New Jersey Statutes Title 9. Children Juvenile and Domestic Relations Courts 9 § 6-8.46

a. In any hearing under this act, including an administrative hearing held in accordance with the “Administrative Procedure Act,” P.L.1968, c. 410 (C.52:14B-1 et seq.), (1) proof of the abuse or neglect of one child shall be admissible evidence on the issue of the abuse or neglect of any other child of, or the responsibility of, the parent or guardian and (2) proof of injuries sustained by a child or of the condition of a child of such a nature as would ordinarily not be sustained or exist except by reason of the acts or omissions of the parent or guardian shall be prima facie evidence that a child of, or who is the responsibility of such person is an abused or neglected child, and (3) any writing, record or photograph, whether in the form of an entry in a book or otherwise, made as a memorandum or record of any condition, act, transaction, occurrence or event relating to a child in an abuse or neglect proceeding of any hospital or any other public or private institution or agency shall be admissible in evidence in proof of that condition, act, transaction, occurrence or event, if the judge finds that it was made in the regular course of the business of any hospital or any other public or private institution or agency, and that it was in the regular course of such business to make it, at the time of the condition, act, transaction, occurrence or event, or within a reasonable time thereafter, shall be prima facie evidence of the facts contained in such certification.  A certification by someone other than the head of the hospital or agency shall be accompanied by a photocopy of a delegation of authority signed by both the head of the hospital or agency and by such other employees.  All other circumstances of the making of the memorandum, record or photograph, including lack of personal knowledge of the making, may be proved to affect its weight, but they shall not affect its admissibility and (4) previous statements made by the child relating to any allegations of abuse or neglect shall be admissible in evidence;  provided, however, that no such statement, if uncorroborated, shall be sufficient to make a fact finding of abuse or neglect.

b. In a fact-finding hearing (1) any determination that the child is an abused or neglected child must be based on a preponderance of the evidence and (2) only competent, material and relevant evidence may be admitted.

c. In a dispositional hearing and during all other stages of a proceeding under this act, only material and relevant evidence may be admitted.
