How lenders enforce TRID, Reg B and Reg X while the loan runs
Lenders and servicers miss the TRID three-business-day clock, the Reg B 30-day notice and the Regulation X loss mitigation deadlines because the rules sit in a binder while the file moves between teams by email. Callvu checks every application, disclosure, verification and referral against the regulation and your own policies before each step runs, so a missed disclosure or a skipped flood notice stops the file instead of surfacing at the audit.
The problem today
Most compliance is checked after the fact.By then, the damage is done.
Loan Estimate delivery
The application was complete on Monday, the disclosure desk saw it on Thursday, and the Loan Estimate went out on day four.
Loss mitigation application
The application was complete on the ninth call, and the foreclosure sale had already been scheduled.
Changed circumstance and revised Loan Estimate
The appraisal came in low on the 3rd, the processor emailed the desk on the 9th, and the revised Loan Estimate is a tolerance cure at closing.

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
TRID, Reg B, Reg X, Reg Z, HMDA, FCRA, E-SIGN, the Flood Disaster Protection Act, SCRA and the investor guidelines are loaded in Callvu Studio as policies and applied as steps that run. A step that breaks a rule does not run, so a completed file was compliant. Every run produces a Decision Trace with each evaluator's signal and the Completion Orchestrator's decision, and an Audit Trace with every checkpoint, delivery and signature, time-stamped.
- The TRID application date is detected when the six pieces of information arrive, and the Loan Estimate clock starts from it.
- A credit pull without a recorded authorization, a foreclosure referral under 121 days delinquent, or a closing without a flood policy is blocked.
- Delivery, receipt and acknowledgment of every disclosure are on the loan record for the examiner.
Operations
Processors stop re-keying the application into the LOS and stop chasing employers, insurance agents, appraisal management companies and flood vendors by phone. Each clock is visible on the case and routed before it runs out, and only the files the policy reserves reach the underwriter, the disclosure desk or the loss mitigation underwriter in the Decision Desk.
- One application record from the website, a loan officer, a broker or an AI agent, written to the LOS once.
- Documents, binders, appraisals and flood determinations are requested by link, read on arrival and checked against the guideline.
- Exceptions go to the right reviewer with the file and only the allowed outcomes.
IT
Callvu reads from and writes to the LOS, the pricing and fee engines, the flood and credit vendors and the servicing system by API and webhook. Nothing in that stack is replaced: the LOS stays the system of record and Callvu runs the regulated steps around it. Your own AI agent can start an application over MCP, with the sensitive data captured on a process-controlled screen outside the chat.
- Prefill from the LOS and the CRM, write back by API, with every write in the Audit Trace.
- The Decision Trace and the Audit Trace are pushed in real time to your GRC and BI tools.
- Regulations preloaded as policies; a new rule or an investor change takes about an hour to add.
Customer experience
The borrower answers only what the LOS does not already know, on their own phone, and the co-borrower completes their own sections on theirs. Disclosures arrive in the channel the borrower consented to, with one acknowledgment each, and nobody asks for the same pay stub twice.
- Applications, preapprovals and home equity lines prefilled for existing customers and finished in one session.
- A borrower who stops mid-application gets a link back to the same record, not a new form.
- The employer, the title company and the insurance agent each get their own link, so the borrower is not the courier.

Questions
What home lending buyers ask,answered plainly.
When does the TRID three-business-day clock start, and how does a lender prove it?
It starts when the lender holds the six pieces of information: name, income, Social Security number, property address, estimated value and loan amount. Callvu detects that moment in any channel, records the application date on the loan and opens the Loan Estimate case with the deadline visible. The Loan Estimate is prefilled from the LOS and the fee engine and delivered no later than the third business day, with delivery and receipt on the record.
How do we acknowledge a loss mitigation application within five business days and evaluate it on the Regulation X clock?
Callvu opens the application on the first request for assistance in any channel, classifies what the investor's evaluation needs and sends the written acknowledgment with the specific missing items within five business days of the application. Each item is chased through a link, read and checked on arrival, and the complete file goes to the loss mitigation underwriter in the Decision Desk inside the 30-day evaluation window. The completeness date is written to the servicing status, where the foreclosure referral gate reads it.
How do we meet the Reg B 30-day notice of action on every application?
The Reg B clock starts from the completed application, and Callvu shows the days left on every case. Verifications and orders run in parallel from the application, and the underwriter decides in the Decision Desk with the tests and only the allowed outcomes: approve, counter or decline with reasons. A declined application produces the adverse action notice from the recorded reasons inside the 30 days.
Can an AI agent start a mortgage application without putting the borrower's data in the chat?
Yes. The lender's own agent or Callvu AI starts the application over MCP, and identity, the Social Security number, consents and the HMDA demographic questions are captured on process-controlled screens outside the chat. The six evaluators judge the request before the first step, Callvu detects the TRID application date when the six pieces of information arrive, and the application lands in the LOS once, from whichever door it came.
What stops a loan from being referred to foreclosure under Regulation X?
Fewer than 121 days of delinquency, a complete loss mitigation application pending, an open appeal, an active plan, a bankruptcy stay or an SCRA protection. Callvu checks each one before referral, and the SCRA database again before sale, and the default manager decides in the Decision Desk with the checklist and the evidence. The attorney receives a complete package with the notices and their proof of timing.
How does a lender make sure the flood notice is sent and the flood policy is in force at closing?
The determination is ordered as soon as the property address is on the loan and read on delivery. If the building is in a special flood hazard area, the notice goes to the borrower a reasonable time before closing with the delivery time recorded, and the policy is chased from the agent by link. A missing determination, a late notice or a short policy holds closing, and the servicer inherits the policy and the monitoring.
