Canon 868. §1 For an infant to be baptised lawfully it is required:

1° that the parents, or at least one of them, or the person who lawfully holds their place, give their consent;

2° there must be a founded hope that the infant will be brought up in the Catholic religion subject to §3; if such hope is altogether lacking, the baptism is to be delayed according to the prescripts of particular law after the parents have been informed of the reason.
[revised wording according to m.p. De concordia inter Codices, 31.V.2016]

§2 An infant of catholic parents, indeed even of non-catholic parents, may in danger of death be baptised even if the parents are opposed to it.

§3. The child of non-Catholic Christians is lawfully baptized if the parents or at least one of them or the one who legitimately takes their place requests it and if it is impossible for them, physically or morally, to approach their own minister.
[new paragraph added by m.p. De concordia inter Codices, 31.V.2016]

§1. Ut infans licite baptizetur, oportet:

1° parentes, saltem eorum unus aut qui legitime eorundem locum tenet, consentiant;

2° spes habeatur fundata eum in religione catholica educatum iri, firma §3; quae si prorsus deficiat, baptismus secundum praescripta iuris particularis differatur, monitis de ratione parentibus.

§2. Infans parentum catholicorum, immo et non catholicorum, in periculo mortis licite baptizatur, etiam invitis parentibus.

§3. Infans christianorum non catholicorum licite baptizatur, si parentes aut unus saltem eorum aut is, qui legitime eorundem locum tenet, id petunt et si eis corporaliter aut moraliter impossibile sit accedere ad ministrum proprium.
