To add your spouse to the house title in California, you prepare a new deed (usually an interspousal transfer deed) that transfers an interest from you to both of you, have it notarized, and record it with the county recorder’s office along with a Preliminary Change of Ownership Report. The paperwork is straightforward and inexpensive. The decisions behind it, though, reach into property taxes, estate planning, divorce, and creditor exposure, and those are worth thinking through before you sign anything.
Decide How You Will Co-Own the Property
California recognizes several forms of co-ownership, but two make sense for most married couples: joint tenancy with right of survivorship and community property with right of survivorship. Both let the surviving spouse inherit the property automatically without probate.
Joint tenancy requires equal ownership shares and must be expressly declared. Under California Civil Code Section 683, the deed has to say “joint tenancy” or the law won’t treat it as one.1California Legislative Information. California Code, CIV 683 Community property with right of survivorship works similarly and must also be expressly declared and accepted in writing by both spouses under Civil Code Section 682.1.2California Legislative Information. California Code, CIV 682.1
The practical difference shows up when one spouse dies. Community property with right of survivorship gives the survivor a full stepped-up tax basis on the entire property to its fair market value at the date of death. Joint tenancy steps up only the deceased spouse’s half; the survivor’s half keeps its original basis.3Internal Revenue Service. Publication 551 (12/2025), Basis of Assets On a home that has appreciated substantially, that difference can save the surviving spouse tens or even hundreds of thousands in capital gains tax on a later sale.
Tenancy in common is a third option, but it has no right of survivorship and rarely fits married couples adding each other to title.
Use an Interspousal Transfer Deed
California couples typically use an interspousal transfer deed rather than a quitclaim deed. Both can move title, but the interspousal transfer deed is built for married couples. It identifies the transfer as between spouses, which makes the property tax reassessment exclusion and documentary transfer tax treatment cleaner for the county assessor to process.
The deed does not change your mortgage. This is where people get tripped up. The loan is a separate contract with your lender. Adding your spouse to the deed makes them a co-owner of the property, but it does not make them liable for the loan and does not remove your obligation. Putting both names on the mortgage requires refinancing.
Information the Deed Needs
- Full legal names of the grantor (you) and the grantee (your spouse, or you and your spouse together).
- The legal description of the property, copied exactly from your current deed. This is not the street address; it usually references lot numbers, tract maps, or metes and bounds.
- The Assessor’s Parcel Number (APN), found on your property tax bill or current deed.
- An express statement of the form of co-ownership: “joint tenancy with right of survivorship” or “community property with right of survivorship.” Without that language, the law won’t presume either.
Blank deed forms are available through online legal form providers, stationery stores, and some county recorder websites. If any part of the document is unclear, a real estate attorney can prepare it for a few hundred dollars, which is money well spent when the alternative is a deed that doesn’t say what you meant.
Sign, Notarize, and Record the Deed
You sign the deed as the grantor in front of a notary public, who verifies your identity and applies an official seal. California caps notary fees by statute, so expect a modest amount per signature.
You also need to complete a Preliminary Change of Ownership Report (PCOR). California Revenue and Taxation Code Section 480.3 requires a PCOR with every recorded deed. It asks about the relationship between the parties, whether money changed hands, and the property’s intended use. If you don’t file it at recording, the recorder adds a $20 penalty and the assessor will still want the form later.4California State Board of Equalization. Preliminary Change of Ownership Report and Change in Ownership Statement
Take the notarized deed and completed PCOR to the recorder’s office in the county where the property sits. Most offices accept documents in person or by mail. Once recorded, the deed becomes public record and your spouse is on title.
What It Costs to Record
California’s base recording fee is $10 for the first page and $3 for each additional page.5California Legislative Information. California Government Code 27361 Counties add mandatory surcharges on top. The largest is the Building Homes and Jobs Act fee (SB2) at $75 per title, but that fee doesn’t apply to transfers of a residential dwelling to an owner-occupier, which covers most interspousal transfers of a primary home. Counties also add a $10 Real Estate Fraud Prevention fee and a $2 Restrictive Covenant Modification fee.
