In California, joint tenancy is a form of co-ownership in which two or more people hold equal, undivided shares of the same property with an automatic right of survivorship: when one owner dies, their share passes to the surviving owners by operation of law, outside probate. Civil Code Section 683 requires the deed to say so expressly, and the choice carries tax and creditor consequences that often favor a different form of ownership, particularly for married couples.
The Four Unities Behind a Valid Joint Tenancy
California courts recognize a joint tenancy only when four conditions, called the unities, exist at the moment title is created. Break any one of them and the arrangement collapses into a tenancy in common, which has no survivorship right.
- Unity of time: every joint tenant receives their interest at the same moment.
- Unity of title: all interests come through the same deed or transfer document.
- Unity of interest: each tenant holds an equal share. Two owners means 50/50; three means thirds.
- Unity of possession: every tenant has the right to use the whole property, not a specific portion of it.
Equal shares is the point most buyers miss. Even if you put up 80% of the purchase price, in a joint tenancy you still own exactly the same share as every other named tenant. If the deed does not state “joint tenancy,” California presumes a tenancy in common instead.1California Legislative Information. California Code Civil Code Section 683
Creating a California Joint Tenancy Deed
The deed does the work. It must identify the parties, describe the property accurately, use operative words of conveyance such as “hereby grants,” and expressly state that the grantees take title “as joint tenants.”1California Legislative Information. California Code Civil Code Section 683 Vague language like “with right of survivorship” without the words “joint tenancy” has produced litigation, so most practitioners use the full phrase “as joint tenants with right of survivorship.”
Every grantor signs, and the signature must be acknowledged before a notary. California notaries can charge up to $15 per signature.2Board of Equalization, California. Property Ownership and Deed Recording
The notarized deed then needs to be recorded with the county recorder where the property sits. Recording is not required for the deed to be valid between the parties, but it protects the grantees against later claims by putting the public on notice. Base recording fees in California generally run $15 to $75, with surcharges for programs that vary by county.2Board of Equalization, California. Property Ownership and Deed Recording Skipping the recording step is where owners run into trouble, especially if someone dies before the deed reaches the county.
California also allows an owner to create a joint tenancy by transferring property to themselves and another person through a single deed, which satisfies the unity requirements even though the original owner already held title.1California Legislative Information. California Code Civil Code Section 683
What Happens When a Joint Tenant Dies
Survivorship is the whole reason most people choose this form of ownership. When one joint tenant dies, their interest ends and the surviving tenants’ shares expand to absorb it. The survivor does not inherit in the traditional sense, and a will cannot redirect the share. A joint tenant who wants their portion to go to a child, a trust, or anyone other than the co-owners has to sever the tenancy while alive.
To clear title after a death, the surviving tenant typically records an affidavit of death with a certified copy of the death certificate. The whole exercise is faster and cheaper than probate, which is the practical appeal.
Shared Rights and Shared Costs
Because each tenant holds an equal, undivided interest, no one has an exclusive claim to a particular room, section, or acre. Every tenant may use the entire property. Taxes, mortgage payments, insurance, and maintenance are shared equally in principle, and a tenant who pays more than their share may have a right to reimbursement, though enforcing it usually requires litigation. Keep records.
If one tenant physically locks another out, that is an “ouster” under California law, and the excluded tenant can sue for the reasonable rental value of their share for the full exclusion period.3California Law Revision Commission. Joint Tenancy – Resolution of Disputes Where Property
Why Married Couples Should Look at Community Property With Right of Survivorship
For spouses, joint tenancy is almost always the wrong choice for real estate. Civil Code Section 682.1 lets California couples hold property as community property with right of survivorship, which also avoids probate but delivers a far better tax result.4California Legislative Information. California Code Civil Code Section 682.1
The difference is in the basis step-up. When joint tenancy property passes to a surviving spouse, only the deceased spouse’s half is stepped up to current fair market value. The survivor’s half keeps its original cost basis. Say a couple bought a home for $300,000 and it is worth $1.2 million at the first spouse’s death. The surviving spouse’s basis becomes $750,000: their original $150,000 plus the stepped-up $600,000 half. Selling at $1.2 million produces about $450,000 of potential capital gain.
With community property, federal law gives a full step-up on the entire property. In the same example, the survivor’s basis becomes the full $1.2 million, and an immediate sale produces no capital gain. In California’s market, that difference routinely saves surviving spouses six figures. The deed just needs to state that the property is held “as community property with right of survivorship,” and both spouses should sign or initial accepting that designation.
Tax Consequences for Non-Spouses
Basis Step-Up Is Only Partial
For non-spousal joint tenants, such as siblings, a parent and child, or business partners, the surviving tenant gets a stepped-up basis only on the deceased tenant’s share.5Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent If two tenants bought at $400,000 and the property is worth $1 million at death, the survivor’s new basis is $700,000, so an immediate sale leaves $300,000 of taxable gain.
