What this form asks for

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

Form FL-170 (Declaration for Default or Uncontested Dissolution or Legal Separation) is a sworn declaration filed in California family law cases when the matter is proceeding by default or is uncontested. It tells the court the case posture (default/uncontested), confirms required disclosures and waivers (e.g., FL-140/FL-141/FL-144), and supports the orders requested in the proposed Judgment (FL-180), including property division, custody/visitation, child support, and spousal/partner support where applicable. It is important because it provides the factual basis the court relies on to enter judgment without a hearing unless the court orders an appearance. 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 proceeding type is selected (Dissolution vs. Legal Separation)

Validate that the filer selects either DISSOLUTION or LEGAL SEPARATION, but not both and not neither. This is critical because different statutory statements and eligibility requirements apply depending on the proceeding type. If validation fails, block submission and prompt the user to choose exactly one proceeding type.

Validates required court and case identification fields are complete

Check that the Superior Court county, branch name (if provided on the form), court street address or mailing address, and the case number are present. These fields are required to route the filing to the correct court location and match it to the correct case. If missing or incomplete, the submission should be rejected with a message identifying which court/case fields must be completed.

Validates petitioner and respondent names are present and not identical

Ensure both PETITIONER and RESPONDENT names are provided and that they are not the same string (after trimming and normalizing case/spacing). This prevents misidentification of parties and downstream errors in judgment preparation and service records. If validation fails, require correction before acceptance.

Validates contact information formats (email, phone, fax) when provided

If an email address is entered, validate it matches a standard email format; if telephone/fax numbers are entered, validate they contain a valid number of digits (e.g., 10 digits for US numbers) and allowable punctuation. Correct formatting is important for court and party communications and to avoid undeliverable notices. If invalid, flag the specific field and require a corrected format or allow the user to clear the optional field.

Validates address fields are internally consistent (city/state/ZIP)

When a street address is provided, require city, state, and ZIP code to also be present, and validate state is a 2-letter code and ZIP is 5 digits (or 5+4). This ensures proper service and correspondence and reduces returned mail. If validation fails, prompt for missing components or corrected state/ZIP formatting.

Validates attorney section consistency (attorney vs. self-represented)

If an attorney name or firm name is provided, require a State Bar Number and attorney contact details; if the filer is self-represented, ensure attorney-only fields are blank or clearly marked as not applicable. This prevents filings from being treated as represented without required bar information. If validation fails, require either completion of attorney credentials or removal of attorney indicators.

And 10 more checks
  • Ensures exactly one 'Type of case' option is selected and matches required sub-statements
  • Validates default-by-publication/posting logic and disclosure waiver consistency
  • Validates Declaration of Disclosure pathway selection and required companion forms/attachments

  • Validates child-related sections are complete when minor children or custody/support orders are requested
  • Validates 'other case' references include both county and case number when checked
  • Validates public assistance selections and payee direction are consistent
  • Validates spousal/partner support elections are mutually exclusive and complete

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), party information (petitioner/respondent), and the case number exactly as shown on your court documents.
  3. Use the guided prompts to choose the correct case type and posture (default without agreement, default with agreement, or uncontested) and confirm you are not requesting relief beyond the petition.
  4. Complete the disclosure section by indicating which declarations were served/filed (e.g., FL-141, FL-150) and whether preliminary/final declarations of disclosure (FL-140) are waived or required, including any related stipulation (e.g., FL-144).
  5. Fill in the requested orders and supporting facts (property/debts and references to FL-160 and FL-180; custody/visitation and UCCJEA FL-105; child support details; spousal/partner support selections; attorney fees if requested).
  6. Review Instafill.ai’s validation checks for missing attachments, inconsistent selections, and required signatures/penalty-of-perjury language; then generate a clean, court-ready PDF.
  7. Download, sign/date where required, attach referenced forms/attachments, and file/serve the completed FL-170 according to your county’s court rules (e-filing or in person).

Common Mistakes in Completing FL-170

The ones the AI is built to catch.

