excardination

The absolute and perpetual release of a cleric from the diocese in which he has heretofore been incardinated. Excardination is not effective unless the cleric receives absolute and perpetual letters affiliating him with another diocese, vicariate, or prefecture Apostolic. This release must, for validity, be signed by the Ordinary of the place. A cleric is likewise excardinated if he receives the written permission of his Ordinary to accept a residential benefice in another diocese, or written permission to leave the diocese perpetually, having received such a residential benefice in another diocese. A religious who makes perpetual profession is likewise excardinated from his diocese.
