Child Custody

California Family Code § 3011
(a) In making a determination of the best interests of the child in a proceeding described in Section 3021, the court shall, among any other factors it finds relevant and consistent with Section 3020, consider all of the following:
(1) The health, safety, and welfare of the child.

(2) (A) A history of abuse by one parent or any other person seeking custody against any of the following:

(i) A child to whom the parent or person seeking custody is related by blood or affinity or with whom the parent or person seeking custody has had a caretaking relationship, no matter how temporary.

(ii) The other parent.

(iii) A parent, current spouse, or cohabitant, of the parent or person seeking custody, or a person with whom the parent or person seeking custody has a dating or engagement relationship.

(B) As a prerequisite to considering allegations of abuse, the court may require independent corroboration, including, but 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 sexual assault or domestic violence. As used in this paragraph, “abuse against a child” means “child abuse and neglect” as defined in Section 11165.6 of the Penal Code and abuse against any other person described in clause (ii) or (iii) of subparagraph (A) means “abuse” as defined in Section 6203.

(3) The nature and amount of contact with both parents, including as provided in Sections 3046 and 3100.

(4) The habitual or continual illegal use of controlled substances, the habitual or continual abuse of alcohol, or the habitual or continual abuse of prescribed controlled substances by either parent. Before considering these allegations, the court may first require independent corroboration, including, but not limited to, written reports from law enforcement agencies, courts, probation departments, social welfare agencies, medical facilities, rehabilitation facilities, or other public agencies or nonprofit organizations providing drug and alcohol abuse services. As used in this paragraph, “controlled substances” has the same meaning as defined in the California Uniform Controlled Substances Act (Division 10 (commencing with Section 11000) of the Health and Safety Code).

(5) (A) When allegations about a parent pursuant to paragraph (2) or (4) have been brought to the attention of the court in the current proceeding, and the court makes an order for sole or joint custody or unsupervised visitation to that parent, the court shall state its reasons in writing or on the record that the order is in the best interest of the child and protects the safety of the parties and the child. In these circumstances, the court shall ensure that any order regarding custody or visitation is specific as to time, day, place, and manner of transfer of the child as set forth in subdivision (c) of Section 6323.

(B) Nothing in this paragraph eliminates the requirement that the contents of the stipulation be in the best interest of the child and be specific as to time, day, place, and manner of transfer of the child if the parties do stipulate in writing or on the record regarding custody or visitation.

(b) Notwithstanding subdivision (a), the court shall not consider the sex, gender identity, gender expression, or sexual orientation of a parent, legal guardian, or relative in determining the best interests of the child.

3020. (a) The Legislature finds and declares that it is the public policy of this state to ensure that the health, safety, and welfare of children shall be the court’s primary concern in determining the best interests of children when making any orders regarding the physical or legal custody or visitation of children. The Legislature further finds and declares that children have the right to be safe and free from abuse, and that the perpetration of child abuse or domestic violence in a household where a child resides is detrimental to the health, safety, and welfare of the child.
(b) The Legislature finds and declares that it is the public policy of this state to ensure that children have frequent and continuing contact with both parents after the parents have separated or dissolved their marriage, or ended their relationship, and to encourage parents to share the rights and responsibilities of child rearing in order to effect this policy, except when the contact would not be in the best interests of the child, as provided in subdivisions (a) and (c) of this section and Section 3011.
(c) When the policies set forth in subdivisions (a) and (b) of this section are in conflict, a court’s order regarding physical or legal custody or visitation shall be made in a manner that ensures the health, safety, and welfare of the child and the safety of all family members.
(d) The Legislature finds and declares that it is the public policy of this state to ensure that the sex, gender identity, gender expression, or sexual orientation of a parent, legal guardian, or relative is not considered in determining the best interests of the child.
(Amended by Stats. 2019, Ch. 551, Sec. 2. (SB 495) Effective January 1, 2020.)
