Marry in one of the nine community property states and the law quietly rewrites who owns the house: not the spouse on the deed, not the spouse who earned the money — both of you, half and half, for almost everything acquired during the marriage. This page is how the rule works, what stays separate, and the moments it matters most — a death, a divorce filing, and the day the home is sold.
Community property starts from a presumption: property either spouse acquires during the marriage belongs to the community — both spouses, equally — unless it falls in a separate-property exception. Earnings are community funds the moment they are paid, whoever earned them, so a home bought with either spouse's paycheck is community property even if the deed names one spouse alone and even if the other spouse never signed anything at the purchase. The presumption is strong: the spouse claiming a home is separate generally carries the burden of proving it, with records. Nine states run this system for every married couple — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin — and a handful of others let couples opt in by a written agreement or trust. In the remaining common-law states the starting point is the opposite: ownership follows the title.
Three categories stay one spouse's own. Property owned before the marriage. Property received during the marriage by gift or inheritance to that spouse alone. And, in most community property states, the rents and profits produced by separate property — though not all: Texas, for one, generally treats income from separate property as community, which is why the details are always the property state's own statute. Separate property does not stay separate by intention alone. Mix it untraceably with community money — separate funds poured into a community account and spent from it for years — and it can be treated as community by commingling; sign a written agreement converting it and it is community by transmutation. The reverse also happens quietly: marital earnings paying down the mortgage on a premarital home can earn the community a reimbursable share of that home in many states, so a house that started separate does not always end entirely separate.
Because each spouse owns a real half, each half can be planned. A spouse's will can leave their half to anyone — children from an earlier marriage are the classic case — and if there is no will, most community property states pass the half to the surviving spouse by intestacy, a default that does not fit every family. Couples who want the survivor to take the whole home automatically can usually say so on the deed itself: community property with right of survivorship, offered in several community property states, moves the whole home to the survivor outside probate. In a divorce, the community property is divided under the state's own rule — an equal division in some states, a just-and-right or equitable division in others — while separate property stays with its owner, which is why the characterization fight (community or separate?) is usually the whole case. Premarital and postmarital agreements can rewrite most of this in advance, in writing, with the formalities the state requires.
Equal ownership means equal say at the closing table: in community property states, both spouses generally must sign to sell community real estate or to borrow against it, even when only one name is on the deed — a title company will ask for the non-titled spouse's signature precisely because the community owns the home. The tax side carries the system's best-known feature: when the first spouse dies, generally both halves of community property receive a stepped-up basis to the home's value at that date — the survivor's half steps up too, not just the half that passed through the estate. In a common-law state, by contrast, only the deceased spouse's share of a jointly held home steps up. Stated generally and never as tax advice: for a long-held, much-appreciated home, that difference can be the largest single financial fact about how a married couple holds title.
Homeowner HQ keeps the homeowner's side of the record straight whichever system your state runs on: your own agent's monthly updates track your home's value and equity — the number each spouse's half is a half of, and the number the basis step-up is measured from at a first death. The guides in this series cover the ownership family side by side: joint tenancy and its survivorship, tenancy in common and its separate shares, the life estate, and the transfer-on-death deed, so a couple can compare the form on their deed with the forms they might choose at the next purchase or refinance, when the vesting line is written again.
Homeowners are always free. Realtors pay $25/mo all-in and lenders pay $25/mo to join, at any book size, with no setup fee; messaging is included free for realtors, and lender messaging is $100/mo ($125/mo total for lenders). A lender-sponsored realtor joins for $0.
Community property is a system of marital ownership used in nine states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin — in which marriage itself is treated as an economic partnership. The core rule: property acquired by either spouse during the marriage is owned equally by both, half and half, regardless of whose name is on the title and regardless of which spouse earned the money used to buy it. A home bought during the marriage with either spouse's earnings is the textbook example — it belongs to both spouses even if the deed names only one. Debts acquired during the marriage are likewise generally community obligations. A handful of other states let a married couple opt into community property treatment by a written agreement or trust. Everywhere else — the large majority of states — uses the common-law system instead, where ownership of a home follows the title. The system that governs a home is the law of the state where the home sits, not the state where the couple married, so a move can change the answer for the next purchase even when it changes nothing about the last one.
Generally yes, in a community property state, if it was bought during the marriage with marital earnings: the community presumption attaches to the acquisition, not to the names typed on the deed, and a spouse who is not on title still owns an undivided half. Title wording still matters at the edges. A deed that takes title in a survivorship form — community property with right of survivorship, available in several community property states, or joint tenancy — mainly changes what happens at death, and in some states how a home titled one way can be recharacterized; a written agreement between the spouses can also change separate property into community property or the reverse, under formalities that vary by state. The exceptions that keep a home separate are about the money and the timing, not the paperwork: bought before the marriage, or bought during it entirely with one spouse's separate funds — a gift or inheritance kept separate and traceable — and even then, marital money spent on mortgage principal or improvements can earn the community a reimbursable share under many states' rules. Couples are surprised in both directions: a spouse left off the deed who owns half anyway, and a spouse on the deed of a premarital home who owns none of it. The deed, the dates and the source of the money decide; an attorney in the property's state reads those three.
Each spouse owns a full half, and each half is theirs to plan with. A spouse can leave their half of community property to anyone in their will — adult children, for example — and it passes through their estate like other property. If there is no will, most community property states send the deceased spouse's half to the surviving spouse under intestacy, but that is a default, not a guarantee, and blended families are where it surprises people. The form on the deed can override all of this: where the couple holds as community property with right of survivorship — a title option in several community property states — the survivor takes the whole home automatically, outside probate, whatever the will says. One quiet advantage arrives with either route: at the first spouse's death, generally both halves of community property — not just the deceased spouse's half — receive a stepped-up tax basis to the home's value at that date, which can erase decades of taxable gain when the survivor later sells. That full step-up is specific to community property, and it is one reason couples moving from a common-law state sometimes choose to hold a new home in a community form where their state allows it.
