5 Vital Estate Plan Documents [2026]

Short answer: A complete California estate plan needs five documents: a will, a revocable living trust, a durable power of attorney, a health care power of attorney, and a living will (often combined with the health care power of attorney into one advance directive). The trust, not the will, is what keeps your estate out of probate, and only if you actually retitle your assets into it. Skip the will entirely and California’s intestate succession statutes decide who inherits, not you. Skip the power of attorney and health care directive and your family may have no legal authority to act for you if you become incapacitated.

What are the five documents in a complete estate plan?

Each document does a different job. None of them substitutes for the others.

• Last will and testament. Names who inherits your property, who administers your estate, and who raises your minor children if needed. It only takes effect once a court validates it through probate.
• Revocable living trust. Holds title to your assets while you’re alive and directs their distribution when you die, without a probate court’s involvement, but only for assets actually retitled into the trust’s name.
• Durable power of attorney. Names someone to manage your finances, pay bills, and handle property if you can’t act for yourself.
• Health care power of attorney. Names someone to make medical decisions for you if you can’t communicate them yourself.
• Living will. States your own wishes about end-of-life medical treatment, so the person holding your health care power of attorney isn’t guessing. In California this is commonly combined with the health care power of attorney into a single advance health care directive.

A will and a trust handle what happens after death. A power of attorney and a health care directive handle what happens if you’re alive but unable to act. A complete plan covers both situations, not just one.

Does a will keep your estate out of probate?

No. A will has to go through probate before it does anything. Probate is the court process that validates the will, appoints your executor, and supervises the distribution of your assets. Only a properly funded revocable living trust moves assets to your beneficiaries outside that process.

California requires formal probate for an estate with assets subject to probate totaling more than $208,850 in gross value, for deaths on or after April 1, 2025, under Probate Code § 13100. Below that threshold, simplified transfer procedures are often available instead. If you die without a will at all, California’s intestate succession statutes under Probate Code § 6400 decide who inherits, and that estate still goes through the same court process if it’s above the threshold.

What does a living trust do that a will can’t?

A funded revocable living trust avoids probate for the assets titled in its name. A will, on its own, never avoids probate, it only tells the probate court what to do once probate has already started. That’s the core difference, and it’s the reason most California estate plans built around a trust use a short backup will (a pour-over will) rather than relying on the will alone.

The word “funded” carries the weight here. A living trust that’s signed but never used, meaning the house, accounts, and other assets were never retitled into the trust’s name, does not avoid probate for those un-retitled assets. Signing the trust document is the easy part. Actually moving title into the trust is the part that determines whether your family sees a courtroom.

What happens if you become incapacitated without a power of attorney?

Without a durable power of attorney, no one automatically has legal authority to pay your mortgage, access your bank accounts, or manage your investments if a stroke, accident, or advancing dementia leaves you unable to handle your own affairs. Your spouse’s name being on some accounts doesn’t cover everything you own. Your family may have to ask a court to appoint someone to manage your finances for you, which is slower, more public, and more expensive than naming someone yourself in advance.

The same gap exists on the medical side. Without a health care power of attorney, doctors and hospitals may not have clear legal direction about who speaks for you, and without a living will, whoever is authorized to speak for you is left guessing what you would have wanted. Naming an agent and writing down your wishes while you’re capable of doing so removes that guesswork from the people who love you.

How often should these documents be reviewed?

Review your plan after the events that actually change it: a marriage, a divorce, a death in the family, the birth of a child or grandchild, a move to or from California, or a significant change in what you own. A durable power of attorney or health care directive naming an agent who has since died, moved away, or become estranged is worse than having no document at all, because it creates false confidence that someone is covered when no one actually is. Periodic review, not a one-time signing, is what keeps a plan usable when it’s needed.

What to do next

If you have none of these five documents, start with the will and the power of attorney and health care directive, since those cover the situations most likely to arise first. If you have a will but no trust, ask whether your assets are worth the cost of probate before assuming a will is enough. An estate planning attorney can walk through which of these documents you’re missing and what it takes to actually fund a living trust or put a power of attorney in place correctly.
