Quick answer

To file an estafa or fraud complaint in the Philippines:

Stop further losses and immediately notify the bank, e-wallet, remittance company, marketplace, or other service involved.
Preserve the original messages, transaction records, account details, advertisements, contracts, receipts, demand letters, and proof of loss.
Report the incident to the police or the appropriate NBI unit, especially if identification, tracing, digital preservation, or other investigative work is needed.
Prepare a sworn complaint-affidavit explaining, in chronological order, who deceived you, exactly what was represented or entrusted, why it was false or misappropriated, how you relied on it, and what damage resulted.
File the complaint and supporting evidence with the prosecutor’s office that has territorial authority over the place where the offense—or an essential element of it—occurred.

A police or NBI report does not automatically start a criminal case in court. Ordinarily, the prosecutor first evaluates the complaint under the applicable DOJ-National Prosecution Service procedure. If the required evidentiary standard is met, the prosecutor files an information in court.

Not every unpaid loan, failed investment, broken promise, delayed delivery, or breached contract is estafa. There must be evidence of a form of fraud specifically punished by law, such as deceit existing before or at the time the victim parted with money, or misappropriation of property received under an obligation to return or deliver it.

What counts as estafa?

Article 315 of the Revised Penal Code, as amended by Republic Act No. 10951, recognizes several forms of estafa. The most common are:

Estafa by false pretenses or deceit

This may apply when a person, before or at the same time money or property is obtained:

Uses a fictitious name;
Falsely claims to have authority, qualifications, credit, property, an agency relationship, a business, or an existing transaction;
Makes a comparable fraudulent representation; and
Causes the victim to rely on that representation and suffer damage.

The sequence matters. For this form of estafa, the deceit ordinarily must precede or accompany the transfer of money or property. A false excuse made only after a legitimate debt arose does not automatically convert the debt into estafa.

Estafa through misappropriation or conversion

This may apply when a person:

Receives money, goods, or other personal property in trust, on commission, for administration, or under another arrangement requiring delivery or return;
Misappropriates or converts it, denies receiving it, or fails to account for it under circumstances showing conversion; and
Causes prejudice to another.

Ownership and the duty created by the parties’ agreement are critical. Money received as an ordinary loan generally becomes the borrower’s property, with an obligation to repay an equivalent amount. Nonpayment alone is therefore different from receiving money in trust or under a duty to return the same property or deliver it for a specified purpose.

Demand is especially important in misappropriation cases because it can help establish that the person was required to account for or return the property and failed to do so. Demand is evidence, however, not a substitute for proving every element of estafa.

Estafa involving a check

Issuing a postdated or unfunded check can fall under Article 315(2)(d) in the circumstances specified by that provision. The facts must still show the required deceit and causal connection. A check issued only for a debt that already existed is not automatically estafa merely because it later bounced.

A dishonored check may separately raise liability under Batas Pambansa Blg. 22. That offense has its own elements and written-notice requirements. Under BP 22, failure to pay or arrange full payment within five banking days after receiving notice of dishonor may create the statutory presumption of knowledge of insufficient funds. By contrast, Article 315(2)(d), as amended, refers to failure to cover the check within three days from receipt of notice as prima facie evidence of deceit. Have counsel assess the correct charge rather than treating the two laws as interchangeable.

The controlling text of Article 315 and its present monetary thresholds appears in Republic Act No. 10951.

When the dispute may be civil rather than criminal

Warning signs of a primarily civil dispute include:

The transaction was genuine when made, but one party later became unable to perform;
The complaint rests only on nonpayment, delay, poor workmanship, or breach of warranty;
There is no provably false representation that induced the payment;
The accused received money as a borrower or seller, not in trust or under a duty to return the same property;
The alleged promise concerns only a future act, with no reliable evidence that it was fraudulent when made; or
The loss resulted from business risk rather than a dishonest scheme.

Labels do not control. Calling an agreement a “trust,” “investment,” “partnership,” or “loan” does not settle the legal issue. Prosecutors and courts examine the actual terms, communications, handling of funds, and conduct of the parties.

