16 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.
Checks that the filer selects one—and only one—of the primary petition types: Dissolution (Divorce), Legal Separation, or Nullity. Selecting multiple (or none) makes the requested relief ambiguous and can cause rejection or require amendment. If validation fails, the system should block submission and prompt the user to choose exactly one primary case type.
Ensures at least one legal relationship box is checked (married, domestic partnership established in CA, or domestic partnership not established in CA) and that it aligns with the petition’s subject (marriage and/or domestic partnership). This is important because the court’s jurisdiction and required dates differ depending on whether the parties are married or registered domestic partners. If inconsistent (e.g., only domestic partnership checked but marriage dates provided as the basis), the system should flag the mismatch and require correction.
Verifies that residency requirements are satisfied for a divorce unless an exception applies (e.g., CA domestic partnership dissolution exception or same-sex marriage non-recognition exception). If the standard residency path is used, at least one of Petitioner/Respondent residency boxes must be checked; if an exception is checked, the system should require the related supporting fields (e.g., where each party lives, county where married). If validation fails, the system should prevent filing because the court may lack jurisdiction.
Checks that Superior Court county is provided and that court location fields (branch name, street address, city/ZIP, mailing address) are complete when required by the filing workflow. Proper venue and court identification are necessary for routing and docketing. If missing or malformed (e.g., city without ZIP), the system should require completion before submission.
Ensures Petitioner Name and Respondent Name are both present and appear to be full names (not blank, not identical, not placeholders like 'N/A'). Correct party identification is essential for service, case indexing, and matching to existing records. If validation fails, the system should block submission and request corrected names.
If a State Bar Number is provided, validates that attorney name and contact fields are also provided and that the bar number matches an expected pattern (typically 4–8 digits for CA). If no bar number is provided, the system should treat the filer as self-represented and avoid requiring firm fields unless entered. If inconsistent (e.g., bar number present but attorney name missing), the system should flag and require correction to avoid improper representation details.
