Where the interests of the sole legal administrator or, as the case may be, of both legal administrators are in opposition to those of the minor, the latter shall request the appointment of an ad hoc administrator by the guardianship judge. Failing diligence on the part of the legal administrators, the judge may make this appointment at the request of the public prosecutor, the minor himself or of his own motion.
When the interests of one of the two legal administrators are in opposition to those of the minor, the guardianship judge may authorise the other legal administrator to represent the child for one or more specific acts.