Checking the wrong case type (Uncontested vs. Default with/without agreement)
People often misunderstand the difference between an uncontested case (both parties appeared) and a default case (no response filed), or they check multiple boxes when the form requires only one. This can cause the clerk/judge to reject the packet or require a corrected FL-170 because the requested procedure and required attachments differ by case type. Avoid this by confirming whether a Response was filed and whether there is a signed written agreement, then check only the single box that matches your situation; AI-powered tools like Instafill.ai can flag conflicting selections before you file.
Requesting relief not asked for in the Petition
In default matters, filers sometimes ask for new orders in FL-170/FL-180 (support, property division terms, fees, custody provisions) that were not requested in the original Petition. Courts generally will not grant default relief beyond what was noticed in the Petition, which can lead to denial of the proposed judgment or a requirement to amend and re-serve. To avoid this, cross-check every order in the proposed Judgment (FL-180) against the Petition’s requests; Instafill.ai can help compare entries and warn when a requested order exceeds what was pled.
Incorrect or incomplete disclosure/waiver section (FL-140/FL-141/FL-144)
A very common error is selecting a disclosure option (items 5a–5d) that doesn’t match the case facts—especially confusing default by publication/posting, default with proof of service of preliminary disclosures, and uncontested mutual waiver. Missing the required companion forms (FL-141, FL-144, or proof of service) can stop the judgment from being entered. Avoid this by verifying which disclosure documents were served, whether service was by publication/posting, and whether a mutual waiver was properly executed under penalty of perjury; Instafill.ai can validate that the correct supporting forms are included for the option you select.
Leaving the “facts that support the requested judgment” too vague or blank
Filers often write nothing or provide a generic statement, especially in default cases where the form explicitly asks for reasons supporting the judgment. If the court cannot see a factual basis for the requested orders (property division, support, custody), it may require an appearance, request additional declarations, or reject the submission. Provide concise, case-specific facts (dates, service method, agreement status, and why requested orders are appropriate) and reference attachments when used; Instafill.ai can prompt for the minimum factual details typically expected for each scenario.
Property section mismatch: claiming “no assets/debts” while also referencing FL-160 or dividing property
People frequently check the box stating there are no assets or debts, but elsewhere submit or reference a Property Declaration (FL-160) or propose a division in FL-180. This inconsistency raises red flags and can delay entry of judgment because the court cannot tell whether property orders are needed. Avoid this by choosing one consistent approach: either truly no community/quasi-community property/debt, or complete FL-160 with values and a clear proposed division; Instafill.ai can detect contradictory property selections and require a consistent set of answers.
Missing or outdated Income and Expense Declaration (FL-150) when requesting support or fees
Support and attorney-fee requests often require a current FL-150, but filers sometimes rely on an old one on file or forget to attach it while still asking for spousal support, family support, or fees. The court may deny or postpone support/fee orders without current financial information, leading to re-filing and delays. Avoid this by filing an updated FL-150 whenever finances have changed or when the court requires a current declaration, and include your best estimate of the other party’s income as instructed; Instafill.ai can remind you when FL-150 is required based on the boxes you check.
Contradictory spousal/partner support selections (waive vs. reserve vs. order)
Item 8 contains multiple mutually exclusive options, and people often check more than one (e.g., “I give up forever” and “reserve jurisdiction”) or select termination for the wrong party. Conflicting support selections can invalidate the requested order or force the court to request clarification because the judgment must be unambiguous. Avoid this by deciding the single intended outcome (waive forever, terminate for one party, reserve jurisdiction, or order support) and ensuring it matches any written agreement and FL-180; Instafill.ai can enforce mutually exclusive logic so incompatible boxes can’t be selected together.
Child custody/UCCJEA (FL-105) and existing orders not properly disclosed
When minor children are involved, filers sometimes forget to confirm whether FL-105 is current, omit details about existing custody/visitation orders in another case, or leave county/case number blank. Missing or inconsistent jurisdiction information can cause the court to reject the packet or require additional filings to confirm California’s authority to make orders. Avoid this by ensuring FL-105 is complete and up to date, and by listing any other cases/orders with the correct county and case number; Instafill.ai can prompt for required jurisdiction fields when children are indicated.
Public assistance and local child support agency (LCSA) fields left incomplete
People often check that a party is receiving public assistance (or that child support is enforced elsewhere) but fail to complete the required follow-up details, such as the county, case number, or payee instructions involving the LCSA. This can lead to incorrect payee language in the judgment or delays while the court seeks clarification or agency sign-off. Avoid this by completing every dependent field when public assistance or enforcement is involved and ensuring the proposed judgment includes the correct payment routing; Instafill.ai can automatically require the related fields once you indicate public assistance/enforcement.
Caption and court information errors (county, branch, addresses, party names, case number)
A frequent technical mistake is entering the wrong county/branch, using mailing addresses where street addresses are required, misspelling party names, or using an incorrect/incomplete case number. Even small caption errors can cause filing rejection, misrouting to the wrong courthouse, or mismatches with the court’s case management system. Avoid this by copying the case number and court location exactly as shown on prior filed documents and using full legal names consistent across all forms; Instafill.ai can standardize and validate these fields across the entire packet.
Missing signature/date or signing in the wrong place (penalty of perjury)
Because FL-170 is a declaration under penalty of perjury, people sometimes forget to date it, type/print the name but don’t sign, or sign in a non-signature field. An unsigned or undated declaration is typically rejected and will delay judgment entry. Avoid this by confirming the declarant’s signature, printed name, and date are all present on the correct line before filing; if you’re working from a flat non-fillable PDF, Instafill.ai can convert it into a fillable version and ensure signature/date fields aren’t missed.

