Adultery Case File Contents

Disclaimer: This article is provided for general informational and educational purposes only. It is not legal advice. For any specific questions or concerns regarding adultery cases in the Philippines, it is best to consult a licensed attorney.


1. Introduction

In the Philippines, adultery is considered a criminal offense under the Revised Penal Code (RPC). The crime specifically applies to a married woman who engages in consensual sexual intercourse with a man who is not her husband, and to the man who has carnal knowledge of her. Given the sensitive and personal nature of adultery cases, preparing and reviewing the case file requires precise documentation, proper legal procedure, and close attention to detail.

This article explains the contents of an adultery case file in the Philippine context—namely, what documents, evidence, and records are typically included, how they are compiled, and their relevance in prosecuting an adultery case.


2. Legal Basis for Adultery in Philippine Law

  1. Revised Penal Code (Article 333):

    • Defines adultery as committed by any married woman who shall have sexual intercourse with a man not her husband and by the man who has carnal knowledge of her.
    • Punishes both the wife and the paramour (the man involved) if the offense is proven.
  2. Who May File the Complaint:

    • Under Article 344 of the Revised Penal Code, only the offended spouse (i.e., the husband of the woman) can initiate the criminal complaint for adultery.
    • This requirement aims to protect the privacy of the family; no one else can file the complaint.
  3. Prescription Period:

    • The right to file an adultery case prescribes (expires) five (5) years from the date the offense is discovered by the offended spouse.
  4. Other Relevant Legal Provisions:

    • Jurisdiction: Typically, adultery cases fall under the jurisdiction of the appropriate trial court (often the Municipal Trial Court in Cities [MTCC] or Regional Trial Court [RTC], depending on the circumstances).
    • Venue: Usually, the criminal complaint must be filed in the place where the adulterous act was allegedly committed.

3. Typical Contents of an Adultery Case File

An adultery case file in the Philippines generally comprises several key documents, records, and pieces of evidence. Though every case is unique, these are the common elements:

  1. Complaint-Affidavit

    • The complaint-affidavit is the foundational document. It is executed by the offended husband and sets out the specific allegations of adultery, including:
      • Identities of the parties (the wife and the alleged paramour).
      • Date(s) and place(s) of the alleged adulterous act(s).
      • Factual narrative of how and when the husband discovered the relationship.
      • An explicit request for the filing of the appropriate criminal charge.
  2. Supporting Affidavits (Witness Statements)

    • If there are other individuals who can testify to relevant circumstances—such as neighbors, friends, relatives, or anyone who directly witnessed or has personal knowledge about the alleged affair—they may execute supporting affidavits.
    • These affidavits help corroborate the husband’s complaint and provide additional factual details.
  3. Marriage Certificate

    • A certified true copy of the marriage certificate is indispensable. Since adultery can only be committed by a married woman (and the man who cohabits with or has carnal knowledge of her), evidence of a valid marriage is a central element of the offense.
  4. Evidence of the Adulterous Act

    • Photographs or Videos: If available and lawfully obtained, these can be powerful pieces of evidence, though issues of privacy and authenticity may arise.
    • Correspondence and Messages: Exchanges of text messages, social media chats, emails, or letters that tend to prove an intimate relationship.
    • Hotel or Lodging Receipts: Documents indicating that the wife and alleged paramour stayed together or reserved a room.
    • Witness Testimony: Testimony from individuals who observed the parties entering or leaving the same room or location.
  5. Additional Documentary Evidence

    • Proof of Cohabitation (if alleged): Utility bills or rental agreements indicating both parties lived in the same address (though cohabitation is more often a part of concubinage charges against a husband, it can still be relevant for proving repeated encounters or a sustained relationship).
    • Medical or Physical Evidence: In rare cases, a medical examination or other forms of forensic evidence can become relevant if the nature of the sexual relationship is in question.
  6. Prosecutor’s Documents and Resolutions

    • During the preliminary investigation, the prosecutor’s office reviews the complaint and supporting affidavits. Any resolution (whether to dismiss the complaint or to file the case in court) is included in the case file.
    • The prosecutor’s resolution will summarize the evidence, address its sufficiency, and recommend whether charges should be filed.
  7. Court Pleadings and Process

    • Once the prosecutor files the Information (formal charge) in court, the Information document becomes part of the court record.
    • Other pleadings such as motions to quash, motions for bail, or counter-affidavits submitted during or after the inquest or preliminary investigation stages may also appear.
  8. Police or Investigative Reports (if applicable)

    • If the local police or National Bureau of Investigation (NBI) were involved in gathering evidence, any official reports or certifications they produce will be part of the file.
    • These may detail surveillance findings, retrieval of electronic data, or other investigative actions.
  9. Transcript of Stenographic Notes (TSN)

    • Should the case proceed to trial, the transcripts of all hearings and testimonies will form part of the records of the case.
    • These transcripts capture the sworn statements of witnesses, cross-examination, and rulings by the judge.
  10. Judicial Orders and Decisions

  • As the case moves through the court, all orders (e.g., scheduling orders, bail orders, orders for further submission of evidence) are kept in the official file.
  • Ultimately, the decision or final judgment—whether acquittal or conviction—is included in the record.

