When people hear that California is a community property state, they often assume that divorce means everything they own will be divided 50/50.

That isn't quite how it works.

California does generally divide community property equally, but not every asset a married couple owns is community property. Property that belongs to one spouse separately is generally not divided in the divorce. The difficult part is often determining what is truly separate, what belongs to the community, and what has become a mixture of both.

For couples with real estate, businesses, investments, retirement accounts, inheritances, or other significant assets, those distinctions can have a major effect on the final settlement.

California Family Code Section 760 provides that property acquired by a married person during the marriage while domiciled in California is generally community property unless another law says otherwise.

In practical terms, income earned during the marriage and property purchased with that income will ordinarily belong to both spouses, even when an account, vehicle, or other asset is held in only one spouse's name.

Separate property is different. In general, each spouse keeps his or her separate property rather than dividing it with the other spouse.

So what falls into that category?

Property you already owned before the marriage is generally your separate property.

That might include a house purchased years before the wedding, an investment account you had already built, a vehicle you owned outright, or an interest in a business you started before getting married.

California Family Code Section 770 specifically identifies property owned before marriage as separate property.

But ownership at the beginning of the marriage isn't always the end of the analysis.

Suppose you owned a house before marriage but spent community income paying down the mortgage for the next 15 years. The house may still have a separate-property component, but the community may also acquire an interest or reimbursement claim.

The same problem can arise with businesses and investment accounts.

This is why the question is often not simply, "Whose name is on it?" The more important question is where the money came from and what happened to the asset during the marriage.

An inheritance received by one spouse is generally separate property, even when it arrives in the middle of a marriage.

The same rule generally applies to a gift made specifically to one spouse.

For example, if your father leaves you $300,000 in his estate while you are married, the fact that you were married when you received the money does not automatically give your spouse a 50% interest in it. Family Code Section 770 treats property acquired by gift, bequest, devise, or descent as separate property.

What happens after you receive it, however, matters.

If the inheritance stays in an account in your name and there are good records showing where the money came from, its separate character may be relatively easy to establish.

If the money is deposited into accounts containing years of marital income, moved repeatedly between accounts, or used to acquire jointly held assets, tracing the separate-property portion can become considerably more complicated.

Commingling does not automatically make separate property disappear. But poor records can make proving a separate-property claim much harder.

The date of separation can have enormous financial consequences in a California divorce.

Under Family Code Section 771, a spouse's earnings and accumulations after the date of separation are generally that spouse's separate property.

California defines the date of separation as the point when there has been a complete and final break in the marital relationship. One spouse must have communicated an intent to end the marriage, and that spouse's actions must be consistent with that intent.

That is not always the day someone moves out.

A couple may continue living in the same house after separating. In another case, one spouse may move out temporarily without actually intending to end the marriage.

When significant income, bonuses, stock compensation, business revenue, or investments are involved, a dispute over a few months of separation can translate into a substantial amount of money.

There is another important distinction here: property purchased after separation is not automatically separate merely because it was purchased later. The source of the money used to acquire it can still matter.

Personal injury settlements are more complicated than many people realize.

If the cause of action arose during the marriage, California Family Code Section 780 generally characterizes the recovery as community property rather than automatically treating it as separate property.

That does not mean the settlement is simply divided in half.

Family Code Section 2603 provides special rules for personal injury damages when spouses divorce. Generally, the damages are assigned to the spouse who suffered the injury. A court can order a different allocation when the interests of justice require it, although the injured spouse must receive at least half.

If the injury occurred after separation or after a judgment of dissolution or legal separation, different rules apply, and the recovery may be the injured spouse's separate property.

Because timing and the nature of the recovery matter, personal injury settlements should be reviewed individually rather than placed into the same category as an inheritance or premarital asset.

A valid agreement between spouses can also change how property is treated.

A prenuptial agreement, for example, may establish that a business, investment portfolio, real estate holdings, future income, or another asset will remain separate property.

California imposes specific requirements on premarital agreements. Among other things, enforceability can depend on proper financial disclosure, whether the agreement was entered into voluntarily, whether each party had appropriate access to independent legal counsel, and whether required waiting periods were followed.

Postmarital agreements can also affect property rights, but they raise different legal issues and should not simply be treated as interchangeable with prenups.

For couples who already have an agreement, the agreement itself needs to be reviewed before making assumptions about what is or is not subject to division.

Retirement accounts frequently contain both separate and community property.

Imagine someone begins contributing to a retirement plan at age 28, gets married at 38, separates at 53, and retires years later.

The marriage does not automatically convert the entire retirement benefit into community property.

Generally, retirement benefits attributable to employment or contributions during the marriage and before separation are community property. Benefits earned before marriage or after separation generally remain separate.

Exactly how the community and separate portions are calculated depends on the type of retirement plan.

Defined-benefit pensions are often divided using a "time rule" that looks at the period of service during the marriage compared with total service. A 401(k), IRA, or similar account may require a different tracing and valuation analysis.

With long marriages and large retirement balances, this can become one of the more significant financial issues in the divorce.

Calling an asset "separate property" does not always mean the analysis is finished.

Money moves. Houses are refinanced. Businesses grow. Accounts are combined. Titles change. Marital earnings are used to improve assets that one spouse owned before the marriage.

Consider an inheritance.

One spouse receives $200,000 and leaves it untouched in a separate account. Twenty years later, bank records still show exactly where it came from.

Compare that with receiving the same $200,000, depositing it into the couple's primary checking account, using some of it for a house remodel, moving another portion to a brokerage account containing marital earnings, and then using part of that account to purchase another property.

The original money may have started as separate property in both cases. Proving what happened to it is dramatically easier in the first.

California also has specific rules governing agreements or transfers that change property from separate to community, community to separate, or from one spouse's separate property to the other's. These are known as transmutations, and Family Code Section 852 generally requires a written express declaration for a valid transmutation.

That is one reason titles, agreements, account statements, purchase documents, and financial records can become so important in a high-asset divorce.

This deserves separate attention because it is one of the most common sources of confusion.

Owning the house before the wedding does not necessarily mean your spouse gets half of it.

But it also does not always mean the community has no claim whatsoever.

If community earnings were used during the marriage to pay down principal on the mortgage, the community may acquire an interest in the property. Refinancing, adding a spouse to title, making substantial improvements with marital money, and other transactions may affect the analysis as well.

Real estate owned before marriage is therefore often partly a tracing problem and partly a valuation problem.

For couples with substantial equity, the difference can be significant.

Mediation does not change California property law.

What it can change is how spouses deal with disagreements about that law.

A complex-property divorce still requires identifying assets, determining when and how they were acquired, reviewing documentation, valuing property when necessary, and distinguishing legitimate legal disputes from issues that are already fairly clear.

The difference is that those questions can be addressed as part of a settlement process rather than immediately turning each disputed asset into a separate courtroom fight.

For financially complex divorces, that can be especially useful.

A couple may agree that an inheritance is separate property, for example, while disagreeing about whether part of a business increased in value because of marital efforts. Resolving the first issue allows everyone to spend their time and resources on the issue that actually needs negotiation.

Marla Keenan-Rivero brings more than two decades of California family law experience to divorce mediation, including matters involving significant assets and complicated financial issues.

Her mediation practice helps couples work through questions involving separate and community property, real estate, retirement benefits, businesses, support, and other financial concerns without automatically placing those decisions in the hands of a judge.

In a high-asset divorce, the goal is not simply to put every asset into two columns.

The goal is to understand what the law says, determine what the financial records actually show, identify the areas where reasonable disagreement exists, and develop a settlement both spouses understand before they sign it.
