AI Lease Abstraction

Commercial leases can contain critical details spread across a base document, exhibits, amendments, side letters, and notices. An abstraction system attempts to locate key fields and organize them for portfolio management. Common fields include premises, rent, escalation formula, term, renewal and expansion options, notice deadlines, operating expenses, maintenance duties, and assignment restrictions. The hard part is not merely finding a number. A rent schedule can be amended later; an option may require specific notice; and a date may depend on delivery, business days, or another defined event. Extraction can miss handwritten changes, scanned pages, table structure, or exceptions in an addendum. A complete workflow identifies all documents for the lease, tracks precedence and effective dates, links every value to its clause, and flags uncertainty. Reviewers should reconcile important fields to the executed lease and later amendments, especially before sending notices, calculating rent, or exercising an option. An extracted deadline is not legal advice about whether notice is valid. It should be confirmed by the responsible property or legal professional. Data governance matters because lease files may include financial details and tenant information. Teams should retain source versions, audit corrections, and avoid silently overwriting conflicting values. AI can reduce repetitive lookup and create a searchable portfolio, but interpretation depends on contract language and governing rules. Reviewers should note unresolved conflicts explicitly.
