What Is a Will, and What Does It Do?

Short answer: A will is a signed legal document that says who gets your property and who should raise your minor children if you die while they are still young. It does not skip probate. A California court still has to validate the will before it controls anything, and if you die without one, state intestacy law decides who inherits instead of you, under Probate Code § 6400.

What does a will actually do?

A will names the person you want to receive specific items, accounts, or property, and it names an executor, the person responsible for carrying out those instructions once you are gone. If you have minor children, a will also lets you nominate a guardian, the adult you want raising them if both parents are unavailable. None of this happens automatically. Without a signed will, a probate court decides who inherits and, separately, who is best suited to raise your children, using its own judgment rather than yours.

A will does not control everything you own. Property held in joint tenancy, payable-on-death or transfer-on-death accounts, and life insurance or retirement accounts with a named beneficiary generally pass directly to that co-owner or beneficiary regardless of what the will says. A will only governs what is titled in your name alone.

What happens in California if you die without one?

If you die without a valid will, California’s intestate succession statutes decide who inherits, not your wishes and not your family’s assumptions about what you would have wanted. Under Probate Code § 6401, a surviving spouse takes all of the couple’s community and quasi-community property. Separate property is split differently depending on who survives you: the spouse gets everything if there are no surviving children, parents, or siblings; half if there is one child or that child’s descendants, or no children but a surviving parent or sibling; and one-third if there are two or more children.

If nothing passes to a spouse, or you were not married, Probate Code § 6402 sends the estate down a fixed line: first to your children and their descendants, then to your parents, then to your siblings and their children, and outward from there. That fixed order does not bend for people you were close to but never legally connected to. Stepchildren who were never adopted and unmarried partners generally inherit nothing under intestate succession, no matter how long the relationship lasted.

Does having a will avoid probate?

No. A will only takes effect once a court validates it through probate. Having a will can make that process smoother, a clear document reduces the odds of a dispute, but it does not remove the court from the picture. Dying without a will does not avoid probate either. An intestate estate above the small estate threshold still goes through the same court-supervised process, under the same statutory fee schedule that applies to any other probate.

The only way to keep assets out of probate entirely is to hold them in a form that passes outside of it: a properly funded revocable living trust, joint tenancy, or accounts and policies with a named beneficiary. A will and a living trust do different jobs, and conflating them is one of the more expensive mistakes people make in their own planning.

Who takes charge if you don’t name an executor?

If your will names an executor, the court appoints that person under Probate Code §§ 8400 through 8402. If you have no will, or your will fails to name anyone able and willing to serve, the court appoints an administrator instead, chosen from a statutory priority list under Probate Code §§ 8460 through 8469. That list runs roughly from a surviving spouse, to children, to other relatives, in a fixed order set by statute. It does not ask who was closest to you or who you would have trusted most. Naming your own executor is one of the simplest ways to make sure the person handling your affairs is someone you actually chose.

Common misconceptions about wills

A will is not just for people with substantial assets or people who are older. Anyone who wants to control who raises their children, or who inherits a specific item, benefits from having one. A will also is not a substitute for a living trust if your goal is to avoid probate. And a will is not permanent. You can revise it any time your circumstances change, and in most cases you should.

When should you update a will?

Marriage, divorce, the birth of a child, the death of a beneficiary or named executor, or a significant change in what you own are all reasons to pull your will back out and look at it again. A will written for a life you no longer have will not reliably produce the outcome you want. Review it after any major life event rather than assuming it still says what you meant.

What to do next

If you do not have a will, or the one you have predates a marriage, a divorce, a child, or a move to California, that is worth fixing before it becomes someone else’s problem to sort out in probate court. An estate planning attorney can put a will in place, or pair it with a living trust if avoiding probate entirely is the actual goal.
