Quick answer

To start an estafa case, file a sworn complaint-affidavit, witness affidavits, 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. Complete the National Prosecution Service Investigation Data Form and bring the required copies.

You may first seek investigative assistance from the police or the National Bureau of Investigation (NBI), especially when the offender’s identity is uncertain, several victims are involved, or digital evidence must be preserved. But a police blotter or report is not necessarily the complaint filed with the prosecutor. Keep proof that the prosecutor’s office formally received and docketed your complaint.

The prosecutor will not treat every unpaid debt, failed investment, broken promise, or breach of contract as estafa. Your evidence must establish the particular form of fraud defined by law, identify the responsible person, and show how the deception or misuse of entrusted property caused your loss.

When fraud amounts to estafa

Estafa is principally punished under Article 315 of the Revised Penal Code, as amended by Republic Act No. 10951. Common forms include the following.

Estafa through false pretenses

This generally requires proof that:

The respondent made a false representation, used a fictitious identity, claimed qualifications, authority, property, credit, business, or a transaction that did not exist, or employed a similar deceit;
The deceit occurred before or at the same time the victim parted with money or property;
The victim relied on it; and
The reliance caused financial or property damage.

The Supreme Court applied these elements in Palaoag v. People. Deceit that arose only after the money was delivered ordinarily does not satisfy this form of estafa. Read the decision.

Estafa through misappropriation or conversion

This may arise when a person receives money, goods, or other personal property:

In trust;
On commission;
For administration; or
Under an obligation requiring delivery or return,

and then misappropriates or converts it, denies receiving it, and causes prejudice to another.

The transaction must transfer not merely physical custody but the kind of juridical possession contemplated by Article 315(1)(b). A demand is useful evidence of misappropriation but is not indispensable when conversion is clearly established by other evidence. The Supreme Court discussed these distinctions in Buenaflor v. Office of the Secretary of Justice. Read the decision.

An unpaid debt is not automatically estafa

Nonpayment alone ordinarily creates a civil—not criminal—claim. The documents and actual arrangement matter. For example:

A borrower’s later inability to repay does not by itself prove that the loan was obtained through deceit.
A buyer’s failure to pay the balance of a genuine sale is not automatically misappropriation of property held in trust.
A business that failed despite genuine operations is different from a nonexistent venture used from the beginning to obtain money.
A promise that was honestly intended when made does not necessarily become criminal merely because it was later broken.

A criminal complaint should identify the deceit existing at the time of the transaction or the specific trust obligation and later conversion. Criminal proceedings must not be used solely to pressure someone into paying an ordinary debt.

Where to file

Office of the prosecutor

File with the Office of the City Prosecutor or Office of the Provincial Prosecutor for the locality where the offense was committed or where an essential ingredient occurred. Venue is not automatically determined by the complainant’s home, the respondent’s home, or the location of the respondent’s bank.

Fraud transactions may involve several places: where a false statement was made or received, where money was delivered, where entrusted property should have been returned, or where the resulting damage occurred. Online cases have additional jurisdiction rules. If venue is uncertain, ask the relevant prosecution offices to confirm jurisdiction before filing or consult counsel. Rule 110 generally requires prosecution where the offense or an essential ingredient occurred. See the Rules of Criminal Procedure.

Police or NBI assistance

A complainant may approach law enforcement before or alongside preparation of the prosecutor complaint when investigation is needed.

For conventional fraud, the NBI accepts requests for investigative assistance through its Complaints and Recording Division and appropriate investigation units.
For an internet scam, compromised account, identity misuse, or other cyber-related incident, approach the NBI Cybercrime Division or the Philippine National Police Anti-Cybercrime Group.
The NBI also provides an online complaint page and publishes its fraud and cybercrime assistance procedures.

Law-enforcement investigation can help identify account holders, obtain records through lawful process, and preserve computer data. It does not guarantee recovery or prosecution.

Act immediately after discovering the fraud

Contact the bank, e-wallet, card issuer, or payment provider. Report the transaction as fraudulent and obtain a case or reference number. Ask what documents are required for tracing, recall, restriction, or preservation. A reversal or freeze is not guaranteed.
Secure your accounts. Change compromised passwords, revoke unknown sessions, enable multi-factor authentication, and notify your mobile provider if SIM takeover is suspected.
Preserve the original evidence. Do not delete chats, reset the device, surrender the only copy of a document, or edit the original files.
Report the account or listing to the platform. Save the report confirmation before content or profiles disappear.
Seek cybercrime assistance quickly. Under Republic Act No. 10175, service providers preserve certain traffic data and subscriber information for specified periods, while preservation of content data may require a law-enforcement order. Delay can make identification and evidence recovery harder. See the Cybercrime Prevention Act.
Prepare a dated chronology. Record each representation, payment, delivery, demand, response, and discovery of the fraud.

