Quick answer

To start an estafa case, file a sworn complaint-affidavit, witness affidavits, supporting evidence, and a completed National Prosecution Service Investigation Data Form with the proper City or Provincial Prosecutor’s Office. File where the fraud—or at least one essential part of it—occurred. A police, NBI, platform, bank, or e-wallet report can support an investigation, but it is generally not a substitute for the criminal complaint filed with the prosecution office.

The complaint must prove more than unpaid money or a broken promise. It should show the particular deceit, abuse of confidence, misappropriation, fraudulent check, or other legally punishable act; how you relied on it or entrusted property; the resulting loss; and the respondent’s individual role.

For an online or financial-account scam, first notify the bank or e-wallet immediately, then report promptly to the NBI or PNP cybercrime unit so that funds and electronic evidence may still be traced or preserved.

First steps after discovering the fraud

Stop further losses. Do not send another “release fee,” “tax,” “verification payment,” or “recovery fee.”
Call the bank, e-wallet, card issuer, or payment provider immediately. Report the transaction as disputed or fraudulent, request a reference number, and ask whether a recall, account restriction, or temporary hold is possible. Under the Anti-Financial Account Scamming Act and BSP Circular No. 1215, covered financial institutions may temporarily hold disputed funds while conducting coordinated verification. A hold is not automatic and does not guarantee recovery.
Secure compromised accounts. Change passwords using a safe device, revoke unknown sessions, enable multifactor authentication, and notify the provider if an OTP, PIN, recovery code, ID image, or account credential was disclosed.
Preserve evidence before blocking the account. Export chats, download emails with their headers, copy profile and listing URLs, and save transaction records. Screenshots are useful, but original digital files and account exports are stronger.
Report online fraud promptly. The NBI accepts online complaints and provides investigative assistance through its Cybercrime Division and fraud investigators. A local police station or PNP cybercrime unit may also receive the report.

Do not arrange an entrapment, seize another person’s device, access an account without authority, or publicly accuse people whom the evidence does not identify. Coordinate any operation with law enforcement.

Is the case really estafa?

“Fraud” describes many schemes, but the criminal complaint must be based on facts that satisfy a particular law. The most common estafa theories under Article 315 of the Revised Penal Code are the following.

Estafa by false pretenses or deceit

The evidence should show that:

the respondent made a false pretense or fraudulent representation about such matters as identity, authority, qualifications, ownership, credit, agency, business, or an imaginary transaction;
the misrepresentation was made before or at the time you parted with money or property;
you relied on it; and
you suffered damage as a result.

The timing matters. A lie made only after a legitimate debt arose normally cannot be the deceit that induced the original transaction. The Supreme Court explains these elements in G.R. No. 239090.

Estafa by misappropriation or conversion

This commonly applies when money, goods, or other personal property were received in trust, on commission, for administration, or under an obligation to deliver or return the same property, and the recipient instead converted, misappropriated, or denied receiving it, causing prejudice.

Clearly identify:

what was entrusted;
the agreement or purpose for which it was delivered;
the respondent’s duty to deliver, account for, or return it;
the act showing conversion or misappropriation;
the loss; and
the demand for accounting or return and proof that it was received.

Mere failure to return funds does not automatically prove conversion. The prosecution still needs evidence of every element, as the Supreme Court stressed in G.R. No. 207373.

Estafa involving a dishonored check

A bouncing check can support estafa under Article 315(2)(d) when the check was what induced the complainant to part with money or property and the obligation was contracted when the check was issued. A check later given for a pre-existing debt ordinarily does not supply that required prior or simultaneous deceit.

Preserve:

the original check;
deposit slip;
the bank-returned check or official dishonor record;
the written notice of dishonor;
proof of the drawer’s actual receipt; and
proof that the amount remained unpaid.

Article 315 provides a three-day period after receipt of notice to deposit the amount needed to cover the check for purposes of its statutory presumption. A separate case may be possible under Batas Pambansa Blg. 22, which uses a five-banking-day period after receipt of written notice. The two offenses have different elements. A registry receipt showing that a letter was sent may not, by itself, prove actual receipt.

