Quick answer

To start an estafa case, file a sworn complaint-affidavit and supporting evidence 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. You may first seek investigative assistance from the Philippine National Police (PNP) or National Bureau of Investigation (NBI), especially when the offender is unknown, the transaction happened online, or records must be obtained from banks, platforms, or telecommunications providers.

A failed investment, unpaid loan, breached contract, or bounced check is not automatically estafa. Your evidence must establish the particular form of fraud punished by Article 315 of the Revised Penal Code. The prosecutor—not the complainant—ultimately determines the proper charge and whether the evidence meets the current DOJ standard of prima facie evidence with reasonable certainty of conviction.

When the facts may constitute estafa

The most common forms are:

Estafa by false pretenses or deceit

Generally, the evidence must show that:

The respondent made a false representation or used a fraudulent device;
The deception occurred before or at the time you parted with money or property;
You relied on it; and
You suffered damage as a result.

Examples may include using a fictitious identity, pretending to own property, inventing a business or transaction, or falsely claiming authority, qualifications, credit, or agency. The false statement must have induced the payment or transfer. A lie made only after a valid debt or contract already existed ordinarily does not satisfy this form of estafa. See Article 315 as amended by Republic Act No. 10951 and the Supreme Court’s discussion of the elements in Dulay v. People.

Estafa by misappropriation or conversion

Generally, the evidence must show that:

The respondent received money, goods, or other personal property in trust, on commission, for administration, or under an obligation to deliver or return it;
The respondent misappropriated, converted, or denied receiving it; and
Someone suffered prejudice.

The arrangement must ordinarily transfer juridical possession—not merely physical custody. For example, an employee who has only material possession of an employer’s money may have committed another offense, such as qualified theft, rather than estafa. The Supreme Court explains this distinction in Cambri v. People.

A written demand is useful evidence of non-return or conversion, but the Supreme Court has clarified that demand is not invariably an essential element. Its necessity and significance depend on the particular allegations and evidence. Preserve any demand and proof that the respondent received it.

Bounced checks require separate analysis

A dishonored check does not by itself prove estafa. For estafa under Article 315(2)(d), the check must generally have been part of the deceit that induced the complainant to part with money or property. A check issued only to pay or secure a pre-existing obligation ordinarily cannot be the inducing cause of that earlier transfer.

Article 315(2)(d) also has its own penalty structure and a statutory rule concerning failure to fund the check within three days after receipt of notice of dishonor. A possible violation of Batas Pambansa Blg. 22 is a separate offense with different elements, notice requirements, and periods. Have a lawyer examine the check, purpose of issuance, date of delivery, bank return slip, and proof of receipt of the notice of dishonor.

Online fraud may carry additional consequences

When estafa is committed by, through, and with the use of information and communications technology, Section 6 of the Cybercrime Prevention Act may apply. The prescribed penalty is then one degree higher, and cases under the Act fall within Regional Trial Court jurisdiction. Online conduct may also support other charges, such as computer-related fraud or identity theft, depending on what the offender actually did.

Because an ordinary failed online sale is not automatically “computer-related fraud,” let the prosecutor determine whether the case should be charged as estafa in relation to Section 6, a distinct cybercrime offense, or another crime.

Act immediately if money was transferred electronically

Contact the sending bank, e-wallet, or payment provider through its official fraud channel as soon as possible. Obtain a case or reference number and ask whether the transaction can be traced, recalled, disputed, or temporarily held. Do the same with the receiving institution if its official complaint channel is available.

The Anti-Financial Account Scamming Act and BSP Circular No. 1215 provide mechanisms for temporary holding and coordinated verification of disputed transactions. These mechanisms do not guarantee recovery, so speed matters.

If an account, email address, or device was compromised, also:

Change passwords using a safe device;
Sign out other sessions and enable multi-factor authentication;
Notify the affected platform;
Preserve security alerts and login records; and
Do not delete the original conversations or reset the affected device until relevant evidence has been copied or examined.

Where to file

Office of the City or Provincial Prosecutor

The practical filing point is usually the prosecution office covering the place where the offense or an essential ingredient occurred. Under Rule 110, criminal actions are generally instituted where the offense was committed or where any essential ingredient occurred. In Manila and other chartered cities, complaints are filed with the prosecutor unless the city charter provides otherwise. See Rules 110 to 112 of the Rules of Criminal Procedure.

