Advantages of a Living Trust for High-Income Families in California and Washington

By Kevin Luu, Co-Founder and Chief Learning Officer. Reviewed on 2026-09-30.

The main advantages of a living trust are that your assets pass to your family without probate court, the details stay private, a person you chose can manage the money if you become incapacitated, and money left to young children is held on your terms instead of under a court-appointed guardian. A living trust does not lower your income tax or your estate tax by itself, and it does not shield assets from creditors. For a California family with a house and a brokerage account, avoiding probate alone can be worth six figures.

This guide is written for two-income W-2 households in California and Washington with children under 12: a physician and a biotech scientist, two tech employees with RSUs, an executive whose pay is mostly equity. It covers what a revocable living trust actually does, what it does not do, and how the numbers work at your income level.

What a revocable living trust is

A revocable living trust is a legal document that you sign while you are alive. You (usually both spouses) are the trustees and the beneficiaries during your lifetime. You retitle your house and taxable accounts into the trust’s name, and you keep full control: you can buy, sell, refinance and change the terms at any time. When you die or cannot act, a successor trustee you named steps in and follows your written instructions.

The trust becomes effective as soon as it is signed and funded. It only controls assets that are titled in its name or that name it as beneficiary. An unfunded trust does very little.

While you are alive, a revocable trust is a grantor trust for income tax purposes. Nothing changes on your Form 1040, and the trust generally uses your Social Security number rather than its own (Treas. Reg. §1.671-4). For more on when a trust needs its own number, see do trusts have tax ID numbers.

Advantage 1: Avoiding California probate and its statutory fees

California sets probate fees by statute. The executor and the executor’s attorney are each entitled to a fee based on the gross value of the probate estate: 4% of the first $100,000, 3% of the next $100,000, 2% of the next $800,000, 1% of the next $9 million and 0.5% of the next $15 million (Cal. Probate Code §10800 and §10810).

The detail that matters most for Bay Area and Southern California homeowners: the value is measured “without reference to encumbrances.” Your mortgage is not subtracted. A $2.8 million house with a $1.6 million loan counts as $2.8 million.

Probate is also slow and public. It runs through court filings, notices and hearings, and the petition and inventory become part of a court file anyone can look up. Assets held in a properly funded trust skip that process; the successor trustee transfers them privately.

Worked example: a $1.2 million Bay Area household

Assumptions (illustrative): married parents in San Mateo County, combined W-2 income of $1.2 million, two children ages 4 and 7. They own:

• Home worth $2,800,000 with a $1,600,000 mortgage
• Taxable brokerage account of $600,000
• Vested company shares from RSUs worth $400,000
• 401(k)s of $900,000 and $5,000,000 of term life insurance, both with named beneficiaries

Retirement accounts and life insurance pass by beneficiary designation, so they stay out of probate either way. The other three assets are titled in the parents’ names. If both parents die together, or when the surviving parent later dies, those assets go through probate.

The family’s actual equity in those three assets is $2,200,000 ($1,200,000 in the house plus $1,000,000 in securities). The $102,000 is about 4.6% of that equity, before court costs, appraisal and any extra fees a court approves for extraordinary work. A family member serving as executor can waive their fee, but the attorney’s fee still applies. A living trust, drafted and funded properly, typically costs a small fraction of that.

At the first spouse’s death, California often lets property left to the surviving spouse pass without a full probate (Cal. Probate Code §13500), though a court petition may still be needed to confirm it. The large exposure is at the second death, or when both parents die at once, which is exactly the case parents of young children plan for.

Advantage 2: Money for young children is held on your terms

This is the advantage that matters most for parents of children under 12. Minors cannot own significant property outright. If your children inherit directly, with no trust, a court may appoint a guardian of the estate to manage the money (Cal. Probate Code §1514), with ongoing court oversight. Whatever is left typically goes to the child outright at 18.

Custodial accounts have the same problem in a milder form. Under California law, a UTMA transfer ends at 18 by default, and can be delayed to no later than 21 for a lifetime gift or 25 for a transfer under a will or trust (Cal. Probate Code §3920.5). Washington’s UTMA ends at 21 for gifts, with an option to extend to 25 in the initial nomination (RCW 11.114.200). See what happens to a UTMA when a child turns 21.

A trust lets you decide. Common patterns for families at this income level: the trustee pays for education, health and living costs as needed; the child receives a third at 25, half the remainder at 30 and the rest at 35; or the trust stays in place for life with the child gaining more control over time. In the example above, the $5,000,000 of life insurance is the largest single asset. If the policy names the trust as beneficiary instead of the children, that money is managed under your instructions rather than by a court-appointed guardian. The same applies to brokerage accounts: here is how to name a trust as beneficiary.

