Who usually inherits first under intestate succession laws?

Under modern intestate succession laws, the surviving spouse is almost universally granted a primary position in the order of inheritance, often receiving a significant portion or the entirety of the estate depending on the presence of other surviving relatives, such as children or parents.1234

When an estate is not fully claimed by a surviving spouse, or if there is no surviving spouse, the assets typically pass to the decedent's relatives based on their degree of kinship. While specific statutes vary by jurisdiction, the general order of priority follows these principles:

• Descendants: The decedent’s children (and their issue) usually inherit first among blood relatives.15
• Parents: If there are no surviving descendants, the decedent’s parents are typically next in line.15
• Collateral Relatives: If no descendants or parents survive, the estate generally passes to siblings and their descendants, followed by grandparents and their descendants (often organized by the parentelic system).15

Historically, systems like those in ancient Rome prioritized bloodlines and agnatic relatives, often excluding the surviving spouse unless no other kin could be found. Modern legal reforms have shifted significantly to prioritize the financial security of the surviving spouse.623
