U.S. federal Regulation E limits your liability for unauthorized debit card transactions from an Alliant Credit Union account to a maximum of $50 if you notify the credit union within two business days after learning of the loss or theft of your access device. If notified later, liability may extend to $500 or the amount of unauthorized transfers, whichever is less. Contact Alliant Credit Union immediately by phone or other available methods to report the issue and start the dispute process, as notice timelines directly affect your liability under 12 CFR § 1005.6.
This applies to electronic fund transfers, including debit card use from checking or savings accounts at federally insured credit unions like Alliant. Alliant must promptly investigate alleged errors per Regulation E requirements. This is not a credit card dispute, merchant refund, or other payment type.
Regulation E Controls Unauthorized Debit Disputes
Regulation E, under the Electronic Fund Transfer Act (12 CFR Part 1005), sets the federal rules for consumer liability and financial institution duties in unauthorized electronic fund transfers, including debit card transactions from Alliant Credit Union accounts.
Under § 1005.6, if you notify Alliant within two business days after learning of the loss or theft of your debit card or other access device, your liability is limited to the lesser of $50 or the amount of unauthorized transfers that occur before notice. If you notify after two business days but within 60 days after the statement showing the unauthorized transfer is sent, liability is capped at the lesser of $500 or the sum of unauthorized transfers before notice plus those made after until notice (up to the end of the 60-day period). Notice can be oral or written, per § 1005.6.
Financial institutions like Alliant must promptly investigate alleged errors, as outlined in § 1005.11(c) and summarized in NCUA guidance on Regulation E. No Alliant-specific timelines or provisional credit details are confirmed in official sources here--review your account agreement or contact Alliant directly.
| Liability Limit | Notice Timeline | Max Amount |
|---|---|---|
| Within 2 business days of learning of loss/theft | Prompt notice | Lesser of $50 or unauthorized amount before notice |
| After 2 business days | Within 60 days of statement | Lesser of $500 or unauthorized amounts (pre- and post-notice up to 60 days) |
What Does Not Control This Dispute
Regulation E governs debit card unauthorized transactions from bank or credit union accounts. It does not apply to credit card billing disputes under the Fair Credit Billing Act (FCBA), which have different timelines and protections.
Authorized peer-to-peer transfers (e.g., Zelle payments you approved, even if scammed) or merchant refunds follow separate rules, not Regulation E disputes. Wire transfers, remittances, and prepaid card specifics are also excluded. Visa or Mastercard debit network policies may influence Alliant's process but do not override federal Regulation E liability limits.
Next Steps to Dispute with Alliant Credit Union
Notify Alliant Credit Union as soon as possible after discovering the unauthorized transaction--delays increase potential liability under Regulation E § 1005.6. Use phone, app, online banking, or chat if available; oral notice starts the process.
Gather and provide:
- Transaction date, amount, and merchant details from your statement.
- Date you noticed the issue and learned of any card loss/theft.
- Confirmation you did not authorize the transaction (e.g., no recognition of merchant, no PIN/shared details).
Alliant must investigate promptly. Follow up for status updates. If unresolved after their process, escalate to regulators like the CFPB or NCUA with your dispute reference and evidence.
