Quick answer

You cannot personally “deport” a foreigner for having an affair with your partner. Deportation is a government immigration proceeding, and an affair by itself does not automatically require removal from the Philippines.

Legal action may nevertheless be possible when the facts satisfy a specific law:

If you are legally married, the foreign affair partner may be criminally liable for adultery or concubinage, but only if every statutory element is proved.
A civil damages claim may be possible if the affair partner knowingly and wrongfully interfered with your family relations and caused provable injury. Damages are not automatic.
Remedies against your unfaithful spouse may include legal separation, civil damages, or—when its separate elements exist—a case under the Anti-Violence Against Women and Their Children Act.
You may submit a verified deportation complaint to the Bureau of Immigration (BI), but you must allege an actual immigration-law ground. BI, not the complainant, decides whether proceedings and deportation are warranted.

The foreigner’s nationality neither excuses conduct committed in the Philippines nor creates a special offense. Philippine penal laws generally apply to everyone who lives or stays here, subject to international law and treaties. See Civil Code, Article 14.

Which remedy may apply?

Situation	Possible remedy	Important limitation
Your wife had sexual intercourse with a foreign man who knew she was married	Adultery complaint	The offended husband must generally charge both living participants
Your husband kept or cohabited with a foreign mistress, or had sex with her under scandalous circumstances	Concubinage complaint	A private or isolated affair does not automatically prove the statutory modes
You and your unfaithful partner are not married	Other civil or protective remedies, depending on the conduct	Adultery, concubinage, and legal separation do not apply to unmarried couples
A woman suffers psychological violence from her own husband or intimate partner’s infidelity	Possible Republic Act No. 9262 case or protection order	The law does not punish infidelity alone; its criminal elements must be established
The foreigner violated immigration law or is convicted under circumstances covered by the Immigration Act	Verified BI complaint	A private report does not itself cancel a visa or produce deportation
The affair partner deliberately disrupted a marriage and caused measurable harm	Possible civil damages action	Bad faith, wrongful interference, injury, and causation remain fact-dependent

When the foreign affair partner may face a criminal case

Adultery

Under Article 333 of the Revised Penal Code, adultery is committed when:

A married woman has sexual intercourse with a man who is not her husband; and
The man knows that she is married.

The man receives the same statutory penalty as the married woman. Each proven act of sexual intercourse may constitute a separate offense. A romantic attachment, suspicious messages, kissing, or an admission of “having an affair” does not necessarily prove the legally required sexual intercourse, although properly authenticated circumstantial evidence may be considered.

The prescribed penalty is prisión correccional in its medium and maximum periods—generally two years, four months and one day to six years—subject to sentencing rules. A lower penalty applies when the wife committed the offense while unjustifiably abandoned by her husband. The governing text appears in the Revised Penal Code, Article 333.

Concubinage

Article 334 applies when a married husband:

Keeps a mistress in the conjugal dwelling;
Has sexual intercourse with a woman who is not his wife under scandalous circumstances; or
Cohabits with her in another place.

For the woman to be criminally liable, she must know that the man is married. The Supreme Court restated these elements in Singgit v. People.

The husband faces prisión correccional in its minimum and medium periods—generally six months and one day to four years and two months. The mistress faces destierro, which restricts her from entering designated places or areas rather than placing her in ordinary imprisonment.

Compared with adultery, concubinage requires more than proof that a married husband had a private sexual encounter. The prosecution must establish one of the three modes stated in Article 334.

Only the offended spouse may initiate these cases

Adultery and concubinage are exceptional “private crimes.” Under Article 344 and Rule 110 of the Rules of Criminal Procedure:

The complaint must be filed by the offended spouse.
If both alleged participants are alive, the offended spouse generally cannot prosecute only one of them.
Prior consent to the relationship or pardon of the offenders bars prosecution.
A foreign divorce, judicial recognition of that divorce, declaration of nullity, or other document affecting the marriage may determine whether the complainant remains the “offended spouse.”

