"Issue" is a legal term used to encompass the generations of descendants that follow an individual to form a family lineage.
In probate and Estate Planning, the term "issue" is often used to determine the Inheritance rights of descendants when a person dies without a Last Will and Testament or when a will contains provisions related to the person's descendants.
For example, if a person's will states, "I leave my estate to my daughter and her issue," this means that the daughter is the primary Beneficiary, and if the daughter has children, they would also inherit a share of the estate as her "issue."
In the context of Intestacy (when a person dies without a valid will), laws of Intestate Succession define how an estate is distributed among the deceased's closest relatives, including their spouse, children, and issue.
The term "issue" ensures that the inheritance is passed down to direct descendants in a clear and organized manner.