Evidence to preserve

Collect evidence establishing every step from the representation or entrustment to the resulting loss.

Identity and contact information

Full name and aliases;
Known home, business, or service address;
Telephone numbers and email addresses;
Social-media usernames and profile links;
Bank or e-wallet account details;
Government-issued identification shown during the transaction;
Company name, registration details, position, and proof identifying the person who acted.

Do not publicly post private identifying information or threaten the suspected offender. Give it to investigators and prosecutors.

Transaction records

Contracts, purchase orders, invoices, receipts, acknowledgment receipts, promissory notes, and delivery records;
Bank statements, deposit slips, transfer confirmations, card records, and e-wallet transaction details;
Check images, bank return slips, and notices of dishonor;
Proof of the amount and date of each payment;
Accounting records showing property received, amounts returned, and the outstanding loss.

Communications and digital evidence

Complete chat or email threads, not only selected screenshots;
Original electronic files and downloaded account data;
Screenshots showing the username, date, time, URL, and surrounding context;
Advertisements, listings, websites, proposals, presentations, and voice messages;
Call logs and lawful recordings;
Platform-report confirmations and bank or e-wallet complaint numbers.

Keep an untouched copy. Cropping or annotating a duplicate for explanation is acceptable, but retain the original. Do not access the respondent’s account without permission, impersonate another person, or obtain evidence by hacking.

Witness and demand evidence

Names and contact details of witnesses with personal knowledge;
Separate sworn affidavits describing what each witness personally saw or heard;
Demand letters and proof of actual delivery or receipt;
Replies, promises to repay, admissions, or attempts to conceal the transaction.

A demand letter is not universally required for estafa, but it can help establish refusal to account for or return entrusted property. It is especially important in bouncing-check cases, where the applicable statutes create specific notice and payment periods.

How to prepare the complaint-affidavit

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

Your full name, address, and contact information;
The respondent’s name, address, and identifying details, as far as known;
The parties’ relationship and how contact began;
The exact false statements, acts, documents, or trust arrangement involved;
When, where, and how each statement or act occurred;
Why you relied on it;
Each payment or item delivered, including dates and reference numbers;
How and when you discovered the fraud;
Any demand, response, admission, concealment, or refusal;
The precise amount or property lost;
The participation of each respondent, without assuming that every companion, employee, or officer was part of the scheme; and
A list of annexes and witnesses.

Attach documents in a logical sequence and label them consistently. Explain what each annex proves. Avoid conclusions such as “the respondent is obviously a scammer” without supporting facts.

The affidavit must be subscribed and sworn to before a prosecutor, another government official authorized to administer oaths, or, when permitted, a notary public. False statements under oath may create separate liability.

Filing requirements

Under the current DOJ-NPS framework, prepare at least:

The original complaint-affidavit;
Two duplicate copies for the official file;
One complete copy for every respondent;
A completed NPS Investigation Data Form;
Witness affidavits;
All supporting documentary, electronic, and object evidence;
Proof of the complainant’s authority if filing for a corporation or another person; and
A barangay certificate to file action when barangay conciliation is legally required.

The receiving office may prescribe document arrangement, paper size, electronic media, or additional administrative requirements. Confirm its current checklist before submission. Obtain a stamped receiving copy showing the date, office, and docket or reference number.

Is barangay conciliation required?

Possibly, but only within the statutory coverage of the Katarungang Pambarangay system.

Conciliation is generally a prerequisite when the dispute is between individuals actually residing in the same city or municipality and no exception applies. The lupon does not have authority over, among others, offenses punishable by imprisonment exceeding one year or a fine exceeding ₱5,000, cases involving the government in specified circumstances, and disputes between residents of different cities or municipalities unless the adjoining-barangay exception and agreement apply.

This issue most often arises in lower-value, non-cyber estafa complaints whose prescribed imprisonment does not exceed one year. Online commission, a different estafa mode, or another accompanying offense may change the penalty and the result. If conciliation applies, obtain the proper certification before going to the prosecutor. Barangay proceedings interrupt prescription only within the limits stated in Section 410 of the Local Government Code. See Sections 408–412 of Republic Act No. 7160.

What happens after filing

Current DOJ rules require prima facie evidence with reasonable certainty of conviction. The evidence must be credible, admissible, capable of preservation and presentation, and sufficient to establish the elements of the offense and the responsible person’s identity. The Supreme Court upheld this prosecutorial framework in Meking v. Remulla. Read the decision.

The procedure depends on the prescribed penalty and court jurisdiction.

