Canon 230. §1 Lay persons who possess the age and qualifications established by decree of the conference of bishops can be admitted on a stable basis through the prescribed liturgical rite to the ministries of lector and acolyte. Nevertheless, the conferral of these ministries does not grant them the right to obtain support or remuneration from the Church.
[revised wording according to m.p. Spiritus Domini, 10.I.2021]

§2 Lay people can receive a temporary assignment to the role of lector in liturgical actions. Likewise, all lay people can exercise the roles of commentator, cantor or other such, in accordance with the law.
[NB see Authentic Interpretation of canon 230 §2, 11.VII.1992]

§3 Where the needs of the Church require and ministers are not available, lay people, even though they are not lectors or acolytes, can supply certain of their functions, that is, exercise the ministry of the word, preside over liturgical prayers, confer baptism and distribute Holy Communion, in accordance with the provisions of the law.
[NB see Authentic Interpretation of canon 910 §2, 1.VI.1988]

§1. Laici, qui aetate dotibusque pollent Episcoporum conferentiae decreto statutis, per ritum liturgicum praescriptum ad ministeria lectoris et acolythi stabiliter assumi possunt; quae tamen ministeriorum collatio eisdem ius non confert ad sustentationem remunerationemve ab Ecclesia praestandam.

§2. Laici ex temporanea deputatione in actionibus liturgicis munus lectoris implere possunt; item omnes laici muneribus commentatoris, cantoris aliisve ad normam iuris fungi possunt.

§3. Ubi Ecclesiae necessitas id suadeat, deficientibus ministris, possunt etiam laici, etsi non sint lectores vel acolythi, quaedam eorundem officia supplere, videlicet ministerium verbi exercere, precibus liturgicis praeesse, baptismum conferre atque sacram Communionem distribuere, iuxta iuris praescriptas.
