C.R.S. § 15-11-114

(1) A parent is barred from inheriting from or through a child of the parent if: (a) The parent’s parental rights were terminated and the parent-child relationship was not judicially reestablished; or (b) The child died before reaching eighteen years of age and there is clear and convincing evidence that immediately before the child’s death the parental rights of the parent could have been terminated under the laws of this state other than this code on the basis of nonsupport, abandonment, abuse, neglect, or other actions or inactions of the parent toward the child. (2) For the purpose of intestate succession from or through the deceased child, a parent who is barred from inheriting under this section is deemed to have predeceased the child.
