Closing Disclosure Review: A Pre-Closing Checklist With AI Checks

Compare the Closing Disclosure with the current settlement statement, payoff letters, lender instructions and approved fee evidence line by line. Give AI a controlled table of figures to flag missing lines, changed payees, rounding and unexplained differences. Then the escrow officer verifies every flag against the source document, resolves it with the right party and signs off the final version.

The useful AI output is an exception list, not a declaration that a closing is compliant. A figure can match in two documents and still be wrong because both copied an old payoff. Keep the most recent dated source beside each number, and record which version of the disclosure was sent for review.

Freeze the versions before checking a single amount

Ask the lender which Closing Disclosure is the operative draft and identify the settlement statement that supports it. Add the version timestamp, closing date, borrower and property reference to an internal cover sheet. If the statement changes while the comparison is running, stop, keep the old result for the audit trail and start a fresh pass. Mixing page two of one draft with cash to close from another creates a false reconciliation.

Collect the most recent Loan Estimate, signed contract and amendments, lender instructions, payoff demand with its good-through date, invoices or schedules for third-party charges, deposit evidence, credit instructions and disbursement ledger. An escrow team may already have a closing checklist; the escrow inbox and checklist workflow is the broader place to standardise document intake. Here the task is narrower: prove the figures on the disclosure agree with the evidence available before closing.

Give every source a short reference such as P1 for payoff, F2 for a fee invoice and C3 for the signed contract amendment. Enter its date and version in the comparison sheet. This makes an AI flag actionable: “Title search fee differs from F2 by $45” is useful; “some fees look unusual” is not. For a scan, have a person check that the extracted digits, decimal places and paid-by column match the page image before the comparison begins.

Do not upload an unredacted closing packet into a general consumer chat without your firm's approval, vendor review and authority to use it. A practical pilot uses synthetic figures or a redacted table with no account numbers, signatures, identity documents or wire instructions. If an approved business tool is used with live records, restrict access, retention and export according to the closing file's controls. AI cannot authenticate a payoff instruction merely because the document looks plausible.

Use a source-to-disclosure comparison sheet

The table below is a working format, not a substitute for the forms themselves. “Statement” means the final settlement ledger or statement your office uses to disburse. Some entries appear in different sections or under different labels. Map by economic meaning, payee, payer and timing; a text match on the description alone can conceal a duplicate fee or an omitted credit.

Build the sheet with columns for disclosure page and line, exact label, amount, borrower-paid/seller-paid/other-paid, settlement line, settlement amount, source ID, source date, difference, reviewer status and resolution note. Add a separate column for whether the amount is a debit or credit. A $600 seller credit entered as a positive borrower charge can appear numerically “equal” if the sign is lost. Use formulas or a calculator for arithmetic; ask AI to describe mismatches and missing evidence.

For each line, the officer first checks whether the disclosure and settlement statement refer to the same charge. Then compare both to the underlying authority. A service fee of $420 on the disclosure and $420 on the statement still needs the invoice or approved schedule. Conversely, a $15 difference may be legitimate if one document was updated and the other was not; mark it open until the revised disclosure and statement agree. Do not let a tolerance setting suppress a difference before its cause is known.

A complete illustrative tie-out

Consider an illustrative purchase with a $300,000 price, a $240,000 loan and a $30,000 deposit already held. The latest settlement statement lists borrower closing costs of $8,450, a $2,000 seller credit and a $1,200 lender credit. Ignoring other adjustments for this example, the buyer's remaining funds are $300,000 minus $240,000 minus $30,000 plus $8,450 minus $2,000 minus $1,200: $35,250. Put the same components beside the disclosure's cash-to-close figure. A total of $35,250 is necessary, but it does not prove that every line is correct; equal and opposite mistakes can cancel.

Now suppose the disclosure shows $8,495 of costs and $35,295 cash to close, while the statement still shows $8,450 and $35,250. AI should flag the $45 gap and identify the specific line rather than suggest that $45 is immaterial. The officer opens the dated title invoice: it shows $420, while the disclosure says $465 and the statement says $420. If the disclosure was keyed from an older schedule, request a correction from the party responsible for the disclosure, then rerun the calculation on the revised version. Do not simply alter the settlement ledger to force a match.

At the same time, the payoff demand says $86,000 through the planned disbursement date and $24 per additional day. If disbursement moves two days, the illustrative recalculation is $86,048. That change may affect seller proceeds and the statement even if borrower cash does not change. The officer obtains an updated demand or confirms the per-diem instruction through an authorised channel. AI can compute 2 × $24, but it cannot decide that an expired demand authorises payment.

