Most people facing this question are standing in a kitchen with a stack of papers: a surviving spouse whose name is on the deed beside a partner's, an adult child who was added to a parent's title years ago, a sibling who shared a house with a brother. Other relatives are asking what happens to the house, and the honest first answer depends on one line of the deed. This page walks through what that line means, what the survivor records, and what follows for property tax and income tax.
What Joint Tenancy Means Under California Law
A joint tenancy is a way for two or more people to own the same property in equal shares, with each owner's interest ending at death and the survivors keeping the whole. Civil Code section 683 defines a joint interest as one "owned by two or more persons in equal shares, by a title created by a single will or transfer, when expressly declared in the will or transfer to be a joint tenancy," and it lists other transfers that can create one, including a transfer from a sole owner to that owner and others when expressly declared in the transfer to be a joint tenancy. The words "expressly declared" matter: for a house, the will or deed that creates the interest has to say joint tenancy.
The right of survivorship is the feature that makes joint tenancy different. It means that when one owner dies, that owner's share does not pass through a will or probate; the surviving owner or owners simply keep the property.
A tenancy in common is different. Each owner holds a share that passes through that owner's own estate, by will or by the rules for people who die without one, so there is no survivorship.
Spouses and registered domestic partners have further choices, including community property and community property with right of survivorship. Under Civil Code section 682.1, community property "expressly declared in the transfer document to be community property with right of survivorship" passes to the survivor "without administration," following "the same procedures, as property held in joint tenancy," for instruments created on or after July 1, 2001. These forms carry different tax results, discussed below.
What Happens to the Property When a Joint Tenant Dies
In practical terms, nothing has to be inherited. The deceased owner's interest ends at death, and the survivor already holds the entire property. Because of this, a joint tenancy interest is not something a will can give away, and the property does not go through probate merely because of that interest. Probate Code section 13050 confirms the point for California's simplified procedures: property the decedent "held ... as a joint tenant" is excluded when figuring the size of the estate.
The number of survivors shapes the result. Take a hypothetical three-person joint tenancy: when one owner dies, the two who remain continue as joint tenants with each other, in equal shares, with survivorship still in place. When only one owner survives, that person owns the property alone.
The family still has paperwork. Title records keep showing the deceased owner's name until a document is recorded, which is the subject of the next section. The broader picture of what happens to a house after a death depends on how title was held.
One caution belongs here. A joint tenancy can be severed during life, and Civil Code section 682.1 refers to "the procedures by which a joint tenancy may be severed." If that happened before the death, survivorship may not apply, and a title review answers the question.
The Affidavit of Death of Joint Tenant: Clearing the Record Title
The affidavit of death of joint tenant is the document that tells the public record a joint tenant has died, so the survivor's ownership shows on title. It is recorded with the county recorder, not filed with a court.
Probate Code section 210 provides that when "title to real property is affected by the death of a person, any person may record in the county in which the property is located" an "affidavit of death executed by a person having knowledge of the facts." The statute requires that the affidavit "include a particular description of the real property and an attested or certified copy of a record of the death." Section 210 also allows a certified copy of a court order determining the fact of death to be recorded instead.
In practice, the particular description is usually the legal description copied from the existing deed, and the record of death is a certified death certificate. Once both are recorded, the survivor or survivors appear on record as owners.
Each county recorder sets its own recording fees and cover-sheet requirements. The recorder's office in the county where the property sits states its current fees, and a title company or real estate attorney can confirm signing and notary requirements.
Change of Ownership and Property Tax Reassessment
Property tax works on its own track. Recording the affidavit does not settle whether the county assessor revalues the property.
The State Board of Equalization's Change in Ownership FAQ says that deeds "and certain other recorded documents must be accompanied by a Preliminary Change of Ownership Report (PCOR) at the time of the recording," and that the recorder "may charge a $20 fee" when the PCOR is filed later. The PCOR asks, among other things, about "possible exclusions from reassessment."
That same page lists exclusions relevant to a joint tenant's death. Transfers "upon the death of a spouse" and, on or after January 1, 2006, upon the death of a registered domestic partner are automatically excluded. A surviving cotenant may qualify for a cotenancy exclusion by filing an affidavit with the assessor, where the two cotenants together owned 100 percent and, for the year before the death, both were on title and continuously lived in the property.
For parent-child transfers, and grandparent-grandchild transfers where the grandchild's parents have died, on or after February 16, 2021, Rev. & Tax. Code section 63.2 governs. The home must have been the transferor's principal residence and become the transferee's principal residence within one year, the transferee must file for the homeowners' or disabled veterans' exemption within a year, and a claim must be filed with the assessor. The Board's Proposition 19 page describes the value limit as current taxable value plus $1,000,000, "as biennially adjusted," and says a rental home would not qualify. The deadlines and value limit appear on the guide to California property tax on inherited property.
The county assessor's office decides whether an exclusion applies and takes the claim.
