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, so when one owner dies their share passes directly to the survivors outside of probate. Civil Code Section 683 requires the deed to expressly declare the arrangement, and small mistakes in creating, maintaining, or ending it can cost tens of thousands of dollars in taxes or trigger disputes that end up in court. Before you sign anything, it helps to know exactly what you are agreeing to.
What Makes a Joint Tenancy Valid
California courts require four conditions, called the unities, to exist at the moment the joint tenancy is created. If any one of them is missing or breaks later, the arrangement converts to a tenancy in common, and the survivorship right disappears.
- Unity of time: every joint tenant receives their interest at the same moment.
- Unity of title: all interests come from a single deed, will, or other transfer document.
- Unity of interest: each tenant holds an equal share. Two people each own half; three each own a third.
- Unity of possession: every tenant has the right to use and occupy the entire property, not a specific portion.
The deed has to do the work of establishing all this. It must name the parties, describe the property, use operative words of conveyance, and state that the grantees take title “as joint tenants.”1California Legislative Information. California Code Civil Code Section 683 Language like “with right of survivorship” alone, without the words “joint tenancy,” has produced litigation, so most real estate attorneys use the full phrase “as joint tenants with right of survivorship.” If the deed does not specify joint tenancy, California presumes the co-owners hold as tenants in common instead.
California does allow a sole owner to create a joint tenancy by deeding the property to themselves and another person in a single instrument, which is treated as satisfying the unity requirements. Every grantor must sign and have the signature notarized, and the deed must then be recorded with the county recorder where the property sits. Recording protects the grantees against later competing claims by putting the public on notice.2Board of Equalization, California. Property Ownership and Deed Recording
How the Right of Survivorship Works
When one joint tenant dies, that person’s share does not pass through a will and does not go to their heirs. The deceased tenant’s interest simply ends, and the surviving tenants’ ownership expands to fill the whole property. A will cannot override this. If a joint tenant wants to leave their share to someone else after death, they have to sever the joint tenancy while they are still alive.
Clearing title after a death is usually straightforward. The surviving tenant records an affidavit of death along with a certified copy of the death certificate, and no probate proceeding is needed. Avoiding probate is one of the main reasons people use joint tenancy in the first place.
Equal Shares and Shared Costs
Because each joint tenant owns an equal, undivided interest, contributions to the purchase price do not translate into proportional ownership. Someone who put up 80 percent of the down payment and named another person as joint tenant does not own 80 percent of the property. They own half. Everyone also has the right to occupy and use the entire property, not a specific room or section.
Financial responsibilities follow the same logic. Property taxes, mortgage payments, insurance, and maintenance are shared equally in principle. A tenant who pays more than their share may have a right to reimbursement, but enforcing it usually requires a lawsuit, and success depends on detailed records of who paid what.
Joint Bank Accounts in California
Joint tenancy is not limited to real estate. Under Probate Code Section 5302, money left in a joint bank account when one owner dies belongs to the surviving owner unless there is clear and convincing evidence of a different intent.3California Legislative Information. California Probate Code Section 5302 That is a high standard, so adding a name to an account is not a casual step.
A common example: a parent adds an adult child to a bank account so the child can help pay bills. If the parent dies, the child legally owns the entire account, even if the parent’s will directs the funds elsewhere. Other heirs would have to prove the parent never intended a true joint tenancy, and the evidence would need to meet the clear and convincing standard.
How to Sever a Joint Tenancy
Any joint tenant can sever their own interest without the consent, or even the knowledge, of the others. Civil Code Section 683.2 recognizes two methods for real property:4California Legislative Information. California Code Civil Code Section 683.2
- Deeding the interest to a third party, including a strawman transfer where the interest is deeded out and then deeded back.
- Signing a written declaration of severance, which can name the tenant as both transferor and transferee or simply state that the joint tenancy is severed.
The trap is recording. 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. A narrow deathbed exception applies: if the document is signed and notarized within three days before death, it can be recorded up to seven days after death and still cut off survivorship.
