A California divorce is, at its heart, a financial event. The legal process matters, but most of the decisions that shape your next ten years are about money: who keeps the house, how retirement accounts are split, whether support is paid and for how long. This guide walks through how California handles each of those questions so you can plan with a clear head instead of guessing.
California is a community property state: what you earned and acquired during the marriage is split 50/50. Spousal support has no fixed formula for the long term, but a marriage of 10 years or more keeps the court involved indefinitely. Child support follows a statewide formula that was overhauled in 2024, and the tax treatment of support changed for orders dated 2026 onward.
How California divides property
California is a community property state, which works differently from the "equitable distribution" rule in most other states. Under Family Code 760, almost everything either spouse earns or acquires during the marriage, while living in California, belongs to both of you equally, no matter whose name is on the account or title. Under Family Code 2550, the court must divide that community estate equally, 50/50. A judge does not weigh what feels "fair." The only route to a different split is a written agreement between the two of you.
Community vs. separate property
Separate property stays with its owner and is not divided. Under Family Code 770, that means anything you owned before the marriage, plus gifts and inheritances received by you alone. The dividing line is timing: property acquired between the date of marriage and the date of separation is presumed community.
The complication most people miss is commingling. If you mix separate money with marital money, or use marital earnings to pay down a premarital mortgage, part of that asset can become community property. Keeping clear records of where separate property came from is often what decides whether you keep it.
The house, the retirement accounts, and the debts
The two biggest assets in most divorces are the family home and retirement savings. Retirement contributions made during the marriage are community property even if the account is in one spouse's name, and dividing certain accounts takes a separate court order so the transfer is not taxed as an early withdrawal. Debts work the same way: most debts taken on during the marriage are community debts and are divided equally too. Trading the house for the retirement account is a common move that can quietly cost a great deal if the after-tax values are not compared properly. Modeling these trade-offs before you agree to anything is exactly the kind of decision Your Divorce Angel is built to help you see clearly.
Spousal support
California handles support in two stages, and they work very differently.
Temporary vs. long-term support
- Temporary support — paid while the divorce is still in progress. Most counties use a guideline formula to set it, so the number is fairly predictable.
- Long-term support — decided at the end of the case. There is no formula. The court weighs the factors in Family Code 4320: the standard of living during the marriage, each spouse's earning capacity, the length of the marriage, age and health, and the contributions each made.
The "10-year rule"
Marriage length is the single biggest factor in how long support lasts. Under Family Code 4336, a marriage of 10 years or more, measured from the date of marriage to the date of separation, is presumed to be of "long duration." In those cases the court keeps jurisdiction indefinitely, meaning there is no automatic end date on support. This does not guarantee lifetime payments, but it removes the built-in cutoff.
For marriages under 10 years, the common guideline is that support lasts about half the length of the marriage, so a court might order support for roughly four years after an eight-year marriage. That is a starting point, not a rule, and the court keeps discretion.
For spousal support orders dated January 1, 2026 or later, support is not tax-deductible for the person paying and not taxable income for the person receiving it, at both the federal and California state level. California recently conformed to federal law under Senate Bill 711. This ended a long stretch where California uniquely still allowed a state deduction, and it changes the real value of every support dollar, so pre-tax and after-tax figures should never be confused at the negotiating table.
Child support
California calculates child support with a mandatory statewide guideline formula under Family Code 4055, based on both parents' net incomes and the percentage of time each parent spends with the children. In September 2024, Senate Bill 343 overhauled this formula for the first time in over 30 years: it updated the income brackets, expanded protections for lower-income parents, and made proportional sharing of add-on costs such as childcare and medical expenses the default, based on each parent's share of income rather than an automatic 50/50 split. If you have an older order, it may be worth checking whether the new formula changes your number.
The financial timeline
Two things people consistently underestimate: how long the process takes and how much costs rise once you are running a household alone. To file in California, one spouse must have lived in the state for 6 months and in the filing county for 3 months. And no divorce becomes final until at least six months and one day after the responding spouse is served, no matter how fast you agree. A realistic financial sequence:
- Before filing — gather a complete picture of assets, debts, income, and expenses, and pin down the date of separation. Every later decision rests on these.
- Temporary phase — temporary support and living arrangements while the case proceeds.
- Disclosure and negotiation — California requires both sides to exchange full financial disclosures; settlement scenarios get modeled and compared.
- Settlement or trial — most California divorces settle. The ones that go to trial cost more and hand the decisions to a judge.
- After the judgment — support, the equal division, and any account transfers are carried out.

Questions worth asking before you negotiate
- What is the full community estate, and which assets are actually separate property?
- Has separate property been commingled in a way that could make part of it community?
- If we trade the house for the retirement account, are we comparing after-tax values?
- Given our marriage length, will the court keep jurisdiction over support indefinitely?
- What will my true monthly cost of living be once I am on my own, and what does each scenario look like five and ten years out?
California divorce: common questions
Is California a community property state?
Yes. Property acquired during the marriage is community property and is divided equally, 50/50 (Family Code 760 and 2550). Separate property, owned before marriage or received by gift or inheritance, generally stays with its owner (Family Code 770).
How is spousal support calculated?
Temporary support is usually set by a county guideline formula. Long-term support has no formula and is based on the factors in Family Code 4320, such as standard of living, earning capacity, and length of the marriage.
What is the 10-year rule?
Under Family Code 4336, a marriage of 10 years or more is presumed long duration, and the court keeps jurisdiction over support indefinitely, with no automatic end date. It does not guarantee lifetime support. Under 10 years, support commonly lasts about half the marriage length.
How is child support calculated?
By a statewide guideline formula (Family Code 4055) based on both parents' incomes and time with the children. Senate Bill 343, effective September 1, 2024, updated the formula and made proportional sharing of add-on costs the default.
Is spousal support taxable?
For orders dated January 1, 2026 or later, support is not deductible by the payer and not taxable to the recipient, for both federal and California taxes, under Senate Bill 711. Orders from 2019 to 2025 followed a split federal and state treatment.
How long does a California divorce take?
It cannot be final until at least six months and one day after the responding spouse is served (Family Code 2339), and many take longer.
