If you have just received a subpoena from a fiscal or public prosecutor in the Philippines, your top concern is almost certainly the deadline to file a counter-affidavit. This document is your sworn written response to the criminal complaint filed against you. Under the rules that govern preliminary investigations today, you are generally given a minimum of ten (10) calendar days from actual receipt of the subpoena and the attached complaint-affidavit plus supporting documents to submit your counter-affidavit. The subpoena itself will usually state the exact hearing date or deadline, and it must give you at least this 10-day window.

This article explains the current rules in plain language, what the 10-day period really means in practice, the full step-by-step process, common mistakes that can hurt your case, and what to do in real-life situations many Filipinos and foreigners face.

What a Fiscal Subpoena Means in a Preliminary Investigation

A fiscal subpoena is an official order from the prosecutor’s office (Office of the City or Provincial Prosecutor, or a state prosecutor) requiring you to respond to a criminal complaint. It is issued during the preliminary investigation stage — the screening process before any formal criminal case is filed in court.

The prosecutor reviews the complaint to decide whether there is enough evidence under the current standard of prima facie evidence with reasonable certainty of conviction to file an Information in court. Your counter-affidavit is your main opportunity to present your side, attach evidence, and explain why the complaint should be dismissed.

Preliminary investigation applies to offenses punishable by imprisonment of at least six (6) years and one (1) day (under the 2024 rules for regular cases). Lighter offenses may fall under summary or expedited procedures with their own shorter timelines.

Legal Basis for the 10-Day Period

The 2024 DOJ-NPS Rules on Preliminary Investigation and Inquest Proceedings (Department Circular No. 015, series of 2024) now primarily govern these cases. The Supreme Court has upheld the DOJ’s authority to issue these rules, and inconsistent provisions of the older Rule 112 of the Revised Rules of Criminal Procedure are no longer controlling for National Prosecution Service proceedings.

These new rules carry forward the long-standing requirement that respondents be given a minimum of ten (10) days from receipt of the subpoena to submit a counter-affidavit. The subpoena sets the preliminary investigation hearing (usually within 30 days of case assignment) and directs you to file your counter-affidavit by or at that hearing.

In expedited or summary investigation cases for lighter offenses (covered by related DOJ Circular No. 028), the period to submit a counter-affidavit can be as short as five (5) calendar days in some instances. Always check the exact wording and deadline written on the subpoena you received.

How the 10-Day Period Is Counted

The clock starts upon actual receipt of the subpoena (personal service, or valid substituted service at your last known address or through your counsel).
It is generally calendar days, not working days.
If the 10th day falls on a Saturday, Sunday, or legal holiday, you may file on the next working day.
The subpoena will usually specify the exact date and time of the hearing or the submission deadline. Follow what it says — it controls your case.

Important: Day 1 is typically the day after you actually receive the documents. File early rather than on the last possible day.

Step-by-Step: What to Do After Receiving the Subpoena

Read everything carefully right away. Note the exact deadline, hearing date, and instructions. Check what documents are attached (complaint-affidavit, affidavits of witnesses, photos, contracts, medical reports, etc.).
Secure legal help immediately. Time is short. If you cannot afford a private lawyer, go to the nearest Public Attorney’s Office (PAO) branch. Many PAO offices prioritize urgent preliminary investigation cases. Bring the subpoena and all attachments.
Prepare your counter-affidavit. This is a sworn statement. It should:
- Clearly admit or deny each material allegation in the complaint.
- Present your version of events with specific details and dates.
- Attach supporting evidence (documents, photos, messages, receipts) and affidavits from your witnesses.
- Include any legal defenses (prescription, lack of jurisdiction, self-defense, etc.).
Have it properly sworn. You can swear it before the investigating prosecutor, any government official authorized to administer oaths, or a notary public. You do not always need to appear in person at the hearing if your counter-affidavit is validly sworn.
File and serve copies. Submit the original to the prosecutor’s office indicated in the subpoena (usually the same office that issued it). Furnish a copy to the complainant or their counsel as directed. In some offices, electronic filing via official email is now allowed, especially if an extension was granted.
Attend the hearing if required. The subpoena will tell you the date. At the hearing the prosecutor may ask clarificatory questions. If you have already submitted a complete counter-affidavit, your presence may be waived.
Keep records. Keep stamped copies of everything you filed and proof of service on the complainant.

What Happens If You Miss the Deadline or Do Not File

If you fail to submit a counter-affidavit within the period given, the prosecutor will resolve the complaint based on the complainant’s evidence alone. This often leads to a resolution finding sufficient basis to file a criminal case in court. You lose the chance to present your side at this early stage.

You may still file a motion for reconsideration (usually within 15 days of receiving the resolution) or raise your defenses during trial, but it is far better to participate fully from the beginning. Ignoring the subpoena is one of the most common and costly mistakes.