When nonpayment is only a civil dispute

Unpaid loans, delayed deliveries, failed businesses, breached contracts, poor-quality work, and unfulfilled promises are not automatically estafa. Criminal fraud generally requires deceit existing before or at the transaction, or a legally defined conversion or abuse of confidence afterward. A complaint that proves only a debt may be dismissed even if the creditor has a valid civil claim.

Conversely, calling an agreement a “loan,” “investment,” or “business transaction” does not prevent prosecution if the evidence establishes criminal deceit. The actual documents, communications, transfer of ownership, and conduct of the parties control.

Online scams and financial-account offenses

Estafa committed by, through, and with information and communications technology may be charged in relation to Section 6 of the Cybercrime Prevention Act, which provides a penalty one degree higher than the underlying offense.

Phishing, account takeovers, deceptive requests for sensitive account information, and the knowing use or rental of mule accounts may also fall under the Anti-Financial Account Scamming Act. Unauthorized manipulation of computer data may instead—or additionally—raise computer-related fraud, forgery, or identity-theft issues. Let the prosecutor assess the proper charges from the complete facts rather than forcing every online loss into one label.

Where to file

File with the City or Provincial Prosecutor’s Office that has territorial jurisdiction over the offense. The relevant place may be where:

the false representation was made or received;
the complainant relied and parted with money or property;
entrusted property was received or converted;
a check was issued, delivered, deposited, or dishonored, depending on the charge; or
another essential element occurred.

The respondent’s residence alone does not necessarily establish venue. Online transactions, transfers between different cities, and schemes involving foreign actors require a fact-specific venue analysis. State every relevant location in the complaint and obtain legal advice if more than one place is involved.

If the offender is unknown, report first to the NBI or PNP and provide the account number, e-wallet number, phone number, email address, username, URLs, device information, transaction references, and any known identity details. Do not assume that the named account owner is necessarily the person who designed the scam; the account may be stolen, fictitious, or used as a mule account.

Check whether barangay conciliation is required

Katarungang Pambarangay may be a condition before filing when the parties actually reside in the same city or municipality and the dispute is within the lupon’s authority. One statutory exception covers offenses punishable by imprisonment exceeding one year or a fine exceeding ₱5,000. Other exceptions include certain disputes involving the government, official acts of public officers, parties residing in different non-adjoining cities or municipalities, and situations requiring urgent legal action.

Because ordinary estafa involving not more than ₱40,000 carries a maximum imprisonment of six months, barangay conciliation may be required when the residence and other statutory conditions are met. A Certificate to File Action should then accompany the prosecutor filing.

Under Sections 408, 410, and 412 of the Local Government Code, filing with the punong barangay interrupts prescription during the proceedings, but that interruption cannot exceed 60 days. Do not assume barangay proceedings give an unlimited extension. Cybercrime charges or other special-law offenses may also change whether the barangay exception applies.

Evidence to preserve

Build a folder that another person can understand without relying on your memory.

Transaction and payment records

Keep:

bank or e-wallet statements;
transfer confirmations and reference numbers;
official receipts, invoices, and acknowledgment receipts;
deposit slips;
card records;
remittance documents;
checks and dishonor records;
delivery receipts and courier records; and
a calculation of the exact amount lost.

Ask the financial institution for authenticated or certified records when available. Do not submit altered screenshots or crop out information needed to identify the transaction.

Communications and electronic evidence

Preserve:

full chat exports, not only selected screenshots;
email messages with complete headers;
SMS messages and call logs;
usernames, profile IDs, page names, and profile URLs;
advertisements, listings, websites, domain names, and QR codes;
voice messages, photographs, videos, and original file metadata;
account-security notices and OTP messages; and
reports and reference numbers from platforms or service providers.

Keep an untouched master copy and work from duplicates. Record the date and method of collection. Electronic evidence may need authentication; being visible on a phone is not always enough to prove who created it or that it was unchanged.

