Can. 98

§1. A person who has reached majority has the full exercise of his or her rights.

§2. A minor, in the exercise of his or her rights, remains subject to the authority of parents or guardians except in those matters in which minors are exempted from their authority by divine law or canon law. In what pertains to the appointment of guardians and their authority, the prescripts of civil law are to be observed unless canon law provides otherwise or unless in certain cases the diocesan bishop, for a just cause, has decided to provide for the matter through the appointment of another guardian.
