Financial Disputes in Divorce: What California Law Governs and How San Diego Courts Resolve Them

A contested money issue in a San Diego County divorce usually starts with something concrete: a spouse who has stopped sharing statements, a business valued at a number that seems wrong, a house one spouse owned before the wedding, or a support demand that does not match the household the couple actually lived in. Some readers are already in a case; others are still deciding whether to file. In either situation, knowing what the law requires makes it easier to judge which positions are worth pressing.

This page walks through that framework in order: how property is characterized and divided, what sworn financial disclosure demands, how spousal support is set, and how a financial dispute moves toward settlement or trial. In this setting, aggressive representation means preparation and a working command of these rules, so that a position can be proven in court if a negotiated outcome falls short.

Financial disputes in divorce fall into distinct legal categories, and each one has its own rules: property characterization and division, spousal support, debt allocation, and disclosure obligations. Child support is a related fight with its own formula, covered separately in the firm's guide to child and spousal support disputes.

The starting point for property is Family Code section 760. Its text reads: "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." Community property, in plain words, is what the marriage owns together. Under Family Code section 2550, the court divides the community estate equally, unless the parties agree otherwise in writing or by oral stipulation in open court, or another provision of the Family Code applies.

Separate property is what belongs to one spouse alone. Family Code section 770 says it includes all property owned before marriage; all property received during marriage by gift, bequest, devise, or descent (inheritance); and the rents, issues, and profits of that property. Separate property is not divided. Many of the hardest financial disputes are really arguments about which side of this line an asset falls on.

Timing matters too. Under Family Code section 2552, the court values the assets and debts as near as practicable to the time of trial, not the date of separation. On 30 days' notice and a showing of good cause, the court may value all or part of the estate at a date after separation and before trial, to achieve an equal division in an equitable manner.

In San Diego County, these disputes are decided by the Superior Court of California, County of San Diego. The state's statutes are available through the California Legislative Information site, and the court system's California Courts Self-Help Guide explains divorce procedure in general terms.

Section 2550's equal-division rule sounds simple, and the complications come from applying it to real assets. Equal division means the community estate as a whole is split in half by value; it does not mean each item is cut down the middle.

Mixed-character assets. An asset can be partly community and partly separate. A retirement account opened before the wedding and funded during it, or a home bought with a mix of premarital savings and marital earnings, are common examples. Sorting out the shares requires tracing: following the money back through account records to show where each dollar came from.

Separate-property reimbursement. Family Code section 2640 addresses one direction of mixing. When a spouse uses separate-property funds to acquire or improve community property, that spouse is reimbursed for the contribution, to the extent it is traced to a separate source, unless that spouse made a written waiver of the right or signed a writing with that effect. The section defines contributions to include down payments, payments for improvements, and payments that reduce loan principal, but not interest, maintenance, insurance, or taxes. Reimbursement is without interest or adjustment for inflation and cannot exceed the property's net value at division.

Moore/Marsden apportionment. The opposite situation is handled differently. When community funds pay down the loan on a home that is one spouse's separate property, California case law, known as the Moore/Marsden apportionment, gives the community a proportional interest in that home. The two doctrines are easy to confuse, but they run in opposite directions and produce different calculations.

Businesses. A business's value can include goodwill, and its value is decided on the evidence, often with experts on each side.

Retirement accounts and pensions. Retirement benefits earned during the marriage are community property. Dividing them typically requires a separate court order directed to the plan, in addition to the judgment itself.

Debts. Debts incurred during the marriage while domiciled in California are generally community debts, allocated as part of the equal division. Disputes over particular debts are taken up below.

Underneath all of this sits Family Code section 721, which makes spouses fiduciaries to each other in property matters. Each owes "a duty of the highest good faith and fair dealing," including access to books kept about a transaction and true and full information about anything affecting community property. Under Family Code section 1101, a spouse whose half-interest is impaired by a breach of that duty has a claim against the other, and the court may order an accounting of the parties' property and obligations.

Family Code section 2100 sets the purpose: "a full and accurate disclosure of all assets and liabilities in which one or both parties have or may have an interest must be made in the early stages of a proceeding," regardless of whether the property is community or separate, together with disclosure of all income and expenses. California carries this out in two stages, the preliminary declaration of disclosure and the final declaration of disclosure, each signed under penalty of perjury.

The preliminary declaration. Under Family Code section 2104(f), the petitioner serves it with the petition or within 60 days of filing the petition, and the respondent serves it with the response or within 60 days of filing the response. Those time periods may be extended by written agreement of the parties or by court order. The preliminary disclosure includes a schedule of assets and debts, which lists what each spouse owns and owes, and an income and expense declaration, which shows earnings and monthly spending. Together they are the factual map for the rest of the case.

The final declaration. Under Family Code section 2105(a), each party serves a final declaration of disclosure and a current income and expense declaration before or at the time the parties enter into an agreement resolving property or support issues other than temporary support, or, if the case goes to trial, no later than 45 days before the first assigned trial date. The parties may mutually waive the final declaration, but under section 2105(d) the waiver must be executed under penalty of perjury in open court or by separate stipulation.