Act immediately if money was transferred online

Contact the sending and receiving financial institutions as soon as possible. Ask them to:

Record the transaction as disputed or fraud-related;
Preserve transaction and account records;
Attempt a hold, recall, or other action legally available to them;
Give you a complaint or reference number; and
Explain what affidavit, police report, or supporting documents they require.

Do not assume that a transfer can be reversed. Whether funds can be held or returned depends on timing, the account’s status, applicable law, and the institutions’ investigation.

Republic Act No. 12010, the Anti-Financial Account Scamming Act, separately addresses money-mule activities and specified social-engineering schemes involving financial accounts. It also provides a framework for disputed transactions, temporary holding of funds, BSP investigation, and possible restitution where the legal requirements are satisfied. The official statutory text is available in Republic Act No. 12010.

If your complaint against a BSP-supervised financial institution remains unresolved after first raising it with that institution, you may use the BSP Consumer Assistance Mechanism. This regulatory complaint is not a substitute for a criminal complaint.

Preserve evidence properly

Keep complete, unedited copies of:

Contracts, order forms, invoices, receipts, acknowledgments, and promissory documents;
Bank statements, deposit slips, remittance receipts, e-wallet records, transaction IDs, QR codes, and account numbers;
The advertisement, listing, profile, website, or investment presentation that induced the transaction;
Full email threads and complete chat histories—not only selected screenshots;
Usernames, profile links, phone numbers, email addresses, and displayed account names;
Voice messages, call logs, recordings lawfully made, and meeting details;
Copies of identification or business documents supplied by the respondent;
Proof that a claimed license, property, authority, shipment, business, or transaction did not exist;
Written demands and reliable proof of delivery and receipt;
Dishonored checks, bank return slips, notices of dishonor, and proof that notice was actually received;
Names and contact details of witnesses; and
A computation of the exact amount lost and any amount later returned.

For electronic evidence, retain the original device and original files when possible. Export conversations using the platform’s available function, preserve metadata, and make read-only backups. Record the date and method of collection. Do not crop away timestamps or account identifiers, edit screenshots, impersonate another person, unlawfully access an account, or publish accusations online in an attempt to force repayment.

Where to report the fraud

You may seek investigative assistance from:

The local police station;
The PNP Anti-Cybercrime Group for an online or technology-enabled incident;
The NBI Fraud and Financial Crimes Division;
The NBI Cybercrime Division for computer-related fraud; or
An appropriate NBI regional or district office.

The NBI lists its fraud, cybercrime, and complaints-assessment services on its official divisions and services page. Its official site also provides an online complaint page, but confirm whether personal appearance and original documents are still required for the particular service.

Investigators may help identify account holders, collect statements, preserve digital evidence, coordinate with institutions, and build the case. Bring a government-issued ID, your written chronology, respondent information, and organized copies of the evidence. Obtain the report, docket, or reference number.

Where to file the formal complaint

The proper venue is generally the city or municipality where the offense was committed or where any essential ingredient occurred. That may be where the false representation was made or received, where money or property was delivered, or where entrusted property was converted. Online transactions, multiple transfers, corporate complainants, and acts spanning several places can create difficult venue questions.

Do not choose a prosecutor’s office merely because it is convenient. A complaint filed in the wrong place can be dismissed or delayed. Rule 110 states the general venue rule and the required contents of a criminal complaint in the Revised Rules of Criminal Procedure.

Depending on the circumstances, the complaint may be filed with the proper city or provincial prosecutor, a regional prosecution office, or another legally authorized office. Ask the receiving office to confirm territorial authority before filing.

How to prepare the complaint-affidavit

Write in numbered paragraphs and use facts rather than conclusions. Include:

Your full name, address, contact information, and capacity to complain.
The respondent’s full name and address, if known, plus any aliases and identifying account information.
When, where, and how the parties first communicated.
The respondent’s exact material representations or the terms under which property was entrusted.
Why those representations were false, or what duty to deliver, return, or account existed.
What you did because of the representation or arrangement.
Each payment or transfer, with its date, amount, method, recipient, and transaction reference.
What the respondent did with the money or property, insofar as supported by evidence.
The demands made, the response received, and proof of receipt.
The amount of damage, less any amount returned.
The participation of each respondent rather than treating everyone connected with a business or account as automatically liable.
A request that the appropriate criminal charge be filed.

