What this form asks for

The AI fills all of it, from your answers or your documents.

Form FL-170 is a Judicial Council of California family law declaration used by a petitioner (and in some situations both parties) to prove up the facts needed for the court to enter a default or uncontested judgment for dissolution or legal separation. It addresses key issues such as disclosure requirements (FL-140/FL-141/FL-144), property and debt division (often referencing FL-160 and the proposed judgment FL-180), and—if applicable—custody, child support, spousal/partner support, parentage, and attorney’s fees. The form is important because it provides the court with sworn statements required under Family Code section 2336 to grant judgment without a hearing in many cases. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

16 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Ensures exactly one 'Declaration Type' is selected (Dissolution vs. Legal Separation)

Validate that the filer selects either 'Dissolution' or 'Legal Separation' and not both or neither. These are mutually exclusive proceedings and drive which statements (e.g., dissolution residency requirement vs. legal separation advisement) apply. If validation fails, block submission and prompt the user to choose exactly one declaration type.

Ensures exactly one 'Type of Case' is selected (Uncontested / Default with agreement / Default without agreement)

Check that exactly one of the three case-type checkboxes is marked. The form’s logic and required supporting documents differ depending on whether the matter is uncontested or default (with/without agreement). If multiple or none are selected, the submission should be rejected because the court cannot determine the correct procedural track.

Validates 'Information Source Declaration' selection (Petition/Response/Amended) is complete and consistent with case type

Require at least one of 'Petition', 'Response', or 'Amended' to be selected to identify what filing the declarant is attesting is true and correct. If the case type indicates no response has been filed (default scenarios), flag an error if 'Response' is selected without an explanation/attachment indicating why response information is being used. On failure, require correction or an attachment clarifying the source.

Validates Declaration of Disclosure option selection (5a/5b/5c/5d) is present and mutually exclusive

Ensure the filer selects one—and only one—disclosure pathway (both filed, default with proof of service, default by publication/posting, or mutual waiver in uncontested action). These options represent different legal prerequisites and waivers and should not be combined. If validation fails, prevent filing and require the user to select the single applicable disclosure scenario.

Requires supporting proof/waiver attachments based on the selected disclosure pathway

If 5a is selected, require confirmation that FL-141 and FL-150 are filed or being filed concurrently (and optionally capture filing dates/receipt IDs if your system supports it). If 5d (mutual waiver) is selected, require FL-144 or a settlement agreement/proposed judgment containing the executed waiver provision; if 5b is selected, require proof of service for preliminary FL-140; if 5c is selected, require indication of court-ordered publication/posting service. If the required supporting document is missing, mark the submission incomplete and block acceptance.

Validates Assets/Debts disposition selection and enforces mutual exclusivity

Check that the filer selects either 'No assets or debts to be disposed of' or 'Assets and debts listed in FL-160'—not both. These statements are logically inconsistent and affect whether a Property Declaration (FL-160) must be provided. If both or neither are selected, reject submission and prompt the filer to correct the assets/debts section.

And 10 more checks
  • Requires FL-160 Property Declaration when assets/debts are listed for division
  • Validates child-related sections are complete when custody/visitation or child support orders are requested
  • UCCJEA (FL-105) change status validation and updated form requirement
  • Validates 'Existing custody order in another case' details when selected
  • Validates 'Child support enforced in another case' details when selected
  • Earning ability request requires party selection and supporting facts/attachment
  • Public assistance status must be singular and triggers LCSA routing requirements
  • Spousal/partner support selections are mutually exclusive and require supporting basis when ordered
  • Attorney/party contact and attorney credential format validation (email/phone/fax/State Bar number)
  • Signature block completeness: declarant name, date, and signature presence

How to Fill Out FL-170 Online for Free in 2026

What the AI walks you through.

  1. Go to Instafill.ai and upload the FL-170 PDF (or select “FL-170” from the form library).
  2. Enter case and court details (county, branch, addresses), and party information (petitioner, respondent, case number, attorney/party contact details).
  3. Choose the case posture and type (default/uncontested; default with or without agreement) and confirm you are not requesting relief beyond the petition.
  4. Complete the disclosure section by selecting the correct disclosure/waiver option (e.g., FL-141/FL-150 filed; waiver due to publication; waiver of final disclosures; or mutual waiver with FL-144).
  5. Provide property/debt statements (no assets/debts or reference the FL-160 Property Declaration) and confirm the proposed division in the FL-180 Judgment is fair/equitable.
  6. If applicable, complete children/support sections (UCCJEA FL-105 status, custody/visitation, child support details, public assistance, spousal/partner support requests/waivers, parentage, and attorney fees—referencing FL-150, FL-157, FL-319 as needed).
  7. Review the AI validation checks, generate any needed attachments, then finalize by entering the date, printing/creating an e-signature-ready version, and saving for filing with the court along with the proposed FL-180 and supporting forms.

Common Mistakes in Completing FL-170

The ones the AI is built to catch.

