Other grounds for divorce may include alcohol or substance abuse and impotency, infertility or homosexuality (for heterosexual married couples) of the other party that was not discussed before the union. Strictly speaking, some jurisdictions may interpret the failure to disclose such conditions in advance as actual or constructive fraud that renders the marriage void, or at least voidable unless and until accepted by the other party once s/he learns of the condition(s), and thus serves as grounds for an annulment rather than for dissolution of a theretofore-valid marriage.