Identify each attachment—for example, “Annex A”—and refer to it in the relevant paragraph. Attach sworn statements from witnesses with personal knowledge. If the complainant is a corporation or organization, include documents proving the affiant’s authority to act.

The affidavit must be sworn before a prosecutor or other official authorized to administer an oath, or, when permitted, a notary public. Never sign a statement containing facts you do not personally know without clearly identifying the source of the information.

The DOJ publishes an Investigation Data Form and other official forms. Its filing guide for preliminary-investigation complaints is available on the DOJ filing-requirements page. Confirm the current checklist, copy count, fees, office hours, and accepted electronic or physical filing channel with the particular prosecution office before submission.

What happens after filing?

The prosecutor first checks the complaint and evidence. Current DOJ-NPS rules use different tracks depending on the penalty prescribed:

Regular preliminary investigation generally applies to offenses punishable by at least six years and one day, without regard to the fine, under DOJ Department Circular No. 015, series of 2024.
DOJ Department Circular No. 028, series of 2024, governs summary investigation and expedited preliminary investigation for specified offenses punishable from one day to six years, a fine, or both.

In a regular preliminary investigation, the prosecutor may dismiss an insufficient complaint at the initial evaluation or issue a subpoena. The respondent’s scheduled submission date must ordinarily allow at least ten days from receipt of the subpoena and complaint materials. The date stated in the actual subpoena controls and should never be ignored.

The prosecutor applies the current DOJ standard of prima facie evidence with reasonable certainty of conviction. This requires evidence that is admissible, credible, preservable, and capable of establishing all elements of the offense and the identity of the responsible person. The Supreme Court upheld the validity of this framework in Meking v. Remulla, G.R. No. 280455.

If the prosecutor finds the required basis, an information is filed in the proper court. The judge independently determines judicial probable cause for a warrant. Filing a complaint does not mean the respondent will automatically be arrested or convicted.

Barangay conciliation may occasionally be required

Most estafa complaints involving penalties above the Katarungang Pambarangay limits are excluded from mandatory barangay conciliation. A low-value form carrying a maximum imprisonment of no more than one year and no fine above ₱5,000, however, may require closer examination if the parties are natural persons actually residing in the same city or municipality.

Other exclusions include disputes involving juridical entities, parties residing in different cities or municipalities subject to the statutory adjoining-barangay exception, and situations requiring urgent legal action. The governing provisions are Sections 408 and 412 of Republic Act No. 7160 and Supreme Court Administrative Circular No. 14-93.

Because the result depends on the precise charge, penalty, parties, residences, and urgency, ask the prosecutor or a lawyer whether a Certificate to File Action is required before bypassing the barangay.

Penalties and monetary thresholds

For the ordinary forms listed in Article 315, the statutory bands under Republic Act No. 10951 are:

Amount of fraud	Statutory penalty
Not more than ₱40,000	Arresto mayor in its medium and maximum periods
Over ₱40,000 up to ₱1,200,000	Arresto mayor in its maximum period to prisión correccional in its minimum period
Over ₱1,200,000 up to ₱2,400,000	Prisión correccional in its minimum and medium periods
Over ₱2,400,000 up to ₱4,400,000	Prisión correccional in its maximum period to prisión mayor in its minimum period
Over ₱4,400,000	The law applies the maximum period and adds one year for each additional ₱2,000,000, subject to a 20-year ceiling

Article 315(2)(d), involving the check-based form specified by that provision, has a separate and substantially higher penalty schedule. Online commission may also trigger the Cybercrime Prevention Act, which can affect the charge and penalty. The final penalty depends on the precise offense, amount, date of commission, participation, modifying circumstances, and sentencing rules; it should not be calculated from the amount alone.

Can the complaint recover the money?

As a general rule, the civil action to recover civil liability arising from the offense is deemed instituted with the criminal action unless it is waived, reserved when the rules allow, or filed before the criminal case. State clearly in the complaint what amount remains unpaid and provide proof.

