An act/event conferring inheritance rights generally has effect only from the date
of such act/event. Submit to the Office of the General Counsel (OGC) per GN 01010.815 ff. if the date is material and you have no precedent opinion on whether the act
or event has any retroactive effect under State law.
See the NOTE at the beginning of the Louisiana entry in GN 00306.505 for an explanation of, and effective dates for, Louisiana legitimation and inheritance
If a provision in GN 00306.400 - GN 00306.680 shows that a State law confers inheritance rights based on an adjudication of paternity
(but does not legitimate the child), and the provision is effective prospectively
only, the claimant's status as the NH's child is established effective with the following
if one piece of evidence satisfies the applicable standard of proof (e.g., blood test
results constitute clear and convincing evidence), the date of that piece of evidence;
if more than one piece of evidence is needed to satisfy the applicable standard of
proof, the date of the latest necessary piece of evidence.
