For Catholics, baptism must be done in a church by a priest (or deacon) with appropriate preparations and ceremony. If a baptism is not done thus, it is normally illicit (illegal). If a baptism is done in an emergency, such as danger of death, anyone can do it, but the minister is duty-bound to promptly report it to the priest responsible for the person who was baptized. That priest then has the duty to investigate its validity, and promptly record the baptism in the registers, and will usually offer the "supplied rites" which means a ceremony in church with the holy chrism, candle, and alb, because emergency baptisms are basically nothing but water and a hastily recited formula.
