Nature of the Defect
A voidable marriage is a valid and binding marriage until it is annulled by final judgment. It produces marital status, property relations, legitimacy consequences, and duties between the spouses unless and until the court sets it aside.
The defect in a voidable marriage does not make the marriage nonexistent from the beginning. The law treats the marriage as capable of confirmation because the defect usually concerns consent, capacity to give an effective matrimonial consent, or a personal condition that the law allows the injured spouse to invoke within a fixed period.
The constitutional policy that marriage is an inviolable social institution explains the strict treatment of annulment. Private agreement, mutual regret, or a spouse's unilateral declaration cannot dissolve the bond; only a court judgment in a proper action may annul it.
All grounds for annulment must exist at the time of the celebration of marriage. A condition or event that arises only after marriage does not become a ground for annulment unless it proves that the statutory defect already existed when consent was given.
A voidable marriage differs from a void marriage because it may be ratified in specified cases, is subject to prescriptive periods, and may be assailed only by the persons authorized by law. Third persons cannot freely treat it as void, because the marital status exists until annulled.
Grounds for Annulment
The Family Code limits annulment to six statutory grounds. The enumeration is exclusive, so conduct that is unfair, immoral, disappointing, or incompatible with married life does not justify annulment unless it fits one of the recognized grounds.
| Ground | Essential idea | Effect of later cohabitation |
|---|---|---|
| Lack of required parental consent | One party was 18 or over but below 21 and married without the required consent of the parent, guardian, or person exercising substitute parental authority. | Freely living together as husband and wife after reaching 21 confirms the marriage. |
| Unsound mind | Either party was mentally incapable of understanding the nature, duties, and consequences of marriage at the time of celebration. | Freely living together after the afflicted party comes to reason confirms the marriage. |
| Fraud | Consent of the injured spouse was obtained by one of the specific fraudulent acts recognized by the Family Code. | Freely living together after full knowledge of the fraud confirms the marriage. |
| Force, intimidation, or undue influence | Consent was obtained by pressure that overcame the free will of the party whose consent was secured. | Freely living together after the coercive cause disappears or ceases confirms the marriage. |
| Physical incapacity to consummate | Either party was physically incapable of consummating the marriage with the other, and the incapacity continues and appears incurable. | Cohabitation does not operate as statutory ratification, but the action is subject to a fixed period. |
| Serious and apparently incurable sexually transmissible disease | Either party was afflicted at the time of marriage with a sexually transmissible disease that is serious and appears incurable. | Cohabitation does not operate as statutory ratification, but the action is subject to a fixed period. |
Lack of Required Parental Consent
A person who is 18 or over but below 21 has legal capacity to marry, but the Family Code requires parental consent for a validly unassailable marriage. The absence of that consent makes the marriage voidable, not void, because the party is old enough to possess legal capacity but the law still protects the family interest in the decision.
This ground is different from a marriage involving a party below 18. A person below the statutory minimum age lacks legal capacity to marry, so the defect belongs to the field of void marriages rather than annulment.
The relevant missing consent is the consent of the parent, guardian, or person exercising substitute parental authority. Lack of parental advice for persons in the older advisory bracket is not one of the grounds for annulment, although it may affect the issuance or timing of the marriage license under the statutory scheme.
The right to challenge the marriage is temporary. The under-21 spouse may annul only within the period fixed by law after reaching 21, and free cohabitation after reaching 21 confirms the marriage.
Unsound Mind
Unsound mind refers to a mental condition that prevents a party from understanding the nature of marriage and the obligations created by it. The decisive point is the mental condition at the moment of consent, not merely eccentric behavior, poor judgment, emotional immaturity, or later mental illness.
If the allegedly incapacitated party was in a lucid interval and understood the marriage when consent was given, the ground does not exist. Conversely, a later recovery does not erase the original defect unless the party, after coming to reason, freely cohabits with the other spouse as husband and wife.
The sane spouse may sue only if he or she had no knowledge of the other's unsound mind at the time of marriage. A spouse who knowingly married a person of unsound mind is not treated as the injured spouse for this purpose, although the law separately allows the insane spouse and certain representatives to protect the afflicted party's interest.
