Quick answer

To start an estafa case, file a sworn complaint-affidavit with the Office of the City or Provincial Prosecutor that has territorial jurisdiction over the place where the fraud—or an essential part of it—occurred. Attach witness affidavits and evidence proving the specific deception or abuse of confidence, your reliance or entrustment, the respondent’s acts, and your financial loss.

You may first seek investigative assistance from the police or National Bureau of Investigation (NBI), especially when the offender’s identity is uncertain or the fraud occurred online. A police blotter, platform report, or NBI complaint, however, does not necessarily replace filing with the proper prosecution office.

Act promptly. Notify the bank or e-wallet involved, preserve electronic evidence, and determine whether barangay conciliation is required. Prescription, venue, the correct offense, and the applicable DOJ investigation procedure depend on the amount, dates, documents, method used, and any special law involved.

Confirm that the facts may constitute estafa

“Fraud” is a broad description, not a single criminal charge. Estafa is punished under Article 315 of the Revised Penal Code. Losing money, being unable to collect a debt, or dealing with a broken promise does not automatically establish estafa.

Estafa through false pretenses or deceit

A complaint under Article 315(2)(a) generally needs evidence that:

The respondent made a false pretense, fraudulent representation, or similar deceit.
The deceit occurred before or at the same time as the transaction.
You relied on it and were thereby induced to part with money or property.
You suffered damage.

Examples may include pretending to own property, falsely claiming authority to sell or invest, using a fictitious identity, or representing that a nonexistent business or transaction is genuine. The Supreme Court discusses these elements in Dulay v. People.

The timing matters. A lie told only after the money was voluntarily delivered may not satisfy this mode of estafa unless other facts establish a different punishable scheme.

Estafa through misappropriation or conversion

A complaint under Article 315(1)(b) generally requires proof that:

The respondent received money, goods, or personal property in trust, on commission, for administration, or under an obligation to deliver or return the same.
The respondent misappropriated or converted it, or denied receiving it.
Another person suffered prejudice.
A demand for return or accounting was made.

Conversion means using or disposing of another person’s property as if it were one’s own or for a purpose different from what was agreed. Mere inability or failure to return property does not by itself prove conversion. These principles are explained in Cheng v. People.

If safe and appropriate, make a clear written demand and retain proof that it was received. A demand helps establish default, refusal, or failure to account, but it cannot transform an ordinary unpaid loan into estafa.

A debt or contract dispute may be civil, not criminal

The key question is whether the loss resulted from legally punishable deceit or abuse of confidence—not simply nonpayment or poor performance. The Supreme Court has distinguished estafa from a contractual breach: when the source of the obligation is merely a loan, sale, or other contract and criminal fraud is not proved, collection may require a separate civil case.

Do not exaggerate a civil disagreement to pressure someone into paying. State only facts you can support through admissible evidence.

Dishonored checks require separate analysis

A bounced check does not automatically prove estafa. For estafa under Article 315(2)(d), the check generally must have induced the victim to part with money or property when the obligation was contracted. A check issued only to pay an existing debt ordinarily does not supply the required prior or simultaneous deceit.

The same check may raise a separate issue under Batas Pambansa Blg. 22. BP 22 has distinct requirements, including timely presentment and written notice of dishonor with proof of receipt. Failure to pay or arrange payment within five banking days after receipt of notice is material. Preserve the original check, deposit slip, return memo, written demand, and proof of delivery.

Online fraud may involve additional laws

If estafa was committed by, through, and with information and communications technology, Section 6 of the Cybercrime Prevention Act may apply and can increase the penalty by one degree. Separate offenses such as computer-related fraud or identity theft require their own statutory elements.

Not every scam discussed through chat or social media automatically becomes “computer-related fraud.” That offense ordinarily involves unauthorized input, alteration, or deletion of computer data, or interference with a computer system. The prosecutor must determine the correct charge from the actual conduct and evidence.

Act immediately if money was just transferred

Contact the sending bank, card issuer, remittance company, or e-wallet through its verified fraud channel. Ask whether a recall, hold, dispute, or account-preservation procedure is available. Record the case number, time, representative’s name, and the institution’s response. Recovery is not guaranteed, but delay may allow the funds to be moved.

For a BSP-supervised institution, complain first through the institution’s Financial Consumer Protection Assistance Mechanism. An unresolved service complaint may then be escalated through the BSP Consumer Assistance Mechanism. This consumer process is separate from a criminal complaint.

