Canon 520. §1 A juridical person may not be a parish priest. However, the diocesan Bishop, but not the diocesan Administrator, can, with the consent of the competent Superior, entrust a parish to a clerical religious institute or to a clerical society of apostolic life, even by establishing it in the church of the institute or society, subject however to the rule that one priest be the parish priest or, if the pastoral care is entrusted to several priests jointly, that there be a moderator as mentioned in can. 517§1.

§2 The entrustment of a parish, as in §1, may be either in perpetuity or for a specified time. In either case this is to be done by means of a written agreement made between the diocesan Bishop and the competent Superior of the institute or society. This agreement must expressly and accurately define, among other things, the work to be done, the persons to be assigned to it and the financial arrangements.

§1. Persona iuridica ne sit parochus; Episcopus autem dioecesanus, non vero Administrator dioecesanus, de consensu competentis Superioris, potest paroeciam committere instituto religioso clericali vel societati clericali vitae apostolicae, eam erigendo etiam in ecclesia instituti aut societatis, hac tamen lege ut unus presbyter sit paroeciae parochus, aut, si cura pastoralis pluribus in solidum committatur, moderator, de quo in can. 517, §1.

§2. Paroeciae commissio, de qua in §1, fieri potest sive in perpetuum sive ad certum praefinitum tempus; in utroque casu fiat mediante conventione scripta inter Episcopum dioecesanum et competentem Superiorem instituti vel societatis inita, qua inter alia expresse et accurate definiantur, quae ad opus explendum, ad personas eidem addicendas et ad res oeconomicas spectent.
