How banks and credit unions enforce Reg E, Reg DD, Reg B and CIP while the work runs
A bank's compliance is still checked after the fact: the Reg E dispute clock starts on a call nobody dated, the Reg DD notice goes out after the change hits the core, and the examiner rebuilds the evidence from emails. Callvu enforces each rule while the process runs, from account opening to disputes, loans and collections, so a disclosure is delivered before the step that needs it, every clock is tracked from the notice, and every run leaves a Decision Trace and an Audit Trace.
The problem today
Most compliance is checked after the fact.By then, the damage is done.
Debit card and EFT disputes
The claim was taken on a Thursday call, the written confirmation was requested, and nobody noticed the tenth business day pass.
KYC and CDD refresh
The refresh list is a spreadsheet, and the customers who matter most are the hardest to reach.
Credit card application
The branch application and the online application are two different processes, and the adverse action notice comes from a third.

The rules and the clocks
What is enforcedacross these processes.
The regulations below are preloaded in Callvu Studio as policies and applied as steps that run, not lines in a binder. A step that breaks a rule does not run, so a completed run was compliant. Each one links to the process pages that enforce it.
By role
What changesfor each team.
Compliance
The regulations preloaded in Callvu Studio and the bank's own policies run as steps, not as lines in a binder. Reg DD disclosures are delivered and acknowledged before an account opens, the Reg B 30-day notice of action is dated from the completed card or HELOC application, and a Reg E claim's clock starts at the notice, oral or written. A step that breaks a rule does not run, so a completed run was compliant.
- The Decision Trace shows each evaluator's signal and the Completion Orchestrator's decision before the first step.
- The Audit Trace holds every disclosure time, consent, signature and posting, pushed in real time to your GRC tools.
- The adverse action notice is produced from the decision record, with the specific reasons and the FCRA disclosures.
Operations
A dispute, a card application or a servicing change is one record from the door to the core, so nobody keys it twice. Provisional credit posts by the tenth business day where the investigation is open, the Reg DD change-in-terms notice goes out 30 days before the effective date, and a KYC refresh starts on the due date the risk rating sets. The exceptions the bank's policy reserves go to a named person in the Decision Desk with only the allowed outcomes.
- Complaints classified at capture, so a Reg E error notice or a regulator's complaint runs on its own clock from receipt.
- An elder exploitation hold decided by the fraud team with the state's disbursement delay tracked from the start.
- A collections arrangement booked in the core the moment it is agreed, so late fees stop.
IT
Callvu reads from and writes to the core, the loan origination system, the dispute system and the CRM by API and webhook. Those systems stay the systems of record; Callvu runs the process around them and writes the result once. An AI agent starts the same process over MCP, under the same evaluators, with identity, consent and signatures kept on process-controlled screens.
- Works with the cores and loan systems you already run, with no replacement.
- One write-back per step, retried if the core is unavailable, never a duplicate entry.
- Sensitive data stays out of the AI chat and on screens the process controls.
Customer experience
The customer starts in any channel and finishes in one session, on their own phone, from a link in a text or an email. What the bank already knows is prefilled, the dispute form or the application is signed on a process-controlled screen, and nobody asks for the same document twice. The customer sees what happens next and what is due.
- Start online, finish in the branch, with the same record on both screens.
- Disclosures, consents and signatures on the phone, timestamped in order.
- Provisional credit, a HELOC draw date and a payment arrangement confirmed in the same session.

Questions
What banking buyers ask,answered plainly.
When does the Reg E dispute clock start, and does it wait for a written claim?
It starts at the customer's notice, oral or written, which Callvu records at intake in every channel. The written claim is captured on the customer's phone, and provisional credit is not delayed for it unless the customer was told of that requirement at the notice. The investigation runs 10 business days, or 45 days with provisional credit by day 10, and the result notice goes out within three business days of completion.
How do we make sure account disclosures are delivered before an account is opened?
By the order of the process. The Truth in Savings, funds availability and electronic funds transfer disclosures are delivered and acknowledged, with timestamps, before the account is created in the core. The Audit Trace shows the order for every account, next to the CIP data and the verification result.
How is the Reg B 30-day notice of action kept on credit card and HELOC applications?
Callvu dates the application as complete when the last required item is verified, and the 30-day clock runs from that date. The consumer report authorization is captured on a process-controlled screen before the credit pull, and the adverse action notice is produced from the decision record with the specific reasons and the FCRA credit score disclosure. On a HELOC the early disclosures go out at application or within three business days, and no advance is made before the three-business-day rescission period ends.
How is the Reg DD change-in-terms notice enforced on account servicing changes?
The change type sets the notice rule and the advance period: at least 30 calendar days before an adverse change under Reg DD, and 21 days under Reg E for a change that increases fees or liability. The effective date cannot be earlier than the notice allows, and the change is written to the core only after the notice is out, so the Audit Trace shows which came first.
How long can a bank delay a disbursement for suspected elder financial exploitation, and what has to be reported?
The teller raises the concern with the facts, and the fraud team decides the hold in the Decision Desk with only the options the state's statute allows. The disbursement delay runs for the state's period, commonly 15 business days with an extension, tracked from the start of the hold, with the notices to the authorized parties and the state agency sent inside the statute's period. The adult protective services report and, where the threshold is met, the SAR within 30 calendar days are filed from the same case.
How Callvu runs it: Elder financial exploitation hold and report
How are Regulation F call limits and TCPA consent kept on collections contacts?
Status flags and contact consent are checked before any offer, call or text, and the contact history is checked against the Regulation F limit of seven calls in seven days per debt. A borrower can set up the arrangement from a link in a text without a collector, and the plan is written to the core and the collections system in one step so late fees stop.
Enforcement runs through the whole banking handoff
From the request to the system of record, with nobody re-keying.
