Primary heirs are individuals who are first in line to inherit assets and property from a deceased person, typically defined by law or a will. These heirs usually include close family members such as spouses, children, or parents, depending on the jurisdiction and the deceased's wishes. In the absence of a will, intestate succession laws determine who the primary heirs are. This process ensures that the deceased's estate is distributed fairly among their closest relatives, following a specific order of priority established by state or country laws.
