§ 773. Petition for transfer. Any institution, society or agency in
which a person was placed under section seven hundred fifty-six of this
article may petition to the court which made the order of placement for
transfer of that person to a society or agency, governed or controlled
by persons of the same religious faith or persuasion as that of the
child, where practicable, or, if not practicable, to some other suitable
institution, or to some other suitable institution on the ground that

(a) the presence of such person is seriously detrimental to the
welfare of the applicant institution, society, agency or other persons
in its care, or

(b) after placement by the court, such person was released on parole
or probation from such institution, society or agency and a term or
condition of the release was willfully violated. The petition shall be
verified by an officer of the applicant institution, society or agency
and shall specify the act or acts bringing the person within this
section.