Finally, suppose a deposit receipt proves $30,000, while the disclosure displays only $28,000. The resulting $2,000 cash-to-close difference is not a fee-tolerance question. It is a missing or misapplied receipt. Trace the receipt into the ledger, confirm whether another party holds part of it and update the disclosure through the established lender process. A signed-off comparison should show all three repairs separately: title charge, payoff date and deposit. A single “net difference zero” note would hide the work.

Have AI produce an exception ledger, not an approval

When the comparison sheet is prepared, ask the approved AI tool to work from the table rather than from a pile of PDFs. Its role is to identify unmatched labels, different figures, opposite signs, absent source IDs and inconsistent versions. Tell it to avoid legal conclusions, avoid filling blanks and return the exact input row identifiers. This limits the common failure where a model confidently states that a fee is within tolerance without knowing which estimate and circumstance apply.

Review this redacted closing comparison table as a difference finder.
For each row, return: row ID, disclosure amount and payer, statement
amount and payer, source ID and date, arithmetic difference, possible
cause, and the document a human must open. Flag missing or expired
evidence. Do not mark any charge compliant, invent a source, or approve
the closing. If labels differ, explain the proposed match and mark it
for officer confirmation.

Illustrative output for row F-07: “Disclosure $465 borrower-paid; statement $420 borrower-paid; source F2 invoice dated 12 May $420; difference +$45 on disclosure; open F2 and ask disclosure preparer whether an older schedule was used; status unresolved.” That is a usable exception. A bad output would be “Title fees are generally flexible, so proceed.” The latter has no source match and skips the person authorised to amend the form.

Another illustrative output for row P-03 might say: “Payoff $86,000 on both records; demand P1 good through 16 May; planned disbursement 18 May; request date confirmation and recalculate using documented per-diem.” Although the amounts agree, the date mismatch matters. The officer checks whether the planned disbursement date or demand changed. This illustrates why a purely numeric comparison misses settlement risk.

For a third AI check, feed only the line names and payer columns, with amounts hidden. Ask for possible duplicates and opposite-side entries. An illustrative finding is two “recording service” entries of $90, one borrower-paid and one seller-paid. The officer opens the two invoices; perhaps they are genuinely separate, perhaps one was copied twice. Do not delete one on the model's suggestion. The exact payee, service and contractual allocation decide it.

Review loan terms and estimate changes separately

The disclosure is more than a settlement cost list. Compare the loan amount, interest rate, term, payment features, projected payment, escrow information and prepayment penalty field to the lender's current instructions and the most recent Loan Estimate. The official Closing Disclosure explainer tells borrowers to check that the loan terms, estimated total monthly payment, closing costs and cash to close match the most recent Loan Estimate, so expect those four areas to draw questions. An escrow officer should route a loan-term discrepancy to the lender rather than try to “fix” it in the settlement statement. For lender-side controls, see the mortgage disclosure and audit workflow.

Illustrative term check: the estimate and lender instructions show a $240,000 loan, but page one of the disclosure says $242,000 while the settlement statement has $240,000. AI should report the three values and documents, then stop. The officer asks the lender which figure is authoritative and waits for the corrected package. Back-calculating the disclosure from the payment schedule would be speculative because the terms may have changed for a documented reason.

Fee change review is a second track. Official guidance divides closing costs into categories that cannot normally increase, can increase by no more than a cumulative 10% under applicable conditions, or can increase without that cap. The category depends on the charge and facts such as provider choice and valid changed circumstances. The official consumer guidance gives examples: fees paid to the lender, mortgage broker or an affiliate for a required service, and transfer taxes, sit in the no-increase group; recording fees are its example of the 10% group; prepaid interest, property insurance premiums and initial escrow deposits can change by any amount. Never apply “10% to every line”. Keep the current applicable estimate, the reason for any revision and the lender's documented assessment beside the change. The lender or qualified compliance reviewer decides tolerance treatment; the escrow officer raises an exception and confirms the resulting disclosure.

For example, an illustrative pair of charges estimated at $100 and $200 and finally charged at $115 and $205 has a combined increase of $20 on a $300 base, or about 6.7%. This arithmetic alone does not establish that the charges belong in the same cumulative category. A model can calculate the percentage and ask for classification evidence. It should not pronounce the increase permitted. If a fee might trigger a cure or corrected disclosure, refer it to the lender's compliance process.