What is California 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 when the case is proceeding by default or is uncontested. It lets you provide sworn statements supporting the orders requested in your proposed Judgment (FL-180).
Who needs to fill out FL-170?
Typically, the petitioner (and sometimes a party in an uncontested matter) completes FL-170 when requesting a default judgment or submitting an uncontested judgment package. You sign under penalty of perjury that the statements are true and that the case can be decided based on the declaration.
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 there is a written agreement and the parties allow the case to 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 file a proposed Judgment (FL-180) with FL-170?
Yes—FL-170 repeatedly references that custody, support, property, fees, and other orders should be “as set forth in the proposed Judgment (FL-180).” In most default/uncontested judgment packets, FL-180 is a required companion form.
What disclosure forms are required with FL-170 (FL-140, FL-141, FL-144)?
Many cases require a Declaration of Disclosure (FL-140) and a Declaration Regarding Service of Declaration of Disclosure (FL-141). If both parties mutually waive final disclosures in an uncontested case, the waiver is usually documented on FL-144 (or included in the agreement/proposed judgment as stated on FL-170).
When is service of the preliminary Declaration of Disclosure (FL-140) NOT required?
FL-170 states that if the case is proceeding by default and the respondent was served by publication or posting under court order, service of the preliminary FL-140 is not required. In that situation, the petitioner can also waive receipt of the respondent’s final FL-140.
What if I already served the preliminary FL-140 in a default case—what do I check?
If you are the petitioner in a default case and you filed proof of service of the preliminary FL-140 with the court, FL-170 includes an option reflecting that. You can also indicate you waive receipt of the respondent’s final FL-140 (as the form provides).
How do I handle property and debts on FL-170 if we have none?
FL-170 includes a statement you can select indicating there are no assets or debts for the court to dispose of. If that is true, you generally do not need to propose a division on FL-160, but your FL-180 should still be consistent with that statement.
What if we do have community property or debts—what additional form is needed?
If there are community or quasi-community assets/debts, FL-170 points you to complete a current Property Declaration (FL-160) with estimated values and the proposed distribution to each party. The proposed division should match what you request in the Judgment (FL-180).
What sections do I complete if we have minor children (custody/visitation/child support)?
You’ll typically complete the custody/visitation and child support items that say orders should be “as set forth in the proposed Judgment (FL-180).” FL-170 also references the UCCJEA form (FL-105) and asks whether its information has changed since it was last filed.
Do I need to file an Income and Expense Declaration (FL-150) with FL-170?
Often yes—FL-170 states that both parties have filed (or are filing concurrently) FL-141 and FL-150, and it also notes FL-150 is required if support or attorney’s fees are requested unless a current one is already on file. You should include your best estimate of the other party’s income when support is at issue.
How do I request spousal/partner support (or waive it) on FL-170?
FL-170 lets you request spousal/partner support per FL-180, ask to terminate support forever, reserve jurisdiction to award support later, or permanently waive your right to receive support. If you need to explain the basis, the form references using FL-157, an attachment (Attachment 8d), or a written agreement.
Can I request attorney’s fees on this form, and what attachment is used?
Yes—FL-170 includes a section to request attorney’s fees as set forth in the proposed Judgment (FL-180). It references using Request for Attorney’s Fees and Costs Attachment (FL-319) to provide the supporting facts.
What does “status only judgment” mean on FL-170?
A status-only judgment asks the court to terminate marital or domestic partner status now, while reserving other issues (like property or support) for later determination. FL-170 includes a specific statement you can select if you are requesting status-only relief.
Can AI help me fill out FL-170, and how would I do it online if the PDF isn’t fillable?
Yes—AI tools can help reduce errors and save time by auto-filling fields from your case details; services like Instafill.ai use AI to accurately populate form fields. If your FL-170 PDF is flat/non-fillable, Instafill.ai can convert it into an interactive fillable form and then guide you to complete it online before you download, sign, and file it with the court according to your county’s submission rules.
