Quick answer

To start an estafa case in the Philippines, 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 any essential part of it—occurred. Attach witness affidavits and evidence showing the specific deceit or abuse of confidence, your reliance or entrustment, the respondent’s acts, and the resulting loss.

You may first report the incident to the police, the National Bureau of Investigation (NBI), or the appropriate cybercrime unit for investigation and evidence-gathering. However, a police blotter or platform report is not necessarily the formal institution of the criminal action. Do not delay filing solely because an investigation, demand, refund discussion, or account-recovery request remains pending.

A failed transaction, unpaid debt, broken promise, or non-delivery does not automatically constitute estafa. The evidence must fit a legally recognized form of fraud under Article 315 of the Revised Penal Code or another applicable law.

When a failed transaction may be estafa

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

Estafa by false pretenses or deceit

The evidence generally must show that:

The respondent made a false representation, used a fictitious name, claimed a qualification, authority, business, property, credit, agency, or transaction that did not exist, or employed a similar deceit.
The deceit occurred before or at the same time you parted with money or property.
You relied on that representation.
Because of that reliance, you suffered damage.

The timing matters. If the false statement arose only after the money had already been delivered, it may not have induced the loss. The Supreme Court has repeatedly required proof that the deceit was the effective reason the victim parted with money or property.

Evidence of deceit may include fabricated documents, false ownership claims, impersonation, invented transactions, contradictory statements, immediate diversion of funds, use of multiple false identities, or proof that performance was impossible or never intended. Mere failure to perform, standing alone, is normally insufficient.

Estafa by misappropriation or conversion

This form may apply when the respondent:

Received money, goods, or other personal property in trust, on commission, for administration, or under an obligation to deliver or return the same property or its proceeds;
Misappropriated or converted it, or denied receiving it;
Acted to another person’s prejudice; and
Had the kind of possession required by law.

The obligation must generally involve returning or delivering the same property or its proceeds—not merely paying an ordinary loan or debt. The Supreme Court has also distinguished juridical possession from an employee’s mere physical custody. For example, an employee who holds company money only on the employer’s behalf may not satisfy this particular element, although a different offense may apply.

A demand is not invariably an element of estafa by misappropriation, but a written demand and proof of receipt can be important circumstantial evidence that the property was not returned or accounted for.

Estafa involving a dishonored check

A bouncing check does not automatically establish estafa. For estafa under Article 315(2)(d), the check generally must have been issued as part of the inducement for the transaction—not merely later as payment for an already existing debt. The law provides a three-day period after receipt of notice of dishonor for purposes of the statutory prima facie evidence of deceit.

A separate case under Batas Pambansa Blg. 22 may be possible even when the check paid a pre-existing obligation. BP 22 has distinct elements, including proper notice of dishonor and an opportunity to pay or arrange full payment within five banking days after receipt of notice. Preserve the original check, bank return slip or dishonor memorandum, written notice, and proof that the drawer actually received the notice. See Batas Pambansa Blg. 22.

Online and technology-assisted fraud

If estafa was committed by, through, or with information and communications technology, Section 6 of the Cybercrime Prevention Act may apply and can increase the prescribed penalty by one degree. But an online conversation alone does not necessarily make the incident “computer-related fraud” under Section 4(b)(2), which specifically concerns unauthorized data input, alteration, deletion, or interference with a computer system.

Online cases may be reported to the PNP or NBI cybercrime units. The DOJ Office of Cybercrime also publishes official reporting guidance. These reports can assist investigation, but the appropriate prosecutor remains responsible for determining the charge and whether the evidence meets the filing standard.

Civil breach versus criminal fraud

The central question is not simply, “Was I paid?” or “Was the promise fulfilled?” It is whether the legally required deceit, conversion, or fraudulent means can be proved.

The case may be primarily civil when the available evidence shows only:

Late or incomplete performance;
Inability to repay a genuine loan;
A business venture that failed despite real efforts;
A contractual disagreement over quality, scope, price, or delivery;
A check issued only after a debt already existed, without evidence that it induced the original transaction; or
A promise that was sincere when made but later became impossible to perform.

A civil claim and a criminal complaint can sometimes arise from the same events, but a criminal complaint should not be used merely to pressure an ordinary debtor. For eligible money claims not exceeding ₱1 million, exclusive of interest and costs, the Small Claims Rules may provide a simpler civil remedy. See the Supreme Court’s Rules on Expedited Procedures.

