Splitting the House and the 401(k): Community Property, Date of Separation, and 'Watts Credits'
What you earned and saved during the marriage is usually split down the middle — but the date of separation, your separate property, and who's living in the house all change the math.

Ava: Michael, the big money question in most divorces: who gets the house and the retirement accounts? Is California really just a 50/50 split?
Michael Benavides, Esq.: For community property, essentially yes. Under Family Code section 760, almost everything acquired during the marriage — a house bought together, wages, and the growth in a 401(k) during the marriage — is community property, and it's divided equally. So if a retirement account grew by, say, two hundred thousand dollars during the marriage, that growth is generally split down the middle.
Ava: What about money someone brought into the marriage?
Michael Benavides, Esq.: That's separate property under Family Code section 770 — property owned before marriage, plus gifts and inheritances, stay yours. So if you walked in with sixty-seven thousand dollars in your own account and kept it separate, that's not on the table. The classic fight is characterization — sorting what's community from what's separate, especially when accounts got mixed.
Ava: You mentioned the date of separation matters. Why?
Michael Benavides, Esq.: Because it's the finish line for the community. Under Family Code section 70, the "date of separation" is when there's a complete, final break — one spouse intends to end the marriage and acts consistently with that. Earnings and acquisitions after that date are generally separate property. That's why couples fight over the exact date: it can move a chunk of a 401(k) or a bonus from "ours" to "mine." And if someone pulled money out of a retirement account during the marriage, that can still be a community asset to account for.
Ava: And the house — if one spouse stays living in it while the divorce drags on?
Michael Benavides, Esq.: Then you get into "Watts credits." Under In re Marriage of Watts, a spouse who has exclusive use of the community home after separation can be charged for the reasonable value of that use — effectively rent — which becomes a credit to the other spouse in the property division. So the answer to "should they be paying something to live there?" is often yes. Honest caveat: characterization, tracing separate property, valuing the home, and calculating Watts charges are all fact-intensive — two similar-looking marriages can divide very differently.
Ava: The through-line?
Michael Benavides, Esq.: Fifty-fifty is the starting rule for the community estate — but the date of separation, separate-property claims, and who's using the house are the levers that decide who actually walks away with what.
