Yes, a married person can buy a house alone in California, but putting only your name on the deed is not enough to make the home yours alone. California is a community property state, and the law presumes that anything either spouse acquires during the marriage belongs equally to both. To buy a house as your separate property, you have to fund the purchase with separate money, title it correctly, and have your spouse sign a written document giving up any community interest. Miss any of those steps and the home you thought was yours can end up half your spouse’s in a divorce.
Why Your Name on the Deed Is Not Enough
California Family Code Section 760 says that all property acquired by either spouse during the marriage is community property, regardless of whose name is on the title or whose earnings paid for it.1California Legislative Information. California Code Family Code 760 – Community Property The presumption attaches automatically the moment you close. Overcoming it is the actual work of buying a house alone in California, and it takes affirmative steps from both spouses before or at closing.
What Counts as Separate Money
Family Code Section 770 defines separate property in three categories: anything you owned before the marriage, anything you received during the marriage as a gift or inheritance directed to you individually, and any income or profits generated by those assets.2California Legislative Information. California Code FAM 770 – Separate Property
Your paycheck is not on that list. Wages earned during marriage are community property even if they land in an account with only your name on it. To buy a home as separate property, every dollar you put toward it has to trace back to one of the three separate categories above. That is where deals get complicated, because most people’s money is more mixed than they realize.
The Three Steps to Buy a Home as Your Separate Property
Fund the Purchase Entirely With Separate Funds
Down payment, closing costs, and any initial expenses need to come from money you can trace to a separate-property source: an inheritance, proceeds from selling something you owned before marriage, or returns on pre-marital investments. Documentation matters more than the current account balance. If an inheritance sat in a joint checking account for two years before the purchase, a court may view those funds as commingled with community money and treat the home as community property.
The tracing burden falls on the spouse claiming separate ownership. Bank statements, wire transfer records, account histories, and closing documents from any prior sale of separate property all serve as evidence. The cleaner the paper trail, the stronger the claim.
Take Title in Your Sole and Separate Capacity
The grant deed needs to expressly identify you as taking title in your separate capacity. Standard vesting language reads something like “Jane Smith, a married woman, as her sole and separate property.” That language signals to future buyers, lenders, and courts that the property was never intended to be community property.3Sacramento County Public Law Library. Interspousal Transfer Deed
Deed language alone does not do the job, though. Because of the community property presumption, California requires something more.
Get a Written Transmutation From Your Spouse
Under Family Code Section 852, changing the character of property between spouses (called a “transmutation”) is only valid if it is made in writing, with an express declaration that the spouse giving up their interest has signed, consented to, or accepted.4California Legislative Information. California Family Code 852 – Transmutation
Your spouse needs to sign a written document that explicitly states the property will be your sole and separate property. A vague understanding or verbal agreement is not enough. The written declaration must be clear about what interest is being given up, and it should be recorded with the county to protect against later claims from third parties. This requirement exists because courts saw too many informal spousal promises about property turn into litigation.
The Interspousal Transfer Deed
The standard way to satisfy Section 852 in a purchase is an interspousal transfer deed. Your spouse signs this specialized grant deed to transfer any community property interest in the home to you. California law requires both spouses to join in any sale or encumbrance of community real property, so lenders and title companies will insist on this step before closing anyway.5California Legislative Information. California Code FAM 1102 – Management and Control of Community Real Property
A properly drafted interspousal transfer deed states that it is “the express intent of the grantor, being the spouse of the grantee, to convey all right, title and interest of the grantor, community or otherwise, in and to the herein described property to the grantee as his/her sole and separate property.”3Sacramento County Public Law Library. Interspousal Transfer Deed That specific, unambiguous language is what Section 852 demands.
Interspousal transfer deeds are generally preferred over quitclaim deeds in California because transfers between spouses are excluded from property tax reassessment, and the interspousal form makes that exclusion clear on its face.
What Your Spouse Is Actually Giving Up
Signing the deed is not a formality. Your spouse is surrendering a real legal right: a presumptive 50% community property interest in the home. If the marriage later ends in divorce, that spouse generally cannot claim a share of the property’s equity, assuming the separate property status was properly maintained. Both spouses should make this decision with open eyes, and ideally each with independent legal advice.
