I'd suggest looking on the SC website for "Intestate Succession"
For example, here's the chart for WI
If you die, your spouse gets your stuff.
If the divorce is final, then they don't.
Next is your kids. If they're minors then a guardian handles the estate, usually for a fee.
If you don't have kids, then your parent(s).
If your parents have past, then brothers and sisters.
Make sense? Remember, this is only WI.
I was able to execute my mother's estate, with a will, without a lawyer.
Lots of forms, a few letters to the judge, took almost a year.