Change compromised passwords, revoke unknown sessions, enable multifactor authentication, and inform the relevant provider of any stolen identity or account. Do not send additional “release,” “verification,” or “recovery” payments.

Preserve evidence before accounts or messages disappear

Keep the original devices and native electronic records whenever possible. Preserve:

Complete chats, emails, SMS messages, call logs, and voice messages—not only selected screenshots
Profile names, account IDs, usernames, phone numbers, email addresses, URLs, QR codes, and wallet addresses
Advertisements, listings, websites, livestreams, and representations you relied on
Contracts, receipts, invoices, acknowledgments, delivery records, and identification documents supplied by the respondent
Bank statements, transfer confirmations, transaction reference numbers, deposit slips, remittance forms, and return memos
The exact dates, times, locations, and participants for each communication and payment
Written demands and proof of receipt or attempted delivery
Names and contact details of witnesses and other victims
Platform, bank, police, NBI, or regulatory complaint reference numbers

Export conversations using the platform’s available tools. Save emails with full headers and retain files in their original formats. Make read-only backup copies, but do not edit the originals. For screenshots, capture the account identifier, date, time, and surrounding conversation. The Rules on Electronic Evidence require electronic evidence to be properly identified and authenticated.

Do not secretly access another person’s account, impersonate the suspect, alter records, or arrange an entrapment operation without law-enforcement guidance.

Where to file

The proper prosecution office

File with the Office of the City Prosecutor or Office of the Provincial Prosecutor whose territorial jurisdiction covers the proper venue. Venue is where the offense, or an essential ingredient of it, occurred. Depending on the facts, relevant places may include where the deceit was communicated and relied upon, where property was delivered, where entrusted property was converted, or where the resulting damage occurred.

Do not assume that your home address alone establishes venue. For transactions spanning several cities, online payments, or dishonored checks, ask the receiving prosecutor or a lawyer to review venue before filing. A case filed in the wrong place may be referred, delayed, or dismissed.

Police or NBI assistance

The police or NBI can take a report, identify suspects, interview witnesses, secure records through lawful process, and refer an investigated case to prosecutors. For online incidents, options include:

The NBI Online Complaint portal
The NBI’s Cybercrime Division assistance service
The NBI’s Anti-Fraud Division assistance service
The DOJ’s cybercrime-reporting guidance

Use only current contact details shown on official government websites. Be cautious of people who claim they can recover money for an advance fee.

When barangay conciliation may be required

Katarungang Pambarangay can be a condition before filing certain disputes when the parties actually reside in the same city or municipality. It generally does not cover an offense punishable by imprisonment exceeding one year or a fine exceeding ₱5,000, and statutory exceptions apply.

Because estafa involving not more than ₱40,000 ordinarily carries a maximum penalty not exceeding one year, a low-value case between residents of the same city or municipality may require barangay proceedings and a Certificate to File Action—unless an exception applies. Different residences, urgent legal action, detention, public-officer cases, and an increased cybercrime penalty can change the analysis. See Sections 408 and 412 of the Local Government Code.

Confirm this before filing. Do not go through barangay conciliation when doing so would create an immediate safety risk without first obtaining legal or law-enforcement advice.

Prepare the complaint-affidavit

Write in numbered paragraphs and chronological order. The affidavit should identify:

Your complete name, address, and contact details
Each respondent’s complete name and last known address, if known
The precise dates and places of material acts
The representation, promise, or entrustment involved
Why the representation was false, or how the entrusted property was converted
What you relied upon and why you released the money or property
The amount and method of every payment or delivery
What happened afterward, including demands and responses
The specific damage you suffered
The participation of each respondent, rather than treating everyone as automatically liable
The attached evidence and what each attachment proves

Avoid conclusions such as “the respondent is obviously a scammer” without stating the underlying facts. Quote only statements you can reproduce accurately. Do not conceal refunds, partial performance, contrary messages, settlements, or documents that materially affect the transaction.

Attach separate sworn affidavits from witnesses with personal knowledge. A corporate complainant should include proof that its representative is authorized to act.

The complaint-affidavit must be subscribed and sworn before a prosecutor or other government official authorized to administer oaths—or, when those officials are absent or unavailable, before a notary public—following the applicable DOJ rules. Never sign a sworn affidavit containing facts you know are false.

