Prepare by turning every disputed issue into a short proof plan: what the court must decide, what facts support your position, which admissible evidence proves those facts, and what deadline governs the evidence. Then organize witnesses, exhibits, testimony, and logistics around the judge’s orders. A family-law trial is not a general opportunity to tell the whole relationship story; it is a structured presentation of the issues properly before the court.
1. Identify the decisions the judge must make
Start with the operative pleadings, requests for order, prior orders, trial-setting documents, and any statement of issues or trial brief requirement. List each requested decision separately—for example, custody and parenting time, support, characterization or division of property, reimbursement, fees, or enforcement. For each issue, write:
- The order you want.
- The facts that matter under the governing legal standard.
- The evidence supporting each material fact.
- The evidence the other side may use.
- The remedy or calculation the court would need to make.
This prevents a common preparation error: collecting many documents without connecting them to a decision the court can make. If an issue is no longer disputed, confirm that in writing and do not spend trial time proving it unnecessarily.
Make discovery and admissibility decisions before trial
Trial preparation is also a review of what is still missing. Compare the proof plan with disclosures, discovery responses, deposition testimony, subpoenas, and prior stipulations. Mark each item as ready, incomplete, disputed, or unnecessary. If a bank statement supports a property tracing argument, identify the account, date range, and witness who can explain it. If a text exchange is important, preserve the surrounding messages and information needed to show who sent it and when.
Separate three questions: whether a fact is relevant, whether the evidence can be admitted, and how much weight the judge may give it. A document can be relevant but still require authentication or a hearsay exception. A witness can have personal knowledge but still be limited by a prior order or an incomplete record. Raise known problems early enough for counsel to research them and for the court to address them efficiently. This review often narrows the exhibit list and makes the presentation clearer.
2. Build a usable evidence file
Organize documents by issue and date. Keep the original electronic file when metadata, messages, photographs, or spreadsheets may matter, and keep an accurate copy of anything filed or exchanged. A useful index identifies the exhibit number, date, description, issue, source, and sponsoring witness.
Evidence still must satisfy the rules of evidence and any case-specific order. California Evidence Code section 350 generally limits evidence to matters relevant to a disputed issue, while section 352 permits exclusion when the probative value is substantially outweighed by specified risks such as undue consumption of time or undue prejudice. Relevance alone does not guarantee admission. Authentication, hearsay, privilege, foundation, completeness, and timely exchange may also matter.
Do not alter a message, crop a photograph in a misleading way, or rely on a summary when the underlying record may be requested. For financial issues, reconcile statements and calculations to source records. For custody issues, organize records around the child’s needs and the requested parenting plan rather than accusations that do not prove a legal point.
3. Follow the court’s deadlines and local instructions
Create one calendar for every deadline in the case file, including trial briefs, exhibit and witness exchanges, subpoenas, discovery, motions in limine, expert disclosures, and proposed orders. The applicable deadline may come from a California Rule of Court, a local rule, a standing order, a department policy, or the judge’s minute order. The order in your case controls when it is more specific.
Do not assume that a procedure used in San Francisco, Santa Clara, Alameda, San Mateo, Contra Costa, Marin, Sonoma, or Napa County applies in another county—or even in every department of the same court. Check the applicable Superior Court website and the latest order for the assigned department. Ask counsel what must be filed, served, lodged, exchanged, or brought to court. A missed exchange deadline can create an evidentiary problem that preparation alone cannot fix.
4. Prepare witnesses and testimony
Make a witness chart stating what each witness personally knows, which issue the testimony supports, and what limits or credibility problems may be raised. A witness should understand the courtroom process without being coached to change facts. Practice listening to the question, answering only what is asked, pausing before answering, and saying “I do not know” or “I do not remember” when that is accurate.
Direct examination is questioning by the party who called the witness. Cross-examination is questioning by the opposing party. Testimony should be truthful, precise, and based on personal knowledge. Do not use the witness stand to argue with the other party, guess at motives, or read an unapproved script. If an interpreter, accommodation, expert, or child-related professional may be involved, address the arrangement early.
5. Understand the trial sequence
Depending on the judge and case, trial may include appearances and housekeeping matters, opening statements, testimony and exhibits, objections, cross-examination, redirect, and closing argument. The court may rule immediately or take the matter under submission. Family Code section 217 generally addresses live testimony and cross-examination in family-law hearings, subject to its exceptions and the court’s management of the proceeding. A trial date does not guarantee that every planned witness or exhibit will be used.
Prepare a concise opening outline, a witness order, exhibit list, question outline, objections to anticipate, and a closing checklist. If you represent yourself, learn the department’s rules for submitting exhibits and proposed orders; court staff cannot give individualized legal advice. If you have counsel, ask who will make each decision at trial and how you will communicate during breaks.
6. Prepare calculations and requested orders
For support, bring the records and assumptions supporting income, deductions, timeshare, health insurance, childcare, and other requested inputs. For property, identify characterization, tracing, valuation date, liabilities, and the proposed division. A spreadsheet is useful only if another person can follow its source documents and formulas.
Write the exact orders requested in plain language. Parenting requests should specify schedules, exchanges, holidays, communication, and decision-making terms where those details are disputed. Avoid asking for relief that is outside the pleadings or that the court has not set for trial without first obtaining legal advice.
7. Conduct a final readiness review
Before trial, confirm:
- The issues actually set for trial and the burden for each issue.
- Every filing, service, exchange, and subpoena deadline.
- Exhibit numbering, copies, electronic format, and authentication witnesses.
- Witness availability, remote appearance instructions, interpreters, and accommodations.
- Updated calculations and a proposed order.
- A realistic settlement position and authority to resolve issues.
- Transportation, technology, courtroom arrival, and a plan for confidential material.
Settlement remains possible before and during trial. A thoughtful settlement evaluation is not a sign that preparation failed; it is part of understanding risk, cost, time, and the relief a judge can realistically order.
What if new evidence appears shortly before trial?
Preserve the original, identify when and how it was obtained, and do not assume it can be used immediately. Tell counsel promptly or ask the court about the proper procedure. The response may involve a motion, supplemental exchange, stipulation, continuance request, or an objection. Do not conceal unfavorable information or attempt to solve admissibility for the first time while a witness is testifying.
