Quick answer

File a sworn complaint-affidavit with the Office of the City Prosecutor or Provincial Prosecutor that has territorial jurisdiction over the place where the alleged fraud occurred. Attach the National Prosecution Service Investigation Data Form, witness affidavits, and evidence showing the misrepresentation or abuse of trust, your reliance or transfer of property, and the resulting loss.

For an online or bank-transfer scam, immediately report the disputed transaction through your bank or e-wallet provider’s official fraud channel before preparing the criminal complaint. A timely report may allow the institution to trace and temporarily hold funds, but recovery is not guaranteed.

A police or National Bureau of Investigation investigation can help identify an unknown offender, preserve electronic evidence, or build a complex case. It does not replace the prosecutor’s determination of whether charges should be filed in court. Filing a complaint also does not automatically cause an arrest, guarantee conviction, or assure repayment.

Is the incident legally estafa?

Estafa is not simply failure to pay a debt or keep a promise. Article 315 of the Revised Penal Code requires fraud committed through one of the means specified by law, together with damage or prejudice capable of monetary estimation. The principal forms commonly encountered are:

Estafa through false pretenses or deceit

This generally requires evidence that:

The respondent made a false representation or used a fraudulent act;
The deception occurred before or at the same time you parted with money or property;
You relied on it; and
You suffered damage because of that reliance.

Examples may include pretending to own property, operate a genuine business, possess authority to sell or invest, or conduct a transaction that did not exist. The precise representation matters. A complaint should state who said what, when and where it was said, why it was false, and how it induced the payment.

A lie made only after money was obtained ordinarily cannot be the deceit that induced the transfer. Likewise, later failure of a legitimate business or inability to perform a contract does not by itself prove that the person was already deceiving you when the transaction began. The Supreme Court has consistently required the deceit to precede or accompany the victim’s act of parting with money or property.

Estafa through misappropriation or conversion

This generally involves:

Money, goods, or other personal property received in trust, on commission, for administration, or under an obligation to deliver or return the same property;
Misappropriation, conversion, or denial of receipt;
Prejudice to another; and
A demand for return or accounting, as recognized in applicable decisions.

The legal character of the original transaction is crucial. Money received as a loan normally becomes the borrower’s property, creating an obligation to repay an equivalent amount. That is different from money received in trust or for a defined purpose with a duty to deliver or return it. A simple unpaid loan or contractual breach should not be converted into a criminal case without facts establishing deceit or abuse of confidence.

A written demand is valuable because it documents nonreturn, identifies the amount claimed, and may help show conversion. Although jurisprudence recognizes that demand under Article 315(1)(b) need not always be written, written proof avoids disputes about whether and when demand occurred.

Current amount thresholds

For most forms of estafa under Article 315—other than the separate check-specific penalty provision—the current penalties under Republic Act No. 10951 are based on the amount of fraud:

Amount of fraud	Statutory penalty
₱40,000 or less	Arresto mayor in its medium and maximum periods
Over ₱40,000 up to ₱1,200,000	Arresto mayor maximum to prisión correccional minimum
Over ₱1,200,000 up to ₱2,400,000	Prisión correccional minimum and medium
Over ₱2,400,000 up to ₱4,400,000	Prisión correccional maximum to prisión mayor minimum
Over ₱4,400,000	Maximum period of the preceding penalty, with the statutory increment for each additional ₱2,000,000, subject to the 20-year ceiling

Different and substantially higher penalty bands apply to estafa through postdating or issuing an unfunded check under Article 315(2)(d). The date of the offense, the exact mode of fraud, use of information and communications technology, and possible special laws can also change the penalty and procedure. The controlling text appears in Republic Act No. 10951, Section 85.

If the offense was committed by, through, or with information and communications technology, Section 6 of the Cybercrime Prevention Act may raise the prescribed penalty by one degree. This must be alleged and supported by the facts; an online conversation alone should not be treated mechanically as a cybercrime enhancement. See Republic Act No. 10175.

Fraud involving five or more persons, a corporation or association soliciting funds from the public, or member or depositor funds may require evaluation under the stricter rules on syndicated estafa. Do not label a case “syndicated” merely because several people participated; Presidential Decree No. 1689 has specific elements.

Act immediately if money was transferred electronically

For a recent bank, card, or e-wallet transaction:

Contact the originating institution through its verified 24/7 fraud-reporting channel.
Identify the transaction reference number, source and recipient accounts, amount, date, and time.
Ask the institution to secure the source account, trace the transaction, and initiate the disputed-transaction process.
Obtain a complaint or case reference number and preserve all acknowledgments.
Change compromised passwords and PINs, revoke unfamiliar devices, and enable multifactor authentication.
Report the incident to law enforcement, especially if the recipient is unknown or the funds moved through several accounts.

