Quick answer

To start an estafa case, file a sworn complaint-affidavit, witness affidavits, and supporting evidence with the City or Provincial Prosecutor’s Office that has territorial venue over the offense. The prosecutor—not the complainant—decides whether the evidence supports estafa or another offense and, if it does, files the Information in court.

You may first seek investigative assistance from the police or the National Bureau of Investigation (NBI), particularly when the offender used a fake identity, the transaction was online, financial records must be traced, or digital forensics is needed. A police blotter, platform report, or bank complaint is useful evidence, but ordinarily is not a substitute for the sworn complaint filed with the prosecution office.

If money was recently transferred through a bank or e-wallet, report the disputed transaction to the financial institution immediately. Under the Anti-Financial Account Scamming Act and BSP rules, funds meeting the applicable criteria may be temporarily held for up to 30 calendar days while the transaction is verified. A hold is not automatic and does not guarantee recovery.

Check whether the facts amount to estafa

“Fraud” is a broad description. Estafa is a specific crime under Article 315 of the Revised Penal Code, as amended by Republic Act No. 10951. The evidence must fit a legally recognized mode of estafa.

Estafa through false pretenses or fraudulent representations

This commonly applies to fake investments, fictitious businesses, false claims of ownership or authority, impersonation, and similar schemes. The evidence should show that:

The respondent made a material false representation or used a fraudulent means.
The deception existed before or at the time the victim parted with money or property.
The victim relied on it.
The victim suffered actual damage.

The Supreme Court applies these elements strictly. A lie discovered only after payment is not enough unless the evidence shows that the deception already existed when the money or property was obtained. See, for example, the Court’s discussion in Rivera v. People.

Estafa through misappropriation or conversion

This may apply when the respondent received money or personal property in trust, on commission, for administration, or under an obligation to deliver or return it, but instead treated it as their own or denied receiving it.

The complainant must establish the nature of the original delivery. A loan, ordinary debt, or employer’s transfer of mere physical custody may not create the juridical possession required for this form of estafa. The exact contract and the parties’ relationship matter.

A written demand is often useful evidence of non-return or misappropriation, but the Supreme Court has clarified that demand is not invariably an essential element of estafa through abuse of confidence. Do not postpone filing solely to send repeated demands if evidence may disappear or prescription is approaching. See G.R. No. 277067, May 7, 2025.

Estafa involving a dishonored check

A dishonored check does not automatically establish estafa. For estafa under Article 315(2)(d), the check ordinarily must have been used to induce the victim to part with money or property when the obligation was contracted. A check issued only to pay a pre-existing debt generally does not supply that inducement.

Article 315(2)(d) contains a three-day rule relating to the statutory presumption of deceit after receipt of notice of dishonor. A separate prosecution under the Bouncing Checks Law, B.P. Blg. 22, has different elements, including written notice of dishonor and a five-banking-day opportunity to pay or arrange full payment. Preserve the original check, bank return slip, written notice, and proof that the drawer actually received the notice.

A broken promise or unpaid debt is not automatically estafa

Failure to repay a loan, deliver an item, complete a project, or perform a contract may create civil liability without criminal estafa. For estafa by deceit, the prosecution must prove fraudulent intent and a false representation existing before or simultaneously with the victim’s payment. A later inability or refusal to perform, standing alone, does not prove that initial deceit.

Depending on the evidence, the proper remedy may instead be collection, rescission, damages, a consumer or regulatory complaint, B.P. Blg. 22, computer-related fraud, or another criminal offense. State the facts accurately and allow the prosecutor to determine the correct charge.

Act immediately to limit further loss

If the transaction is recent:

Contact the sending bank, e-wallet, card issuer, or payment provider through its official fraud channel. Ask it to flag the transaction, trace the receiving account, begin coordinated verification, and preserve relevant records. Obtain a reference number.
Notify any receiving institution if its verified official channel accepts reports from sending account owners.
Change compromised passwords from a clean device, revoke unknown sessions, and enable stronger authentication.
Report the account, advertisement, profile, or listing to the platform, but preserve it before it is removed.
Do not pay a “recovery agent,” “investigator,” or alleged government employee who promises a guaranteed refund.
Do not confront, threaten, publicly dox, or attempt your own entrapment of the suspected offender.

The Anti-Financial Account Scamming Act and BSP Circular No. 1215 govern the temporary holding and coordinated verification of disputed electronic fund transfers. If the institution does not satisfactorily address a consumer complaint, the BSP instructs consumers to use the institution’s own assistance mechanism first and then escalate through the BSP Consumer Assistance Mechanism.

