Quick answer

To start an estafa case, file a sworn complaint-affidavit and supporting evidence with the proper City or Provincial Prosecutor’s Office—usually where the fraud occurred or where an essential part of it happened. The affidavit must show the particular form of fraud, not merely that someone failed to pay, return money, or keep a promise.

For an online scam or an offender whose true identity is unknown, promptly seek investigative assistance from the Philippine National Police Anti-Cybercrime Group or the National Bureau of Investigation. You may still need a formal filing with the prosecution office. Do not assume that a police blotter, bank dispute, platform report, or demand letter has already started the criminal case or stopped prescription.

Act immediately: report the transaction to the bank, e-wallet, or other financial institution; ask whether the recipient account or remaining funds can be held; change compromised credentials; and preserve complete records before accounts, messages, or listings disappear.

First determine whether the facts amount to estafa

Estafa is criminal fraud under Article 315 of the Revised Penal Code. The precise elements depend on how the fraud was committed.

Estafa through false pretenses or fraudulent representations

This commonly covers scams involving a fictitious identity, nonexistent business or transaction, false authority, fake qualifications, false ownership, or similar deceit. Ordinarily, the evidence must show that:

The respondent made a materially false representation or used a fraudulent act.
The deceit occurred before or at the same time the victim parted with money or property.
The victim relied on that deceit.
The reliance caused measurable loss or prejudice.

A lie made only after the money was delivered usually cannot supply the required prior or simultaneous deceit. The complaint should identify the exact representation, when and how it was made, why it was false, and how it induced the payment. These principles are illustrated in the Supreme Court’s decision in People v. Balasa.

Estafa through misappropriation or conversion

This form may apply when money, goods, or other personal property was received in trust, on commission, for administration, or under an obligation requiring its delivery or return, and the recipient later misappropriated, converted, or denied receiving it to another person’s prejudice.

The original arrangement matters. A loan normally transfers ownership of the borrowed money and creates an obligation to pay an equivalent amount; that is different from receiving specifically entrusted property for delivery, administration, or return. A written demand and proof of receipt are valuable because failure to account after demand can support an inference of misappropriation, although the Supreme Court has clarified that demand is circumstantial evidence rather than an invariable element in every abuse-of-confidence case. See G.R. No. 277067, May 7, 2025.

Fraud involving a dishonored check

A bounced check does not automatically establish estafa. For estafa under Article 315(2)(d), the check generally must have been used as the deceit that induced the victim to enter the transaction or part with property—not merely issued later to pay an existing debt. Lack of sufficient funds, damage, and deceit must be proved.

Written notice of dishonor and proof that the drawer actually received it are critical. Under Article 315, failure to fund the check within three days from receipt of notice may create prima facie evidence of deceit. A possible violation of Batas Pambansa Blg. 22 is distinct: its statutory period is five banking days after receipt of notice, and it may apply even when the check covered a pre-existing obligation. Preserve the original check, bank return slip, written notice, and reliable proof of delivery. Consult B.P. Blg. 22 and the Supreme Court’s discussion in Resterio v. People.

A broken promise or unpaid debt is not automatically criminal fraud

The Constitution prohibits imprisonment for debt. Criminal liability may nevertheless arise when independent evidence proves deceit or abuse of confidence as defined by law.

A delayed project, unpaid loan, failed investment, undelivered item, or breached contract does not by itself prove estafa. The Supreme Court distinguishes money parted with because of criminal deceit or abuse of confidence from an ordinary contractual obligation voluntarily assumed by the parties. See Benito v. People.

Identify all potentially applicable laws

Do not force every scam into a single Article 315 theory. Depending on the evidence, the prosecutor may consider:

The Cybercrime Prevention Act when estafa or another offense was committed through information and communications technology. Section 6 of Republic Act No. 10175 generally raises the applicable penalty by one degree.
The Anti-Financial Account Scamming Act for covered money-muling activities, social-engineering schemes, and related conduct.
B.P. Blg. 22 for dishonored checks.
Laws on illegal recruitment, securities, lending, access devices, falsification, identity misuse, or other special offenses when their separate elements are present.

State the facts completely and accurately. The prosecutor—not the complainant’s label—determines the legally supportable charge.

Where to file

The proper prosecution office

The usual filing point is the Office of the City Prosecutor or Provincial Prosecutor with territorial jurisdiction. Criminal actions generally belong where the offense was committed or where any essential ingredient occurred. In fraud cases, relevant places may include where the deceit was communicated, where the victim relied and parted with property, or where entrusted property was received or converted. Venue can be document- and fact-specific, especially for electronic transfers and parties in different locations.

Do not select an office solely because it is convenient or near your home. Bring the transaction records to the prospective prosecution office and confirm territorial jurisdiction before filing.