Assemble the filing packet

Under the 2024 DOJ-NPS rules, the standard packet generally includes:

The original complaint-affidavit
Two duplicate copies for the prosecution office
One additional complete copy for every respondent
The required NPS Investigation Data Form
Witness affidavits
Legible, organized supporting evidence
A Certificate to File Action, when barangay conciliation applies
Proof of authority if filing for a company or another authorized complainant

Number and label attachments consistently—for example, Annex “A,” “B,” and “C”—and prepare an index for a large record. Bring a valid government-issued ID and the originals for comparison, but retain custody unless the office lawfully receives them and gives you an inventory or receipt.

Requirements may vary for referrals by law-enforcement agencies, juridical persons, minors, voluminous records, electronic filing, and particular prosecution offices. Verify the office’s current receiving instructions before submission.

File and document receipt

Submit the complete packet to the docket or receiving section of the proper prosecution office. Obtain a stamped receiving copy showing the date, office, and docket or reference number. Keep the receipt and a complete copy of everything filed.

If the office identifies missing documents, ask for a written checklist where available. Supply the material promptly. A complaint may remain undocketed or be closed when essential evidence is incomplete.

Filing promptly is important because estafa has no single prescriptive period. The period depends on the applicable penalty, which in turn depends on the amount, mode, date, and other circumstances. Filing the complaint with the prosecution office generally interrupts prescription under Article 91 of the Revised Penal Code, but special laws may have different rules. Do not wait for the last possible day.

How the amount affects the investigation procedure

Republic Act No. 10951 adjusted Article 315’s value brackets:

Amount of fraud	General DOJ investigation track
Not more than ₱40,000	Ordinarily summary investigation
Over ₱40,000 but not more than ₱1,200,000	Ordinarily expedited preliminary investigation
Over ₱1,200,000 but not more than ₱2,400,000	Ordinarily expedited preliminary investigation
Over ₱2,400,000	Ordinarily regular preliminary investigation

These are general guides, not automatic classifications. Separate transactions may constitute separate counts rather than one aggregated amount. Cybercrime allegations, complex crimes, special laws, and the court with jurisdiction can alter the track.

For amounts over ₱4,400,000, Article 315 provides additional penalty increments for each additional ₱2,000,000, subject to a statutory maximum. The amount affects the penalty; it does not excuse the need to prove every element of estafa.

What happens after filing

The DOJ applies a uniform evidentiary standard: prima facie evidence with reasonable certainty of conviction. The evidence must be admissible, credible, capable of preservation and presentation at trial, and sufficient—if left uncontroverted—to establish every element and identify the responsible person. The Supreme Court upheld the validity of this standard in Meking v. Secretary of Justice.

Summary investigation

For offenses punishable by one day to one year, a fine, or both, summary investigation is generally ex parte. The prosecutor evaluates the complete complaint record and either recommends dismissal or prepares an information for court. The investigating prosecutor is directed to resolve the case immediately upon receiving the complete records. No motion for reconsideration is allowed under DOJ Department Circular No. 028.

Expedited preliminary investigation

For covered offenses punishable by one year and one day to six years:

The assisting prosecutor generally evaluates form and completeness within three calendar days.
If case build-up is necessary, the rules allow up to 20 calendar days from evaluation.
If a hearing is required, the prosecutor generally issues a subpoena within five calendar days after receiving the complete record, setting a hearing no later than 15 calendar days from receipt of that record.
No reply-affidavit or rejoinder-affidavit is ordinarily entertained.
The prosecutor generally has 20 calendar days from receipt of the complete case record after case build-up and docketing to resolve it.
An aggrieved party may move for reconsideration within 10 calendar days from receipt of the resolution.

Regular preliminary investigation

For offenses carrying a prescribed penalty of at least six years and one day:

The investigating prosecutor generally acts within five calendar days after receiving the complete record, either recommending dismissal or issuing subpoenas.
The hearing is generally set within 30 calendar days from receipt of the complete record.
A respondent must receive the subpoena and complaint at least 10 days before the submission date.
When allowed, a reply or rejoinder must generally 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 maximum 30-day extension in specified cases.
A motion for reconsideration must generally be filed within 15 days from receipt of the resolution.

These are DOJ processing periods, not promises that the entire criminal case will finish within those periods. Service problems, incomplete evidence, multiple respondents, reconsideration, review, and court proceedings can extend the timeline. The controlling texts are DOJ Department Circular No. 015 and Department Circular No. 028, available through the DOJ’s issuances page.