DOJ track	General coverage	Key procedure
Summary investigation	Offenses punishable by one day to one year, a fine regardless of amount, or both	Generally resolved ex parte from the complaint and evidence. No motion for reconsideration is allowed under this track.
Expedited preliminary investigation	Offenses punishable by one year and one day to six years and exclusively within first-level court jurisdiction	The assisting prosecutor evaluates the filing within three calendar days. Case build-up, when required, must generally be completed within 20 calendar days. If a subpoena is issued, the hearing must be set within 15 calendar days from receipt of the complete record. No reply or rejoinder is ordinarily allowed. A motion for reconsideration may be filed within 10 calendar days from receipt of the resolution.
Regular preliminary investigation	Generally, offenses punishable by at least six years and one day and cases placed within RTC jurisdiction by law	The investigating prosecutor initially reviews the complete record, may issue a subpoena, and must give the respondent at least 10 calendar days to submit a counter-affidavit. The ordinary overall resolution period is 60 calendar days, extendible by 30 days for complex cases or capital offenses. A motion for reconsideration must generally be filed within 15 calendar days from receipt.

These periods come from DOJ Department Circular No. 015, series of 2024 and DOJ Department Circular No. 028, series of 2024. The office determines the proper track from the charge, prescribed penalty, amount, and jurisdiction—not merely from the label written by the complainant.

If the required standard is met, the prosecutor files an Information in court. The judge then independently determines judicial probable cause, including whether a warrant or summons should issue. Filing a complaint does not itself mean that the respondent is guilty or will immediately be arrested.

Penalties and amount thresholds

For the ordinary forms of estafa under Article 315—excluding the special penalty schedule for estafa by postdated or unfunded check—the prescribed penalties depend on the amount:

Amount of fraud	Prescribed penalty
Not more than ₱40,000	Arresto mayor in its medium and maximum periods
More than ₱40,000 but not more than ₱1,200,000	Arresto mayor maximum to prisión correccional minimum
More than ₱1,200,000 but not more than ₱2,400,000	Prisión correccional minimum and medium
More than ₱2,400,000 but not more than ₱4,400,000	Prisión correccional maximum to prisión mayor minimum
More than ₱4,400,000	The maximum period applies, with an additional year for every additional ₱2,000,000, subject to the statutory 20-year ceiling

The court’s actual sentence depends on the proven offense, amount, modifying circumstances, applicable penalty rules, and the Indeterminate Sentence Law. See Section 85 of Republic Act No. 10951.

Special rules for dishonored checks

A bounced check may involve:

Estafa under Article 315(2)(d);
A violation of Batas Pambansa Blg. 22;
Both, if the separate elements of each offense are established; or
Only civil liability, if the criminal elements cannot be proven.

For estafa by check, the check must generally have been part of the deceit that induced the victim to part with money or property. A check issued only to pay an already-existing obligation ordinarily cannot have induced the earlier delivery. Article 315(2)(d) also provides a three-day period from receipt of notice of dishonor for purposes of its statutory prima facie evidence of deceit.

BP 22 is a separate offense. When the check was presented within 90 days from its date, failure to pay or arrange full payment within five banking days after receipt of notice of dishonor may create prima facie evidence of knowledge of insufficient funds. Preserve:

The original check;
The bank’s return slip or stamped reason for dishonor;
Written notice of dishonor;
Proof that the drawer actually received the notice; and
Proof that the applicable payment period expired.

Estafa by check carries a separate, substantially higher penalty schedule under Article 315. Do not apply the ordinary estafa table to it. See Article 315 as amended and Batas Pambansa Blg. 22.

Online scams and cyber-enabled estafa

When estafa is committed by, through, or with information and communications technology, Section 6 of Republic Act No. 10175 may apply and increase the penalty by one degree. Cybercrime cases fall within RTC jurisdiction under that law. These provisions can affect venue, the investigation track, penalty, and prescription.

An online transaction is not automatically “computer-related fraud” under Section 4(b)(2). That separate offense concerns unauthorized input, alteration, or deletion of computer data or interference with a computer system, done with fraudulent intent and causing damage. An ordinary lie delivered through chat may instead be prosecuted as estafa in relation to Section 6, depending on the evidence and charging decision.

Promptly report cyber-enabled fraud to a specialized unit so lawful preservation and disclosure processes can begin. The PNP Anti-Cybercrime Group’s reporting guidelines explain the handling of cybercrime and cyber-related incident reports.

Prescription: do not wait

The deadline for prosecuting estafa is not a single fixed number. Under Articles 90 and 91 of the Revised Penal Code, it depends on the prescribed penalty and therefore on the form of estafa, amount, and any applicable special law. Depending on those factors, the period may be five, 10, 15, or 20 years.