Federal Income Tax Basis After a Joint Tenant Dies
Basis is the starting number used to figure gain when property is sold, and a death can reset it. Under 26 U.S.C. § 1014(a), the basis of property acquired from a decedent is generally "the fair market value of the property at the date of the decedent's death," with alternatives where the estate makes certain valuation elections. That reset is called a step-up in basis.
For jointly held property, the rule generally reaches what passed from the person who died, not the survivor's own share, so in many joint tenancies only the deceased owner's portion is reset. How much counts as passing from the decedent depends on facts such as who contributed to the purchase and whether the owners were married.
Community property is treated differently. Under 26 U.S.C. § 1014(b)(6), the surviving spouse's one-half share of community property is also treated as acquired from the decedent, if at least half of the whole community interest was includible in the decedent's gross estate. That is one reason the form of title can matter years later, when a survivor sells and the reset basis reduces the gain on capital gains on inherited property.
A CPA, an enrolled agent or a tax attorney figures the adjusted basis and reviews what a future sale would mean.
When Joint Tenancy and Probate Intersect
Survivorship avoids probate only when it is still in place at the death. If a joint tenant severed the joint tenancy beforehand, such as by transferring an interest to someone else, the owners generally become tenants in common, and the deceased's share becomes part of that person's estate.
When every joint tenant has died, the property passes through the estate of the last survivor, and that estate may need probate or a simplified procedure. If the last survivor left no will, Probate Code section 8461 sets the order of who may be appointed administrator, beginning with a surviving spouse or domestic partner, then children, then grandchildren, and continuing through other relatives to creditors and "any other person."
Some situations turn on facts that need an attorney's reading. When owners die together and it cannot be shown who survived whom, special rules apply, and a probate attorney handles that question. Whether the deceased owner's debts can reach the property is also a separate question for a probate attorney.
Where co-owners or heirs disagree about the property, that is a contested matter handled by an attorney who litigates trust and probate cases. A partition action is the court proceeding used to resolve co-ownership disputes. This page does not explain contested matters or how to bring one.
Joint Tenancy Compared to Other Ways Californians Hold Title Together
The form of title affects three things families most often need to understand: whether probate is needed, whether property tax is reassessed, and what income tax basis the survivor ends up with. These are the common forms of shared ownership:
- Tenancy in common. There is no survivorship, so each share passes through its owner's will or intestate succession and may need probate.
- Community property. This form is available to spouses and registered domestic partners, and what happens at death depends on the will and the facts. A surviving spouse may use the spousal or domestic partner property petition under Probate Code section 13650, which asks the court for an order that administration is not necessary because property is "passing to the surviving spouse." The Judicial Council's DE-221 Spousal or Domestic Partner Property Petition is the form for that request. Under Probate Code section 13540, generally after 40 days from the death, a surviving spouse has full power to sell or otherwise deal with community or quasi-community real property.
- Community property with right of survivorship. This form passes to the survivor like a joint tenancy and can carry the community property basis treatment.
- Revocable living trust. Property in the trust's name passes under the trust's terms, and a successor trustee steps in instead of a probate court.
- Transfer on death deed. This deed names someone to receive the property at the owner's death.
Bank accounts follow similar logic. Under Probate Code section 5302, money left in a joint account generally belongs to the surviving party unless there is clear and convincing evidence of a different intent, and a will cannot change that.
The Judicial Council's guide Inventory and estimate property value notes that "Deeds are public records and are available at the County Recorder's Office." Property that may transfer outside probate covers more forms. How to create or change a will or trust is estate planning, which this page does not cover.
Steps the Surviving Joint Tenant Typically Takes
The sections above explain each piece; this checklist gathers them in the order they tend to come up. A surviving joint tenant often handles them while also answering questions from other relatives.
- Order certified copies of the death certificate. Recording and many notifications each call for a certified copy.
- Pull the current deed. The deed shows whether title says joint tenancy and supplies the legal description.
- Prepare the affidavit of death. A title company or real estate attorney commonly prepares it to meet Probate Code section 210 and county requirements.
- Record the affidavit with the county recorder. It goes to the recorder in the county where the property is located, with the certified death record attached.
- Submit the Preliminary Change of Ownership Report with the recording. The State Board of Equalization's page says the PCOR accompanies recorded documents.
- Contact the county assessor about exclusions. The assessor's office takes exclusion claims and decides eligibility.
- Notify the mortgage servicer. For homes with fewer than five dwelling units, 12 U.S.C. § 1701j-3(d) bars a lender from enforcing a due-on-sale clause upon "a transfer by devise, descent, or operation of law on the death of a joint tenant" or "a transfer to a relative resulting from the death of a borrower."
- Update the homeowner's insurance. The policy should reflect the survivor as owner.
- Ask a tax professional about basis. A CPA, enrolled agent or tax attorney can document the date-of-death value.
The State Board of Equalization's page also lists timing for a change in ownership resulting from a death: within 150 days of the date of death when there is no probate, or at the same time the inventory and appraisal is filed when the estate is probated. After recording, the survivor who holds title decides whether to keep the property or sell it. The selling process is a separate subject.
