Generally, a person who has not attained maturity or the age of legal majority is a child. Pursuant to section 1-201 of Uniform Probate Code, a Child includes an individual entitled to take as a child under the Probate Code by intestate succession from the parent whose relationship is involved. The Code excludes from the definition of “child” a person who is only a stepchild, a foster child, a grandchild, or any more remote descendant.