Under Section 13 of the Cybercrime Prevention Act, service providers preserve specified computer data for limited statutory periods when properly ordered by law enforcement. Prompt reporting matters because a victim’s screenshot cannot replace subscriber, traffic, or provider records that have already been deleted.

Agreements, representations, and identity records

Include:

contracts, proposals, subscription forms, promissory notes, trust receipts, and investment documents;
permits, licenses, IDs, business registrations, or certificates presented by the respondent;
proof that a claimed property, authority, employment, business, or transaction was false;
written demands and proof of receipt;
witness affidavits; and
records showing each participant’s role.

Verify public records through the relevant government agency. A rumor, anonymous post, or unverified social-media accusation is not a substitute for admissible evidence.

How to prepare the complaint-affidavit

A complaint-affidavit is evidence, not merely a request that authorities “investigate everything.” It should be complete, chronological, and based on facts within the affiant’s personal knowledge.

Include:

The parties. Give the complainant’s and respondent’s complete names and addresses. If a name is unknown, provide the best available description and identifiers.
Jurisdiction and venue. State where each important act occurred and why the selected prosecution office has territorial jurisdiction.
A dated narrative. Use numbered paragraphs. Identify who said or did what, when, where, through which account or document, and in whose presence.
The precise deception or entrustment. Quote only the necessary words and attach the complete communication. Explain why the representation was false, or describe the duty to account for, deliver, or return the entrusted property.
Reliance and transfer. Explain why the representation caused you to transfer money or property. Identify the amount, date, recipient account, transaction reference, and supporting annex.
Damage. State the actual loss and how it was calculated. Separate the principal amount from expected profits, interest, or other claimed damages.
Demand or notice. Where relevant, describe the written demand or notice of dishonor, its manner of service, date of actual receipt, and the response.
Each respondent’s participation. Avoid treating every officer, employee, relative, or account holder as automatically criminally responsible. State the acts and evidence linking each person to the scheme.
Annex references. Mark and identify every document consistently—for example, “Annex A,” “Annex B,” and so on.
The request. Ask that the respondent be charged with the offense or offenses supported by the evidence and for other appropriate relief.

The affidavit must be sworn before a prosecutor or other government officer authorized to administer oaths, or, when they are absent or unavailable, before a notary public. Witnesses should execute their own affidavits instead of being summarized as unnamed sources.

Filing requirements

Under the 2024 DOJ-NPS rules, prepare:

the original complaint-affidavit;
two duplicate copies for the official file;
one additional complete copy for each respondent;
the same complete set of witness affidavits and annexes;
a duly accomplished and sworn NPS Investigation Data Form; and
a Certificate to File Action if barangay conciliation was required.

Bring valid identification and the original documents for comparison. Ask the receiving office about its current local checklist, authorized fees, payment method, and whether it requires additional physical or electronic copies. Obtain an official receipt and a stamped receiving copy showing the date, office, docket or investigation number, and annexes received.

The DOJ provides the Investigation Data Form and a public filing checklist. Electronic filing and virtual proceedings are alternatives under the 2024 rules, but do not assume that an ordinary email completes filing. Use only the prosecution office’s official address and instructions. When e-filing is authorized, hard-copy originals may still be required by a stated deadline.

What happens after filing

The prosecutor classifies the case according to the penalty prescribed by law and the court that would have jurisdiction.

Summary investigation

Under DOJ Department Circular No. 028, summary investigation generally covers offenses punishable by one day to one year, a fine regardless of amount, or both. It is an ex parte process: the prosecutor may resolve the case from the complainant’s submission without first obtaining a counter-affidavit.

Ordinary estafa involving not more than ₱40,000 generally falls within this category, unless another applicable law or circumstance changes the prescribed penalty. No motion for reconsideration is entertained in a summary-investigation case under Department Circular No. 028. If the complaint is dismissed, obtain advice immediately about any other remedy that may still be available.

Expedited preliminary investigation

This generally covers offenses punishable by one year and one day to six years that fall exclusively within first-level court jurisdiction. Ordinary estafa involving more than ₱40,000 but not more than ₱2,400,000 will ordinarily fall here, subject to the actual charge.

