Child custody disputes usually occur between a child’s parents. In some circumstances, however, a grandparent, relative, caregiver, or another nonparent may have developed such a significant parenting relationship with a child that custody becomes an issue.

California family courts can award custody to a nonparent in appropriate circumstances, but the standard is significantly different from an ordinary custody dispute between two parents.

A Nonparent Must Meet a Higher Custody Standard

When custody is disputed between parents, the child’s best interests are central to the court’s determination.

A nonparent seeking custody over a parent’s objection faces an additional requirement.

The court must find that granting custody to the parent would be detrimental to the child and that awarding custody to the nonparent is required to serve the child’s best interests.

Importantly, “detriment” does not necessarily require a finding that the parent is legally unfit.

California replaced the older parental-unfitness approach with a detriment standard. This allows the court to examine the effect that changing the child’s established caregiving arrangement could have on the child.

What if the Child Has Been Living With the Nonparent?

An established caregiving relationship can become particularly important.

The source materials explain that detriment can arise from removing a child from a stable placement with someone who has assumed the day-to-day role of a parent for a substantial period of time.

That relationship involves more than simply spending time with the child. The person may have been meeting the child’s physical needs while also providing the psychological care and affection associated with a parental relationship.

When the required showing concerning that type of established caregiver is made, California law provides specific presumptions concerning the child’s best interests and detriment from parental custody.

The circumstances remain highly fact-specific.

How Does a Nonparent Become Part of the Family Law Case?

Procedure is important.

The source materials explain that a third-party caregiver may seek joinder in an existing family law proceeding and request custody. A nonparent does not use that same provision to simply initiate an independent family court custody action.

Joinder formally brings the nonparent into the existing case so that their request and the competing parental rights can be addressed.

Depending on the circumstances, other legal proceedings—such as a guardianship—may also be relevant, but they are procedurally different from seeking custody through joinder in an existing family law case.

Nonparent Custody Is an Exceptional Remedy

A close relationship between a child and a grandparent or caregiver does not automatically create a right to custody.

California’s standard recognizes the importance of parental custody while also allowing courts to address circumstances in which removing a child from an established caregiving arrangement would be detrimental.

When a nonparent has effectively filled a parental role for a substantial period, the history and stability of that relationship can therefore become highly important to the custody analysis.
