US-CaliforniaIs my spouse's retirement account community property?
Yes, in California, retirement accounts earned during marriage are generally community property, even if held in only one spouse’s name.
What the Law Says
California law presumes that all property acquired by either spouse during marriage is community property — including contributions to and appreciation of retirement accounts.
This rule applies regardless of whose name is on the account. For example, a 401(k), IRA, pension, or CalPERS account funded with wages earned during marriage belongs equally to both spouses — 50% each — unless a valid prenuptial or postnuptial agreement says otherwise.
However, retirement funds contributed before marriage, or after separation, are separate property. If an account contains both pre-marital (separate) and marital (community) funds — a 'mixed' account — the court may use tracing methods (like the 'van Camp' or 'Pereira' approaches) to determine what portion belongs to each estate.
Importantly, the characterization of the account depends on when the funds were earned, not when they were deposited or vested.
Statutory TextAll property, real or personal, wherever situated, acquired by a married person during the marriage while domiciled in this state is community property.
— Family Code § 760 — Definition of community property
Statutory TextThe separate property of a married person includes all property owned by the person before marriage.
— Family Code § 770(a)(1) — Separate property definition
What Courts Have Said
California courts have consistently upheld the community property treatment of retirement benefits earned during marriage, emphasizing timing of earnings over account title or control.
Held that non-vested pension rights earned during marriage are community property subject to division — rejecting the idea that only vested benefits count.
Confirmed that retirement benefits are community property to the extent earned during marriage, and that separate property contributions must be traced with clear evidence.
What to Do
Gather account statements covering the entire marriage (and pre-marriage, if applicable).
Identify the date of marriage and date of separation — these define the community period.
Work with a forensic accountant or attorney to trace separate vs. community portions if the account predates marriage or includes rollovers.
Obtain a Qualified Domestic Relations Order (QDRO) for employer-sponsored plans (e.g., 401(k), pensions) to legally divide funds without tax penalties.
File the QDRO with the plan administrator *after* the divorce judgment is entered — it’s not automatic.
