What Happens If You Die Without a Will?

Every state has a backup estate plan written into its statutes. It applies to everyone who dies without one of their own. Here's what that default plan actually does — and where it surprises people.

The intestacy formula: reasonable, rigid, and blind

Intestacy statutes distribute your probate estate by relationship category: a surviving spouse first, children and their descendants next, then parents, siblings, and outward through the family tree. The details — how a spouse shares with children, how stepchildren are treated, what happens with half-siblings — vary meaningfully from state to state, and in community property states the formula treats community and separate property differently.

What the formula can never do is know your family. It doesn't know that one child cared for you for a decade, that you're estranged from a relative, that your dearest people aren't blood relatives at all. It applies arithmetic to a category, and the result may look nothing like what you'd have chosen.

The people intestacy leaves out entirely

• Unmarried partners. However long the relationship, intestacy statutes generally recognize only spouses and blood relatives. A partner of thirty years can receive nothing.
• Stepchildren you never adopted, in many states.
• Friends, godchildren, charities — anyone outside the statutory family tree.

Minor children: the part parents most need to hear

A will is where you nominate a guardian for your children. Without one, a judge chooses among willing relatives, guided by the child's best interests — a stranger making the most personal decision in your family's life, without your voice in the record. Any basic estate plan, will-based or trust-based, fixes this.

What intestacy does NOT control

Only property that would pass through probate follows the intestacy formula. Everything with its own transfer mechanism keeps working: life insurance and retirement accounts go to named beneficiaries, survivorship property goes to the co-owner, and property in a living trust passes by the trust's terms. That's both a comfort and a warning — outdated beneficiary forms (an ex-spouse, a deceased parent) can control large assets no matter what the intestacy formula says, and no matter what you would have wanted.

The fix is genuinely simple

Everything above — the rigid formula, the court-chosen guardian, the left-out partner — is fixed by having a plan of your own: a will at minimum, a trust-based plan if probate avoidance matters to you (the tradeoff is laid out in living trust vs. will). How your state's intestacy formula would treat your specific family, and what plan best replaces it, are personal questions worth confirming with a licensed attorney in your state — but "have a plan instead of the default" is the rare piece of estate planning guidance that applies to almost everyone.
