(a)

1. (1) No person shall be granted physical or legal custody of, or unsupervised visitation with, a child if the person is required to be registered as a sex offender under Section 290 of the Penal Code where the victim was a minor, or if the person has been convicted under Section 273a, 273d, or 647.6 of the Penal Code, unless the court finds that there is no significant risk to the child and states its reasons in writing or on the record. The child may not be placed in a home in which that person resides, nor permitted to have unsupervised visitation with that person, unless the court states the reasons for its findings in writing or on the record.
2. (2) No person shall be granted physical or legal custody of, or unsupervised visitation with, a child if anyone residing in the person’s household is required, as a result of a felony conviction in which the victim was a minor, to register as a sex offender under Section 290 of the Penal Code, unless the court finds there is no significant risk to the child and states its reasons in writing or on the record. The child may not be placed in a home in which that person resides, nor permitted to have unsupervised visitation with that person, unless the court states the reasons for its findings in writing or on the record.
3. (3) The fact that a child is permitted unsupervised contact with a person who is required, as a result of a felony conviction in which the victim was a minor, to be registered as a sex offender under Section 290 of the Penal Code, shall be prima facie evidence that the child is at significant risk. When making a determination regarding significant risk to the child, the prima facie evidence shall constitute a presumption affecting the burden of producing evidence. However, this presumption shall not apply if there are factors mitigating against its application, including whether the party seeking custody or visitation is also required, as the result of a felony conviction in which the victim was a minor, to register as a sex offender under Section 290 of the Penal Code.

(c) No person shall be granted custody of, or unsupervised visitation with, a child if the person has been convicted of murder in the first degree, as defined in Section 189 of the Penal Code, and the victim of the murder was the other parent of the child who is the subject of the order, unless the court finds that there is no risk to the child’s health, safety, and welfare, and states the reasons for its finding in writing or on the record. In making its finding, the court may consider, among other things, the following:

1. (1) The wishes of the child, if the child is of sufficient age and capacity to reason so as to form an intelligent preference.
2. (2) Credible evidence that the convicted parent was a victim of abuse, as defined in Section 6203, committed by the deceased parent. That evidence may include, but is not limited to, written reports by law enforcement agencies, child protective services or other social welfare agencies, courts, medical facilities, or other public agencies or private nonprofit organizations providing services to victims of domestic abuse.

3. (3) Testimony of an expert witness, qualified under Section 1107 of the Evidence Code, that the convicted parent experiences intimate partner battering.

   Unless and until a custody or visitation order is issued pursuant to this subdivision, no person shall permit or cause the child to visit or remain in the custody of the convicted parent without the consent of the child’s custodian or legal guardian.