Venue is fact-sensitive. Relevant places may include where:

The fraudulent representation was made or received;
The complainant relied on it and delivered money or property;
The respondent received or converted entrusted property; or
The resulting damage occurred.

Your residence alone does not necessarily establish venue. State the exact locations of the communications, agreement, delivery, deposit, withdrawal, dishonor, and discovery of the fraud.

PNP or NBI

A police or NBI report can help develop the case but is not ordinarily a substitute for the complaint-affidavit required by the prosecution office.

Seek investigative assistance when:

The offender’s real name or address is unknown;
The scheme used multiple bank, e-wallet, phone, or social-media accounts;
Digital evidence may disappear;
Subscriber, platform, bank, or IP records are needed;
There are multiple victims; or
The activity may be organized or cross-border.

For computer-related cases, the NBI’s official process is described in its Citizen’s Charter for investigative assistance to computer-crime victims. The NBI regional and district office directory can help locate the appropriate office. The PNP and NBI are the designated law-enforcement authorities under Section 10 of the Cybercrime Prevention Act.

Barangay conciliation may be required in limited cases

Prior barangay conciliation may be a condition before filing when the parties are natural persons actually residing in the same city or municipality and the dispute falls within the lupon’s authority.

This is most likely to matter in ordinary estafa cases involving no more than ₱40,000, because the corresponding imprisonment does not exceed one year. Exceptions include offenses punishable by imprisonment exceeding one year, disputes involving parties from different cities or municipalities subject to the statutory adjoining-barangay exception, an accused already in detention, and situations where delay may cause the action to prescribe.

The controlling provisions are Sections 408 and 412 of the Local Government Code. If applicable, obtain the barangay certification authorizing the filing of the complaint. Do not assume that a police blotter replaces this certification.

Evidence to preserve

Build the file around the elements of the suspected offense, not merely around proof that you lost money.

Identity and contact information

Preserve:

The respondent’s full name, aliases, address, phone numbers, email addresses, and known workplace;
Account names, unique profile IDs, usernames, URLs, and seller-page details;
Bank or e-wallet account name and masked account number;
Copies of identification or business documents voluntarily provided during the transaction; and
Information connecting the respondent to the account or representation used.

Do not unlawfully access another person’s account or device to obtain evidence.

Proof of the representation and reliance

Keep:

Entire chat threads, emails, text messages, voice messages, and call logs;
Advertisements, listings, proposals, contracts, invoices, receipts, and order confirmations;
Photographs, videos, presentation materials, or credentials shown to you;
Proof that a claimed property, authority, qualification, or transaction was false;
A dated chronology identifying each representation and your response; and
Evidence showing that you paid because of the representation.

For digital evidence, retain the original device and native files where possible. Capture the account name, URL, date, and time. Avoid relying only on cropped or edited screenshots. Export complete conversations and make secure backups.

Proof of payment, delivery, and damage

Collect:

Deposit slips and transfer confirmations;
Bank or e-wallet statements;
Check images, return slips, and bank notices;
Delivery receipts and acknowledgments;
Serial numbers or descriptions of property delivered;
An itemized computation of the loss; and
Proof of any partial refund or recovered property.

Whenever possible, request official or certified transaction records from the institution concerned.

Proof of entrustment and conversion

For abuse-of-confidence cases, preserve:

Trust receipts, agency or commission agreements, consignment records, liquidation documents, or written instructions;
Proof of the duty to deliver, account for, or return the property;
Accounting records showing the shortage or non-remittance;
Demands and proof of service; and
Replies, admissions, inconsistent explanations, or refusal to account.

Witness evidence

Identify every person who personally saw or heard a material event. Each witness should prepare a separate affidavit limited to facts within that person’s knowledge. Avoid identical, copied narratives that obscure who actually witnessed each event.