Where to file

File with the Office of the City or Provincial Prosecutor for the place where the offense was committed or where an essential ingredient occurred. Depending on the evidence, this may be where:

The false representation was made or received;
Money or property was delivered;
Entrusted property was received or converted;
A check was issued or delivered;
The resulting damage occurred; or
Another legally essential act took place.

Estafa can involve acts in several locations. For online transfers, nationwide operations, or transactions involving parties in different cities or provinces, venue can be fact-sensitive. A convenient office is not necessarily the legally proper office. Rule 110 requires the criminal action to be instituted and tried where the offense or an essential ingredient occurred. See the Revised Rules of Criminal Procedure.

Check whether barangay conciliation is required

Katarungang Pambarangay may be a precondition when the parties are natural persons actually residing in the same city or municipality and the dispute falls within the lupon’s authority. Among the exclusions are offenses punishable by imprisonment exceeding one year or a fine exceeding ₱5,000.

Because ordinary estafa involving not more than ₱40,000 carries a maximum imprisonment of six months under Article 315’s general scale, some small-value cases may require barangay proceedings unless another exception applies. Check this before filing and obtain the appropriate certification to file action when required. Urgent exceptions include situations involving detention, provisional remedies, or an approaching prescriptive deadline. See Sections 408–412 of the Local Government Code.

Documents and evidence to prepare

The complaint should present a provable case, not merely a conclusion that the respondent is a “scammer.” Prepare the following where applicable:

Your complaint-affidavit;
Separate sworn affidavits from witnesses with personal knowledge;
Contracts, order forms, invoices, quotations, receipts, acknowledgments, and delivery records;
Bank or e-wallet statements, deposit slips, transfer confirmations, and recipient-account details;
Original checks, dishonor memoranda, notices of dishonor, and proof of receipt;
Complete message or email threads, not only selected screenshots;
Account names, usernames, profile links, telephone numbers, email addresses, websites, advertisements, and listing URLs;
Documents or records disproving the respondent’s claims;
Demand letters, replies, delivery receipts, tracking results, or affidavits of service;
Corporate records showing who made the representation or controlled the transaction;
Witness names, addresses, and contact information;
A transaction-by-transaction computation of the loss; and
A dated chronology connecting each representation, payment, delivery, demand, and response.

For each respondent, state the person’s particular acts. Do not include relatives, shareholders, officers, employees, or directors solely because of their relationship or title. Criminal responsibility ordinarily requires evidence of personal participation, direction, cooperation, or another legally sufficient basis.

Preserve electronic evidence properly

Keep the original device and original electronic records. Do not crop, annotate, overwrite, or delete the only copy. Preserve:

Full conversations with dates and account identifiers;
Original emails and available header information;
Downloaded account or chat archives;
Original files, audio recordings, photographs, and videos;
URLs and the date and time each page was accessed;
Transaction reference numbers;
Platform acknowledgments and support tickets; and
Backups stored separately from the original device.

Ask the bank, e-wallet provider, telecommunications company, marketplace, or platform to preserve relevant records promptly. Some information may later require lawful process or a court warrant; victims should not attempt to hack accounts or obtain protected data unlawfully.

How to write the complaint-affidavit

Use a clear first-person chronology. Include:

Your full name, address, and capacity to complain.
The respondent’s full name and last known address, if known.
The approximate date and place of each material event.
The respondent’s exact representation or the terms under which property was entrusted.
Why the representation was false, or how the entrusted property was converted.
What you did because of the representation or entrustment.
Each amount or item delivered, with supporting records.
When and how you discovered the fraud.
Demands made and the respondent’s response, if relevant.
The specific role of every person charged.
The damage suffered and how it was calculated.
A numbered list of annexes, with each annex referred to in the relevant paragraph.

State facts within your personal knowledge and identify the source of records you did not personally create. Avoid exaggeration, legal conclusions unsupported by facts, or accusations based only on suspicion. False statements in a sworn affidavit can create separate legal consequences.

The affidavit must be subscribed and sworn to before a prosecutor or authorized government officer or, when they are unavailable, a notary public.

Filing requirements

Under the 2024 DOJ–National Prosecution Service rules, prepare:

The original complaint-affidavit;
Two duplicate copies for the official file;
One additional set for each respondent;
The duly accomplished NPS Investigation Data Form;
Witness affidavits; and
All supporting evidence.

Bring extra receiving copies and valid identification. Arrange annexes consistently across every set. Obtain a stamped receiving copy and record the NPS docket number.

