Short answer: A complete California estate plan has four core documents: a will, a funded revocable living trust, a durable power of attorney, and an advance health care directive. A will alone does not avoid probate; only a revocable living trust that actually holds your assets does that. If you die without a will, California’s intestate succession statutes, not your wishes, decide who inherits, under Probate Code § 6400. Skipping any one of these four documents leaves your family to solve the gap in court.
What documents belong in a California estate plan checklist?
Four documents do almost all of the work. A last will and testament names who receives what is left in your name alone at death and, if you have minor children, lets you nominate a guardian for them. A revocable living trust holds title to assets you transfer into it during your lifetime and passes them to your beneficiaries without a probate court proceeding. A durable power of attorney names someone to manage your finances if you become unable to. An advance health care directive names someone to make medical decisions for you and states your treatment wishes if you cannot speak for yourself.
Most complete plans pair a revocable living trust with a short pour-over will, the power of attorney, and the health care directive, plus a deed that actually moves your California real estate into the trust. Leaving out the deed is one of the most common and expensive mistakes: a trust that does not hold your house does not keep your house out of probate.
Does a living trust replace the need for a will in California?
No. A will requires probate to take effect; it does not avoid probate on its own. Only a funded revocable living trust, meaning one where your assets have actually been retitled into it, passes property to your beneficiaries outside of probate. The will still matters because it catches anything left out of the trust, names a guardian for minor children, and gives the court direction if something was missed.
If you die without a will at all, California’s intestate succession statutes decide who inherits, not you. A surviving spouse generally takes all community and quasi-community property. Separate property is divided by a statutory formula among the spouse, children, parents, or siblings depending on who survives you. Stepchildren who were never legally adopted, and unmarried partners, generally inherit nothing under intestate succession. Dying without a will does not avoid probate either; an intestate estate above the small estate threshold still goes through full, court-supervised probate.
What happens if the trust is never funded?
A living trust that sits in a binder with nothing retitled into it protects nothing. Any asset still in your individual name at death, real estate, bank accounts, investment accounts, has to go through probate for that asset regardless of what the trust document says. In California, an estate with more than $208,850 in gross probate assets, for deaths on or after April 1, 2025, requires formal, court-supervised probate under Probate Code § 13100. Funding the trust, meaning actually retitling your house, accounts, and other assets into it, is the step that keeps that number from ever becoming your family’s problem.
What do the power of attorney and health care directive actually do?
A durable power of attorney lets you choose, in advance, who handles your bills, your accounts, and your property if illness or injury leaves you unable to manage them yourself. Without one, your family may have to ask a court to appoint someone to act for you, a slower and more public process than simply having the document ready.
An advance health care directive does the same thing for medical decisions. It names an agent to speak for you if you cannot speak for yourself and lets you record your own wishes about treatment, so your family is not left guessing, or arguing, during a medical crisis. Both documents only work if they exist before you need them. Neither one can be signed once you have already lost capacity.
When should you update these documents?
Review your plan after marriage, divorce, the birth or adoption of a child, the death of a named executor, trustee, or agent, or a significant change in what you own. A plan built around your circumstances five years ago may name the wrong guardian, the wrong trustee, or leave out property you acquired since. An outdated beneficiary designation on a life insurance policy or retirement account can override what your will or trust says entirely, since those accounts pass by the beneficiary form, not by the will.
What to do next
Pull together what you already have, a will, a trust, a power of attorney, a health care directive, and check whether your home and major accounts are actually titled in the trust’s name. If any of the four documents is missing, undated, or built around a family situation that no longer matches your own, talk with an estate planning attorney about closing the gap before it becomes your family’s emergency.
