For ordination to the
diaconate as a member of the diocesan clergy (i.e. at the service of a
diocese), authority to grant dimissorial letters is vested in the bishop of the diocese in to which the candidate will be incardinated. For ordination to the priesthood, this authority is vested in the bishop of the diocese in which the person to be ordained is
incardinated as a deacon. An
apostolic administrator and, provided they have the consent of certain groups, certain other ecclesiastics provisionally in charge of a diocese can also issue such letters. For ordination to diaconate or priesthood of a member of a
religious institute, the major superior of the institute gives the letters, if the person to be ordained is a permanently
professed member of the institute; all other members must obtain their dimissorial letters in the same way as the secular clergy do. In a mixed congregation of men (both priests and brothers) only a priest can be elected to be the major superior (superior general) and only a cleric that is superior general can issue a dimissorial letter. ==Requirements for granting dimissorial letters==
