If you received a subpoena from a Philippine prosecutor, the safest working rule is this: check the exact date written in the subpoena, but you should generally be given at least ten (10) days from receipt of the subpoena and complaint-affidavit to file your counter-affidavit in a regular preliminary investigation. Do not treat the subpoena as a mere invitation. Your counter-affidavit is often your first real chance to answer the accusation before the prosecutor decides whether to dismiss the complaint or file an Information in court.

What a Prosecutor’s Subpoena Means in a Criminal Complaint

A subpoena from the Office of the City Prosecutor, Provincial Prosecutor, or the Department of Justice usually means a criminal complaint has been filed against you and the prosecutor is conducting a preliminary investigation.

A preliminary investigation is not yet a trial. There is no judge deciding guilt or innocence. The prosecutor is deciding whether the case should proceed to court.

In simple terms, the prosecutor is asking:

Is there enough evidence that a crime was committed?
Is there enough evidence linking the respondent to that crime?
Is the evidence strong enough to justify filing the case in court?

Under the 2024 DOJ-NPS Rules on Preliminary Investigations and Inquest Proceedings, the DOJ-National Prosecution Service now uses the standard of prima facie evidence with reasonable certainty of conviction in preliminary investigations and inquests. The Supreme Court upheld the validity of these DOJ rules in Meking v. Remulla, G.R. No. 280455, November 11, 2025, recognizing that preliminary investigation by prosecutors is an executive function, not a court procedure.

Your counter-affidavit is your sworn written answer. It should contain your defenses, your version of events, and your supporting documents and witness affidavits. It is usually much more important than simply appearing at the prosecutor’s office and verbally denying the accusation.

How Many Days Do You Have to File a Counter-Affidavit?

For a regular preliminary investigation before DOJ-NPS prosecutors, the subpoena should set a preliminary investigation hearing date and direct the respondent to submit the counter-affidavit and witness affidavits on that date. The hearing date for submission must be at least ten (10) days from receipt of the subpoena and the complaint-affidavit. The subpoena must include the complaint-affidavit and attachments. For voluminous records, the prosecutor must set a separate date for the respondent to pick up the records, and that date must be at least ten (10) days before the preliminary investigation hearing. (Scribd)

In practice, this means:

Situation	Practical deadline
Subpoena states a specific date for submission	Follow the date in the subpoena.
Subpoena and complaint-affidavit were received together	Count from receipt, but file on or before the date stated in the subpoena.
Attachments are incomplete or missing	Immediately request the missing attachments in writing and ask that the period be counted from receipt of the complete records.
Records are voluminous	Check if the subpoena gives a separate pick-up date for records. Document when you actually received or accessed them.
Last day falls on a Saturday, Sunday, or legal holiday	Under Rule 22 on computation of time, the deadline generally moves to the next working day when the last day falls on a Saturday, Sunday, or legal holiday. (Supreme Court E-Library)

A common mistake is thinking, “I have ten working days.” Unless the subpoena or applicable rule clearly says working days, count conservatively. Treat the period as running continuously and aim to file early.

Legal Basis for the Timeline

Regular Preliminary Investigation Under the 2024 DOJ-NPS Rules

The 2024 DOJ-NPS Rules apply to preliminary investigations and inquest proceedings conducted by prosecution offices under the National Prosecution Service of the Department of Justice, as organized under Republic Act No. 10071, the Prosecution Service Act of 2010. The DOJ rules cover regular preliminary investigation for crimes or offenses where the penalty prescribed by law is at least six (6) years and one (1) day, without regard to fine. (Scribd)

This matters because many older Philippine legal articles still discuss the former Rule 112 threshold of at least four (4) years, two (2) months, and one (1) day. For DOJ-NPS prosecutors, the 2024 DOJ-NPS Rules now govern, and the Supreme Court has recognized the DOJ’s authority to issue those rules for prosecutorial proceedings.