How to prepare the complaint-affidavit

Write the affidavit in chronological, numbered paragraphs. It should ordinarily include:

Your full name, address, and relevant personal or representative capacity;
The respondent’s full name, aliases, and last known address;
The date and place of each important event;
The exact representation, act of entrustment, or fraudulent device used;
Why the representation was false or how the property was converted;
How and why you relied on the representation;
What money or property you delivered, including amounts and dates;
The damage suffered;
Demands made, responses received, and partial payments, if any;
The names and roles of witnesses; and
A list of attached evidence, marked systematically as annexes.

State facts rather than simply saying, “The respondent committed estafa.” Explain who did what, when, where, how, and with what result. Do not exaggerate, conceal refunds, or include statements you cannot truthfully swear to.

The complaint-affidavit must be sworn before a prosecutor or another government official authorized to administer oaths or, when they are unavailable, a notary public. Do not sign it in advance unless instructed by the official who will administer the oath.

Filing requirements

Under the DOJ’s current rules, the standard filing set consists of:

The original complaint-affidavit;
Two duplicate copies for the official file;
One additional set for each respondent;
A completed NPS Investigation Data Form;
Witness affidavits; and
All supporting documentary, digital, and object evidence.

Prepare complete, readable, identically indexed sets. Bring a government-issued ID and proof of authority if filing for a corporation, association, estate, minor, or another person. Ask the receiving office about its current local checklist, accepted media for electronic evidence, office hours, and any authorized electronic-filing process before submission.

The controlling procedures are in DOJ Department Circular No. 015, series of 2024 and DOJ Department Circular No. 028, series of 2024.

After filing:

Obtain and keep the NPS docket number and stamped receiving copy.
Record the filing date and the contact details of the prosecution office.
Monitor notices sent to your address, email, or counsel.
Attend any required hearing with the original evidence.
Update the office promptly if your contact details change.
Keep every subpoena, order, registry receipt, email, and resolution.

Which prosecution procedure applies?

For ordinary estafa under Article 315—excluding the special check-estafa penalties, cybercrime treatment, syndicated estafa, and complex offenses—the amount generally affects the prosecution track:

Amount of alleged fraud	Ordinary Article 315 penalty bracket	Usual DOJ-NPS track
₱40,000 or less	Arresto mayor in its medium and maximum periods	Summary investigation
Over ₱40,000 up to ₱1,200,000	Arresto mayor maximum to prisión correccional minimum	Expedited preliminary investigation
Over ₱1,200,000 up to ₱2,400,000	Prisión correccional minimum and medium	Expedited preliminary investigation
Over ₱2,400,000	Prisión correccional maximum to prisión mayor minimum, with statutory increases for higher amounts	Regular preliminary investigation

These classifications may change if another law or offense applies. Estafa through a worthless check under Article 315(2)(d) has separate, substantially higher penalty brackets. Cybercrime treatment, falsification, syndicated estafa, multiple counts, or another special law can also affect the procedure and court.

Summary investigation

For offenses punishable by up to one year, summary investigation is an ex parte review of the complaint and its attachments. The prosecutor may recommend dismissal or prepare an information based on that record. DOJ Circular No. 028 does not allow a motion for reconsideration in summary-investigation cases.

Expedited preliminary investigation

For qualifying first-level-court offenses punishable by one year and one day up to six years, the prosecutor may resolve the case on the complete record or issue a subpoena for an expedited preliminary investigation. No reply-affidavit or rejoinder-affidavit is allowed. If the resolution is adverse, a motion for reconsideration must be filed within 10 calendar days from receipt.

Regular preliminary investigation

Regular preliminary investigation applies to offenses punishable by at least six years and one day and to cases legally cognizable by the Regional Trial Court. The respondent generally receives the complaint and an opportunity to submit counter-affidavits. Clarificatory proceedings, including authorized virtual proceedings, may follow.

An aggrieved party may file a motion for reconsideration within 15 days from receipt of the regular preliminary-investigation resolution. Further review is governed by separate DOJ appeal rules.

Because these periods run from receipt and can be lost quickly, record the exact date, time, and manner in which the resolution was received.

What happens after the prosecutor acts?

If the prosecutor finds the required evidence, an information is prepared and filed in the proper court with the approval of the head of the prosecution office. The judge independently evaluates whether judicial probable cause exists and whether to issue a warrant, summons, or another appropriate order. Filing a complaint does not automatically result in arrest.

