Grounds for Annulment in the Philippines Under Article 45: Fraud, Impotence, Disease and Insanity

Not every flawed marriage in the Philippines is void from the start. Some marriages are valid until a court annuls them — and Philippine law recognizes only six specific causes for that kind of annulment, listed in Article 45 of the Family Code. If your situation does not fit one of these six causes, or the time limit to raise it has already passed, annulment on that basis is generally no longer available, no matter how compelling the underlying facts feel. This guide walks through each of the six grounds, what “fraud” legally means under the closely linked Article 46, who is allowed to file for each ground and by when under Article 47, and how these voidable-marriage grounds differ from a void marriage or from psychological incapacity under Article 36.

Article 45 of the Family Code of the Philippines: annulment grounds

Article 45 is the core Family Code provision for voidable marriages that may be annulled. It is different from Article 36 psychological incapacity and from provisions governing marriages that are void from the beginning. Use the six statutory grounds below as the starting point, then match the facts and evidence to the specific ground relied on.

Direct Answer

Article 45 of the Family Code allows a marriage to be annulled only for one of six causes that existed at the time the marriage was celebrated: (1) the marrying party was 18 to below 21 years old and married without parental consent; (2) either party was of unsound mind; (3) consent was obtained through fraud, as fraud is narrowly defined in Article 46 (see what kinds of fraud qualify under Article 46); (4) consent was obtained through force, intimidation, or undue influence; (5) either party was physically incapable of consummating the marriage, and that incapacity appears incurable; or (6) either party had a sexually transmissible disease that was serious and appears incurable. Each ground has its own prescriptive period under Article 47 — generally five years, measured differently depending on the ground — and several grounds are extinguished (“ratified”) if the couple freely continued living together as spouses after the impediment was known or had ceased. These are exhaustive causes: a marriage cannot be annulled for a reason outside this list, however unfair the underlying situation may be. A marriage annulled under Article 45 is different from one declared void from the outset (for example, under Article 36 for psychological incapacity, or Article 35 for a marriage below the legal age) — a voidable marriage is valid and produces legal effects unless and until a court annuls it.

Evidence and action

RuleFamily Code, Articles 45–47 (binding law). Fraud counts only in Article 46’s four cases: a concealed conviction for a crime of moral turpitude, pregnancy by another man, a sexually transmissible disease, or drug addiction, habitual alcoholism or homosexuality. Anaya v. Palaroan treats that list as exclusive.
ExceptionGrounds 1–4 are lost if the injured party freely cohabits as a spouse after turning 21, regaining reason, learning of the fraud or being free of the force. Incapacity and serious disease have no such cure. Article 36 and other void marriages need a separate nullity case.
EvidenceRecords that fix key dates (birth certificate for age, when the fraud was discovered, when the force ended), lawfully obtained medical records for incapacity or disease, communications and witness information may help establish the ground.
TimingArticle 47 generally allows five years from turning 21, discovering the fraud, the force ending, or the wedding (incapacity and disease). A parent or guardian must sue before the party turns 21. Unsound mind: any time before either party dies.
Next stepMatch your facts to one ground, check its deadline and whether cohabitation has ratified it, then consult a family lawyer or the Public Attorney’s Office. Treat any safety or abuse issue separately through protective remedies.

Choose Your Route

  • Possible Article 45 case: match facts to one statutory ground and its deadline.
  • Psychological incapacity or void marriage issue: use the separate nullity analysis rather than forcing it into annulment.
  • Safety or abuse issue: consider immediate protective remedies separately from marital-status litigation.

Decision Snapshot

  • Applies to: Anyone assessing whether their specific facts fit one of the Family Code’s six grounds for annulling a voidable marriage.
  • The six grounds: Lack of parental consent (age 18–20), unsound mind, fraud (as defined in Article 46), force/intimidation/undue influence, incurable physical incapacity to consummate, and a serious incurable sexually transmissible disease.
  • Fraud is narrowly defined: Article 46 lists only four specific kinds of concealment that count as fraud — general deceit about character, health, rank, fortune, or chastity does not qualify.
  • Time limits apply: Each ground has its own prescriptive period under Article 47, generally five years, measured from a different starting point depending on the ground.
  • First action: Identify which single ground your specific facts actually fit, confirm you are still within its prescriptive period, and consult a lawyer or the Public Attorney’s Office to assess the evidence needed.

