Authorization
Clear statement that the account holder directs the bank to block specific debit entries and the legal basis or account authorization being changed.
A properly completed block form establishes authorization, narrows which debits are prevented, and creates a record for banks or processors to act on. It reduces transaction risk and supports timely dispute resolution while documenting the account holder's intent under electronic signature laws such as ESIGN and UETA.
Individuals and organizations complete this form when they want to stop specific debit activity while preserving other payment permissions.
The form is also used by financial operations teams and compliance officers to document controls and to support audit trails for payment disputes or reconciliations.
