Chapter 208 of the General Law, as appearing in the 2012 Official Edition, is hereby amended by inserting after section 31A the following section:-

31B.  If a parent makes a good faith allegation based on a reasonable belief supported by facts that the child is the victim of child abuse, child neglect, or the effects of domestic violence, and if that parent acts lawfully and in good faith in response to that reasonable  belief to protect the  child or seek treatment for the child, then that parent shall not be  deprived  of custody, visitation or contact with the child, or restricted in custody, visitation or contact, based solely on that belief or the reasonable actions taken based on that belief.  If an allegation that a child is abused is supported by a preponderance of the evidence, then the court shall consider such evidence of abuse in determining the visitation arrangement that is in the best interest of the child, and the court shall not place a child in the custody of a parent who presents a substantial risk of harm to that child, and shall state on the record how such findings were factored into the determination.
