California Code, Family Code - FAM § 3100

(a) In making an order pursuant to Chapter 4 (commencing with Section 3080), the court shall grant reasonable visitation rights to a parent when it is shown that the visitation would be in the best interest of the child, as defined in Section 3011, and consistent with Section 3020. In the discretion of the court, reasonable visitation rights may be granted to any other person having an interest in the welfare of the child.

(b) If a protective order, as defined in Section 6218, has been directed to a parent, the court shall consider whether the best interest of the child requires that any visitation by that parent be limited to situations in which a third person, specified by the court, is present, or whether visitation shall be suspended, limited, or denied. The court shall include in its deliberations a consideration of the nature of the acts from which the parent was enjoined and the period of time that has elapsed since that order. A parent may submit to the court the name of a person that the parent deems suitable to be present during visitation.

(c) If visitation is ordered in a case in which domestic violence is alleged and an emergency protective order, protective order, or other restraining order has been issued, the visitation order shall specify the time, day, place, and manner of transfer of the child, so as to limit the child's exposure to potential domestic conflict or violence and to ensure the safety of all family members. If a criminal protective order has been issued pursuant to Section 136.2 of the Penal Code, the visitation order shall make reference to, and, unless there is an emergency protective order that has precedence in enforcement pursuant to paragraph (1) of subdivision (c) of Section 136.2 of the Penal Code or a no-contact order, as described in Section 6320, acknowledge the precedence of enforcement of, an appropriate criminal protective order.

(d) If the court finds a party is staying in a place designated as a shelter for victims of domestic violence or other confidential location, the court's order for time, day, place, and manner of transfer of the child for visitation shall be designed to prevent disclosure of the location of the shelter or other confidential location.
