Revocable Trust Advantages for California and Washington Families With Young Children

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

The main advantages of a revocable living trust are that your assets can pass to your family without probate, your successor trustee can manage money if you become unable to, the details stay private, and you decide when and how your children receive what you leave them. You keep full control while you are alive and can change or cancel it at any time. What it does not do is cut your income tax, reduce estate tax on its own, or protect assets from your creditors.

For a California or Washington household earning $750,000 to $3 million with a home, a brokerage account, RSU shares and children under 12, those advantages are not abstract. In California, the gap between dying with and without a funded trust can run to six figures in statutory fees and many months in court. Below is how each advantage works, a worked example, and where a trust does not help.

What a revocable living trust is

A revocable living trust is a legal document that holds title to your assets. You (usually both spouses) are the trustors who create it, the trustees who manage it, and the beneficiaries while you are alive. You name a successor trustee to take over at incapacity or death, and you write the instructions for what happens to the assets, including for minor children.

While you are alive, the IRS treats the trust as you. It is a grantor trust, so it uses your Social Security number and you report its income on your normal Form 1040 under the optional reporting method in Treas. Reg. §1.671-4. There is no separate trust tax return to file in a typical setup.

The trust only controls what is titled in its name. The deed to your house, your taxable brokerage account and your bank accounts need to be retitled to the trust. Retirement accounts and life insurance stay in your name and pass by beneficiary designation instead.

Six advantages of a revocable trust, and who benefits most

1 and 2. Avoiding probate and its cost in California

California sets probate fees by statute. The executor and the estate’s attorney are each entitled to a fee of 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 §10810, and §10800 for the executor). The fee is calculated on the gross value of the probate estate, without subtracting the mortgage. A $3 million house with a $1.5 million loan counts as $3 million.

Washington probate is usually simpler and less expensive. There is no statutory percentage fee; the court allows compensation it deems just and reasonable (RCW 11.48.210). A solvent estate can often be administered with nonintervention powers, which lets the personal representative settle it with little court supervision (RCW 11.68.011). For Washington families, the advantages below (incapacity, children, privacy, out-of-state property) tend to matter more than the fee savings.

3. A successor trustee instead of a conservatorship

If one or both parents are injured or seriously ill, someone has to pay the mortgage, sell RSU shares to cover taxes, and manage the brokerage account. Without a trust or a durable power of attorney that the bank accepts, that can require a court conservatorship. With a funded trust, your named successor trustee steps in under the terms you wrote. For a dual-income household where one parent holds most of the equity compensation, this is often the advantage that matters first.

4. Control over money left to children under 12

This is the advantage most parents of young children underestimate. If assets pass to a minor outright, someone still has to manage them, and the default routes give you little say. A court-supervised guardianship of the estate ends when the child reaches majority (Cal. Probate Code §1600). A UTMA custodianship created by will or trust can run no later than age 25 in California (Cal. Probate Code §3920.5) and no later than 21, or 25 if the transferor extends it, in Washington (RCW 11.114.200). After that, the child controls the full balance. See what happens to a UTMA when the child turns 21.

A trust lets you set the rules: a separate trust for each child or one pot until the youngest finishes college, distributions for education and health, a third at 25, a third at 30, the rest at 35, and a trustee who is not necessarily the same person as the guardian who raises the kids. The guardian of the children is named in your will, which usually sits alongside the trust as a “pour-over” will.

5. Privacy

A probated will becomes a court record, and so does the estate inventory. A trust administration generally stays out of court. For families with a visible employer, a public-facing medical practice or a large equity stake, that keeps the size and destination of the estate off the public record.

6. Flexibility without a tax cost

Because you can revoke it, moving assets into the trust is not a gift and not a sale. In California, transferring your home into a revocable trust is excluded from a change in ownership, so it does not trigger a property tax reassessment (Cal. Rev. and Tax. Code §62(d)). At death, assets in the trust still receive a new cost basis at fair market value under IRC §1014, including the full community property step-up for married couples in California and Washington.

Worked example: a San Jose family with $1.4 million of W-2 income

Assumptions (illustrative): a married couple, both W-2 at large tech and biotech employers, two children ages 4 and 8. They own a home worth $2,800,000 with a $1,200,000 mortgage, a taxable brokerage account of $900,000, and $400,000 of vested RSU shares. Their 401(k)s ($1,100,000) name each other as primary beneficiaries and have contingent beneficiaries on file, so they pass outside probate either way. Everything is community property.

