Receiving a subpoena from the Office of the City or Provincial Prosecutor means a criminal complaint has been filed against you, and the prosecutor is conducting a preliminary investigation to determine if there is enough evidence to file formal charges in court. The subpoena usually comes with the complaint-affidavit and supporting documents, and it requires you to explain your side through a counter-affidavit. Under Philippine law, you have a strict but clear window to respond: ten (10) calendar days from receipt of the complete subpoena package. Acting quickly and correctly at this stage can prevent the case from moving forward or at least ensure your defenses are properly considered before any Information is filed in court.

This deadline applies in regular preliminary investigation proceedings handled by public prosecutors. It does not cover inquest proceedings (which apply when a person is arrested without a warrant and brought directly to the prosecutor). The rules aim to give every respondent a meaningful opportunity to be heard while keeping the process moving.

Legal Basis for the 10-Day Deadline

The primary authority comes from Rule 112, Section 3 of the Revised Rules of Criminal Procedure, as harmonized with the 2024 DOJ-National Prosecution Service Rules on Preliminary Investigation and Inquest Proceedings (Department Circular No. 015, Series of 2024). The Supreme Court, through A.M. No. 24-02-09-SC, aligned the older provisions of Rule 112 with these updated DOJ rules.

The key provision states that within ten (10) days from receipt of the subpoena together with the complaint and supporting affidavits and documents, the respondent shall submit his or her counter-affidavit and those of any witnesses, plus other supporting documents. The counter-affidavit must be subscribed and sworn to before an authorized officer.

The 2024 DOJ rules maintain this minimum 10-day period while introducing a more structured process. The subpoena now typically sets a preliminary investigation hearing within 30 days from the prosecutor’s receipt of the case records. During or in connection with that hearing, the respondent submits the counter-affidavit. The overall preliminary investigation must generally be resolved within 60 days (extendable by 30 days for complex or capital cases).

These rules protect due process while promoting efficiency. Jurisprudence emphasizes that the period begins only upon proper service of the complete set of documents. If attachments are missing, the clock may not start until you receive everything (see principles from cases such as Sayson v. People).

How the 10 Calendar Days Are Counted

The period uses calendar days, not working days.

The day you actually receive the subpoena and complete attachments is not counted as Day 1.
Day 1 begins the following calendar day.
You must file on or before the 10th day.
If the 10th day falls on a Saturday, Sunday, or legal holiday, the deadline automatically moves to the next working day (per Rule 22 of the Rules of Court).

Example: If you receive the subpoena package on a Monday, June 1, Day 1 is Tuesday, June 2. Your deadline is Thursday, June 11 (or the next working day if June 11 is a holiday).

Service can occur personally, by registered mail, private courier, or electronic means (under applicable DOJ circulars). Substituted service is allowed in some cases of evasion. For multiple respondents, each person’s 10-day period runs individually from their own receipt.

What Happens If You Do Not File on Time

If you miss the deadline without an approved extension, the investigating prosecutor may resolve the complaint based solely on the complainant’s evidence and affidavits. This is called an ex parte resolution. You lose the chance to present your side, witnesses, or documentary evidence at this critical early stage.

In practice, a well-prepared counter-affidavit that directly addresses each allegation, provides credible explanations or alibis supported by documents or witness statements, and raises legal defenses (such as prescription, lack of elements of the crime, or self-defense) can lead to a finding of no probable cause and outright dismissal. Missing this opportunity often means the prosecutor will file an Information in the Regional Trial Court or Municipal Trial Court, after which a warrant of arrest may issue and the full criminal trial process begins.

Late filing is sometimes accepted if you file a motion with strong justification and the prosecutor exercises discretion in the interest of justice, but there is no guarantee. It is always safer to meet the original deadline or secure an extension in advance.

