C.R.S. § 15-11-116
COMMENT
Scope. This section provides that if a parent-child relationship exists or is established under any section in subpart 2, the consequence is that the parent is a parent of the child and the child is a child of the parent for the purpose of intestate succession by, from, or through the parent and the child. The exceptions in Section 2-119(b) through (e) refer to cases in which a parent-child relationship exists but only for the purpose of the right of an adoptee or a descendant of an adoptee to inherit from or through one or both genetic parents.
For other provisions on establishing parent-child relationships, see the "Uniform Parentage Act", article 4 of title 19.