Evidence to preserve

Build the case around admissible proof of every element, not merely a conclusion that the respondent is a “scammer.”

Identity and contact information

Preserve every available identifier:

Full name, aliases, usernames, profile IDs, email addresses, telephone numbers, and physical addresses
Bank or e-wallet account name and masked account details
Business name, registration details, receipts, invoices, and identification shown to you
Photographs, voice recordings, video-call details, delivery records, vehicle details, and witnesses who met the respondent
Links to profiles, posts, advertisements, websites, and marketplace listings

Do not assume that the registered account owner personally devised the fraud. Explain what connects each proposed respondent to the representations, receipt of funds, or disposition of property.

Proof of the deception or trust arrangement

Keep:

The original advertisement, proposal, investment presentation, quotation, contract, purchase order, acknowledgment receipt, trust receipt, agency document, or commission agreement
Complete chat threads, emails with headers, text messages, call logs, and voice messages
Documents allegedly showing ownership, authority, qualifications, licenses, inventory, projects, or expected returns
Evidence showing that the representation was false when made, such as official certifications, registry records, responses from the real company, or statements from persons who were impersonated
For entrusted property, the document showing why it had to be returned, delivered, accounted for, or used only for a stated purpose

Proof of reliance, transfer, and damage

Preserve:

Deposit slips, transfer confirmations, bank statements, card records, remittance receipts, and transaction reference numbers
Proof that the respondent or a person acting with them instructed you where to send the money
Delivery receipts, inventory records, serial numbers, and valuations of property
A transaction table showing the date, amount, recipient account, stated purpose, and supporting annex for every payment
Refunds or partial repayments, accurately deducted from the claimed loss
Expenses or other damages being claimed, supported by receipts and a clear explanation of causation

Digital evidence

Keep the original device and original files whenever possible. Export full conversations and emails instead of relying only on selected screenshots. Save visible dates, times, usernames, URLs, transaction references, and surrounding context. Do not crop, annotate, overwrite, or edit the only copy.

Electronic documents are admissible only when the applicable evidentiary and authentication requirements are met. The person offering them bears the burden of showing their integrity and reliability under the Supreme Court’s Rules on Electronic Evidence.

Maintain at least two secure backups. Record when, where, and how each file was obtained. If a device may contain malware or important forensic data, seek assistance before resetting or reformatting it.

Where to file

The proper prosecution office

File with the City or Provincial Prosecutor’s Office covering the place where the crime was committed or where an essential element occurred. Under Rule 110, criminal venue is jurisdictional.

Relevant places may include where:

The fraudulent representation was made or received
The victim relied on it and released money or property
Entrusted property was received, converted, or required to be returned
The check was issued or delivered
The legally relevant damage occurred

Online transactions involving people and accounts in different locations require careful venue analysis. Your residence alone does not necessarily establish venue. State every relevant location in the affidavit and confirm the receiving office before filing. The DOJ lists NCR and regional, city, and provincial prosecution offices.

Police or NBI investigation

Seek law-enforcement assistance when the offender is unidentified, records must be obtained from third parties, several victims or jurisdictions are involved, or digital examination is needed.

The NBI offers:

An initial online or investigative report may still require personal appearance, sworn statements, production of devices, or a later complaint before the prosecutor. Keep every referral, acknowledgment, and case number.

Possible barangay conciliation

Barangay conciliation may be a precondition in a limited, lower-penalty dispute between individuals who actually reside in the same city or municipality. It generally does not apply when the offense is punishable by imprisonment exceeding one year or a fine exceeding ₱5,000, when a corporation or other juridical entity is a party, or when another statutory exception applies.

Because ordinary estafa penalties depend on the amount and mode, a lower-value case may require a Certificate to File Action while a more serious case may be exempt. Ask the prosecution office or a lawyer before bypassing the barangay process. The governing provisions are Sections 408 and 412 of the Local Government Code.

How to prepare and file the complaint

1. Write a chronological complaint-affidavit

The affidavit should contain:

Your full name, address, and capacity to complain
Each respondent’s known name and address, plus aliases and identifiers
The approximate dates and exact places material to venue
The precise statements, documents, or acts that were false
Why those representations were false when made
How you relied on them
Every payment or delivery of property
What happened afterward
The amount of actual loss, less any recovery
The specific act of each respondent
A numbered list of witnesses and annexes

Quote only material portions of communications, then attach the complete conversation where practicable. Avoid exaggeration, unsupported conclusions, hearsay presented as personal knowledge, and claims that conflict with the documents.