Step-by-Step Guide to Filing Your Counter-Affidavit

Act immediately upon receipt. Note the exact date, time, and manner of service. Check that you received every page of the complaint-affidavit and all annexes (photos, medical certificates, affidavits of witnesses, etc.). If anything is missing, send a written request (with proof of service) for the complete documents right away. This protects your timeline.
Consult a lawyer right away. A licensed Philippine attorney experienced in criminal procedure can review the complaint, identify weaknesses, and draft a strong response. Self-representation is possible but risky—admissions or poorly worded denials can hurt your case later.
Gather your evidence and witnesses. Collect documents, messages, receipts, CCTV footage, or other proof that supports your defense. Prepare sworn affidavits from witnesses who have personal knowledge of the facts. These must be based on personal knowledge and not hearsay.
Draft the counter-affidavit. Write a clear, point-by-point response to the allegations in the complaint. State facts, attach supporting evidence, and explain why the complaint should be dismissed. Avoid unnecessary admissions. Include a verification and jurat (sworn statement).
Have it properly sworn. The counter-affidavit must be subscribed and sworn to before the investigating prosecutor (often preferred and may require personal appearance at the hearing), any government official authorized to administer oaths, or a notary public. Under the 2024 rules, personal appearance can sometimes be waived if the document is properly notarized.
File and serve. Submit the original to the prosecutor’s office handling the case, together with proof that you served a copy on the complainant (or their counsel). Keep extra copies with receiving stamps or acknowledgment receipts for your records. Electronic filing may be allowed in some offices—confirm with the specific prosecutor’s office.
Attend any clarificatory hearing. The prosecutor may set questions to clarify points in the affidavits. Be prepared and bring your lawyer.
Follow up on the resolution. After all submissions (including any reply-affidavit from the complainant and rejoinder), the prosecutor resolves the case. You will receive a copy of the resolution.

Common Pitfalls and Real-Life Scenarios

Many respondents underestimate the 10-day period or assume they can “explain everything in court later.” By then, the damage is often done—an Information has already been filed.

Frequent mistakes include:

Ignoring the subpoena entirely (leads to ex parte resolution against you).
Filing only a motion to dismiss without a counter-affidavit (generally not allowed; you must still submit the counter-affidavit).
Submitting an unsworn or poorly prepared document.
Failing to serve a copy on the complainant.
Waiting until the last day to ask for an extension (prosecutors are less likely to grant it).

For overseas Filipinos (OFWs) and foreigners: Service may occur via email, courier, or through family members in the Philippines. You can execute your counter-affidavit before a Philippine consul or embassy officer abroad (this carries the same weight as a local notarization in many cases). Time differences, courier delays, and the need to coordinate with a Philippine-based lawyer are common challenges. Foreign documents attached as evidence may require apostille authentication under the Apostille Convention if they come from a member country. Constitutional rights to due process and equal protection apply equally to everyone in the Philippines, regardless of nationality.

Other practical realities: In high-volume offices (Metro Manila, Cebu, Davao), resolutions can take the full 60 days or longer due to caseloads. A strong counter-affidavit submitted early often prompts the prosecutor to look more closely at the complainant’s evidence and can result in dismissal before the case reaches court.

Frequently Asked Questions

How many days do I really have to file a counter-affidavit after receiving a subpoena?
You have ten (10) calendar days from the day after you receive the complete subpoena package (complaint plus all supporting documents). The exact counting follows Rule 22 of the Rules of Court.

Can I request an extension to file my counter-affidavit?
Yes. File a written motion before the original deadline explaining valid reasons (such as needing more time to gather documents, medical reasons, or overseas location). Prosecutors may grant 15 days or more on meritorious grounds under DOJ guidelines. Do not assume approval—file early and serve a copy on the complainant.

Do I need to appear in person to submit my counter-affidavit?
Under the 2024 DOJ rules, you generally submit it in connection with the preliminary investigation hearing. Personal appearance can sometimes be waived if the counter-affidavit is properly sworn before a notary or authorized officer. Confirm with the specific prosecutor’s office.

What if the subpoena I received is missing some of the complainant’s evidence?
Request the complete documents in writing immediately. The 10-day period typically starts only when you have received everything necessary to prepare an informed response.

Will filing a counter-affidavit automatically dismiss the case?
No, but a clear, evidence-backed counter-affidavit that shows the complaint lacks merit or fails to establish probable cause significantly increases the chances of dismissal at the preliminary investigation stage.

What happens if I completely ignore the subpoena and deadline?
The prosecutor can resolve the case based only on the complainant’s side. This often leads to the filing of an Information in court and a possible warrant of arrest. It is one of the worst strategic choices you can make.

Are the rules different if I am a foreigner or living abroad?
The legal deadline and rights are the same. Practical differences involve service of documents, executing the affidavit before a Philippine consul, and the possible need for apostilled foreign evidence. Engage a Philippine lawyer early to handle filings and coordination.

After I file my counter-affidavit, what happens next?
The complainant may file a reply-affidavit. The prosecutor may hold a clarificatory hearing. The case is then submitted for resolution. You will receive a copy of the prosecutor’s resolution. If probable cause is found, an Information is filed in court.

Is there a filing fee for the counter-affidavit?
No filing fee is required for submitting a counter-affidavit during preliminary investigation.