4. Building a Strong Case: Key Considerations

  1. Strict Proof of Sexual Intercourse

    • Under Philippine law, adultery requires proof of actual sexual intercourse between the married woman and a man who is not her husband.
    • Opportunity alone (like being seen together in a private space) may not suffice unless proven by direct or compelling circumstantial evidence.
  2. Limitations of Circumstantial Evidence

    • Because proving the act of sexual intercourse can be challenging, cases often rely on strong circumstantial evidence, such as:
      • Consistent eyewitness accounts.
      • Confirmed presence together in private quarters.
      • Text messages or emails about sexual encounters.
    • The courts scrutinize such evidence rigorously to guard against unfounded accusations.
  3. Relevance of Privacy Laws

    • Photographs, videos, or intercepted communications can raise potential issues under privacy laws (e.g., the Anti-Photo and Video Voyeurism Act, the Data Privacy Act).
    • Illegally obtained evidence can be excluded or challenged in court.
  4. Exclusivity of the Remedy

    • Under Article 344 of the RPC, the offended spouse must file the complaint. No other person can do so, and the offended spouse must not have consented to or pardoned the adulterous act.
    • Once the case is filed, the husband cannot simultaneously file a concubinage case against the wife’s alleged paramour—concubinage typically applies to husbands, while adultery applies to wives.
  5. Effect of Pardon or Condonation

    • If the husband pardoned the wife’s act, expressly or impliedly, before filing the complaint, it can extinguish the criminal liability and result in dismissal of the complaint.

5. Typical Flow of the Adultery Case

  1. Filing of the Complaint-Affidavit:

    • Offended spouse executes and files the complaint-affidavit with the Prosecutor’s Office, attaching the required evidence.
  2. Preliminary Investigation:

    • The prosecutor summons the respondents (the wife and the alleged paramour) to submit counter-affidavits.
    • Parties may submit additional evidence.
    • The prosecutor determines if there is probable cause.
  3. Resolution and Filing of Information:

    • If probable cause is found, the prosecutor issues a resolution recommending the filing of an Information.
    • The Information is then filed in the appropriate trial court.
  4. Arraignment and Pre-Trial:

    • The court reads the charge to the accused, who enter pleas of guilty or not guilty.
    • Pre-trial conference sets the parameters for trial: issues to be tried, evidence to be presented, and possible stipulations.
  5. Trial Proper:

    • The prosecution presents its evidence first, including witnesses, documents, and other exhibits.
    • The defense then presents its evidence.
    • Cross-examinations and re-direct examinations follow.
  6. Decision:

    • After both sides rest, the court issues a judgment: conviction or acquittal.
    • A convicted party may appeal, subject to the rules of court.

6. Possible Outcomes and Penalties

  1. Criminal Penalties:

    • Adultery is punishable by prisión correccional in its medium and maximum periods. This translates to imprisonment generally ranging from two years, four months, and one day (2 years, 4 months, 1 day) to six (6) years.
    • Both the wife and the paramour face the same penalty if found guilty.
  2. Civil Implications:

    • Adultery convictions can impact related matters such as legal separation, annulment, custody, and property disputes. Although these are separate legal proceedings, the criminal case outcome might influence evidence or negotiations.

7. Practical Tips and Reminders

  1. Gather Solid Evidence Early:

    • Because of the strict requirement to prove actual sexual intercourse (or very strong circumstantial evidence of it), thorough evidence collection is crucial.
  2. Avoid Illegal Means of Evidence Gathering:

    • Using illegal surveillance, hacking, or unauthorized recording can lead to evidence being deemed inadmissible.
    • It can also expose the complainant or their agents to potential legal liabilities.
  3. Seek Legal Counsel:

    • An attorney experienced in family law and criminal litigation can guide the offended spouse through the complexities of prosecuting an adultery case.
    • Legal counsel can also help explore other remedies (e.g., civil suits, protection orders, or alternative dispute resolution) if appropriate.
  4. Consider Psychological and Family Implications:

    • Adultery charges are highly personal and can place enormous strain on family relationships and children, if any.
    • Parties may also explore marriage counseling or mediation before resorting to legal action—although that is a personal decision based on one’s circumstances.

8. Conclusion

An adultery case file in the Philippines contains a comprehensive record of evidence, affidavits, legal pleadings, and court documents that together aim to establish the commission of the crime under Article 333 of the Revised Penal Code. Proper documentation—from the complaint-affidavit, affidavits of witnesses, and marriage certificates, to all relevant pieces of evidence such as photographs, messages, hotel receipts, and other corroborating material—provides the foundation for the prosecution.

However, prosecuting an adultery case can be highly sensitive, time-consuming, and emotionally taxing. The strict legal requirement of proving sexual intercourse beyond reasonable doubt makes it imperative for the offended spouse to gather credible, admissible evidence and follow lawful procedures. In all cases, seeking professional legal guidance is strongly recommended to safeguard rights and ensure due process.