Fraud as a Ground
Fraud in annulment is narrower than fraud in ordinary contracts. Only the fraudulent acts enumerated by the Family Code vitiate matrimonial consent, and no other misrepresentation or concealment justifies annulment under this ground.
| Recognized fraud | Rule to remember |
|---|---|
| Non-disclosure of a previous conviction by final judgment of a crime involving moral turpitude | The conviction must be final, must exist before the marriage, and must involve moral turpitude. |
| Concealment by the wife of pregnancy by another man at the time of marriage | The pregnancy must already exist at the time of marriage and must be by a man other than the husband. |
| Concealment of a sexually transmissible disease existing at the time of marriage | For fraud, the concealment matters regardless of the nature of the disease; this is distinct from the separate ground requiring a serious and apparently incurable disease. |
| Concealment of drug addiction, habitual alcoholism, homosexuality, or lesbianism existing at the time of marriage | The condition must exist at the time of celebration and must be concealed from the injured spouse. |
The law expressly excludes other kinds of deceit from the concept of annulment fraud. Misrepresentation about character, health, rank, fortune, or chastity does not annul a marriage unless the deceit also falls within one of the specified statutory categories.
Fraud is personal to the injured spouse. The right is lost if, after discovering the truth, the injured spouse freely cohabits with the other as husband and wife, because the law treats that conduct as confirmation of the marriage despite full knowledge of the defect.
Force, Intimidation, and Undue Influence
This ground protects the requirement that matrimonial consent must be freely given. Force involves physical compulsion, intimidation involves a threat that creates a reasonable and serious fear, and undue influence involves improper domination that overcomes the will of the party giving consent.
The coercion must be the reason the party consented to the marriage. Pressure, family disappointment, social embarrassment, or persuasion is not enough unless the circumstances show that the person's free will was overcome.
The defect is curable after the coercive cause disappears. If the injured party, no longer under force, intimidation, or undue influence, freely lives with the other spouse as husband and wife, the marriage is confirmed.
Physical Incapacity to Consummate
Physical incapacity to consummate refers to incapacity to perform the sexual act that consummates marriage. It is not the same as sterility, infertility, inability to bear children, refusal to have intercourse, or mere absence of affection.
The incapacity must exist at the time of the marriage, must continue, and must appear incurable. Temporary, treatable, speculative, or unproven difficulty is insufficient because the statute requires a continuing and apparently incurable incapacity.
The incapacity may be absolute or relative. It is enough that the party is physically incapable of consummating the marriage with the other spouse, even if the condition is not shown in the abstract as to all persons.
The action belongs to the injured party and must be filed within the statutory period counted from the marriage. Unlike the consent-based grounds, this ground is not confirmed by later cohabitation under the ratification clauses, but delay beyond the statutory period bars the action.
Serious and Apparently Incurable Sexually Transmissible Disease
This ground requires a sexually transmissible disease existing at the time of marriage, serious in character, and apparently incurable. The seriousness and apparent incurability of the disease are part of the cause of action and must be established by competent proof.
The separate fraud ground should be kept distinct. Concealment of a sexually transmissible disease existing at the time of marriage may constitute fraud regardless of the disease's nature, while the independent disease ground requires seriousness and apparent incurability even if the issue is not framed as concealment.
A disease acquired only after the marriage is not a ground for annulment under this provision. Later discovery may be evidence of a pre-existing condition, but the operative fact must still be that the disease existed when the marriage was celebrated.
