Check a rent ledger line by line before an eviction case, deposit dispute or move-out: have an AI match every charge and payment to the lease and receipts, and flag errors with the evidence: AI agent prompt

Worked example

A fictional business, so you can see what to paste in and what a good answer looks like. The example answer was written with AI help and its numbers and dates were checked; your AI's answer will be worded differently, so check it the same way.

Sample input (what you paste in)

I am the property manager. Location: Springfield.
Lease: rent $1,850 due the 1st, $50 late fee after the 5th, no other late-fee stacking; parking $50/mo; deposit $1,850; no rent increase this year.
Ledger pasted: Oct 1 rent $1,850 balance $1,850; Oct 6 late fee $50 balance $1,900; Oct 7 payment $1,850 balance $50; Oct 8 late fee $50 balance $100; Nov 1 rent $1,850 balance $1,950; Nov 3 payment $1,900 balance $50.
Proofs: Oct 7 e-transfer $1,850 ref 4412; Nov 3 e-transfer $1,900 ref 4419.

Example output (illustrative)

Rebuilt ledger
- October rent $1,850 due Oct 1. Payment $1,850 on Oct 7 (ref 4412) — after the 5th, so one $50 late fee is consistent with the lease. October should then show $50 remaining (the late fee), not a second late fee.
- November rent $1,850 due Nov 1. Payment $1,900 on Nov 3 (ref 4419) covers November rent plus the leftover $50 late fee from October if that $50 was valid. November should then show $0, not $50.

Differences
| Date | Ledger shows | Should show | Evidence |
| Oct 8 | second late fee $50 | $0 extra fee | Lease: no stacking; one fee after the 5th already posted Oct 6 |
| Nov 3 | $50 still owed after $1,900 | $0 if the Oct 8 fee is reversed | Proof ref 4419 = $1,900 |

Flags: duplicate/stacked late fee on Oct 8 ($50). No rent increase applied early. Parking not charged on this paste. Deposit not in these rows.

I would not send an arrears or eviction notice on a $50 balance until the Oct 8 fee is reviewed and the rebuilt balance is confirmed against the bank file.

Check before you use it: Rebuild from the lease and the proofs, not from the ledger's running total. A stacked late fee is a reason to pause, not to file.
