What Is the Date of Separation in a California Divorce?

The Short Answer

In a California divorce, the date of separation is the date when a complete and final break in the marriage occurred, meaning one spouse told the other that the marriage was over and then acted in a way consistent with that decision. That is the definition in Family Code section 70. It is not the date you filed for divorce, not the date you moved into separate bedrooms, and not necessarily the date one spouse moved out. The date matters because everything either spouse earns or acquires after it is that spouse's separate property under Family Code section 771, while everything acquired before it during the marriage is presumed community property under Family Code section 760.

Couples fight over this date in courtrooms from the Riverside Family Law Courthouse to the Stanley Mosk Courthouse in Los Angeles because a difference of a few months can move a bonus, a business, a retirement contribution, or a debt from one column to the other, and can determine whether the marriage is treated as long-term for spousal support.

Why the Date of Separation Matters So Much

Three consequences follow from the date of separation. First, it ends the accumulation of community property. Under Family Code section 771, the earnings and accumulations of a spouse while living separate and apart from the other spouse are separate property. A commission earned in Irvine the month after separation belongs to the spouse who earned it. The same commission earned the month before separation is split equally under Family Code section 2550.

Second, it ends community responsibility for new debts. Debts incurred by either spouse after the date of separation are generally that spouse's separate obligation, and Family Code section 2622 assigns them accordingly. A spouse who runs up credit cards after the separation date will usually be assigned that debt alone. A spouse who claims an early separation date to escape a debt the other spouse incurred should expect the court to look closely at the evidence.

Third, it affects spousal support. Family Code section 4336 creates a presumption that a marriage of 10 years or more, measured from the date of marriage to the date of separation, is a marriage of long duration, which means the court retains jurisdiction over spousal support indefinitely rather than for a presumed period of about half the length of the marriage. A couple married nine years and eight months on one spouse's version of the separation date, and ten years and two months on the other's, has a real dispute. The length of the marriage is also a factor the court must weigh under Family Code section 4320 in setting the amount and duration of support.

How California Defines the Date of Separation: Family Code Section 70

For years, California courts applied a test drawn from cases such as In re Marriage of Hardin (1995) 38 Cal.App.4th 448 and In re Marriage of von der Nuell (1994) 23 Cal.App.4th 730, which asked whether the spouses had come to a parting of the ways with no present intention of resuming the marriage, judged by their conduct rather than by what one spouse privately believed. Then, in In re Marriage of Davis (2015) 61 Cal.4th 846, the California Supreme Court held that spouses could not be living separate and apart while still living under the same roof, which meant a physical move-out was effectively required.

The Legislature responded by enacting Family Code section 70, effective January 1, 2017, which overruled Davis. Section 70 defines the date of separation as the date that a complete and final break in the marital relationship has occurred, shown by two things. One spouse must have expressed to the other the intent to end the marriage, and that spouse's conduct must be consistent with that intent. The statute directs the court to consider all relevant evidence and expressly states that spouses can be separated while living in the same home. The test is objective. A spouse's undisclosed decision that the marriage is over does not start the clock. Telling the other spouse, in words or unmistakable conduct, that the marriage is over, and then behaving that way, does.

What Evidence Do Judges Look At to Decide the Date of Separation?

Judges apply section 70 to the facts of each marriage, and the cases that came before it still guide what counts as consistent conduct. In In re Marriage of Manfer (2006) 144 Cal.App.4th 925, the court held that the spouses' private understanding controlled over the public appearance they maintained for the sake of family and friends. In In re Marriage of Baragry (1977) 73 Cal.App.3d 444, by contrast, a husband who moved out but continued to eat dinner with the family, take his wife on trips, send her cards, and keep his mail at the family home was found not to have separated, because his conduct was inconsistent with a final break.

The facts that carry the most weight are direct communications about ending the marriage, such as a text or email saying the marriage is over, and the conduct that follows. Judges look at whether the spouses stopped sleeping together, whether they separated finances by opening individual accounts or stopping deposits into joint accounts, whether one spouse moved out or into a separate part of the house, whether they continued to attend family events as a couple, whether they went to marriage counseling, whether they took vacations together, whether they continued to file joint tax returns and how they described their status on those returns, whether either spouse dated other people, and what they told friends, family, and employers. No single fact decides the question. A spouse who says the marriage ended in March but went on a couples' trip to Palm Springs in June and celebrated an anniversary in August has a problem.

Does Moving Out Establish the Date of Separation?

Not by itself. Moving out is strong evidence, but section 70 asks whether there was a complete and final break, and a spouse who moves out for work, to cool off, or to give the other spouse space while attempting reconciliation has not necessarily separated. Conversely, spouses who cannot afford two households in Los Angeles or Orange County often remain in the same house long after the marriage has ended, and section 70 allows the court to find separation while they are still under one roof if the intent was communicated and the conduct was consistent.

Reconciliation attempts complicate the analysis. If the spouses separate, then genuinely reconcile and resume the marriage, the original separation date is generally erased and the community continues until the next final break. A brief attempt at counseling does not necessarily reset the date if the spouses never actually resumed a marital relationship, but a period of months living together as a couple usually does. Document what happened. If a reconciliation was attempted and failed, the communications about it will be the evidence the court relies on.

