Grandparents are great; but great-grandparents are not “grandparents.” Following the dissolution of a marriage, the grandmother of a child’s mother (Great-grandmother), sought visitation rights. Father objected. The trial court allowed Great-grandmother to intervene to seek visitation. Father obtained interlocutory review pursuant to CRS 13-4-102 and CAR 4.2. The court of appeals reversed. Under CRS 19-1-117 and CRS 19-1-103(56) a “grandparent” is “a person who is the parent of child’s father or mother.” Great-grandparents are not such a person. Although the Children’s Code is liberally construed in favor of the best interests of the child, unambiguous language, combined with the protection of parents’ rights under Troxel v. Granville, do not permit an expansion of the definition of grandparent. Thus, Great-grandmother lacked standing to seek visitation.
