In one request for baptism, there is a discrepancy on the date of marriage of the parents on the marriage contract and the birth certificate of the child to be baptized. What can we do about this?

Before baptism, it is important to know whether or not the parents of the child to be baptized are legally married. This will have an effect on the surname of the child that should appear on the baptismal certificate. The date of marriage is a useful reference, but is not a necessary information. However, for verification purposes and to determine the truthfulness of the parents, you may ask them to explain the discrepancy in information.

Can the birthplace also be indicated on the baptismal certificate?

In the format used by the Catholic Church for baptismal certificates, the birthplace is not a mandatory information. However, if this information is necessary, the parents may request that this information be stated on the baptismal certificate.
