Canon 271. §1 Except for a grave need of his own particular Church, a Bishop is not to refuse clerics seeking permission to move whom he knows to be prepared and considers suitable to exercise the ministry in regions which suffer from a grave shortage of clergy. He is to ensure, however, that the rights and duties of these clerics are determined by written agreement with the diocesan Bishop of the place to which they wish to move.

§2 A Bishop can give permission to his clerics to move to another particular Church for a specified time. Such permission can be renewed several times, but in such a way that the clerics remain incardinated in their own particular Church, and on returning there enjoy all the rights which they would have had if they had ministered there.

§3 A cleric who lawfully moves to another particular Church while remaining incardinated in his own, may for a just reason be recalled by his own Bishop, provided the agreements entered into with the other Bishop are honoured and natural equity is observed. Under the same conditions, the Bishop of the other particular Church can for a just reason refuse the cleric permission to reside further in his territory.

§1. Extra casum verae necessitatis Ecclesiae particularis propriae, Episcopus dioecesanus ne deneget licentiam transmigrandi clericis, quos paratos sciat atque aptos aestimet qui regiones petant gravi cleri inopia laborantes, ibidem sacrum ministerium peracturi; prospiciat vero ut per conventionem scriptam cum Episcopo dioecesano loci, quem petunt, iura et officia eorundem clericorum stabiliantur.

§2. Episcopus dioecesanus licentiam ad aliam Ecclesiam particularem transmigrandi concedere potest suis clericis ad tempus praefinitum, etiam pluries renovandum, ita tamen ut iidem clerici propriae Ecclesiae particulari incardinati maneant, atque in eandem redeuntes omnibus gaudeant iuribus, quae haberent si in ea sacro ministerio addicti fuissent.

§3. Clericus qui legitime in aliam Ecclesiam particularem transierit propriae Ecclesiae manens incardinatus, a proprio Episcopo dioecesano iusta de causa revocari potest, dummodo serventur conventiones cum altero Episcopo initae atque naturalis aequitas; pariter, iisdem condicionibus servatis, Episcopus dioecesanus alterius Ecclesiae particularis iusta de causa poterit eidem clerico licentiam ulterioris commorationis in suo territorio denegare.