Key Takeaways

  • Article 45 lists exactly six grounds for annulling a voidable marriage — no other reason, however sympathetic, is legally sufficient on its own.
  • A voidable marriage is valid unless and until a court annuls it; this is legally different from a void marriage, which never had legal effect at all.
  • “Fraud” for annulment purposes is limited to the four specific circumstances in Article 46 — the Supreme Court has held this list to be exclusive and restrictive, not illustrative.
  • Several grounds are cured (“ratified”) if the couple freely cohabited as spouses after the party regained free will, discovered the fraud, or the force/intimidation ceased.
  • Prescriptive periods differ by ground: generally five years, but measured from different starting points (discovery of fraud, cessation of force, the marriage date itself, or the injured party turning 21).
  • Physical incapacity to consummate and a serious sexually transmissible disease are the two grounds without a cohabitation-based cure, and both must be shown to be incurable.
  • Article 45 grounds are distinct from Article 36 psychological incapacity, which makes a marriage void from the beginning rather than merely voidable — the two are commonly confused but have different legal consequences and different rules on who may sue and when.

Who This Applies To

This guide applies to anyone trying to determine whether their marriage can be annulled under Article 45 — as distinct from seeking a declaration that a marriage was void from the start. It applies whether the marriage was solemnized recently or years ago, since several of these grounds (most notably unsound mind) have no fixed filing deadline tied to the marriage date itself. It does not apply to couples seeking legal separation, which does not dissolve the marriage bond at all, or to couples pursuing a declaration of nullity of a void marriage — for example, a marriage void because one spouse was already married to someone else, covered in FamilyCode.ph’s guide to bigamy and void marriages — which involves a different set of grounds — Articles 35 and 36, along with the prohibited-relative categories in Articles 37 and 38 — and different procedural consequences.

The Six Grounds for Annulment Under Article 45

Under Family Code Article 45, an annulment ground must have existed when the marriage was celebrated, and the first four grounds can be lost through ratification if the parties freely continue cohabiting as spouses after the impediment is known, discovered, or has ceased. The table shows which grounds have that rule:

Ground What it requires Cured by later cohabitation?
1. Lack of parental consent A party was 18 years old but below 21 at the time of marriage, and married without the consent of the parent, guardian, or person exercising substitute parental authority Yes — if the party, after turning 21, freely cohabited with the other as spouses
2. Unsound mind Either party was of unsound mind at the time of the marriage Yes — if the party of unsound mind, after coming to reason, freely cohabited with the other as husband and wife
3. Fraud Consent was obtained through fraud, as fraud is defined exclusively in Article 46 Yes — if the injured party, with full knowledge of the facts constituting the fraud, freely cohabited with the other as spouses
4. Force, intimidation, or undue influence Consent was obtained through force, intimidation, or undue influence Yes — if, after it disappeared or ceased, the injured party freely cohabited with the other as spouses
5. Physical incapacity (impotence) Either party was physically incapable of consummating the marriage with the other, and the incapacity continues and appears to be incurable No cohabitation-based cure specified
6. Serious sexually transmissible disease Either party was afflicted with a sexually transmissible disease, found to be serious and appearing to be incurable No cohabitation-based cure specified

1. Lack of parental consent (age 18 to below 21)

Philippine law sets the general minimum age to marry at 18; a marriage where either party was below 18 is void from the outset under Article 35 and Republic Act No. 11596 (the law prohibiting child marriage), not merely voidable. Article 45(1) covers a narrower, older-age situation: a party who was 18 or older but still below 21 married without the consent of a parent, guardian, or the person then exercising substitute parental authority over them. The defect here is the missing consent, not the marriage’s basic validity — which is why it is voidable rather than void, and why it disappears if the party, once they turn 21, chooses to keep living with their spouse as husband and wife. For a closer look at how the consent requirement itself works, exactly who may file and by when, and how the ground is lost through ratification, see our guide on whether lack of parental consent (ages 18 to 21) is a ground for annulment.

2. Unsound mind

If either spouse was of unsound mind at the time the marriage was celebrated, the marriage is voidable. This ground is separate from Article 36 psychological incapacity — unsound mind under Article 45(2) concerns mental capacity to give valid consent to marriage at the ceremony itself, not a psychological condition that renders someone incapable of fulfilling the essential marital obligations over time. The impediment is cured if, after the previously unsound party comes to reason, the couple freely continues living together as spouses. For a closer look at this specific ground — including who may file, why it has no fixed five-year deadline unlike most other Article 45 grounds, and how it differs in practice from psychological incapacity — see our guide on whether unsound mind is a valid ground for annulment.

3. Fraud

Fraud is a ground only when it fits the narrow definition in Article 46 — covered in detail in the next section. General deception about a person’s character, wealth, social standing, or past relationships does not qualify, however material it felt to the decision to marry.

4. Force, intimidation, or undue influence

A marriage entered into because a party’s consent was obtained through force, intimidation, or undue influence is voidable. As with the other grounds above, this is cured if, after the force, intimidation, or undue influence has disappeared or ceased, the injured party freely continues cohabiting with the other spouse. For a closer look at this specific ground — including what legally counts as force, intimidation, or undue influence, the five-year filing deadline, and how continued cohabitation can ratify the marriage — see our guide on whether force, intimidation, or undue influence is grounds for annulment.

