An Affidavit of Complaint is a written declaration or statement made under oath by an individual (the complainant) alleging facts constituting an offense or legal violation. In the Philippine legal system, this document serves as the foundational step in initiating a criminal case, particularly for cases that require a formal complaint, such as in the filing of criminal charges or administrative complaints.

The Affidavit of Complaint is crucial because it initiates legal proceedings, allowing the prosecutor or relevant authorities to assess whether there is probable cause to proceed with a formal charge. Here’s a detailed breakdown of how to draft an effective Affidavit of Complaint in the Philippine context.

Key Elements of an Affidavit of Complaint

Title and Caption
- At the top of the document, the title “Affidavit of Complaint” should appear. This should be followed by the caption, which typically includes the name of the complainant and respondent (the party being accused), the case number, and the venue or jurisdiction where the affidavit is being filed (e.g., Office of the City Prosecutor of Manila).
Introduction
- The affidavit begins with an introductory statement, including the full name, age, civil status, address, occupation, and relationship (if applicable) of the complainant. It should also clearly state that the individual is executing the affidavit voluntarily and under oath.
Example:

“I, [Complainant’s Name], of legal age, single/married, Filipino, and a resident of [Complainant's Address], after being duly sworn to in accordance with law, hereby depose and state that…”
Statement of Facts
- The heart of the affidavit lies in the statement of facts. This section should detail the events leading to the complaint. The complainant must present a chronological account of the incidents in question, supported by facts that establish the commission of an offense or violation. It should be clear, concise, and free of ambiguity, as it will serve as the basis for the legal action.
- The statement should include:
  - Date, time, and place of the incident(s)
  - The specific actions of the respondent(s)
  - Any supporting evidence (e.g., documents, photographs, or witnesses)
  - How these actions have caused harm, whether physical, emotional, financial, or reputational
  - The law or regulation allegedly violated
Example:

“On or about [date], at [time], in [place], the respondent, [Respondent’s Name], did willfully, unlawfully, and feloniously [describe offense], by [details of the act].”
Legal Basis of the Complaint
- After narrating the facts, the complainant should state the legal grounds for the complaint. This includes citing the relevant law or provision that the respondent allegedly violated. This will help the prosecutor or the relevant authorities assess whether a case exists based on the facts and the law.
- For instance, in cases of theft, the complainant may cite the provisions of the Revised Penal Code (RPC), particularly Article 308 (Theft).
Example:

“The act of the respondent is a violation of Article 308 of the Revised Penal Code, which penalizes theft.”
Prayer for Relief
- In this section, the complainant requests the legal relief or action they seek from the authorities. Typically, for criminal cases, the complainant requests that a formal charge be filed against the respondent. For civil or administrative matters, the complainant may request an investigation or sanctions against the respondent.
- The prayer should be specific and clear about the remedy the complainant seeks.
Example:

“WHEREFORE, premises considered, I respectfully request that an appropriate criminal case for [specific crime] be filed against the respondent, and for such other relief as may be deemed just and equitable.”
Affirmation and Signature
- After the prayer, the complainant must affirm under oath that the contents of the affidavit are true and correct to the best of their knowledge and belief. This affirmation should be made before a notary public.
- The complainant then signs the affidavit, followed by the date and location of execution.
Example:

“I hereby certify that the foregoing statements are true and correct to the best of my knowledge and belief. I have executed this affidavit in good faith and in pursuit of justice. [Complainant’s Signature] [Date and Place of Execution]”
Notary Public
- The affidavit must be notarized by a licensed notary public. The notary will affix their signature, seal, and details of their commission to the document, affirming that the complainant appeared before them, was sworn in, and signed the affidavit voluntarily.

Common Mistakes to Avoid

Vagueness in Facts: The facts should be clear and detailed. Avoid generalizations or incomplete statements. Vague descriptions can weaken the case and result in the rejection of the complaint.
Failure to Provide Supporting Documents: Whenever possible, include any evidence that supports the complaint, such as photos, videos, or documents. This strengthens the veracity of the complaint and can be used for investigation purposes.
Incorrect Legal References: Be sure to correctly cite the laws or regulations that apply to the alleged offense. Failure to do so can undermine the complaint’s credibility.
Improper Format or Style: An affidavit should follow the proper legal format. A poorly structured affidavit can create confusion or make it difficult for authorities to understand the nature of the complaint.
Incomplete Signature and Notarization: Ensure that the affidavit is signed and notarized properly. Without a notarized signature, the affidavit may be considered invalid.

Filing the Affidavit of Complaint

Once the Affidavit of Complaint is drafted and notarized, it must be filed with the appropriate government agency. Typically, this is the Office of the City Prosecutor for criminal cases, but in certain instances, administrative complaints may be filed with specific regulatory agencies or local government units.

The complainant should submit the original copy of the affidavit, along with a certified true copy of any supporting evidence, to the relevant office. The office will then evaluate whether there is sufficient probable cause to proceed with the case. If the prosecutor finds probable cause, the case will be filed in court.

Conclusion

The drafting of an Affidavit of Complaint in the Philippines is a critical step in the legal process, particularly for the initiation of criminal and administrative proceedings. A well-written affidavit ensures that the complainant’s allegations are presented clearly and persuasively, increasing the chances of a successful investigation and prosecution. The complainant must take care to provide accurate facts, cite the correct legal provisions, and avoid common pitfalls to ensure that their complaint is taken seriously by the authorities.
