Family Trust vs Living Trust in California

The two phrases show up together in search because attorneys, banks, and family members use them loosely. Nothing in California law defines a “family trust,” so the label alone tells you very little. This page covers what the words usually mean and the differences that change what happens to your family and your house.

Is a family trust the same as a living trust?

In most California estate plans, yes. A living trust is a trust you create while you’re alive, and a couple’s plan is often titled “The Smith Family Trust.” The document is a revocable living trust with a family name on it.

The confusion comes from a second use of the phrase. In a plan built around an A/B structure, the “family trust” is the sub-trust that holds the deceased spouse’s share after the first death. That’s a piece of a living trust, not a different kind of trust you shop for separately.

What do people mean when they say “family trust”?

Three things, and only the first two are common in California.

1. A revocable living trust for a family. Most people who say “family trust” mean this. You keep control and can change it. See what a living trust is in California.
2. The A/B or bypass trust. After the first spouse dies, the joint trust divides. The survivor’s share stays revocable. The deceased spouse’s share becomes irrevocable and is often called the family trust, Trust B, or the bypass trust.
3. An irrevocable trust for family wealth. A trust funded during life that the maker can’t easily take back, used for tax or protection goals. It’s a different tool and sits at the other end of the spectrum.

Revocable or irrevocable: which one matters most?

This choice is the difference that changes the outcome. A California trust is revocable unless the instrument expressly makes it irrevocable (Prob. Code § 15400), so a standard living trust lets you change or cancel it while you’re alive.

An irrevocable trust is the opposite: you give up the right to take property back. That makes it useful for certain tax and protection goals, and a poor fit for a family home you still live in. A revocable trust also becomes irrevocable at the death of the person who made it, and the trustee then has to serve notice on beneficiaries and heirs (Prob. Code § 16061.7). The tradeoffs are laid out in revocable vs irrevocable trusts in California.

Should a married couple have one joint trust or two separate trusts?

Most married couples use one joint trust. It’s simpler to fund, and California treats community property in a revocable trust as staying community property during the marriage, as long as the trust is revocable as to that property and can be modified only with both spouses joining or consenting (Fam. Code § 761). Community property is what a spouse acquires during marriage while living in California (Fam. Code § 760).

Separate trusts make sense in blended families. They also make sense when one spouse has substantial separate property, or when each spouse wants different beneficiaries. The cost is more paperwork and a more careful sorting of what belongs to whom. The community property rules are covered in community property and estate planning in California.

Do I need an A/B trust in California?

Most California couples don’t need one for tax reasons. The federal estate tax exemption is $15,000,000 per person in 2026 (26 U.S.C. § 2010(c)), and California has no estate or inheritance tax.

A/B structures were designed to use both spouses’ exemptions before portability existed. Portability now lets a surviving spouse claim a deceased spouse’s unused exclusion, but only if the executor files an estate tax return and makes the election on a timely return (26 U.S.C. § 2010(c)(5)(A)). A/B splitting still has a place where the first spouse wants to settle who gets their share, as in a second marriage, or where combined assets approach the federal number. I go through this in whether you still need an A/B trust, and there’s a longer A/B trust guide.

What are the disadvantages of a revocable living trust in California?

There are six real ones. A living trust is worth it for most homeowners, and it still has costs that sales pages skip.

