A legal document saying what you want done with what you own, and who you trust to carry it out. Without one, the state has a default order and it applies regardless of what everybody knows you intended. A will is you writing the instructions instead of leaving them to a statute.
What Happens Without One
Every state has rules for who receives what when there are no instructions. Those rules don't know your family. They don't know which child has worked the place for fifteen years and which one left at eighteen.
They'll be applied anyway, and the result is frequently not what anybody would have chosen.
It Does Not Control Everything
This is the part people get wrong. Accounts and policies with a named beneficiary typically pass by that designation, not by the will. Jointly held property often passes outside it too.
So a perfect will and a stale beneficiary form still produce the wrong outcome. Both have to be right.
Name the Person, Too
A will also names who administers things. That job is real work, often during the worst weeks of somebody's life, and the right choice isn't automatically the oldest child.
Get a will drafted by an attorney in your state. The requirements are specific enough that a form found online can fail precisely when it matters.