A criminal complaint is not a collection shortcut, and recovery is not guaranteed. Funds may already have been withdrawn or transferred, assets may be unavailable, and dismissal or acquittal can affect the civil aspect depending on the court’s findings. Ask counsel before filing a separate civil case, making a reservation, accepting a settlement, or signing an affidavit of desistance.

Common mistakes to avoid

Filing solely because someone failed to pay a debt;
Omitting the false statement that caused the payment;
Failing to explain when and where each essential act occurred;
Naming corporate officers, account holders, relatives, or employees without evidence of personal participation;
Submitting isolated screenshots without the complete conversation;
Losing the original check, device, document, or transaction record;
Sending notice of dishonor without preserving proof of actual receipt;
Inflating the loss or including amounts unsupported by records;
Waiting for a promised refund while evidence disappears or prescription runs;
Filing in the most convenient location instead of the legally proper venue;
Signing a prewritten affidavit without checking every statement;
Posting accusations, private data, or threats on social media; and
Paying a supposed “fixer” who promises an arrest, conviction, or guaranteed recovery.

When legal help is urgent

Consult a Philippine lawyer promptly if:

The amount is substantial or many victims are involved;
Funds may still be frozen or traced;
The respondent is using multiple identities, accounts, or jurisdictions;
The transaction involves cryptocurrency, securities, property titles, corporate funds, or overseas actors;
The accused is a business partner, trustee, employee, agent, or family member and ownership is disputed;
A bounced check or written notice of dishonor is involved;
You are uncertain whether barangay conciliation is required;
The proper venue is unclear;
The incident happened years ago;
You received a subpoena, counter-affidavit, dismissal resolution, or settlement proposal; or
There is intimidation, evidence destruction, continuing victimization, or a risk that funds will be dissipated.

Prescription periods vary with the applicable law and prescribed penalty. For Revised Penal Code offenses, Articles 90 and 91 govern; special-law charges may follow different rules. Do not assume that a police blotter, private demand, bank complaint, or informal mediation necessarily interrupts prescription.

Frequently asked questions

Do I need a lawyer to file?

A complainant may prepare and file an affidavit without private counsel, subject to the receiving office’s requirements. Legal assistance is advisable where the facts, venue, documents, amount, or possible charges are complicated. Qualified indigent complainants may ask the Public Attorney’s Office whether they meet its legal and merit requirements.

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

You may report the incident with the identifiers available, but prosecution requires reliable evidence identifying a responsible person. Preserve account numbers, profile URLs, transaction IDs, phone numbers, email addresses, device information, and communications so authorized investigators can seek records through lawful process.

Is a demand letter always required?

Not in every form of estafa. Demand can be highly important in misappropriation cases and written notice is critical in check cases, but it cannot create fraud where the other elements are absent. The content, service method, recipient, and proof of actual receipt matter.

Can several victims file together?

Victims may coordinate and disclose the larger pattern to investigators, but each should ordinarily provide a sworn account and individual proof of payment and reliance. Separate transactions may constitute separate offenses even when they follow one scheme. The prosecutor determines the proper charging arrangement.

Can I withdraw the case after receiving payment?

Payment, compromise, or an affidavit of desistance does not automatically extinguish criminal liability for a public offense. It may affect the civil claim or the evidence available, but the prosecutor or court controls the criminal proceeding. Obtain advice before signing a release, quitclaim, settlement, or desistance affidavit.

Can online estafa be charged under the Cybercrime Prevention Act?

Potentially. Section 6 of Republic Act No. 10175 covers crimes under the Revised Penal Code and special laws when committed by, through, and with the use of information and communications technologies, subject to controlling case law and the facts. Online financial-account scams may also implicate Republic Act No. 12010. The prosecutor determines the sustainable charge.

Does a police blotter already count as the complaint?

Usually not. A blotter records the report. The formal prosecutorial case generally requires a sworn complaint-affidavit and supporting evidence filed through the proper channel.

How long will the case take?

There is no reliable universal timetable. Duration depends on the applicable investigation track, service of subpoenas, number of respondents, volume of evidence, clarificatory proceedings, prosecutor workload, review proceedings, court docket, and motions or appeals. Keep your contact details current and retain stamped or electronically acknowledged copies of every filing.
