Discovery in Divorce: A Step-by-Step Guide for San Diego County

This page is for a spouse in a contested San Diego County divorce who has opened the other side's financial disclosure and found it thin. The numbers may not match the life the two of you lived. A business may seem to be earning less than it did. Accounts you remember may be missing. Most people facing this process have never heard the words "interrogatory" or "deposition subpoena." They are trying to work out two things: what they can lawfully do to get the real picture before trial, and how long it will take.

For a person looking for an aggressive family law attorney in a contested case, discovery is often where that kind of advocacy actually happens. It is not about hostility. It is about preparation, precise requests, follow-through when answers come back incomplete, and a readiness to ask the Superior Court of California, County of San Diego to enforce the rules. The guide below covers five steps: gathering existing records, serving formal requests, reviewing responses, subpoenaing third parties and exchanging expert information. It then covers timing and the complications that tend to lengthen the process.

What discovery covers. Under Code of Civil Procedure section 2017.010, a party may obtain discovery about any matter that is not privileged and that is relevant to the case, if the matter is admissible or appears reasonably calculated to lead to admissible evidence. "Privileged" means legally protected from disclosure, such as attorney-client communications. Discovery can reach documents, electronically stored information and property. It can also identify people who know something relevant. These Code of Civil Procedure tools generally apply in family law cases.

Mandatory disclosure comes first. Discovery is different from the mandatory disclosures that every divorcing spouse must make. Family Code section 2100 explains why those disclosures exist. California's policy is to preserve the community estate, ensure fair support awards, and reduce conflict by fostering full disclosure and cooperative discovery early in the case.

There are two required disclosures:

• Preliminary declaration of disclosure. Under Family Code section 2104(f), the petitioner serves it with the petition or within 60 days of filing the petition. The respondent serves it with the response or within 60 days of filing the response. The parties may extend that time by written agreement, or the court may extend it by order.
• Final declaration of disclosure. Under Family Code section 2105(a), the final declaration and a current income and expense declaration are due before or at the time the parties agree on property or support issues other than temporary support. If the case goes to trial, they are due no later than 45 days before the first assigned trial date. Both are executed under penalty of perjury.
• Waiving the final declaration. The parties may mutually waive the final declaration. That waiver, which must include the representations the statute requires, is executed under penalty of perjury in open court or by separate stipulation (Family Code section 2105(d)).

Where discovery fits. Formal discovery is the additional layer a party may choose to use. It matters most when one spouse controlled the finances, when assets are complex, or when the mandatory disclosures appear incomplete. Readers dealing with a spouse hiding assets usually reach this point after the preliminary disclosures have been exchanged.

This step costs little more than time, and it shapes every request that follows. Before serving anything formal, a spouse in San Diego County typically collects the records already in their own lawful possession. These include:

• tax returns
• bank and credit card statements
• pay stubs
• retirement account statements
• mortgage statements
• loan applications
• business records the spouse already has legitimate access to

Why the marriage dates matter. Family Code section 760 defines community property as property acquired during the marriage while domiciled in California. "Domiciled" means California was the spouse's legal home. Because of that definition, records from the date of marriage forward tend to be relevant.

Why recent records matter too. Family Code section 2552 directs the court to value the community estate as near as practicable to the time of trial. On 30 days' notice, the court may for good cause use a date after separation and before trial. Because of that rule, recent records matter as much as old ones.

Two tracing questions. Older records can matter in two different situations:

• Separate money into community property. Family Code section 2640 reimburses a spouse who traces contributions to a separate-property source. Examples include a down payment, improvements, or principal paydown on community property, but not payments of interest on the loan or payments for the property's maintenance, insurance or taxation; reimbursement is capped at the property's net value at the time of division. The right to reimbursement is lost if the spouse signed a written waiver or a writing that has the effect of a waiver. Proving the source often requires records that predate the marriage.
• Community money into separate property. The Moore/Marsden apportionment addresses the opposite situation: community funds paid down a loan on one spouse's separate-property home. Mortgage payment histories are the core evidence for that claim.

What not to do. Gathering records does not mean logging into the other spouse's email, financial accounts or phone. Penal Code section 632 generally prohibits recording a confidential conversation without the consent of everyone in it, subject to limited statutory exceptions. Evidence obtained improperly can create problems of its own. The lawful routes for getting what is missing are the formal tools in the steps below.

Code of Civil Procedure section 2019.010 lists the discovery methods:

• oral and written depositions
• interrogatories to a party
• inspections of documents, things and places
• physical and mental examinations
• requests for admissions
• simultaneous exchanges of expert trial witness information

In a San Diego County family law case, the most common tools are described below.

• Form interrogatories. These are standardized written questions, including a family law set, that the other party must answer under oath.
• Special interrogatories. These are custom written questions drafted around the specific facts of the case, such as a particular business, account or transfer.
• Requests for production (inspection demands). These are written demands for specific records, including statements, business ledgers and communications.
• Requests for admission. These are written statements the other party must admit or deny. They are useful for taking undisputed facts off the table before trial.
• Depositions. A deposition is a sworn oral examination of a party or witness, taken before a court reporter and outside the courtroom.

Response deadlines. Under Code of Civil Procedure sections 2030.260 and 2031.260, responses to interrogatories and to inspection demands are due within 30 days after service. The court may shorten that time on motion of the requesting party or extend it on motion of the responding party.

Third parties are a separate track. Subpoenas to people outside the case, such as banks and employers, work differently from requests to the other spouse. They are covered in Step 4.

The cost of this step depends on how many requests are needed and how contested the issues are.

Response day can be its own kind of disappointment. A long-awaited packet may arrive full of objections instead of answers.