Under the Anti-Financial Account Scamming Act and BSP Circular No. 1215, covered institutions may initially hold disputed funds for up to five calendar days and, when legally justified, extend the holding so the total does not exceed 30 calendar days without a court extension. This is a tracing and verification mechanism—not an assurance that funds remain available or will be returned. Account owners are expected to report immediately and cooperate with verification. See the BSP’s AFASA law and implementing rules.

Never make a false disputed-transaction report. Malicious reporting that causes an unwarranted hold is itself punishable under the law.

Where to file

File with the prosecution office covering a place where an essential element of the offense occurred. Depending on the facts, this may be where:

The false representation was made or received;
Money or property was delivered;
Property entrusted to the respondent was converted or should have been returned; or
The resulting damage occurred.

Criminal venue is jurisdictional. The victim’s residence, the respondent’s residence, or the location of a bank account is not automatically the correct venue. Online transactions involving people, devices, banks, and communications in different places require particular care. State each material location in the complaint and consult the intended prosecutor’s office before filing if venue is uncertain.

Use the:

Office of the City Prosecutor for an offense committed within a city that has its own prosecution office; or
Office of the Provincial Prosecutor for an offense committed within a municipality under its territorial jurisdiction.

The prosecutor may endorse or refer a wrongly filed complaint, but a venue error can cause delay or dismissal. The governing rules on instituting criminal actions appear in the Revised Rules of Criminal Procedure.

When barangay conciliation may be required

A low-penalty dispute between parties actually residing in the same city or municipality may first fall within the Katarungang Pambarangay process. If it does, obtain the appropriate Certificate to File Action before proceeding.

Barangay conciliation generally does not cover offenses punishable by imprisonment exceeding one year or a fine exceeding ₱5,000, disputes involving parties from different cities or municipalities subject to limited exceptions, cases involving the government, and the other exclusions in Sections 408 and 412 of the Local Government Code. Because the applicable penalty depends on the precise charge—not merely the amount lost—ask the barangay or prosecutor’s receiving unit whether a certificate is required. See Republic Act No. 7160, Sections 408–412.

Prepare the complaint-affidavit

The affidavit should be factual, chronological, and based on personal knowledge. Include:

Your complete name, address, and contact details;
The respondent’s full name, aliases, last known address, account details, company affiliation, and other identifying information;
The date and place of each material event;
The exact representation, promise, instruction, or trust arrangement;
Why the representation was false or what duty to return or deliver existed;
How you relied on it;
Each payment or transfer, including amount, method, recipient, and reference number;
What happened after the transfer;
Demands made and the response, if any;
The total actual loss and how it was calculated;
The role of each respondent; and
The offense requested for investigation, while allowing the prosecutor to determine the legally proper charge.

Use numbered paragraphs. Identify each attachment by an annex mark and refer to it in the relevant paragraph. Do not copy accusations from another victim unless that person executes a separate affidavit or you personally witnessed the facts.

The affidavit must be signed under oath before a prosecutor, notary public, or other officer authorized to administer oaths. False material statements can expose the affiant to criminal liability.

Evidence to attach and preserve

Submit evidence that establishes every element of the suspected offense, not merely proof that payment was made.

Useful evidence may include:

Contracts, order forms, acknowledgment receipts, invoices, trust receipts, delivery records, or investment documents;
Bank statements, deposit slips, transfer confirmations, remittance records, and e-wallet transaction details;
Original checks, bank return slips, and proof of presentment;
Complete chat threads, emails, text messages, call logs, and voice messages;
Advertisements, listings, account profiles, usernames, URLs, and platform identifiers;
Proof concerning the claimed property, authority, business, license, registration, or transaction;
Demand letters and proof of actual delivery or receipt;
Witness affidavits;
Police, NBI, bank, platform, SEC, DTI, or other relevant records;
A table reconciling all payments and losses; and
Evidence connecting each named respondent to the scheme.

Keep the original files and devices. Export complete conversations when possible instead of relying only on cropped screenshots. Preserve dates, sender information, URLs, transaction identifiers, email headers, and file metadata. Make read-only backups and record how each file was obtained. Do not edit, enhance, impersonate anyone, access another person’s account, or attempt to obtain evidence unlawfully.

Electronic records and platform data may disappear. For an unknown or technically sophisticated offender, seek prompt assistance from the NBI Cybercrime Division or the NBI’s fraud-investigation service. The NBI also maintains an online complaint page, but confirm whether a personal appearance or sworn statement is still required.

