What Is Community Property?

(And Why It Matters in California Estate Planning)

If you are married in California, the term community property affects nearly everything you own.

It determines:

• Who owns what during marriage

• What happens at death

• What happens in divorce

• How property receives tax treatment

Yet many couples are unclear about what actually qualifies as community property - and what does not.

Let’s break it down simply.

California Is a Community Property State

California follows community property law, which is codified in part in the California Family Code.

The basic rule: Assets acquired during marriage are generally owned equally by both spouses.

That means each spouse owns a one-half interest, regardless of whose name is on title.

Title does not necessarily determine ownership.

Timing and source of funds matter more.

What Is Community Property?

Community property generally includes:

• Income earned by either spouse during marriage

• Real estate purchased during marriage (unless separate funds were used)

• Retirement contributions made during marriage

• Businesses started during marriage

• Assets purchased with marital earnings.

If it was acquired during marriage with marital earnings, it is likely community property.

What Is Separate Property?

Separate property generally includes:

• Assets owned before marriage

• Inheritances received individually

• Gifts made to one spouse

• Assets acquired after permanent separation.

However, separate property can become mixed (“commingled”) with community property over time.

For example:

• Depositing inheritance funds into a joint account

• Using separate funds for a marital down payment without documentation

• Refinancing property and changing title.

When documentation is lost or commingling occurs, classification disputes can arise.

Why Community Property Matters at Death

Community property has unique tax advantages.

When one spouse dies:

• The surviving spouse receives a full step-up in basis on community property

• This applies to both halves - not just the deceased spouse’s half.

This can significantly reduce capital gains taxes if property is later sold.

By contrast, separate property generally receives a step-up only on the deceased spouse’s portion.

This tax treatment often makes preserving community property classification advantageous.

What Happens Without an Estate Plan?

If one spouse dies without a trust or will, distribution is governed by the California Probate Code.

In many cases:

• The surviving spouse retains their one-half of community property

• The deceased spouse’s half may pass according to intestacy rules.

The result can be different depending on whether there are children from the marriage or from prior relationships.

Blended families create additional complexity.

Titling Matters — But It Isn’t Everything

How property is titled can affect presumptions.

For example:

• “Community Property with Right of Survivorship” provides automatic transfer at death.

• Joint tenancy has different tax implications.

But title alone does not override the underlying character of the funds used to acquire the property.

Proper documentation and planning help avoid confusion later.

Common Misunderstandings

“If It’s in My Name, It’s Mine.”

Not necessarily. If it was earned or acquired during marriage, your spouse may own half - even if their name is not on title.

“We Always Kept Separate Accounts, So It’s Separate Property.”

Separate accounts do not automatically mean separate property. If the funds were earned during marriage, they are likely community property.

“Community Property Means We Can’t Control Where It Goes.”

You still control your half of community property in your estate plan. However, your spouse’s half is theirs to control. This becomes especially important in second marriages.

Why This Matters in Estate Planning

Understanding community property helps with:

• Trust drafting

• Asset allocation

• Beneficiary coordination

• Tax planning

• Avoiding disputes among heirs.

Misunderstanding classification is one of the most common causes of conflict after death - particularly in blended families.

The Bottom Line

In California:

• Assets acquired during marriage are generally community property.

• Each spouse owns an equal one-half interest.

• Community property receives favorable tax treatment at death.

Because classification can affect ownership, taxes, and inheritance outcomes, it is worth reviewing how your assets are characterized.

Estate planning works best when it reflects how your property is legally owned - not just how you assume it is.

Clarity now prevents confusion later.