Under the regular DOJ-NPS process:

The complaint-affidavit is filed with the prosecution office.
The office checks sufficiency in form and completeness of evidence.
If the prosecutor finds ground to proceed, a subpoena is issued.
The subpoena sets the hearing date and directs the respondent to submit a counter-affidavit.
The hearing date must give the respondent at least ten (10) days from receipt of the subpoena and complaint-affidavit.
The counter-affidavit is filed with supporting documents and witness affidavits.
The prosecutor may submit the case for resolution, require reply/rejoinder affidavits when allowed, or conduct clarificatory questioning. (Scribd)

Older Rule 112 of the Rules of Criminal Procedure

Rule 112 of the Revised Rules of Criminal Procedure historically provided that the respondent submits counter-affidavits and supporting documents within ten (10) days from receipt of the subpoena and complaint documents. It also provided that if the respondent cannot be subpoenaed or fails to submit counter-affidavits within the period, the investigating officer may resolve the complaint based on the complainant’s evidence. (Lawphil)

Because the DOJ-NPS Rules have changed important parts of the prosecutor-led process, Rule 112 should now be read carefully and, for DOJ prosecutors, only in harmony with the 2024 DOJ-NPS Rules and Supreme Court rulings recognizing DOJ authority over preliminary investigations.

Expedited Preliminary Investigation and Summary Investigation

Not all prosecutor proceedings are regular preliminary investigations. Under DOJ Department Circular No. 28, series of 2024, the DOJ also issued rules on summary investigation and expedited preliminary investigation for less serious offenses. Expedited preliminary investigation generally covers offenses punishable by one (1) year and one (1) day up to six (6) years in certain first-level court cases, while regular preliminary investigation covers offenses at least six (6) years and one (1) day or cases otherwise cognizable by the Regional Trial Court. (AAQDD Law)

In expedited preliminary investigation, the subpoena sets a hearing date that must not exceed fifteen (15) calendar days from the investigating prosecutor’s receipt of the complete case records, and the respondent is directed to submit the counter-affidavit on the hearing date. No reply-affidavit or rejoinder-affidavit is entertained, although a clarificatory hearing may be conducted within five (5) calendar days from submission of the counter-affidavit when needed. Motions for extension are also listed among prohibited pleadings in these expedited proceedings. (Scribd)

Ombudsman Cases

If the subpoena or order came from the Office of the Ombudsman, especially for cases involving public officers, different procedural rules may apply. Under the Rules of Procedure of the Office of the Ombudsman, the investigating officer may direct the respondent to submit counter-affidavits and controverting evidence within ten (10) days from receipt of the order, with proof of service on the complainant. (Ombudsman)

Do not assume that a DOJ subpoena, Ombudsman order, barangay notice, police invitation, and court subpoena all follow exactly the same deadline.

How to Count the 10-Day Period

The usual way to count legal periods in Philippine procedure is:

Exclude the day of receipt.
Start counting the next day.
Include the last day.
If the last day falls on a Saturday, Sunday, or legal holiday, file on the next working day. (Supreme Court E-Library)

Example:

Event	Date
You received the subpoena and complaint-affidavit	Monday, March 3
Day 1	Tuesday, March 4
Day 10	Thursday, March 13
Practical filing deadline	On or before March 13, unless the subpoena gives a later valid hearing date

If the subpoena states a specific hearing date, follow that date. If the date gives you fewer than ten days from actual receipt of the subpoena and complaint-affidavit in a regular preliminary investigation, file a written manifestation or request immediately explaining the short notice and asking for a resetting or reasonable opportunity to file.

Step-by-Step Guide After Receiving the Subpoena

1. Record the Exact Date, Time, and Manner of Receipt

Immediately write down:

Date and time you received the subpoena
Who received it
How it was served: personal delivery, registered mail, courier, email, or through an authorized representative
Whether the complaint-affidavit and attachments were included
Whether the subpoena states a physical or virtual hearing

Keep the envelope, registry notice, courier proof, email header, or acknowledgment receipt. The deadline usually depends on proof of receipt.

2. Check if the Complaint Package Is Complete

A proper subpoena package should normally include:

The complaint-affidavit
Affidavits of witnesses
Supporting documents
Attachments mentioned in the complaint
Hearing date, time, and venue or virtual instructions

If attachments are missing, do not wait until the deadline. File a short written request with the prosecution office asking for copies or access to the missing records. If the records are voluminous, ask how and when you may inspect or pick them up.

