One sponsor, male or female, is sufficient; but there may be two, one of each sex (canon 873).
§1 To be admitted to undertake the office of sponsor, a person must:
1° be appointed by the candidate for baptism, or by the parents or whoever stands in their place, or failing these, by the parish priest or the minister; to be appointed the person must be suitable for this role and have the intention of fulfilling it;
2° be not less than sixteen years of age, unless a different age has been stipulated by the diocesan bishop, or unless the parish priest or the minister considers that there is a just reason for an exception to be made;
3° be a Catholic who has been confirmed and has received the blessed Eucharist, and who lives a life of faith which befits the role to be undertaken;
4° not labor under a canonical penalty, whether imposed or declared;
5° not be either the father or the mother of the person to be baptised.
§2 A baptized person who belongs to a non-Catholic ecclesial community may be admitted only in company with a Catholic sponsor, and then simply as a witness to the baptism (canon 874).