5. Physical incapacity to consummate the marriage (impotence)

If either party was physically incapable of consummating the marriage with the other, and that incapacity continues and appears to be incurable, the marriage may be annulled on this ground. The incapacity must exist at the time of the marriage and must genuinely appear incurable — a temporary or treatable condition does not qualify. Unlike the first four grounds, Article 45 does not provide a cohabitation-based cure for this one. For a closer look at this specific ground — including how it differs from sterility, the demanding evidentiary standard Philippine courts apply, and the five-year filing deadline — see our guide on whether physical incapacity (impotence) is a valid ground for annulment.

6. Serious and incurable sexually transmissible disease

If either party was afflicted, at the time of the marriage, with a sexually transmissible disease found to be serious and appearing to be incurable, the marriage is voidable on that basis. As with physical incapacity, there is no cohabitation-based cure for this ground under Article 45. For a closer look at this specific ground — including how it differs from the separate fraud-based ground for concealing an STD under Article 46(3), and what a related law says about HIV testing and confidentiality — see our guide on whether a serious, incurable sexually transmissible disease is grounds for annulment.

What Counts as Fraud Under Article 46

Under the Family Code of the Philippines, Article 46 fraud is an annulment ground only when consent was obtained through one of four exclusive forms of concealment or non-disclosure existing at the time of marriage; ordinary deceit about character, health, rank, fortune, or chastity does not qualify:

  1. Non-disclosure of a previous conviction by final judgment of the other party of a crime involving moral turpitude;
  2. Concealment by the wife of a pregnancy by a man other than her husband;
  3. Concealment of a sexually transmissible disease, regardless of its nature, existing at the time of the marriage; or
  4. Concealment of drug addiction, habitual alcoholism, or homosexuality or lesbianism existing at the time of the marriage.

Article 46 closes with an express limitation: “No other misrepresentation or deceit as to character, health, rank, fortune or chastity shall constitute such fraud as will give grounds for action for the annulment of marriage.” In Anaya v. Palaroan (G.R. No. L-27930, Nov. 26, 1970), the Supreme Court confirmed that this enumeration is exclusive and restrictive — the Court rejected an attempt to treat non-disclosure of a premarital relationship as fraud, precisely because it falls outside the four listed circumstances.

Concealment of pregnancy by another man is a recurring, fact-sensitive claim. In Buccat v. Buccat (G.R. No. 47101, Apr. 25, 1941), the Supreme Court denied an annulment petition based on this ground where the wife was already in an advanced, visibly obvious state of pregnancy at the time of the wedding — the Court found it implausible that the husband had not noticed, and required clear and convincing proof, which was absent. This illustrates that a concealment claim can fail on its facts even where the underlying circumstance (pregnancy by another man) is one Article 46 recognizes.

More recently, in Salva-Roldan v. Roldan (G.R. No. 268109, Mar. 3, 2025), the Supreme Court granted an annulment petition where the respondent had concealed his homosexuality before the marriage — a ground expressly listed in Article 46(4). The Court found that the totality of the evidence, including the respondent’s own admission, established fraudulent concealment by a preponderance of the evidence. The case confirms that this specific, narrowly defined ground continues to be actively applied by Philippine courts.

Who May File, and By When

Under Family Code Article 47, who may file an annulment case and when depends on the Article 45 ground. Filing after the applicable period generally forecloses that ground, while standing may belong to the injured party, a parent or guardian, or specified persons connected to an unsound-mind claim.

Ground Who may generally file Prescriptive period
Lack of parental consent The party who married without the required consent, or the parent/guardian who did not give it The party: within five years after reaching age 21. The parent or guardian: generally before the party reaches 21.
Unsound mind The sane spouse who had no knowledge of the other’s condition before the marriage, a relative, guardian, or person with legal charge of the party of unsound mind — or the party of unsound mind personally, upon coming to reason At any time before the death of either party
Fraud The injured party Within five years after discovery of the fraud
Force, intimidation, or undue influence The injured party Within five years from the time the force, intimidation, or undue influence disappeared or ceased
Physical incapacity (impotence) The injured party Within five years after the marriage
Serious sexually transmissible disease The injured party Within five years after the marriage

Because standing to sue and the exact starting point of each period can turn on case-specific facts — for example, precisely when a fraud was “discovered” — confirm both points with a lawyer or the Public Attorney’s Office before assuming a given ground is still available to you.