Electronic filing and virtual proceedings are recognized as alternatives, but they are not a universal substitute for physical filing. Follow only the official email address, order, and instructions issued by the particular prosecution office. An unapproved email to a publicly listed address may not constitute valid filing.

What happens after filing

The prosecutor first checks whether the complaint is sufficient in form and supported by complete evidence. The applicable procedure depends on the penalty prescribed for the offense—not simply the amount lost.

The DOJ now uses prima facie evidence with reasonable certainty of conviction. The evidence should be admissible, credible, preservable, and capable of proving every element and the identity of the responsible person. The Supreme Court upheld the validity of this DOJ standard in 2026. See the Supreme Court’s official case announcement.

Summary investigation

This generally covers offenses punishable by one day to one year of imprisonment, a fine regardless of amount, or both. It is an ex parte prosecutor’s proceeding: the respondent is not ordinarily required to file a counter-affidavit at this stage. Once the complete record reaches the investigating prosecutor, the case must be resolved immediately.

No motion for reconsideration is allowed under the summary-investigation rules.

Expedited preliminary investigation

This generally covers offenses punishable by one year and one day to six years that fall exclusively within the jurisdiction of a first-level court.

The assisting prosecutor evaluates form and completeness within three calendar days. If case build-up is necessary, the rule gives up to 20 calendar days for it. If a subpoena is needed, it should be issued within five calendar days from receipt of the complete record, and the hearing should be set within 15 calendar days from that receipt. No reply-affidavit or rejoinder is allowed, although a clarificatory hearing may be held when necessary.

After case build-up and docketing, the prosecutor should resolve the case within 20 calendar days from receipt of the entire record. A motion for reconsideration must be filed within 10 calendar days from receipt of the resolution.

Regular preliminary investigation

This covers offenses whose prescribed penalty is at least six years and one day.

Within five calendar days after receiving the complete record, the investigating prosecutor should recommend dismissal or issue a subpoena. The hearing must be set no later than 30 calendar days from receipt of the record. The respondent must receive at least 10 days from receipt of the subpoena and complaint to prepare a counter-affidavit.

A clarificatory hearing may be set within 10 calendar days after receipt of the counter-affidavit. If ordered, a reply or rejoinder must be filed within 10 calendar days from receipt of the pleading being answered.

The investigating prosecutor generally has 60 calendar days from assignment to resolve the complaint. A maximum 30-day extension is permitted for specified circumstances, including complex issues, countercharges, consolidation, and reassignment. A motion for reconsideration must be filed within 15 days from receipt of the resolution.

These are official processing periods, not guarantees that the entire criminal case—including review, court filing, trial, and appeal—will finish within those periods. The governing issuances are DOJ Department Circular No. 15, series of 2024 and Department Circular No. 28, available through the DOJ issuances page.

How the amount affects the case

For most forms of Article 315 estafa, Republic Act No. 10951 uses these general tiers:

Amount of fraud	Prescribed penalty
Not more than ₱40,000	Arresto mayor in its medium and maximum periods
Over ₱40,000 up to ₱1,200,000	Arresto mayor in its maximum period to prisión correccional in its minimum period
Over ₱1,200,000 up to ₱2,400,000	Prisión correccional in its minimum and medium periods
Over ₱2,400,000 up to ₱4,400,000	Prisión correccional in its maximum period to prisión mayor in its minimum period
Over ₱4,400,000	The maximum period of the preceding penalty, with the statutory incremental rule, subject to a 20-year ceiling

Estafa through a bad check under Article 315(2)(d) has a separate and substantially higher penalty scale. Cybercrime Act application may also increase the penalty. These differences can change the investigation track, court jurisdiction, bail consequences, and prescriptive period.

Multiple payments are not automatically added together for penalty purposes. Whether they constitute one offense, several counts, or a continuing scheme depends on the allegations, criminal design, dates, and evidence. See the amended Article 315 in Republic Act No. 10951.

Common mistakes that weaken complaints

Treating every unpaid debt as estafa;
Failing to identify the false representation made before payment;
Submitting screenshots without the complete conversation or account identity;
Omitting proof that money reached an account connected to the respondent;
Naming every officer of a company without describing individual participation;
Filing in a convenient but legally improper venue;
Skipping required barangay conciliation;
Sending a check-demand notice without reliable proof of actual receipt;
Computing the loss without receipts or a transaction schedule;
Waiting for a promised refund until evidence disappears or prescription becomes an issue;
Editing original electronic files;
Publicly accusing people on social media, creating defamation or evidence-preservation problems;
Assuming a police blotter, bank dispute, platform report, or demand letter is already the formal prosecutor’s complaint; or
Ignoring a resolution or subpoena until the short response period has expired.

