Dividing property in a divorce can be one of the most complex and contentious aspects of the process. California's community property system creates specific rules about what belongs to whom, but the application of these rules to real-world situations requires careful analysis. At By The Law Group APC, we help clients protect their assets, trace separate property, and achieve fair divisions that reflect their contributions and needs.

California Community Property Law

Fam. Code §760 Except as otherwise provided by statute, all property, real or personal, wherever situated, acquired by a married person during the marriage while domiciled in this state is community property.

Property Types

Community vs. Separate Property

Community Property

Property acquired during marriage that belongs equally to both spouses and is divided equally upon divorce.

Examples:

  • Income earned by either spouse during marriage
  • Real estate purchased during marriage
  • Retirement contributions made during marriage
  • Businesses started during marriage
  • Vehicles purchased during marriage
  • Furniture and household items acquired during marriage

Equal Division: Community property is divided equally (50/50) in divorce unless the parties agree otherwise.

Separate Property

Property that belongs solely to one spouse and is not subject to division in divorce.

Examples:

  • Property owned before marriage
  • Inheritances received during marriage
  • Gifts to one spouse during marriage
  • Income from separate property
  • Property acquired after separation
  • Personal injury awards (with exceptions)

Tracing Required: Separate property claims must be proven with clear documentation tracing the asset's origin.

Complex Issues

Commingling & Tracing

When Separate Becomes Community

Separate property can become community property (or partially community property) through:

Commingling

Mixing separate funds with community funds in the same account.

Transmutation

Written agreement changing property's character (e.g., adding spouse to title).

Community Property Contributions

Using community funds to improve or pay down debt on separate property.

Tracing Separate Property

To prove an asset is separate property, you must trace its origin through documentation:

  • Bank statements showing pre-marital balance
  • Deeds showing acquisition date
  • Inheritance documents
  • Gift documentation
  • Loan documents
  • Appraisals at date of marriage
Moore-Marsden Calculation

When community funds pay down principal on a separate property home, the community may be entitled to a portion of the appreciation.

Asset Types

Special Property Considerations

The family home is often the most significant asset. Issues include:

  • Date of Acquisition: Before or during marriage determines characterization
  • Mortgage Payments: Community payments on separate property create reimbursement claims
  • Improvements: Community-funded improvements may create community interest
  • Buyout vs. Sale: One spouse may buy out the other's interest, or the property may be sold

Fam. Code §760 Retirement benefits earned during marriage are community property. Division requires:

  • QDRO: Qualified Domestic Relations Order for 401(k)s and pensions
  • IRA Transfers: Direct rollover to avoid tax consequences
  • Defined Benefit Plans: Present value calculation or future benefit division
  • Social Security: Not divisible, but may affect spousal support

Businesses started during marriage are community property. Valuation considerations:

  • Valuation Date: Date of separation vs. trial date
  • Goodwill: Personal vs. enterprise goodwill
  • Double Dipping: Counting business income for both property division and support
  • Buyout Options: Structured payments vs. lump sum

Stock options and restricted stock units granted during marriage are generally community property. The analysis considers:

  • Grant date vs. vesting date
  • Time-based allocation formulas
  • Performance-based vesting conditions
  • Tax consequences of division
Debt Division

Dividing Debts in Divorce

Just as assets are divided, debts must be allocated between spouses. California follows similar principles for debt as for property:

Community Debt

Debts incurred during marriage, regardless of whose name is on the account.

  • Mortgages on family home
  • Credit card balances
  • Car loans
  • Personal loans
  • Tax debts

Separate Debt

Debts incurred before marriage or after separation.

  • Student loans (generally)
  • Pre-marital credit card debt
  • Debts incurred after separation
  • Debts for non-marital purposes
Creditor Rights

Important: Your divorce judgment divides debts between you and your spouse, but creditors are not bound by it. If your ex-spouse fails to pay a joint debt, creditors can still pursue you. Consider refinancing joint debts into individual names when possible.
