On transfer to another religious institute (Can. 633-636)
Canon 632
A religious cannot transfer to another religious [institute], even a stricter one, or to a monastery of its own right without the authority of the Apostolic See.
Canon 633
§ 1. One transferring to another religious [institute] must perform the novitiate; during which his vows remain, [but] special rights and obligations that he had in the former religious [institute] remain suspended, and he is bound by the obligation of complying with the Superiors of the new religious [institute] and their Master of novices also in virtue of the vow of obedience.
§ 2. If he does not make profession in the religious [institute] to which he is transferring, he is bound to return to the first religious [institute], unless in the meantime temporary vows expired. § 3. One transferring to another monastery of the same Order does not undergo novitiate or make a new profession.
Canon 634
One professed solemnly or professed by simple, perpetual vows, if he transfers to another religious [institute] with solemn vows or simple, perpetual vows, is either admitted, after novitiate and the completion of temporary profession mentioned in Canon 574, to solemn profession or to simple, perpetual profession, or returns to the prior religious [institute]; it is, nevertheless, the right of the Superior to prolong this probation, but not more than one year from the completion of novitiate.
Canon 635
One transferring to another monastery of the same religious [institute], from the day of transfer, or to another religious [institute], from having given the new profession:
1.° Loses all the rights and obligations of the prior religious [institute] or monastery and takes up the rights and duties of the other;
2.° The goods remain with the religious [institute] or monastery from which, that had already been acquired by him by reason of the religious [institute]; for what pertains to the dowry and the income and other personal goods if the religious had any, the prescription of Canon 551, § 2, is observed; as for the rest, the new religious [institute] has the right for the time of novitiate to a just repayment if this is in order according to the norm of Canon 570, § 1.
Canon 636
The solemnity of vows in him who legitimately pronounced simple vows in a religious Congregation according to the above canons is extinguished, unless something else is expressly provided in the apostolic indult.
