12 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.
This check sums the 'Share %' for all individuals designated as a 'Primary' beneficiary. The total must equal exactly 100% to ensure the entire account balance is allocated correctly. If the sum is not 100%, the form is considered incomplete and will be rejected, as it would create ambiguity in asset distribution upon the participant's death.
This validation sums the 'Share %' for all individuals designated as a 'Contingent' beneficiary. If any contingent beneficiaries are named, their shares must total 100%. This ensures a clear line of succession for the assets if no primary beneficiaries survive the account holder, preventing legal disputes. Failure to meet the 100% total will result in form rejection.
This check validates that the Social Security Number in the 'Participant Information' section is present and follows the 9-digit format (XXX-XX-XXXX or XXXXXXXXX). It is crucial for uniquely identifying the account holder for tax reporting and legal purposes. An invalid or missing SSN will prevent the form from being processed.
This validation ensures the participant's Date of Birth is entered in the required 'mm/dd/yyyy' format and represents a valid, logical date (e.g., not in the future or an unreasonable past date). This information is essential for identity verification and for determining eligibility for certain account actions. An incorrectly formatted or implausible date will cause the submission to fail.
The form explicitly states 'P.O. Box not accepted' for the residential address. This check scans the address field for 'P.O. Box' or similar variations to enforce this rule. A physical address is required for legal and compliance reasons, and using a P.O. Box will lead to rejection of the form.
This check confirms that the 'Participant's Signature' and the 'Date' fields in the authorization section are both filled. The signature legally authorizes the beneficiary change, and the date establishes when the change was made effective. Missing either of these critical elements invalidates the entire form and will halt processing.
