§1. A person who has accepted goods in trust for pious causes either through an act inter vivos or by a last will and testament must inform the ordinary of the trust and indicate to him all its movable and immovable goods with the obligations attached to them. If the donor has expressly and entirely prohibited this, however, the person is not to accept the trust.
§2. The ordinary must demand that goods held in trust are safeguarded and also exercise vigilance for the execution of the pious will according to the norm of can. 1301.
§3. When goods held in trust have been entrusted to a member of a religious institute or society of apostolic life and if the goods have also been designated for some place or diocese or for the assistance of their inhabitants or pious causes, the ordinary mentioned in §§1 and 2 is the local ordinary; otherwise, it is the major superior in a clerical institute of pontifical right and in clerical societies of apostolic life of pontifical right or the proper ordinary of the member in other religious institutes.