Timing is also a source check. The rule says the borrower must receive the Closing Disclosure no later than three business days before consummation. A new three-business-day wait applies only when the APR becomes inaccurate, the loan product changes or a prepayment penalty is added. Other changes need a corrected disclosure that the borrower receives at or before consummation, and the borrower may ask to inspect the disclosure during the business day before consummation, which is one more reason to have the figures settled a day early. Record delivery and revision dates, ask the lender to decide the applicable timeline, and avoid telling a borrower that a revised number can never delay closing. The escrow instruction review covers the separate task of checking the written closing instructions.

Check cash movement without trusting a matching total

Reconcile the buyer's funds, seller proceeds, loan proceeds and individual disbursements. A neat total can conceal a wrong beneficiary. For each outgoing amount, identify the source obligation, approved payee name and the settlement line that funds it. Do not place account or wire details in an AI prompt. Verify payment instructions using your firm's independent callback and approval procedure, especially after a last-minute message changing a destination. AI text classification cannot authenticate a sender.

An illustrative seller-credit error is easy to miss. The contract amendment grants a $2,000 credit, the disclosure shows $2,000 in the seller-paid column, and the settlement statement shows a $2,000 buyer credit. The figures appear to agree, but the officer must check that the credit reduces the buyer's funds and seller proceeds exactly once. If the ledger also subtracts it under an “adjustment” line, the buyer benefits twice. Recompute both sides from the gross price rather than rely on a single cash-to-close cell.

Prorations deserve a similar two-sided check. Suppose a $600 expense is split 40% to one party and 60% to the other under an illustrative agreement. The expected allocation is $240 and $360. If the statement shows $240 and $340, the $20 remainder has vanished. AI can identify that $240 + $340 is $580, but the officer must inspect the dates, day-count method and agreement before assigning the difference. A simple totals check becomes a question with a named source.

Watch for items paid outside closing. An invoice may appear on the disclosure as paid before closing while the settlement ledger should not disburse it again. If AI matches only the fee label, it may consider the two documents consistent even though the ledger includes a second payment. Include the “paid before closing”, “paid at closing” and payer fields in the sheet. An illustrative $750 appraisal charge paid earlier should not also reduce available closing funds unless there is a separately documented charge.

Turn every flag into a documented resolution

Use four statuses: open, awaiting document, corrected and verified. A flag reaches verified only when the officer has reopened the source and final disclosure, not merely when someone emails “fixed”. Record the source ID, old and new amounts, who authorised the correction, the disclosure version and the time of sign-off. If a line changes after verification, return it to open. This is the safeguard against a late fee schedule overwriting a reviewed package.

A usable exception note reads: “F-07 title search: disclosure draft 3 $465; statement version 5 and invoice F2 $420; lender notified; disclosure draft 4 $420 received; statement version 5 unchanged; officer checked both on 18 May.” The note does not expose account data. Compare it with “title fee sorted”, which tells the next reviewer neither what changed nor which file to trust. Keep the supporting documents in the controlled closing record.

Assign ownership by issue. The lender resolves loan terms, disclosure generation and tolerance assessment. The settlement team confirms payoffs, allocations, fee invoices, deposits, ledger arithmetic and disbursement instructions within its authority. Counsel handles legal interpretation when a contract, title requirement or transaction structure is disputed. The title commitment exception review is related but should not be collapsed into this figure check. A clean disclosure does not prove that title conditions are cleared.

Before release, the officer verifies that no exception remains open, that the final disclosure and statement bear the versions recorded in the sign-off, that the cash-to-close amount agrees with the approved funding instruction, and that any correction has passed the lender's timing review. A second person can sample high-risk lines such as payoff, deposit, seller credit and wire payees. If time is short, escalate the unresolved item; speed is not evidence that a difference is harmless.

Measure whether the check improves the closing file

For a pilot, log the number of lines compared, AI flags, true differences, false alarms, missing sources and corrections made after sign-off. Count a flag as useful only if the officer could trace it to a document and resolve it. A high flag count may mean OCR failed or the mapping sheet is poor. If the same fee label produces repeated false matches, add a stable row ID or payee field rather than asking the model to “be more careful”.

Time the preparation and review separately. If preparing a redacted table takes 25 minutes and officer review takes 20, compare that with the previous manual process using the same case complexity. Do not claim saved time from one easy file. More valuable is whether a changed payoff date, duplicated charge or missing credit is caught before the final package is approved. Keep the decision log so a manager can inspect the claim without trusting the model's summary.

After two or three trial files, review the false negatives: choose a small set of known differences and confirm the AI marks all of them. Include a wrong sign, a changed payee, an expired demand, a missing deposit and a paired error that nets to zero. If the tool misses one, keep that check as an explicit human step. The officer's final signature means the actual documents were reconciled, the responsible parties answered the exceptions and the version released for closing is the one reviewed.