Adding Someone to a Deed Is a Gift
Putting another person on a deed as a joint tenant transfers half the property’s value to them, and federal gift tax rules apply.6eCFR. 26 CFR 25.2511-1 – Transfers in General For 2026, gifts over $19,000 per recipient per year require a gift tax return, though no tax is due until the lifetime exemption of $15 million is used up.7Internal Revenue Service. Whats New – Estate and Gift Tax Spouses are generally covered by the unlimited marital deduction, so no return is needed there. Adding a child, sibling, or friend to a deed where the gifted half exceeds $19,000 triggers a filing.
Estate Tax Inclusion
For spouses, exactly half the property’s value is included in the deceased spouse’s taxable estate regardless of who paid. For non-spousal joint tenants, the whole property’s value is presumed to be in the deceased’s estate unless the survivor can prove they contributed to the purchase; to the extent they contributed, that portion comes out.8Office of the Law Revision Counsel. 26 U.S. Code 2040 – Joint Interests So if a parent paid for the whole property and later added a child as a joint tenant, 100% of the value is in the parent’s estate at death. The federal exemption for 2026 is $15 million per person, which keeps most estates out of range, but California values can climb into that territory faster than people expect.7Internal Revenue Service.

How to Sever a Joint Tenancy
Any joint tenant can end their participation unilaterally, without notice to the others. Civil Code Section 683.2 recognizes two methods for real property.9California Legislative Information. California Code Civil Code Section 683.2
- Deed to a third party. The tenant signs and delivers a deed transferring their interest. This includes “strawman” transactions where the interest is deeded out and then deeded back to destroy the unities of time and title.
- Written declaration. A signed instrument stating that the joint tenancy is severed as to the signer’s interest, which can take the form of a deed naming the tenant as both transferor and transferee.
The recording trap matters more than the method. A severance is not effective against the other tenants’ survivorship rights unless the document is recorded in the county where the property sits before the severing tenant dies. There is one narrow exception: if the severance is signed and notarized within three days before death, it can be recorded up to seven days after death and still work.9California Legislative Information. California Code Civil Code Section 683.2
Once severed, the former joint tenant becomes a tenant in common with the remaining owners. They lose the right of survivorship and can sell, gift, or will their share freely. The remaining tenants continue as joint tenants with each other. A written agreement among joint tenants can restrict severance, but a severance made in violation of such an agreement is still valid against a third-party buyer who did not know about the restriction.9California Legislative Information. California Code Civil Code Section 683.2
Creditor Claims and the Survivorship Race
A creditor holding a judgment against one joint tenant can record a lien on that tenant’s interest and force a sale of that interest, which severs the joint tenancy. But if the creditor sits on the lien and the debtor dies first, the lien disappears. California courts have held that the lien attaches only to the debtor’s interest, and because that interest ends at death, the lien ends with it. The surviving joint tenant takes the property free of the debt.10California Law Revision Commission. Enforcement of Judgments – Effect on Lien on Joint Tenancy Property
So creditors with judgments against a joint tenant have an incentive to act quickly. For debtors, survivorship offers a measure of asset protection, but a weak one, since the creditor can force a sale any time the debtor is alive.
When Co-Owners Can’t Agree: Partition
If joint tenants cannot agree on what to do with the property, any co-owner can file a partition action asking the court to force a sale or physical division.11California Legislative Information. California Code of Civil Procedure Section 872.210 Most residential property gets sold at auction and the proceeds split; rural land can sometimes be divided into separate parcels. Courts may also adjust the distribution to reimburse a tenant who paid more than their share of the mortgage, taxes, or improvements, but the burden is on that tenant to prove the amounts with records.
Partition cases are slow and expensive. Legal fees, appraisal costs, and auction inefficiency usually leave everyone with less than a voluntary sale would have produced. Mediation to negotiate a buyout, a voluntary sale, or a written co-ownership agreement is almost always worth trying first.
The Mortgage Stays Put When a Joint Tenant Dies
Most mortgages contain a due-on-sale clause that lets the lender demand full repayment when ownership changes. The Garn-St. Germain Act blocks lenders from invoking that clause on residential property of up to four dwelling units when the transfer happens because a joint tenant died.12Office of the Law Revision Counsel. 12 U.S. Code 1701j-3 – Preemption of Due-on-Sale Prohibitions The surviving tenant keeps paying under the existing loan.
That protection does not reach voluntary transfers between living owners. A joint tenant who sells or transfers their interest to a new, outside owner can trigger the due-on-sale clause. Clear any severance that brings in a new owner with the lender first.
Simultaneous Death of Joint Tenants
Survivorship depends on one tenant outliving the other, so a simultaneous death creates a problem. Under Probate Code Section 220, when the order of death cannot be established by clear and convincing evidence, each person’s property is distributed as if that person had survived the other.13California Legislative Information. California Probate Code Section 220 For joint tenancy property, that means each tenant’s half passes through their own estate. Two siblings who held a home in joint tenancy and died together in an accident, with no evidence of order, would each have their half go to their respective heirs through probate. Joint tenants can override this result with a specific survivorship provision in the deed or a separate agreement that spells out a different distribution.