When law-enforcement assistance should come first

Approach the PNP Anti-Cybercrime Group, an NBI Cybercrime office, or the appropriate NBI fraud unit when:

The scammer’s real identity or location is unknown.
Subscriber, IP-address, device, platform, or financial-account records must be lawfully obtained.
Several accounts or accomplices were used.
The evidence may disappear quickly.
An entrapment, digital-forensic examination, or coordinated account tracing may be needed.

The NBI provides investigative assistance for victims of computer crimes and an online complaint page. A law-enforcement agency may investigate and refer the resulting complaint to the prosecutor.

Check whether barangay conciliation is required

Katarungang Pambarangay may be a precondition when the individual parties actually reside in the same city or municipality and the dispute is within the Lupon’s authority. Among the statutory exceptions are offenses punishable by imprisonment exceeding one year or a fine exceeding ₱5,000, disputes involving parties who do not meet the residence requirement, and situations requiring urgent legal action.

Because low-value ordinary estafa may carry a penalty not exceeding one year, some cases can require prior barangay proceedings and a Certificate to File Action. The rule depends on the parties, residence, offense, and prescribed penalty. Confirm this with the prosecutor or barangay before filing. See Sections 408 and 412 of the Local Government Code.

Complaints involving public officials, offenses connected with official duties, corporations, detained respondents, or special statutory forums may follow different routes.

Take these steps immediately after discovering the fraud

Contact the bank, e-wallet, card issuer, exchange, or remittance provider. Report the transaction as unauthorized or fraudulent, obtain a reference number, and ask about preservation, recall, or lawful holding procedures. Under the Anti-Financial Account Scamming Act and its rules, institutions have mechanisms for disputed transactions, but reporting does not guarantee recovery.
Secure compromised accounts. Change passwords from a trusted device, revoke active sessions, activate multi-factor authentication, and notify affected contacts.
Preserve the evidence before confronting the suspect. Export chats and emails, save transaction records, and capture public profiles or listings with URLs and timestamps. A premature confrontation may cause deletion of accounts or movement of funds.
Report impersonation or fraudulent content to the platform. Save the content and identifying information first. Record the report number and the platform’s response.
Do not send an additional “release,” “verification,” “tax,” or “recovery” fee. Recovery scams frequently target people who have already lost money.
Seek urgent assistance if the suspect is still communicating, funds remain traceable, other victims are being solicited, or threats and identity theft are continuing.

Evidence to preserve

Keep originals whenever possible and prepare readable copies. A strong file usually includes:

Contracts, order forms, invoices, acknowledgment receipts, delivery records, trust receipts, consignment documents, or investment papers.
Bank statements, deposit slips, remittance records, e-wallet receipts, transaction IDs, recipient account names and numbers, and written confirmations from the institution.
Complete chat or email threads—not only selected screenshots—showing dates, account identifiers, context, attachments, and the representations made before payment.
The advertisement, listing, website, social-media profile, username, profile URL, telephone number, email address, and any changes in account name.
Proof that a representation was false, such as verification from the real owner, employer, agency, licensing authority, company, or other reliable source.
Copies of identification documents supplied by the respondent, marked as unverified if authenticity is uncertain.
Written demands, notices of dishonor, courier receipts, registry returns, tracking records, acknowledgment messages, and other proof of actual receipt.
The original dishonored check and bank return slip, if applicable.
Names, addresses, and sworn statements of witnesses with personal knowledge.
A chronological loss schedule showing every payment, date, amount, channel, recipient, purpose, and supporting exhibit.
Police, NBI, bank, platform, or regulatory complaint reference numbers and responses.

Keep an untouched backup of digital files. Do not crop away timestamps or account identifiers, edit message text, recreate missing conversations, or submit a misleading compilation. Explain any missing record honestly.

How to prepare the complaint-affidavit

Write in chronological, first-person form. Use numbered paragraphs and identify each attachment as an annex. The affidavit should ordinarily state:

Your full name, address, contact details, and capacity to complain.
The respondent’s known name, address, contact information, account identifiers, aliases, and role.
When and where each material event occurred.
The exact statement, promise, document, identity, authority, or transaction represented to you.
Why that representation was false, and the evidence proving falsity.
That the deceit occurred before or simultaneously with your transfer of money or property.
How you relied on it and what you delivered because of that reliance.
The amount and nature of the resulting loss.
For entrusted property, the terms requiring delivery, accounting, or return and the acts showing conversion or misappropriation.
Any demand, notice of dishonor, response, admission, repayment, or refusal.
Facts establishing why the chosen prosecution office has territorial jurisdiction.
A request that the respondent be investigated and charged with the offense or offenses supported by the evidence.

Separate what you personally witnessed from information obtained from another person. Each material witness should execute a separate affidavit. Do not exaggerate, conceal repayments, or describe an inference as an established fact.