Checking the wrong “Type of case” (Uncontested vs. Default with/without agreement)
People often confuse “uncontested” with “default,” or they select more than one option because the labels sound similar. Choosing the wrong type can cause the clerk/judge to reject the packet or require corrected filings because the required proofs, waivers, and attachments differ by case type. Before checking a box, confirm whether a Response was filed and whether there is a signed written agreement/stipulated judgment. AI-powered tools like Instafill.ai can help by prompting the correct selection based on your answers and flagging conflicting choices.
Inconsistent disclosure selections (FL-140/FL-141/FL-144) and missing required waivers
A very common error is checking a disclosure waiver box (e.g., mutual waiver in uncontested cases or waiver in default cases) without actually including the required supporting form/waiver language (such as FL-144 or the correct proof of service). This can delay judgment because the court needs a clear, legally valid disclosure path for the case type. Match item 5 (a/b/c/d) to what was actually served/filed and attach the referenced waiver/attachments when required. Instafill.ai can reduce this by validating that the correct companion forms are present and that the selected disclosure option is supported.
Claiming publication/posting service (default) without matching the court-ordered service history
Some petitioners check the publication/posting option (item 5c) even though service was personal/substituted, or they forget that publication/posting must be under court order. If the service method doesn’t match the record, the court may refuse to enter default judgment or require amended declarations. Verify the method of service used for the Summons and ensure the file contains the correct proof(s) and any court order authorizing publication/posting. Instafill.ai can help by asking service-method questions and warning when the selected option conflicts with typical required documents.
Not attaching FL-160 Property Declaration when assets/debts exist (or checking “no assets/debts” incorrectly)
People frequently check “There are no assets or debts” to simplify the process, even when there are bank accounts, vehicles, retirement plans, credit cards, or tax debts. If the court later sees inconsistencies (or the judgment omits property), it can create enforcement problems and may require reopening or additional filings. If there is anything to divide or confirm as separate/community, complete FL-160 with estimated values and ensure the proposed FL-180 matches it. Instafill.ai can help prevent this by prompting for common asset/debt categories and generating consistent entries across forms.
Proposed Judgment (FL-180) doesn’t match what’s checked on FL-170
A common rejection reason is internal inconsistency: FL-170 requests custody/support/property orders “as set forth in FL-180,” but FL-180 is missing those orders or states something different. This happens when people reuse old templates or update one form but not the other. Review each checked request (custody, child support, spousal support, fees, name restoration) and confirm FL-180 contains the corresponding terms. Instafill.ai can help by cross-checking fields across documents and flagging mismatches before filing.
Leaving the “facts that support the requested judgment” blank or too vague (especially in default cases)
Item 6 requires supporting facts, and in default matters the form specifically asks you to state your reasons. Many filers write “see petition” or leave it empty, which can lead the court to require an appearance or additional declarations. Provide concise, case-specific facts (service/default status, separation date context if relevant, and why requested orders are appropriate) and use attachments (6c/6d) when needed. Instafill.ai can help by generating a structured, court-appropriate narrative and ensuring the correct attachment box is checked when you add pages.
UCCJEA (FL-105) status checked incorrectly or not updated when circumstances changed
People often check “has not changed” without confirming whether addresses, custody cases, or the child’s residence history changed since the last FL-105. If the information is outdated, the court may delay custody orders or require an updated FL-105, especially when another case exists. Re-check the last filed FL-105 and update it if any child residence/case information changed, then attach the updated form as required. Instafill.ai can help by tracking prior entries and prompting updates when you indicate moves or new cases.
Missing county/case number details for “another case” (custody or child support enforcement)
When filers check boxes indicating another case exists (custody order elsewhere or child support enforcement), they frequently omit the county and case number. Without that information, the court cannot verify jurisdiction, coordinate orders, or understand enforcement status, which can stall processing. If you check any “another case” box, always fill in both the county and the case number exactly as shown on the other case’s documents. Instafill.ai can help by requiring these fields when the related checkbox is selected and formatting the case number consistently.
Contradictory spousal/partner support selections (waive vs. reserve vs. terminate vs. order)
Item 8 contains multiple options that are mutually exclusive in practice, and people sometimes check more than one (e.g., “give up forever” and “reserve jurisdiction”) or select an option without providing the required basis/attachment. Contradictions can cause the judge to reject the proposed judgment or require clarification because support rights can be permanently affected. Choose one clear outcome (waive, terminate, reserve, or order) and ensure the supporting basis is consistent (FL-157, attachment 8d, or written agreement). Instafill.ai can help by detecting conflicting selections and guiding you to a single consistent support outcome.
Requesting attorney fees without the required support (FL-150 and/or FL-319 facts)
Filers often check that attorney fees should be ordered but do not include the supporting Income and Expense Declaration (FL-150) or the factual basis attachment (FL-319) when needed. Courts typically require financial information and a clear explanation to make a fees order, so missing support can lead to denial or a request for additional documents. If you request fees, confirm a current FL-150 is on file (or attach a new one) and include FL-319 or a detailed declaration supporting the request. Instafill.ai can help by reminding you of required companion forms when you select the attorney-fees option.
Signature/date and identity fields incomplete or inconsistent (names, case number, party roles)
A frequent technical error is leaving the date blank, not printing/typing the declarant name, or using nicknames/abbreviations that don’t match the Petition/Response and caption. Even small inconsistencies (case number format, swapped petitioner/respondent names) can cause filing delays or confusion about who is making the declaration under penalty of perjury. Copy names and the case number exactly from the court’s caption and verify the declarant is the correct party for the selected case type. Instafill.ai can auto-populate captions consistently across forms and validate that required signature/date fields are completed.

