The first weeks of divorce can feel oddly administrative. You gather account statements, read court forms after work, and decide whether a conversation with your spouse counts as an agreement. For California families, this may happen while juggling school schedules, highway commutes, and a mortgage stretching the household budget. Common divorce mistakes at this stage are often ordinary: missed deadlines, incomplete disclosures, rushed agreements, and decisions made before the legal consequences are clear.
A California divorce follows a sequence: start the case, properly notify the other spouse, exchange financial information, resolve property, support, and parenting issues, and submit the judgment paperwork. Getting these steps right early can prevent delays and protect your options.
Before You File, Know What the Process Requires
A California divorce generally begins with a Petition (FL-100) and Summons (FL-110). For most married couples, either spouse must have lived in California for at least six months and in the filing county for at least three months. After filing, the papers must be properly served, and the respondent generally has 30 days after service to respond.
Filing does not finish the divorce. California also has a minimum waiting period before marital status can end, but the passage of six months does not automatically finalize a divorce. The parties still need to complete the required steps—financial disclosures and decisions about property and debt, spousal support, and, when applicable, custody and child support. Those issues may be resolved by agreement or by a judge before the case reaches final judgment.
That sounds orderly on paper. Problems often begin when someone treats one step as separate from the next.
What Common Mistakes Do Spouses Make When Filing for Divorce in California?
In our experience helping clients navigate divorce in California, we see several mistakes over and over again.
Mistake 1: Filing Before You Know What Needs Immediate Attention
Starting the case without identifying urgent issues can leave you reacting instead of planning. The petition asks what you want the court to decide, and some problems cannot wait until judgment is entered.
You may need temporary orders regarding where the children will live, who will pay certain bills, or whether temporary support is appropriate. Safety concerns may require a different or additional request. California’s divorce process allows parties to request temporary orders while the case is pending rather than waiting for final judgment.
The fix: Before filing, identify what must be stable during the next 30 to 90 days. Separate immediate needs from final divorce terms, then gather the facts and documents that support any temporary request.
Mistake 2: Treating Service and Deadlines Like Clerical Details
One of the most preventable divorce mistakes to avoid is assuming filing means your spouse has been legally notified. It does not.
In a standard divorce, you cannot personally serve your spouse. Service must follow California’s rules, and proof of service must be completed. Once served, the respondent generally has 30 days to respond.
Court notices can create additional deadlines. Missing a deadline can do more than delay the case. A respondent who does not file a response on time may face default, allowing the case to proceed without their input.
The fix: Keep one calendar for filings, service dates, hearings, disclosures, and court-ordered tasks. Save stamped copies and proofs of service together. Read every court notice as soon as it arrives.
Mistake 3: Making Major Moves After Automatic Orders Take Effect
The summons is not just a cover sheet. California family law summonses may include automatic temporary restraining orders that limit certain actions while the case is pending.
The standard orders generally restrict transferring or concealing property outside the ordinary course of business or necessities of life, changing certain insurance coverage or beneficiaries, and taking the parties’ minor children out of California without written consent or a court order.
This is where well-intentioned choices can create trouble. Moving money to keep it safe, canceling insurance, or transferring an asset to a relative may violate the automatic orders already in effect.
The fix: Read the summons before major financial, insurance, or travel decisions. If something needs to change, determine whether written consent or a court order is required.
Mistake 4: Treating Financial Disclosures as Routine Paperwork
California requires meaningful financial transparency in divorce. Preliminary disclosures identify assets, debts, income, and expenses, even when a spouse believes an item is separate property. The petitioner generally must serve preliminary disclosures within 60 days after filing the petition, and a respondent who files a response generally has 60 days after filing that Response to serve preliminary disclosures.
The duty to disclose material financial information continues as the case develops. Failure to comply can lead to monetary sanctions, attorney fees, or challenges to a judgment.
People may miss not only secret accounts but also old retirement plans, stock awards, business interests, tax liabilities, cryptocurrency holdings, reimbursement claims, or debts in one spouse’s name.