This rule is summarized in the Supreme Court’s discussion of Article 344.

A complaint should therefore be reviewed before filing, especially if there has been reconciliation, written forgiveness, a foreign divorce, or a long period of tolerated cohabitation.

Does being a foreigner change criminal liability?

Not ordinarily. A foreign national may be prosecuted for a Philippine offense committed within Philippine territory. Diplomatic immunity, treaty protections, and the territorial location of the conduct can create exceptions.

If the alleged sexual conduct occurred entirely abroad, a Philippine adultery or concubinage prosecution faces a serious territorial-jurisdiction problem. The Revised Penal Code applies extraterritorially only in limited situations, and ordinary adultery or concubinage is not among the usual Article 2 exceptions. Identify precisely where each alleged act occurred before filing.

The foreigner’s role also matters. The adultery and concubinage provisions are written in specific, gendered terms. A person does not become liable merely because they are the romantic third party; they must occupy the role and satisfy the knowledge and conduct requirements stated in the applicable article.

Can you sue the foreigner for damages?

Possibly, but there is no automatic damages award for emotional pain caused by an affair.

Articles 19, 20, 21, and 26 of the Civil Code recognize liability for abuse of rights, unlawful or willfully injurious conduct, and acts that meddle with or disturb another person’s private life or family relations. Article 21, for example, requires a willful act causing loss or injury in a manner contrary to morals, good customs, or public policy. Article 26 expressly covers interference with private life or family relations. See the official Civil Code text.

A viable complaint normally needs specific allegations and evidence showing:

The foreigner knew about the marriage or protected family relationship;
Their conduct went beyond innocent association or unwitting involvement;
The conduct wrongfully interfered with the family relationship;
You suffered an identifiable injury; and
The wrongful conduct caused that injury.

Possible relief may include actual damages supported by receipts or records, moral damages where legally justified, exemplary damages in qualifying cases, and injunctive or preventive relief. The court determines both liability and amount. Filing merely to punish, embarrass, or pressure someone—without evidence of a recognized legal wrong—can expose the complainant to costs and counterclaims.

Article 345 of the Revised Penal Code also permits the adulterer or concubine to be ordered, in the criminal case or a separate civil proceeding, to indemnify the offended spouse for resulting damage.

Remedies against the unfaithful spouse or partner

Legal separation

Sexual infidelity is a ground for legal separation under Article 55(8) of the Family Code. The petition must be filed within five years from the occurrence of the cause. Condonation, consent, connivance, mutual fault, collusion, or prescription can defeat the petition.

Legal separation permits the spouses to live separately and produces property and succession consequences, but it does not dissolve the marriage bond. See Family Code, Articles 55–63.

Nullity based on psychological incapacity

Infidelity alone does not make a marriage void and is not, by itself, a ground for annulment. It may support a petition under Article 36 only when evidence establishes that the infidelity manifests a grave psychological incapacity to perform essential marital obligations and that the incapacity existed when the marriage was celebrated. The Supreme Court explains this distinction in Clavecilla v. Clavecilla.

Psychological violence under Republic Act No. 9262

For a woman victim, marital infidelity may form part of psychological violence by her husband or by a man with whom she has or had a dating or sexual relationship. What the law punishes is not infidelity standing alone, but psychological violence that causes mental or emotional anguish, public ridicule, or humiliation, with the required criminal intent and other elements.

The Supreme Court has emphasized that the complainant’s anguish is a distinct element and that liability depends on the totality of the evidence. See Acharon v. People, AAA v. BBB, and the Court’s 2024 ruling on marital infidelity as psychological violence.

Republic Act No. 9262 ordinarily applies to the woman’s own husband, former husband, intimate partner, former intimate partner, or person with whom she has a common child—not to an outsider merely because that outsider is the mistress or paramour. Separate liability may arise if the outsider personally commits threats, stalking, harassment, violence, or another offense.

