What this means in practice

Intestate succession rules apply only to probate property. Assets with a named beneficiary or a survivorship feature, such as life insurance, retirement accounts, payable-on-death accounts, jointly owned property with a right of survivorship and transfer-on-death deeds, usually pass outside these rules.

Family situations change the result. Children from a prior relationship, adopted children, a pending divorce or a legal separation can all affect who inherits and in what shares, so check how the statute treats each of these before relying on a simple summary.

Real estate is generally governed by the law of the state where it is located, while other property usually follows the law of the state where the person lived. A person who owns land in more than one state may have more than one set of rules apply to the estate.

General information, not legal advice. Laws change, and cities can add their own rules, so check the current statute before you rely on it.
