General Principles, the Community Estate, and Marital Economic Community

California is one of nine community property states, and its system rests on a single organizing idea: a marriage is an economic partnership in which the labor of each spouse during the marriage belongs equally to both. The master rule is Family Code §760, which provides that 'all property, real or personal, wherever situated, acquired by a married person during the marriage while domiciled in this state is community property.' Three elements of that sentence do all the analytical work, and you should isolate each one on every essay.

First, 'acquired during the marriage' — the asset must come into existence, or the right to it must vest, between the date of marriage and the date of separation. Second, 'by a married person' — the system attaches to legal marital (or registered-domestic-partner) status, not to mere cohabitation. Third, 'while domiciled in this state' — California's community presumption reaches property acquired while the couple is domiciled here, while property accumulated during marriage in a non-community-property jurisdiction is handled separately under the quasi-community-property rules (FC §125), covered in the distribution section.

The mirror-image rule is Family Code §770, which defines separate property: property owned before marriage, property acquired during marriage by gift, bequest, devise, or descent (inheritance), and the rents, issues, and profits of separate property. Read §760 and §770 together and you have the entire characterization engine: community is the labor of the marriage and what labor buys; separate is what you brought in, what someone gave you, and what your separate capital earns passively.

The single most heavily tested temporal concept is the duration of the 'marital economic community' — the window during which the spouses' earnings are community. It opens on the date of marriage and closes on the date of separation. The date of separation is now defined by Family Code §70 (added in 2017 to override In re Marriage of Davis (2015), which had suggested living in separate residences was required).

Under §70, separation occurs on the date that a complete and final break in the marital relationship has occurred, as evidenced by BOTH (a) one spouse expressing to the other the intent to end the marriage, AND (b) conduct consistent with that intent. Crucially, the statute states the court must consider all relevant evidence and that spouses may be 'separated' even while still living in the same residence — and conversely may NOT be separated merely because one is temporarily away (e.g., military deployment, hospitalization).

The consequence is dramatic: Family Code §771 provides that the earnings and accumulations of a spouse, and of any minor children in that spouse's custody, while living separate and apart from the other spouse, are the separate property of that spouse. So a year-end bonus earned by labor performed after separation is separate, even if the marriage is not yet dissolved. On the exam, the date of separation often determines the characterization of a key asset (a bonus, a stock vest, a lottery ticket), so pin it down with §70's two-part test before you characterize anything earned near the end of the relationship.

California is sometimes described as a 'community-in-profits' or 'item' system, and the ownership theory matters. Under Family Code §751, the respective interests of each spouse in community property during continuance of the marriage are present, existing, and equal interests. This is not a mere expectancy that ripens at divorce — each spouse owns an undivided one-half interest in EVERY community asset right now. That theory has practical bite.

It is why a spouse's one-half community interest can pass by will at death (you can devise your half of the community estate), why creditors of one spouse can reach community property, and why the management-and-control rules (covered later) impose fiduciary duties on the managing spouse rather than giving that spouse ownership. At dissolution, the present-interest theory is enforced by Family Code §2550, which requires the court — absent a written agreement or oral stipulation in open court — to divide the community estate of the parties EQUALLY.

California is a strict equal-division (not equitable-division) state: the court divides the aggregate net value 50/50, though it has discretion as to which specific assets go to which spouse (and may order a cash equalizing payment). Contrast this with 'equitable distribution' states, where a judge weighs fairness factors; in California, the percentage is fixed by statute, and an unequal division on dissolution generally requires a recognized statutory exception (e.g., deliberate misappropriation, certain debt-allocation rules, educational-loan assignment under §2641, or community-property tort liabilities).

Several protective doctrines extend or imitate community treatment where the formal predicate (a valid marriage during the relevant window) is imperfect. The PUTATIVE SPOUSE doctrine, codified at Family Code §2251, applies when a marriage is void or voidable but at least one party had a good-faith, objectively reasonable belief that the marriage was valid (e.g., a prior divorce that turned out to be invalid). The court divides the 'quasi-marital property' — property that would have been community or quasi-community had the union been valid — as if it were community property, protecting the innocent, good-faith spouse.

A good-faith belief that becomes unreasonable cuts off putative status going forward. REGISTERED DOMESTIC PARTNERS are, by statute, treated identically to spouses for all community property purposes — every rule in this outline applies to them. By contrast, unmarried cohabitants with no registration get NO community property rights; their remedy, if any, lies in MARVIN v. Marvin (1976) contract/equitable theories (express or implied agreements to pool earnings), which sound in contract and quantum meruit, not in the Family Code.

Finally, note the COMMON-LAW MARRIAGE point: California does not recognize common-law marriages contracted within the state, but under the place-of-celebration rule it WILL recognize a common-law marriage validly formed in a state that permits them — and that recognized couple then gets full California community property treatment.
