Haw. Rev. Stat. § 560:2-114: Parent barred from inheriting in certain circumstances.

(a) A parent shall be barred from inheriting from or through a child of the parent if:

(1) The parent's parental rights were terminated and the parent-child relationship was not judicially reestablished; or

(2) 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 chapter, on the basis of nonsupport, abandonment, abuse, neglect, or other actions or inactions of the parent toward the child.

(b) For the purpose of intestate succession from or through the deceased child, a parent who is barred from inheriting under this section shall be treated as if the parent predeceased the child.

(c) Except as otherwise provided in section 560:2-125(b), the termination of a parent's parental rights to a child shall have no effect on the right of the child or a descendant of the child to inherit from or through the parent.
