Canon 1303. §1 In law the term pious foundation comprises:

1° autonomous pious foundations, that is, aggregates of things destined for the purposes described in can. 114 §2, and established as juridical persons by the competent ecclesiastical authority.

2° non-autonomous pious foundations, that is, temporal goods given in any way to a public juridical person and carrying with them a long-term obligation, such period to be determined by particular law. The obligation is for the juridical person, from the annual income, to celebrate Masses, or to perform other determined ecclesiastical functions, or in some other way to fulfil the purposes mentioned in can. 114 §2.

§2 If the goods of a non-autonomous pious foundation are entrusted to a juridical person subject to the diocesan Bishop, they are, on the expiry of the time, to be sent to the fund mentioned in can. 1274 §1, unless some other intention was expressly manifested by the donor. Otherwise, the goods fall to the juridical person itself.

§1. Nomine piarum fundationum in iure veniunt:

1° piae fundationes autonomae, scilicet universitates rerum ad fines de quibus in can. 114, §2 destinatae et a competenti auctoritate ecclesiastica in personam iuridicam erectae;

2° piae fundationes non autonomae, scilicet bona temporalia alicui personae iuridicae publicae quoquo modo data cum onere in diuturnum tempus, iure particulari determinandum, ex reditibus annuis Missas celebrandi aliasque praefinitas functiones ecclesiasticas peragendi, aut fines de quibus in can. 114, §2 aliter persequendi.

§2. Bona piae fundationis non autonomae, si concredita fuerint personae iuridicae Episcopo dioecesano subiectae, expleto tempore, ad institutum de quo in can. 1274, §1 destinari debent, nisi alia fuerit fundatoris voluntas expresse manifestata; secus ipsi personae iuridicae cedunt.
