connection to an element of the offense;
Naming only a business or page without identifying the responsible natural person;
Omitting the respondent’s last known address, causing failed service;
Submitting cropped screenshots without the account identifier, date, context, or original file;
Failing to connect the receiving bank or e-wallet account to the respondent;
Giving inconsistent dates or loss amounts across the affidavit and attachments;
Combining several unrelated respondents or transactions without explaining each person’s participation;
Ignoring repayments or facts unfavorable to the complaint;
Relying on hearsay from unnamed victims instead of obtaining their affidavits;
Assuming a demand letter is always mandatory—or that it can replace proof of deceit or conversion;
Filing without required barangay conciliation;
Sending only an email to an unofficial address and assuming the case was docketed;
Missing a subpoena, hearing, reconsideration, or appeal deadline;
Publicly accusing the respondent in a way that creates separate legal risks; and
Paying a “recovery agent,” fixer, or supposed official who promises guaranteed arrest or fund recovery.

When legal or law-enforcement help is urgent

Seek immediate assistance when:

Funds were just transferred and may still be traceable;
The offender is continuing to solicit money;
A child, older person, migrant worker, or otherwise vulnerable victim is being targeted;
The scheme involves many victims, an investment pool, or five or more coordinated participants;
The respondent used threats, extortion, identity theft, or unauthorized account access;
Evidence, CCTV footage, platform data, or bank records may soon be deleted;
The respondent or assets may leave the Philippines;
A prescriptive deadline may be approaching;
The loss is substantial or business records are complex;
The prosecutor dismissed the complaint and a short review deadline is running; or
You are being pressured to sign a waiver, quitclaim, affidavit of desistance, or settlement you do not understand.

A settlement or repayment proposal should be documented and reviewed carefully. Accepting partial payment does not automatically erase a completed public offense, while an affidavit of desistance does not by itself compel the prosecutor or court to dismiss a case.

Frequently asked questions

Can I file directly with the prosecutor without a police report?

Generally, yes, if you can submit a complete complaint-affidavit and supporting evidence and any required barangay process has been completed. Police or NBI assistance is useful when investigation, identification, record preservation, or digital tracing is needed.

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

You may report the matter, but identifying and locating the responsible person is essential to prosecution and service of process. Seek NBI or police assistance and provide all account identifiers, links, telephone numbers, payment details, and device records. Do not guess a person’s identity in a sworn affidavit.

Is a demand letter required?

Not in every estafa case. It may nevertheless help establish conversion, refusal to account, notice of dishonor, or the amount claimed. Check-related cases have particular notice consequences. Use a method that produces reliable proof of actual receipt.

Can several victims file one complaint?

Possibly, when their transactions form part of the same scheme, but each victim should usually execute an affidavit and prove their own representations, payments, reliance, and loss. Whether complaints should be consolidated depends on the participants, acts, venue, and applicable procedural rules.

Does repayment end an estafa case?

Not automatically. Later payment may affect civil liability and may be relevant to intent or credibility, but it does not necessarily extinguish criminal liability for an offense already completed. The effect depends on the timing, terms, and evidence.

Do I need a lawyer?

A private lawyer is not invariably required to execute and file a complaint-affidavit. Legal assistance is strongly advisable when the amount is substantial, venue is disputed, the transaction is contractual or corporate, several laws may apply, electronic evidence is complex, prescription is close, or a prosecutor’s resolution must be challenged.