For a typical two-page interspousal deed transferring a primary residence to an owner-occupying spouse, plan on roughly $25 to $30 in recording fees with the SB2 exemption. Without the exemption, the total lands around $100. You won’t owe documentary transfer tax on an interspousal gift, because that tax applies only to transfers made for consideration, and a gift between spouses involves none.
After recording, call your homeowners insurance company to add your spouse as a named insured so coverage matches the deed. Notifying your mortgage lender in writing is optional but creates a paper trail showing the transfer falls within the federal protections described below.
Property Taxes Will Not Be Reassessed
Adding a spouse to title does not trigger a Proposition 13 reassessment. California Revenue and Taxation Code Section 63 excludes interspousal transfers from reassessment entirely, and the assessor processes the exclusion automatically when reviewing your recorded deed and PCOR. You don’t file a separate claim.6Yolo County ACE Department. Change of Ownership Your protected tax base stays where it is.
Gift Tax Depends on Your Spouse’s Citizenship
If your spouse is a U.S. citizen, the transfer is not a taxable gift. The unlimited marital deduction under Internal Revenue Code Section 2523 lets you transfer any amount of property to a U.S. citizen spouse without owing gift tax or filing a gift tax return.7Office of the Law Revision Counsel. 26 USC 2523 – Gift to Spouse
The rules change if your spouse is not a U.S. citizen. The unlimited marital deduction doesn’t apply. Instead, the transfer is subject to an annual exclusion of $194,000 for 2026.8Internal Revenue Service. Frequently Asked Questions on Gift Taxes for Nonresidents Not Citizens of the United States If the value of the interest you’re transferring (typically half the home’s fair market value) exceeds that, you’ll need to file Form 709 and may owe gift tax or use part of your lifetime exemption. For high-value California homes, that threshold is easy to cross, so plan the transfer with a tax professional first.
Your Lender Cannot Call the Loan
Most mortgages contain a due-on-sale clause that technically lets the lender demand full repayment when ownership changes. Federal law blocks lenders from enforcing that clause when you add a spouse to title. The Garn-St. Germain Depository Institutions Act prohibits calling a loan due when a borrower transfers property to a spouse who becomes a co-owner, as long as the property is a residential dwelling with fewer than five units.9Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions
The protection covers the due-on-sale clause only. It does not add your spouse to the loan itself.
Risks to Weigh Before You Record
You May Be Converting Separate Property Into Community Property
If you owned the home before marriage or received it by gift or inheritance, it is likely your separate property under California law. Adding your spouse to the deed transmutes it into community property or joint tenancy, depending on the deed’s language. California Family Code Section 852 governs transmutations and requires a written declaration accepted by the spouse whose interest is being reduced.10California Legislative Information. California Family Code 852 The deed itself satisfies that writing requirement, so the transmutation is valid the moment you record it.
If the marriage later ends in divorce, property that was once entirely yours is now subject to division, and in California your spouse would generally be entitled to half. A recorded transmutation is hard to undo. If the home is your separate property and a meaningful piece of your wealth, talk with a family law attorney before recording anything.
Your Spouse’s Creditors May Reach the Home
Once your spouse is on title, the property may become reachable by their creditors. In California’s community property system, a judgment creditor of one spouse can often lien community real property even when the other spouse had nothing to do with the debt. If your spouse has existing debts, outstanding judgments, or a rocky financial history, adding them to title puts the house in reach. The homestead exemption offers some protection against forced sale, but it does not stop a lien from attaching.
Title Insurance May Not Automatically Cover Your Spouse
Your existing owner’s title insurance policy was issued based on the ownership structure when you bought the home. Adding a spouse changes that structure. The policy typically continues to protect the original owner, but coverage for the newly added spouse is not always automatic. Call your title insurer after recording to ask whether an endorsement is needed to extend coverage. An endorsement costs far less than discovering a coverage gap years later.