3. Identify the Exact Charge and Penalty

Look at the offense named in the complaint. Examples:

Estafa under the Revised Penal Code
Cyberlibel under Republic Act No. 10175, the Cybercrime Prevention Act
Violence against women under Republic Act No. 9262
Anti-graft cases under Republic Act No. 3019
Bouncing Checks Law cases under Batas Pambansa Blg. 22
Qualified theft, falsification, grave threats, unjust vexation, or other offenses

The penalty affects whether the case goes through regular preliminary investigation, expedited preliminary investigation, summary investigation, or another special procedure.

4. Prepare the Counter-Affidavit Around the Elements of the Offense

A strong counter-affidavit does not merely say, “I deny the allegations.” It should answer the legal elements of the alleged offense.

For example:

In estafa, address deceit, damage, and intent.
In theft, address taking, ownership, intent to gain, and absence of consent.
In cyberlibel, address authorship, publication, identifiability, malice, and truth or privileged communication when applicable.
In VAWC cases, address the alleged relationship, acts complained of, evidence, and context carefully.

Attach documents that directly support your defense.

5. Prepare Witness Affidavits Early

If another person’s statement helps your defense, that person should usually execute a separate affidavit.

Examples of useful witness affidavits:

A co-worker confirming you were not present at the alleged scene
A bank officer explaining transaction records
A barangay official confirming prior settlement attempts
A technician explaining CCTV, device logs, or message records
A person present during the alleged incident

Do not rely on witnesses appearing later in court. Preliminary investigation is primarily document-based.

6. Organize Supporting Evidence

Useful attachments may include:

Screenshots with date, time, sender, recipient, and URL when relevant
Bank statements or remittance slips
Contracts, receipts, invoices, delivery records
CCTV stills or certification from the custodian
Company IDs, attendance logs, payroll records
Medical records when relevant
Barangay blotter, police reports, or prior settlement documents
Immigration stamps, boarding passes, travel records, or GPS/location proof

Label attachments clearly: “Annex A,” “Annex B,” and so on. Prosecutors handle many cases; a well-organized submission is easier to evaluate.

7. Have the Counter-Affidavit Properly Sworn

Under the DOJ-NPS rules, a counter-affidavit is a written statement of the respondent indicating defenses and must be subscribed and sworn before a prosecutor, a government official authorized to administer oath, or, if unavailable, a notary public. In regular preliminary investigation, the respondent or authorized representative files the original and two duplicate copies for the prosecution office and furnishes the complainant or each complainant a copy. (Scribd)

Be careful with sworn statements. A knowingly false statement in a sworn affidavit can expose a person to possible perjury issues under Article 183 of the Revised Penal Code.

8. File Before the Deadline and Secure Proof

When filing, bring:

Original counter-affidavit
Required duplicate copies
Copies for complainant or proof of service
Annexes and witness affidavits
Copy of the subpoena
Valid IDs used for notarization or oath
Written authority or Special Power of Attorney if someone files for you

Ask for a receiving copy stamped with date and time. For email or electronic filing, keep the sent email, attachments, delivery confirmation, and any acknowledgment from the prosecution office.

Can You Ask for an Extension?

Sometimes, yes — but do not assume it will be granted.

Under the DOJ-NPS rules for regular preliminary investigation, requests for extension are generally restricted, but may be allowed when the interest of justice demands it, such as when a party needs reasonable time to engage counsel, examine voluminous records, verify authenticity, or study complicated factual or legal issues. (Scribd)

A good request for extension should:

Be filed before the deadline
Explain the specific reason
State the exact additional time requested
Attach proof, such as missing records, voluminous documents, travel proof, hospitalization, or late receipt
Avoid vague reasons like “busy schedule” or “need more time”

For expedited preliminary investigation, be much more cautious. The DOJ rules on expedited proceedings list motions for extension among prohibited pleadings. (Scribd)

What Happens If You Do Not File a Counter-Affidavit?

