Management, Control, and Spousal Fiduciary Duties

California abandoned the old 'husband as manager' regime decades ago. Today, Family Code §1100(a) gives EACH spouse EQUAL management and control of the community PERSONAL property, and Family Code §1102 gives each spouse equal management and control of community REAL property. 'Equal management and control' means that, as a default, EITHER spouse acting ALONE may buy, sell, spend, invest, or encumber community property as fully as if it were that spouse's own separate property — without the other's signature.

This is efficient (the couple need not co-sign every grocery purchase or stock trade) but it creates risk that one spouse will dissipate or misdirect community assets, which is why the Family Code layers several CONSENT exceptions on top of the equal-management default and backs them with fiduciary duties. When you see a management problem, your job is to determine whether the transaction falls within the broad equal-management default (either spouse may act alone) or within one of the specific exceptions that require the OTHER spouse's joinder or written consent.

The most important exceptions concern (1) real property, (2) gifts and below-value transfers, and (3) a community-property business.

REAL PROPERTY is the most protected category. Under Family Code §1102, BOTH spouses must JOIN in executing any instrument by which community real property is SOLD, CONVEYED, or ENCUMBERED (and a lease of more than one year). A unilateral transfer of community real property by one spouse alone is therefore defective.

The remedies are nuanced: where one spouse alone executes an instrument encumbering or conveying the property, the non-consenting spouse may bring an action to VOID the transaction — and §1102 contains a one-year limitations rule protecting certain bona fide purchasers/encumbrancers for value where the instrument was made by a spouse holding record title (the non-consenting spouse must act within ONE YEAR to void an encumbrance executed by the titled spouse). For an unauthorized GIFT of community real property, the non-consenting spouse may set it aside.

The practical exam point: a spouse cannot unilaterally mortgage or sell the family home (community real property) without the other's joinder, and a deed signed by only one spouse is vulnerable to being set aside. Distinguish community real property held in BOTH names (clearly requires joinder) from community property the acting spouse holds in his name alone of record — the latter implicates the §1102 record-title and one-year-to-void protections for third parties.

GIFTS and BELOW-VALUE transfers are sharply restricted regardless of whether the asset is real or personal. Family Code §1100(b) provides that a spouse may NOT make a GIFT of community personal property, or dispose of community personal property for LESS than FAIR AND REASONABLE VALUE, without the WRITTEN CONSENT of the other spouse. The same protective logic restricts gifts of community real property. When a spouse violates this rule — say, the husband gives a community-funded car to his girlfriend, or sells community stock to a relative for a token sum — the non-consenting spouse has powerful remedies.

DURING the marriage, the wronged spouse may void the ENTIRE gift and recover the whole asset (because the gift impaired her present one-half interest and the law does not force her to accept a partial recovery while the marriage continues). After the donor spouse's DEATH or at dissolution, the wronged spouse may recover the donor's ONE-HALF interest (she keeps her own half and reclaims the half the donor improperly gave away).

A community-property BUSINESS gets a special management rule under Family Code §1100(d): the spouse who OPERATES or manages a community-property business has the PRIMARY management and control of that business and may act alone in the ordinary course — but must give PRIOR WRITTEN NOTICE to the other spouse before SELLING, LEASING, EXCHANGING, ENCUMBERING, or otherwise disposing of ALL or SUBSTANTIALLY ALL of the business's personal property. Failure to give notice does not void an act protected by third-party reliance, but it is a breach exposing the managing spouse to liability for any resulting impairment of the other's interest.

Overarching all of this is the FIDUCIARY duty. Family Code §721 provides that spouses are subject to the general rules governing FIDUCIARY relationships that control the actions of persons having relationships of personal confidence — specifically the duties of a nonmarital business partner under the Corporations Code — and that, in transactions between themselves, neither may take unfair advantage of the other.

Family Code §1100(e) makes this concrete in the management context: each spouse must act in GOOD FAITH with respect to the other in managing community property, and the duties include the same rights and duties of nonmarital business partners, including the obligation of FULL DISCLOSURE of all material facts regarding the existence, characterization, and valuation of community assets and debts, and access to information and records on request (an ACCOUNTING duty).

Remedies for breach are set out in Family Code §1101: the wronged spouse may claim a share of community assets transferred or impaired in breach, and the court may award the wronged spouse FIFTY PERCENT (or an amount equal to fifty percent) of the value of any asset that should have been disclosed or that was transferred in breach — or, where the breach involves MALICE, FRAUD, or OPPRESSION, ONE HUNDRED PERCENT of the asset's value (§1101(h)).

Independently, at dissolution Family Code §2602 lets the court award to one spouse, as that spouse's share, the amount the OTHER spouse DELIBERATELY MISAPPROPRIATED from the community — and §2556 lets a court divide omitted or unadjudicated assets even after judgment. The headline exam rule: a spouse who hides a community asset (e.g., undisclosed lottery winnings, as in In re Marriage of Rossi) can lose the ENTIRE asset to the wronged spouse under §1101(h)/§2602.