Where the Date of Separation Appears in Your Case

The date of separation is alleged in item 2 of FL-100, the Petition for Dissolution, and the responding spouse states his or her version in FL-120, the Response. If the two dates match, the issue is settled by agreement. If they differ, the court will have to decide it, either at trial or in a separate hearing. The date also drives the Preliminary Declaration of Disclosure. On FL-142, the Schedule of Assets and Debts, each spouse must list assets and debts and characterize them as community or separate, and the separation date determines that characterization for everything acquired near the end of the marriage. Family Code section 2104 and Family Code section 2105 require complete and accurate disclosures, and Family Code section 1101 gives the other spouse remedies for a breach of the fiduciary duty owed under Family Code section 721.

Parties can ask the court to decide the date of separation before the rest of the case by requesting bifurcation of that issue under Rule 5.390 of the California Rules of Court. Deciding the date first often makes settlement possible, because once each side knows which assets and income are in the community, the remaining division is largely arithmetic. In Riverside and San Bernardino County courts, this is frequently handled as a separate evidentiary hearing set on a Request for Order on FL-300, with each spouse filing declarations and exhibits on the separation facts.

How the Date of Separation Interacts With Valuation and Reimbursement

The date of separation is not the same as the valuation date. Under Family Code section 2552, community assets and debts are valued as near as practicable to the time of trial unless the court, for good cause, sets an alternative valuation date. That distinction matters for assets whose value depends on a spouse's post-separation efforts, such as a business or professional practice. Courts often value those assets at the date of separation, because the increase in value after that date is attributable to the operating spouse's separate labor, while passive assets such as a home in Corona or a brokerage account are valued at trial.

Separation also starts the clock on reimbursement claims. A spouse who pays community debts with separate earnings after separation may be entitled to reimbursement under the rule from In re Marriage of Epstein (1979) 24 Cal.3d 76, and a spouse who has exclusive use of a community asset such as the family home after separation may owe the community the reasonable value of that use under In re Marriage of Watts (1985) 171 Cal.App.3d 366. Both claims are measured from the date of separation, so a dispute over the date is also a dispute over the size of these credits.

Common Mistakes When Claiming a Date of Separation

The most common mistake is picking the date that produces the best financial result rather than the date the facts support. Judges notice when a spouse's chosen date conveniently falls just before a large bonus or just after the tenth anniversary, and inconsistent conduct will undercut it. The second mistake is silence. A spouse who has decided the marriage is over but never says so cannot rely on that private decision, because section 70 requires the intent to be expressed to the other spouse. If the marriage is over, say so clearly and in writing, and keep the message.

The third mistake is mixed signals after the claimed date. Continuing to share a bed, taking family vacations, posting anniversary messages on social media, continuing joint financial planning, and describing yourselves as married to third parties all suggest the break was not complete. The fourth is failing to preserve evidence. Texts, emails, bank records showing when accounts were separated, lease agreements, changes to insurance beneficiaries, and messages to friends and family are the proof, and they should be gathered early, before phones are replaced and accounts closed.

How to Prove Your Date of Separation

Build a chronology. List every event bearing on the end of the marriage with a date and the document that proves it. Identify the communication in which one spouse told the other the marriage was over, and then list what each spouse did afterward that was consistent with that decision. Collect the third-party evidence: what you each told family and friends, whether an employer or landlord was told, whether a new lease was signed, and whether accounts were separated. Where the other spouse's version depends on facts you can disprove, gather the records, such as a hotel receipt from a trip you took together after the date they claim.

If the issue will be tried, discovery is available. Requests for production, special interrogatories, and depositions can establish what the other spouse said to others about the marriage and when. Financial records subpoenaed from banks and employers show when money stopped flowing into joint accounts. A well-documented chronology filed with a declaration on FL-300 or FL-320, with exhibits, is far more persuasive than a declaration that simply asserts a date. Because the difference between two dates can be worth tens of thousands of dollars in property and years of spousal support, this is an issue worth preparing carefully.

Frequently Asked Questions

What is the legal definition of the date of separation in California?

Under Family Code section 70, the date of separation is the date a complete and final break in the marital relationship occurred, shown by one spouse expressing to the other the intent to end the marriage and by conduct consistent with that intent. Spouses can be separated while living in the same home.

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

No. The filing date is often months or years after the actual separation. The date of separation is alleged in FL-100 and FL-120 based on when the marriage actually ended, and the court decides it from the evidence if the spouses disagree.

Can we be separated if we still live in the same house?

Yes. Family Code section 70 overruled In re Marriage of Davis (2015) 61 Cal.4th 846 and expressly allows a finding of separation while the spouses live under one roof, as long as one spouse communicated that the marriage was over and both spouses' conduct was consistent with a final break.

Why does the date of separation matter for spousal support?

Family Code section 4336 presumes that a marriage of 10 years or more, measured from the wedding to the date of separation, is a marriage of long duration, which gives the court indefinite jurisdiction over spousal support. The length of the marriage is also a factor under Family Code section 4320, so a dispute over the separation date can change both the amount and duration of support.

What happens to income earned after the date of separation?

Under Family Code section 771, earnings and accumulations of a spouse while living separate and apart are that spouse's separate property. Income earned before separation is community property under Family Code section 760 and is divided equally under Family Code section 2550.

How do I prove my date of separation?

Gather the communication in which one spouse told the other the marriage was over, along with evidence of consistent conduct afterward, such as separated finances, a move-out or separate living arrangements, statements to family and friends, and the absence of shared vacations or marital activities. Present the chronology with exhibits in a declaration on FL-300 or FL-320, and use discovery to obtain the other spouse's records if the date will be tried.