FL-170 has a Form Complexity Index of 55 out of 100, in the moderate tier: 106 fillable fields across 3 pages. Instafill.ai's AI fills it in under a minute, with every field there for you to review before you download.
What is Form FL-170 used for?
Form FL-170 (Declaration for Default or Uncontested Dissolution or Legal Separation) is used to ask the court to enter a judgment in a divorce/dissolution or legal separation case without a trial. It provides sworn statements supporting the orders requested in the proposed Judgment (FL-180).
Who needs to fill out FL-170?
You typically complete FL-170 if your case is proceeding by default (the respondent did not file a response) or if the case is uncontested and you want the court to enter judgment based on paperwork. The petitioner commonly files it, but it depends on the posture of the case and local court requirements.
What’s the difference between “Uncontested,” “Default with agreement,” and “Default without agreement” on this form?
“Uncontested” generally means both parties have appeared and are submitting a written agreement for the court to approve. “Default with agreement” means no response was filed, but the parties have a written agreement and agree the case can proceed as a default. “Default without agreement” means no response was filed and there is no written agreement or stipulated judgment.
Do I have to complete the Declaration of Disclosure forms (FL-140/FL-141) to file FL-170?
In many cases, yes—FL-170 asks you to confirm what disclosure steps were completed or waived. You may need FL-141 (Declaration Regarding Service of Declaration of Disclosure) and often FL-150 (Income and Expense Declaration), and you must select the correct disclosure option (5a–5d) that matches your situation.
When can I check the box that says preliminary disclosure (FL-140) is not required due to service by publication or posting?
You can check that option when the case is proceeding by default, you are the petitioner, and the summons was served by publication or posting under a court order. In that situation, the form states preliminary disclosure is not required and you may waive receipt of the respondent’s final disclosure.
What does it mean to “waive receipt of the final Declaration of Disclosure (FL-140)”?
It means you are giving up the right to receive the other party’s final financial disclosure before judgment. Waivers can have important consequences, so make sure the waiver option you select matches your case type (default vs. uncontested) and any required waiver document (such as FL-144) is included when applicable.
What should I do about property and debts—do I need FL-160?
If there are no assets or debts for the court to divide, you can check the “no assets or debts” statement. If there are community or quasi-community assets/debts, you generally list them on a Property Declaration (FL-160) and indicate that the proposed division in the Judgment (FL-180) is fair and equal (or fair/equitable if there is a negative estate).
How do I complete the child custody and visitation section if we already have a schedule?
You can state the current custody/visitation (parenting time) schedule that is already ordered or currently being followed, or attach it as an attachment if needed. FL-170 also allows you to request that custody and visitation be ordered as set forth in the proposed Judgment (FL-180).
What is the UCCJEA form (FL-105), and what does it mean if it “has changed”?
FL-105 is the Declaration Under the Uniform Child Custody Jurisdiction and Enforcement Act, which provides information about the children’s addresses and custody cases. On FL-170 you indicate whether that information has changed since it was last filed; if it has changed, you typically need to file an updated FL-105.
How does FL-170 handle child support, including cases enforced in another county?
FL-170 lets you request child support as set forth in the proposed Judgment (FL-180) and confirm the attached child support calculation is correct. If child support is being enforced in another case, you can list the county and case number, and you can also request support based on a party’s earning ability if appropriate facts are provided.
Do I need to file an Income and Expense Declaration (FL-150) with FL-170?
If you are requesting spousal/partner support, family support, or attorney’s fees, the form indicates you should submit a completed FL-150 unless a current one is already on file. You should also include your best estimate of the other party’s income.
What does it mean to permanently waive or terminate spousal/partner support on FL-170?
Checking the waiver/termination options means you are asking the court to end support rights forever (either giving up your right to receive support or asking to terminate the other party’s right). If you are unsure, consider the “reserve jurisdiction” option, which asks the court to keep the ability to address support later.
What is a “status-only judgment,” and when would I check that box?
A status-only judgment ends marital or domestic partner status while reserving other issues (like property, support, or custody) for later. You would check it only if you are specifically requesting termination of status now and want the court to decide remaining issues later.
Can AI help me fill out Form FL-170 accurately?
