California divorce law is different enough from most other states that advice found online is frequently wrong for San Diego. The state is a community property jurisdiction, it uses a statewide formula for child support, and it imposes a mandatory waiting period before any divorce can be finalised. Those three facts alone reshape most of the decisions a divorcing couple faces.
Here are the issues a San Diego divorce lawyer will work through with you, and why each one matters more than people expect.
Key Takeaways
- California is a community property state — assets and debts acquired during the marriage are generally divided equally.
- The date of separation is a critical legal fact because it fixes when community property stops accumulating.
- A divorce cannot be finalised until at least six months after the respondent is served or appears, no matter how quickly you agree.
- California abolished fault-based divorce; misconduct rarely affects the financial outcome.
- Automatic restraining orders take effect on filing and restrict what either spouse can do with assets and insurance.
Establishing the Date of Separation
This sounds procedural and is in fact one of the most contested issues in California divorces. Earnings, acquisitions and debts after the date of separation are generally separate property, so shifting the date by a few months can move a bonus, an equity vesting event, or a large purchase from one column to the other.
California courts look at whether there was a complete and final break in the marital relationship — expressed intent plus conduct consistent with it. Continuing to live in the same house does not automatically prevent separation, and moving out does not automatically establish it. Evidence such as messages, changed financial arrangements, and statements to friends and family becomes relevant.
Community Property Division
Everything acquired during the marriage from the labour or earnings of either spouse is presumptively community property, divided equally. Separate property — owned before marriage, or received by gift or inheritance — stays with its owner, unless it has been commingled or transmuted.
The complications are where lawyers earn their fee:
- The house. A property bought before the marriage but paid down with community earnings gives the community a reimbursement interest, calculated under established California formulas. Separate funds used for a community property down payment also generate a reimbursement right.
- Retirement and pensions. The community portion is the part earned during the marriage, and dividing an employer plan requires a Qualified Domestic Relations Order.
- Stock options and RSUs. Grants that vest across the separation date are apportioned under time-rule formulas, and this is often the largest single issue in San Diego tech and biotech households.
- A business. Where a business was separate property but grew through a spouse’s efforts during the marriage, California uses specific apportionment approaches to divide that growth. Valuation experts are usually necessary.
- Military pensions. San Diego’s large military population makes this routine — federal rules govern direct payment of retired pay and survivor benefit elections, and they interact with state law in ways that need specific handling.
- Debt. Divided along the same community lines, and a decree does not bind creditors, so joint accounts should be closed or refinanced.
Child Custody and Parenting Time
California decides custody on the best interests of the child, considering health, safety and welfare, any history of abuse or substance misuse, the nature and amount of contact with both parents, and the child’s wishes where they are of sufficient age and capacity. The state’s stated policy favours frequent and continuing contact with both parents where it is safe.
Contested custody cases in California go through mandatory mediation — in San Diego County this is handled through Family Court Services — before a judge decides anything. How you present in that session matters, and preparing for it is one of the more concrete things a lawyer does.
Legal custody, meaning decision-making about health, education and welfare, is separate from physical custody. Joint legal custody with an unequal timeshare is common. Move-away requests, where one parent wants to relocate with the children, are among the hardest cases in California family law and have their own body of case law — take advice before making any commitment to a move.
Child and Spousal Support
Child support in California is calculated by a statewide guideline formula driven principally by each parent’s net disposable income and the percentage of time each has the children. Courts use certified software, and departures from the guideline figure are limited. Because timeshare is an input, custody and support are financially linked — which is worth understanding before positions harden.
Add-ons are ordered separately: childcare needed for work, uninsured medical costs, and sometimes education or special needs expenses, typically shared between the parents.
Spousal support works differently. Temporary support during the case is often set by a local guideline formula, but long-term support after judgment must be determined by reference to the statutory factors in Family Code section 4320 — marital standard of living, earning capacity, contributions to the other spouse’s education or career, age and health, and documented domestic violence, among others. For marriages under ten years, courts commonly set support at around half the length of the marriage; for marriages of ten years or more the court generally retains jurisdiction without setting a fixed termination date. Support can also be reduced over time where the supported spouse is expected to become self-supporting.
Disclosure Obligations
California imposes an unusually strict duty. Both spouses must serve preliminary and final declarations of disclosure listing all assets, debts, income and expenses, and the duty is fiduciary — the same standard business partners owe each other. Failure to disclose has real consequences: California courts have set aside judgments and awarded concealed assets to the other spouse.
Filing also triggers automatic temporary restraining orders binding on both parties. They prohibit transferring or disposing of property outside the ordinary course, changing insurance beneficiaries, and removing children from the state without consent or a court order. People violate them unknowingly all the time — read them before you do anything with an account or a policy.
Timeline and Process
You must have lived in California for six months and in San Diego County for three months before filing there. From the date the respondent is served or appears, a minimum six-month waiting period runs before the marriage can be terminated — even in a fully agreed case. Complex or contested matters take considerably longer.
Not every case needs litigation. Mediation and collaborative divorce work well where both spouses will disclose honestly, and they are usually faster and cheaper. Where there is abuse, concealment, or a spouse who will not engage, court process becomes necessary. A firm such as Contreras Law Firm will normally assess which route fits at the first meeting.

What People Overlook
- Health insurance. Coverage under a spouse’s employer plan ends at judgment. Plan for COBRA or a marketplace policy before that date.
- Tax consequences. Filing status, which parent claims the children, capital gains on a house sale, and the fact that alimony under post-2018 agreements is not deductible federally.
- Estate documents. Wills, trusts, powers of attorney and non-retirement beneficiary designations all need revisiting — subject to the automatic restraining orders on timing. The same legal process applies as in estate planning generally.
- Attorney fee orders. California allows need-based fee awards so that a lower-earning spouse is not outmatched, which people frequently do not know they can request.
Frequently Asked Questions
Does adultery affect the outcome in California?
Generally not. California is a pure no-fault state and misconduct is not a ground for unequal division or for support. It can become relevant indirectly — for example if community funds were spent on an affair, which may support a reimbursement claim.
Is everything really split 50/50?
Community property is divided equally in value, but that does not mean every asset is halved. Assets are commonly allocated whole and offset against each other. Separate property is not divided at all, and characterisation is where most disputes live.
Can we finish faster than six months?
No. You can resolve every issue and file the judgment sooner, but the termination of marital status cannot take effect before the statutory period expires.
What if my spouse is in the military and deployed?
The Servicemembers Civil Relief Act can allow a stay of proceedings during deployment, and military pensions, healthcare and survivor benefits raise federal issues. Given San Diego’s military community, this is common — use a lawyer who handles it regularly.
Can a support order be changed later?
Child support is always modifiable on a change of circumstances. Spousal support is modifiable unless the parties agreed it is non-modifiable, which is a term worth understanding fully before signing.
The Bottom Line
The issues that decide a San Diego divorce are mostly technical rather than emotional: the date of separation, characterisation of property, apportionment of a business or equity compensation, the timeshare percentage driving support, and complete disclosure. Getting those right at the start is far cheaper than correcting them later.
