188.8.131.52.1 Priests and Deacons Visiting the Diocese of Lansing
1. The following norms apply to all secular and religious priests and deacons not incardinated in the Diocese of Lansing (including Eastern Catholic priests and deacons who possess bi-ritual faculties, and even those from other dioceses of the Province of Detroit). 
2. Before any non-incardinated priest or deacon can conduct any ecclesiastical ministry or pastoral service at any parish, institution or activity of the Diocese of Lansing or subject to the vigilance of its bishop, even for a single occasion, his background and suitability for ministry must be evaluated by the diocese in compliance with the Charter for the Protection of Children and Young People and any other applicable norms of law.
3. The priest or deacon must present from his particular church (e.g., diocese), personal prelature or religious community a document (no more than one year old) that certifies his suitability for ministry.
This is to be sent to the Office of the Bishop. The information in this document must include:
a. the name of the particular church (e.g., diocese), personal prelature or religious community of the priest or deacon (and if known, the proper office which provides documents of certification);
b. a correct mailing address, fax number or email contact;
c. the nature of the service or reason for ministering in this diocese so that any appropriate faculties or permissions of law may be granted;
d. whether permission and any faculties are requested for a single occasion, or a series of distinct occasions during a one year period, or for a period of time to include all occasions but not to exceed one year; and
e. the dates of arrival in the diocese and departure from the diocese.
4. However, the diocesan bishop may require additional confirmations of suitability, and the chancellor may also request them (e.g., such as when the priest or deacon currently serves outside the place of his incardination). The diocese may also require and consider additional information in order to evaluate the request. Additional documents may be required for extended stays to conform with Article 12 of the Charter. Special provision of law may apply in the case of priests and deacons from other countries.
5. After the chancellor verifies the suitability of the cleric, he will notify the pastor, administrator, or authorized agent about the permission and any particular faculties that are to be given to the cleric. The permission and any faculties may be given for a single occasion, or a series of distinct occasions during a one year period, or for a period of time to include all occasions but not to exceed one year.
6. All information about the visiting priest or deacon and the documents of suitability are to be preserved in the files of the chancellor.
 See cc. 265-266, 294; 368-371 regarding incardination and ecclesiastical circumscriptions. Also see c. 678§1.