Filing requirements

Under the current DOJ-NPS rules, prepare:

The original complaint-affidavit;
Two duplicate copies for the prosecution office;
One additional complete copy for each respondent;
A duly accomplished NPS Investigation Data Form;
Witness affidavits; and
Complete supporting evidence in corresponding sets.

Ask the receiving office about pagination, binding, electronic media, notarization, office-specific e-filing, and the current legal fee before submission. Electronic filing and virtual investigation are permitted as alternatives under the DOJ rules, but availability and instructions depend on the prosecution office. Do not assume that sending an affidavit to a general email address formally institutes the complaint.

Upon filing:

Present the complete sets to the receiving unit.
Pay only the prescribed fee through the authorized channel and obtain an official receipt.
Secure the NPS or investigation docket number.
Keep a stamped receiving copy and an exact copy of everything submitted.
Record all deadlines and update your address, phone number, and email if they change.

The DOJ publishes its current preliminary-investigation filing service, forms, and schedule of legal fees.

What happens after filing

The head of the prosecution office first checks whether the affidavit is sufficient in form and the evidence is complete. Missing evidence may be required before the complaint is docketed. Once assigned, the investigating prosecutor may recommend outright dismissal or issue a subpoena.

Where the respondent is entitled to participate, the respondent receives the complaint and is given an opportunity to submit a counter-affidavit and evidence. Under regular preliminary investigation, the hearing must allow the respondent at least 10 calendar days from receipt of the subpoena to submit the counter-affidavit. The prosecutor may conduct a physical or virtual clarificatory hearing and, in appropriate regular cases, require a reply and rejoinder.

The current evidentiary standard within the National Prosecution Service is prima facie evidence with reasonable certainty of conviction. The available testimonial, documentary, and real evidence must be admissible, credible, preservable for trial, and sufficient—if left uncontradicted—to establish all elements and the identity of the responsible person. The Supreme Court upheld this prosecutorial framework in 2025.

If the required standard is met, the prosecutor recommends filing an Information in court. If not, the complaint is dismissed, although a dismissal may be without prejudice to refiling when lawful and supported by genuinely new or additional evidence. See DOJ Department Circular No. 15, series of 2024.

Even after an Information is filed, the judge independently determines whether a warrant of arrest should issue. A private complainant cannot personally arrest, detain, threaten, or seize property from the respondent.

Which investigation procedure applies?

The prescribed penalty—not simply the amount claimed—determines the DOJ-NPS track:

Summary investigation: Generally for offenses punishable by one day to one year, a fine regardless of amount, or both. It is ordinarily resolved from the complainant’s evidence without a counter-affidavit. No motion for reconsideration is entertained under this track.
Expedited preliminary investigation: Generally for offenses punishable by one year and one day to six years and exclusively within first-level court jurisdiction. The prosecutor should resolve the matter within 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: Generally for offenses punishable by at least six years and one day, regardless of fine, and for certain offenses assigned by law to the Regional Trial Court. The investigating prosecutor ordinarily has 60 calendar days from assignment to resolve the complaint, with a maximum 30-day extension in specified complex circumstances. An aggrieved party may file a motion for reconsideration within 15 days from receipt of the resolution.

These periods govern prosecutorial processing and remedies; they are not promises that the entire criminal case will end within those periods. Review or appeal routes depend on which prosecution office issued the resolution, the court having jurisdiction, and whether an Information has already been filed. Obtain legal advice immediately upon receiving an adverse resolution because the periods are short and are generally counted in calendar days.

The Supreme Court has recognized both Department Circular No. 15 and the companion rules for summary and expedited investigations, discussed in its official decision concerning Department Circular No. 28.

Special rule for dishonored checks

A dishonored check does not automatically prove estafa.

For estafa under Article 315(2)(d), the prosecution must establish that the check was issued as the inducing cause for the victim to part with money or property, together with the other required elements. A check issued only for a pre-existing debt generally does not supply that inducement.

Article 315 also provides a three-day period from receipt of notice of dishonor for purposes of its statutory prima facie rule on deceit. This should not be confused with Batas Pambansa Blg. 22, which is a separate offense. Under BP 22, a check can cover a pre-existing obligation, and its statutory presumption involves presentment within 90 days and failure to pay or arrange full payment within five banking days after actual receipt of notice of dishonor. Proof that the drawer actually received written notice is therefore important. See Batas Pambansa Blg. 22.

Preserve the original check, bank return slip, written notice, affidavit of service, courier tracking, acknowledgment, and other proof of actual receipt. Have counsel assess whether the facts support estafa, BP 22, both distinct offenses, or only civil collection.

