Canon 366

1. The eparchial bishop is not to enroll an alien cleric to his

eparchy unless: (1) the needs or advantage of the eparchy require it; (2) he is convinced that the cleric has the aptitude

to carry out the ministry, especially if the cleric is coming

from another Church sui iuris; (3) he is convinced by a legitimate document that the cleric has obtained legitimate dismissal

from his eparchy; and he has obtained from the dismissing eparchial bishop, secretly if appropriate, suitable testimonials concerning the background and morals of the cleric; (4) the cleric

has declared in writing that he is devoting himself to service of

the new eparchy according to the norm of the law. 2. The eparchial bishop is to inform the previous eparchial bishop about the

completed enrollment of the cleric into his eparchy as soon as

possible.
