Canon 268. §1 A cleric who has lawfully moved from his own particular Church to another is, by virtue of the law itself, incardinated in that latter Church after five years, if he has declared this intention in writing to both the diocesan Bishop of the host diocese and his own diocesan Bishop, and neither of the two Bishops has indicated opposition in writing within four months of receiving the cleric’s written request.

§2 By perpetual or definitive admission into an institute of consecrated life or a society of apostolic life, a cleric who in accordance with can. 266 is incardinated in that institute or society, is excardinated from his own particular Church.

§1. Clericus qui a propria Ecclesia particulari in aliam legitime transmigraverit, huic Ecclesiae particulari, transacto quinquennio, ipso iure incardinatur, si talem voluntatem in scriptis manifestaverit tum Episcopo dioecesano Ecclesiae hospitis tum Episcopo dioecesano proprio, neque horum alteruter ipsi contrariam scripto mentem intra quattuor menses a receptis litteris significaverit.

§2. Per admissionem perpetuam aut definitivam in institutum vitae consecratae aut in societatem vitae apostolicae, clericus qui, ad normam can. 266, §2, eidem instituto aut societati incardinatur, a propria Ecclesia particulari excardinatur.