The fix: Treat disclosure as an inventory rather than a formality. Gather tax returns, pay records, account statements, retirement documents, real estate records, business information, and major debt records. If something is missing or unclear, address it before relying on the disclosure.
Mistake 5: Agreeing Before You Know What the Numbers Mean
Wanting the divorce to be finished quickly is understandable, but speed and efficiency are not the same.
A settlement can look balanced on paper while producing very different real-world results. A retirement account, cash account, business interest, and home equity may have the same stated value but different tax consequences, liquidity, or future costs.
The fix: Do not negotiate from account balances alone. Confirm what exists, how it is characterized, what it is worth, and what obligations come with it. Businesses, substantial equity compensation, retirement benefits, and complex tax issues are strong reasons to get legal and, when appropriate, financial advice before finalizing terms.

Mistake 6: Turning Social Media into Unnecessary Evidence
A frustrated post, vacation photo, dating profile, or comment about money can be copied, forwarded, or used later if it conflicts with a position you take in negotiations or court.
Deleting everything is not always the answer. If you think a post, message, or account could matter to the case, ask your lawyer before removing it. The safer approach is to stop creating avoidable problems.
The fix: Assume anything you post could be read by your spouse, the other lawyer, or the judge. Do not discuss the case, attack the other parent, post spending that contradicts financial claims, or use children as messengers online. Privacy settings are not the same as privacy.
Among the simplest mistakes to avoid during divorce is treating a private account as a private conversation.
Mistake 7: Assuming Court Forms Can Spot Legal or Financial Risk
California’s self-help materials are useful, and some straightforward divorces can be completed without full representation. However, forms do not tell you whether a proposed settlement is financially sound, whether an asset has a community component, what evidence supports a custody request, or whether a support position accounts for all relevant income.
Complexity can hide behind a simple filing. A case may involve a house purchased before marriage but paid down during it, a retirement account with pre-marriage contributions, a closely held business, or a parenting dispute that becomes serious after filing.
The fix: Match the level of legal help to the stakes. Full representation may make sense in a contested case, while a more limited consultation or agreement review may be enough when the issues are narrower.
San Mateo County Filers Should Check the Local Requirements Too
California Judicial Council forms are only part of the filing picture. San Mateo County also uses local family law forms and rules. For example, its local form packet includes the Notice of ADR Options (FL-2), and local rules supplement statewide procedure. Checking the county requirements before filing can prevent avoidable corrections after the case starts.

Frequently Asked Questions
Can My Spouse Refuse to Let Me Get Divorced in California?
No. One spouse does not need the other spouse’s agreement to seek a California divorce. If a properly served respondent does not respond within the applicable time, the petitioner may eventually ask the court to proceed through the default process. A default does not automatically finalize the divorce; the petitioner must still complete the required disclosures and submit the judgment paperwork for court approval.
Can Spouses File for Divorce Together in California?
Yes. Beginning January 1, 2026, California allows spouses or domestic partners who agree on all issues to start a divorce or legal separation together using a joint petition. If they cannot agree on everything, or if one person revokes the joint petition, the case proceeds through the regular divorce process.
A joint filing can simplify the start of an agreed case, but it does not eliminate financial disclosure requirements or the need for a final judgment.
What If I Cannot Afford the California Divorce Filing Fee?
You may ask the court for a fee waiver if you cannot afford the filing fee. Eligibility can be based on receiving qualifying public benefits, having a household income below the applicable limit, or being unable to pay court fees while meeting basic household needs.
A fee waiver addresses court costs. It does not change the requirements for service, disclosures, resolving issues, or obtaining a judgment.
Should I Change My Will or Beneficiaries As Soon As I File?
Review them, but do not make changes blindly. Divorce can affect rights under wills, trusts, retirement plans, joint-tenancy arrangements, and other transfers. At the same time, the family law Summons restricts certain beneficiary and insurance changes while the case is pending.
Before changing estate-planning documents, insurance beneficiaries, retirement designations, or transfer-on-death accounts, confirm what the automatic orders permit and whether consent or a court order is required.
