California Family Code § 1101: Breach of Fiduciary Duty Between Spouses

Plain-Language Summary

California Family Code § 1101 allows one spouse to sue the other for violating fiduciary duties involving community property. These duties include full disclosure, honesty, and fair dealing. If a spouse hides, misuses, or improperly transfers community property without consent, the other can seek legal remedies — including monetary awards, reallocation of assets, or full ownership of the wrongfully handled property. Section 1101 applies during marriage, separation, and even after a spouse’s death. The law protects each spouse’s equal interest in marital property and ensures that neither takes unfair advantage of the other.

Real-World Examples

Hidden assets: A spouse wins a lottery but does not disclose it during divorce. The court can award 100% of the hidden asset to the innocent spouse, as a penalty for breach of fiduciary duty.
Unauthorized transfers: One spouse deeds a jointly owned house to a third party without consent. The harmed spouse may bring a § 1101 claim to unwind the transaction and recover their interest.
Wasting community assets: A spouse spends large amounts of community funds on gambling or an extramarital affair. The court can reimburse the other spouse for their share of the loss.
Nondisclosure in divorce: A spouse fails to list a business account in the divorce disclosures. The court may reopen the case and award a monetary remedy under § 1101(g) or (h).
Claims after death: Even if a spouse dies, the surviving spouse may bring a § 1101 claim against the decedent’s estate for breaches that impaired their share of the community property.