Common objections. An objection is a stated legal reason for refusing to answer. The most common are:

• Privilege: the information is legally protected.
• Relevance: it has nothing to do with the case.
• Burden: answering would be unreasonably costly or oppressive.

Discovery misuse. Code of Civil Procedure section 2023.010 lists misuses of discovery, including failing to respond, making evasive responses, making unmeritorious objections without substantial justification, and disobeying a court order to provide discovery. The same section also lists misuse by the requesting side. Examples include requests that cause unwarranted annoyance, oppression or undue burden, and persisting in seeking material outside the scope of discovery. Overuse is addressed in the page on litigation abuse in family court.

Meet and confer, then a motion to compel. When responses are incomplete, the parties generally must first meet and confer. That means a good-faith attempt to resolve the dispute informally before asking the court for help. If that fails, a motion to compel further responses asks the Superior Court of California, County of San Diego to order complete answers.

Sanctions. Code of Civil Procedure section 2023.030 allows the court, after notice and an opportunity for a hearing, to order a party who misuses discovery, or the attorney advising that conduct, or both, to pay the reasonable expenses caused, including attorney's fees. The court may also sanction a party who unsuccessfully claims the other side misused discovery.

Planning the next requests. Gaps in the responses often point to the next request. A business's value can include goodwill, and that value is decided on the evidence, often with experts. Thin business records may therefore lead to subpoenas and forensic accounting work. How far back the requests reach depends on what is at issue. Community property spans the marriage while domiciled in California, so records from the date of marriage through close to trial may be relevant. The question of how far back financial discovery goes is covered separately.

A deposition subpoena for business records lets a party get documents directly from a bank, employer, brokerage, retirement plan administrator or other institution, without relying on the other spouse's cooperation.

What the subpoena must say. Under Code of Civil Procedure section 2020.410, the subpoena must designate the records either by specifically describing each item or by reasonably particularizing each category. It must also specify the form for electronically stored information if a particular form is wanted. Identifiers known only to the institution's own system, such as a policy number, are not required. A records-only subpoena does not need a declaration showing good cause. It is directed to the custodian of records or another person qualified to certify them. The institution must also be given a reasonable time to comply.

Consumer notice. Code of Civil Procedure section 1985.3 adds protections when the records are "personal records" of a consumer held by covered institutions, such as banks, credit unions, brokerage firms and insurance companies. The consumer must receive notice and has an opportunity to object before the records are produced.

Records-only versus appearance. A records-only subpoena asks for documents. A deposition subpoena requiring personal appearance compels a witness to come and testify under oath, sometimes with documents.

In San Diego County divorce cases, subpoenas commonly reach bank records, retirement account records, business financial records and employment income records. For income questions in particular, see proving hidden income.

When the value of property or a business, or a spouse's ability to pay support, is genuinely disputed, each side may retain and designate expert witnesses.

The exchange. Code of Civil Procedure section 2019.010(f) lists the simultaneous exchange of expert trial witness information as a discovery method. After that exchange, the experts themselves may be deposed.

Common experts. Typical experts include:

• Forensic accountants, who value businesses and trace separate property.
• Real estate appraisers, who value homes and other real property.
• Vocational evaluators, who assess earning capacity for support purposes.

Tracing work. Tracing experts often address both property questions from Step 1:

• the section 2640 reimbursement claim, which applies when separate money went into community property and no written waiver was signed
• the Moore/Marsden apportionment, which applies when community money paid down a separate-property home loan

Business value. Where a business is involved, its value, including any goodwill, is decided on the evidence presented.

Expert work is often the largest variable in the overall cost of discovery. It is driven by the volume of records and the number of disputed questions. Readers concerned about concealment more broadly may find the overview of hidden assets useful.

Typical timeline

The six-month period. Under Family Code section 2339, a judgment of dissolution is not final for the purpose of terminating the marriage relationship 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 court may extend that period for good cause. Discovery often runs during the same period.

How long discovery takes. A straightforward exchange may conclude within a few months. Contested discovery, with motions to compel, third-party subpoenas and expert exchanges, can extend a case considerably.

Trial deadlines. Two deadlines anchor the end of the process:

• Code of Civil Procedure section 2024.020 generally entitles a party to complete discovery by the 30th day before the date initially set for trial, and to have discovery motions heard by the 15th day before that date. A continuance of the trial date generally does not reopen discovery.
• The final declaration of disclosure is due no later than 45 days before the first assigned trial date (Family Code section 2105(a)).

Discovery that is not substantially complete before those dates is of limited use at trial.

When the process gets complicated

A family business. Business records, owner compensation and value each become their own discovery project.

Separate-property tracing. Older records, sometimes from before the marriage, may be needed.

Retirement or deferred compensation. Plan administrators often have to be subpoenaed for complete records.

Mixed-timing real property. A home bought partly before and partly during the marriage raises both reimbursement and apportionment questions.

Contested custody. When custody or visitation is contested, Family Code section 3170 requires the court to set those issues for mediation. In San Diego County that mediation is child custody recommending counseling with the court's Family Court Services. Under Family Code section 3183, the counselor may, consistent with local court rules, make a recommendation to the court if it is first provided in writing to the parties and their attorneys. Family Court Services states that if no agreement is reached, the counselor makes a recommendation and the hearing proceeds. Domestic violence cases follow a separate written protocol approved by the Judicial Council (section 3170(b)). That process runs on its own track, alongside financial discovery. The broader shape of a contested divorce covers how these tracks fit together.

Discovery decisions are rarely generic. What to request, from whom, and how far back depends on when the marriage began, where the money moved, whether a business or separate property is involved, and how close the trial date is. A consultation with the firm can cover:

• which records already exist
• where the disclosures appear to fall short
• which tools fit those gaps
• how the 30-day response rules and pretrial cutoffs affect the case's calendar