Qualifying for a Mortgage on One Income
The legal steps are often less of a barrier than the loan. When only one spouse applies, the lender looks at that spouse’s income, credit, and debt-to-income ratio in isolation. A household that qualifies easily on two incomes can find the buying power drops considerably when one spouse applies alone.
FHA loans add a wrinkle specific to community property states. Under FHA guidelines, the lender must pull the non-borrowing spouse’s credit report and include that spouse’s debts in the borrower’s qualifying debt-to-income ratio, even though the non-borrowing spouse is not on the loan. Significant student loans, car payments, or credit card balances held by your spouse can sink your application.
Conventional loans backed by Fannie Mae or Freddie Mac do not impose that requirement. If only one spouse applies for a conventional mortgage, the lender generally evaluates only that borrower’s debts and income. For married California buyers whose spouse carries meaningful debt, that difference alone can make a conventional loan the better path.
Keeping the Home Separate After Closing
Buying correctly is half the job. How you pay for the home going forward decides whether it stays separate property or gradually becomes part of the marital community. Most mistakes happen here, often unnoticed for years.
The Commingling Trap
Commingling happens when separate and community funds get mixed in ways that are hard to untangle. The classic scenario: you buy the home with an inheritance, then pay the monthly mortgage from a joint account funded by both spouses’ paychecks. Those community-funded payments create a community interest in what started as your separate asset.
Paying property taxes, homeowner’s insurance, and routine maintenance from community funds does not create a reimbursable community interest. But any payment that reduces the mortgage principal, funded the down payment, or paid for significant improvements does count as a community contribution.6California Legislative Information. California Code FAM 2640 – Reimbursement of Contributions
Moore/Marsden and Why Long Marriages Are Riskier
When community funds pay down the mortgage on a spouse’s separate-property home, California courts apply a calculation known as the Moore/Marsden analysis to determine what share of the equity the community earned. The community’s percentage is based on how much principal was reduced with community funds relative to the purchase price, and that percentage is then applied to the property’s fair market value at the time of divorce. The formula rewards appreciation. The longer community payments continue and the more the property appreciates, the larger the community’s share grows.
How to Prevent It
The simplest protection is a dedicated separate-property account. Fund it only with separate-property income (rent from a pre-marital rental, returns on pre-marital assets), and pay all housing costs from it. Document every deposit and every payment. If you ever need to use community funds for the home, understand that you are creating a potential reimbursement claim and keep records of how much was used and for what.
Reimbursement Under Family Code Section 2640
Section 2640 gives a spouse the right to be reimbursed for separate-property contributions to community property or to the other spouse’s separate property in a divorce. Reimbursable contributions include down payments, principal reduction payments, and payments for improvements. Interest, insurance, maintenance, and property taxes are excluded.6California Legislative Information. California Code FAM 2640 – Reimbursement of Contributions
Reimbursement is dollar-for-dollar with no interest and no inflation adjustment, and it cannot exceed the net value of the property at division. Contribute $200,000 of separate funds toward a home worth only $150,000 net at divorce and you get $150,000.
Either spouse can waive reimbursement rights in writing. The waiver might sit inside a prenuptial agreement, a postnuptial agreement, or the transmutation document itself. It has to be explicit; courts will not infer it from silence or general language.
When Buying Alone Actually Makes Sense
Not every married buyer has a reason to go through this. Sole ownership is most useful when one spouse brings significant pre-marital wealth or an inheritance and wants to preserve it, when one spouse’s credit would hurt mortgage qualification, when a prenuptial agreement contemplates keeping certain assets separate, or when one spouse’s business exposes the family to creditor risk.
For couples who simply want things clean, joint ownership as community property (or community property with right of survivorship) is usually simpler and carries its own advantages, including a full stepped-up basis for tax purposes when one spouse dies. The choice to buy alone should be driven by a real financial or legal objective, not by a preference for having one name on the paperwork.
