Physical incapacity to consummate the marriage — commonly called impotence — is a ground for annulment when it existed at the time of the marriage, appears to be incurable, and continues. It is distinct from sterility (inability to have children), which is not itself a ground. The incapacity must be permanent and, in practice, is proven by medical evidence. A related ground is where either party is afflicted with a serious and apparently incurable sexually transmissible disease existing at the time of marriage. Like other annulment grounds, there are prescriptive periods and requirements, so the specifics of the case matter.
Among the grounds for annulment (as distinct from nullity) is one that is frequently misunderstood: physical incapacity to consummate the marriage, often called impotence.
Impotence Is Not Sterility
An important distinction: impotence is the inability to perform the sexual act — to consummate the marriage. This is different from sterility, which is the inability to procreate (have children). Sterility alone is not a ground for annulment; a couple who cannot have children but can consummate the marriage does not have this ground.
The Requisites
For impotence to be a ground, it generally must be:
- Existing at the time of the marriage — not something that arose only afterward;
- Permanent / apparently incurable — a temporary or curable condition does not suffice; and
- Continuing — it persists.
The party seeking annulment must generally not have known of the incapacity, and must not be the one who is incapacitated using their own condition as a ground in bad faith.
How It Is Proven
Because it is a physical condition, impotence is typically established through medical evidence and examination. Courts scrutinize the claim carefully. There is a well-known rule of evidence in this area (sometimes called the “triennial cohabitation” presumption) under which, if the spouses have lived together for a period without consummation, a presumption may arise about the impotence of one of them — but this is a matter of proof, not an automatic ground.
The Related STD Ground
A related annulment ground exists where either party, at the time of marriage, was afflicted with a serious and apparently incurable sexually transmissible disease. Like impotence, the condition must exist at the time of the marriage and meet the seriousness/incurability requirement.
Prescription
As with other annulment grounds, there are prescriptive periods within which the action must be filed. This makes timing important — do not assume the ground remains available indefinitely.
Practical Takeaways
- Impotence (inability to consummate) is a ground; sterility (inability to have children) is not;
- It must have existed at the time of marriage, be permanent/incurable, and continue;
- Expect the need for medical evidence, and mind the prescriptive period.
Frequently Asked Questions
Is impotence a ground for annulment? Yes. Physical incapacity to consummate the marriage, existing at the time of marriage, apparently incurable, and continuing, is a ground for annulment, distinct from grounds that make a marriage void.
Is being unable to have children a ground for annulment? No. Sterility (inability to procreate) is not itself a ground. The ground is impotence, which is the inability to perform the sexual act and consummate the marriage.
How is impotence proven? It is typically established through medical evidence and examination. Courts scrutinize the claim, and there is an evidentiary presumption that may arise from prolonged cohabitation without consummation.
Is there a deadline to file? Yes. As with other annulment grounds, there are prescriptive periods within which the action must be filed, so timing is important.