Once severed, the former joint tenant becomes a tenant in common with the others. They lose the right of survivorship and gain the ability to sell, gift, or bequeath their share. The remaining joint tenants continue to hold their own interests as joint tenants with each other. A written agreement can restrict severance between the parties, 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.
Community Property With Right of Survivorship for Married Couples
Married couples in California usually have a better option than joint tenancy for real estate. Community property with right of survivorship, created by Civil Code Section 682.1, gives the surviving spouse the property outside of probate just like joint tenancy does.5California Legislative Information. California Code Civil Code Section 682.1 The difference is the tax treatment.
With joint tenancy, only the deceased spouse’s half of the property gets a stepped-up tax basis to fair market value at death. 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 when one spouse dies. The survivor’s basis becomes $750,000 (their original $150,000 plus the stepped-up $600,000 half). Selling immediately for $1.2 million produces $450,000 in potential capital gains.
Community property with right of survivorship gets a full step-up on the entire property under federal tax law. In the same example, the survivor’s basis becomes the full $1.2 million, and an immediate sale produces no capital gains. In California’s real estate market, the difference routinely runs into six figures. The deed simply needs to state the property is held “as community property with right of survivorship.”
Tax Consequences You Should Expect
Stepped-Up Basis for Non-Spouses
When non-spousal joint tenants (siblings, a parent and child, business partners) hold property together, only the deceased tenant’s share receives a stepped-up basis. The survivor’s own share keeps its original cost basis.6Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent For a two-person joint tenancy on property originally bought for $400,000 and worth $1 million at death, the survivor’s new basis is $700,000. A sale for $1 million produces $300,000 in taxable gain.
Gift Tax When Adding a Joint Tenant
Adding someone to a deed as a joint tenant counts as a gift under federal tax law. If you paid the full purchase price and title now shows you and another person as joint tenants, you have given that person half the property’s value.7eCFR. 26 CFR 25.2511-1 – Transfers in General For 2026, gifts exceeding $19,000 per recipient in a year require a gift tax return, though no tax is due until the donor’s lifetime giving passes the $15 million exemption.8Internal Revenue Service. Whats New – Estate and Gift Tax Adding a spouse generally does not require a return because of the unlimited marital deduction, but adding a child, sibling, or friend to a deed where the gifted half exceeds $38,000 triggers a filing requirement.
Estate Tax Inclusion
Federal estate tax rules treat spouses and non-spouses differently. For married joint tenants, 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 entire property is presumed to be in the deceased’s estate unless the survivor can prove they contributed to the purchase; if they can, only the deceased’s proportional contribution is included.9Office of the Law Revision Counsel. 26 U.S. Code 2040 – Joint Interests A parent who pays for a home and then adds an adult child as a joint tenant will have 100 percent of the value counted in their own estate at death.
Creditors, Mortgages, and Death Scenarios
A creditor holding a judgment against one joint tenant can record a lien against that tenant’s interest and force a sale, 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 terminates at death, the lien dies 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
Mortgages are a common worry, and federal law resolves it. The Garn-St. Germain Act blocks lenders from calling a loan due on residential property of up to four dwelling units when ownership changes because a joint tenant died.11Office of the Law Revision Counsel. 12 U.S. Code 1701j-3 – Preemption of Due-on-Sale Prohibitions The surviving tenant keeps making payments under the existing terms. That protection does not cover voluntary transfers to a new owner during life. A severance that brings in a stranger to the loan can trigger the due-on-sale clause, so check with the lender first.
When joint tenants cannot agree on what to do with the property, any co-owner can file a partition action to force a sale or physical division.12California Legislative Information. California Code of Civil Procedure Section 872.210 The court usually orders an auction and divides the proceeds according to each owner’s interest, though it can adjust the distribution for unequal contributions such as mortgage payments made by only one tenant. Partition litigation is slow and expensive, and everyone typically nets less than a voluntary sale would produce.
If joint tenants die together and the order of death cannot be established by clear and convincing evidence, Probate Code Section 220 treats each person as having survived the other for the purpose of distributing their own property.13California Legislative Information. California Probate Code Section 220 Each tenant’s half then passes through their own estate rather than to the co-tenant. A deed or separate agreement can override this default with a specific survivorship provision.