A corporate complainant should also prepare proof that its representative is authorized to execute and pursue the complaint.

Filing requirements and procedure

1. Confirm the office’s current checklist

The DOJ’s published checklist for complaints directly filed by private persons calls for:

Two copies of the accomplished, sworn NPS Investigation Data Form No. 1.
A complaint-affidavit or sworn statement.
Witness affidavits.
Supporting documents.
A Certificate to File Action when barangay conciliation applies.

The published checklist states five copies of the affidavits and supporting documents plus one for each respondent. Local requirements, electronic-filing availability, office hours, and document arrangement may change, so verify them before filing. See the DOJ’s Filing of Complaint for Preliminary Investigation page and official forms.

2. Have the affidavits properly sworn

The complaint and witness affidavits must be subscribed and sworn before a prosecutor or another government official authorized to administer oaths, or, when permitted, a notary public. Bring valid identification. Never sign a jurat falsely or claim personal knowledge of facts you learned only from someone else.

3. File a complete, indexed set

Arrange the papers consistently in every copy. Use an exhibit index and page numbers. For lengthy electronic records, include the portions establishing each element while preserving the complete source files for examination.

4. Obtain proof of filing

Keep a stamped receiving copy, NPS docket number, filing date, official receipt for any lawful fee, and the name of the office that accepted the complaint. Avoid fixers and unofficial payments.

5. Monitor notices and comply promptly

Use an address, email, and telephone number that you regularly check. Notify the office formally of any change. A missed hearing or unserved pleading can delay the case or leave important evidence unanswered.

Which investigation procedure applies

The applicable process is determined by the penalty prescribed for the offense, not simply by the amount lost.

For ordinary Article 315 forms using the general value-based penalty schedule under Republic Act No. 10951:

Amount of fraud	General statutory penalty	Usual NPS track
Not over ₱40,000	Arresto mayor in its medium and maximum periods	Summary investigation
Over ₱40,000 up to ₱1,200,000	Arresto mayor maximum to prisión correccional minimum	Expedited preliminary investigation
Over ₱1,200,000 up to ₱2,400,000	Prisión correccional minimum and medium	Expedited preliminary investigation
Over ₱2,400,000	A range whose maximum exceeds six years	Regular preliminary investigation

This table does not determine the process for every fraud case. Estafa by dishonored check has a separate, substantially higher penalty schedule. Cybercrime qualification, complex crimes, special laws, and offenses cognizable by the Regional Trial Court can also change the applicable track.

Under the current DOJ-NPS rules:

Summary investigation covers offenses generally punishable by one day to one year, a fine regardless of amount, or both. It is ordinarily resolved from the submitted records, and no motion for reconsideration is allowed.
Expedited preliminary investigation generally covers offenses punishable by one year and one day to six years that fall exclusively within first-level court jurisdiction. No reply-affidavit or rejoinder-affidavit is allowed. The investigating prosecutor’s resolution period is generally 20 calendar days from receipt of the complete records after case build-up and docketing. A motion for reconsideration may be filed within 10 calendar days from receipt of the resolution.
Regular preliminary investigation applies to offenses punishable by at least six years and one day. The prosecutor may dismiss an insufficient complaint or issue subpoenas, require a counter-affidavit, conduct clarificatory proceedings, and order additional evidence. The investigating prosecutor generally has 60 calendar days from assignment to resolve the complaint, with a maximum 30-day extension in specified cases. An aggrieved party generally has 15 calendar days from receipt of the resolution to move for reconsideration.

These are administrative periods, and approval, service, case build-up, consolidation, or lawful extensions can affect when the parties actually receive a final resolution. Follow the deadline written in the subpoena or order. The controlling issuances are DOJ Department Circular No. 15, series of 2024 and Department Circular No. 28, available through the DOJ’s issuances page. The Supreme Court upheld the validity of the heightened DOJ evidentiary standard in G.R. No. 280455.

What the prosecutor must find

The complaint is not decided under the trial standard of guilt beyond reasonable doubt. Under the current DOJ-NPS rules, however, the prosecutor will file an Information only when the available evidence establishes a prima facie case with reasonable certainty of conviction. In practical terms, the uncontroverted evidence should be capable of establishing every element of the proposed offense.

This is why a complaint consisting only of accusations, cropped screenshots, or proof of nonpayment may fail even when the complainant genuinely suffered a loss.

If the evidence is sufficient, the prosecutor prepares a resolution and Information for filing in court. Once the Information is filed, the judge independently determines whether judicial probable cause exists and whether a warrant of arrest should issue. Filing a complaint does not itself authorize the complainant, police, or prosecutor to arrest the respondent.

