5.D.1 Conditional Baptism, Proof of Baptism and Validity of Non Catholic Baptism
1. The celebration of baptism administered conditionally is to take place according to the determination of the Bishop of Lansing in Rites for Conditional Baptism.  Each pastor is to maintain a copy of the document at the parish, and other staff are advised to obtain one. (It is available from the Office of Worship.)
2. Conditional baptism is to be carried out privately and not publicly (such as at a Eucharistic Liturgy or as one of many baptisms conferred at the same time). 
3. Before conditional baptism is conferred, the reason is to be explained to the parents of an infant or to the adult who is to be baptized. 
4. When a pastor or other minister of baptism has a reasonable doubt about the validity of baptism that is difficult to resolve, he is encouraged to consult the chancellor of the diocese.
