Yes, a married person can buy a house alone in California, but putting only your name on the deed does not make the home yours alone. California’s community property law presumes that anything either spouse acquires during the marriage belongs to both of you equally, regardless of whose name is on the title or whose paycheck funded the purchase. To actually own the home as your separate property, you have to fund it with separate money, title it in your separate capacity, and get your spouse to sign a written document giving up their community interest. Skip any one of those steps and the home can end up half your spouse’s in a divorce or estate settlement.
Why Your Name Alone on the Deed Isn’t Enough
California Family Code Section 760 says all property acquired by either spouse during the marriage is community property. The statute does not care whose name is on the deed or who earned the money.1California Legislative Information. California Code Family Code 760 – Community Property The presumption attaches automatically the moment you close escrow. Rebutting it takes affirmative steps by both spouses, not just a title choice at the escrow office.
This is the trap most buyers walk into. They assume a solo signature on the grant deed settles the question. It does not.
What Counts as Separate Property
Family Code Section 770 defines separate property in three categories:2California Legislative Information. California Code FAM 770 – Separate Property
- Anything you owned before you married, including money in pre-marriage bank accounts.
- Gifts and inheritances received during the marriage that were directed to you specifically, not to both spouses.
- Rents, dividends, and profits generated by assets in either of the first two categories.
Here is the catch for homebuyers: wages you earn during marriage are community property, even if they land in an account that only has your name on it. To buy the house as your separate property, every dollar that goes into the purchase has to trace back to one of those three sources. If an inheritance sat in a joint checking account for two years, mixed with paycheck deposits, a court may treat those funds as hopelessly commingled. The spouse claiming separate ownership carries the burden of proving the tracing, and documentation (bank statements, wire records, closing statements from a prior sale) is what wins or loses that argument.
The Three Steps to Buy a House as Separate Property
Fund the Purchase With Separate Money
The down payment, closing costs, and any out-of-pocket expenses at the purchase need to come entirely from traceable separate-property funds. An inheritance held in your own account. Proceeds from the sale of something you owned before the marriage. Investment returns on pre-marital assets. If you use any community funds, you have created a community claim right at the start.
Title the Property in Your Separate Capacity
The grant deed should expressly identify you as taking title alone, with vesting language such as “Jane Smith, a married woman, as her sole and separate property.”3Sacramento County Public Law Library. Interspousal Transfer Deed That phrasing signals your intent to future lenders, buyers, and courts. On its own, though, it does not defeat the community property presumption.
Have Your Spouse Sign an Interspousal Transfer Deed
Family Code Section 852 requires that changing the character of property between spouses (a “transmutation”) be in writing, with an express declaration signed, consented to, or accepted by the spouse whose interest is being affected.4California Legislative Information. California Family Code 852 – Transmutation A verbal understanding will not work. The standard tool is an interspousal transfer deed, in which the non-purchasing spouse conveys any community interest in the home to the purchasing spouse as their sole and separate property.
Lenders and title companies will usually insist on this step anyway, because California requires both spouses to join in any encumbrance of community real property.5California Legislative Information. California Code FAM 1102 – Management and Control of Community Real Property The deed should be recorded with the county to protect against later third-party claims.
A quitclaim deed can technically accomplish the same transfer, but the interspousal transfer deed is generally preferred in California. Spousal transfers are excluded from property tax reassessment, and the interspousal form makes that exclusion clear on its face, which avoids unnecessary questions from the county assessor.
Your spouse is giving up a real right by signing: their presumptive 50% community interest in the home. Both spouses should go into this with their eyes open, and ideally with independent legal advice.
Qualifying for the Mortgage on One Income
The legal mechanics are one hurdle. Getting the loan is another. When only one spouse applies, the lender evaluates that spouse’s income, credit, and debt-to-income ratio in isolation. Buying power can drop sharply compared to a two-income application.