If both parents die without a funded trust, the probate estate is the home, the brokerage account and the RSU shares: $2,800,000 + $900,000 + $400,000 = $4,100,000 gross. The mortgage is not subtracted.

• Statutory fee for each of the executor and the attorney: $4,000 + $3,000 + $16,000 + 1% of $3,100,000 ($31,000) = $54,000.
• Executor plus attorney: $108,000, before court costs, appraisal and any extraordinary fees.
• The brokerage account and RSU shares ($900,000 + $400,000 = $1,300,000) would then be managed for the children under a court guardianship or a custodianship that ends between 18 and 25.

With a funded revocable trust, the same assets pass to the successor trustee without probate, and the trust holds them for the children on the schedule the parents chose. Suppose the trust-based plan cost $6,000 in attorney fees to draft (an illustrative assumption; quotes vary by attorney and complexity). The trade-off is roughly $6,000 now against about $108,000 in statutory fees later, plus months of court time.

A note on the first death: in California, community property passing to a surviving spouse can often be transferred with a simpler spousal property petition rather than a full probate (Cal. Probate Code §13650). The largest exposure for young families is the second death, or both parents dying together, which is exactly when the children are left with the least help.

What a revocable trust does not do

• No income tax savings. All income is still taxed to you at your rates: up to 37% federal for 2026 and 13.3% in California for 2025 (the latest published FTB schedule), the same as without a trust.
• No estate tax savings by itself. Trust assets are still in your taxable estate. For 2026 the federal basic exclusion is $15,000,000 per person, so few families at this income level owe federal estate tax. Washington is different: its estate tax exclusion is $3,000,000 for deaths from July 1 to December 31, 2026 (WA DOR estate tax tables). A Seattle couple with a $6 million home, portfolio and life insurance can owe Washington estate tax whether or not they have a revocable trust. Reducing that exposure takes planning written into the trust, such as a credit shelter trust at the first death, not the revocable trust alone.
• No creditor protection. In California, property in a revocable trust is subject to the trustor’s creditors during the trustor’s lifetime (Cal. Probate Code §18200).
• No help for unfunded assets. A trust that owns nothing does nothing. The most common failure we see is a signed trust with the house still in the parents’ names.

Common mistakes high-income families make

1. Never retitling the brokerage account. New accounts opened after signing (a new brokerage account, RSU shares that land at the equity plan administrator) are often left in individual names. Check where vested shares sit.
2. Beneficiary forms that skip the trust. Naming minor children directly on a 401(k) or life insurance policy can force a court guardianship. Many families name the spouse first and the trust second. See naming a trust as beneficiary of your brokerage account.
3. Choosing the wrong successor trustee. The person best suited to raise your children may not be the best person to manage $4 million. Splitting the roles is common.
4. Treating it as done. A trust drafted when the first child was born may not cover a second child, a move from Washington to California, or a large RSU grant. Review it every few years and after any major change.

What to document for your children

The trust says who gets what and when. It does not say why. A one-page letter to your successor trustee and, later, to your children can explain how you thought about the distribution ages, what you hoped the money would be used for, and what you would want the trustee to weigh in a hard call. Store it with the trust and update it when you update the plan. As Kevin Luu puts it: “Your kids will inherit your money. Will they inherit your judgment?”

Frequently asked questions

Do revocable trusts have costs after they are set up?

Usually little. There is no separate tax return while you are alive, because the trust reports under your Social Security number. The ongoing cost is mostly time: retitling new accounts, keeping beneficiary forms consistent, and paying an attorney to amend the document when your family or state of residence changes. After death, the successor trustee may hire an attorney and a CPA to administer the trust.

Is a revocable trust worth it in Washington if probate is cheaper?

Often yes for families with young children, though for different reasons. The trust still controls when the children receive money, avoids a guardianship of the estate, gives a successor trustee authority if a parent is incapacitated, and avoids a second probate on property in another state, such as a California vacation home. Washington families with estates over the state exclusion also use the trust document to hold estate tax planning.

What is the difference between a revocable trust and a trust fund?

“Trust fund” is a casual term for money held in a trust for someone, usually a child. A revocable living trust is one type of trust you set up for yourself while alive. At your death it becomes irrevocable, and the shares held for your children are what people would call trust funds, managed by your trustee under your rules.

Next step

Pull the deed to your house and the titling on each brokerage account, and check whether they are in the trust’s name. If you do not have a trust yet, list the people you would trust to raise your children and the people you would trust with the money, and bring both lists to an estate planning attorney.