The official statute provides protection orders, support services, and a ten-year prescriptive period for acts under Section 5(i). See Republic Act No. 9262.

Can an affair lead to deportation?

It can contribute to a deportation case in limited circumstances, but deportation is neither automatic nor a private punishment.

Section 37(a)(3) of the Philippine Immigration Act covers an alien who is convicted in the Philippines and sentenced to at least one year for a crime involving moral turpitude committed within five years after entry, or who is convicted and sentenced more than once after entry under the statutory conditions. Philippine jurisprudence has classified adultery and concubinage as crimes involving moral turpitude.

Whether this ground applies depends on matters such as:

A final Philippine conviction;
The particular sentence imposed;
The date of the offense relative to the foreigner’s entry;
Whether there is more than one qualifying conviction;
The statutory time limit for commencing deportation proceedings; and
Any recommendation against deportation made by the sentencing court, as permitted by Section 37(b).

Other independent grounds may exist—for example, unlawful entry, misrepresentation, overstaying, or violating the conditions of a nonimmigrant visa. The controlling provisions are in Commonwealth Act No. 613, Section 37.

The President also has constitutional executive authority to deport aliens subject to due process under the Administrative Code of 1987, Book III, Chapter 3. In ordinary BI proceedings, the foreigner must be informed of the specific ground and given the hearing required by law.

Marriage to a Filipino, parenthood of a Filipino child, or possession of a valid visa does not create absolute immunity from deportation. Conversely, an accusation of immorality or marital interference does not authorize immediate removal.

How to report a legitimate immigration ground

Under the BI Omnibus Rules of Procedure, a private citizen may commence a deportation action through a verified complaint alleging grounds provided by law. The complaint must be under oath and should state:

The complainant’s full name and postal address;
The respondent foreigner’s name, known aliases, and known or last address;
Concise ultimate facts establishing the legal deportation ground; and
Supporting documents.

The rules direct filing with the Office of the Commissioner through the Central Receiving Unit, in two copies plus a copy for each respondent. Confirm the current filing location, fees, and documentary requirements with the BI Legal Division before submission because administrative procedures may be amended. See the official BI Omnibus Rules of Procedure and BI contact directory.

A verified complaint begins an evaluation; it is not a deportation order. Knowingly false statements or fabricated evidence can create criminal and civil exposure. Do not threaten to report someone to immigration as leverage for money, property, custody, reconciliation, or departure.

Evidence to preserve lawfully

Before confronting anyone or posting accusations online, preserve evidence in its original form:

Your PSA marriage certificate and any foreign marriage, divorce, or recognition records;
A dated chronology of events, including the precise locations of alleged conduct;
Original messages, emails, photographs, public posts, and files with available metadata;
Full-page screenshots showing usernames, dates, URLs, and surrounding context;
Names and contact details of witnesses with personal knowledge;
Lawfully obtained lease records, travel records, receipts, photographs, or public representations of cohabitation;
Evidence that the affair partner knew of the marriage;
Medical, counseling, employment, or financial records documenting claimed injury;
Threats, harassment, abandonment, withholding of support, or public humiliation relevant to a possible Republic Act No. 9262 case; and
The foreigner’s correct legal identity, nationality, known address, and immigration details, if lawfully available.

Keep untouched copies and secure backups. Do not crop away context or edit filenames and timestamps. Electronic evidence must be authenticated; being a screenshot does not make it self-proving. The Electronic Commerce Act places the burden of proving authenticity on the party presenting the electronic record.

Do not hack accounts, guess passwords, impersonate another person, install spyware, trespass, or secretly intercept private communications. Republic Act No. 4200 generally prohibits secretly recording or intercepting a private communication without authorization from all parties. See the Anti-Wiretapping Law.

