A comprehensive checklist covering all 126 data fields required for a complete commercial lease abstract. This checklist ensures no critical clause is overlooked during the abstraction process, from parties and premises to options and red flags. Use it as a quality-control framework when reviewing AI-extracted data or performing manual abstraction.

Used by lease administrators, paralegals, and asset managers when abstracting a commercial lease for the first time or auditing an existing abstract for completeness and accuracy.
Lextract automatically extracts these fields from your lease PDF — eliminating the manual data collection underlying this checklist.
A manual lease abstraction for a standard 30-50 page commercial lease typically takes 2-4 hours for an experienced paralegal or lease administrator. Complex leases with numerous exhibits and riders can take 6-8 hours. Lextract reduces this to typically 5–15 minutes depending on document length and complexity, with human review of flagged fields taking 15-30 minutes.
The most frequently missed fields are buried in exhibits and riders rather than the main lease body: CAM exclusion lists, audit rights windows, holdover rent multiples, co-tenancy trigger conditions, and exclusive use carve-outs. Lextract checks all 126 fields including exhibit content.
For portfolios with more than 20 leases, a technology-assisted approach (like Lextract) is typically more cost-effective and consistent than manual or outsourced abstraction. Individual leases or small portfolios can be handled manually using this checklist as a guide.
Each amendment should be abstracted separately, noting which provisions of the original lease are modified. The abstract should reflect the as-amended position for all modified fields. Lextract processes the full lease package including amendments when uploaded together as a single PDF.
AI lease abstraction extracts 100+ structured fields from commercial lease PDFs in minutes. Learn how the technology works, what accuracy to expect, and how cost compares to manual services.
