Canon 955. §1 One who intends to transfer to others the celebration of Masses to be applied, is to transfer them as soon as possible to priests of his own choice, provided he is certain that they are of proven integrity. He must transfer the entire offering received, unless it is quite certain that an amount in excess of the diocesan offering was given as a personal gift. Moreover, it is his obligation to see to the celebration of the Masses until such time as he has received evidence that the obligation has been undertaken and the offering received.

§2 Unless it is established otherwise, the time within which Masses are to be celebrated begins from the day the priest who is to celebrate them receives them.

§3 Those who transfer to others Masses to be celebrated are without delay to record in a book both the Masses which they have accepted and those which they have passed on, noting also the offerings for these Masses.

§4 Each priest must accurately record the Masses which he has accepted to celebrate and those which he has in fact celebrated.

§1. Qui celebrationem Missarum applicandarum aliis committere intendat, earum celebrationem quam primum sacerdotibus sibi acceptis committat, dummodo ipsi constet eos esse omni exceptione maiores; integram stipem receptam transmittere debet, nisi certo constet excessum supra summam in dioecesi debitam datum esse intuitu personae; obligatione etiam tenetur Missarum celebrationem curandi, donec tum susceptae obligationis tum receptae stipis testimonium acceperit.

§2. Tempus intra quod Missae celebrandae sunt initium habet a die quo sacerdos easdem celebraturus recepit, nisi aliud constet.

§3. Qui aliis Missas celebrandas committunt, sine mora in librum referant tum Missas quas acceperunt, tum eas, quas aliis tradiderunt, notatis etiam earundem stipibus.

§4. Quilibet sacerdos accurate notare debet Missas quas celebrandas acceperit, quibusque satisfecerit.