If the complaint is dismissed, read the entire resolution immediately. Determine which DOJ track applied before choosing a remedy. A dismissal may sometimes be without prejudice to refiling after additional case build-up, but that does not stop all prescription problems or excuse a missed review deadline.

Recovery of the money or property

Under Rule 111, the civil action to recover civil liability arising from the offense is generally deemed instituted with the criminal case unless the offended party:

Waives the civil action;
Reserves the right to file it separately; or
Filed it before the criminal action.

The correct strategy depends on whether the claim arises from the alleged crime, a contract, or another source of obligation. A separate collection or small-claims case may be more appropriate when the evidence shows only nonpayment or breach of contract rather than criminal fraud.

Repayment or settlement does not automatically erase criminal liability. Once a criminal case is commenced, prosecution is under the direction and control of the public prosecutor. An affidavit of desistance may be considered but does not compel dismissal.

Common mistakes to avoid

Treating every unpaid debt, failed investment, or broken promise as estafa;
Failing to show that deceit existed before or at the time of payment;
Omitting the respondent’s address or facts establishing venue;
Attaching only cropped screenshots instead of complete conversations;
Failing to connect a username or financial account to the respondent;
Hiding partial refunds, settlements, or facts unfavorable to the complaint;
Sending demand letters to the wrong address without preserving proof of service;
Naming a company without identifying the individuals who committed the alleged acts;
Submitting conclusions, hearsay, or speculation instead of firsthand facts;
Posting accusations or personal information publicly, which can create separate legal problems;
Giving away the only copy of original evidence; and
Waiting for informal promises of repayment until evidence disappears or the offense prescribes.

When legal help is urgent

Consult a Philippine criminal lawyer promptly when:

The amount is substantial or several victims are involved;
Checks, falsified documents, land, securities, investments, or corporate transactions are involved;
The respondent is abroad or uses a false identity;
The alleged offender is a public officer or regulated professional;
A cybercrime preservation order, warrant, or forensic examination may be necessary;
You are unsure which city or province has venue;
Barangay conciliation may apply;
The transaction occurred years ago;
You received a dismissal or adverse resolution; or
You are being threatened, pressured to sign a settlement, or asked to surrender original evidence.

For those unable to afford private counsel, ask the Public Attorney’s Office or a recognized legal-aid office whether you qualify for assistance.

Frequently asked questions

Can I file without a lawyer?

Yes. A complainant may execute and file a complaint-affidavit personally. A lawyer is especially helpful when the transaction is complex, the amount is large, venue is disputed, or several possible offenses apply.

Is a police blotter enough?

No. A blotter records a report but ordinarily does not replace the sworn complaint-affidavit, witness affidavits, and evidence required by the prosecution office.

Must I send a demand letter first?

Not in every form of estafa. A demand can nevertheless be important evidence of conversion, non-return, dishonor, notice, or the respondent’s admissions. Check-estafa and BP 22 cases require particularly careful compliance with their distinct notice rules.

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

You can report the incident and seek investigative assistance using every available identifier. Successful prosecution will ordinarily require legally sufficient identification of the responsible person, so early NBI or PNP assistance may be critical.

Will filing recover my money?

Not necessarily. Filing begins an investigation; it does not guarantee conviction, payment, account freezing, or recovery. Report disputed transfers to the financial institutions immediately and discuss civil remedies with counsel.

Can estafa and BP 22 be filed over the same check?

Possibly, because they are distinct offenses, but only if the separate elements of each are supported by the facts. A bounced check issued for a pre-existing debt may fail as estafa even when BP 22 remains a possible issue.

How long do I have to file?

There is no single filing period for every fraud complaint. Prescription depends on the exact offense, prescribed penalty, amount, date of commission or discovery, applicable special law, and events that interrupted the period. The Supreme Court has confirmed that filing the complaint with the prosecution office and beginning the applicable DOJ investigation can interrupt prescription, but an administrative complaint or informal demand is not necessarily equivalent. File promptly and obtain case-specific advice rather than calculating the deadline informally.

What if the respondent offers repayment?

Document the offer and obtain advice before signing a release, compromise, or affidavit of desistance. Repayment may affect the civil claim and the prosecutor’s evaluation, but it does not automatically terminate the criminal case.
