Community Property With Right of Survivorship vs. Joint Tenancy

Short answer: If you’re married and hold your California home in joint tenancy, you may be signing your surviving spouse up for a capital-gains bill they never needed to owe. Community property with right of survivorship (CPWROS, Civil Code §682.1) passes to the survivor automatically, exactly like joint tenancy — but because it’s community property, both halves of the home get a full basis step-up at the first death under IRC §1014(b)(6). Joint tenancy steps up only the deceased spouse’s half. On a long-held Ventura County house, that single word on the deed can be the difference between a six-figure taxable gain and zero.

The double step-up, in real dollars

Say a Thousand Oaks couple bought their house in the 1990s for $300,000, and it’s worth $1.3 million when the first spouse dies. The survivor sells. Watch the title wording work:

• Joint tenancy: only the deceased spouse’s half steps up to date-of-death value. The survivor’s basis is their own original half ($150,000) plus the stepped-up half ($650,000) — $800,000 total. Sell for $1.3 million and there’s a $500,000 gain. Even after the survivor’s $250,000 home-sale exclusion under IRC §121, roughly $250,000 is taxable.
• CPWROS: the house is community property, so under IRC §1014(b)(6) both halves step up. The survivor’s basis is the full $1.3 million. Sell for $1.3 million and the taxable gain is roughly zero.

Same house, same couple, same sale — the only difference is the title wording. California adds nothing either way (no state estate or gift tax), and the federal estate tax is out of the picture for most families at a $15 million per-person exemption. For most married Californians, basis is the whole tax game, and joint tenancy loses it.

How CPWROS works

Civil Code §682.1 created the hybrid: community property that’s “expressly declared in the transfer document to be community property with right of survivorship.” It’s available for instruments taking effect on or after July 1, 2001. At the first death, the property passes to the surviving spouse without probate and without administration — the same clean handoff joint tenancy gives you. And like a joint tenancy, either spouse can sever the survivorship feature unilaterally under the §683.2 recording rules.

So you give up nothing joint tenancy offered — automatic transfer, severability — and you pick up the community-property tax treatment. For a married couple choosing between these two boxes on a deed, CPWROS wins almost every time.

Already joint tenants? The In re Brace wrinkle

Here’s where it gets interesting for couples who titled their home as joint tenants decades ago. In In re Brace (2020) 9 Cal.5th 903, the California Supreme Court held that for property acquired with community funds during marriage (on or after January 1, 1975), the Family Code §760 community-property presumption beats the form-of-title presumption — a joint tenancy deed alone doesn’t transmute community property into anything else. In plain English: a lot of “joint tenancy” homes in California may really be community property under state law.

Does that mean a surviving spouse with a JT deed can claim the double step-up anyway? Federal basis treatment follows the property’s community character — but expect to have to prove it, years later, with records from a purchase thirty years ago. That’s a fight you avoid entirely by fixing the title now, while both spouses can sign. Retitling between spouses triggers no reassessment: interspousal transfers are excluded under Rev. & Tax. Code §63, regardless of how title was held before.

Why the trust usually beats both

Now the part the deed-form comparison hides. Both joint tenancy and CPWROS share the same two structural problems:

• They only postpone probate. Survivorship works beautifully at the first death. At the second death, the house is sitting in the survivor’s name alone, and there’s no survivorship left. Without other planning, it goes through probate then.
• They override your trust and your will. Title with a right of survivorship is a nonprobate transfer — it passes by operation of law, no matter what your estate plan says. A beautifully drafted trust does nothing for a house that’s titled to pass by survivorship outside it.

A revocable living trust holding the home as community property gets you all of it: the double step-up (community character is preserved in the trust), no probate at the first death, no probate at the second death, and instructions for incapacity and for the kids. That’s why, for most married homeowners, the real answer isn’t “CPWROS instead of joint tenancy” — it’s the trust. We walk through the broader comparison in joint tenancy vs. trust, and the tax mechanics at the second generation in capital gains on an inherited home.

What is community property with right of survivorship in California?

It’s a way for spouses (or registered domestic partners) to hold title, created by Civil Code §682.1 for instruments on or after July 1, 2001. The deed must expressly declare the property “community property with right of survivorship.” At the first death the survivor takes the whole property automatically, without probate — like joint tenancy — but the property keeps its community-property character for tax purposes.

Why does CPWROS get a bigger step-up in basis than joint tenancy?

Because of IRC §1014(b)(6), a rule specific to community property: when the first spouse dies, both halves of a community asset — the decedent’s and the survivor’s — reset to fair market value. Joint tenancy property held by spouses gets a step-up only on the deceased spouse’s half. On an appreciated home, the difference is the survivor’s entire built-in gain on their own half.

Does a joint tenancy deed mean our house isn’t community property?

Not necessarily. Under In re Brace (2020) 9 Cal.5th 903, property bought with community funds during marriage is presumed community property even if the deed says joint tenancy — the deed alone doesn’t change its character. But for the tax benefit you’d have to prove community character after the fact. Retitling now is cleaner, and interspousal transfers are never reassessed (Rev. & Tax. Code §63).

Does CPWROS avoid probate completely?

Only at the first death. The survivor takes without administration, but the property then sits in the survivor’s sole name with no survivorship feature left — so at the second death it heads to probate unless the survivor has a trust or other plan. Survivorship title postpones probate; it doesn’t eliminate it.

Can one spouse undo the right of survivorship?

Yes. CPWROS is severable unilaterally, the same way a joint tenancy is, under the Civil Code §683.2 mechanics: as a general rule the severance must be recorded before death — or signed at least three days before death and recorded within seven days after — to defeat the survivorship. That’s a feature, not a bug: neither spouse is locked in.

Should married couples use CPWROS or a living trust?

If the only choice is between the two survivorship deed forms, CPWROS beats joint tenancy for spouses — same convenience, better basis. But a living trust holding the home as community property delivers the double step-up and skips probate at both deaths and handles incapacity. For most married homeowners the trust is the better tool.

The bottom line

Joint tenancy is the default habit of California deeds, and for married couples it’s usually the wrong one — it throws away half of a tax benefit the law hands community property for free. If you and your spouse hold your home as joint tenants, the fix is a straightforward retitle: to CPWROS at minimum, or better, into your living trust with community character intact. No reassessment, no gift tax, no downside worth naming. If you want a quick read on how your home is actually titled and what the cleanest fix looks like, Talk to Eric.
