Who is considered a "family member"?

A family member is a parent, spouse, or child of the employee. "Child" means a biological, adopted, or foster child, a stepchild, a legal ward, or a child of an employee who stands in place of a parent (that is, who is charged with a parent's rights, duties, and responsibilities) to that child who is either under 18 years of age or is an adult dependent child. An adult dependent child is an individual who is incapable of self-care because of a mental or physical disability within the meaning of Government Code section 12926.