Recovery of money

A criminal complaint does not freeze an account automatically and does not guarantee repayment. Contact the bank, e-wallet provider, card issuer, or platform immediately to request tracing, recall, preservation, or restriction of the transaction where available. Report unauthorized transactions through the provider’s fraud process and change compromised credentials.

The civil action arising from the offense is generally deemed instituted with the criminal action unless it is waived, reserved, or filed separately under Rule 111. The correct approach depends on whether another civil case already exists, whether provisional relief is needed, and whether the claim arises from the alleged crime or a separate contract. Avoid duplicate recovery or inconsistent cases.

Payment, settlement, or an affidavit of desistance does not automatically terminate estafa, which is prosecuted in the name of the People of the Philippines. The prosecutor and court determine its legal effect.

Do not wait for the prescriptive period

Prescription depends on the precise offense, its prescribed penalty, the date of commission or discovery, and acts that legally interrupt the period. Under Articles 90 and 91 of the Revised Penal Code, different classifications can carry periods of five, ten, fifteen, or twenty years. Estafa is generally reckoned from actual or reasonably discoverable knowledge of the crime, but a complainant cannot indefinitely postpone prescription by delaying a demand after the fraud was already apparent.

A barangay complaint interrupts prescription only within the limits stated in the Local Government Code. A private demand, police inquiry, bank complaint, or platform ticket should not be assumed to interrupt it. Obtain legal advice immediately if the events occurred years ago. See Articles 90 and 91 of the Revised Penal Code.

When legal help is urgent

Consult a Philippine criminal-law lawyer or the Public Attorney’s Office promptly when:

The possible prescriptive period is close;
The amount is substantial or involves many victims;
Funds may still be frozen, traced, or recalled;
The respondent used several identities, companies, accounts, or jurisdictions;
The case involves cryptocurrency, foreign platforms, or an overseas respondent;
You need subpoenas or preservation of records held by third parties;
A corporation, public officer, securities offering, trust receipt, falsified document, or public funds are involved;
There are threats, coercion, stalking, or danger to a victim or witness;
A child or person unable to execute an affidavit independently is involved;
The prosecutor dismisses the complaint;
You receive a subpoena, resolution, or court notice; or
You are considering several simultaneous criminal and civil remedies.

Remedy periods can be short. Regular preliminary-investigation resolutions generally allow a motion for reconsideration within 15 days, while expedited cases allow only 10 calendar days and summary-investigation cases do not allow one under the 2024 rules.

Frequently asked questions

Can I file an estafa complaint without a lawyer?

Yes. A lawyer is not legally required merely to submit a complaint-affidavit. Counsel is valuable when venue, the correct offense, electronic evidence, multiple respondents, prescription, or parallel civil remedies are disputed.

Should I go to the police, NBI, or prosecutor first?

You may report to the police or NBI when investigation, identification, record preservation, or cybercrime assistance is needed. You may also file a sufficiently supported complaint directly with the proper prosecution office. For a recent warrantless arrest, the law-enforcement agency ordinarily refers the matter for inquest.

Can I file against an unknown online scammer?

You can report the incident and submit the identifiers you have, such as account numbers, usernames, phone numbers, URLs, transaction references, and delivery information. The formal charge ultimately requires sufficient evidence identifying the responsible person. Platforms and financial institutions may disclose protected records only through appropriate legal process.

Does a demand letter have to be sent before filing?

Not in every estafa case. A demand can nevertheless help prove non-return, conversion, notice, or the respondent’s response. Dishonored-check cases have special notice requirements, so proof of actual receipt is especially important.

Will the respondent be arrested as soon as I file?

No. Filing a complaint-affidavit does not itself create an arrest warrant. The prosecutor first determines whether to file an information. The court then independently evaluates probable cause for a warrant or summons, as applicable. A lawful warrantless arrest follows separate inquest rules.

Can the case continue if the respondent refunds the money?

Possibly. Refund or settlement may affect the civil claim and the parties’ evidence, but it does not automatically erase a completed public offense or compel dismissal. Do not sign a quitclaim, compromise, or affidavit of desistance without understanding its consequences.