A trust is also not the usual place to name the guardian who raises your children. California lets a parent nominate a guardian in a signed writing (Cal. Probate Code §1500 and §1502), and the standard place for that nomination is your will. Most trust-based plans include a short “pour-over” will that names the guardian and sends any stray assets into the trust.

Advantage 3: Someone you chose manages money if you are incapacitated

If a parent has a serious accident or illness, assets in that parent’s name can be hard to manage. Without planning, the family may need a court conservatorship to sell the house or handle accounts. With a funded trust, the co-trustee spouse or the named successor trustee simply continues. Pair the trust with a durable power of attorney (for assets outside the trust) and an advance health care directive.

Advantage 4: Privacy and fewer grounds for family disputes

A will that goes through probate becomes part of a public court file. A trust is administered privately. For families with significant equity compensation, a well-known employer or a public-facing medical practice, that privacy has real value. Trusts can still be challenged, but there is no court proceeding by default, and clear written instructions leave less room for disagreement.

Advantage 5: Property in more than one state

A Seattle family with a cabin near Lake Tahoe, or a California family with a condo in Hawaii, can face a second, separate probate in the state where the property sits. Holding out-of-state real estate in the trust typically avoids that ancillary proceeding.

California vs Washington: how much the trust is worth

For a Washington family, a plain revocable trust does not reduce the state estate tax. A household with a home, RSUs and life insurance can pass the Washington exclusion more easily than they expect. Married couples above that level often ask their attorney to build a credit shelter (bypass) provision into the trust so that the first spouse’s exclusion is used. That is a drafting decision, not a reason to skip the trust.

What a living trust does not do

• No income tax savings. The original version of this article said living trusts provide significant tax benefits. They do not. A revocable trust is ignored for income tax while you are alive.
• No federal estate tax savings by itself. The federal basic exclusion is $15,000,000 per person for 2026 (IRS), so most families in this income range are below it today. Reducing a taxable estate takes irrevocable planning, which is a separate conversation.
• No creditor protection. Because you can revoke it, your creditors can reach the assets.
• No effect on the step-up in basis. California and Washington are community property states. Community property held in a revocable trust can keep its community character, which matters because the surviving spouse’s half of community property can also receive a new basis at the first death (IRC §1014(b)(6)). Ask your attorney to confirm how the trust characterizes your property.

Common mistakes we see

1. Signing the trust and never funding it. The house deed, brokerage accounts and vested company shares need to be retitled. New accounts opened later often get missed.
2. Leaving life insurance and retirement beneficiaries pointing at the children. Minor children as direct beneficiaries can bring back the court guardianship the trust was meant to avoid. For retirement accounts, naming a trust has tax consequences, so get advice before changing it.
3. Choosing a successor trustee by default. A sibling who is kind but disorganized may not be the right person to manage $5 million for 25 years. Some families split the roles: a family member as guardian, a different person or a professional as trustee. See whether a financial adviser can serve as executor.
4. Never updating it. A trust drafted before your second child, a move from Washington to California, or a large RSU grant may no longer fit.

What to write down for your children

A trust tells the trustee what to do. It rarely tells your children why. Alongside the legal documents, write a one-page letter for each child: why you set the distribution ages you chose, what you hope the money pays for, and how you thought about work and giving when you were building it. Keep it with the trust and update it when you update the plan. Conversations fade. Documentation compounds.

Frequently asked questions

When does a living trust become effective?

A living trust becomes effective when you sign it, but it only controls assets that you have retitled into it or that name it as beneficiary. Until you fund it, your house and accounts still pass under your will or by intestacy, which in California typically means probate. Funding is a separate step from signing, and it is the step families most often leave unfinished.

Is a family trust the same as a living trust?

Usually, yes. “Family trust” is an informal name for a revocable living trust that a married couple sets up for themselves and their children, for example “The Chen Family Trust.” It is not a separate legal category. The advantages above apply the same way. For how a trust compares with a family LLC, see family trust vs LLC.

Do we still need a will if we have a living trust?

Yes. Parents of minor children typically use the will to nominate a guardian for the children, because that is not the job of the trust. The will is usually a short pour-over will that moves any assets left outside the trust into it at death. Those assets may still go through probate, which is why funding the trust carefully matters.

Next step

Pull your house deed and a list of your accounts, and check which ones are titled in a trust and which beneficiaries are named on your life insurance and 401(k)s. That list is the starting point for an estate attorney and for our estate planning and family governance work at Age Five Family Office™. If you would like a second set of eyes on how your trust, equity compensation and taxes fit together, the Tax & Wealth Assessment is a good place to start.

This is general education, not legal or tax advice. The right structure depends on your family’s full picture and should be drafted by an estate attorney licensed in your state.
