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

Attorney Information Completeness

Validates that all required fields for attorney information (State Bar Number, Name, Firm Name, Street Address, City, State, Zip Code, Telephone No., Fax No., E-mail Address) are completed. Incomplete attorney information can lead to miscommunication or inability to contact the legal representative.

Party Name Format and Completeness

Ensures that the Petitioner and Respondent names are provided in a full, legal format (First, Middle Initial, Last Name) and are not abbreviated. This is crucial for accurate case identification and legal proceedings.

Child Information Completeness

Verifies that for each child listed, the Full Name and Date of Birth are provided. Missing or incorrect child information can lead to errors in legal orders concerning custody, support, and parentage.

Child Birthdate Format

Checks that the birthdate for each child is entered in a valid date format (e.g., MM/DD/YYYY). Incorrect date formats can cause issues with age calculations and legal record-keeping.

Petitioner's Role Validation

Ensures that at least one of the options in Item 1 (Petitioner's role) is selected. This clarifies the petitioner's standing and basis for filing the petition, preventing incomplete or ambiguous filings.

Jurisdiction Basis Selection

Validates that at least one basis for court jurisdiction over the respondent (Item 3a or 3b) is selected. Without a valid jurisdictional basis, the court cannot proceed with the case.

Common Mistakes in Completing FL-200

The ones the AI is built to catch.

Incomplete or Incorrect Party Information
Failing to provide full legal names, correct addresses, or contact details for the Petitioner, Respondent, or other parties involved. This can lead to delays in service, miscommunication, and procedural errors. Always double-check that all names are spelled correctly and that addresses and phone numbers are current and accurate. AI-powered form filling tools can help by auto-populating known information and flagging missing fields.
Missing or Incorrect Case Number
Omitting the case number or entering it incorrectly is a frequent error. This prevents the court from properly associating the document with the correct legal proceeding, potentially causing it to be rejected or misfiled. Ensure the case number is copied exactly as it appears on previous court documents. AI tools can help by remembering and accurately inserting case numbers for recurring filings.
Failure to Specify Reasons or Details
Many fields require specific explanations or reasons (e.g., why a party wants to be determined as a parent, or the facts supporting custody orders). Leaving these blank or providing vague answers can lead to the court not having sufficient information to make a decision, potentially resulting in unfavorable orders or delays. Always provide clear, concise, and specific details as requested by the form prompts. AI can assist by prompting for necessary details based on the form's requirements.
Incorrectly Checking Boxes or Selecting Options
Selecting the wrong checkbox or option can fundamentally alter the request being made (e.g., requesting custody for the wrong party, or incorrectly stating parentage). This is a critical data entry error with significant legal consequences. Carefully read each question and ensure the box selected accurately reflects the intended request. AI tools can help by providing context or warnings when a selection might be inconsistent with other information provided.
Forgetting to Attach Required Documents
Forms like the UCCJEA Declaration (FL-105/GC-120) often require attachments (e.g., previous court orders, additional child information). Failing to attach these documents can lead to the form being incomplete and potentially rejected. Always review the form instructions for a list of required attachments and ensure they are included with the filing. AI tools can help by reminding users of required attachments based on the form type.
Inaccurate or Incomplete Child Information
Mistakes in listing children's names, birthdates, or ages can cause confusion and errors in legal orders. This is particularly problematic in custody and support matters. Ensure all children involved are listed accurately with their full legal names and correct birthdates. AI can help by standardizing date formats and ensuring all required child details are entered.
Improper Service Information
Failing to correctly fill out or understand the service requirements (e.g., who must be served, deadlines for service, proof of service) can invalidate the filing. For instance, the Notice of Related Case (CM-015) has specific service requirements. Always consult the instructions for each form regarding service. AI tools can help track deadlines and ensure all necessary parties are listed for service.
Overlooking or Misinterpreting Court Instructions and Notices
Forms often contain important notices or instructions (e.g., warnings about ex parte orders, child support implications, or the need for a Responsive Declaration). Ignoring these can lead to missed deadlines or misunderstandings of legal obligations. Read all notices and instructions carefully before completing and filing the form. AI can highlight critical notices and provide summaries of their implications.
Inconsistent Information Across Forms
Providing conflicting information between related forms (e.g., different dates of birth for a child on the Petition and the UCCJEA, or inconsistent requests on the Petition and the Request for Order) can cause confusion and rejection. Ensure all information is consistent across all documents submitted for the same case. AI can cross-reference information between forms to identify inconsistencies.
Failure to Specify 'Other' Fields
When an 'Other (specify)' option is provided, it means the pre-listed options do not cover the situation. Leaving the 'specify' field blank after checking 'Other' renders the selection incomplete and unhelpful. Always provide the requested specific details when this option is chosen. AI can prompt users to fill in the 'specify' field when 'Other' is selected.
