f. An order or judgment awarding kinship legal guardianship may be vacated by the court prior to the child's 18th birthday if the court finds that the kinship legal guardianship is no longer in the best interests of the child or, in cases where there is an application to return the child to the parent, based upon clear and convincing evidence, the court finds that the parental incapacity or inability to care for the child that led to the original award of kinship legal guardianship is no longer the case and termination of kinship legal guardianship is in the child's best interests.
In cases in which the division was involved, when determining whether a child should be returned to a parent, the court may refer a parent for an assessment prepared by the division, in accordance with regulations adopted by the commissioner.