Who May File and When
Annulment is not available to anyone who is merely interested in the property or succession consequences of the marriage. The Family Code identifies the persons who may sue and fixes the period for each ground.
| Ground | Who may file | Period |
|---|---|---|
| Lack of required parental consent | The party who married without the required consent, or the parent, guardian, or person exercising substitute parental authority who did not give consent. | The party may sue within five years after reaching 21; the parent, guardian, or substitute parental authority may sue at any time before that party reaches 21. |
| Unsound mind | The sane spouse without knowledge of the insanity, a relative or guardian of the insane party, a person having legal charge of the insane party, or the insane spouse during a lucid interval or after regaining sanity. | The action by the sane spouse or representative must be brought before the death of either party; the insane spouse may sue during a lucid interval or after regaining sanity. |
| Fraud | The injured party whose consent was obtained by fraud. | Within five years after discovery of the fraud. |
| Force, intimidation, or undue influence | The injured party whose consent was obtained by coercion. | Within five years from the time the force, intimidation, or undue influence disappeared or ceased. |
| Physical incapacity to consummate | The injured party. | Within five years after the marriage. |
| Serious and apparently incurable sexually transmissible disease | The injured party. | Within five years after the marriage. |
The periods are part of the substantive protection of marital stability. Once the action prescribes, the voidable marriage remains valid and cannot be attacked on that ground.
Ratification by Free Cohabitation
Ratification applies only to the consent-based grounds of lack of parental consent, unsound mind, fraud, and force, intimidation, or undue influence. The confirming act is free cohabitation as husband and wife after the disabling circumstance has been removed or after the injured party has full knowledge of the defect.
For lack of parental consent, ratification occurs when the party freely cohabits with the other after reaching 21. For unsound mind, it occurs when the previously afflicted spouse freely cohabits after coming to reason. For fraud, it occurs when the injured spouse freely cohabits after discovering the fraud. For coercion, it occurs when the injured spouse freely cohabits after the pressure disappears or ceases.
Cohabitation while the defect still operates is not confirmation. Living together while still under intimidation, before discovering fraud, or before regaining reason does not show a free and informed election to preserve the marriage.
Judicial Action and State Participation
An annulment case is a direct action to change civil status. The court must receive evidence of the ground, the identity of the proper party, the timeliness of the action, and the absence of ratification where ratification is relevant.
Judgment cannot rest on stipulation of facts or confession of judgment. Because marriage concerns status and public interest, the State participates through the public prosecutor or proper government counsel to guard against collusion and fabricated or suppressed evidence.
During the pendency of the case, the court may regulate support, custody, visitation, and possession or use of the family dwelling in a manner consistent with the interests of the spouses and children. These provisional matters do not decide the validity of the marriage but preserve persons and property while the action is pending.
Effects of a Final Decree
A final judgment of annulment terminates the marital bond, but it does not erase every legal consequence that arose while the marriage was treated as valid. The Family Code supplies specific rules on children, property, donations, insurance, succession, and the capacity to remarry.
Children conceived or born before the judgment of annulment becomes final are legitimate. Their status is protected because the marriage was valid until annulled and because the law separately safeguards the rights of children from the defects of the parents' marital consent.
The property regime of the spouses must be liquidated, partitioned, and distributed as directed by the court. Creditors must be considered in the liquidation process, and the judgment should settle support, custody, and delivery of presumptive legitimes when required.
In the proper cases, the share of the spouse who contracted the marriage in bad faith in the net profits of the community or conjugal partnership is forfeited according to the statutory order. The bad-faith consequences may also affect donations by reason of marriage, insurance beneficiary designations, and succession rights.
The judgment of annulment, the partition and distribution of properties, and the delivery of presumptive legitimes must be recorded in the proper civil registry and registries of property. Without the required recording, the judgment and related instruments do not prejudice third persons.
Former spouses may remarry only after complying with the statutory requirements following annulment, including the required recording and property-related consequences. A later marriage entered into without the required compliance may itself be void.
Related Distinctions
Annulment is different from legal separation. Annulment dissolves the marital bond because a statutory defect existed at the time of marriage, while legal separation leaves the marriage bond intact and addresses wrongful conduct occurring within a valid marriage.
Annulment is also different from psychological incapacity. Psychological incapacity concerns a void marriage when the incapacity to assume essential marital obligations is juridical, grave, antecedent, and incurable in the sense recognized by law; voidable marriage under this topic concerns the specific statutory grounds for annulment.
Finally, annulment is different from divorce, which is not generally available under Philippine law for marriages governed by the Family Code. The remedy for a voidable marriage is a judicial decree of annulment based on one of the statutory grounds, filed by the proper party within the prescribed period.