If you fail to file without a justifiable reason, the prosecutor may consider the case submitted for resolution based on the available evidence. Under the DOJ-NPS rules, if despite receipt of subpoena at the respondent’s last known address the respondent fails to appear or file a counter-affidavit without justifiable reason, the investigating prosecutor may submit the case for resolution. (Scribd)

This is risky because:

The complainant’s version may go unanswered.
Your documents may not be considered.
The prosecutor may recommend filing the Information in court.
Once filed in court, the case becomes more expensive, stressful, and public.
You may later need to seek reconsideration, review, or other remedies instead of preventing filing at the earliest stage.

Missing the deadline does not automatically mean guilt. But it can remove your best early opportunity to stop a weak complaint before it becomes a court case.

Do You Need to Personally Appear?

In regular DOJ preliminary investigation, the respondent’s personal appearance may be dispensed with if the counter-affidavit was subscribed and sworn before a prosecutor, authorized government officer, or notary public. The respondent or an authorized representative may file the original and duplicate copies. (Scribd)

Still, read the subpoena carefully. If it requires appearance, or if the prosecutor sets clarificatory questioning, non-appearance can create avoidable problems. If you cannot attend because you are abroad, sick, detained elsewhere, or in another province, file a written explanation with supporting proof.

Special Issues for Filipinos Abroad and Foreign Respondents

If you are overseas when you receive notice of a Philippine criminal complaint, time becomes the main problem. Preparing, notarizing, apostilling, couriering, and filing documents can easily consume the whole period.

Practical options include:

Execute the counter-affidavit before a Philippine Embassy or Consulate that offers consular notarization.
Execute the affidavit before a local notary and secure an apostille from the competent authority if the country is an Apostille Convention member.
If the country is not an Apostille country, ask the relevant Philippine post or prosecutor’s office what authentication will be accepted.
Send a scanned copy first if electronic filing is allowed, then transmit originals as required.
Authorize someone in the Philippines through a Special Power of Attorney to file and receive documents.

Philippine consulates can notarize private documents such as affidavits for use in the Philippines, and documents notarized by a Philippine Embassy or Consulate are generally valid for Philippine use without further apostille. Public documents with apostille certificates from Apostille Convention countries are also accepted in the Philippines without consular authentication. (Philippine Embassy)

If your affidavit or supporting document is not in English or Filipino, prepare a proper English translation. Prosecutors may not act on foreign-language documents they cannot evaluate.

Common Mistakes That Hurt Respondents

Filing a Motion to Dismiss Instead of a Counter-Affidavit

Under the DOJ-NPS rules, a motion to dismiss in lieu of a counter-affidavit is generally not allowed, except when it is verified by the respondent and contains the respondent’s defenses, in which case it may be treated as a counter-affidavit. (Scribd)

This means a technical motion that does not address the facts can backfire.

Filing a Bare Denial

A counter-affidavit that says only “I deny everything” is usually weak. Prosecutors need facts and evidence. Explain what actually happened, attach documents, and address the complaint point by point.

Ignoring the Attachments

The complaint may refer to screenshots, receipts, contracts, or medical reports. If you do not review them, you may miss important inconsistencies.

Missing Proof of Service

The DOJ-NPS rules require the respondent to furnish the complainant or each complainant a copy. File proof that you did so. (Scribd)

Waiting Until the Last Day to Notarize

Many respondents finish the affidavit on the deadline, then discover the notary is unavailable, the prosecutor is out, or the office closes early. Complete notarization or oath-taking before the deadline.

Treating a Police Invitation Like a Prosecutor Subpoena

A police invitation, barangay summons, prosecutor subpoena, Ombudsman order, and court subpoena have different effects. Read who issued the document.

Forgetting Barangay Conciliation Issues

For minor disputes between individuals in the same city or municipality, barangay conciliation under the Katarungang Pambarangay system may affect whether a complaint can proceed. The barangay process generally covers many disputes, but excludes, among others, offenses punishable by imprisonment exceeding one year or a fine exceeding ₱5,000, offenses with no private offended party, and cases requiring urgent action. (Lawphil)

What Happens After You File the Counter-Affidavit?