The prosecutor may resolve a complete case or issue a subpoena requiring the respondent’s counter-affidavit. No reply-affidavit or rejoinder-affidavit is ordinarily allowed, although a clarificatory hearing may be held. The investigating prosecutor’s target period for resolution is 20 calendar days after receipt of the complete records following case build-up and docketing.

An aggrieved party may file a motion for reconsideration no later than 10 calendar days from receipt of the resolution.

Regular preliminary investigation

The 2024 DOJ-NPS Rules on Preliminary Investigations and Inquest Proceedings generally apply when the prescribed penalty is at least six years and one day. The Supreme Court recognized the DOJ’s authority to issue these rules in A.M. No. 24-02-09-SC.

The respondent is ordinarily subpoenaed and given at least 10 days from receipt of the complaint and attachments before the scheduled submission of a counter-affidavit. The prosecutor may call a clarificatory hearing or require limited further affidavits when necessary. The target resolution period is generally 60 calendar days, with a possible 30-day extension for complex or capital cases.

A motion for reconsideration must be filed within 15 days from receipt of the resolution. A petition for review may also be available under applicable DOJ rules, but its formal requirements and deadlines are strict.

Filing in court

If the prosecutor finds prima facie evidence with reasonable certainty of conviction, the prosecutor prepares an Information and files it in the proper court after the required approval. The court then makes its own determination of probable cause for purposes such as issuing a warrant of arrest.

Filing a complaint-affidavit does not itself mean that the respondent will be arrested immediately, and a prosecutor’s finding is not a conviction. Guilt must still be proved in court beyond reasonable doubt.

Current penalty brackets for ordinary estafa

Republic Act No. 10951 amended Article 315. These are statutory penalty ranges, not predictions of the sentence in a particular case.

Amount of fraud	Penalty prescribed by Article 315
Not more than ₱40,000	Arresto mayor in its medium and maximum periods: 2 months and 1 day to 6 months
More than ₱40,000 but not more than ₱1,200,000	Arresto mayor maximum to prisión correccional minimum: 4 months and 1 day to 2 years and 4 months
More than ₱1,200,000 but not more than ₱2,400,000	Prisión correccional minimum and medium: 6 months and 1 day to 4 years and 2 months
More than ₱2,400,000 but not more than ₱4,400,000	Prisión correccional maximum to prisión mayor minimum: 4 years, 2 months and 1 day to 8 years
More than ₱4,400,000	The statutory maximum-period formula applies, adding one year for each additional ₱2,000,000, subject to a 20-year ceiling

See Section 85 of Republic Act No. 10951. Cybercrime, syndicated estafa, complex crimes, attempted offenses, participation as an accomplice, and aggravating or mitigating circumstances may change the applicable penalty.

Do not wait for the deadline

Under Articles 90 and 91 of the Revised Penal Code, the prescriptive period for estafa can be 5, 10, 15, or—under some high-value penalty computations—20 years, depending on the amount and penalty legally applicable. The period generally runs from discovery of the crime by the offended party, authorities, or their agents, and is interrupted by the proper filing of the complaint or Information.

The computation can change because of:

the amount involved;
whether ICT or a special law applies;
when the fraud was legally discovered;
previous proceedings that ended or were stopped;
the offender’s absence from the Philippines;
barangay proceedings; and
whether an older filing rule applies to an older incident.

A police blotter, bank dispute, demand letter, or platform report should not be assumed to interrupt criminal prescription. Have a lawyer compute the period from the original records, especially if years have passed.

Recovering the money

A criminal case aims to prosecute an offense; it does not guarantee reimbursement. The civil action arising from the crime is generally deemed included with the criminal case unless it was waived, reserved, or previously filed separately. Civil liability may include restitution, reparation, and consequential damages, but the amount must be supported by evidence and actual collection depends on available assets and enforcement.

If the obligation is contractual rather than civil liability arising from a crime, a separate collection or rescission case may be necessary. Discuss before filing whether to:

pursue the civil claim with the criminal case;
reserve the right to file separately;
seek a civil provisional remedy when legally available;
use small claims for a qualifying money claim; or
pursue restitution or consumer redress through the financial institution.