Common Pitfalls and Real-Life Scenarios

Last-minute preparation. Many people wait until the final days and submit weak, general denials without evidence. Strong, specific, and well-documented counter-affidavits have a much better chance of leading to dismissal.
Thinking you can just explain orally. The rules require a written counter-affidavit. Verbal explanations at the hearing are supplementary at best.
Filing a motion to dismiss instead. In most cases you cannot substitute a motion to dismiss for a counter-affidavit. Submit the counter-affidavit.
OFWs and Filipinos abroad. If the subpoena was served on family members in the Philippines or at your last known address, it may still be valid. Engage a Philippine lawyer immediately (many handle cases remotely via video or through local associates). Documents executed abroad usually need apostille authentication to be given full weight.
Foreigners or dual citizens. The same 10-day (or subpoena-stated) period applies once validly served. Constitutional restrictions on land ownership or other matters do not affect criminal procedure deadlines. Engage counsel familiar with both Philippine criminal procedure and any consular or immigration implications.
Requesting an extension. You may file a written motion for extension before the deadline expires, citing valid reasons (voluminous records, difficulty locating witnesses, recent receipt of documents, health issues). The prosecutor has discretion to grant or deny it. Do not assume it will be granted.
Multiple respondents. Each person usually receives their own subpoena and must file their own counter-affidavit. One person’s filing does not automatically cover others.

Documents You Will Need and Practical Tips

Core documents for your counter-affidavit package:

Your sworn counter-affidavit (original + copies)
Affidavits of your witnesses (sworn)
Supporting documents (photocopies; bring originals to hearing if needed)
Proof of service on the complainant
Special Power of Attorney if someone else will file on your behalf

Practical tips:

Start drafting immediately — even a basic outline helps when you meet your lawyer.
Be factual and specific. Avoid emotional language or personal attacks on the complainant.
Organize attachments clearly (label them as Annex “A”, “B”, etc.).
Notarization fees are modest (usually a few hundred pesos). Some prosecutors’ offices allow swearing before them at no extra cost.
Keep digital scans of everything.

Frequently Asked Questions

Can I get an extension to file my counter-affidavit?
Yes, you may request one in writing before the deadline if you have a good reason (such as needing time to gather documents or witness statements). File the motion early and explain why the extension is necessary. Approval is not automatic.

Do I have to appear personally at the preliminary investigation hearing?
Not necessarily. If your counter-affidavit is properly sworn before a notary or authorized official, the rules often allow the case to proceed without your personal appearance, unless the prosecutor requires clarificatory questions.

What if I never received the subpoena or it was left with a family member?
Validity of service depends on the circumstances and whether it complied with rules on substituted service. Contact the prosecutor’s office immediately and consult a lawyer. Do not ignore it — the case may still move forward.

Is the period 10 working days or calendar days?
It is generally calendar days. The subpoena you received controls — read it carefully for the exact wording and any specific date given.

Can I just submit a short explanation or letter instead of a formal counter-affidavit?
No. The rules require a sworn counter-affidavit. A simple letter or unsworn explanation usually will not be accepted as compliance.

What evidence should I attach to my counter-affidavit?
Anything that supports your defense: messages, photos, videos, receipts, contracts, medical records, police blotter entries, witness statements, or expert opinions. The stronger and more organized your evidence, the better your chances at this stage.

Does filing a counter-affidavit mean I am admitting anything?
No. It is your opportunity to deny the accusations and present your defense. Many cases are dismissed after a well-prepared counter-affidavit.

I am a foreigner or living abroad — does the same deadline apply?
Yes, once the subpoena is validly served. Engage Philippine counsel right away. You may need to execute documents abroad and have them apostilled for use in the proceedings.

What happens after I file the counter-affidavit?
The prosecutor may set a clarificatory hearing, require reply or rejoinder affidavits (usually within 10 days if allowed), or submit the case for resolution. The entire preliminary investigation should be resolved within 60 calendar days (extendable by up to 30 days in complex or capital cases).

Key Takeaways

You are generally given a minimum of 10 calendar days from actual receipt of the fiscal subpoena to submit your counter-affidavit under the current 2024 DOJ-NPS Rules.
The subpoena itself states the hearing date or deadline — follow its instructions precisely.
Act immediately: read the documents, consult a lawyer (PAO if needed), and prepare a detailed, evidence-backed counter-affidavit.
Missing the deadline usually means the prosecutor decides the case on the complainant’s evidence alone.
Strong preparation at this stage can lead to outright dismissal and avoid the stress and cost of a full court trial.
Keep records of everything and serve copies as required.
For complex situations (OFWs, foreigners, voluminous evidence, or requests for extension), professional legal assistance makes a real difference.

Receiving a subpoena is stressful, but responding properly and on time gives you a real chance to stop the case before it reaches court. Start today — the 10-day window passes quickly.
