My husband, an American citizen, had his first marriage civilly annulled in the superior court of his native state. (He had to get a decree of nullity from a Catholic tribunal also). I’m not sure how prevalent civil annulments are in the US, but my guess is that they are fairly rare. Here in Ireland, prior to the introduction of civil divorce, a civil annulment was the ONLY legal way to have a marriage ‘dissolved’ and it was almost impossible to attain. This resulted in people whose marriages had been declared invalid by a Catholic Church tribunal being unable legally to attempt marriage again. Those who did marry again with the blessing of the Church were technically regarded by the State as being in bigamous marriages though in practice a blind eye seems to have been turned by the authorities.