FHA-insured loans add a complication specific to community property states. Under FHA guidelines, the lender has to pull the non-borrowing spouse’s credit and count that spouse’s debts in the borrower’s qualifying ratio, even though the spouse is not on the loan. Significant student loans, a car payment, or credit card balances on the non-borrowing spouse’s side can sink an FHA application.
Conventional loans backed by Fannie Mae or Freddie Mac do not impose that requirement. The lender generally looks only at the applying spouse’s debts and income. If the non-borrowing spouse carries heavy liabilities, conventional financing is often the more realistic path.
Keeping It Separate After You Close
Buying the home correctly is only the start. How you pay for it from here on determines whether it stays separate property or slowly turns into a shared asset. This is where most married solo buyers slip up without knowing it.
The Commingling Problem
Commingling happens when community money gets mixed into your separate asset. The classic example: you buy the home with an inheritance, then start paying the mortgage out of a joint account funded by both spouses’ paychecks. Those community-funded principal payments create a community interest in a home that started as yours alone.
Not every expense creates a claim. Paying property taxes, homeowner’s insurance, and routine maintenance from community funds does not generate a reimbursable community interest. Payments that reduce the mortgage principal, fund the down payment, or pay for significant improvements do.6California Legislative Information. California Code FAM 2640 – Reimbursement of Contributions
The Moore/Marsden Calculation
When community funds pay down the mortgage on a separate-property home, California courts use a formula known as the Moore/Marsden analysis (named for two appellate cases) to figure out what share of the equity the community has earned. The community’s share is based on how much principal community funds paid off, measured against the purchase price, and that percentage is then applied to the home’s fair market value at divorce.
The practical result: the longer community funds pay the mortgage, and the more the property appreciates, the larger the community’s slice becomes. Appreciation gets shared on the community’s percentage, not just the dollars paid in.
How to Prevent It
Keep a dedicated separate-property bank account and pay all housing costs from it. Fund that account only with separate-property income, such as rent from a pre-marital rental or returns on pre-marital investments. Document every deposit and every payment. If you ever have to tap community funds for the house, treat it as the creation of a potential claim and keep records of the amount and purpose.
Reimbursement Rights Under Section 2640
Family Code Section 2640 gives a spouse the right to be reimbursed for separate-property contributions made to community property or to the other spouse’s separate property in a divorce. Reimbursable contributions include down payments, principal payments, and improvements. Interest, insurance, maintenance, and property tax payments are not reimbursable.6California Legislative Information. California Code FAM 2640 – Reimbursement of Contributions
Reimbursement is dollar for dollar, with no interest and no inflation adjustment. It also cannot exceed the net value of the property at division, so if you put $200,000 of separate funds into a house that is worth only $150,000 net at divorce, you recover $150,000.
Either spouse can waive reimbursement rights, but only in writing and only through an explicit waiver. A waiver might appear in a prenuptial agreement, a postnuptial agreement, or the transmutation document itself. Courts will not infer a waiver from silence or vague property-division language.
Capital Gains When You Sell
Sole ownership does not shrink the capital gains exclusion on your eventual sale. A married couple filing jointly can exclude up to $500,000 of gain on the sale of a primary residence, and under IRS rules only one spouse has to meet the ownership test. Both spouses have to meet the use test, meaning both lived in the home as their main residence for at least two of the five years before the sale.7Internal Revenue Service. Topic No. 701, Sale of Your Home Filing separately drops the exclusion to $250,000 per spouse.
When Buying Alone Actually Makes Sense
Not every married buyer has a reason to go through all this. Sole ownership tends to pay off in a few specific situations: when one spouse brings significant pre-marital wealth or an inheritance they want to preserve, when one spouse has credit problems that would hurt mortgage qualification, when a prenuptial agreement contemplates keeping certain assets separate, or when one spouse owns a business and wants to shield the home from potential business creditors tied to the other spouse.
For couples who just want things straightforward, joint ownership (including community property with right of survivorship) is usually simpler and brings its own tax advantages, including a full stepped-up basis when one spouse dies. The decision to buy alone should answer a real financial or legal objective, not just a preference for a single name on the paperwork.
