Checklist of Divorce Documents Needed in California

A family law attorney in San Mateo can help you complete this form accurately and gather all the necessary documentation for your case.

Mandatory Divorce Documents for California and San Mateo County
When filing for divorce in San Mateo, CA, the Superior Court requires a combination of statewide and county-specific documents to begin the legal process. All forms must be completed in black ink and printed on single-sided paper.
Key Divorce Documents in California include:
- FL-100 (Petition for Dissolution) and FL-110 (Summons), both of which are filed on day one.
- If children are involved, you must also complete FL-105/GC-120 (Child Custody Jurisdiction).
- Within 60 days of opening the case, both parties are required to file FL-150 (Income and Expense Declaration) and FL-142 (Schedule of Assets and Debts) to comply with state-mandated Financial Disclosure for Divorce in CA.
- In more complex or high-net-worth divorces, you may also need FL-160 (Property Declaration) to provide detailed information about the community and separate assets.
- Additionally, San Mateo County requires ADR-FM-101, the local Family Law Cover Sheet, to be submitted with your initial packet.
For convenience, the court offers “Family Law Common Form Packets” for download at sanmateo.courts.ca.gov, helping you stay organized and file correctly from the start.
Special Considerations for High-Conflict or High-Asset Divorce
In a high-conflict divorce, facts are often disputed. You’ll need more than basic documents:
- Forensic accounting reports are used to trace hidden money and verify income.
- Business appraisals are required if either spouse owns a company.
- Emails, texts, and social media posts related to threats or misconduct.
- Restraining orders or police reports for domestic violence cases.
Handling a complex divorce in San Mateo County requires guidance from a nearby family law attorney who knows how to present this evidence effectively in court.
Community Property Rules and Financial Disclosure for Divorce in CA
Under California law, most assets and debts acquired during a marriage are considered community property, meaning they are generally divided equally unless proven to be separate. As part of the required Financial Disclosure for Divorce in CA, each party must complete and exchange two key forms: the FL-142 (Schedule of Assets and Debts) and the FL-150 (Income and Expense Declaration). These forms must be served to your spouse within 60 days of filing for divorce. Final disclosures can only be waived if both parties agree in writing and attach a signed waiver.
Failing to provide complete and accurate financial information may result in court penalties, attorney fees, or even an overturned judgment. A knowledgeable divorce attorney in San Mateo can guide you through these disclosures to avoid errors and protect your legal and financial standing.
Step-by-Step Guide to Filing for Divorce in San Mateo
Filing for divorce requires careful attention to legal procedures and documentation. Here’s a general overview of the steps to help you stay on track and avoid delays, whether you’re working with a divorce attorney nearby or preparing independently:
1. Confirm Residency
Before you file, at least one spouse must meet the residency requirements of your state and county. In California, for example, one spouse must have lived in the state for at least six months and in the county for at least three months.
2. Complete the Required Forms
Start by filling out the petition for dissolution (FL-100), summons (FL-110), and any other required forms, such as a local court cover sheet or child custody forms if children are involved. If you’ve already gathered your Divorce Checklist documents, keep them organized for submission or review.
3. Make Copies of All Documents
Prepare at least two copies of each completed form. One will be filed with the court, one is for your records, and one must be served on your spouse.
4. File the Divorce Papers
Take the original forms and copies to your local courthouse and file them with the clerk. You will need to pay a filing fee unless you qualify for and request a fee waiver.
5. Serve the Divorce Papers
Your spouse must be formally served with the divorce documents. This can be done by a process server, a law enforcement officer, or a third party who is over 18 and not involved in the case. The server must then complete a Proof of Service form and file it with the court.
6. Exchange Preliminary Disclosures
Both parties are legally required to exchange financial information early in the process. This includes completing the Income and Expense Declaration (FL-150) and the Schedule of Assets and Debts (FL-142). These steps are important for Financial Disclosure in Divorce and must typically be completed within 60 days of filing.
7. Negotiate or Prepare for Trial
After disclosures are exchanged, the next phase involves reaching a settlement or proceeding to trial. Couples may negotiate directly, through attorneys, or in mediation. If an agreement cannot be reached, the court will schedule a hearing or trial.
8. Submit Final Judgment Paperwork
To finalize the divorce, submit the Judgment (FL-180) along with any supporting forms, such as child support or custody orders, and the Notice of Entry of Judgment. Once processed, the court will issue the final decree of dissolution.
Detailed directions are on the court’s self-help page (sanmateo.courts.ca.gov) and in “How to File for Divorce in San Mateo County” (onlinedivorcecalifornia.com).
Child-Related Records to Include in Your San Mateo Divorce Checklist
If your divorce involves children, the court’s priority will always be the child’s best interests. To support custody discussions and parenting arrangements, be sure to include the following records in your
Divorce Checklist in San Mateo:
- School calendars and recent report cards
- Copies of medical and dental insurance cards
- Childcare invoices and payment records
- Extracurricular activity schedules and tuition bills
- A proposed written parenting plan outlining custody and visitation
These documents help your divorce attorney, San Mateo, present a well-organized custody case and keep the conversation focused on what matters most – your children’s well-being. Including them early in the process can streamline the court’s review and strengthen your position in a San Mateo County divorce with children.
Avoid These Filing Errors in Your San Mateo Divorce Case
Even well-prepared clients can make small but costly mistakes during the San Mateo County Divorce Process. These errors can delay your filing, cause confusion during settlement talks, or lead the court to reject your documentation. Here are the most frequent document-related issues and how to avoid them:
1. Using Joint Bank Statements That Hide Transfers
One common mistake is submitting bank statements that only show summary information or combined balances. This can be a problem during Financial Disclosure for Divorce in CA, as important financial activities like large transfers, hidden deposits, or cash withdrawals can go unnoticed. To fix this, request full, itemized PDF statements directly from your bank’s online system. Be sure to include all pages, even those that appear blank, to confirm the integrity of the records.
2. Submitting Photocopies of Property Deeds
Many clients make the error of relying on scanned or photocopied versions of real estate ownership documents. Courts in California may reject these copies because they lack legal verification. Instead, order certified copies from the San Mateo County Recorder’s Office (or the county where the property is located). Certified deeds carry legal weight and help establish ownership details clearly in your Divorce Documents in California.
3. Ignoring Separate-Property Evidence
Another major oversight is failing to prove that gifts, inheritances, or pre-marital assets are separate from community property. Under California law, everything acquired during the marriage is presumed to be shared unless proven otherwise. You can fix this by including date-stamped documents such as gift letters, wills, or inheritance statements. If you purchased property or saved money before marriage, submit contracts or bank records showing sole ownership.
4. Skipping an Asset Spreadsheet
Not preparing a basic list of assets and liabilities can seriously slow down your case. Your divorce attorney nearby will need this inventory to complete forms like FL-142 or FL-160. Without it, negotiation becomes unclear and filings get delayed. Create a simple spreadsheet that includes each asset’s description, who owns it (you, your spouse, or both), and its estimated value. This helps with fast and accurate reporting during the San Mateo County Divorce Process.
5. Missing Signatures on the FL-150 Form
It’s surprisingly common for people to turn in unsigned FL-150 Income and Expense Declarations. The court will not accept forms that aren’t signed and dated; this results in processing delays and sometimes requires re-filing. Make sure to carefully sign and date every single page, even if the page includes only totals or blank sections.