For Revised Penal Code offenses, the period generally runs from discovery of the crime by the offended party, authorities, or their agents—not from a demand letter deliberately sent years later when the fraud was already known. Online or special-law charges may require a different computation.

The Supreme Court has clarified prospectively that filing the requisite complaint with the DOJ and beginning the applicable investigation interrupts the prescriptive period, including for offenses subject to summary investigation. See the Supreme Court’s official guidance.

Do not rely on an informal report, platform complaint, demand letter, or police blotter alone to stop prescription. If the transaction is old, the limitation period is close, or the date of discovery is disputed, consult a lawyer immediately and file through the legally appropriate channel.

Recovering the money or property

When a criminal action is instituted, the civil action to recover civil liability arising from the offense is generally deemed included unless the offended party:

Waives it;
Properly reserves the right to file it separately; or
Filed the civil action before the criminal case.

Actual loss should therefore be alleged and documented. A separate civil case may sometimes be more appropriate when the evidence proves a debt or contractual breach but not criminal deceit. The choice affects filing fees, prescription, possible suspension of proceedings, and recovery strategy. Double recovery for the same injury is not allowed. See Rule 111.

Common mistakes

Treating nonpayment alone as proof of estafa;
Failing to identify the particular false statement, trust obligation, or act of conversion;
Filing where the parties live without checking where an essential element occurred;
Naming corporate officers merely because of their titles, without evidence of personal participation;
Submitting cropped screenshots while losing the original conversation;
Providing only a payment confirmation without proof of the representation that caused the payment;
Waiting too long to seek preservation of platform, subscriber, or banking records;
Sending a demand to the wrong address and claiming it was received;
Ignoring a possible barangay-conciliation prerequisite;
Filing the wrong number of copies or an unsworn narrative;
Exaggerating the loss, concealing refunds, or including facts outside personal knowledge;
Assuming a police report automatically becomes a prosecutor complaint; and
Posting accusations publicly, which may create privacy, defamation, or evidence problems.

When legal help is urgent

Consult a Philippine lawyer without delay when:

Prescription may be close;
The amount is substantial or there are numerous victims;
The offender’s identity is unknown or records may soon disappear;
Funds are still moving through banks, e-wallets, cryptocurrency services, or overseas accounts;
The respondent or evidence is outside the Philippines;
Several cities or provinces may claim venue;
The transaction involves a corporation, securities solicitation, regulated investment, public officer, or government funds;
A bounced-check complaint may involve both estafa and BP 22;
You already filed a civil case or signed a settlement, waiver, release, or quitclaim;
The prosecutor dismissed the complaint; or
You received a resolution or court notice carrying a 10- or 15-calendar-day remedy period.

Qualified complainants may inquire with the Public Attorney’s Office about available legal assistance. Law enforcement can investigate, but it does not replace advice on venue, charges, civil recovery, and prosecutor remedies.

Frequently asked questions

Do I need a lawyer to file?

A complainant may prepare and file a complaint-affidavit without private counsel. Legal assistance is strongly advisable when the facts are complex, several offenses may apply, venue is uncertain, or significant money is involved.

Must I send a demand letter first?

Not in every estafa case. Demand can be important evidence of refusal, conversion, or notice, but it is not universally an element. Dishonored-check cases have specific notice rules that should be followed carefully.

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

You may seek police or NBI assistance and provide every available identifier. Whether a prosecutorial complaint can proceed against an unidentified respondent depends on the evidence and the ability of lawful investigation to identify the responsible person.

Can the respondent be arrested immediately after I file?

Normally, filing initiates prosecutorial screening or investigation. If an Information is later filed, the judge independently determines probable cause and whether a warrant or summons is appropriate. Warrantless arrest is allowed only in the limited situations provided by law.

What if the prosecutor dismisses the complaint?

The available remedy depends on whether the case underwent summary, expedited, or regular investigation. Summary-investigation resolutions do not allow a motion for reconsideration under DOJ Circular No. 028; expedited cases allow one within 10 calendar days; regular preliminary-investigation cases generally allow one within 15 calendar days. Obtain counsel immediately because further review routes and requirements depend on the court that would have jurisdiction.

Will filing guarantee that I recover my money?

No. Investigation, prosecution, conviction, and collection are separate issues. Recovery depends on the evidence, available assets, civil liability, defenses, and enforcement of any judgment or settlement.

Can several victims file together?

They may coordinate with law enforcement and counsel, but each transaction and each victim’s reliance, payment, and loss must be supported by evidence. Whether claims should be consolidated or separately charged is a prosecutorial determination.
