Extraction without verification produces an abstract that looks complete and contains silent errors. The quality check is what makes an abstract trustworthy, and it's a defined set of steps that runs after extraction on every lease. Skipping it is how the predictable abstraction errors slip into the record.
Check the Escalation Math
Verify that the recorded rent schedule reflects correct compounding. The standard test: if Year 1 rent is $50,000 with annual 3% increases, Year 5 should be approximately $56,275. A figure of $65,000 means the escalation was over-applied; a flat $50,000 means it was ignored. This single check catches the most common and most distorting abstraction error.
Verify Date Consistency
Commencement, rent commencement, expiration, and option deadlines should all be internally consistent. If commencement is January 1, 2023 and the term is 10 years, expiration should be December 31, 2032 — not 2031 or 2033. An inconsistency here signals an extraction error worth tracing back.
Reconcile Amendments and Flag Gaps
For every field an amendment affects, confirm the abstract reflects the amended term, not the original. And flag any field that was not found rather than leaving it blank — a blank field looks the same as a zero, while a flag explains that the term wasn't located. The AI agent runs all four checks automatically on every abstract and surfaces only the items that need human attention. It's demonstrated at omnionlinestrategies.com/ai-agent-cre-lease-abstraction.
