Ingenealogy and wills, a person'sissue means all theirlineal descendants.
Issue typically means a person'slineal descendants—all genetic descendants of a person, regardless of degree.[1] Issue is a narrower category than heirs, which includes spouses, and collaterals (siblings, cousins, aunts, and uncles).[2] This meaning ofissue arises most often in wills andtrusts.[3] A person who has no living lineal descendants is said to have diedwithout issue.
A child or children are first-generation descendants and are a subset of issue.[4]