When disclosure falls short. Family Code section 2107 lets a complying spouse request a missing or incomplete declaration. If the other spouse still does not comply, the complying spouse may file a motion to compel a further response, a motion to bar the noncomplying spouse from presenting evidence on issues the declaration should have covered, or a motion to waive receipt of the declaration for good cause, among other remedies. Section 2105(a) adds that perjury on the final declaration may be grounds for setting aside the judgment, or parts of it. California law also gives courts other remedies for concealment, which can include awarding the concealed asset, or the concealing spouse's share of it, to the other spouse. More on these remedies appears in the firm's page on a spouse hiding assets.

Lawful discovery. When the sworn disclosures do not add up, formal discovery is how the missing information is obtained: depositions (questioning under oath before a court reporter), subpoenas to banks and employers, and requests for production of documents. These tools come with court oversight. Logging into a spouse's accounts, devices, or messages is not one of them.

California recognizes two stages of spousal support. Temporary spousal support, sometimes called pendente lite support, is paid while the case is pending. Long-term or permanent support is ordered at judgment.

Temporary support can be ordered while the case is pending. Long-term support works differently: the court weighs the circumstances listed in Family Code section 4320. Those circumstances include the extent to which each party's earning capacity is sufficient to maintain the marital standard of living; the supported party's marketable skills, the job market for those skills, and the time and expense of education or retraining; the extent to which the supported party's earning capacity was impaired by unemployment during the marriage to handle domestic duties; the supported party's contribution to the other's education, training, career, or license; the supporting party's ability to pay, considering earning capacity, earned and unearned income, assets, and standard of living; and the needs of each party based on the marital standard of living. The section lists further circumstances as well; this list is partial.

In practice, the real dispute in a support case is often less about the factors than about the facts behind them: what someone actually earns, what they could earn, and what the household truly spent.

Length of marriage matters. Under Family Code section 4336, the court retains jurisdiction over support indefinitely in a marriage of long duration, unless the parties agree otherwise in writing or the court terminates support. There is a presumption that a marriage of 10 years or more, from marriage to separation, is of long duration, though the court may consider periods of separation, and a shorter marriage can also qualify. Section 4336(c) preserves the court's discretion to terminate support later on a showing of changed circumstances, and support orders generally can be modified on that showing.

A financially dependent spouse is not shut out of the courtroom. Family Code section 2030 requires the court to ensure each party has access to legal representation, including early in the case, and allows it to order one party to pay the other's reasonably necessary attorney's fees and costs based on income and needs. When a request is made, the court must make findings on disparity in access to funds and ability to pay; if the findings show both, the court shall award fees and costs.

Most financial disputes in San Diego County divorces end in a written agreement, usually a marital settlement agreement, before trial. Settlement is only as sound as the information behind it, which is why the final declaration of disclosure must be exchanged before or at the time a property or support agreement is made.

Private mediation and collaborative processes are voluntary options for working out financial terms. Custody is different: when custody or visitation is contested, Family Code section 3170 requires the court to set those issues for mediation, which in San Diego County is child custody recommending counseling with the court's Family Court Services, where the counselor may make a recommendation to the court. The firm's page on custody battles covers that process.

When money issues do not settle, the case is tried before a judge of the Superior Court of California, County of San Diego. There is no jury in a family law trial. Each side presents evidence: financial records, declarations, testimony, and often expert witnesses such as forensic accountants, business valuators, and real estate appraisers. Experts do not decide anything; their work is evidence the judge weighs before applying the statutes and making orders. The firm's overview of a divorce trial describes that stage in more detail.

The court can also bifurcate, meaning separate, issues. A common example is ending the marriage itself while reserving property and support for a later trial. Ending the marriage is still subject to a waiting period: under Family Code section 2339, no judgment of dissolution is final until six months have passed from the date the summons and petition are served or the date the respondent appears in the case, whichever occurs first. The period does not run from filing, and the court may extend it for good cause. The San Diego Superior Court's family law resources provide local procedural information.

Some cases carry features that make financial disputes harder to settle and harder to try.

Large or diverse estates. The more accounts, properties, and investments a community estate holds, the more disclosure, tracing, and expert valuation each one requires.

Business ownership. A closely held business or professional practice has no market price on a screen. Its value can include goodwill and is decided on the evidence, typically with competing expert analysis.

Stock options, RSUs, and deferred compensation. Equity awards that vest partly during and partly outside the marriage must be apportioned between community and separate shares, and the method chosen can change the result significantly.

Mixed-character real property. A home bought before marriage and paid down with community funds raises Moore/Marsden apportionment. A home bought with a mix of separate and community money raises section 2640 tracing and reimbursement. Both questions can arise in a single property.

Suspected hidden assets. When disclosure looks incomplete, subpoenas to financial institutions, depositions, and requests for production are the lawful means of finding out. The firm's page on hidden assets explains how those tools work in practice.

Debts. Student loans, business debts, and credit card balances incurred during the marriage may be community or separate depending on purpose and timing, and characterization is often contested.

Domestic violence and financial control. Abuse can include financial control, such as withholding access to money or records, and courts can consider that conduct. Anyone in immediate danger can call 911.

Financial disputes turn on details: when an account was opened, where a down payment came from, what a business actually earns, and whether a disclosure tells the whole story. A consultation is the place to walk through those facts, identify which rules (characterization, section 2640 reimbursement, section 4320 factors, or disclosure remedies) carry the most weight, and understand the procedural path from discovery to settlement conference to trial. The firm practises California family law only, so the conversation stays focused on how these California rules apply in a San Diego County case.
