Date of Separation in California: The Date That Decides What You Keep

Your date of separation is the line that divides shared property from separate property. Income earned and debts taken on before it are generally community property, split between you. After it, they are generally yours alone.

That makes it one of the most consequential dates in a California divorce, and one of the most frequently disputed — because a difference of a few months can move a bonus, a stock vesting, or a credit card balance from one side of the line to the other.

What the law requires

Family Code section 70 defines the date of separation as the date of a complete and final break in the marital relationship, shown by both of the following:

• One spouse expressed to the other the intent to end the marriage; and
• That spouse's conduct was consistent with that intent.

Both limbs are required. Privately deciding the marriage is over does not start the clock. Neither does behaving distantly without ever saying so.

The 2016 change that matters most

You no longer need separate addresses.

Before 2016, courts read the old "living separate and apart" language as requiring separate residences — a reading confirmed in In re Marriage of Davis (2015). Senate Bill 1255, signed in July 2016, was enacted specifically to abrogate that decision and added section 70.

The result: spouses can be legally separated while still living under one roof. That matters enormously in California, where a couple may stay in the same house for months because neither can afford to move out.

Living together does make the date harder to prove — but it no longer makes separation impossible.

What evidence establishes the date

The court considers all relevant evidence. In practice these carry weight:

• A message, email or letter where one spouse states the marriage is over — the clearest evidence there is
• Separating finances: new individual accounts, splitting bills, stopping joint spending
• Moving to a different bedroom, or ceasing to function as a couple socially
• Telling family or friends, who can later confirm timing
• Consulting a lawyer, or filing the petition
• Ceasing to attend events together as a couple

Conduct pulling the other way — holidays taken together, continued joint purchases, attempts at reconciliation — is exactly what the other side will point to.

Why the date is worth arguing about

Concrete examples of what turns on it:

• Earnings. A salary earned after separation is separate property.
• Bonuses and equity. Whether a bonus or a vesting tranche falls before or after can be worth a great deal.
• Debt. Debt run up after separation is generally the spender's own.
• Business growth. Increases in value after separation may be separate.
• Length of marriage. The date closes the marriage period, which feeds the support analysis — including the ten-year threshold that affects how long support may be ordered.

How to establish the date deliberately

If your marriage has ended and you expect the date to be contested, you can create the evidence rather than hope it exists.

• Say it clearly, in writing. A dated message or email stating that the marriage is over satisfies the first limb of section 70 and is difficult to argue with later.
• Make the conduct match. Separate accounts, split the bills, stop joint purchases. The second limb is about behaviour.
• Keep a short record. When you moved rooms, when you opened your own account, when you told family.
• Be consistent. Continuing to present as a couple undercuts the date you are claiming.

None of this requires moving out, and none of it requires filing. It requires the intent to be communicated and the conduct to follow.

Attempts at reconciliation

A genuine reconciliation can reset the date — the "complete and final break" was not final after all.

A brief attempt that fails may not. Courts look at whether the couple genuinely resumed the marital relationship or simply had a short period of contact. There is no bright line, which is why the surrounding conduct matters so much.

Frequently asked questions

Can we be separated while living in the same house in California?

Yes. Family Code section 70 was added in 2016 specifically to overturn the requirement of separate residences. You need an expressed intent to end the marriage and conduct consistent with it — not a different address.

Who decides the date of separation if we disagree?

The court, considering all relevant evidence. Where spouses put forward different dates, it becomes a contested factual issue, and documentary evidence from the time carries far more weight than later recollection.

Is the date of separation the date we filed for divorce?

Not necessarily. Filing is strong evidence, but separation often occurred earlier. The filing date sets a ceiling, not the date itself.

What happens to income earned after separation?

Earnings after the date of separation are generally the separate property of the spouse who earned them, as are debts they incur — which is precisely why the date is contested when it falls near a bonus or a large purchase.

Fix the date early

The evidence that settles this is created at the time, not reconstructed afterwards. If your marriage has ended, a dated written record of that conversation is worth more than anything you can assemble later.
