Quick answer

A respondent who receives a subpoena during a preliminary investigation generally has ten days from receipt to submit a counter-affidavit, sworn under oath and accompanied by supporting witness affidavits and documentary evidence, addressing the allegations in the complaint point by point; failing to file within the period is treated as a waiver of the right to present evidence, and the prosecutor may then resolve the complaint based on the complainant’s evidence alone.

A counter-affidavit is the respondent’s formal, sworn answer to a criminal complaint during preliminary investigation — the stage before a case is filed in court where a public prosecutor decides whether there is probable cause to charge someone. Filing it correctly and on time is often the single most consequential thing a respondent does in the entire case, because it is frequently the only opportunity to be heard before the prosecutor decides whether to file an information in court.

Where the Counter-Affidavit Fits in the Process

Preliminary investigation under Rule 112 of the Rules of Court typically starts when a complainant files a complaint-affidavit, together with supporting evidence, before the prosecutor’s office. If the complaint is not dismissed outright for lack of merit on its face, the prosecutor issues a subpoena directing the respondent to submit a counter-affidavit. That subpoena, together with the complaint and its attachments, is what starts the clock.

Step 1: Get and Study the Complaint Against You

Before drafting anything, secure a complete copy of the complaint-affidavit and every document or piece of evidence attached to it. A respondent has the right to examine the evidence submitted by the complainant and obtain copies at his own expense. Read every allegation carefully — a counter-affidavit that responds only to the general accusation while ignoring specific claims (dates, amounts, alleged statements, photographs, receipts) leaves those specific claims effectively unrebutted in the record.

Step 2: Note the Ten-Day Deadline

The subpoena gives the respondent ten days from receipt to submit the counter-affidavit and any supporting evidence. This is a short window, especially once travel time, gathering documents, and coordinating with witnesses are factored in, so it is worth beginning work on the response as soon as the subpoena is received rather than waiting until the deadline is close. Whether an extension is available is at the discretion of the investigating prosecutor and is not something a respondent should assume will be granted.

Step 3: Draft the Counter-Affidavit

A counter-affidavit should generally include:

The counter-affidavit must be in the form of a sworn statement — signed by the respondent and subscribed and sworn to before the prosecutor, an authorized officer, or a notary public, consistent with how affidavits are executed for use in a preliminary investigation. An unsworn narrative or a mere letter is not a substitute for a proper counter-affidavit.

Step 4: File It and Serve a Copy on the Complainant

The counter-affidavit, together with its attachments, is filed with the prosecutor’s office handling the investigation, and a copy is furnished to the complainant or the complainant’s counsel, following whatever specific filing and service procedure the particular prosecutor’s office requires. Keep proof of filing and proof of service; these matter if a dispute later arises over whether and when the counter-affidavit was submitted.

Step 5: Attend a Clarificatory Hearing if the Prosecutor Sets One

The investigating prosecutor is not required to hold a hearing, but may, at his own discretion, set a clarificatory hearing if he believes there are matters that need to be clarified after reviewing the affidavits. Both parties may be asked to appear, but this is not a trial — the parties do not cross-examine each other, and the hearing is meant only to help the prosecutor clarify specific points already raised in the affidavits.

Step 6: Await the Resolution

After considering the complaint, the counter-affidavit, and any clarificatory proceedings, the prosecutor issues a resolution either finding probable cause — which leads to the filing of an information in court — or dismissing the complaint for lack of probable cause. A well-prepared counter-affidavit, filed on time with clear, specific, and well-supported responses, is the respondent’s main tool for influencing that determination before the case ever reaches a courtroom.

Preliminary Investigation Versus Inquest

Not every criminal case goes through the counter-affidavit process described above. When a person is arrested without a warrant, the case is ordinarily referred for inquest rather than a regular preliminary investigation, because the arresting officers must deliver the arrested person to the proper judicial authorities within a limited period under the Revised Penal Code’s rules on the delivery of detained persons. In an inquest, the inquest prosecutor evaluates whether the warrantless arrest and the evidence on hand justify filing a case, often within hours rather than the ten-day window given in an ordinary preliminary investigation. A person who was arrested without a warrant may still ask for a regular preliminary investigation instead of inquest, but doing so typically requires signing a waiver of the right to a prompt determination of probable cause and accepting continued detention while the regular process runs its course. Whether to ask for a regular preliminary investigation instead of proceeding through inquest is a decision worth making with the assistance of counsel, since it affects both the timeline and the person’s custodial status.

Common Mistakes That Weaken a Counter-Affidavit

A counter-affidavit that simply denies the allegations in general terms, without addressing the specific dates, amounts, documents, or statements the complainant relies on, tends to carry little weight with the prosecutor. Submitting the counter-affidavit without any of the supporting documents or witness affidavits referenced in it is another common weakness, since bare assertions are far less persuasive than assertions backed by something the prosecutor can independently examine. Respondents sometimes also submit a counter-affidavit that raises legal arguments better suited for trial — disputing the wording of the complaint, for instance — rather than focusing on whether probable cause exists on the facts; those arguments are usually more effective later, before the trial court, than at the preliminary investigation stage. Finally, missing the ten-day deadline because the respondent was gathering every possible piece of evidence before filing anything is a common and largely avoidable error — it is generally better to file a complete, well-organized counter-affidavit on time than a more exhaustive one late.

What Happens If You Miss the Deadline or Do Not File at All

Failing to submit a counter-affidavit within the period given is treated as a waiver of the respondent’s right to present evidence at that stage. The prosecutor is then left to evaluate probable cause based on the complainant’s evidence alone, without the benefit of the respondent’s side. This does not automatically mean a case will be filed, but it removes what is often the most direct opportunity to prevent one. A motion to dismiss is not treated as a substitute for a counter-affidavit — if there are genuine defenses or explanations to raise, they need to go into the counter-affidavit itself and its attachments.

What If the Respondent Was Never Properly Subpoenaed?

Preliminary investigation is meant to give the respondent a real opportunity to be heard before a case is filed. If a respondent learns of a complaint only after an information has already been filed in court, without having received a subpoena or an opportunity to submit a counter-affidavit, that is a due process concern that can be raised with the assistance of counsel — through the appropriate motion before the court where the case is pending, rather than something to try to fix informally after the fact.

Frequently Asked Questions

What happens if I do not submit a counter-affidavit in time? It is treated as a waiver of your right to present evidence at that stage, and the prosecutor may resolve the complaint and determine probable cause based solely on the complainant’s evidence.

Can I ask for an extension of the ten-day period to file my counter-affidavit? Whether to grant more time is within the discretion of the investigating prosecutor and is not guaranteed, so it is safer to begin preparing your response as soon as you receive the subpoena rather than relying on an extension.

Do I need a lawyer to file a counter-affidavit? It is not legally required, but strongly advisable, since the affidavit needs to address every material allegation with legally relevant defenses and properly presented evidence, and the outcome can determine whether a criminal case is filed against you in court.

What if I was never subpoenaed but a case was later filed against me in court? This raises a due process concern about the preliminary investigation itself, which should be raised through the proper motion before the court where the case is pending, with the assistance of counsel.