Prescription: do not wait

There is no single filing deadline for every estafa case. Under Articles 90 and 91 of the Revised Penal Code, prescription depends on the highest penalty prescribed by law:

Offenses punishable only by arresto mayor generally prescribe in five years.
Offenses punishable by another correctional penalty generally prescribe in 10 years.
Offenses punishable by other afflictive penalties generally prescribe in 15 years.
Offenses punishable by reclusion temporal generally prescribe in 20 years.

The period ordinarily runs from discovery of the crime by the offended party or authorities, not whenever the complainant later decides to make a demand. The Supreme Court has cautioned that a person cannot postpone prescription when circumstances already provided actual or constructive notice of the apparent misappropriation. Filing the complaint with the prosecution office interrupts the prescriptive period under the current rule.

The exact computation can change because of the Article 315 paragraph used, the amount, a cybercrime qualification, a special law, the date of discovery, earlier proceedings, dismissal, or the offender’s absence from the Philippines. Obtain legal advice immediately if substantial time has passed. Do not rely on repeated promises to pay or assume that a barangay, police, platform, or bank report necessarily preserved the deadline.

Recovery of the loss

When a criminal action is instituted, the civil action to recover civil liability arising from the offense is generally deemed included unless it was waived, reserved for separate filing, or filed earlier. Actual recovery still depends on proof, the court’s judgment, and the respondent’s available assets.

A separate collection, rescission, damages, regulatory, or consumer-remedy case may be appropriate even when the facts do not establish estafa. Coordination matters because filing, reservation, suspension, and double-recovery rules can affect parallel cases. B.P. Blg. 22 also has special rules concerning its accompanying civil action and filing fees. Obtain advice before electing or reserving civil remedies.

Common mistakes

Treating every unpaid loan or failed contract as estafa.
Failing to identify the specific deceit made before payment.
Submitting payment proof without showing who controlled the receiving account.
Naming a company officer solely because of position, without alleging that person’s own acts or participation.
Filing in a place with no legally relevant event.
Skipping required barangay conciliation.
Sending a bounced-check demand without reliable proof of actual receipt.
Using only cropped screenshots when complete conversations are available.
Altering digital evidence or overstating what a screenshot proves.
Concealing partial refunds, settlements, or inconsistent documents.
Filing several inconsistent complaints before different agencies.
Waiting for the scammer’s next promise while evidence disappears or prescription continues.
Assuming that filing automatically guarantees arrest, conviction, or repayment.

When legal help is urgent

Consult a Philippine lawyer promptly when:

Prescription may be near or the discovery date is disputed.
The amount is substantial or several victims are involved.
The fraud crossed cities, provinces, or national borders.
The respondent used multiple accounts, corporations, nominees, or possible money mules.
A check, investment, trust, corporate, securities, recruitment, or cybercrime issue is involved.
The respondent is a public official or employee.
You are being threatened, blackmailed, or pressured to sign a settlement or affidavit of desistance.
The prosecution office dismissed the complaint or issued an adverse resolution.
Funds or digital records may still be preserved through immediate lawful action.

Those who cannot afford private counsel may inquire with the Public Attorney’s Office, subject to its governing eligibility, merit, and conflict-of-interest rules.

FAQ

Can I file estafa directly with the police?

You may report the matter and request investigation, but a police blotter is not the same as a prosecution complaint. The police or NBI may gather evidence and refer the case, while the prosecutor determines whether an Information should be filed.

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

You can report the fraud immediately, but identifying the responsible person is important for prosecution and service of process. Seek cybercrime or fraud-investigation assistance so subscriber, platform, and financial records can be pursued through lawful channels.

Is a demand letter always required?

Not for every form of estafa. It is highly useful in entrusted-property cases and may be important evidence of conversion or failure to account. For dishonored-check cases, written notice and proof of receipt are especially significant because statutory cure periods run from receipt.

Must I hire a lawyer to file?

A private complainant may prepare and file a complaint-affidavit without private counsel. Legal assistance is advisable where the charge, venue, prescription, corporate authority, digital evidence, or parallel civil remedies are complicated.

Will the respondent be arrested as soon as I file?

No. The prosecutor first evaluates the complaint under the applicable investigation procedure. If an Information is later filed, the judge independently determines judicial probable cause and whether a warrant should issue.

What if the respondent offers repayment?

Document the offer and obtain advice before signing anything. Payment may affect damage, restitution, credibility, or settlement decisions, but it does not automatically erase a completed public offense. An affidavit of desistance does not compel the prosecutor or court to dismiss a case.

What should I do if the complaint is dismissed?

Read the resolution and record the exact date of receipt immediately. Depending on whether the case underwent summary, expedited, or regular preliminary investigation, a motion for reconsideration may be unavailable or due within 10 or 15 calendar days. Further review has separate procedural and jurisdictional rules. Do not wait until the final day to seek counsel.