How This Differs From Void Marriages and Article 36

Under the Family Code of the Philippines, Article 45 annulment concerns a voidable marriage that remains valid until a court annuls it, whereas a void marriage has no legal effect from the beginning. Article 36 psychological incapacity belongs to the void-marriage category, not the Article 45 annulment category. Psychological incapacity in particular is frequently confused with the Article 45 grounds because both can involve a spouse’s mental or psychological state — but Article 36 addresses a spouse’s incapacity, existing at the time of the marriage though possibly manifesting later, to comply with the essential marital obligations, and it renders the marriage void from the beginning rather than merely voidable. The two grounds have different elements, different evidentiary standards, and different prescriptive rules (an action to declare a marriage void does not prescribe), so identifying which category your situation actually falls into is a necessary first step before deciding which kind of petition to file.

Common Misunderstandings

  • “Any lie my spouse told me before we married counts as fraud.” Not under Article 46. Only the four specific circumstances it lists qualify; the Supreme Court has confirmed this list is exclusive, not illustrative.
  • “If my spouse turned out to have a mental illness, that’s automatically ‘unsound mind’ under Article 45.” The unsound-mind ground concerns capacity to give valid marital consent at the time of the ceremony itself — it is a separate legal question from Article 36 psychological incapacity, which concerns capacity to fulfill marital obligations and voids the marriage rather than making it merely voidable.
  • “I can file for annulment on this ground whenever I’m ready.” Each Article 45 ground has its own prescriptive period under Article 47 — several are as short as five years from a specific triggering event. Missing that period can foreclose the ground entirely, regardless of how strong the underlying facts are.
  • “We kept living together after I found out, so I can still use it as a ground whenever I want.” For several grounds, continuing to freely cohabit as spouses after discovering the fraud, after the force ceased, or after regaining reason legally ratifies the marriage and extinguishes that specific ground.
  • “A serious illness discovered years into the marriage is grounds for annulment under Article 45(6).” The disease must have existed, and been serious and apparently incurable, at the time of the marriage itself — a condition that developed afterward does not fit this ground.

Practical Checklist

  1. Identify which single ground in Article 45 actually matches your specific facts — the six grounds are exhaustive, and general unhappiness or incompatibility is not one of them.
  2. If you believe fraud applies, check your facts against Article 46’s four specific circumstances before assuming general deception qualifies.
  3. Confirm the prescriptive period that applies to your ground under Article 47, and whether you are still within it.
  4. Consider whether continued cohabitation after discovering the impediment may have already ratified the marriage for that specific ground.
  5. Gather documentary and testimonial evidence relevant to your specific ground — for example, medical records for physical incapacity or disease, or evidence of the timeline for a fraud-discovery date.
  6. Confirm whether you might qualify for free legal representation through the Public Attorney’s Office based on its income test.
  7. Consult a Philippine family-law lawyer to assess whether your specific facts, and the timing, realistically support a petition before you file.

Frequently Asked Questions

Can I annul my marriage simply because I no longer love my spouse or we are incompatible?

No. Article 45 lists six specific grounds, and incompatibility or falling out of love is not among them. Your situation must fit one of the six grounds — or a separate ground for a void marriage, such as Article 36 — to qualify.

Is hiding a premarital relationship or past sexual history grounds for annulment?

No. The Supreme Court in Anaya v. Palaroan confirmed that Article 46’s fraud grounds are exclusive; general non-disclosure about a person’s past relationships or character does not qualify as fraud for annulment purposes.

What is the difference between annulment under Article 45 and a declaration of nullity under Article 36?

An Article 45 annulment applies to a voidable marriage — one that is valid unless and until a court annuls it, for one of six specific grounds that existed at the time of the wedding. A declaration of nullity under Article 36 applies to a marriage that is void from the very beginning because a spouse was psychologically incapacitated to comply with essential marital obligations. The two involve different elements, different evidence, and different rules on time limits.

Does living together after discovering my spouse’s fraud or after force stopped mean I lose my right to annul?

It can. Several Article 45 grounds — lack of parental consent, unsound mind, fraud, and force/intimidation/undue influence — are legally cured if the injured party freely continues cohabiting with the other spouse after the impediment was known, discovered, or ceased. Physical incapacity and serious disease do not have this cohabitation-based cure.

Is concealment of homosexuality still a valid fraud ground today?

Yes. Article 46(4) expressly lists concealment of homosexuality or lesbianism existing at the time of the marriage as one of the four fraud circumstances, and the Supreme Court applied this ground as recently as Salva-Roldan v. Roldan in March 2025.

How long do I have to file if I discover the fraud years after the wedding?

Under Article 47, an action based on fraud must generally be filed within five years after discovery of the fraud — not five years from the wedding date itself. Confirm the applicable starting point for your specific facts with a lawyer, since this can be fact-sensitive.