A bank or e-wallet complaint is not a substitute for the criminal case, and the criminal case is not a substitute for a timely financial-consumer complaint. If the institution’s response remains unresolved, the matter may be escalated through the BSP Consumer Assistance Mechanism.

Common mistakes that weaken complaints

Filing because money remains unpaid without identifying deceit or conversion.
Omitting the exact false statement and when it was made.
Failing to explain reliance—why the complainant parted with money because of the representation.
Filing in the respondent’s city without showing that an essential element occurred there.
Providing selected screenshots while withholding the surrounding conversation.
Naming every company officer, relative, employee, or account owner without evidence of personal participation.
Giving inconsistent dates or loss amounts across the affidavit, demand letter, bank report, and annexes.
Submitting a check case without written notice and proof of actual receipt.
Ignoring a required Certificate to File Action from the barangay.
Assuming that an email, police blotter, or online report completed the prosecutor filing.
Missing a 10-calendar-day or 15-day reconsideration deadline.
Editing original files, deleting chats, or surrendering the only copy of a device or document.
Paying a fixer or using an unofficial filing address.
Signing a settlement, quitclaim, or affidavit of desistance without understanding its effect on the civil claim and criminal evidence.

When legal help is urgent

Seek a lawyer or law-enforcement assistance immediately when:

the electronic transfer has just occurred and funds may still be held;
the scammer still has access to your account, SIM, email, ID, or device;
electronic evidence or platform records may disappear;
the respondent is threatening, stalking, blackmailing, or pressuring you;
a prosecutor’s resolution or subpoena has already been received;
prescription or a reconsideration deadline may be near;
the loss is substantial, involves many victims, or crosses national borders;
the scheme concerns investments, securities, recruitment, real estate, corporate funds, or public money;
the wrong office may have been selected; or
a settlement or repayment proposal requires a waiver or desistance affidavit.

Qualified indigent persons may request assistance from the Public Attorney’s Office. The DOJ Action Center also receives requests for legal assistance and complaint referrals. Eligibility and the scope of representation must still be evaluated.

Frequently asked questions

Can I file without a lawyer?

Yes. A complainant may prepare and swear to a complaint-affidavit personally. However, the DOJ now requires prima facie evidence with reasonable certainty of conviction, so incomplete allegations or missing evidence can result in dismissal. Legal review is especially valuable for venue, cybercrime, check, investment, corporate, and prescription issues.

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

Yes, but an NBI or PNP investigation will usually be needed to identify the person behind the account. Give investigators every technical and transaction identifier you possess. Do not invent a name or assume that an account holder and the person communicating with you are the same.

Must I send a demand letter first?

It depends on the estafa theory. A demand is particularly important in misappropriation cases and for establishing receipt of notice in dishonored-check cases. Demand is not a substitute for proving deceit and is not universally required for every form of estafa. If funds or evidence may disappear, report to the bank and law enforcement before giving advance warning.

Can I file where I live?

Not automatically. You may file there only if an essential element of the offense occurred within that territorial jurisdiction. The places where messages were received, reliance occurred, funds were released, property was entrusted, or other criminal acts happened must be examined from the evidence.

Does repayment automatically dismiss the case?

No. Once a public offense is properly under prosecution, repayment, settlement, or an affidavit of desistance does not automatically require dismissal. It may affect the civil claim, the available evidence, or the prosecutor’s evaluation, depending on the facts. Do not sign documents stating that no crime occurred if that statement is untrue.

Can several victims file together?

Victims may coordinate their evidence and identify a common scheme, but each transaction must still be proved. The prosecutor determines whether complaints should be consolidated and whether the facts support separate offenses, conspiracy, economic sabotage, or another statutory charge.

How long will the case take?

The DOJ rules set periods for evaluation and resolution, but service of subpoenas, case build-up, complexity, motions, review, court filing, trial, and appeals can extend the overall process. Keep the docket number, monitor official notices, and update the prosecution office if your address, phone number, or email changes.