If the complaint is dismissed

Read the resolution immediately and note the date you received it. Determine whether the case was handled through summary, expedited, or regular investigation because the available remedies and deadlines differ.

A dismissal may be without prejudice when genuinely new or additional evidence can be produced after further case build-up. Regular preliminary-investigation resolutions may also be subject to a petition for review under applicable DOJ rules. Do not repeatedly refile the same unsupported allegations or miss a 10- or 15-day remedy period. Obtain legal advice as soon as the resolution arrives.

Recovery of money or property

A criminal complaint does not guarantee reimbursement. When a criminal action is instituted, the civil action for liability arising from the charged offense is generally deemed included unless it was waived, reserved, or filed earlier, as provided in Rule 111.

A separate collection, rescission, damages, or other civil action may be appropriate when the obligation is contractual or when strategic reasons justify a separate remedy. Filing overlapping cases without understanding Rule 111 may create procedural complications. Ask counsel to assess civil recovery, attachment, filing fees, and whether any prior settlement or civil case affects the criminal complaint.

Common mistakes to avoid

Treating every unpaid debt or failed investment as estafa
Failing to identify the exact false statement or act of conversion
Omitting when and where the material acts occurred
Filing in a location with no connection to an element of the offense
Submitting cropped screenshots without account identifiers or context
Deleting chats or discarding the original phone after printing screenshots
Naming corporate officers solely because of their titles, without describing personal participation
Combining separate transactions without showing how they form one scheme
Relying only on a police blotter or platform report
Sending a demand but keeping no proof of receipt
Ignoring barangay conciliation when it applies
Missing a subpoena, hearing, or reconsideration deadline
Paying a supposed fixer, investigator, or “recovery agent”
Posting accusations publicly in a way that creates separate legal or safety problems

When legal or law-enforcement help is urgent

Seek prompt help when:

The transfer happened recently and funds may still be traceable
Accounts, websites, or messages are being deleted
Several victims or large amounts are involved
The respondent used a false identity or is outside the Philippines
Your identity, SIM, bank account, or device was compromised
You received threats, coercion, or demands for further payment
The case involves investments, securities, recruitment, access devices, falsified documents, or corporate funds
Venue, barangay conciliation, prescription, or the correct charge is uncertain
A subpoena or adverse resolution has already been received

Report immediate threats or ongoing unlawful access to the police. For legal assistance, consider a private criminal-law practitioner, an Integrated Bar of the Philippines legal-aid office, a qualified law-school legal clinic, or the Public Attorney’s Office if its eligibility and representation rules are met.

Frequently asked questions

Do I need a lawyer to file?

A lawyer is not generally required to submit your own complaint-affidavit. Legal help is strongly advisable when the amount is substantial, several respondents or offenses are involved, the respondent is unidentified, or venue and prescription are disputed.

Must I send a demand letter first?

Not for every form of estafa. A written demand is particularly important in misappropriation or conversion cases and in dishonored-check matters. For deception-based estafa, the central issue is usually the false representation made before or during the transaction. Preserve proof of receipt whenever a demand is sent.

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

You may report the incident to the NBI or police for identification and lawful evidence gathering. Provide every available digital and financial identifier. A prosecutable case ultimately requires reliable evidence identifying the responsible person; the account holder and the person who committed the deception are not necessarily the same.

Can the complaint be filed online?

The DOJ rules recognize e-filing and virtual proceedings as alternatives, but availability and authorized addresses depend on the prosecution office and an official order or procedure. Confirm directly with the correct office. An NBI online report is not automatically the same as filing a complaint-affidavit with the prosecutor.

Will the respondent be arrested immediately?

Ordinarily, filing a complaint does not result in immediate arrest. The prosecutor first evaluates the evidence. If an information is filed in court, the judge independently determines whether probable cause exists for a warrant. Warrantless arrest and inquest apply only under legally permitted circumstances.

How long will the case take?

The DOJ rules contain periods for evaluation and resolution, but they do not fix the duration of the later court case. Completeness of evidence, service of subpoenas, the number of respondents, motions, review, and trial requirements affect the actual timeline.

Can an affidavit of desistance end the case?

Not automatically. Estafa is prosecuted in the name of the People of the Philippines. A settlement, repayment, or desistance may affect the evidence or civil liability, but it does not necessarily compel dismissal once a public offense has been established.