After receiving your counter-affidavit and confirming that the complainant has been furnished a copy, the prosecutor may:

Submit the case for resolution.
Set a physical or virtual clarificatory hearing within ten (10) calendar days if facts or issues need clarification.
Require a reply-affidavit if the counter-affidavit raises new material issues.
Allow a rejoinder-affidavit from the respondent, which is generally the last pleading. The filing of reply and rejoinder affidavits must not exceed ten (10) calendar days from receipt of the pleading being answered. (Scribd)

In regular DOJ preliminary investigation, administrative timelines aim for prompt resolution. The investigating prosecutor transmits the recommendatory resolution and Information, if any, to the head of office for approval; the head of office acts on it; and the resolution is promulgated after approval. In practice, actual timelines vary depending on office workload, case complexity, number of respondents, volume of records, and whether motions or clarificatory hearings are allowed. (DivinaLaw)

If the resolution is adverse, the aggrieved party may generally file a motion for reconsideration within fifteen (15) days from receipt in regular preliminary investigation cases under the DOJ-NPS rules. (Scribd)

Practical Checklist Before Filing

Before filing your counter-affidavit, check the following:

Item	Why it matters
Date of receipt noted	Determines deadline.
Complete complaint and attachments reviewed	You cannot properly answer what you have not seen.
Correct prosecutor office and case number used	Avoids misfiling.
Offense and legal elements identified	Helps focus the defense.
Counter-affidavit sworn properly	Unsworn statements may be disregarded.
Witness affidavits attached	Supports your version with independent facts.
Documentary evidence labeled	Makes review easier for the prosecutor.
Copies prepared	DOJ rules require original and duplicate copies, plus copies for complainant.
Proof of service attached	Shows the complainant was furnished a copy.
Receiving copy secured	Proves timely filing.

Frequently Asked Questions

How many days do I have to file a counter-affidavit after receiving a prosecutor subpoena?

In a regular DOJ preliminary investigation, the subpoena should set a submission or hearing date that gives you at least ten (10) days from receipt of the subpoena and complaint-affidavit. Always follow the exact date in the subpoena unless you have a valid written resetting or extension.

Is the 10-day period counted as calendar days or working days?

Count conservatively as calendar days unless the subpoena or applicable rule clearly says otherwise. Exclude the day of receipt and include the last day. If the last day falls on a Saturday, Sunday, or legal holiday, the deadline generally moves to the next working day under Rule 22.

What if I received the subpoena but not the complaint-affidavit or attachments?

Immediately file a written request for the missing documents and ask that your period be counted from receipt of the complete subpoena package. Keep proof of your request. The DOJ-NPS rules require the subpoena to include the complaint-affidavit and attachments.

Can I ignore the subpoena if the complaint is false?

No. Even a false or weak complaint must be answered properly. If you ignore the subpoena, the prosecutor may resolve the case based on the complainant’s evidence.

Can I file a motion to dismiss instead of a counter-affidavit?

Generally, no. Under the DOJ-NPS rules, a motion to dismiss in lieu of a counter-affidavit is not allowed except when verified by the respondent and containing the respondent’s defenses, in which case it may be treated as a counter-affidavit.

Do I need a lawyer to file a counter-affidavit?

A respondent may physically file without counsel, but a counter-affidavit in a criminal complaint affects liberty, reputation, immigration status for foreigners, employment, professional licenses, and future court exposure. The document should be prepared carefully around the facts, legal elements, and evidence.

Can someone else file my counter-affidavit for me?

Yes, in many cases an authorized representative may file it, especially if the counter-affidavit was properly sworn and the representative has written authority. Check the subpoena and the prosecution office’s filing requirements.

What if I am abroad?

You may execute the affidavit before a Philippine Embassy or Consulate, or use a locally notarized and apostilled document when applicable. Because overseas notarization, apostille, courier, and translation take time, act immediately and preserve proof of your location and receipt date.

What happens after I file my counter-affidavit?

The prosecutor may submit the case for resolution, set a clarificatory hearing, or require further affidavits when allowed. If the prosecutor recommends filing the case in court, you may have post-resolution remedies such as a motion for reconsideration within the applicable period.

Does filing a counter-affidavit mean I admit the prosecutor’s jurisdiction?

Filing a counter-affidavit generally means you are answering the complaint and presenting defenses. If you have jurisdictional or procedural objections, raise them clearly in the counter-affidavit or in a verified pleading that also states your defenses, so you do not lose the chance to answer the facts.