If the complainant is a corporation, partnership, association, or estate, attach proper proof that the affiant is authorized to act and that the documents are authentic business records. Criminal allegations should identify the natural persons whose own acts or participation are supported by evidence; naming a company alone may be insufficient.

2. Attach witness affidavits and organized annexes

Each witness should ordinarily execute a separate sworn affidavit limited to facts personally known to that witness. Mark annexes consistently and refer to each one in the relevant paragraph.

A useful arrangement is:

Identity and authority documents
Contract or transaction documents
Deceptive representations
Payment or delivery records
Subsequent communications and demands
Bank, platform, police, or agency reports
Proof of loss
Witness affidavits
Digital-evidence index

Bring originals for comparison and preserve them after filing unless they are formally received as evidence.

3. Prepare the required copies and data form

Under the DOJ’s 2024 rules, the filing package generally consists of:

The original complaint-affidavit
Two duplicate copies for the official file
One additional complete copy for each respondent
The affidavits of witnesses
All supporting evidence
A duly accomplished NPS Investigation Data Form

The complaint must state the parties’ names and addresses, the date and place of the alleged offense, and the facts showing how it was committed. Confirm the office’s current administrative checklist before filing. Electronic filing and virtual proceedings are alternatives under the rules, but use them only through an official address or specific instruction from the prosecution office.

4. Sign under oath and file

The complaint must be sworn before an official authorized to administer oaths or a notary public, as applicable. Do not sign a jurat falsely or claim personal knowledge of matters you learned only from others.

At filing:

Obtain a stamped receiving copy.
Record the docket or NPS case number.
Note the date, office, receiving personnel, and documents submitted.
Keep proof of any electronic transmission and service.
Update your contact details if they change.
Attend every scheduled hearing and respond only through the authorized channels.

What happens after filing

The prosecution office first evaluates whether the complaint is sufficient in form and whether the evidence is complete. It may require further case build-up. The applicable procedure depends on the offense’s prescribed penalty and the court that would have jurisdiction:

Procedure	General coverage under the 2024 DOJ rules	Important remedy after an adverse resolution
Summary investigation	Offenses generally punishable by one day to one year, a fine, or both	No motion for reconsideration under DOJ Circular No. 28
Expedited preliminary investigation	Offenses generally punishable by one year and one day to six years and exclusively within first-level court jurisdiction	Motion for reconsideration within 10 calendar days
Regular preliminary investigation	Offenses punishable by at least six years and one day, and cases otherwise cognizable by the Regional Trial Court	Motion for reconsideration within 15 days from receipt

This classification cannot safely be determined from the amount alone. Check-related estafa has a separate penalty scale, an offense committed through information and communications technology may carry a penalty one degree higher under Section 6 of the Cybercrime Prevention Act, and special laws may apply.

In a regular preliminary investigation, the respondent ordinarily receives the complaint and evidence and is directed to submit a counter-affidavit. The complainant may be allowed or directed to file a reply when new and substantial matters require one. In an expedited investigation, reply and rejoinder affidavits are generally not entertained, although the prosecutor may hold a clarificatory hearing. A summary investigation may be resolved from the complainant’s evidence without the full exchange used in regular proceedings.

The current DOJ standard is 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 the identity of the responsible person. The Supreme Court upheld the DOJ’s authority to apply these rules in Meking v. Remulla, G.R. No. 280455, November 11, 2025.

If the prosecutor approves the filing of an Information, the case proceeds to court. Filing the complaint does not itself produce a warrant of arrest. The judge independently determines whether judicial probable cause exists and whether a warrant or summons is appropriate.

Why the amount matters

For common forms of estafa other than the special check-related penalty scale, Article 315 currently provides these base ranges:

Amount of fraud	Base statutory penalty
Not over ₱40,000	Arresto mayor, medium to maximum
Over ₱40,000 but not over ₱1,200,000	Arresto mayor, maximum, to prisión correccional, minimum
Over ₱1,200,000 but not over ₱2,400,000	Prisión correccional, minimum to medium
Over ₱2,400,000 but not over ₱4,400,000	Prisión correccional, maximum, to prisión mayor, minimum
Over ₱4,400,000	The statutory maximum-period and incremental rules apply, subject to the 20-year cap stated in Article 315

The amount, mode of estafa, date of commission, aggravating or mitigating circumstances, use of technology, and applicable special law can alter the charge, procedure, court jurisdiction, penalty, and prescriptive period. Syndicated or large-scale schemes may also require evaluation under Presidential Decree No. 1689.