1. It costs more up front than a will. A trust-based plan takes more drafting and more follow-through. My flat fee is $4,900, and the fee schedule is on the fees page. Compare it with what a living trust costs in California.
2. You have to fund it. The trust only controls what’s titled in it. The house needs a recorded deed, and accounts need to be retitled. When a house is left out, the family may need a Heggstad petition under Prob. Code § 850 or a probate. The steps are in trust funding.
3. It doesn’t protect assets from your creditors. If you keep the power to revoke, the trust property is subject to claims of your creditors to the extent of that power during your lifetime (Prob. Code § 18200).
4. It doesn’t save income tax while you’re alive. The grantor is treated as the owner of any portion of a trust where the power to revest title in the grantor is exercisable by the grantor or a non-adverse party (26 U.S.C. § 676(a)). In practice you report everything on your own return, and a living trust doesn’t file a separate tax return during your life.
5. It doesn’t end the paperwork at death. It avoids probate for what it holds, and the successor trustee still has duties: notify beneficiaries and heirs within 60 days (Prob. Code § 16061.7), and account to beneficiaries at least annually (Prob. Code § 16062). See what a successor trustee does.
6. It needs upkeep. A trust drafted years ago may not match your family, your property, or the current law. New assets that never make it into the trust are the most common gap.

The property tax point runs the other direction, so it belongs on the plus side. Transferring your home to your own revocable trust isn’t a change in ownership that triggers reassessment while you’re the trustor and the trust is revocable (Rev. & Tax. Code § 62(d)).

What is the downside to a living trust, in one paragraph?

The downside is work and expectations. You pay for drafting, you have to retitle assets, and you may believe the trust does things it doesn’t do: it doesn’t shield you from creditors, cut your taxes while you live, or stop relatives from fighting. For a homeowner with a house worth more than the small estate limits, the work is usually cheaper than the probate it avoids. For a renter with a bank account and a beneficiary designation, a will and a few forms may be enough. The statutory ceiling for a small estate affidavit is $208,850 for deaths on or after April 1, 2025, and a primary residence petition works up to $750,000 for those deaths, so the math turns on what you own. My page on the pros and cons of trusts for California families takes you through the decision.

A quick way to decide

Your situation	What usually fits
Married, first marriage, home and savings under the federal exemption	One joint revocable living trust, no A/B split.
Second marriage, children from a prior marriage	A joint or separate trust that becomes irrevocable at the first death and locks in the deceased spouse’s share.
Single, owns a home	A single revocable living trust.
Wants creditor protection or Medi-Cal planning	A different tool. A revocable trust doesn’t do this.

Frequently asked questions

Is a family trust revocable?

Usually, yes. A California trust is revocable unless the instrument expressly says it’s irrevocable (Prob. Code § 15400). The exception is the deceased spouse’s share in an A/B plan, which becomes irrevocable at the first death.

Do I need a family trust if I already have a living trust?

Probably not. If your living trust is the family’s plan, it already is the family trust. A separate sub-trust for a deceased spouse’s share only matters in a plan built for it, and the document will say so.

Does a living trust avoid probate?

It avoids probate for property titled in the trust. Property left out may still go through probate or a Heggstad petition. Probate itself runs twelve to eighteen months on a straightforward case, in my practice.

Does a living trust avoid estate tax?

No. A revocable trust doesn’t reduce federal estate tax by itself, and California has no estate or inheritance tax to avoid. The federal exemption is $15,000,000 per person in 2026 (26 U.S.C. § 2010(c)).

Can a living trust protect my house from creditors or nursing home costs?

No. Trust property stays reachable by your creditors while you can revoke (Prob. Code § 18200). Medi-Cal planning uses different tools with different tradeoffs, and gifting has its own rules, which I cover in giving away assets to qualify for Medi-Cal.

Is a family trust the same as a trust fund?

No. “Trust fund” usually means money held for a beneficiary, often a young person or heir. A family trust in the estate planning sense is a document that holds your assets and says who gets them.

What happens to a joint trust when one spouse dies?

The trust, or the deceased spouse’s share of it, becomes irrevocable, and the successor trustee has to send the notification under Prob. Code § 16061.7 to beneficiaries and heirs. What happens to the survivor’s share depends on how the trust was written. That’s why the split is a design decision, not a default.

If you’re trying to decide between one trust and two, or whether the phrase “family trust” in a document you were handed means what you think it does, I can read the document and tell you what it does. The statutes behind all of this are collected on California living trust laws.
