In Philippine law, not every marriage that ends in court is considered void from the beginning. An [annulment applies to a voidable marriage](https://duranschulze.com/how-to-file-for-an-annulment-in-the-philippines/)—one that remains legally valid unless and until a court annuls it based strictly on a ground recognized by law. Under Article 45 of the Family Code (E.O. 209), [grounds for annulment](https://duranschulze.com/annulment-grounds-philippines/) include lack of parental consent, unsound mind or insanity, fraud, force or undue influence, physical incapacity, and sexually transmissible disease.  ## What Is Physical Incapacity as a Ground for Annulment? **Under Article 45(5) of the Family Code, a marriage may be annulled on the ground of physical incapacity existing at the time of the marriage.** To wit: *“(5) That either party was physically incapable of consummating the marriage with the other, and such incapacity continues and appears to be incurable; or”* As explained by the Supreme Court (SC), in *Alcazar v. Alcazar, G.R. No. 174451 (October 13, 2009)*, physical incapacity* (impotentia copulandi) *refers to lack of power to copulate or the permanent inability of either spouse to perform the complete act of sexual intercourse. Accordingly, such incapacity may be caused by physical or structural defects in the anatomy of the party, chronic illness, and inhibitions or fears arising from psychophysical conditions.  In *Sarao v. Guevarra, C.A. No. 4264 (1940)*, the Court held that the test of impotency is the ability to copulate, not the ability to procreate. In this case, the wife’s sterility, resulting from the removal of her uterus and ovaries, did not make her incapable of sexual intercourse. Since she was not physically incapable of copulation when the marriage was celebrated, her sterility did not constitute a ground for annulment. Sterility *(impotentia generandi), *even if permanent and incurable, does not qualify as physical incapacity and further does not render a marriage voidable. Likewise, even if a spouse deliberately conceals it prior to marriage, the Family Code does not recognize it as a form of fraud that vitiates marital consent.  ## Physical Incapacity Versus Psychological Incapacity Both physical and psychological incapacities are well discussed as grounds for dissolution of marriage but differ fundamentally in their nature, remedy, and required proof.  While physical incapacity or impotence under Article 45(5) renders a marriage voidable (valid until annulled), [psychological incapacity under Article 36](https://duranschulze.com/psychological-incapacity-declaration-nullity-marriage/) renders a marriage void *ab initio* (void from the beginning or as if it never legally existed). Based on recent jurisprudence, the latter refers to an enduring and incurable personality structure predating the marriage that prevents a spouse from performing the essential marital obligations.   In *Chi Ming Tsoi v. Court of Appeals, G.R. No. 119190 (January 16, 1997)*, the Supreme Court addressed the contention that a spouse’s refusal to have sexual relations may be attributable to physical rather than psychological causes. Accordingly, the Court held that a spouse fully capable of physical erection and penetration but harboring an utter, senseless refusal or aversion to engage in sexual intimacy with the partner suffers from psychological, rather than physical, incapacity.   [Image: Physical Incapacity (Impotence) as a Ground for Annulment] ## How to Prove Physical Incapacity in Annulment Cases **Pursuant to Article 47(5) of the Family Code, the injured spouse has five (5) years after the marriage to file an annulment on the ground of physical incapacity.** Proving physical incapacity to consummate marriage generally requires objective, expert evidence rather than self-serving claims.  Family courts primarily require expert testimony from a qualified physician who has physically examined the incapacitated spouse. The medical findings must establish *impotentia copulandi*—the anatomical structure or physical defect that prevents complete sexual intercourse—its existence at the time of marriage, and incurability.   In the landmark case of *Jimenez v. Cañizares, G.R. No. L-2790 (August 31, 1960),* the Supreme Court held that impotency, being an abnormal condition, should not be presumed, and that the presumption is in favor of potency. In this case, the injured husband alleged that his wife’s genitals were too small to allow penetration of a male organ for copulation. While the wife abstained from taking part in the proceedings and refused to be examined, the lone testimony of the husband was deemed insufficient to prove the ground for annulment.  While an injured spouse may request the court to issue an order for physical examination of the other spouse under Rule 28 of the Rules of Court, the Supreme Court,* in Jimenez v. Cañizares,* also clarified that a spouse’s refusal to undergo examination does not automatically trigger the legal presumption of suppressed evidence or guilt.  **Duran & Duran-Schulze Law (“DDS Law”)** is a family law firm in Metro Manila, Philippines, specializing in [annulments](https://duranschulze.com/annulment-of-marriage-assistance/), declarations of nullity of marriage, legal separation, and recognition of foreign divorces.
