The commitment of any child, under any law of this state, to any state institution shall not relieve the parents or legal guardian of such child from responsibility for the support of the child. It is the duty of any court committing any child to any state institution or any private institution where such child is kept at the expense of the county or state, at the time of the commitment, to forthwith notify the district attorney, if a state expense, and the county attorney, if a county expense, of the name and address of such parents and such other information as may be adduced at any hearing of such case concerning the financial responsibility of the parents to care for such child. In order to obtain such information, any court committing any child, at the time of commitment or at any convenient time to be designated by the court, is authorized to require the attendance of the parents or legal guardian upon such court to be examined under oath concerning the property, possessions, and financial responsibility of such parents or legal guardian.