Do not wait for the prescriptive period

Articles 90 and 91 of the Revised Penal Code provide different prescriptive periods according to the penalty: five years for offenses punishable by arresto mayor, ten years for correctional penalties generally, fifteen years for other afflictive penalties, and twenty years for offenses punishable by reclusion temporal or the higher penalties listed in Article 90.

For estafa, prescription generally runs from discovery of the crime by the offended party, authorities, or their agents—not from a later demand chosen by the complainant. The exact discovery date can be disputed, particularly when earlier facts should reasonably have revealed the loss or conversion.

The Supreme Court has prospectively clarified that filing the criminal complaint with the prosecution office interrupts prescription even for cases governed by expedited procedures. See Consebido v. People, G.R. No. 258563, April 2, 2025. Nevertheless, do not calculate the last filing day without legal advice or delay until the apparent deadline.

Common mistakes that weaken complaints

Treating nonpayment or poor contract performance as proof of initial criminal deceit
Attaching only payment receipts without proving what false representation induced the payment
Omitting the respondent’s address or the places necessary to establish venue
Naming every officer or employee of a company without evidence of personal participation
Submitting cropped screenshots without the complete conversation, account identifier, URL, or date
Editing, resetting, selling, or losing the device containing the original evidence
Claiming the gross amount transferred while concealing refunds or partial performance
Combining unrelated transactions without explaining how they form one scheme
Filing inconsistent versions with the bank, police, NBI, barangay, and prosecutor
Assuming a police blotter or online report already instituted the prosecutor’s case
Sending a check demand without preserving proof of actual receipt
Missing a subpoena, hearing, reply deadline, or short reconsideration period
Publishing accusations online in a way that creates separate privacy, harassment, or defamation issues

When legal help is urgent

Consult a Philippine criminal-law practitioner promptly when:

The transfer is recent and funds may still be traceable
The respondent’s identity or location is unknown
Several bank, e-wallet, cryptocurrency, or foreign accounts were used
There are many victims, corporate respondents, or suspected conspirators
The case involves an investment, securities offering, recruitment scheme, trust receipt, real property, or dishonored checks
The respondent is a public officer and the alleged act concerns official duties
The respondent or evidence is abroad
A prosecutor has dismissed the complaint
You received a subpoena, counter-affidavit, or adverse resolution
Prescription may be near
There are threats, ongoing account compromise, evidence deletion, or risk of further loss

A lawyer is not generally required merely to execute and file a complaint-affidavit, but legal assistance is valuable for choosing venue, identifying the correct respondents, proving each element, authenticating electronic evidence, and calculating deadlines. Those seeking legal aid may contact the Integrated Bar of the Philippines National Center for Legal Aid or inquire with the appropriate government legal-assistance office about eligibility.

Frequently asked questions

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

Yes, but give investigators every known identifier and explain how it relates to the transaction. Do not invent a name or accuse the registered account owner without evidence of participation. NBI or police assistance may be necessary to obtain subscriber, financial, or device records through lawful process.

Is a demand letter always required?

No. It is not a universal element of every form of estafa. It can nevertheless be important evidence in misappropriation cases. For dishonored-check cases, written notice and proof of receipt can be essential because Article 315(2)(d) and B.P. Blg. 22 contain different notice-and-payment rules.

Will the respondent be arrested as soon as I file?

No. A complaint begins an investigation. If the prosecutor files an Information, the judge independently evaluates judicial probable cause. Warrantless arrest is lawful only under the limited circumstances stated in Rule 113.

Can the criminal case recover my money?

The civil action arising from the offense is generally deemed included in the criminal case unless it is waived, reserved, or was previously filed, under Rule 111. Recovery still depends on proof, the final judgment, and the respondent’s available assets. Filing a complaint does not guarantee reimbursement.

Does repayment automatically end the case?

No. Estafa is prosecuted in the name of the People of the Philippines. Repayment, settlement, or an affidavit of desistance may affect civil liability or the evaluation of the evidence, but it does not automatically compel the prosecutor or court to dismiss a public offense. Obtain legal advice before signing a settlement, release, waiver, or desistance.

What should I do if the complaint is dismissed?

Obtain the complete resolution and record the date you received it. Regular preliminary-investigation resolutions generally allow a motion for reconsideration within 15 days; expedited cases allow 10 calendar days; summary-investigation cases do not allow one under DOJ Circular No. 28. Further review is governed by DOJ appeal rules and depends on court jurisdiction. Seek counsel immediately rather than simply refiling the same complaint.
