Yes! You can use AI to fill out Selbstauskunft - vertraulich -

This check ensures that the 'Geburtsdatum' (Date of Birth) for both the applicant and co-applicant is a valid date in the past and indicates the person is of legal adult age, typically over 18. It prevents data entry errors like future dates or typos that would result in an impossible age. If the date is invalid or suggests the applicant is a minor, the form submission should be rejected pending correction, as it's fundamental for identity verification and legal capacity.

This validation verifies that the 'Steueridentifikationsnummer' conforms to the official German format: an 11-digit number with specific rules, such as not containing a digit repeated more than three times consecutively. This is crucial for correct tax identification and regulatory reporting. A failure in this check would prevent the form from being processed correctly and could lead to issues with financial authorities, so the user must correct the number before submission.

This check calculates the sum of all individual income fields and compares it to the user-entered 'Summe Einnahmen'. It performs the same calculation for expenses against the 'Summe Ausgaben'. This is a critical logical check to ensure the financial data is arithmetically correct and not mis-totaled by the user. If the calculated sum does not match the entered total, an error is flagged, forcing the user to review and correct their financial figures for an accurate assessment.

This is a conditional validation that checks if the 'Branche' (Industry) field is filled out when the 'Erwerbssituation' (Employment Situation) is marked as 'selbstständig' (self-employed). The industry is a key data point for the bank to assess the risk associated with self-employment income. If an applicant is self-employed but does not specify their industry, the form submission will be blocked until this required information is provided.

This check validates that if a user ticks 'ja' (yes) to the question about having past legal or insolvency proceedings, the corresponding text field for details is not left empty. This information is vital for assessing creditworthiness and risk. A 'yes' answer without an explanation is incomplete and would halt the application process until the user provides the necessary details about the proceedings.

This logical check ensures the 'Beschäftigt seit / selbständig seit' (Employed/Self-employed since) date is not before the applicant's date of birth or before a reasonable working age (e.g., 16 years old). This prevents illogical data entry errors and ensures the employment history is plausible. An invalid date would trigger an error, requiring the user to correct their employment history.
