Can I end my "ACH authorization?”
Answer: Under the rules governing the ACH system, also called the Automated Clearing House network, for electronic withdrawals from consumer accounts, a valid “ACH authorization” must state clearly how it can be ended.
All lenders using the ACH system agree to abide by these rules.
You should not sign an ACH authorization that does not say clearly how you can revoke it. If you have signed an authorization that does not contain instructions on how to revoke it, you may have a right to tell your bank or credit union to reverse any account debits that the lender made based on that authorization .