Important deadlines

Do not assume that an old affair can be litigated indefinitely:

Legal separation must be filed within five years from the occurrence of the cause.
Civil actions based on injury to rights generally prescribe in four years from accrual, although the legal basis and proper reckoning date can change the period.
Crimes punishable by correctional penalties generally prescribe in ten years under Articles 90 and 91 of the Revised Penal Code. Discovery, interruption by proceedings, absence from the Philippines, and separate acts can affect computation.
Psychological violence under Section 5(i) of Republic Act No. 9262 prescribes in ten years.
Immigration grounds have their own conditions and time limits; Section 37(b), for example, restricts when deportation may be effected under several statutory clauses.

Have counsel calculate the deadline from the actual documents and dates. A mistaken starting date can permanently defeat an otherwise valid case.

Common mistakes to avoid

Treating rumors, emotional messages, or photographs together as conclusive proof of sexual intercourse.
Assuming that every affair by a husband constitutes concubinage.
Filing adultery or concubinage against only the foreigner while the other alleged participant is alive.
Assuming that foreign nationality alone makes someone “undesirable” or deportable.
Confusing legal separation, annulment, declaration of nullity, and deportation.
Publicly naming, shaming, or doxxing the alleged participants before evidence is tested.
Obtaining evidence through hacking, spyware, trespass, or secret recordings.
Editing screenshots, deleting original messages, or losing the device containing the evidence.
Filing a BI complaint as retaliation without identifying a statutory immigration ground.
Waiting until witnesses disappear, records are deleted, or a prescriptive period is close to expiring.

When legal help is urgent

Seek immediate assistance if there are threats, assault, stalking, coercive control, sexual violence, risk to a child, destruction of evidence, planned flight from the country, or an approaching filing deadline. Contact the police or local Women and Children Protection Desk when safety is at risk. A woman experiencing violence may also seek assistance from her Barangay VAW Desk and ask about a barangay, temporary, or permanent protection order.

For case assessment, consult a Philippine family-law or criminal-law practitioner. Qualified applicants may approach the Public Attorney’s Office. The Integrated Bar of the Philippines also maintains legal-aid contact information.

Frequently asked questions

Can I have the foreigner arrested simply by showing BI screenshots of the affair?

No. Screenshots may support an investigation, but arrest, prosecution, visa action, and deportation each require a legal basis and the applicable process. An affair allegation alone is not an arrest or deportation order.

Can I file adultery or concubinage if we are only live-in partners?

No. Those offenses require a valid and subsisting marriage involving the allegedly unfaithful spouse. Other remedies may apply if there was violence, harassment, fraud, property loss, or another independent legal wrong.

Can I charge only the foreign affair partner because I have forgiven my spouse?

Generally no. If both alleged participants are alive, Article 344 requires inclusion of both. Pardon or consent can also bar the prosecution.

Is an emotional or online affair enough?

Usually not for adultery, which requires sexual intercourse, or for concubinage, which requires one of Article 334’s specified modes. Online conduct may still be relevant to psychological violence, harassment, civil injury, or proof of a broader relationship, depending on its content and effects.

Will a criminal conviction automatically result in deportation?

Not necessarily. Section 37(a)(3) contains sentence, timing, and conviction requirements, and deportation still follows the legally required immigration process. The sentencing court may also make the recommendation allowed by Section 37(b).

Can I recover money for embarrassment and emotional distress?

Possibly, but you must establish a recognized cause of action and prove the wrongful conduct, injury, and causal connection. Courts do not award damages merely because betrayal was painful.

Does proof of infidelity automatically make the marriage void?

No. Sexual infidelity is expressly a ground for legal separation. It supports nullity under Article 36 only when it is proven to be a manifestation of psychological incapacity meeting that article’s separate requirements.

What if the affair happened outside the Philippines?

Territorial jurisdiction, the place where any resulting psychological violence was experienced, the parties’ citizenship, and foreign family-law documents may all matter. Obtain advice before filing because Philippine criminal jurisdiction does not automatically cover private sexual conduct occurring wholly abroad.

This article provides general Philippine legal information, not legal advice or a prediction of any case’s outcome.