Criminal complaint and recovery of money

When a criminal action is instituted, the civil action to recover civil liability arising from the offense is generally deemed instituted with it unless the complainant waives it, reserves the right to file it separately, or has already filed it. Recovery still depends on the evidence, the court’s judgment, and the availability of assets.

A prosecutor’s dismissal does not necessarily decide every possible contractual or civil remedy. Conversely, winning a civil collection case does not establish criminal fraud. Have counsel evaluate civil prescription, provisional remedies, asset preservation, and whether a separate action is appropriate before making a reservation.

Settlement, repayment, an affidavit of desistance, or withdrawal by the complainant does not automatically erase a completed public offense. It may affect civil liability, evidence, or prosecutorial decisions, but control of a criminal action belongs to the State once instituted.

Common mistakes to avoid

Treating every unpaid debt, failed investment, or broken promise as estafa;
Omitting the exact false representation or trust obligation;
Failing to show that deceit preceded or accompanied the payment;
Naming company officers solely because of their titles, without describing their acts;
Filing in the victim’s location without establishing that an element occurred there;
Submitting cropped screenshots without the complete conversation or account identifiers;
Losing original checks, devices, receipts, or transaction records;
Ignoring barangay conciliation when it is legally required;
Sending a demand without preserving proof of receipt;
Waiting for the respondent to disappear before reporting the transaction;
Posting accusations and personal information publicly instead of preserving them for authorities;
Exaggerating the amount, adding unsupported respondents, or submitting hearsay as personal knowledge; and
Missing a motion-for-reconsideration or prescription deadline.

When legal help is urgent

Consult a Philippine lawyer promptly when:

The proper venue is uncertain or several cities or provinces are involved;
The respondent’s identity or address is unknown;
The transaction was online, cross-border, or used several financial accounts;
The amount is substantial or the scheme has multiple victims;
A corporation, investment solicitation, cooperative, bank, or public funds are involved;
Five or more coordinated participants may be operating through an association;
The respondent is disposing of assets, threatening witnesses, or destroying evidence;
The prosecutor requires case build-up or rejects the complaint at intake;
A resolution has been received and a reconsideration or review period is running;
Prescription may be close;
The same facts may involve BP 22, cybercrime, access-device fraud, AFASA, securities, or other special laws; or
You need to decide between criminal, civil, administrative, and regulatory remedies.

Frequently asked questions

Do I need a lawyer to file?

A complainant may execute and file a complaint-affidavit without private counsel. A lawyer is strongly advisable when the facts, venue, legal classification, electronic evidence, amount, or possible appeal is complicated. Qualified persons may also inquire about assistance from the Public Attorney’s Office or an IBP legal-aid office, subject to their eligibility and case-assessment rules.

Can I file if I do not know the scammer’s real name?

You can report the incident to the NBI or police with the account numbers, usernames, telephone numbers, URLs, transaction references, photographs, and other identifiers. A formal prosecutor’s complaint requires enough information to identify and notify the respondent; investigation may be needed first. Do not guess a person’s identity.

Is a demand letter always required?

It is especially useful in misappropriation and dishonored-check cases and may be legally significant depending on the charge. Its necessity and required contents differ by offense. Use a traceable method and preserve proof of actual receipt.

Can I file estafa for an unpaid loan?

Usually not on nonpayment alone. The complaint must show legally sufficient deceit at the beginning of the transaction or another statutory mode of estafa. A genuine loan ordinarily creates a civil obligation to repay.

What if the respondent returned part of the money?

Partial or later payment does not automatically erase criminal liability that was already completed. It may affect the amount of actual loss, civil liability, intent, or the evaluation of the evidence. Disclose every payment accurately.

Will the respondent be arrested immediately?

No. The prosecutor first evaluates the evidence. If an Information is filed, the judge independently determines whether a warrant is warranted. Warrantless arrest is allowed only under the limited circumstances provided by law.

How long do I have to file?

The prescriptive period depends on the exact offense and prescribed penalty. For Revised Penal Code offenses, the possible periods include five, 10, 15, or 20 years, with special rules on when the period begins, is interrupted, and resumes. The date of discovery, filing history, amount, mode of estafa, cybercrime enhancement, and applicable special law may all matter. Do not calculate prescription from a general online table; obtain case-specific advice and file without unnecessary delay.

Does filing guarantee that I will recover the money?

No. It begins an official evaluation and may lead to prosecution and a civil award, but recovery depends on proof, judgment, available assets, and enforcement. Immediately reporting an electronic transfer may improve the possibility of tracing funds, but no agency or institution can promise recovery.
