HRS §560:2-708
How property is split among descendants if the will doesn't say
When a will or trust gives property to a group like 'descendants' or 'issue' but doesn't say how to divide it, the property goes to those living when the gift takes effect. They share it as if the named ancestor had died without a will at that time.

The statute, as written — Class gifts to "descendants", "issue", or "heirs of the body"; form of distribution if none specified
If a class gift in favor of "descendants", "issue", or "heirs of the body" does not specify the manner in which the property is to be distributed among the class members, the property is distributed among the class members who are living when the interest is to take effect in possession or enjoyment, in such shares as they would receive, under the applicable law of intestate succession, if the designated ancestor had then died intestate owning the subject matter of the class gift.
